Step-by-step explanation:
Y=x+1.25
Answer:
x = -3h
x = -12
Step-by-step explanation:
Given equation is 
To find the value of x in terms of h we will solve the expression to isolate x on one side of the equation.
by subtracting 1 from both the sides of the equation,
Multiplying 'h' on both the sides of the equation,
x = -3h
If h = 4,
x = (-3)(4)
x = -12
Answer:
Original Price = $23
Step-by-step explanation:
$5.75 is the price after a discount of 75%
Let the original price be x and x is 100% of the price
5.75 = 100%x - 75%x
5.75 = 25%x
The new price is 25% of the original because you are subtracting 75%
25% is also written as 0.25
5.75 = 0.25x
x = 5.75/0.25
x = 23
The original price is 23

you know that y=mx +c then in the place of m is 3 then answe is also three.
Ok, so the best way to start off solving this would be to find the y intercept.
The y intercept is the point that y is on when x is at 0
So when x (the horizontal axis, left to right) is at 0 the y axis (vertical axis, top to bottom) is at 3
That gives this equation a y intercept of 3, and because it is positive it will be plus 3
next we'll solve for the slope, the slope can be found using them formula (y2-y1)/(x2-x1)
We can use any two points on the line. So we'll use the points; (0,3) and (2,4)
So we plug these points into the equation, and the equation looks like...
(4-3)/(2-0)
So 4-3= 1
and 2-0=2
We set the slope up in rise (y) over run (x)
So the slope is 1/2
1/2 is equivalent to half.
So the slope of the line is .5x or 1/2x
with a y intercept of 3
So the equation would look like
y=.5x+3
or
y=1/2x+3
Answer choice C matches the equation that we got.
So your answer is C
