Write the equation in slope intercept form y+4=-(x-7)/ Please help I don't get this and I have a final on thursday.​
frez [133]

Answer:

y=-x+3

Step-by-step explanation:

we have

y+4=-(x-7)

This is the equation of the line in point slope form

The equation of the line in slope intercept form is equal to

y=mx+b

where

m is the slope

b is the y-intercept

Convert the equation to slope intercept form

remove the parenthesis right side

y+4=-x+7

subtract 4 both sides

y+4-4=-x+7-4

y=-x+3 ---> equation in slope intercept form

HELP ME NOWWWWWW LIKE JUST GIVE ME THE ANSWER PLEASEEEEE
Minchanka [31]

Answer:

$997

Step-by-step explanation:

Okay, so the first thing you need to do is find how much commission Luis received so that we can add that to the base salary. To do that, we could set up a proportion.

Since percentages are out of 100, we'll need to put 14 over 100. Because $6050 is the total amount he sold, we'll put that number in the denominator corresponding to the total, or 100. The proportion will look somewhat like the following:

\frac{14}{100} =\frac{x}{6050}

To find X, we have to multiply across (14 × 6050, which is 84700) then divide that by 100 (or the denominator right on the other side), which would result in 847.

So... X = $847. Now we add that to the base salary (150 + 847), and that gets us $997 for the total he was paid last week.

I apologize for taking so long to help ^-^;

Which of the following equations has a slope of -2 and passes through the point (2,3)?
ryzh [129]

Option C (Same as Option D)

<h2>Explanation:</h2>

Option C and D are the same, so I'll assume you made a mistake when writing this question. However, let's figure out which of the following equations has a slope of -2 and passes through the point (2,3):

A. y = -2x + 6

B. y - 3 = -2(x + 2)

C. y = -2x + 7

<em />

<em>All these equations have a slope of -2.</em>

FROM OPTION A:

Recall \ our \ point \ is \ (2,3), \ so: \\ \\ x=2 \\ \\ y=3 \\ \\ Substituting \ into \ the \ equation: \\ \\ 3=-2(2)+6 \\ \\ 3=-4+6 \\ \\ 3=2 \ False!

Since 3\neq 2 then the line doesn't pass through the point (2, 3)

FROM OPTION B:

Recall \ our \ point \ is \ (2,3), \ so: \\ \\ x=2 \\ \\ y=3 \\ \\ Substituting \ into \ the \ equation: \\ \\ 3-3=-2((2)+2) \\ \\ 0=-2(4) \\ \\ 0=-8 \ False!

Since 0\neq -8 then the line doesn't pass through the point (2, 3)

FROM OPTION C:

Recall \ our \ point \ is \ (2,3), \ so: \\ \\ x=2 \\ \\ y=3 \\ \\ Substituting \ into \ the \ equation: \\ \\ 3=-2(2)+7 \\ \\ 3=-4+7 \\ \\ 3=3 \ True!

Since 3\neq 3 then the line passes through the point (2, 3)

<em>Finally, the equation that has a slope of -2 and passes through the point (2,3) is Option C (Same as Option D)</em>

The ratio of a rectangle's length to its width is 4:3. If the length of the rectangle is 48 inches, what is the perimeter of the
Andrei [34K]

Answer:

36 inches

Step-by-step explanation:

The ratio is L:W = 4:3 = 48:?

if you divide 48 by 4 you get 12. So now do 12 times 3 to get 36! Whatever you do to one ration do the same to the other, I like to remember it that way.
