Answer:
y = 10x - 5
Explanation:
The equation of the line has the general formula:
y = mx + c
where:
m is the slope = 10
c is the y-intercept = -5
Substitute with the givens in the above formula to get the equation as follows:
y = mx + c
y = 10x + (-5)
y = 10x - 5
Hope this helps :)
Answer: -10x+7.5
Step-by-step explanation:
First multiply -2.5(4x)= -10x and then -2.5x-3= 7.5 it should be -10x+7.5
Answer:
Red grapefruit costs more per pound.
Step-by-step explanation:
Red grapefruit
y =2x
This is in the form y= mx+b where m is the slope and b is the y intercept
The cost per pound is the slope, which is 2
The cost per pound is $2
Pink grapefruit
We need to find the slope
We have 2 points (0,0) and (4,4)
m = (y2-y1)/(x2-x1)
= (4-0)/(4-0)
=4/4
= 1
The slope is 1
The cost per pound is $1
Answer:
x = -2
y = -1
Step-by-step explanation:
2x+y = -5 so y = -5-2x
3x+2y = -8
substitute for y
3x+2(-5-2x) = -8
3x-10-4x = -8
-10-x = -8
add 10 to both sides
-10+10-x = -8+10
-x = 2
divide both sides by -1
-x/-1 = 2/-1
x = -2
y = -5-2(-2)
y = -5+4
y = -1
Step-by-step explanation:
given
900m = 2.700
m = 2.700 / 900
m = 0.003
