$\bf (\stackrel{x_1}{4}~,~\stackrel{y_1}{\frac{1}{3}})
\qquad \qquad \qquad \qquad 
% slope = m
slope = m\implies \cfrac{3}{4}
\\\\\\
% point-slope intercept
\stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-\cfrac{1}{3}=\cfrac{3}{4}(x-4)\implies y-\cfrac{1}{3}=\cfrac{3}{4}x-3
\\\\\\
y=\cfrac{3}{4}x-3+\cfrac{1}{3}\implies y=\cfrac{3}{4}x-\cfrac{8}{3}$

Find the value of x in 19 and 20 so that f(x)=7

mafiozo [28]

Answer:

Part 19) x=5

Part 20) x=-3

Step-by-step explanation:

Problem 19) Find the value of x so that f(x)=7

step 1

Find the intersection point of the given line in the graph with the line y=7

The intersection point is (5,7)

see the attached figure

therefore

The x-coordinate of the intersection point is the value of x when f(x)=7

x=5

f(5)=7

Problem 20) Find the value of x so that f(x)=7

step 1

Find the intersection point of the given line in the graph with the line y=7

The intersection point is (-3,7)

see the attached figure

therefore

The x-coordinate of the intersection point is the value of x when f(x)=7

x=-3

f(-3)=7

Simplify the exponential problem<br> 7b^5/b^4

Norma-Jean [14]

Solution:

If the <u>numerator</u> and the <u>denominator</u> have like bases in exponents, then the <u>exponents</u> subtract.

$\frac{7b^5}{b^4} = 7b^5^{-4}$
=> $7b$

Thus, 7b is the simplified expression.
