Answer

y=7x+2

Step-by-step explanation:

you have your slope already so keep slope but remove 5 and turn it into b in order to solve for new equation ...

y=7x+b

sub in (3,23) in your equation

23=7(3) +b

23=21 +b

23-21=b

2=b

your new equation should be y=7x+2

Answer:

y=-1/7+23 3/7

Step-by-step explanation:

Since it's parallel you take the y=7x+5 and the 7 is turned into -1/7(to find what's PARALLEL)

Now you put it into point slope formula to get: y-3=-1/7(x-3)

Simplify the equation.

Hope this helps(^-^)

Answer:

Step-by-step explanation:

2 cups of sparkling water with every 3 cups of apple juice = sparkling juice

Sparkling water : apple juice

2 : 3

How much sparkling water does Jada need if she uses 8 cups of apple juice.

Sparkling water : apple juice

x : 8

Equate both ratios

2 : 3 = x : 8

2/3 = x / 8

2*8 = 3*x

16 = 3x

x = 16 / 3

= 5.33 cups

Sparkling water = 5.33 cups

How much apple juice does Jada need if she uses 8 cups of sparkling water

Sparkling water : apple juice

8 : y

Equate both ratios

2 : 3 = 8 : y

2/3 = 8 / y

Cross product

2 * y = 3 * 8

2y = 24

y = 24 / 2

= 12

y = 12

Apple juice = 12 cups

NOTE: There is an error in your question, you wrote "How much sparkling water does Jada need if she uses 8 coups of sparkling water." but I solved for both sparkling water and apple juice using 8 cups since your question was not clear enough.

Answer:

where the green circle is where it goes

Answer:

  y = (-7/3)x +3

Step-by-step explanation:

The line has a negative slope (eliminating choices B and C) that is steeper than a line with a slope of -1, The only answer choice with a negative slope less than -1 is choice D.

__

The slope is the coefficient of x. It is "rise"/"run". Here, the line goes through grid points (0, 3) and (3, -4), so drops 7 units (rise=-7) for each 3 units to the right (run=3). Then the slope is rise/run = -7/3.

The line crosses the y-axis at y=3, so the slope-intercept equation is ...

  y = mx + b . . . . . . . . slope = m; y-intercept = b

  y = (-7/3)x +3

Answer:

42

Step-by-step explanation:

42/6=7

Answer:

42

Step-by-step explanation:

I hope this helps!

Answer:

y = -2x + 5

Step-by-step explanation:

Slope-intercept form is writen like this; y = mx + b. Where m = slope and b = y-intercept.

We know the slope, so, find the y-intercept.

y = -2x + b

3 = -2(1) + b

3 = -2 + b

5 = b

Put everything we know/solved for into the original formula.

y = -2x + 5

Best of Luck!

Answer:

35)The way to solve this is by making the decimal a fraction, 6tenths equals 6/10.

Now we find a common denominator,lets use 30.

multiply the 6/10 by 3 to get 18/30

multiply 2/3 by 10 to get 20/30

2/3 is greater than 0.6

Answer:

They cost the same amount

Step-by-step explanation:

Given

Lin: [tex]y = 5x +50[/tex] where x = 14

Max: [tex]\$120[/tex] for 14 days

Required

Which is less expensive?

Max charges has been given from the question as; $120 for 14 days.

To determine Lin's, we simply substitute 14 for x in [tex]y = 5x +50[/tex]

[tex]y = 5 * 14 + 50[/tex]

[tex]y = 70 + 50[/tex]

[tex]y =120[/tex]

The above result of y shows that Max charges for 14 days is also $120.

Hence, they (Lin and Max) cost the same because they both equal to $120 for 14 days

Answer:

962.5 is the answer

Step-by-step explanation:

One gallon cost 2.5 dollars and according to this 1*2.5=2.5+2*5=10........

The relationship between no. of gallons and the total cost of purchasing is in a linear relationship.

A linear relationship between two variable is when one variable is increased or decreased by some constant this results in same amount of increase or decrease in the another variable.

According to the given data

The relationship between the number of gallons of gas that are purchased and the total cost is in linear relationship.

A linear relationship forms when increasing a variable k times results in increase of k times on the another variable and same is for decrease.

We can observe when x = 1, y = 2.5.

Now suppose k is 10

∴ x = 1k and y = 2.5k

  x = 10 and y = 25. Which is already given in the diagram showing a linear relationship.

Answer:

x= 12 6/17

Step-by-step explanation:

Answer:

y = -5/3 * x - 40/3

Step-by-step explanation:

A perpendicular line has an opposite and a reciprocal of the slope.

Your equation should be:

-5y = -3x +6

Divide all parts by -5.

y = 3/5x - 6/5

Since the perpendicular line has an opposite and a reciprocal of the slope, the slope will be -5/3.

Now you must make an equation in point-slope form. This is an example of that form. You will need at least one point to make this equation work. In this case we have (-8,0).

In put the y and x coordinates like this:

y - 0 = -5/3(x - (-8)

Start solving the equation.

y - 0 = -5/3(x + 8)

y - 0 = -5/3 * x - 40/3

y = -5/3 * x - 40/3

This is your equation.

y = -5/3 * x - 40/3

(You can make it -5/3x in your answer but it looks weird online. You may think that it is -5 divided by 3 times x, but it actually is 5/3 times x. That's why I wrote it as y = -5/3 * x - 40/3)

Answer:

  5x +3y = -40

Step-by-step explanation:

When the equation of a line is given in standard form, the equation of the perpendicular line can be found by swapping the coefficients of x and y, and negating one of them.

Here, that means the equation ...

  3x -5y = constant

becomes

  5x +3y = new constant

The value of the new constant is found by putting the given point coordinates in the expression on the left:

  5x +3y = 5(-8) +3(0) = -40

The equation of the perpendicular line is ...

  5x +3y = -40

Answer:

Ada should buy 385 eggs from the store.

Step-by-step explanation:

Given that you know that Ada can make 40 egg tarts using 110 eggs, you can use a rule of three to find the amount eggs to make 140 egg tarts:

40 egg tarts    →  110 eggs

140 egg tarts  →         x

x=(140*110)/40=385 eggs

According to this, the answer is that Ada should buy 385 eggs from the store.

Answer:

23/14

=1.643

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

-11-(7*(1-2*f)+5)=0

-11 -  (7 • (1 - 2f) +  5)  = 0

14f - 23  = 0

3.1      Solve  :    14f-23 = 0  

Add  23  to both sides of the equation :  

                     14f = 23

Divide both sides of the equation by 14:

                    f = 23/14 = 1.643
