8(x -3) +7 = 2x (-13)   here was the error because the had 13 that is incorrect

8x -24 +7 = -26x

8x -17 = -26x

-17 = -26x -8x

-17 = -34x

-17/-34 = x

How do you get from one number to the next using multiplication or division?
From 100 to 106.

Answers

We can move from 100 to 10^6 by multiplying with 10^4.

How do you use  multiplication?

We know that it is possible to move from one value to another by the use of multiplication or division. Now in either case, there is a value that we have to us to multiply or divide another number order to move from one number to another.

Now we have the number 100 and we want to change it to 10^6. The implication of this is that the number 100 must have to be multiplied by the number 10^4 in order to arrive at the expected destination.

Thus;

100 * 10^4  = 10^6

Work out the equation of a line which has a gradient of 3 and passes through the point (-1,3)

Answers

The equation of line is given as : y = 3x + 6

According to the question we have been given that the line passes through the points (-1,3) and has gradient 3

We need to find the equation of line. The general form of slope intercept form is

              y = mx + c

where,  m = slope

            c = intercept

When a point and slope is given then the expression for the equation of line is given as:

                   [tex](y - y_{1})=m(x-x_{1})\\[/tex]          (1)

where (x1,y1) are the coordinates which is (-1,3)

           m = slope or gradient = 3

Putting the required values in  equation (1) we get

                 (y-3) = 3(x+1)

                  y-3 = 3x + 3

                   y = 3x + 6

Hence the equation of line is given as : y = 3x + 6

10. A washing machine repairer charges a total of £T for a repair which takes H hours. The formula
connecting T and H is
T = 35 + 20H.
Find H when T is 85.

Answers

The value of H when T is 85 is 2.5 hours which is calculated from the linear equation in two variables.

The linear equation in two variables is defined as an equation which defines the relationship between two unknown variables.

The general form of linear equation is of the form ax + by = c where a and b are constant co-efficient and c is a constant. Here y is the dependent variable and x is the independent variable.The graph of a linear equation in two variables is a straight line in the cartesian plane.

Given the linear equation for total amount of money(T) which is the dependent variable using the independent variable H(number of hours worked) .

T=35 + 20 H

At T = 85 , we substitute the value of T in the linear equation to find H .

T=35 + 20 H

or, 85 = 35 + 20H

or, 50=20H

or, H=2.5

Therefore the value of H is 2.5 hours when T is 85.

C)10, 6, 2,-2

D)14, 18, 22, 26

Answers

Answer:

Step-by-step explanation:

a(n) = a +(n-1)d

a(n) = a +dn-d

a(n) = a-d + dn

a(n) = 10 - 4n

So d=-4

to get a: (a-d)=10

             a=10-4=6

The first four  terms:

a(1) = 6 +(1-1)-4=6

a(2) = 6 +(2-1)-4=2

a(3) = 6 +(3-1)-4=-2

a(4) = 6 +(4-1)-4=-6

A recipe uses 1/3 cup of flour and 1/8 cup of sugar.How much flour and sugar does the recipe use altogether?

Answers

Answer:

11/24

Step-by-step explanation:

Just add 1/3 and 1/8 to get the answer. To add or subtract any pair of fractions they must have the same denominator. To change them, find the least common multiple of the two denominators (3 and 8). The least common multiple of 3 and 8 is 24. Now multiply the denominator by a number that’ll make it into the least common multiple. The 3 in 1/3 should be multiplied by 8 to make it into 24. The 8 in 1/8 should be multiplied by 3 to make into 24. The number that you use to multiply each denominator should also be used to multiply the numerator of that fraction. 1/3 for example, becomes 8/24. 1/8 becomes 3/24. Finally add the numerators of both numbers and keep the same denominator which equals 11/24.

