i need help with my homework, and the question is:
what is the equation of line? write in the form y=mx+b
it passes through (2,-5) and its x-intercept is 4.
Answer:
When the line intercepts the x axis, this means that y will be 0.
therefore the 2 coordinates the line passes through are (2,-5) and (4,0)
given equation of line:
y=mx+b
where m = slope
b = y-intercept.
Let (2,-5) and (4,0) be (x1,y1) and (x2,y2) correspondingly.
slope of line = y1-y2 / x1 - x2
[tex] = \frac{ - 5 - 0}{2 - 4} \\ = \frac{ - 5}{ - 2} \\ = \frac{5}{2} [/tex]
Now substitute x = 4, y = 0 and m = 5/2 into equation of line to find b.
[tex]0 = ( \frac{5}{2} )(4) + b \\ 10 + b = 0 \\ b = 0 - 10 \\ = - 10[/tex]
therefore equation of line will be:
[tex]y = \frac{5}{2} x - 10[/tex]

20/22 is the tangent value of which reference angle
Answer:
X
Step-by-step explanation:
Mathematically, the tangent of an angle is the ratio of the opposite side to the adjacent side
So, for 20/22; 20
is the opposite while 22 is the adjacent
The opposite side simply refers to the side that faces the given angle
We have the opposite side here as facing the angle X and that makes X the correct answer
find the greatest value of x

Lana is putting lace trim around the
border of a circular tablecloth. The
tablecloth has a diameter of 1.2 meters.
To the nearest meter, what is the least
amount of lace she needs? Use 3.14 for T.
Answer:
[tex]1.2 \times 3.14[/tex]
Step-by-step explanation:
The ratio of a circumference to its diameter is equal to an irrational number, called pi, roughly equal to 3.14, denoted by symbol
[tex]\pi[/tex]
Therefore, knowing the diameter d, the circumference is equal to d*π

Describe how you can find the number of solutions of two or more
equations by using the slope and the y-intercept. Use vocabulary terms in
your description.
Answer:
Suppose we have a system of two linear equations, this can be written as:
y = a*x + b
y = c*x + d
Now, we have 3 possible cases here.
The solutions of the system are the points where the graphs of the linear equations do intersect.
Then, if for example, we have two parallel lines (two parallel lines never intersect) we have no solutions.
And we know that two lines are parallel if they have the same slope and different y-intercept.
Then the system:
y = a*x + b
y = a*x + c
has no solutions.
If we have both equal lines, then the lines intersect in infinitely many points, meaning that we have infinite solutions, then the system:
y = a*x + b
y = a*x +b
has infinite solutions.
And if the lines intersect only one time we have one solution, and this happens when the slopes are different, so the system:
y = a*x + b
y = c*x + d
has only one solution.
Now, if we have more equations:
y = a*x + b
y = c*x + d
y = k*x + n
We have more equations than variables, then this system only has one solution of the 3 lines intersect at the same point, which is really rare.
One case where we have a solution here is if the 3 equations have the same y-intercept:
y = a*x + b
y = c*x + b
y = d*x + b
where the solution is the point (0, b)
Of course, there are other possible solutions, but these are not as formulaic as this ones.

Which expression represents the perimeter of the following triangle?
a
19 = 548 and a
33 = 968
Find a
27
Answer:
The value of a₂₇ is 788
Step-by-step explanation:
a₁₉ = 548
a₃₃ = 968
Now,
a₁₉ = 548 can be written as
a + 18d = 548 ...(1) and
a₃₃ = 968 can be written as
a + 32d = 968 ...(2)
Now, from equation (2) we get,
a + 32d = 968
a + 18d + 14d = 968
548 + 14d = 968 (.°. a + 18d = 548)
14d = 968 - 548
14d = 420
d = 420 ÷ 14
d = 30
Now, for the value of a put the value of d = 30 in equation (1)
a + 18d = 548
a + 18(30) = 548
a + 540 = 548
a = 548 - 540
a = 8
Now, For a₂₇
a₂₇ = a + 26d
a₂₇ = 8 + 26(30)
a₂₇ = 8 + 780
a₂₇ = 788
Thus, The value of a₂₇ is 788

PLLSSSSS HELPPPP I DONT GET THIS AT ALL
Answer:
[tex]y\leq 4[/tex]
Step-by-step explanation:
The range is about the y values, and by looking at this parabola we can see that the maximum value is a 4. So the range would be the maximum and below (where the parabola extends to). So the values in the range would be equal to 4 and less than since the parabola is negative.

Answer:
175.2 square feet
Step-by-step explanation:
The lateral area is the total area of the side faces. It excludes the area of the top and bottom "bases" of the prism.
It can be found by adding the areas of the four rectangles. The two you can't see have the same areas as the two you can see.
Since the height of each rectangle is 4 feet. the total area will be the product of that and the perimeter of the prism.
LA = Ph . . . . perimeter times height
LA = 2(L+W)h . . . . the perimeter is twice the sum of length and width
LA = 2(12.3 ft + 9.6 ft)(4 ft) = 2(21.9 ft)(4 ft) = 175.2 ft²
The lateral area of the prism is 175.2 ft².
__
The attachment shows scribbling on two of the faces that contribute to the lateral area. As stated above, the other two faces are the same size as these.

Answer:
32π + 96 [tex]cm^{2}[/tex] = exact area
196.48 [tex]cm^{2}[/tex] = area to the nearest 100th
Step-by-step explanation:
Area of semicircle = 1/2π[tex]r^{2}[/tex] = 1/2π[tex]8^{2}[/tex] = 1/2π(64) = 32π
Area of triangle = 1/2bh = 1/2(16)(12) = 96
Total area = 32π + 96 [tex]cm^{2}[/tex]
or 100.48 + 96 = 196.48 [tex]cm^{2}[/tex]
32π + 96 cm² = exact area
196.48 cm² = area to the nearest 100th
What is a semi-circle?A semicircle is a one-dimensional locus of points that makes up one half of a circle in mathematics. A semicircle's whole arc is always 180 degrees long. It just has one symmetry line.
Given
Area of semicircle = 1/2πr² = 1/2π(8)² = 1/2π(64) = 32π
Area of triangle = 1/2bh = 1/2(16)(12) = 96
Total area = 32π + 96 cm²
or 100.48 + 96 = 196.48 cm²

Step-by-step explanation:
whats the answer for y=-[tex]\frac{2}{3}[/tex]x+4 and y=[tex]\frac{1}{3}[/tex]x-2
Step-by-step explanation:
[tex]y = -\frac{2}{3}x + 4[/tex]
[tex]y = \frac{1}{3}x - 2[/tex]
Since both equations are set equal to [tex]y[/tex], we can take the right-hand side of each equation and set them equal to each other to solve for [tex]x[/tex]:
[tex]-\frac{2}{3}x + 4 = \frac{1}{3}x - 2[/tex]
[tex]-\frac{2}{3}x - \frac{1}{3}x = -2 - 4[/tex]
[tex]-x = -6[/tex]
[tex]x = 6[/tex]
Now we can plug this value into either equation to solve for [tex]y[/tex]:
[tex]y = \frac{1}{3}x - 2[/tex]
[tex]y = \frac{1}{3}(6) - 2[/tex]
[tex]y = 2 - 2[/tex]
[tex]y = 0[/tex]
So the solution to the system of equations is [tex](6, 0)[/tex]
