Answer:
49b^10 -16b^2
Step-by-step explanation:
(7b^5)^2 -(4b)^2=
49b^10 - (4b)^2=
49b^10 - 16b^2
Answer:
y=2/7x+9
Step-by-step explanation:
Slope-intercept form is written y=mx+b.
y= also known as f(x), and is always by itself in slope-intercept form.
m= the slope.
x= the variable written to the right of the slope.
b= the y-intercept.
We know that the slope is 2/7 and the y-intercept in the equation is 9. Therefore, we can plug these numbers into the equation. So...
y=2/7x+9
is the correct equation written in slope-intercept form.
Hope this helps!! Have an amazing day (^人^)
Answer:
Step-by-step explanation:
x = y - 2.........(1)
4x + y = 2......(2)
Substituting x in (1) in (2)
4(y - 2) + y = 2
4y - 8 + y = 2
5y = 2 + 8
5y = 10
y = 10/5
y = 2
Putting x in (1)
x = y - 2
x = 2 - 2
x = 0
Answer:
y=3x+10
Step-by-step explanation:
First, put the equation into point-slope form.
y-y1=m(x-x1)
y-4=3(x+2)
Next, distribute 3 to (x+2) and simplify.
y-4=3x+6
y=3x+10
Answer:
4
Step-by-step explanation:
We can see from the two marked points the coordinates are: (2, 8) and (4, 16)
That means the rise (vertical change) is 16 - 8 = 8 units. And the run (horizontal change) is (4 - 2) = 2 units.
Therefore slope = rise/run = 8/2 = 4.