Number 2) This one is pretty easy, we know that he drives about 12,000 miles a year but we don’t know how many years, so that unknown variable would be (x), now the 40,000 miles was already on it so that can’t change, only The years change so therefore the equation could be 12,000x+40,000

graph the following state and show the a h and k values.
y=2(x+3)^2-4

Answers

This equation is in vertex form. Vertex form is y=a(x-h)^2+k, where (h,k) is the vertex. In this equation, h= -3, and k= -4. So, the vertex would be at (-3,-4). A tells us if the parabola will be positive or negative. In this case, it is positive, so the parabola opens upward. Then, you can solve for x-intercept by letting y=0 and solving for x. Then, you can find the y-intercept by setting x=0 and solving for y. Finally, graph the parabola.

The historical records state that the long-lost temple of the sun had a perimeter of about 220 meters and an area of about 2,100 square meters. Do you think the archaeologists actually discovered the lost temple?

Answers

Answer:

The archaeologists dis not actually discovered the lost temple

Step-by-step explanation:

For us to be able to determine if the archaeologist actually discovered the lost temple, we need to find the dimension of the temple first.

Area of the temple = LW

Perimeter = 2L + 2W

L is the length

W is the width

If the perimeter is 220m

220 = 2L + 2W

110 = L+W ... 1

If the area is 2100 square meters

A = LW

2100 = LW ... 2

From 1;

L = 110 - W .... 3

Substitute 3 into 2

From 2;

2100 = LW

2100 = (110-W)W

2100 = 110W - W²

- W² + 110W - 2100 = 0

W² - 110W + 2100 = 0

Using the general formula;

W = -(-110)±√(-110)²-4(1)(2100)/2

W = 110±√3700/2

W = 110±60.83/2

W = 110±60.83/2

W = 110+60.83/2 and W = 110-60.83/2

W = 170.83/2 and 49.17/2

W = 85.415m and 24.585m

Substitute the width into the formula to get the length;

LW = 2100

L = 2100/W

L = 2100/85.415

L = 24.59 m

If the width is 24.585m;

L = 2100/24.585

L = 85.42m

Since we have different dimension of the temple, this show shat the archaeologists dis not actually discovered the lost temple

Graph a line that contains the point (6,-5) and has a slope of -2/3

Answers

Answer:

The line to graph is y=-[tex]\frac{2}{3}[/tex] -1

Step-by-step explanation:

In order to graph the line, it needs to be in slope-intercept form. We can make an equation in slope intercept form by using the point-slope form, which is y-y₁=m(x-x₁).

1. Plug info into point-slope form:

y-(-5)=-[tex]\frac{2}{3}[/tex](x-6)

2. Simplify:

y+5=-[tex]\frac{2}{3}[/tex] x+4

3. Simplify even further:

y=-[tex]\frac{2}{3}[/tex] -1

To graph the line, make a point a (0,-1). From here, go down 2 points and to the right 3 points. Continue the pattern and connect the points with a line.

If a term doesn't have a coefficient , it is considered that the coefficient is 1

[tex]2x+1x-4y[/tex]

Why is it considered that the coefficient is 1?

Remember that any term multiplied by 1 remains the same:

[tex]1.x=x[/tex]

Step 1

The equality can be read in the other way as well , so any term can be written as a product of 1 and itself:

[tex]x=1 . X \\[/tex]

Step 2

Usually, we don't need to write multiplication sign between the coefficient and the variable , so the simpler form is:

[tex]x=1x[/tex]

That is why we can write the term without the coefficient as a term with coefficient 1.

Answers

Using a system of equations, the equation that determines how many balloons each friend receives is given by:

2 + 4 + 2b = 20.

What is a system of equations?

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

For this problem, the variables are given as follows:

Variable s: number of sodas bought.Variable c: number of candy bars bought.Variable b: number of balloons bought.

You want to buy 2 sodas for Jake, 4 candy bars for Julian, hence:

s = 2, c = 4.

An equal number of balloons b, hence 2b is added to the equation, as the amount has to be 2, 4, 6, and so on, considering one balloon for each.

The total amount of money is of $20, hence the equation is:

2 + 4 + 2b = 20.
