Answer:
15%
Step-by-step explanation:
To start off, we need to divide 136 by 160 to find a decimal value.
136/160 = .85
This shows us that the value of the lawnmower is 85% of 160. To finish the problem, we simply subtract .85 from 1.
1 - .85 = .15
If we turn .15 into a percentage, we get 15%. We now know that the lawn mower decreased by 15%.
Answer:
b. y+7=5x
Step-by-step explanation:
a. 1-3x^2 is a quadratic
b. y+7=5x is a linear function: y = 5x - 7
c. x^3 + 4 = y is a cubic function
d. 9(x^2-y) = 3 is a quadratic function
e.y-x^3=8 is a cubic function
---------------------
Let's solve for k.
3kx+24=9x
Step 1: Add -24 to both sides.
3kx+24+−24=9x+−24
3kx=9x−24
Step 2: Divide both sides by 3x.
3kx / 3x = 9x−24 / 3x
k = 3x−8 / x
Answer:
k = 3x−8 / x
-----------------------------------
Let's solve for x.
3kx+24=9x
Step 1: Add -9x to both sides.
3kx+24+−9x=9x+−9x
3kx−9x+24=0
Step 2: Add -24 to both sides.
3kx−9x+24+−24=0+−24
3kx−9x=−24
Step 3: Factor out variable x.
x(3k−9)=−24
Step 4: Divide both sides by 3k-9.
x(3k−9) / 3k−9 = −24 / 3k−9
x = −8 / k−3
Answer:
x = −24 / 3k−9
Hope i helped!
5 - (-4) = 9
(-4) - 7 = -11
So, the slope of this line is 9/-11.
