A shop sells packets of envelopes.
There are 5 envelopes in a small packet.
There are 20 envelopes in a large packet.
There is a total of T envelopes in x small packets and y large packets.
Write down a formula for T in terms of x and y.

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

                                     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.

ok this triangle is an isosceles triangle because when you tell sit and look at the base sides that is 55° and be those are the base angles so if one is 55 the other one is also 55 So B is 55

Answer:

B=55°

Step-by-step explanation:

That is an isosceles triangle TS and US are the same size. So the 2 angles at the base (TU) will be the same. so b=55°

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

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".

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.

Answer:

Slope-1/4 Y-intercept--2 Equation-y=1/4x+-2 and choose any point on the line.

Step-by-step explanation:

To find slope, you will have to make a slope triangle with two intersecting points. Divide h/v witch is 1/4. The y-intercept is just the point on the y-axis so that is -2. For the fourth question, just choose any coordinate on the oblique line.

Answer:

x=5

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

Answer:

11/6 or 1.8333333333

Step-by-step explanation:

[tex]\frac{2x + 1}{6}[/tex] = [tex]\frac{7}{9}[/tex]

Cross Multiply:

7 x 6 = 42

9 (2x+1)

42 = 9(2x+1)

42 = 18x + 9

Then, isolate the variable. In order to do so, subtract 9 from both sides.

33 = 18x

Now, divide by 18 (to find x)

33/18 =

1.8333333 or 11/6

Answer:

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
