A^2 + b^2 = c^2....where a and b are the legs, c is the hypotenuse
3^2 + b^2 = 7^2
9 + b^2 = 49
b^2 = 49 - 9
b^2 = 40.....take sqrt of both sides, eliminating the ^2
b = square root of 40 <==
The answer to this inequality would be -9
Answer:
g= -4
Step-by-step explanation:
-5g = 20
<u>Divide the -5 to both sides</u>
-5g / -5 = 20/ -5
<u>both -5 cancel out and g is left alone</u>
<u>20/-5 = -4</u>
<u>g= -4</u>
Answer:
2x-y=-1
Step-by-step explanation:
y + 9 = 2(x + 5)
y + 9 = 2x + 10 [distribute]
y = 2x + 1 [subtract 9 from both sides]
y - 2x = 1 [subtract 2x from both sides]
-2x + y = 1 [put x first]
2x - y = -1 [multiply by -1 to make x coefficient positive]
