Answer:
20
Step-by-step explanation:
4x + 3y = 5
We want to find 4(4x + 3y)
Replace (4x + 3y) in the expression with 5
4(5)
20
180 is the degrees a straight line segment is. This means that
4x + 3x + 2x = 180.
Since these all have the same variable (x), then you can add the coefficients. (4,3,2)
9x = 180
180/9 = x
X = 20
Answer: 15
Step-by-step explanation:
When you plot the points, it makes a rectangle. The length is 5 units and the height is 3 units. 5 times 3 is 15
Answer:
43
Step-by-step explanation:
you change the 1 hour into minute you and 60min to 25 minutes and then you subtract from 42 minutes to get the solution
The vertex-form equation is
y = a(x+1)² -16
Putting in the y-intercept values, we have
-15 = a(0+1)² -16
1 = a . . . . . . . . . . . add 16
Then the x-intercepts can be found where y=0.
0 = (x+1)² -16
16 = (x+1)²
±4 = x+1
x = -1 ± 4 =
{-5, 3}
