Qu2.05 ML<br> Solve for x: 5|2x - 2] + 8 = 18.

Luda [366]

Answer:

512x−2+8=18

Step 1: Simplify both sides of the equation.

512x−2+8=18

512x+−2+8=18

(512x)+(−2+8)=18(Combine Like Terms)

512x+6=18

Step 2: Subtract 6 from both sides.

512x+6−6=18−6

512x=12

Step 3: Divide both sides by 512.

512x512=12/512

What is the equation of the line that passes through the point (-5,2) and has a slope of 4/5

dedylja [7]

Answer:

4x - 5y + 30 = 0

Step-by-step explanation:

When a slope of a line and a point passing through it is given then we use slope - one point form to determine the equation of the line.

It is given by:

$(y - y_1) = m (x - x_1)$

where $m$ is the slope of the line and

$(x_1, y_1)$ is the point passing through it.

Here $m = \frac{4}{5}$ and $(x_1 , y_1) = (-5,2)$ .

Substituting in the equation we get

$(y - 2) = \frac{4}{5} (x + 5)$

$\implies 5y - 10 = 4x + 20$

$\implies 4x - 5y + 30 = 0$

Let f(x) = x2 − 8x + 5. Find f(−1)

rewona [7]

Answer:

Step-by-step explanation:

$f(x)=x^2-8x+5$

now substitute x for -1

$f(-1)=(-1)^2-8(-1)+5$

now solve

$f(-1)=1+8+5$

$f(-1)=14$

there is your answer! hope this helps! :)
