Answer 1

Answer:

Answer:

y = 5x + 3

Step-by-step explanation:

Step 1. Find the slope

Each time x increases by 1 unit, y increases by 5 units.

m = slope = 5/1 = 5

Step 2. Find the y-intercept.

y = mx + b

When x = 4, y = 23.

23 = 5×4 + b

23 = 20 +b

b = 3

y = 5x + 3

The graph is a straight line with slope m = 5 and a y-intercept at y = 3.

Answer 2

Answer:

Answer:

y= 5x + 3

Step-by-step explanation:

This is because you solve for slope, which is 5, then plug that into point slope form to get:

y - 8 = 5(x - 1)

y - 8 = 5x - 5

y = 5x + 3.

The manager of a public pool is counting the people who came to swim in June and July. There were 600 people who came in June. There were 800 people who came in July. What is the percent increase in people who came from June to July?25%

200%

3313%

75%

Answers

So,

The percent increase is basically the same as percent decrease except that you subtract the June count from the July count. If you let x be the June count and y be the July count, you can write it mathematically as follows:
$(y -x)/(x) = percent\ increase$

Substitute.
$(800 - 600)/(600) = percent\ increase$
$(200)/(600) \ or\ (1)/(3) = percent\ increase$

The percent increase in people from June to July is 33.3333333%, which is not one of the options you put there.

Which equation shows the substitution method being used to solve the system of linear equations?x + y = 6
x = y + 5

A.
x + y = y + 5

B.
x + (y + 5) = 6

C.
x = (x – 6) + 5

D.
(y + 5) + y = 6

Answers

The equation
(y + 5) + y = 6
shows the substitution method being used to solve the system of linear equations. So the correct option among all the options given in the question is option "D".
For a better explanation, let us first write down the two equations given in the question.
x + 5 = 6
and
x = y + 5
Now the thing that has been done is that the value of x in the first equation has been replaced by the value of x that is given in the second equation. this is actually the substitution method of solving equations.

Your answer is D. You're welcome ;-) (Not trying to sound sarcastic, just I wanted to say you're welcome now than never)

Write an equation in slope intercept form (-5,19) and (5,13) i got undefined but big ideas math won't let me type that how to i put in my answer?

Answers

The slope-intercept form is

$y = 16 - (3)/(5) x$

How you submit that in your onlie env. you have to figure out using the help of that system.

Take the general slope intercept form y = mx + b and fill in both coordinates:

19 = -5m + b

13 = 5m + b

If you add them, you get a new equation with only b:

32 = 2b, so b = 16

Next, you find m, for instance by putting b back into the 2nd formula:

13 = 5m + 16

-3 = 5m

m = -3/5

Now you have found b and m to have the slope-intercept form:

$y = 16 - (3)/(5) x$

Which melon has a greater mass , one that is 4 kilograms or one that is 4,100 grams ?

Answers

1 kilograms = 1000 grams
So, The melon which is 4100 grams has a greater mass since 4100 grams = 4.1 Kilograms and 4.1 kilograms is greater than 4 kilograms.

One that is 4,100 grams. A kilogram is 1,000 grams so 4 kilograms is 4,000 grams and 4,100 is bigger than 4,000 therefore 4,100 grams have more mass than 4 kilograms.
