(m-21) (m+1)there I thinks it's right unless I messed up my work
Answer:
[tex](m - 21)(m + 1)[/tex]
Step-by-step explanation:
[tex]m^{2} - 20m - 21[/tex]
Lets split the middle term.
[tex]=> m^{2} - 21m + m - 21[/tex]
[tex]=> m(m - 21) + 1(m - 21)[/tex]
[tex]=> (m - 21)(m + 1)[/tex]
Work out the percentage change when a price of £20 is increased to £22.
Answer:
10% increase
Step-by-step explanation:
To find the percent change, divide the difference between the 2 prices by the original price:
2/20
= 0.1
So, the percent change was 10%

x/4+2=10
what is x in equation?
Answer:
x = 32
Step-by-step explanation:
x/4 + 2 = 10
subtract 2 on both sides
x/4 + 2 - 2 = 10 - 2
x/4 = 8
Multiply 4 on both sides
x/4 * 4 = 8 * 4
x = 32
__________________________________________________________
Check:
32/4 + 2 = 10
8 + 2 = 10
10 = 10 CORRECT

Determine K such that 2/3, k, 5/8,K are consecutive terms of an ap
Answer:
k = 16/33
Step-by-step explanation:
Determine k so that 2/3,k and 5/8k are the three consecutive terms of an a.p
k - 2/3 = 5/8k - k
3k-2/3 = 5k-8k/8
Cross product
(3k-2)(8) = (3)(5k-8k)
24k - 16 = 15k - 24k
24k - 16 = -9k
24k + 9k = 16
33k = 16
k = 16/33
The audio store normally sells a pair of speakers for $280. They are on sale this weekend for $224. What is the percent of decrease in price?
Answer: 20%
Explanation:
1. Turn it into a fraction (224/280)
2. Divide the numerator (224) by the denominator (280). (224÷280=0.8)
3. Subtract 1 by 0.8 (or 100% by 80%) that should give you the answer 0.2 (20%)
Checking work:
280x0.2=56
280-56=224
Joshua is training for a race. The ratio of the number of minutes he runs to the number of miles he runs is 24 to 3. He plans to run 10 miles. How many minutes will it take him?
Answer:
Time taken to cover 10 miles = 80 minutes
Step-by-step explanation:
Given:
Ratio [Number of minutes : Number of miles runs] = 24:3
Find:
Time taken to cover 10 miles
Computation:
Number of minutes/Number of miles runs = Time taken to cover 10 miles / 10
24/3 = Time taken to cover 10 miles / 10
Time taken to cover 10 miles = 80 minutes

Is it possible for a right triangle with a leg that is 12 inches long and a hypotenuse that is 37 inches long to be congruent to a right triangle with a leg that is 35 inches long and a hypotenuse that is 37 inches long? Complete the explanation.
Yes
. Let the remaining leg of the first triangle have a length of x inches. Then by the Pythagorean Theorem, x2 + 122 = 372. So, x2 + 144 = 1,369, x2 = 1,225, and x =
. Therefore, the hypotenuse and a leg of the first right triangle are congruent to the hypotenuse and a leg of the second right triangle, so the triangles
are
congruent by the HL Triangle Congruence Theorem.

I NEED HELP ASAP PLEASE (will give brainliest)
Answer: ↓↓
Step-by-step explanation:
∠ABF and m∠60° are complementary since they form a right angle.
∠ABF + 60 = 90
∠ABF = 30°
∠ABF and ∠CBD are vertical angles so they're congruent.
∠CBD ≅ ∠ABF
∠CBD ≅ 30
∠CBD = 30°
∠ABC and ∠CBD are linear pair so they're supplementary.
∠ABC + ∠CBD = 180°
∠ABC + 30 = 180
∠ABC = 150

Papa John's sold 236 pizzas last night. The manager wants to give the workers a prize if they can increase the number of pizzas sold by 24%. How many pizzas do they need to sell to get the prize? (Remember if there is a decimal to round up to the next whole number so 13.2 would become 14)
Answer:
You need to increase the amount of pizza sold by 24%, you can do it one of two ways:
236*0.24 = 56.64 and then do 236 + 56.64 = 292.64
(this way you find out what 24% of 236 is and then add it to 236 to get an increase of 24% )
or you can do this:
236 *1.24 = 292.64
(this way you're finding out what 124% of 236 is. I find this way easier because there's less steps. it works because you're still finding out what 24% is, you're just keeping the 236 there)
either way they need to sell 293 pizza's to get the prize

Find EF in the trapezoid.
How can I solve for this?
Answer:
Ef=52
Step-by-step explanation:
By the mids segment theorem if a line sgement has endpoints on the midpoints of 2 sides of a triangle then it is half the size of the third side.
That means
2(4x+8)=9x-5
8x+16=9x+5
11=x
Then plug it back in to EF
4(11)+8
44+8
52

Answer:
-1
Step-by-step explanation
Raising -1 to an odd power gives us -1, while raising -1 to an even power gives us (positive) 1. Because 2009 is odd, the answer is -1. The other answer choices are there to confuse you.

What are the x- and y-intercepts of the following Standard Form Equation:
- 2x + 5y = 0
Answer:
X-Intercept: [tex]x=-\frac{5}{2}y[/tex]
Y-Intercept: [tex]y=-\frac{2}{5}x[/tex]
Step-by-step explanation:
X-Intercept-
2x+5y=0 - Move the variable to the right-hand side and change its sign
2x=-5y - Divide both side of the equation by 2
x=-5/27 - Write the solution x in parametric form
x=-5/2y, y∈R
Y-Intercept-
2x+5y=0 - Move the variable to the right hand side and change its sign
5y=-2x Divide both sides of the equation by 5
y=-2/5x Write the solution y in parametric form
y=-2/5x, x∈R
Take your time with this. What are the answers for C and D? Will mark Brainliest.
Answer:
Step-by-step explanation:
Part C- y=20x+600
Part D- To part D find the equations for all the cities.
Everett- y=15x+550
Chelsea- y=20x+600
Revere- y=50x+300
Since 2030 is 14 years away from 2016 x will equal 14.
Plug in 14 to each of the equations. Whichever has the highest result will be the answer.
Everett- y=15(14)+550 -----> y=760
Chelsea- y=20(14)+600 -----> y=880
Revere- y=50(14)+300 -----> y=1000
Revere will have the most chromebooks.

This is the same as saying the set of all real numbers.
There are no restrictions to put on the domain, so there are no values to avoid. This is because there are gaps, jumps, or holes in the graph. It's one continuous single curve.
This curve stretches forever to the left and right. As it goes left, it moves up (rises to the left). As it moves right, it goes downhill (it falls to the right). Saying "rises to the left and falls to the right" is an informal way to describe the end behavior. The actual specific end behavior doesn't matter. What matters is both left and right sides go on forever.
A domain of the set of all real numbers means we can plug in any real number for x, and get some output for y, which is part of the range.
One way we can describe the set of all real numbers in terms of an inequality is to write [tex]-\infty < x < \infty[/tex] meaning that x is between negative and positive infinity, ie x is anything you want. The inequality [tex]-\infty < x < \infty[/tex] converts to the interval notation [tex](-\infty, \infty)[/tex]. Interval notation is a compact way of writing compound inequalities.
