Answer:

When slope and one point are known follow instructions on this page:

http://www.1728.org/distance.htm

Calculate "b" from this equation:

b = y -mx where "m" is the slope

We'll use the point given (-2, -1) for "x" and "y"

b = -1 -(8/7) * -2

b = -1 + 16/7

b = 9/7

then we enter "b" and the slope into this equation

y = 8/7x +9/7

y = 1.142857 x + 1.2857142857

Consider f(x)=x+7 and g(x)=x^2-1 find (g of f)(x)

finlep [7]

Answer:

g(f(x))=x^2 + 14x + 48

Step-by-step explanation:

you insert (x+7) into every x in the g(x) equation, so g(x)=(x+7)^2 - 1. then you simplify it by doing (x+7)(x+7) which gets you x^2 + 14x + 49. then you subtract the 1 from the equation to get g(f(x))=x^2 + 14x + 48.

Mike scored a 125 at a semi-final dividing competition season. He scored 95 at this final season. What is the percentage decreas

IrinaK [193]

Answer:

There was a 24% decrease

Step-by-step explanation:

Percentage decrease = (final season's score - semi-final score) / semi final score x 100

$\frac{95-125}{125}$ ×100

$\frac{-30}{125}$ × 100 = -24%
