Answer:
x = 47.4
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adj / hyp
cos x = 8.8 / 13
Take the inverse cos of each side
cos ^-1 ( cos x) = cos ^-1( 8.8 /13)
x = cos ^-1( 8.8 /13)
x =47.39633319
Rounding to the nearest tenth
x =47.4
Answer:
2x^3 1/4y
Step-by-step explanation:
<u>y^3</u>
4y^2
1/4 y
no x's to simplify
subtract the exponents for y
divide 1/4
Answer: (1,3) or x = 1 and y = 3
Step-by-step explanation:
The solution is the intersection thus the answer is (1,3) or x = 1 and y = 3
Answer:
It's D: 3x - 12 ≤ 8x + 13
Step-by-step explanation:
<u>The first step in this inequality is to take out the parentheses so you multiply 3 by x and -4.</u>
