Answer:
y=7x-4
Step-by-step explanation:
since the slope is m, you replace m for 7 in the equation y=mx+b. and since the y-intercept is -4, you just do -7 after the slope
First calculate the difference between the prices of the shoes
67-52= 15
Next, divide the difference by 52 (the original price)
15/52 = 0.28846
Multiply by 100 to get the percentage (rounded to nearest percent)
0.28846 = 28.8% = 29% rounded
The price of the pair of shoes increased by 29% (rounded).
Hope this helps! :)
290 * 7 = 1400 + 630 = 2,030
2030 - 7 = 2,023
Answer:
10y²/3x³
Step-by-step explanation:
You want to multiply the numerator times the numerator, and the denominator times the denominator.
This makes it 20y⁴x²/6x⁵y²
You can then simplify it further to 10y⁴x²/3x⁵y²
You can than subtract the power for futher simplification so the final answer is
10y²/3x³
B. 15 because
-18+x=-3
X= -3 + 18
X = 15
