Select all expressions that represent a correct solution to the equation 6(x + 4) = 20.

Answer:

the graph has the largest slope. the slope is 5/2

Step-by-step explanation:

the slope of y=2x+4 is 2.

to get the slope of the table, see how much x increases and how much y increases. in this case, as x increases by 1, y also increases by 1, so the slope is 1.

to get the slope of the graph, find two or three points with whole numbers as both the x and y values. we can use (0, 2) and (2, 7). we can either make another table to see how the x and y values increase or look at the line and see how the line rises and runs. in this case, as x increases by 2, y increases by 5. the y value shows rise and the x value shows run, so we can write the slope as 5/2. we can see how the line rises by 5 and goes 2 units to the right. this gets the same slope as before.

1<2<5/2, so the graph has the largest slope.

Answer:

Each DVD was 11 dollars

Step-by-step explanation:

First let's make our equation

Lets read our equation and take the most important parts of it

                             Most important parts put into a equation

Let d represent DVD's

                                                [tex]55-7d=-22[/tex]

Subtract both sides by [tex]55[/tex]

                                                [tex]-7d=-77[/tex]

Divide both sides by [tex]-7[/tex]

                                                  [tex]d=11[/tex]

Each DVD was 11 dollars

Answer:

6.9

Step-by-step explanation:

Use the Pythagorean theorem :

a^2 + b^2 = c^2

so,

11^2 + b^2 = 13^2

121 + b^2 = 169

b^2= 48

b = 6.928

Round to the tenth : 6.9

Answer:

[tex]-33\sqrt{6}[/tex]

Step-by-step explanation:

We have to simplify [tex]\sqrt{54}[/tex] to [tex]3\sqrt{6}[/tex]

Then rewrite that as

[tex]-11*3\sqrt{6}[/tex]

Then simplify by multiplying only -11 and 3

[tex]-33\sqrt{6}[/tex]

Step-by-step explanation:

f(x) = 2x

g(x) = x² + 8

(f × g)(x) = f(x) × g(x)

= 2x(x² + 8)

= 2x.x² + 2x. 8

= 2x³ + 16x

(f×g)(x) = 2x³ + 16x

Answer:

22

Step-by-step explanation:

3.85+2.75= 6.6

6.6÷0.30= 22

Answer:

The answer is 22 loaves of bread.

Step-by-step explanation:

You add 3.85 pounds + 2.75 pounds to get the total number of pounds she bought, which is 6.6 pounds of bananas.

Then you divide your total answer of 6.6 pounds by 0.30 pounds for each loaf, to get 22 loaves of bread.

Answer:

A and C

Step-by-step explanation:

A. Like terms have the same variable like -6y and 7y. If it was -6y squared and 7y, they would NOT be like terms.

B. 6 is a coefficient (number), not a variable.

C.  5 is the coeffecient (it 's being multiplied by x)

D. A constant term is a number.

Answer:

¹/₄ hr or 0.25 hrs

⁷/₆ hr or 70 mins

He will make it in time (justification below)

4.

a. False

b. True

c. False

Step-by-step explanation:

The questions are all in relation to the equation:

speed (km/hr) = distance (km)/time (hr)

It may be worth learning about how formula triangles work because I think you would find them helpful, there are videos online on this

The first question is asking about times;

Rearranging the equation/formula above, time = distance/speed;

So, we just plug in the information for each distance travelled;

The first 30 km is covered at 120 km/hr;

So, the time taken will be:

t = ³⁰/₁₂₀

This simplifies to:

t = ¹/₄ = 0.25

So, it will take ¹/₄ hr or 0.25 hrs to cover 30 km at 120 km/hr;

¹/₄ hr is the same as 15 mins

The next 56 km is covered at 48 km/hr;

So:

t = ⁵⁶/₄₈

This simplifies to:

t = ⁷/₆

So, it will take ⁷/₆ hr or 70 mins

The second question requires us to know the time taken to cover 16 km at 100 km/hr;

t = ¹⁶/₁₀₀

This simplifies to:

t = ⁴/₂₅ = 0.16

So, ⁴/₂₅ hr or 9.6 mins

If he has 15 mins to make it to school and we've just calculated it will taken 9.6 mins, then he will make it in time

4.

a.

False

Jason runs 5 km in 30 mins, which means he could run 10 km in 60 mins;

Donna runs 9 km in 60 mins, so Jason runs at a faster speed since he would cover 10 km in 60 mins

b.

True

Rachel covers 10 km in 10 mins;

Speed will be:

10/10 = 1

So, her speed is 1 km/min

An hour is 60 mins so, her speed in km/hr will be:

60 × 1 = 60

60 km/hr

This is greater than the limit 50 km/hr

c.

False

The 2 runners run the same track, this means they run the same distance;

If James takes longer, then this is because he is running slower or, in other words, Paula is running faster

Ice cream is alwasy teh answer

Answer:

A. y = 5/2x – 14

Step-by-step explanation:

Find the slope of the original line and use the point-slope formula  y − y 1 = m ( x − x 1 )  to find the line parallel to  y = 5 /2 x − 10 .

y = 5 /2 x − 14                PARALLEL

...................................................................................................................................................

Find the negative reciprocal of the slope of the original line and use the point-slope formula  y − y 1 = m ( x − x 1 )  to find the line perpendicular to  y = 5 /2 x − 10 .

y = − 2 /5 x − 157 /5                        PERPENDICULAR

Step-by-step explanation:

13.5-11.5=2

2/11.5=.1739…

.1739*100= 17.39

Answer:

x = -2

Step-by-step explanation:

1) Rewrite the equation to remove unnecessary parenthesis: x + 5 + 5 - x + x + 2 = 10

2) Remove the opposite variables: 5 + 5 + x + 2 = 10

3) Calculate the sum of the numbers on the lefthand side: 12 + x = 10

4) Subtract 12 from both sides so that x is by itself: x = 10 - 12

5) Solve the equation on the right, and you get your answer: x = -2
