Step 1: multiple the second equation by 2 so that you get -1/4 for the coefficient of y, the same as in equation 1
equation 2 multiply by 2: 1/4 x - 1/4 y=38 ..........name this equation 3
subtract equation 1 from equation 3: (1/4 x -1/2 x)=38-10
-1/4 x = 28
x=-112
plug in x=-112 in any of the equation, you will get y=-264
so the answer is A
Answer:
Yes, this graph is absolutely right for the function y = 
.
Step-by-step explanation:
firstly we will calculate amplitude, period, phase shift, and vertical shift.
Use the standard form 
to calculate the values of amplitude, period, phase shift, vertical shift.
here a = 2
b = 2
c = 0
d = -3
Amplitude = |a| = 2
period = 
= 
= 
phase shift = 
= 0
and vertical shift = d = -3
so, by using this information, if we plot the graph then the graph obtained will be same as the given graph.

Answer: 25t+45m
Step-by-step explanation:
Really simple because if they traveled 25mi/h for t hours, that makes it 25t miles. They traveled 45mi/h for m hours so it's 45m. If you add them together, 25t+45m.

Answer:
{−1008,−504,−252,−126,…}
Step-by-step explanation:
-504÷(-1 008)=0.5
(-252)÷(-504)=0.5
(-126)÷(-252)=0.5
In this sequence ,we multiply by 0.5 each time to get the next term
then it’s a geometric sequence.
