The answer is D.
Adding 19 to both 2 & 5 in 2/5 will equal 21/24. 21/24 can then be simplified to 7/8.
Answer:
x = plus or minus √7
Step-by-step explanation:
Solve the equation 7x^2=49, starting out by dividing both sides by 7. This results in x^2 = 7.
We need to solve for (isolate) x. To do this, take the square root of both sides:
x = plus or minus √7
Answer:
y = 2x - 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = ![\frac{y_{2}-y_{1} }{x_{2}-x_{1} }](https://tex.z-dn.net/?f=%5Cfrac%7By_%7B2%7D-y_%7B1%7D%20%20%7D%7Bx_%7B2%7D-x_%7B1%7D%20%20%7D)
with (x₁, y₁ ) = (- 1, - 10) and (x₂, y₂ ) = (5, 2)
m =
=
=
= 2 , then
y = 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (5, 2 ) , then
2 = 10 + c ⇒ c = 2 - 10 = - 8
y = 2x - 8 ← equation of line
