Answer:
A = 20.5 sq units
Step-by-step explanation:
you have the height of 5 but need to figure out the base
we can use the Pythagorean Theorem two times to find it
1) a² + 5² = 7²
a² = 49-25
a = = · = 2
2) b² + 5² = 6²
b² = 36-25
b =
Base = 2 +
A = 1/2 x 5· (2 + )
A = 2.5 · (2 + )
A = 2.5(8.2)
A = 20.5
The answer should be. 5x=-12
well if you can find the slope then choose one of your ordered pair and plug them in tot he corresponding variable. since you don't know what the y intercept you basically find x which will be the y int.
18+15y-10
=18-10+15y
=8+15y
The largest domain for this is answer C [-1,1]
