Answer:

Point-slope form: y-4=2(x+1)

Slope intercept form: y=2x+6

Answer:

y-4=2(x+1)

Step-by-step explanation:

Point-slope form is equal to

y-y_1=m(x-x_1)

where y and y1 are the known y coordinates of two points on the line, and x and x1 are the known x coordinates of two points on the line. All we need now is m, which is the slope:

4-2=m(-1-(-2))

We can simplify negative one minus negative two as positive 1.

4-2=m(1)

4 minus 2 is 2, so m times 1 is 2. That means m is 2.

Now, we have the slope, so we can convert to point-slope form using one of the two points. Let's use (-1, 4). We can plug those values in for x1 and y1:

y-4=2(x+1)

Which expression is equivalent to (a^-3 b/a^-5 b3)^-3? Assume a=0, b=0.
prohojiy [21]
Use:\\\\\dfrac{a^n}{a^m}=a^{n-m}\\\\(a^n)^m=a^{nm}\\\\a^{-n}=\dfrac{1}{a^n}\\\\(ab)^n=a^nb^n

\left(\dfrac{a^{-3}b}{a^{-5}b^3}\right)^{-3}=\left(a^{-3-(-5)}b^{1-3}\right)^{-3}=\left(a^{-3+5}b^{-2}\right)^{-3}=\left(a^2b^{-2}\right)^{-3}\\\\=(a^2)^{-3}(b^{-2})^{-3}=a^{2(-3)}b^{-2(-3)}=a^{-6}b^6=\dfrac{b^6}{a^6}

8x+3&gt;_x+10 how do i solve dis<br> HELP
VashaNatasha [74]

Answer:

x > 1

Step-by-step explanation:

Subtract 3 from both sides

8x + 3 - 3 > x + 10 - 3

Simplify

8x > x + 7

Subtract x from both sides

8x - x > x + 7 - x

Simplify

7x - 7

Divide both sides by 7

7x/7 > 7/7

Simplify

x > 1

The linear relationship represented by the table has an initial value of 88 and a rate of change -6. Complete the table.
Nimfa-mama [501]
(2,88)
(6,64)
(9,46)
(15,10)
first find y=mx+b
88=-6(2)+b
b=100
y=-6x+100
then plug for y and solve for x or vise versa.
