Answer:
a = -2
Step-by-step explanation:
(x-2) (x+b) = x² + (b-2) x - 2b = x² + 3x + 5a
b-2 = 3
b = 5
5a = - 2b = - 10
a = -2

A Store recudes the price of a jacket by 40%. The sale price of the jacket is $30.
A. What percent of the original price is the sale's price
B. What was the original price of the jacket.
Answer:
A. 60%
B. The original price is $50
Step-by-step explanation:
A. 60%
Sales Price = 100 - 40 = 60%
The sales price is $30.00
Therefore 60% is equal to $30.00
60% = $30
1% = 30 ÷ 60 = $0.50
100% = 5 x 100 = $50
B. The original price is $50
Percentage of the original price = 30/50 x 100 = 60%
The ratio of boys to girls is 5:1 if there are 60 more boys than girls workout how many people there are in total
Answer: 80
Step-by-step explanation:
Let the number of girls be x
Therefore, the number of boys will be: = x + 60
The ratio of boys to girls is 5:1. Using this and equating to the number of bits and girls will be:
5/1 = x + 60/ x
Cross multiply
5x = x + 60
5x - x = 60
4x = 60
x = 60/4
x = 15
Number of girls = 15
Therefore boys will be: = x + 60 = 15 + 60 = 75.
Total number of people = 15 + 75 = 80
A hospital ordered 9 boxes of cotton swabs. There were 300 cotton swabs in each box. How many cotton swabs did the hospital order in all?
Answer:
2,700 Cotton Swabs
Step-by-step explanation:
Since 300 cotton Swabs were in each box you would multiple 300 by 9 since the hospital ordered 9 boxes, this will get you 2,700 cotton swabs.
If a polynomial function f(x) has roots 3 and StartRoot 7 EndRoot, what must also be a root of f(x)?
Answer:
–√(7) must also be a root of f(x)
Step-by-step explanation:
Given that the roots of an equation is 3 and √(7). This means that x = 3 or √(7). Therefore, the function is definitely going to be:
f(x) = (x – 3)(x² – 7)
This is because we are dealing with √(7) and what brought about √(7) was x² = 7.
If this is the case, we know that x² = 7 will give
x = ±√(7)
Hence, our roots are x = 3 or √(7) or –√(7). Therefore, –√(7) must also be a root of f(x).

A

To send a letter to Country Q, the postal service charges: $0.79 for the first ounce and $0.55 for each additional ounce. How much would it cost to send a letter that weighs 8 ounces?
Answer: $4.64
Step-by-step explanation:
The first ounce is charged at $0.79 and then every additional ounce is $0.55.
There are 8 ounces to send.
The cost will therefore be:
= Cost of first ounce + Cost of 7 additional ounces
= 0.79 + (0.55 * 7)
= 0.79 + 3.85
= $4.64

The ratio of ounces of blueberries to ounces of yogurt is 2 to 5.How many ounces of yogurt would be needed for a smoothie with 10 ounces of blueberries?
Answer: 25 ounces of yogurt
Step-by-step explanation:
Blueberries to Yogurt
2 to 5
10 to ?
The original ratio is 2 ounces of blueberries and its now 10 ounces. We got ten ounces by multiplying 2 by 5. To get the ounces of yogurt, you have to also multiply by 5.
5 x 5 = 25
So the ratio of blueberries to yogurt is now, 10 to 25.

Hank decided to invest money into a retirement fund. If the average investment return is 12% and Hank invests the yearly maximum of $6,000 how much interest will that initial investment be worth in 20 years?
Answer:
$14400
Step-by-step explanation:
Using the formula for calculating the simple interest expressed as;
SI = Principal * Rate * Time/100
Given
Principal = $6000
Rate = 12%
Time = 20 years
Substitute into the formula;
SI = 6000 * 12 * 20/100
SI = 60*12*20
SI = 14,400
hence the interest worth after 20years will be $14400
solve 11x-22=(2)5x+4

We are given radius, r = 7 inches
We know that :
Circumference = 2πr
⟹ Circumference = 2π × 7 inches
⟹ Circumference = 14π inches
Hence, circumference of circle is 14π inches.

