Step-by-step explanation:
so fill in 88 where the x is so
y = 0.9 (88) - 1
y = 78.2
46
Step-by-step explanation:
all angles must add to 180
32+102= 134
180-134= 46
correct me if im wrong:)
Answer:
Step-by-step explanation:
The secants form a proportion where the full length of the secant is the denominator of a fraction where the numerator is the external part of the secant.
7/(x + 7) = 6/(15 + 6) Cross Multiply after combining
7 / (x + 7) = 6/(21)
6 * (x + 7) = 7 * 21 Remove the brackets
6x + 42 = 147 Subtract 42
6x = 147 - 42
6x = 105 Divide by 6
x = 17.5
I think I've done this correctly. If you find an error, please let me know and I'll open it for editing.
Answer:
C and A
Step-by-step explanation:
expand the things in parentheses so for C
1/2(x + 16) = 1/2(x) + 1/2(16) = 1/2 x + 8
same process for A
Answer:
2.
Domain: all real values of x
Range: f(x)》-4
3.
Domain: all real values except x = 0
Range: All real values except f(x) = 0
Step-by-step explanation:
2.
Domain: all real values of x
Range: f(x)》-4
Because this is a concave up quadratic with a minimum turning point at (0,-4)
3.
Domain: all real values except x = 0
Range: All real values except f(x) = 0
Since x is in the denominator, it can't be 0
For f(x) = 0, x has to be infinity
