Find the slope of the line.

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

Make it a mixed number.

1  21/50

The number 142 % in mixed number form is 1 21/50

What are Mixed Numbers?

A mixed number is a whole number, and a proper fraction represented together. A mixed number is formed by combining three parts: a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper fraction that makes the mixed number.

Given data ,

The number given is = 142 %

On simplifying , we get

142 % = 100 % + 42%

We know that 100 % = 1

So ,

42 % = 42 / 100

Divide by 2 on both numerator and denominator , we get

21 / 50

So , the number 142 % is written as 1 21/50

Or ,

Simplifying 142 / 100 , we get

142 / 100 = 71 / 50

Converting 71 / 50 into mixed number , we get 21 as the remainder ,

Therefore , the mixed number form of 71 / 50 is 1 21/50

Hence , the mixed number form is 1 21/50

Answer:

[tex]3x-4y[/tex]

Step-by-step explanation:

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

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.

Answer:

A)6, 2, -2,-6

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

The equation of the line in slope-intercept form is:

Step-by-step explanation:

Given the points

Finding the slope

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-8,\:5\right),\:\left(x_2,\:y_2\right)=\left(-1,\:-5\right)[/tex]

[tex]m=\frac{-5-5}{-1-\left(-8\right)}[/tex]

[tex]m=-\frac{10}{7}[/tex]

We know the slope-intercept form of the line equation is

[tex]y = mx+b[/tex]

where m is the slope and b is the y-intercept

substituting m = -10/7 and (-8, 5) in the slope-intercept form to determine the y-intercept

[tex]5\:=\:\frac{-10}{7}\left(-8\right)+b[/tex]

[tex]\frac{80}{7}+b=5[/tex]

[tex]b=-\frac{45}{7}[/tex]

now substituting m = -10/7 and b = -45/7 in the slope-intercept form

[tex]y = mx+b[/tex]

[tex]y\:=\:\frac{-10}{7}x+\left(-\frac{45}{7}\right)[/tex]

[tex]y\:=\:\frac{-10}{7}x-\frac{45}{7}[/tex]

Thus, the equation of the line in slope-intercept form is:

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.

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

2 + 4 + 2b = 20.

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:

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.

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

Answer:

going on by 2 every

Step-by-step explanation:

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.

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.

The number of students going on the trip is 60.

Given that, total cost = $4220

Cost per student= $30+$40=$70

Additional cost = $20

We need to find the number of students.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Let the number of students be x.

Cost paid by students = 4220-20 = 4200

Number of students = cost paid by students/cost per student

x = 4200/70

⇒x= 60

Therefore, the number of students going on the trip is 60.

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

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.

Step-by-step explanation:

Number 1) Don’t get confused with the -10 and 10, we already know that the value is already 20 so that narrows it to 2 choices. Now everytime you move on, it subtracts 10 so its 20:-10

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
