Answer:
He'll have $195 left
Step-by-step explanation:
$35 x 3 = $105
$300 - $105 = $195
To find the gradient of a line we first hv to find the formula
so Gradient=√X1-x2and √y1-y2
((-2,1) and (0,-5)) line 1
line 2(0,-1) and (1,0)
first we will work for line 1
X1 is -2
X2 is -0
Y1 is 1
Y2 is -1
so y=x-1
so we substitute the values
1--1=-2--0
so,
1+1=-2+0
2=-2
-0
So the equation 1 line 1 is not true
we will now go to equation 2 line 2
the equation is 3x+y=-5
we substitute the values
3(-2--0)+1--1=-5
3(-2)+-2=-5
-6+-2=-5
-8= -5
group like terms
Ur answer should look like this -3
So the answer is 3x+y=-5
Answer:
The red will cost him more by $2.21
Step-by-step explanation:
First you multiply the amount of gallons of grey paint and the cost and you get 24.59 x 3= 73.77
The do the same for red
37.99 x 2= 75.98
the red is going to cost him more by 75.98-73.77= $2.21
