Which of the following coordinate planes shows the graph of the function y-3=-2(x+2)?
Answer:
-5=x
Step-by-step explanation:
3=-2 (x+2)
-2 (x+2) = -2x-4
3=-2x-4
-4 from 3 and -4
= -7=-2x
do the opposite "-2 to +2 "
=-5=x

You need to buy 12 tickets to a weekend concert festival but have two options for where to purchase them. Concert Specialties sells a pack of 3 tickets for $75 and We 'R' Entertainment sells a pack of 4 tickets for $108. Which ticket outlet should you buy the 12 tickets from to spend the least amount of money? Explain your reasoning.
Answer:
Concert Specialties is the better buy
Step-by-step explanation:
In order to determine which of the two deals is the better buy, we first need to find out how many of each pack we would need to get the needed 12 tickets. Once we have this value we multiply it by the dollar amount of each pack and compare the totals like so...
Concert Specialties => pack of 3 * 4 = 12 tickets => 4 * 75 = $300
We 'R' Entertainment => pack of 4 * 3 = 12 tickets => 3 * 108 = $324
Therefore, we can now see that the Concert Specialties is the better buy since you are getting the 12 tickets for $24 less than We 'R' Entertainment

Translate five times the sum of a number and three into a mathematical expression
Answer:
5(x-3)
Step-by-step explanation:
The word "SUM" means the answer to an "ADDITION".
"SUM" is always used with the word "AND" to indicate which numbers are being added.
The SUM of a number AND -3 is written as:
( x + ( − 3 ) ), or ( x -3 )
(where we have chosen the number to be x .)
But we want FIVE of those sums; this means:
5 ( x − 3 )

If a coffee bar sells on average 12 ounces of coffee every three minutes during the busy morning hours, how many gallons of coffee do they sell in 4 hours?
Answer:
7.5 gallons
Step-by-step explanation:
divide 12 by 3 to get oz per minute. 4
do 60 × 4 to get total minutes 240
4×240=960
put 960 oz into gallons and get 7.5

Write the equation of a line that is perpendicular to y=2/7x +9 and that passes through the point (4,-6).
Answer:
[tex]y=-\frac{7}{2}x+8[/tex]
Step-by-step explanation:
Given the equation
[tex]y\:=\:\frac{2}{7}x+9[/tex]
comparing the equation with the slope-intercept form
[tex]y =mx+b[/tex]
Here,
m is the slope y is the interceptso the slope of the line is 2/7
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so
the slope of the perpendicular line will be: -7/2
Therefore, the point-slope form of the equation of the perpendicular line that goes through (4,-6) is:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-\left(-6\right)=\frac{-7}{2}\left(x-4\right)[/tex]
[tex]y+6=\frac{-7}{2}\left(x-4\right)[/tex]
[tex]y+6-6=\frac{-7}{2}\left(x-4\right)-6[/tex]
[tex]y=-\frac{7}{2}x+8[/tex]

Answer:
-2
Step-by-step explanation:
its -2 cuz to find the slope the equation is the second y - the first y over the second x - the first x so -5 - 5 is 10 over 3 - -2 is 5 so it would be -10/5 which simplifies to -2

x (5b - 2) = 2b +3
Answer:
x = [tex]\frac{2b+3}{5b-2}[/tex]
Step-by-step explanation:
Given
x(5b - 2) = 2b + 3 ← isolate x by dividing both sides by (5b - 2)
x = [tex]\frac{2b+3}{5b-2}[/tex]

Lucia is 5.5 feet tall. She is standing on the roof of a building that is 80 feet tall. She spots a fountain at ground level that she knows to be 122 feet away from the base of the building. What is the measure of the angle of depression formed by Lucia's horizontal line of sight and her line of sight to the fountain? Round your answer to the nearest degree.
Answer:
125°
Step-by-step explanation:
So we know that the total height is 85.5 (building height plus Lucia's height) and that the distance between Lucia and the fountain is 122ft away. As seen in the badly drawn picture below, the question asks us to solve for x, we can do this by first solving for y by using tangent to calculate its value which is the following
tan(y) = opposite / adjacent
tan(y) = 122 / 85.5
tan(y) = 1.4269
y = [tex]tan^{-1}[/tex](1.4269)
y = 54.97
Now that we have the value of y and we know that a straight line has a degree of 180, we can simply subtract the degree of y from 180 to get the degree of x
180 - 54.97 = 125.03
Answer:
about 35°
Step-by-step explanation:
tan^-1(85.5/122)
35.02352736°
=35°
Joanna bought a car and after 5 years of payments, she paid $6,250. The initial loan for the car was $5,000. What was the interest rate on Joanna's loan for the 5 years?
HELP ME PLS
Answer:
5%
Step-by-step explanation:
6,250-5000
1,250
divide that by 5
you get 250
250/5000= 0.05
multiply that by 100 to get the percentage (interest rate)
so the answer is a 5% interest rate

Answer:
y= 3x-1
Step-by-step explanation:
Use two points from the line to find slope. I'm using (1,2) and (2,5)
Put these values into slope formula and get 5-2/2-1 which simplifies to 3. So slope is 3.
Next, for the y-intercept. If you look closely, the line intercepts the y-axis at (0,-1), so our y-intercept is -1.
Put the equation together to get y=3x-1
