Step-by-step explanation:
- (-11)×[-52+(-17)-(-39)]
- -11×[-52-17+39)]
- -11×[-69+39]
- -11×[30]
- -330
Answer:
Monday: 4 hours = $36
Tuesday: 6 hours = $54
Wednesday: 5 hours = $45
His earnings are proportional because, for each hour, Richard earns $9. Using the formula y = kx, k (the constant) is always the same:
- 36 = k × 4 (k = $9)
- 54 = k × 6 (k = $9)
- 45 = k × 5 (k = $9)
Hope this helps!
Horizontal compression by factor 2 will do following.
After compression graph of the function is going to be closer to line of symmetry of the parabola. Values of y are not going to change, but values of x will be 2 times closer to the the line of symmetry.
For our case , line symmetry x=2,
points are going to be 2 times closer to this line.
1st point (4, -3) converts into (3,-3)
2nd point (-4,5) converts into (-1,5)
