The first one is D because c represents the x and b represents the y. For the second one:
38(2) = 76
180-76 (this is the sum of the unknown measures)
104/2 (finds the measure of each angle)
52
I am unsure of the final one though.
Hope this helps!
3(5^x) is an exponential function.and which rise very fast
y = 127 - 2x is a line Which decrease wçith a 2 slope f(0) = 127
3.5^2 = 75 and 3.5^3 = 375
I guess the intersection will be between 2and 3
lets put both the functions in a graph calculator
window:
x between 2 and 3
y between 75 and 127
I have an intersection between 2 and 3
use the "table" of the calculator
we can see that the intersection is between 2.3 and 2.4
try again
range:
start:2.3
end 2.4
intersection is in [2.3;2.31]
lets say it's 2.305
to translate coordinates in this manner, for each point perform the following:
add 5 to the original x coordinate
add 2 to the original y coordinate
option a is the answer
Answer:
=−6
Step-by-step explanation:
The answer is D. 76. This is because if STR is 28 degrees, and angle STU is on a straight line, all we have to do is subtract 180-28, then divide by 2.
