Answer:

y=3x+8

Step-by-step explanation:

m=3

y-(-1)=3(x-(-3))

y+1=3x+9

y=3x+8

The equation of the line passes through the point  (-3, -1)(and (-4, -4) is y=3x+8.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

m = slope

c = y-intercept

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given that line passes through the points (-3, -1)(and (-4, -4)

The slope will be calculated as,

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope = ( -4 + 1 ) / ( -4 + 3 )

Slope = 3

The y-intercept is calculated as,

y = 3x + c

-1 = 3 x -3 + c

c = 8

The equation of the line will be,

y=3x+8

Answer:

No, 80/10 turned into a whole number is 8, not -8.

Step-by-step explanation:

To get a whole (1), you need to have 10/10. Since we have 10/10 8 times (80/10) this means we get a whole number of 8, not -8. Therefore, its false. 80/10 is NOT equal to -8

Answer:

t+623

Step-by-step explanation:

If t is the number of hours Ivan worked as a tutor this month, you can say that the number of hours that Ivan worked as a waiter would be the result of subtracting the amount of hours he worked as a tutor this month from the combined total of hours he worked, which is:

89-t

After this, you can say that the combined total dollar amount Ivan earned this month is the result of adding up what he earned as a tutor plus the amount he earned as a waiter which is equal to 89-t. So, you would have:

8t+7*(89-t)

=8t+623-7t

=t+623

This means that the expression for the combined total dollar amount he earned this month is: t+623

Answer:

3 (5 x - 2) (y - 3)

Step-by-step explanation:

Factor the following:

15 x y - 6 y - 45 x + 18

Hint: | Factor out the greatest common divisor of the coefficients of 15 x y - 6 y - 45 x + 18.

Factor 3 out of 15 x y - 6 y - 45 x + 18:

3 (5 x y - 2 y - 15 x + 6)

Hint: | Factor pairs of terms in 5 x y - 2 y - 15 x + 6 by grouping.

Factor terms by grouping. 5 x y - 2 y - 15 x + 6 = (5 x y - 2 y) + (6 - 15 x) = y (5 x - 2) - 3 (5 x - 2):

3 y (5 x - 2) - 3 (5 x - 2)

Hint: | Factor common terms from y (5 x - 2) - 3 (5 x - 2).

Factor 5 x - 2 from y (5 x - 2) - 3 (5 x - 2):

Answer: 3 (5 x - 2) (y - 3)

Answer:

a. (6 * 50) + (6 * 3)

b. (6 * 40) + (6 * 13)

Step-by-step explanation:

Here, we want to use the distributive property to write equivalent expression .

We can have the given expression as follows;

6 * ( 50 + 3) = (6 * 50) + (6 * 3)

Furthermore, we can write the expression as;

6 * (40 + 13) = (6 * 40) + (6 * 13)

Answer: The area of the actual office space = 18 sq. yards

Step-by-step explanation:

Formula : Image length = Scale factor x original length

Given: A scale drawing of an office space uses a scale of 2 in. : 3 yd.

i.e. scale factor = [tex]\dfrac23[/tex]

The scale drawing has an area of 12 square inches.

i.e.   [tex]\text{12 sq. inches}=\dfrac23\times\text{area of the actual office space }[/tex]

[tex]\Rightarrow\ \text{Area of actual office space}=\dfrac{3}{2}\times12=18\text{ sq. yards}[/tex]

Hence, the area of the actual office space = 18 sq. yards

Answer:

16

Step-by-step explanation:

x∞y/z²

x=ky/z²(where k is the constant)

3=12/2²k

3=12/4k

3=3k

3÷3=k

therefore k=1

x=1y/z²

making y the subject

xz²=y

1(4²)=y

1×16=y

16=y

Answer:

Step-by-step explanation:

pls mark brainliest!

Given that y is directly proportional to x.

[tex] \sf y \propto x[/tex]

[tex]\longrightarrow \sf y = k \times x[/tex]

[tex]\\[/tex]

At first, we must find the value of k.

We have a relation given between 'x' and 'y' (that is, when 'x' is 75, 'y' is 60). We can call that Case - 1.

