If it’s a horizontal line, we focus on the y-coordinates.

(-7,5)

-7 is a x-coordinate
5 is a y-coordinate


The answer is y = 5

Please help fast i will give you the most Brainly <br><br><br> what would n = 3(n+7)=48
neonofarm [45]

Answer:

n = 9

Step-by-step explanation:

3(n+7)=48

distribute

3n +21 = 48

subtract 21 from each side

3n = 48-21

3n = 27

divide by 3

3n/3 = 27/3

n = 9

The diameter of a circle is 16 kilometers. Find the area of the circle.
Elden [556K]

The diameter of a circle is 16 kilometers. Then the area of the circle is 201.062 \mathrm{km}^{2}

<u>Solution:</u>

Given that , the diameter of a circle is 16 kilometers  

We have to find the area of the circle .

Radius is half of diameter.

\begin{array}{l}{\text { diameter }=2 \times \text { radius } \rightarrow \text { radius }=\frac{\text {diameter}}{2}} \\\\ {\rightarrow \text { radius }=\frac{16}{2} \rightarrow \text { radius }=8 \text { kilometers. }}\end{array}

<em><u>The area of circle is given as:</u></em>

\begin{array}{l}{\text { area of a circle }=\pi \times r^2 \\ {\text { Area of a circle }=\pi \times 8^{2}=\pi \times 64=64 \times 3.14=201.062}\end{array}

Hence, the area of the circle is 201.062 km^2

Can anyone help me solve 23, 24?
zimovet [89]

Answer:

Problem 23) y=3x+6

Problem 24) y=-\frac{1}{3}x-5

Step-by-step explanation:

step 1

Find the slope of the given line

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we have

A(0,2)\ B(3,1)

Substitute the values

m=\frac{1-2}{3-0}

m=-\frac{1}{3}

step 2

Problem 23

we know that

If two lines are perpendicular then the product of its slopes is equal to minus 1

so

m1*m2=-1

Find the slope of the line

we have

m1=-\frac{1}{3}

substitute in the equation and solve for m2

(-\frac{1}{3})*m2=-1

m2=3

with the slope m2 and the point (0,6) find the equation of the line

Remember that

The equation of the line in slope intercept form is equal to

y=mx+b

we have

m=3

b=6 -----> the given point is the y-intercept

substitute

y=3x+6

step 3

Problem 24

we know that

If two lines are parallel, then its slopes are the same

so

with the slope m1 and the point (0,-5) find the equation of the line

The equation of the line in slope intercept form is equal to

y=mx+b

we have

m=-\frac{1}{3}

b=-5 -----> the given point is the y-intercept

substitute

y=-\frac{1}{3}x-5
