is this a function? pls help

[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:

$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:

(-4,0)

Step-by-step explanation:

plzz follow me

(-4,0) is the solution of the set to the system of inequalities

a relationship between two expressions or values that are not equal to each other is called 'inequality.

The given two inequalities are

y<-3x-6 and 4x-2y<-8

Let us check for (-4, 0)

0<-3(-4)-6

0<6

4x-2y<-8

4(-4)-2(0)<-8

-16<-8

So (-4, 0) is the solution of the inequalities.

Now let us check for (0, 2)

replace y value as 2 and x as 0.

2<-3(0)-6

2<-6

Which is not true.

Hence, (-4,0) is the solution of the set to the system of inequalities.

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

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.

3x=34.2

3x /3 = 34.2 /3

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:

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

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

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

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)