Personal Statement
Please include a personal statement about why you are applying and what you feel you can contribute to the program. Your statement should be a minimum of 500 words and include the following information: Why would you like to attend this Oxbridge program? Please tell us about your academic and extracurricular interests. Be sure to include your current, unweighted grade point average (GPA) or your school's equivalent. What interests you about the Major and/or Minor/Workshop courses you intend to pursue? What do you feel you will contribute to the program? Feel free to share any additional details that you feel may help our Admissions Team understand why you are a good fit for this program. so can someone help me cause I'm not sure how to write this on a way that is convincing
Why I would like to attend this Oxbridge program is simple, really however let me answer other things first. I enjoy the Workshop and stained glass classes I have been exposed too. My GPA is 3.7 in my current school. But it has been going through my family and I want to make them proud, It is something I have been interested in and enjoyed learning about. However your program is the perfect to extend my knowledge and help me expand my horizons. In my future I see myself doing this. This school hands down has one of the best programs out their.
I see that this is a competative program and that you expect the best, and I am the best. I play hard but work way harder.
Max is trying to prove to his friend that two reflections, one across the x-axis and another across the y-axis, will not result in a reflection across the line y = x for a pre-image in quadrant II. His friend Josiah is trying to prove that a reflection across the x-axis followed by a reflection across the y-axis will result in a reflection across the line y = x for a pre-image in quadrant II. Which student is correct, and which statements below will help him prove his conjecture? Check all that apply. Max is correct. O Josiah is correct. Taking the result from the first reflection (x, y) and applying the second mapping rule will result in (-X, -y), not (y x), which reflecting across the line y = x should give. If one reflects a figure first across the x-axis from quadrant II then reflects across the y-axis from quadrant II, the image will end up in quadrant IV. O A figure that is reflected from quadrant II to quadrant IV across the line y = x will have the coordinates of (-y).
Answer:
Max is correct
Taking the result from the first reflection (x, –y) and applying the second mapping rule will result in (–x, –y), not (y, x), which reflecting across the line y = x should give.
If one reflects a figure first across the x-axis from quadrant II then reflects across the y-axis from quadrant III, the image will end up in quadrant IV.
Step-by-step explanation

Max is correct If one reflects a figure first across the x-axis from quadrant II and then reflects across the y-axis from quadrant III, the image will end up in quadrant IV.
What is coordinate geometry?
A coordinate plane is a 2D plane which is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.
Taking the result from the first reflection (x, –y) and applying the second mapping rule will result in (–x, –y), not (y, x), which reflecting across the line y = x should give.
If one reflects a figure first across the x-axis from quadrant II and then reflects across the y-axis from quadrant III, the image will end up in quadrant IV.
Therefore Max is correct If one reflects a figure first across the x-axis from quadrant II and then reflects across the y-axis from quadrant III, the image will end up in quadrant IV.

Answer:
144 [tex]cm^{2}[/tex]
Step-by-step explanation:
All you need to do is find the area of all the shapes and then add them together
Front triangle:
A = b * h ÷ 2
A = 8 * 6 ÷ 2
A = 48 ÷ 2
A = 24
The front and back triangle area will be the same so the back triangle will also be 24.
Top rectangle:
A = b * h
A = 10 * 4
A = 40
Back rectangle:
A = b * h
A = 6 * 4
A = 24
Bottom Rectangle:
A = b * h
A = 8 * 4
A = 32
Now that we have all the areas for the shape, all we need to do is add them all up to find the surface area for the whole shape.
24 + 24 + 40 + 24 + 32 = 144

what is 1 3/4 + 1/6 + ? = 7 1/2
Answer:
x = 5 7/12
Step-by-step explanation:
let x = ?
7/4 + 1/6 + x = 15/2
multiply the equation by 12 to eliminate fractions
12([tex]\frac{7}{4}[/tex]) + 12([tex]\frac{1}{6}[/tex]) +12x = 12([tex]\frac{15}{2}[/tex])
21 + 2 + 12x = 90
23 + 12x = 90
12x = 90 - 23
12x = 67
x = 67/12 = 5 7/12
