Answer:

B :step 2   she didnt collect all the like terms and calculate

Step-by-step explanation:

first rewrite  remove all (  )Parentheses

2nd   collect all like terms and calculate

a^4 + 7a -16 -12^a^3 + 5a -3

a^4 + 12a - 19 - 12a^3     ( Like terms are 7a +5a  and -16 +-3)

so she skipped the second step

Which system of equations is satisfied by the solution shown in the graph?

Answers

Answer:

(-2, 8) does not satisfy any system of the equation. In other words, no system of the equations satisfies the solution as shown in the graph.

Thus, not a single given option of the system of the equations satisfies the solution as shown in the graph.

Step-by-step explanation:

We know that the point of intersection of two lines on a graph is the solution of the system of equations.

From the graph, it is clear that the two lines intersect at x=-2 and y=8.

Thus, the point of intersection of the two lines is (-2, 8)

Putting the (-2, 8) in the first system of equations

x+2y=10              and              x-y = 6

-2+2(8)=10          and             -2-8=6  

14 = 10                 and               -10 = 6

L.H.S ≠ R.H.S       and               L.H.S ≠ R.H.S

L.H.S and R.H.S of both the system of equations are not equal, It means (-2, 8) does not satisfy the system of the equations x+2y=10  and x-y = 6.

Putting the (-2, 8) in the second system of equations

x+2y=6              and              x-y = 10

-2+2(8)=6          and             -2-8=10  

14 = 6                 and               -10 = 10

L.H.S ≠ R.H.S       and               L.H.S ≠ R.H.S

L.H.S and R.H.S of both the system of equations are not equal, It means (-2, 8) does not satisfy the system of the equations x+2y=6 and x-y = 10.

Putting the (-2, 8) in the third system of equations

x+y=6              and              x-y = 10

-2+8=6            and             -2-8=10  

6 = 6                 and           -10 = 10

L.H.S = R.H.S       and          L.H.S ≠ R.H.S

L.H.S and R.H.S of x-y = 10 is not equal, It means (-2, 8) does not satisfy the system of the equations x+y=6 and x-y = 10.

Putting the (-2, 8) in the second system of equations

x+y=6              and              x-2y = 10

-2+8=6             and             -2-2(8)=10  

14 = 6                 and             -18 = 10

L.H.S ≠ R.H.S       and               L.H.S ≠ R.H.S

L.H.S and R.H.S of both the system of equations are not equal, It means (-2, 8) does not satisfy the system of the equations x+y=6 and x-2y = 10.

In a nutshell, (-2, 8) does not satisfy any system of the equation. In other words, no system of the equations satisfies the solution as shown in the graph.

Thus, not a single given option of the system of the equations satisfies the solution as shown in the graph.

3. A geometric sequence g starts at 500 and has a growth factor of 0.6. Sketch a graph of g
showing the first 5 terms.

Answers

Answer:

Here you go! Sorry if its not in the correct format.

Hope this helps!

All five terms of GP are 500, 800, 1280, 2048, and 3276.8.

What is geometrical progression series?

A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.

For example, the sequence 1, 4, 16, 64,… is a geometric sequence with a common ratio of r = 4.

Given the first term 500

And it is growing by 0.6 factor

It means,

Second term = first term + 0.6 of first term

Second term = 500 + 0.6(500)

Second term = 500 + 300 = 800

And similarly, all three terms are 1280, 2048, and 3276.8.

Hence "All five terms of GP are 500, 800, 1280, 2048, and 3276.8".

4) The table below shows the price of paper plates at the grocery store. Find the unit price of
each brand, rounded to the nearest cent. Which is the best buy? Explain your reasoning.
Sturdy Plates 24 pack for $3.28
No Spill Plates 10 pack for $1.79
Compartment Plates 50 pack for $6.00

Answers

Answer:

Compartment plates is the best buy

Step-by-step explanation:

To find unit price, you can just divide the price by the number of plates

Sturdy plates: 3.28÷24= $0.14/plate

No spill plates: 1.79÷10 = $0.18/plate

Compartment plates: 6.00÷50 = $0.12/ plate

Out of all of the prices, $0.12 is the cheapest

Step-by-step explanation:

Answer:

x = 5

Step-by-step explanation:

Original Equation:

2(x + 2) = 14

Use distributive property

2 · x = 2x

2 · 2 = 4

Your equation should look like this now:

2x + 4 = 14

Subtract 4 from both sides.

2x = 10

Divide both sides by 2

x = 5

At the beginning of the year, Sadie had $70 in savings and saved an additional $18 each week thereafter. Jack started the year with $90 and saved $14 every week. Let S S represent the amount of money Sadie has saved t t weeks after the beginning of the year and let J J represent the amount of money Jack has saved t t weeks after the beginning of the year. Write an equation for each situation, in terms of t , t, and determine the amount of money Sadie and Jack have saved in the week that they have the same amount of money saved.

Answers

Answer:

$160

Step-by-step explanation:

Step one:

For Sadie

initial savings balance= $70

weekly savings = $18

Let S represent the amount of money Sadie has saved

and  t the number of weeks after the beginning of the year

The total amount in savings after t weeks is

S=18t+70-------1

For Jack

initial savings balance= $90

weekly savings = $14

Let J represent the amount of money Jack has saved

and  t the number of weeks after the beginning of the year

The total amount in savings after t weeks is

J=14t+90---------2

Step two

equation 1 and 2 to find t

18t+70=14t+90

18t-14t=90-70

4t=20

divide both sides by 4

t=20/4

t=5 weeks

so after 5 weeks Sadie and Jack will have the same amount of money

For Sadle t=5

S=18(5)+70-------1

S=90+70

S=$160

For Jack t=5

J=14(5)+90---------2

J=70+90

J=160

The two equations above shows that after 5 weeks their savings will be $160

Solve the equation.

I need to know if these two graphs are a function, is one a function? is two a function?

Answers

                                     Question 7

Answer:

The graph in question 7 is a function.

Step-by-step explanation:

In order to check whether the graph in question 7 is a function or not, we need to draw a vertical line anywhere on the graph, and if does not hit the graph more than once, it is a function.

It is observable that the vertical line will always intersect the graph in question 7 at the only place.

From the graph, it is clear the green vertical line intersects the graph at the only place. Hence, the graph in question 7 is a function.

Therefore, the graph in question 7 is a function.

                                               Question 8

Answer:

The graph in question 8 is not a function.

Step-by-step explanation:

In order to check whether the graph in question 8 is a function or not, we need to draw a vertical line anywhere on the graph, and if does not hit the graph more than once, it is a function.

It is observable that the vertical line intersects the graph in question 8 at more than one place.

From the graph, it is clear the green vertical line intersects the graph at x=-3 at more than one place. We can not have the same x values for the two output values in order to be a function. Hence, the graph in question 8 would NOT be a function.

Therefore, the graph in question 8 is not a function.
