Answer:
-8/5
Step-by-step explanation:
When you solve for y, the slope of the line is the x-coefficient. For the given line, that is ...
8y = 5x +11 . . . . . add 5x
y = 5/8x +11/8 . . . . divide by 8
The given line has a slope of 5/8. The perpendicular line will have a slope that is the opposite of the reciprocal of this:
-1/(5/8) = -8/5 . . . . slope of perpendicular line
Answer:38x-34
Step-by-step explanation:
f(x)=x^2+3x-7
g(x)=5x-3
We multiply the entire F equation times two, (x^2+3x-7)*4=
(4x^2+12x-28)
Now the entire g equation by 2, (5x-3)*2
(10x-6)
Now we add both equation
(4x^2+12x-28)+(10x-6)
(4x^2+22x-34)
(4x*4x+22x-34)
(16x+22x-34)
38x-34
Hopefully this is correct :)))
Answer:
using the given points substitute it into the equation y=mx+c
therefore
y=4
m=-2/3
X=6
c=?
so we should c=intercept
Step-by-step explanation:
y=mx+c
4=-2/3(6)+c
4=-4+c
c=4+4=8
therefore equation of the graph is y=-2/3X+8
The width of the sidewalk would be 10ft.
Sorry if incorrect
Answer:
Jack is 8
Step-by-step explanation:
j= jacks age
2j+5 =21
This is the equation from Twice jacks age plus five is 21
We want to isolate j
Subtract 5 from each side
2j+5 =21
2j+5-5 = 21-5
2j = 16
Divide by 2
2j/2 =16/2
j =8
