q(x) = 2x+5
f(x)= x^2+1
find (gof)(7)

Answer:

-44

Step-by-step explanation:

Answer:

X = Y(W + Z)

Step-by-step explanation:

X/Y - Z = W

X/Y = W + Z

X = Y(W + Z)

Steps to solve:

-(1 + 4x) = 4(1 - x) - 5

~Distribute both sides

-1 - 4x = 4 - 4x - 5

~Combine like terms on the left side

-1 - 4x = -1 - 4x

~Add 4x to both sides

-1 = -1

~Add 1 to both sides

0 = 0

Therefore, all real numbers are solutions.

Best of Luck!

Answer:

36

Step-by-step explanation:

Answer:

A. 5x = 45

Step-by-step explanation:

To check, substitute 9 for x in each equation.

A. 5*9 = 45

B. 2*9 ≠ 20

C. 4 + 9 ≠ 12

D. 9 +7 ≠ 26

Answer:

height= 4.8cm

Step-by-step explanation:

volume= length×width× height given the volume and length and width, 288=12×5×h

288=60h

divide both sides by 60

h=4.8cm

h = 4,8 cm

m = 1152 g

V = l×w×h

h = V/l×w

= 288cm³/12cm×5cm

= 288cm³/60cm²

= 4,8 cm

1cm³ .............. 4g

288cm³ ........ xg

x = 288cm³×4g/1cm³ = 1152 g

Answer:

{x,y,z}={2,2,−2}

Step-by-step explanation:

Answer:

[tex]y = -\frac{2}{3} x - \frac{8}{3}[/tex]

Step-by-step explanation:

[tex]2x - 3y = 8\\[/tex]

Isolate y

[tex]-3y = 8-2x\\-3y = -2x+8[/tex]

Divide both sides of the equation by -3

[tex]\frac{-3y}{-3} = \frac{2x}{-3} +\frac{8}{-3} \\\\y = -\frac{2}{3} x - \frac{8}{3}[/tex]

awnser:

k= 75

5+13= 18                             = k

and your trying to get to 93 so 75+18=93 so

75=k

Answer:

Commutative property of multiplication

Step-by-step explanation:

This property states that numbers can be switched around when multiplying and the answer still remains the same

Answer:

C

Step-by-step explanation:

So we have the expression:

[tex]63\cdot 3[/tex]

And Jared rewrote it as:

[tex]3\cdot 63[/tex]

In other words, he just switched the order and the expression remains equivalent.

This is an example of the commutative property of multiplication, which states that if you change the order of a multiplication sentence, the sentence will remain equivalent.

So, our answer is C.

And we're done!

Answer:

[tex]\huge\boxed{\text{Maggie = 6 years, Brother = 21 years}}[/tex]

Step-by-step explanation:

We can create two equations based on the word problems, where [tex]m[/tex] is Maggie's age and [tex]b[/tex] is her brother's age.

[tex]m + b = 27[/tex]

[tex]b = 4m - 3[/tex]

We can now substitute [tex]4m-3[/tex] in as [tex]b[/tex] into [tex]m+b=27[/tex].

[tex]m + (4m-3) = 27\\\\5m - 3 = 27\\\\5m = 30\\\\m = 6[/tex]

Now that we know the value of [tex]m[/tex], we can substitute it into [tex]m+b=27[/tex].

[tex]6 + b = 27\\\\b = 27-6\\\\b = 21[/tex]

Hope this helped!

thus 24-6 = 18 more people can fit in the large airboat

Answer:

13) Luis is wrong because he read the 80* as if his starting point was P. He needs to now take away 45 because that is the angle PTQ.

14) 165* I'm pretty sure because you just do 45 plus 60 since the centred one would only have a view of 45 from what I understand and the other two still have a view of 60 each. Total is 165.

Answer:

8. AC = 29

x = 6

AB = 6

9. BC = 15

3x = 15

x = 5

BD = 3x +4x-13

= 22

10. <PTR = 80

11. < PTQ = 45

12. <QTS = 130 - 45 = 85

13. Luis didn't subtract 80 by 40

14. 180

Step-by-step explanation:

Let 'N' rep. Nancy's age

Let 'M' rep. Molly's age

1) 2N

2) M - 6

3) 2(10) = 20

therefore, Molly is 20

M = 20

M - 6 = 14 (Zander's age)

Answer:

Which expression represents Molly’s current age in terms of Nancy’s?

Answer: 2n

Which expression represents Molly’s current age in terms of Zander’s?

Answer: z plus 6

Nancy is currently 10 years old, and Zander is 14. How old is Molly?

Answer: 20 years old

Step-by-step explanation:

h(n)=4n+ 4 find h (-3)

h(-3)=4(-3)+4

=-12+4

=--8

Answer: -8

Step-by-step explanation: h(n) = 4n + 4 means that

if we put an n into our function, a 4n + 4 comes out.

So here, we're putting a -3 into our function which means that

a 4(-3) + 4 comes out which simplifies to -12 + 4 or -8.

So h(-3) = -8 or the value of the function at -3 equals -8.

Answer:

x ( > or = ) 5/9

Step-by-step explanation:

● 2(1 + x) ( > or = ) 11 - 3x

● 2 + 2x ( > or = ) 11 - 3x

Add 3x to both sides

● 2 + 2x + 3x ( > or = ) 11 - 3x + 3x

● 2 + 5x (> or = ) 11

Substract 2 from both sides

● 2 + 5x -2 ( > or = ) 11 -2

● 5x (> or =) 9

Divide both sides by 5

● 5x/5 ( > or = ) 5/9

● x ( > or = ) 5/9

Answer:

After 4 minutes

Step-by-step explanation:

Balloon 1

Balloon 2

Time required for the balloons to meet = x

After x minutes the first balloon will be at position:

And the second balloon will be at position:

Since they meet after x minutes, their position must be same:

So the balloons will meet after 4 minutes

Answer:

-1 4/5

Step-by-step explanation:

In mathematics, a fraction is a number that represents a part of a whole. It consists of a numerator and a denominator. The numerator represents the number of equal parts of a whole, while the denominator is the total number of parts that make up said whole. For example, in the fraction 3  5, the numerator is 3, and the denominator is 5. A more illustrative example could involve a pie with 8 slices. 1 of those 8 slices would constitute the numerator of a fraction, while the total of 8 slices that comprises the whole pie would be the denominator. If a person were to eat 3 slices, the remaining fraction of the pie would therefore be 5  8 as shown in the image to the right. Note that the denominator of a fraction cannot be 0, as it would make the fraction undefined. Fractions can undergo many different operations, some of which are mentioned below.

Answer:

198 inches^3

Step-by-step explanation:

Volume of a rectangular prism = Length × width × height

Length = 11 inches

Width = 6 inches

Height= 3 inches

Volume of a rectangular prism = Length × width × height

= 11 inches × 6 inches × 3 inches

= 198 inches^3

The volume of the rectangular prism with dimensions 11 inches long, 6 inches wide, 3 inches high is 198 cubic inches

Answer:

v = 200 m/s

Step-by-step explanation:

The formula for the speed of a tsunami in deep water is given by :

[tex]v=\sqrt{gh}[/tex]

Here,

g is acceleration due to gravity

h is the depth of the ocean in meters.

We need to find the speed at which the tsunami that started with an earthquake in Sumatra struck Sri Lanka about 1550 km away. The Bay of Bengal is 4 km (4000 m) deep.

It means we need to find v if h = 4000 m

So,

[tex]v=\sqrt{10\times 4000}\\\\v=200\ m/s[/tex]

So, the speed of the tsunami is 200 m/s.
