36 x 3/9.
3/9 = 0.33
0.33 x 36 = 12
The First expression is 13 to the 1st power. the second expression is 13 to the -22nd power. third expression is 13 to the 15th power fourth expression is 13 to the 7th power.
24. This answer would be A, or y=x^4. When the exponent is used, in each ordered pair, every time x is increased by 1, y is multiplied by 4, like in every exponent. 1 x 4 = 4. 4 x 4 = 16. 16 x 4 = 64. 64 x 4 = 256.
25. The answer is C, or C(n) = (0.90 + n) - 0.40. Your coupon subtracts 40 cents off of your total amount of cans of tuna, but the amount of tuna cans that you will buy is not stated, so that unknown number is n.
Parallel to : y = 1/2x - 8
Passes through (-6, -17)
Our given slope is 1/2.
Plug the given coordinates into point-slope form.
y - y₁ = m(x - x₁)
y - (-17) = 1/2(x - (-6))
Simplify.
y + 17 = 1/2(x + 6) ← Your answer.
However, sometimes teachers want this simplified even further.
So, simplify this.
y + 17 = 1/2x + 3
Subtract 17 from both sides.
y = 1/2x + 3 - 17
Simplify.
y = 1/2x - 14 ← Slope-intercept form.
Standard form → -1/2x + y = -14
~Hope this helped!~
