What is the value of x in the figure? Enter your answer in the box.
PLease answer fasttttt

Answer:  (d) x

Step-by-step explanation:

Inverses cancel each other leaving you with whatever is in the parenthesis.

Examples:

f(g(x)) = x

f(g(1)) = 1

f(g(2bc) = 2bc

Answer: The equations have no solution because no solution graphs have the same slopes but difference y- intercepts.And by looking at the equations they both have same slope as 3 but different y-intercepts 5 and -5.

Step-by-step explanation:

y= 3x + 5

y = 3x- 5

3x + 5 = 3x -5

-3x          -3x

       5 ≠ 5  

Answer:

Costs are $490

49 shirts are sold

Step-by-step explanation:

98 + 8x = 10x

98 = 2x

49 = x

98 + 8(49) = $490 in costs

49 shirts sold

Answer:

[tex]68\frac{1}{4}[/tex] pounds

Step-by-step explanation:

The combined weight of 13 bags is 13 multiplied by the weight of each bag.

The weight of each bag is [tex]5\frac{1}{4}[/tex] pounds. Therefore, the weight of 13 bags is:

[tex]5\frac{1}{4} * 13\\ \\= \frac{21}{4} * 13\\[/tex]

[tex]= 68\frac{1}{4}[/tex] pounds

Answer:

16.5x = 465.3

Step-by-step explanation:

The distance traveled is equal to the gallons time the miles per gallon

465.3 = 16.5 * x where x is the miles per gallon

16.5x = 465.3

∠5 = 118

Step-by-step explanation:

If you look closely at this image, you can see that ∠6 and ∠5 together will be equal to line c.

A straight line is equal to 180 so if we do...

[tex]180-62[/tex]

= 118.

∠5 will be equal to 118.

If we go even further, because vertical angles are congruent...

∠7 = 62

∠8 = 118

Answer:

[tex] m \angle \: 6 = 118 \degree[/tex]

Step-by-step explanation:

[tex]m \angle \: 5 + m \angle \: 6 = 180 \degree.. (straight \: line \: \angle s) \\ \because \: m \angle \: 5 = 62 \degree \\ \therefore \: 62 \degree+ m \angle \: 6 = 180 \degree \\ \therefore \: m \angle \: 6 = 180 \degree - 62 \degree \\ \huge \red{ \boxed{\therefore \: m \angle \: 6 = 118 \degree}}[/tex]

Answer:

Step-by-step explanation:

1+1

Answer:

-2x^2-8x+12

Step-by-step explanation:

f(x)= 3x^2-2x+4

g(x)= 5x^2 +6x -8

(f-g)(x) =  3x^2-2x+4-(5x^2 +6x -8)

Distribute the minus sign

(f-g)(x) =  3x^2-2x+4-5x^2 -6x +8

Combine like terms

-2x^2-8x+12

Answer:

28

Step-by-step explanation: You need to divide 7 by 1/4. Whenever you divide fractions you keep the first number as it is, change the sign to multiplication and write the reciprocal of the second fraction which is you have to flip the fraction. It is going to be 7 times 4/1. Which is 28/1 which is 28.

Answer:

x=3, y=15

Step-by-step explanation:

We substitute 5x for y, getting 5x = -3x + 24. We add 3 x to both sides, and have a equation like this: 8x = 24. Divide by 8 on both sides, and we know that x = 3. Since y is 5x, y is 5*3, which is 15.

Answer:

x = -8

Step-by-step explanation:

solve:

-4(2x+3) =2x+6-(8x+2)

-8x-12 = 2x+6-8x-2

-8x-12 = -6x + 4

-2x = 16

x = -8

Hope this helps.

Good Luck

Answer:

[tex]x = - 8[/tex]

Second answer is correct

Step-by-step explanation:

[tex] - 4(2x + 3) = 2x + 6 - (8x + 2) \\ - 8x - 12 = 2x + 6 - 8x - 2 \\ - 8x - 12 = - 6x + 4 \\ - 8x + 6x = 12 + 4 \\ - 2x = 16 \\ \frac{ - 2x}{ - 2} = \frac{16}{ - 2} \\ x = - 8[/tex]

hope this helps

brainliest appreciated

good luck! have a nice day!

Answer:9

Step-by-step explanation:

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator. Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1. (14/2 x 3/3)+(12/6 x 1/1). Complete the multiplication and the equation becomes  42/6+12/6. The two fractions now have like denominators so you can add the numerators. 42+12/6=54/6. Divide 54 by 6 and get 9. hope this helps :)

Answer:

Step-by-step explanation:

Given the distance of a swinging pendulum modeled by the equation P(t)=−5cos(2πt)+5, to get the first time the pendulum reaches 3.5cm, we will have to substitute P(t)= 3.5cm into the given equation and calculate the value of 't' as shown;

3.5 = −5cos(2πt)+5

Subtracting 5 from both sides;

3.5-5 = −5cos(2πt)+5-5

-1.5 = −5cos(2πt)

Dividing both sides by -5 will give;

[tex]\frac{-1.5}{-5} = cos2\pi t\\0.3 = cos2\pi t\\2\pi t=cos^{-1} 0.3\\2\pi t = 72.54^{0} \\360t = 72.54^{0} \\t = \frac{72.54}{360} \\t = 0.20secs[/tex]

The first time the pendulum reaches 3.5cm is after 0.20secs

Answer:

Step-by-step explanation:

Answer:

y = (x + 4)(x + 3)

Step-by-step explanation:

y = x ^2 + 7x + 12

The two numbers must add up to 7 and has a product of 12, and since the equation is all positive, then the two numbers are positive too.

So y = (x + 4)(x + 3) is the answer.

Check:

y = (x + 4)(x + 3)

y = x(x + 3) + 4(x + 3)     distributive property

y = x^2 + 3x + 4x + 12

y = x^2 + 7x + 12
