Answer:
f(- 2) = 10
Step-by-step explanation:
Substitute x = - 2 into f(x) , that is
f(- 2) = (- 2)² + 6 = 4 + 6 = 10
Answer:
Dryer = 320
Washer = 960
Step-by-step explanation:
Washer + Dryer = 1280
Let,
Dryer = x
Washer = 3x
3x + x = 1280
4x = 1280
x = 320
Washer = 3x = 3(320)=960
960 + 320 = 1280
Thus,
Dryer = 320
Washer = 960

Answer:3x+y=-8
Step-by-step explanation: If you were to solve each equation by graph the slope would be negative 3
Answer:
The answer is y=7x-15
Step-by-step explanation:
The formula for slope is y=mx+b where m is the slope, or the rate of change, and b is the y-intercept, or the initial value, which is the point where x=0.
The rate of change, or slope, is 7, so m will be replaced with 7.
-15 is the y-intercept, so b will be replaced with -15.
Therefore, the slope-intercept form is y=7x-15.
