Y= -6 - 26 because the equation y + 2 = -6(x + 4) you use distributive property so it is now y + 2 = -6x - 24 now take the 2 and subtract it from -24 giving -26 giving the answer y = -6 - 26

I probably said that in a really confusing way but I think I’m correct

Math help Please!!!!

Part A. What is the slope of a line that is perpendicular to a line whose equation is −2y=3x+7?

Rewrite the equation  −2y=3x+7 in the form y=-\dfrac{3}{2}x-\dfrac{7}{2}. Here the slope of the given line is  m_1=-\dfrac{3}{2}. If m_2 is the slope of perpendicular line, then

m_1\cdot m_2=-1,\\ \\m_2=-\dfrac{1}{m_1}=\dfrac{2}{3}.

Answer 1: \dfrac{2}{3}

Part B. The slope of the line y=−2x+3 is -2. Since -\dfrac{3}{2}\neq -2\quad \text{and}\quad \dfrac{2}{3}\neq -2, then lines from part A are not parallel to line a.

Since -2\cdot \left(-\dfrac{3}{2}\right)=3\neq -1\quad \text{and}\quad -2\cdot \dfrac{2}{3}=-\dfrac{4}{3}\neq -1, both lines are not perpendicular to line a.

Answer 2: Neither parallel nor perpendicular to line a

Part C. The line parallel to the line 2x+5y=10 has the equation 2x+5y=b. This line passes through the point (5,-4), then

2·5+5·(-4)=b,

10-20=b,

b=-10.

Answer 3: 2x+5y=-10.

Part D. The slope of the line y=\dfrac{x}{4}+5 is \dfrac{1}{4}. Then the slope of perpendicular line is -4 and the equation of the perpendicular line is y=-4x+b. This line passes through the point (2,7), then

7=-4·2+b,

b=7+8,

b=15.

Answer 4: y=-4x+15.

Part E. Consider vectors \vec{p}_1=(-c-0,0-(-d))=(-c,d)\quad \text{and}\quad \vec{p}_2=(0-b,a-0)=(-b,a). These vectors are collinear, then

\dfrac{-c}{-b}=\dfrac{d}{a},\quad \text{or}\quad -\dfrac{a}{b}=-\dfrac{d}{c}.

Answer 5: -\dfrac{a}{b}=-\dfrac{d}{c}.

A linear function has a slope of 2 and passes through the point (0,6). What is the equation of the line?
pychu [463]
A linear function means you’re working with a line. Lines can be stated in slope-intercept form: y=mx+b.

To make it a linear function, you simply replace “y” with “f(x)” notation: f(x) = mx + b

The information you gave told you m=2 and b=6, since (0,b) is the y-intercept.

Putting that all together you have:
f(x) = 2x + 6

Delicious77 [7]

<u><em>Answer:</em></u>

Elena's running speed is 5 miles/hour

<u><em>Explanation:</em></u>

The speed is defined as the covered distance per unit time

<u>In the problem, we have:</u>

The distance covered is the length (circumference) of the circular track which is given as \frac{1}{4} of a mile.

We are also given that she completes each lap (she completes \frac{1}{4} of a mile) in \frac{1}{20} of an hour

To get her speed, we will divide the distance covered by the time taken to cover this distance

<u>This is done as follows:</u>

speed = \frac{\frac{1}{4} }{\frac{1}{20} } = 5 miles/hour

<u>This means that:</u>

Elena can run 5 miles each hour

Hope this helps :)
