write the equation of the line that passes through the point (0, 3) and is perpendicular.

please help me solve this :)

Answers

Answer 1

Answer:

y = 2x + 3

Step-by-step explanation:

to find the perpendicular line then you have to find the negative reciprocal which is 2 and to get that you flip the fraction and change the sign so

(-1/2) → 2/1 or 2

the y-intercept coordinate is (0, 3) so the y-intercept is 3

Answer 2

Slope of line in attachment=-1/2

Slope of the Perpendicular line=2

passes through (0,3)

If using the method of completing the square to solve the quadratic equation x^2-19x+23=0x

−19x+23=0, which number would have to be added to "complete the square"?

Answers

The number that needs tο be added tο cοmplete the square is 90.25.

What is the quadratic equatiοn?

In algebra, a quadratic equatiοn is any equatiοn that can be rearranged in standard fοrm as where x represents an unknοwn value, and a, b, and c represent knοwn numbers

Tο cοmplete the square fοr the quadratic equatiοn x² - 19x + 23 = 0, we need tο add a number that is equal tο half οf the cοefficient οf x (which is -19) squared.

Sο,

(-19/2)² = 90.25

Therefοre, we need tο add 90.25 tο bοth sides οf the equatiοn:

[tex]x^2 - 19x + 23 + 90.25 = 90.25[/tex]

Then we can rewrite the left side as a perfect square:

[tex](x - 9.5)^2 = 90.25[/tex]

Now we can take the square root of both sides to solve for x:

x - 9.5 = ±√(90.25)

x = 9.5 ± 9.5√(2)

Hence, the number that needs to be added to complete the square is 90.25.

Step-by-step explanation:

A medical delivery services charges $10 for a house call plus $0.50 per mile. The situation is represented by the equation c=0.5m+10 where m represents the number of miles the delivery is from the office and c represents the cost of the delivery. Calculate the total cost of a medical service delivery if the number of miles driven is 75.5 miles. Write your answer as an ordered pair (m,c).

Answers

Answer:

$47.75

Step-by-step explanation:

Where are given that the cost of medical service delivery is given by the expression

c=0.5m+10

m= the number of miles

when the number of miles is 75.5 mile we want to find the cost

put m=75.5 in the expression

c=0.5(75.5)+10

solving for c we have

c=37.75+10

c=47.75

Therefore the cost will be $47.75 for a distance of 75.5miles

Dana helped her dad build a sandbox for her younger sister. The sandbox is shaped like a rectangular prism that is 4 1 2 feet long and 4 feet wide. Dana used bags of sand to fill the sandbox 1 2 of a foot deep. Each bag contains 1 2 of a cubic foot of sand. How many bags of sand did Dana use?

Answers

The number of bags of sand needed to fill the sandbox is 18 bags

How to find volume of a rectangular prism

Length = 4 1/2 ftWidth = 4 ftHeight = 1/2 ftQuantity of each bag of sand = 1/2 ft³

Volume = L × W × H

= 4 1/2 × 4 × 1/2

= 4.5 × 4 × 0.5

= 9 ft³

Number of bags of sand needed to fill the sandbox = volume of the sandbox ÷ quantity of each bag

= 9 ft³ ÷ 1/2 fr³

= 9 × 2/1

= 18 bags

what is the equation of a line that is perpendicular to -x+7y=42 and goes through (-2,-1) in slope intercept form

Answers

Answer:

y = -7x - 15

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes

Given line

- x + 7y = 42

In slope-intercept form it is

- x + 7y = 427y = x + 42y = 1/7x + 6

Perpendicular line has slope - 1/(1/7) = - 7 and its equation is:

y = - 7x + b

Finding b using the point (-2, -1)

-1 = -7(-2) + b-1 = 14 + bb = -1 - 14b = -15

So the line is

y = -7x - 15
