The x-intercept of the equation is 13 and its interpretation in the context of the problem is the number of time in hours for which Lily left her house.
What is x-intercept?In Mathematics, the x-intercept can be defined as the point at which the graph of a function crosses the x-coordinate (x-axis) and the value of "y" is equal to zero (0).
Next, we would determine the number of time for which Lily has left her house since in the morning by substituting the value of B with zero (0) as follows:
B = -4t + 52
0 = -4t + 52
4t = 52
Time, t = 52/4
Time, t = 13 hours.
Therefore, the x-intercept of the given equation is (0, 13).

Can anyone write the equation of the graph?
The equation of the absolute value function graph is: y = |x - 3| + 5.
How to Write the Equation of the Graph of Absolute Value Function?The equation, y = a|x – h| + k, represents the equation of an absolute value function in the vertex form, where:
(h, k) = vertex of the graph a = determines if the graph opens up or opens down.h = horizontal translation factor (this determines how far left or right the parent function is translated)k = vertical translation factor (this determines how far up or down the parent function is translated)We are given the following from the graph:
Vertex (h, k) = (3, 5)
Plug in the values of h and k into the equation, y = a|x – h| + k:
y = a|x - 3| + 5
A point on the graph is (5, 7). Find the value of a by substituting (x, y) = (5, 7) into y = a|x - 3| + 5:
7 = a|5 - 3| + 5
7 = a|2| + 5

What is an equation of the line that passes through the points (4, -2) and (2, 3)
The slope-Intercept form of the given line is y=1.5x.
What is the equation of a line?A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of line is given by,
y =mx + c
where,
x is the coordinate of the x-axis,
y is the coordinate of the y-axis,
m is the slope of the line, and
c is y-intercept.
The given line passes through (4, -2) and (2, 3). Therefore, the slope of the given line can be written as,
Slope of the line, m = (-2 - 3)/(4 - 2)
= 3 / 2
= 1.5
Now, the equation of the line passing through (2, 3) can be written as,
y = mx + c
(3) = 1.5(2) + C
3 = 3 + C
3 - 3 = C
C = 0
Substitute all the value in the equation of the line,
y = m(x) + c
y = 1.5(x) + 0
y = 1.5x
Hence, the equation of the given line is y=1.5x .

A bakery sells 4 dozen cupcakes every 3 hours. If the bakery is open 8 hours each day, how many days does it take to sell 640 cupcakes?
5 days does it take to sell 640 cupcakes.
Given:
A bakery sells 4 dozen cupcakes every 3 hours.
If the bakery is open 8 hours each day.
4 dozen cupcakes = 4*12 cupcakes
= 48 cupcakes
48 cupcakes = 3 hours
divide by 3 on both sides
3hours/3 = 48/3 cupcakes
1 hour = 16 cupcakes
Number of cupcakes for 8 hours = 8 * 16 = 128 cupcakes.
128 cupcakes sells in one day.
To sell 640 cupcakes = 640/128

the monthly cost (in dollars) of water use is a linear function of the amount of water used (in hundreds of cubic feet, hcf). the cost for using 17 hcf of water is 36.43, and the cost for using 28 hcf is 54.58 . what is the cost for using 24 hcf of water?
The cost for using 24 HCF water is 47.98(in dollars) by using a linear function.
What is meant by linear function?The term linear function in mathematics refers to two distinct but related concepts.
A linear function in calculus and related fields is a function whose graph is a straight line, that is, a polynomial function of degree zero or one. The term affine function is frequently used to distinguish such a linear function from the other concept.
A linear function is a linear map in linear algebra, mathematical analysis, and functional analysis.
The monthly cost of water use is a linear function: y=mx +b, where x represents HCF and y represents the cost of using. For example, if the cost of using x=17 HCF of water is $y=36.43, this means
that is a point (17,36.43)
the cost for using x=28 HCF is $y=54.58, means
that is a point (28, 54.58)
By using the above points we find slope m,
m=((54.58-36.43)/28-17)
m=1.65
=>y=1.65x+b
Now, we have to find the b point by using above point,
36.43=1.65*17+b
36.43=28.05+b
34.63-28.05=b
b=8.38
y=1.65x+8.38
When x=24,
y=1.65(24)+8.38
y=47.98
The cost for using 24 HCF of water is 47.98

The percentage increase in the number of pieces she saws on that day is 40%.
Here it is given that a seamstress sews 55 pieces per day.
But on a certain day, 77 pieces were sewn.
We have to find the percentage increase in the number of pieces she sews on that day.
So first we have to find the increase in the number of pieces she sews.
Increase in the number = 77 - 55
= 22
The original number per day = 55
Formula to find the percentage increase in the number.
Percentage increase = Increase in number/ original number × 100
Now putting the values in the equation:
Percentage increase = 22 / 55 × 100
= 2/5 × 100
= 40%
Therefore there is a 40% increase in the number of pieces.

