Answer:
Step-by-step explanation:
Just multiply the first equation by -1 and then add them together to find x. Should look something like
-2x - y = -7
5x + y = 9
--------------------
3x + 0 = 2
x = 2/3
Now back substitute using either equation to find y. I'll use the first:
2(2/3) + y = 7
4/3 + y = 7
y = 7 - 4/3 = 21/3 - 4/3 = 17/3
Answer:
x=2/3
y=17/3
The value of k is 735 feet.
<h3>What is a scale drawing? </h3>
A scale drawing is a smaller image in terms of dimensions of a bigger image / building / object.
The scale of the drawing = original dimensions / dimensions of the scale drawing
<h3>What is the value of k? </h3>
The value of k = height of the antenna / length of the antenna in the model
750 / 1..02 = 735 feet

Answer: -2x²-11x-35
Step-by-step explanation:
-2(p+4)²-3+5p
-2(x²+8x+16)-3+5x
-2x²-11x-35
I got x = -1507/14 and the altérnate form of that is x = -107 9/14
