Answer:
y=2x+2
Step-by-step explanation:
Answer: y = 2x
Step-by-step explanation:
y=mx+b
m is the slope. so if the slope is 2 we can fill in 2 for m.
y = 2x + b
now we are going to plug in the point they gave us (1, 2) to find b.
1 is the x coordinate of the point and 2 is the y coordinate. so we put 1 in for x and 2 in for y.
2 = 2(1) + b
2 = 2 + b
b = 0
so our equation is y = 2x + 0, or y = 2x

“A Wok in the Park” charges a $100 set-up fee plus $12.50 per person. “Chop Chop Catering” charges $15 dollars per person.
Write a equation in the form y=mx+b for both companies
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
A gallon of gasoline cost $3.00 last year, and now costs 5% more. What is the cost of a gallon of gasoline now?
a) 4.50
b) 3.15
c) 3.05
Answer:
B
Step-by-step explanation:
We know that Last year one gallon costs $3.00
and we also know that it costs %5 more this year.
We know that %100 is always the same which is $3.00
Then since we know $3.00 is %100, we can add %5 to %100 to get %105.
Then you multiply 105/100 by 3 then you will get 3.15 which is what B is
So that means our answer is B

Mark drew a line to fit the data in a scatter plot as shown What is the equation of the line that Mark drew?
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.

(4x-1) /2=x+7
4x-1 all over 2 = x +7
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]

Write an inequality to
represent “a number is at
most two”
Answer:
x > 2
Step-by-step explanation:
The required inequality to represent “a number is at most two” is x ≤ 2.
What is inequality?Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
What are equation models?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.

solve 28m+21=413 thanks!
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
David wants to buy a new tablet computer. He looks at a sales ad and sees that a computer store is selling a tablet computer for $499 which is 1/3 off the regular price.
Part A:
Write an equation that represents the situation. Let x = the original cost of the tablet.
Part B:
Find the original cost of the tablet computer.
Answer:
Part A: x÷3=$499
Part B: $1497
Step-by-step explanation:
A: Because to find a fraction of somthing we have to divide, so in this case we divided the original price by 3 to get $499.
B:To find the original price we have to multiply the one third of it ($499) by 3 to get the original amount.