The length of the base of an isosceles triangle is x. The length of a leg is 4x-4. The perimeter of the triangle is 37. Find x.
Answer:
x = 9
Step-by-step explanation:
According to the question,
Perimeter of an isosceles triangle = 37
Length of the base = x
Length of one leg = 4x - 4
As it is an isosceles triangle so length of the other leg will also be 4x - 4.
Perimeter of triangle is equal to sum of all the lengths of the triangle.
[tex] \therefore [/tex]
[tex] \rm \implies Length \: of \: base + Length \: of \: one \: leg + Length \: of \: other \: leg = 37
\\ \\ \rm \implies x + 4x - 4 + 4x - 4 = 37
\\ \\ \rm \implies 9x - 8 = 37 \\ \\ \rm \implies 9x = 37 + 8 \\ \\ \rm \implies 9x = 45 \\ \\ \rm \implies x = \frac{45}{9} \\ \\ \rm \implies x = 5

D) y= 5/7x-4/7
E) y= 1/7x+3
Answer:
Step-by-step explanation:
The answer is D.
The rule for perpendicular lines is that the slope will be the negative reciprocal. Because this equation is in slope-intercept form, the coefficient of x is the slope. -7/5 becomes 5/7. Our new equation is y=5/7x+b. Plugging in (5,3), we see that b is equal to -4/7. Our equation is then y=5/7x-4/7

Step-by-step explanation:
Solving quadratic equation and linear equation:
2x² + y² = 19 -----------------(I)
x + 3y = 0 -----------------(II)
x = -3y --------------(III)
Substitute x = -3y in equation (I) and we can find the value of y.
2(-3y)² + y² = 19
2*9y² + y² = 19
18y² + y² = 19
Combine like terms,
19y² = 19
y² = 19 ÷ 19
y² = 1
y = √1
y = ±1
Substitute y = ±1 in equation (III) and find the value of x.
When y = 1,
x = -3*1
x = -3
When y = -1,
x = -3*(-1)
x = 3

For each sequence that is neither arithmetic nor geometric, how can you change a
single number to make it an arithmetic sequence? A geometric sequence?
If the common difference between every term in a sequence is the same, the sequence is arithmetic. If all of the terms in a sequence have the same common ratio, the sequence is geometric.
Take a look at the sequence 2,4,6,8, and note how each new term is created by adding a constant term, in this case 2, to the one before it.
For instance, the number 4 is created by adding 2 to the previous phrase, in this case the number 2.
Similar to how 2 + 4 = 6, another number is obtained by adding 2 to 4.
As a result, the sequence is arithmetic since there is a common difference between the sequences, which in this case is 2.
Take the numbers 3, 6, 12, etc.
Keep in mind that the ratio of the following and preceding terms is the same (6/3=2 and 12/6=2).
Such a sequence is referred to as a geometric sequence, and the constant ratio is known as the common ratio of the sequence and is typically indicated by the symbol r.
What is arithmetic sequence?
An ordered group of numbers with a shared difference between each succeeding word is known as an arithmetic sequence.

hey I need this answer and puzzle 4 and 5 you got these things?
Step-by-step explanation:
please
The measure of angles A, B , C and D°are 36°, 63°, 71° and 111° respectively
How to determine the measure of the indicated angle?
To find the measure of angles of A, B, C and D, you need to apply some of the angle geometry concepts as follows:
1. m<A
(x+24)° and A = 3x
Since alternate angles are equal, thus:
3x° = (x+24)°
3x -x = 24
2x = 24
x =24/2 = 12
Also, A = 3x = 3(12) = 36°
2. m<B
B = 10x-27 and 7x
Since corresponding angles are equal, thus:
10x -27 = 7x
10x -7x = 27
3x = 27
x = 27/3 = 9
Also, B = 10x -27 = 10(9) -27 = 90-27 = 63°
3. m<C
C = (5x+1)° and (6x-13)°
Since corresponding angles are equal, thus:
(5x+1)° = (6x-13)°
6x -5x = 13+1
x = 14
Also, C = 5x+1 = 5(14) + 1 = 70+1 = 71°
4. m<D
(6x+3)° and D = (4x+39)°
Since alternate angles are equal, thus:
6x+3 = 4x+39
6x-4x = 39-3
2x=36
x = 36/2 =18
Also, D = 4x+39 = 4(18) + 39 = 72+39 = 111°
Therefore, the m<A = 36°, m<B = 63°, m<C = 71° and m<D =111°. Since B, A, H and E correspond to m<A, m<B, m<C and m<D respectively, so type BAHE in the answer box