[tex]\sf 60 = k \times 75[/tex]

[tex]\longrightarrow \sf k = \dfrac{60}{75}[/tex]

[tex]\longrightarrow \sf k = \dfrac{4}{5}[/tex]

[tex]\\[/tex]

Now, we have to find 'x' when 'y' is 480. We can call that Case - 2.

[tex]\sf y = k \times x [/tex]

We are having the value of 'y' and 'k'.

[tex]\longrightarrow \sf 480 = \dfrac{4}{5} \times x[/tex]

[tex]\longrightarrow \sf x = 480 \times \dfrac{5}{4}[/tex]

[tex]\longrightarrow \sf x = 120 \times 5[/tex]

Answer:

Step-by-step explanation:

slope = M

M= rise / run

rise = Y2-Y1

run = X2 -X1

P1=(X1,Y1) = (3,-3)

P2=(X2,Y2) = (6,9)

M= 9-(-3)  /  6-3

M=12 /3

M=4

the slope is 4

a parallel line will have the same slope

a perpendicular line will have an inverse slope  or 1/4

Answer:

x = 10

x = 27

Step-by-step explanation:

53 and 5x + 3 are vertical angles.

vertical angles are equal.

using that, you can make this equation:

53 = 5x + 3

subtract 3 from both sides of the equation

53 - 3 = 5x + 3 - 3

50 = 5x

divide both sides of the equation by 5

50/5 = 5x/5

10 = x

82 and 3x + 1 are vertical angles.

vertical angles are equal.

using that, you can make this equation:

82 = 3x + 1

subtract 1 from both sides of the equation

82 - 1 = 3x

81 = 3x

divide both sides of the equation by 3

81/3 = 3x/3

27 = x

Answer:

The greatest length in feet the twines can be cut into with no twine left over is 4 feet

Step-by-step explanation:

To determine the greatest length a 20 feet long twine and a 12 feet long twine can be cut into such that the pieces are of the same length and no twine is left over, we will find the highest number that can be used to divide 20 and 12 with no remainder. Hence, we will find the Highest common factor (HCF) of 20 and 12.

Factors of 20 are: 1,2,4,5,10, and 20

and the factors of 12 are: 1,2,3,4,6, and 12

The highest common factors of 20 and 12 is 4.

Hence, the greatest length in feet the twines can be cut into with no twine left over is 4 feet.

Answer:

[tex]F = \frac{9}{5}(C + 32)[/tex]

Step-by-step explanation:

Given

[tex]C = \frac{5}{9}F - 32[/tex]

First, we need to solve for F

[tex]C = \frac{5}{9}F - 32[/tex]

Add 32 to both sides

[tex]C + 32 = \frac{5}{9}F - 32 + 32[/tex]

[tex]C + 32 = \frac{5}{9}F[/tex]

Multiply both sides by [tex]\frac{9}{5}[/tex]

[tex]\frac{9}{5} * (C + 32) = \frac{5}{9}F * \frac{9}{5}[/tex]

[tex]\frac{9}{5} * (C + 32) = F[/tex]

[tex]F = \frac{9}{5} * (C + 32)[/tex]

[tex]F = \frac{9}{5}(C + 32)[/tex]

Next, is to determine the temperature in degrees Fahrenheit

However, this is not stated the degree Celsius equivalent is not stated in your question.

So, I'll assume a value for it.

Assume that C = 23

Substitute 23 for C in [tex]F = \frac{9}{5}(C + 32)[/tex]

[tex]F = \frac{9}{5}(23+ 32)[/tex]

[tex]F = \frac{9}{5}(55}[/tex]

[tex]F = 9 * 11[/tex]

[tex]F = 99[/tex]

Answer:

Step-by-step explanation:

We can use the equation of a straight line as a concept to solve this problem

that is y=mx+c

at the end of the 12 weeks we can estimate the total distance that Emmanuel must have covered.

Given data.

the total distance is y

the number of weeks is x

and the starting distance is c (based on the equation of line)

starting distance= 5 miles,

increment = 2miles each week

number of weeks =12

substituting we have

y=2(12)+5

y=24+5

y=29miles

the total distance covered after 12 weeks is 29miles
