Write the slope-intercept form of the equation of each line given the slope and y-intercept.
6) Slope = -3, y-intercept = 3
7) Slope = -4, y-intercept = 5

Answer:

x = 5

Step-by-step explanation:

11x - 20 = 4x + 15

Add 20 to both sides

11x = 4x + 15 + 20

11x = 4x + 35

Subtract 4x from both sides

11x - 4x = 35

7x = 35

Divide both sides by 7

x = 35/7

x = 5

Step-by-step explanation:

Answer:

18) 3

20) -65

22) 12/5

24) -5/2

Step-by-step explanation:

18)  f(-5) = -[2(-5)+1] / 3

= -(-10+1)/3

= -(-9)/3

= 3

20) f(7) = -9(7)-2

= -63-2

= -65

22) f(-1) = -[(12 · -1)]÷5

= -(-12)÷5

= 12/5 or 2 2/5

24) f(9) = 2/9(9) - 9/2

= 2 - 9/2

= 4/2 - 9/2

= -5/2 or -2 1/2

Answer:

Step-by-step explanation:

Answer:

B. 30

Step-by-step explanation:

2m^2 + 12

m = 3

2(3)^2 + 12

3 squared is 9

2(9) + 12

2 times 9 is 18

18 + 12 = 30

2m^2 + 12 = 30

So we subtitute 3 to any "m" in your problem so,

2m^2+12

2(3)^2+12

2(9)+12

18+12

30

So,  B is the correct answer!

The value of the gift card declined by $37.40.

The total cost of all the items purchased has to be determined.

The sum of these items is $37.40

Change in value = value of the gift card - cost of items

$50 - $37.40 = $12.60

A similar question was answered here: https://brainly.com/question/19891026

Answer:

Total cost of pens = $1.57 x 1 = $1.57

Total cost of pencils = $1.98 x 2 = $3.96

Total cost of folders = $0.75 x 6 = $4.50

Total cost of highlighter: $3.45 x 1 = $3.45

Total cost of notebooks: $2.95 x 5 = $14.75

Total cost of binders: $3.55 x 2 = $7.10

Total cost of paper: $0.69 x 3 = $2.07

The sum of these items is $37.40

Change in value = value of the gift card - cost of items

$50 - $37.40 = $12.60

Answer:

x = 8 and y = 21

Step-by-step explanation:

3y + 27 = 90 so 3y = 90 -27 which is 63 and to get y you divide 63 by 3 to get 21

Angles on a straight line add up to 180 so 180 = x + 90 + 8x + 18

Then you minus 90 from 180 to get 90 = x + 8x + 18 which simplifies to 90 = 9x + 18

Then you minus 18 from 90to get 72 = 9x

Then divide 72 by 9 to get x = 8

Answer:

X = 2

equation x [tex]\leq[/tex] 2

Step-by-step explanation:

You Factor out the common term 2 which will look like [tex]\frac{2(2x+1)}{5} \leq 2[/tex]

You do this because if you multiply 2*2x and 2*1 you will get 4x+2

Now you will multiply 5 on both sides to turn it into an equation and not a fraction [tex](5)\frac{2(2x+1)}{5}\leq 2 (5)[/tex]

So you would cross out the 5 on the left and the 5 as the denominator to make this an equation and multiply 2 by 5 to get ten your equation will look like            [tex]2(2x+1)\leq 10[/tex]

So now that you have your equation you divide both sides by 2 [tex]\frac{2(2x+1)}{2} \leq \frac{10}{2}[/tex]

you cross out the 2 on the left and 2 as the denominator and divide 10 and 2 to get 5.         [tex]2x+1\leq 5[/tex]  

Now you subtract one from both sides    [tex]2x+1\leq 5\\-1=-1\\2x=4[/tex]

you'll get 2x=4

divide both sides by 2 to get x=2

To check you will insert 2 into the original equation [tex]\frac{4x+2}{5} \leq 2[/tex]

[tex]\frac{4(2)+2}{5} \leq 2 = \\\frac{10}{5} \leq 2=\\2\leq 2[/tex]

since the sign means less than or equal to 2 you can say that [tex]2\leq 2[/tex] is a correct inequality equation

x = 33°

Step-by-step explanation:

x = angle

a complement of an angle =(90-x)

x = (90-x) - 24

x = 90 - x - 24

x = 66 -x

2x = 66

x = 33

Answer:

9600400000000000 is in standard form

Answer:

Step-by-step explanation:

Think about how this question is written out mathematically.

5/36−x=8

You’re looking for x.

When rewritten, we can move x to the right side for a positive x, then we can move 8 over to the left side for -8.

53/6−8=x

In simple fraction form 8=8/1

But here's where we've got a problem. The denominators aren’t alike… 6≠16≠1

In this case, multiplying 8/1 by 6/6 is the easiest way to get a common denominator for both, 6.

Multiply both the numerator (8) and denominator (1) by 6. So, now we have 48/6

Now that we have common denominators, we can subtract.

53/6 - 48/6

= 5/6

To check:

53/6 - 5/6 = 48/6

48/6 = 8

You can follow the image attached. (Although not 100% accurate, since it is roughly an estimate of where the values are.)

Basically, you will indicate with dots (or crosses) the points which fulfill the data in the table. In this case, the x-axis will be the average temp and the y-axis will be the date in april trees bloom.

For example, you can roughly estimate where 1.5 in the x-axis, and follow to find 28 in the y-axis for the first set of data, and continue this for all 8 points.
