Help pls thank you!!!

(NOTE: many questions may ask you to put the equation in a certain format. This answer is assuming you can put it in slope-intercept form.)

Answer:

y= -3x-3

Step-by-step explanation:

1) A handy way to write an equation from a graph is to use the slope-intercept form: y = mx + b. In this format, the "m" represents the slope - or the measure of the steepness of the graph (we'll get more into this in the next step). The "b" represent the y-intercept, or where the point in which the graph hits the y-axis. If you know what the slope and y-intercept is, it is very easy to create an equation!

2) So let's find the slope first. The slope of an equation is represented by [tex]\frac{rise}{run}[/tex] , or the change in the y from each point, going up or down, divided by the change of x, going from left to right. So, knowing this, we can take two points we see the line hit and count the change from the x and y values.

3) Now, let's find the y-intercept. This part is much easier: just look at the graph and find the point where the line hits the y-axis. In this case, it's (0,-3).

4) All you have to do now is plug the slope and y-intercept we found into y = mx + b. So, put the slope in the "m" place and remember to put the y-value of the y-intercept into the "b" place.

This should get you y= -3x - 3 as your answer!

Answer:

x = 2.825

Step-by-step explanation:

-4.3(6.3x + -4.18) = -58.56

-4.3(-4.18 + 6.3x) = -58.56

(-4.18 * -4.3 + 6.3x * -4.3) = -58.56

(17.974 + -27.09x) = -58.56

17.974 + -27.09x = -58.56

17.974 + -17.974 + -27.09x = -58.56 + -17.974

0.000 + -27.09x = -58.56 + -17.974

-27.09x = -58.56 + -17.974

-27.09x = -76.534

x = 2.825175341

Answer:

I think that removing (1, 3) would make the most sense

Answer:

(1,3)

Step-by-step explanation:

Because (1,-2) and (1,3) have the same x value, they do not pass verticle line test, so it is not a function.

Answer: A.

Answer:

a = b = 40°

Step-by-step explanation:

∠ a and 140° are adjacent and are supplementary , thus

a = 180° - 140° = 40°

a and b are alternate angles and are congruent, thus

b = a = 40°

Answer:

b=40 okkkkllllllkkkkkkkkkkkkkkkkkkkkkllllllkkkk

Answer:

Answer:

x = m - z

Step-by-step explanation:

z = m - x       add x to both sides

z + x = m - x + x

z + x = m            subtract z from both sides

z - z + x = m - z

x = m - z

Answer:

-z + m = x

Step-by-step explanation:

z = m-x

subtract the m from both sides

z-m = -x

you can't have a negative x so multiply everything by -1

-1(z-m = -x)

-z + m = x

Answer:

2y = x + 2

Step-by-step explanation:

Looking at the graph, we can see from one point to the next (from right to left), the x-value rises by 2 and the y-value by 1;

From this we can work out the gradient between two points using the formula, i.e. the change/difference in y divided by the change/difference in x:

[tex]m = \frac{dy}{dx} = \frac{1}{2}[/tex]

Joining the points gives a straight line, which means a constant gradient of ¹/₂

Use the line equation formula to get the function:

y - y₁ = m(x - x₁)

m = ¹/₂

x₁ = 0

y₁ = 1

y - 1 = ¹/₂.(x - 0)

y - 1 = ¹/₂.x

2y - 2 = x

2y = x + 2

Answer:

7. (2,1) 8. (8,2)

Step-by-step explanation:

Step: Substitute4z−7foryin5y+3z=11:

5y+3z=11

5(4z−7)+3z=11

23z−35=11(Simplify both sides of the equation)

23z−35+35=11+35(Add 35 to both sides)

23z=46 Divide both sides by 23

x=2

Substitute2forxiny=4z−7:

y=4z−7

y=(4)(2)−7

y=1

Step: Solve2x+4y=24for x:

2x+4y+−4y=24+−4y(Add -4y to both sides)

2x=−4y+24

x=−2y+12

−2y+12forxin−2x+8y=0:

−2x+8y=0

−2(−2y+12)+8y=0

12y−24=0(Simplify both sides of the equation)

12y−24+24=0+24(Add 24 to both sides)

12y=24 Divide both sides by 12

y=2

Substitute2foryinx=−2y+12:

x=−2y+12

x=(−2)(2)+12

Answer:

Albert needs 32 cars to wash to reach his goal.

Step-by-step explanation:

We know that the slope-intercept form of a linear function is

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

where m is the slope or rate of change and b is the y-intercept

It is stated that Albert needs $133 to buy a new hard drive.

As earns $4.75 for each car he washes. Thus, $4.75 the rate of change or slope will be.

As he spends $19 on supplies. Since it is an expense, so -19 is basically the y-intercept 'b'.

Let 'x' be the number of cars he needs to wash to reach his goal.

Thus, substituting the value m = 4.75, y = 133, and b=-19 in the slope-intercept form of a linear function

y = mx+b

133 = 4.75x - 19

133+19 = 4.75x

152 = 4.75x

x = 152 / 4.75

x = 32

Therefore, Albert needs 32 cars to wash to reach his goal.

Answer:

the price of the pair of shoes are $57.60

Step-by-step explanation:

So you first need to find out what 10% is in $64 so your going to multiply 0.1 (10% in decimal form is 0.1 ) by 64 to get 10% of the original price.

64 * 0.1 = $6.40

so now we are going to subtract $6.40 from $64 for the sale price:

$64.00 - $6.40 = $57.60

so the sale price is $57.60

Answer:

[tex]Measurement = 0.75ft[/tex]

Step-by-step explanation:

See attachment for complete question

Method 1:

Considering the width and length of the quilt

Given

[tex]Number\ of\ squares = 24[/tex]

Required

Determine the dimension of 1 square

The width of the quilt is 4.5ft and there are 6 squares in that dimension.

Each measurement is calculated as thus:

[tex]Measurement = \frac{4.5ft}{6}[/tex]

[tex]Measurement = 0.75ft[/tex]

Or

The length of the quilt is 3ft and there are 4 squares in that dimension.

Each measurement is calculated as thus:

[tex]Measurement = \frac{3ft}{4}[/tex]

[tex]Measurement = 0.75ft[/tex]

Method 2:

Calculate the area of the quilt.

[tex]Area = 4.5ft * 3ft[/tex]

[tex]Area = 13.5ft^2[/tex]

The area of 1 of the 24 squares is calculated by dividing the total area by number of squares

[tex]Area = \frac{13.5ft^2}{24}[/tex]

[tex]Area = 0.5625\ ft^2[/tex]

Represent the dimension of individual square with L

Area of a square is:

[tex]Area = L * L[/tex]

This gives:

[tex]L * L = 0.5625[/tex]

[tex]L^2 = 0.5625[/tex]

Take square root of both sides

[tex]L = \sqrt{0.5625[/tex]

[tex]L = 0.75ft[/tex]

Hence, the dimension of each square is 0.75ft
