Answer:
The answer is 8.237×10^-3
Answer:
x=18
Step-by-step explanation:
y²+y²=(9√(2))²
2y²=81*2
y²=162/2
y²=81
y=9
hypotenuse: 2y=x 2*9=18
x=18
Answer:
<DBC = 45
Step-by-step explanation:
The two angles add to 180
<ABC + <DBC = 180
135+ <DBC = 180
< DBC = 180-135
<DBC = 45
Not sure what more they want you say other than reflect over the line of y= x line
So change all the negative x number to positive and positive y to negative
Answer:
a) f(3) = -19
b) x = -2 (I assume you have to find x, but the question isn't very clear)
Step-by-step explanation:
a) f(3) = -4(3) - 7 = -12 - 7 = -19
b) Suppose f(x) = 1. Then 1 = -4x - 7, so -4x = 8, and thus x = -2
