Answer:
x = 19cm
Step-by-step explanation:
use pythagorean theorem:
a² - c² = b²
10² - 22² = b²
100 - 484 = b²
384 = b²
√384 = b
19cm = b or x
The equation would be Y=6.25x - 12.5 so the rate of change is 6.25.
6/11y=-18/22
Least Common Denominator is 11: 6/11y=-9/11
Multiply both sides by 11: 6y=-9
Divide both sides by 6: y=-9/6
Simplify: y= -3/2 OR -1.5
Answer:
(-3,5) ia the answer
Step-by-step explanation:
It is because when you reflect it across the x axis the first coordinate will be negative and the second number is positive since its in the second square of the graph, so it is more of a resonable guess.
