Answer:
(-5,-14)
Step-by-step explanation:
To find the solution of the system of two equations

equate right sides of these two equations:

Rewrite terms with x into the left side and without x into the right side:
![4x-2x=-4-6\\ \\2x=-10\ [\text{divide by 2}]\\ \\x=-5](https://tex.z-dn.net/?f=4x-2x%3D-4-6%5C%5C%20%5C%5C2x%3D-10%5C%20%5B%5Ctext%7Bdivide%20by%202%7D%5D%5C%5C%20%5C%5Cx%3D-5)
Substitute x=-5 into the first equation:

The solution is (-5,-14)
% of 15 in 500= (15÷500)×100
= 0.03×100
= 3 %
It should be 7.615773106
But rounded should be 7.6
Answer:
To shift right 5 units equation needs to be: y=0.5(x-<u>5</u>)^2
To shift left 5 units equations needs to be y=0.5(x+<u>5</u>)^2
To shift up 5 units equation need to be y=0.5x^2 +<u>5</u>
To shift down 5 units equation need to be y=0.5x^2 -<u>5</u>
For the question with 8 units just replace all the <u>5</u> with 8.
Answer:
b=24
Step-by-step explanation:
VT^2 + (2b)^2 = 67^2
VT^2 + (b+24)^2 = 67^2
-> (2b)^2 = (b+24)^2
-> 2b = b+ 24
-> b = 24
