Step-by-step explanation:
y=7x-16 we substitute in y=x^2-10x+14
7x-16=x^2-10x+14
x^2-10x-7x=-30
×^2-17x+30=0
x=2
×=15
Answer:
3 and -10
Step-by-step explanation:
3+-10=
3-10=-7
Answer:

Step-by-step explanation:
Use the right triangle formula c^2=a^2+b^2
C is the number of the hypothenuse while b and c are the 2 others.
16^2=7^2+a^2
256=49+a^2
now solve for the equation.
a^2=207
now take the square root of both.
a=![\sqrt[2]{207}](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B207%7D)
