Answer:

Step-by-step explanation:

Slope = (y2-y1)/(x2-x1) = (9+6)/(-8-1) = -15/9

= -5/3

Answer:

y = $100 + $1.50x

y = $15x

Step-by-step explanation:

Given that :

A Wok in the Park charges :

Setup fee =$100 ; per person = $12.50

Chop Chop Catering charges :

$15 per person

Writing equation for the amount charged by the 2 services in the form :

y = mx + c ;

A Wok in the Park ;

Setup fee =$100 = c = intercept ; per person = $12.50 = slope = m

y = $100 + $1.50x

Where x = number of persons. ; y = amount charged

Chop Chop Catering charges :

$15 per person

y = 0 + $15x

y = $15x

x = number of persons. ; y = amount charged ; intercept (c) = $0

Answer:

Step-by-step explanation:y=1/4 X +6

Answer:

y= 1/4x+ 6

Step-by-step explanation:

Because the line intersects the y-axis at 6, we know the y-intercept, b, is 6.

By counting, we can see the line rises 1 unit for every 4 units it runs to the right. So, the slope, m, of the line is 1/4.

Substitute m and b into the slope-intercept equation, y = mx + b. The equation of the line is y = 1/4 x + 6.

Answer:

It cost $397

Step-by-step explanation:

Because 906 divided by 2 equals 453 minus 56 equals 397

Answer:

x > 2

Step-by-step explanation:

The required inequality to represent “a number is at most two” is x ≤ 2.

Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
The expression of a number is at most two, implying that a number cannot be more than 2.
So the inequality that best represents the scenario is given as x ≤ 2.

Thus, the required inequality to represent “a number is at most two” is x ≤ 2.

Answer:

1/27 is the answer..... .......

Answer:

14

Step-by-step explanation:

28m + 21 = 413

28m = 413 - 21

        = 392

m = 392/28

   = 14

Therefore m is 14 :)

Answer:

14

Step-by-step explanation:

28m+21=413

Subtract both sides by 21

28m=413-21

28m=392

m=14

Answer:

No solutions

Step-by-step explanation:

6x+2y=20

-3x-y=-4 (by rewriting)

So

6/-3 = 2/-1≠20/-4

-2=-2≠-5

So it has no solutions

Answer:

He actually has 25 paints.

Step-by-step explanation:

This is because you take 18x100(100 is the total % under 72 because 72 is out of 100) that equals 1800. then, you take 1800 and divide it by 72. That is because 72 is the actual number that we already have. You would get 25 after dividing. hope this helps:)

Answer:

25

Step-by-step explanation:

Think the number is x

So

According to the question

The equation is

x×72%=18

x×72/100=18

x×18/25=18

x=18×25/18

x=25

So

There are 25 colours on the artist's palette

Answer:

Tuscon. btw DIE MAX!

Step-by-step explanation:

Answer:yo the rule is

R% x P x T

which in this question is:

r%= 9%

p= 630

t=8

so

630 x 8 x 9% = 453.6

that's the final answer and in order to make sure make

630+453.6=1083.6

Answer:

x = [tex]\frac{15}{2}[/tex]

Step-by-step explanation:

Given

[tex]\frac{4x-1}{2}[/tex] = x + 7 ( multiply both sides by 2 to clear the fraction )

4x - 1 = 2(x + 7) ← distribute

4x - 1 = 2x + 14 ( subtract 2x from both sides )

2x - 1 = 14 ( add 1 to both sides )

2x = 15 ( divide both sides by 2 )

x = [tex]\frac{15}{2}[/tex]
