Write a linear equation with a slope of 14 and y-intercept -12.
Answer:
y=14x-12
Step-by-step explanation:
in the standard format y=mx+b, m is the slope and b is the y-intercept, so this equation would be y=14x-12 since the slope is 14 and the y-intercept is -12.

Alex and Carmen both sell items at craft fairs. Alex earns $36 for 3 birdhouses, and Carmen earns $75 for 5 scarves. What is the unit rate that each person earns for their craft? How many birdhouses will Alex need to sell in order to make as much as Carmen does when she sells 12 scarves? How do you know?
Answer:
To be able to find the unit rate that each person earns for their craft, you have to divide the amount each person earns by the number of units:
Alex: $36/3=$12 per unit
Carmen: $75/5=$15 per unit
To find the amount of birdhouses that Alex will need to sell in order to make as much as Carmen does when she sells 12 scarves, first you have to determine the amount that Carmen earns when she sells 12 scarves:
$15*12=$180
Now, you need to divide $180 by the price per unit Alex earns to find the amount of birdhouses that he needs to sell:
$180/$12=15
This means that Alex needs to sell 15 birdhouses to make as much as Carmen does when she sells 12 scarves

you purchase 3 t-shirts and a booklet for 90$. the booklet cost 15. how much is each t-shirt? please help ! thank u
Answer:
each t-shirt was $25
Step-by-step explanation:
90 minus 15 = 75
75 divided by 3 equals 25
Answer:
25
Step-by-step explanation:
3t+15=90
3t=75
t=25
t represents the price for one t-shirt. 90 is the total amount and if the booklet is 15 dollars, altogether they equal 90. With this equation you are trying to isolate the variable (t), so subtract 15 because the opposite of 15 is -15. Then divide that by 3 because 3t is also 3 times t and the opposite of times is division.

2) 3 cm, 5 cm, 9 cm
3) 7 cm, 8 cm, 12cm
4) 24 cm, 21 cm, 33 cm
Answer: the correct answer is 3
The side lengths similar to triangle PQR are 24 cm, 28 cm, 44 cm
What are similar triangles?Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles.
Given that, a triangle PQR with side lengths 6 cm, 7 cm, and 11 cm.
Considering option 1) 24 cm, 28 cm, 44 cm
To see the similarity, we will check if the ratio of the corresponding sides are equal or not,
6/24 = 1/4
7/28 = 1/4
11/44 = 1/4
That means, 6/24 = 7/28 = 11/44 = 1/4
Since, the corresponding sides of these triangles are in equal ratios,
Hence, The side lengths similar to triangle PQR are 24 cm, 28 cm, 44 cm

Some people advise that in very cold weather , you should keep the gas tank in your car more than half full. Irene's car had 5.80 gallons in the 13- gallon tank on the coldest day of the year. Irene filled the tank with gas that cost 3.80 per gallon. How much did Irene spend on gas?
Answer:
22.04
Step-by-step explanation:
We are told in the question that:
Irene filled the tank with gas that cost 3.80 per gallon.
She has 5.80 gallons in her tank.
Hence:
1 gallon of gas = 3.80
5.80 gallons =

5.80gallons × 3.80/1 gallon
= 22.04
Therefore, Irene spent 22.04 on gas
if two lines lie in the same plane and are perpendicular to the same line they are perpendicular true or false?
If two lines lie in the same plane and are perpendicular to the same line they are perpendicular is TRUE.
What are parallel lines?Two lines in the same plane that are equally spaced apart and never cross each other are said to be parallel lines.
Parallel lines are those lines in which slopes are the same and the distance between them remains constant.
If a line is perpendicular to another then they will make 90 degrees at the intersection.
So if another line is also making 90 degrees it means both lines must be in the same direction so they will be parallel as given in the image below.
Hence "If two lines lie in the same plane and are perpendicular to the same line they are perpendicular is TRUE".

9. During training, a hurdler wants to raise the height of the hurdles from the high school standard of 39 inches to the
NCAA standard of 42 inches. His best race from last season included a clear over a 39-inch hurdle that was modeled by
h(t) = (-0.0251)(1-25), where t is time (in tenths of a second) after his lead leg left the track and h is the height (in feet).
If he runs as well as his best race last year, will this hurdler clear the new height? Why or why not
Answer:
Something doesn't make sense. The time when his height is 0 is time t=0 and t=25.
The vertex would be halfway in between at time t=(0+25)/2 = 12.5 seconds.
But plugging that in, we get a height of:
3.90625 inches
I think you must have a typo... let's try this equation instead:
h(t) = (-0.25t)(t - 25)
In that case, the maximum at h(12.5) is 39.0625 inches.
Answer:
No, the function for his height has him just barely clearing 39 inches. He can't clear 42 inches.

No, according to the function for his height, he only just clears 39 inches. He is unable to jump 42 inches.

Chad's baseball team is practicing hitting in the batting cages. The pitching machines pitch baseballs at a rate of 35 pitches in 5 minutes. Chad practiced hitting for 8 minutes.
How many baseballs were pitched to Chad in that time?
Answer:
56 baseball's
Step-by-step explanation:
The number of baseballs were pitched to Chad in 8 minutes is 56.
What is the unit rate?Unit rate can be defined as the ratio between two measurements with the second term as 1. It is considered to be different from a rate, in which a certain number of units of the first quantity is compared to one unit of the second quantity.
Given that, the pitching machines pitch baseballs at a rate of 35 pitches in 5 minutes.
Number of pitches hit in 1 minute = 35/5
= 7
Chad practiced hitting for 8 minutes.
So, the number of baseballs were pitched = 7×8
