Slope of line perpendicular to ax+by=c is b/a
given
-2x-8y=18
slope of perpendicular is -8/-2=4
y=4x+b
find B
(4,5)
x=4,y=5
5=4(5)+b
5=20+b
minus 20
-15=b
y=4x-15

Answer:
19.32
Step-by-step explanation:
To find the missing number, we need to solve for the total of the left side of the equation.
Total = 8.4(1.5 + 2.3)
Total = 8.4(3.8)
Total = 31.92
Now we subtract the total to the only value on the right side.
Missing number = 31.9-12.6
Missing number = 19.32
8.4(1.5+2.3) = 12.6 + 19.32
Answer:
x+2y=-14x+2y=-14
x+14x+2y-2y=-14
15x+0=-14
15x=-14
15x/15=-14/15=-7/5
x=7/5.
Step-by-step explanation:
Before you start calculating the following . You need to group like terms .Also when you are moving the numbers to the other side and it is negative you need to change it to positive . Also when you are changing it to the other side and it is positive you need to change it to negative.Thank you for the question
