The ratio would be 8:20 or 8 to 20
Answer: B
Step-by-step explanation:
7(-2) - 4(1) = -18
-14 - 4 = -18
-18 = -18
TRUE
(-2) + 12(1) = 10
-2 + 12 = 10
10 = 10
TRUE
Answer:
D: {-1,2,9,-4}
R: {6,0,-3}
Step-by-step explanation:
domain are the x-values
range are the y-values
When the triangle is a right triangle, you can use the Pythagorean theorem. The formula would be
c^2 = a^2 + b^2
If a = 21 and c=29, thus
b^2 = c^2 - a^2
b^2 = 29^2 - 21^2
b^2 = 400
b = square root (400)
b = 20 units.
Thus, the answer is <span>D) B = 400</span>
