Answer:
Slope = -3, Y-intercept = -2, y = -3x -2
Step-by-step explanation:
There are multiple points plotted on the graph, but right now, we only need to focus on two.
(-2, 4) (-1, 1)
Using the ordered pairs, do delta y/ delta x to get the slope
(1-4)/(-1-(-2)
(-3)/(-1+2)
(-3)/(1)
Slope = -3
y = -3x + b
As shown on the graph, the y-intercept is -2. It is when x = 0
So, for the equation, substitute the found values.
y = -3x -2

D = -1 -2 4 = 3(-2)(-3) + 2(4)(1) + 1(-1)(-6)
1 -6 -3
- 1(-2)(1) - 3(4)(-6) - 2(-1)(-3)
= 18 + 8 + 6 + 2 + 72 - 6

What is the area, in square meters, of the shaded region in the diagram?
Answer:
Notice that the side length of the square is 38 m.
area of square = (side length)2 = (38 m)2 = 1444 m2
Notice that the diameter of the circle is 38 m .
And its radius = diameter / 2 = 38m / 2 = 19 m
area of circle = pi * radius2 = pi * (19m)2 = pi * 361 m2 ≈ 1133.54 m2
So......
area of shaded region = area of square - area of circle
area of shaded region ≈ 1444 m2 - 1133.54 m2
area of shaded region ≈ 310.46 m2
Step-by-step explanation:
Notice that the side length of the square is 38 m.
area of square = (side length)2 = (38 m)2 = 1444 m2
Notice that the diameter of the circle is 38 m .
And its radius = diameter / 2 = 38m / 2 = 19 m
area of circle = pi * radius2 = pi * (19m)2 = pi * 361 m2 ≈ 1133.54 m2
So......
area of shaded region = area of square - area of circle
area of shaded region ≈ 1444 m2 - 1133.54 m2
area of shaded region ≈ 310.46 m2

Which Of the following area models correctly describes the algebraic expression
x^2 + 2x + 3?
Answer:
C
Step-by-step explanation:
Solve for the variable
Answer:
40
Step-by-step explanation:
Try to get the variable alone by dividing 5/8 on both sides of the equations.
That cancels out the 5/8 on the left leaving u and the 25 on the right turns into 40. It turns into 40 because 25 divided by 5/8 equals 40.
Answer:
40
Step-by-step explanation:
Multiply both sides by 8/5
Tracy has to buy comic books to pay for a movie ticket. Each comic book costs 10$. Write an inequality that can be used to determine how many comic books, b, tracy can buy.
Answer:
c=b
Step-by-step explanation:
b is not equal to c.
Answer:
$35 - 3b is greater or equal to $10
Step-by-step explanation:
Remember that:
Dollars spent on an item = (cost of one item)*(number of items), so –
Dollars spent on comic books = $3b
“Tracy has $35 to buy comic books and to pay for a movie ticket” means
(Money spent on comic books) + (money spent on movie ticket) ≤ $35
(Money spent on comic books + $10 ≤ $35
$3b + $10 ≤ $35 [just substituting values]
Now, we must modify the inequality, so remember the rules –
$35 ≥ $3b + $10 [reverse right-to-left reverses the sense of the inequality;
$35 is greater or equal to the total amount Tracy can spend]
$35 - $3b ≥ $10 [subtract positive 3b from both sides
keeps the sense of the inequality]

C is 5, 1
What is m
А
105°
86°
C
E
137°
D
Answer:
122 degrees
Step-by-step explanation:
*A pentagon has a total of 540degrees
1st step: take all of the degrees and add them up:
105 + 90 + 86 + 137 = 418
2nd step: subtract the sum from 540:
540 - 418 = 122
The missing angle is 122 degrees
Answer:
∠ C = 122°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 5, then
sum = 180° × 3 = 540°
Sum the given angles and equate to 540°
∠ C + 137° + 86° + 105° + 90° = 540 , that is
∠ C + 418° = 540° ( subtract 418° from both sides )
∠ C = 122°
Write two division equations for each multiplication equation. 15⋅25=6 15 ⋅ 2 5 = 6 6⋅43=8 6 ⋅ 4 3 = 8 16⋅78=14
Answer:
[tex](a)[/tex] [tex]\frac{30}{5} = 6[/tex] and [tex]\frac{60}{10} = 6[/tex]
[tex](b)[/tex] [tex]\frac{24}{3} = 8[/tex] and [tex]\frac{96}{12} = 8[/tex]
[tex](c)[/tex] [tex]\frac{112}{8} = 14[/tex] and [tex]\frac{28}{2} = 14[/tex]
Step-by-step explanation:
Given
[tex](a)\ 15 * \frac{2}{5} = 6[/tex]
[tex](b)\ 6 * \frac{4}{3} = 8[/tex]
[tex](c)\ 16 * \frac{7}{8} = 14[/tex]
Required
Write 2 division equations
[tex](a)\ 15 * \frac{2}{5} = 6[/tex]
Express 15 as 15/1
[tex]\frac{15}{1} * \frac{2}{5} = 6[/tex]
Multiply numerator and denominator
[tex]\frac{30}{5} = 6[/tex] --- This is (1)
Multiply the fraction by a common term (e.g. 2)
So, we have:
[tex]\frac{30*2}{5*2} = 6[/tex]
[tex]\frac{60}{10} = 6[/tex] ---- (2)
[tex](b)\ 6 * \frac{4}{3} = 8[/tex]
Express 6 as 6/1
[tex]\frac{6}{1} * \frac{4}{3} = 8[/tex]
Multiply numerator and denominator
[tex]\frac{24}{3} = 8[/tex] --- This is (1)
Multiply the fraction by a common term (e.g. 4)
So, we have:
[tex]\frac{24*4}{3*4} = 8[/tex]
[tex]\frac{96}{12} = 8[/tex] ---- (2)
[tex](c)\ 16 * \frac{7}{8} = 14[/tex]
Express 16 as 16/1
[tex]\frac{16}{1} * \frac{7}{8} = 14[/tex]
Multiply
[tex]\frac{112}{8} = 14[/tex] ---- This is (1)
Divide the fraction by a common term (e.g. 4)
[tex]\frac{112/4}{8/4} = 14[/tex]
[tex]\frac{28}{2} = 14[/tex]

Answer:
1 = 3
2 = 6
3 = 9
Step-by-step explanation:
for every # it is multiplied by 3 (ex. 7 • 3 = 21, 8 • 3 = 24, ect.)
therefore if it is multiplied by 3 each time
then 1 • 3 = 3
2 • 3 = 6
and 3 • 3 = 9
