Answer:
27
Step-by-step explanation:
Given
- 3w - 5p ← substitute w = - 4 and p = - 3 into the expression
= - 3(- 4) - 5(- 3 )
= 12 + 15
= 27
Answer:
b. -(x - 7)(x + 10)
Step-by-step explanation:
-x² - 3x + 70
-(x - 7)(x + 10)
Answer:
Step-by-step explanation:
Answer: the length of each of the congruent sides is 29 inches.
The length of the third side is 22 inches.
Step-by-step explanation:
In an isosceles triangle, two sides are equal. The base angles are also equal.
Let x represent the Length of each of the congruent side.
The congruent sides are 7 inches longer than the third side of the triangle. This means that the length of the third side of the triangle is
x - 7
The formula for determining the perimeter of a triangle is
a + b + c
Where a, b and c are the length of each side of the triangle.
If the isosceles triangle has a perimeter of 80 inches, it means that
x + x + x - 7 = 80
3x - 7 = 80
3x = 80 + 7 = 87
x = 87/3 = 29 inches
The length if the third side would be
29 - 7 = 22 inches
Answer:
1. D y = 8
2. C y = −8
Step-by-step explanation:
1.
Both points have y-coordinate 8, so the line is horizontal.
A horizontal line has equation
y = k
where k is the y-coordinate of all of its points.
The y-coordinate of all points on this line is 8.
Answer: y = 8
2.
A line with 0 slope is a horizontal line. All points on a horizontal line have the same y-coordinate.
A horizontal line has equation
y = k
where k is the y-coordinate of all of its points.
The y-coordinate of the given point is -8, so all points must have -8 as the y-coordinate.
Answer: y = -8
