Answer:

(2x-7)+ (-7)

Step-by-step explanation:

sum: 2x-7 + -2x

-7

an equivalent expression would be 3x-7-3x, or anything else that simplifies to -7

Answer: true

Step-by-step explanation:

Answer:

$200. had to edit, read the question wrong originally

=======================================================

Work Shown:

If you save 64%, then you still have to pay the remaining 100% - 64% = 36%

x = original price in dollars

sale price = 36% of x = 0.36*x = 72

0.36*x = 72

x = 72/0.36

x = 200

The original price is $200

discount = 64% of 200 = 0.64*200 = 128

You save $128

The amount you pay is 200-128 = 72 dollars, which matches with the given sale price.

Answer:

y = -x + 7

Step-by-step explanation:

y = x + 4   slope: 1

slope of perpendicular line: -1

for (2,5)   y interception (b) = y - mx = 5 - (-1)*2 = 7

equation: y = -x + 7

check: -x+7 = -2+7 =5

please mark me as brainliest, i'd really appreciate it!<3

Answer: She would have $315

Because there are 7 days in a week so you multiply 22.50 by 7 and you get 157.5, Then because she does it for two weeks you multiply 157.5 by 2 and you get 315

Hope this helps

Answer:

By subtracting

Answer:

15.8

Step-by-step explanation:

So top of 15ft + 0.8 ft = 15.8 ft

meaning the strings needs tobe 15.8 ft long

Answer:

77 girls

Step-by-step explanation:

becasue 49 divided by 7 is 7. so you just multiply 11 by 7. ANd that will get you 77

[tex]\boxed{\boxed{\pink{\sf \leadsto Hence \ the \ Inverse \ of \ the \ given \ function \ is \ x^2+2x-4 .}}}[/tex]

A function is given to us , and we need to find its inverse. So the function is ,

[tex]\bf\implies f(x) = \sqrt{x + 5 } - 1 [/tex]

So , firstly replace x with y in the given function and then solve for y to get its inverse . Taking the given function ,

[tex]\bf \implies f(x) = \sqrt{x+5}-1\\\\\bf\implies y = \sqrt{x+5}-1 \\\\\bf\implies x = \sqrt{y+5}-1 \:\:\bigg\lgroup \red{\sf Replacing \ x \ with \ y .} \bigg\rgroup \\\\\bf\implies x + 1 = \sqrt{y+5}\\\\\bf\implies y+5 = (x+1)^2 \\\\\bf\implies y+5 = x^2+1 +2x \\\\\bf\implies y = x^2+1-5+2x \\\\\bf\implies y = x^2-4+2x \\\\\bf\implies \boxed{\red{\bf f^{-1}(x)= x^2+2x - 4 }}[/tex]

Here I have also attached the graph of , x² + 2x - 4 and √(x+5) - 1. Here blue graph is of √(x+5) - 1 & red of x²+2x-4.

Answer:

0.36 hours

Step-by-step explanation:

Divide 4.5 with 12.5 mph.

=====================================

Work Shown:

EI = EG

3y-10 = 2y

3y-10-2y = 0

y-10 = 0

y = 0+10

y = 10

Note how if y = 10, then

Both EI and EG are 20 units long when y = 10. This confirms the answer.

Answer:

There were 7 players on the Bears

Step-by-step explanation:

Given

[tex]a = falcons[/tex]

[tex]b = bears[/tex]

We have that:

[tex]a = 11[/tex]

and also:

[tex]a = 2b - 3[/tex] --- 3 fewer than twice a

Required

Solve for b

Substitute 11 for a in [tex]a = 2b - 3[/tex]

[tex]11 = 2b - 3[/tex]

Add 3 to both sides

[tex]3+11 = 2b - 3+3[/tex]

[tex]3+11 = 2b[/tex]

[tex]14 = 2b[/tex]

Divide both sides by 2

[tex]\frac{14}{2} = \frac{2b}{2}[/tex]

[tex]7 = b[/tex]

[tex]b = 7[/tex]

Hence, there were 7 players on the Bears

Answer:

d

Step-by-step explanation:

Just divide 1,300 by 5.

260 would be your answer. If you want an explanation, if you think about the term 100%, that's the total at the time. Amplifying that 100% by five would practically mean five times the amount of 100%, so 500%. You're just multiplying the amount of bunnies at the time by 5. (500% in decimal form is 5)

Answer: 4983

Step-by-step explanation:

Initial population P=5500

Population declining at the rate of 1.4%

So, in the year 2010 population is

[tex]P=5500-5500\times1.4\%=5500(1-1.4\%)[/tex]

For the year 2011

[tex]P=5500(1-1.4\%)^2[/tex]

similarly, for the year 2016

no of years passed 2016-2009=7 years

[tex]P=5500(1-1.4\%)^7[/tex]

[tex]P=5500\times0.986^7\\P=5500\times0.90602\\P=4983.117\approx 4983[/tex]

Answer:

Henry's balloon was farther from the town at the beginning and Henry's balloon traveled more quickly.

Step-by-step explanation:

multiply 5x+2y=19 by 3 youll get 15x+6y=57

eliminate y

7x-6y=9

15x+6y=57 +

22x=66

x=3

substitute x to 5x+2y=19

15+2y=19

2y=4

y=2
