Write the equation given the point 4,2 and slope 1/2

raketka [301]

Hello.

We have a point that the line passes through and its slope.

Let's write the equation in Point-Slope Form:

y-y₁=m(x-x₁)

In this case,

y₁=2

m= $\displaystyle\frac{1}{2}$

x₁=4

Plug in the values:

$\mathrm{y-2=\displaystyle\frac{1}{2} (x-4)}$

This is point-slope form. Now, what about Slope-Intercept?

First, we should distribute $\displaystyle\frac{1}{2}$ :

$\mathrm{y-2=\displaystyle\frac{1}{2} x-2}$

Add 2 to both sides:

$\mathrm{y=\displaystyle\frac{1}{2} x-2+2}$

Simplify:

$\mathrm{y=\displaystyle\frac{1}{2} x}$

I hope it helps.

Have a nice day.

Solve this inequality: j/4 – 8 < 4. A. j < –48 B. j < 48 C. j > –12 D. j < 12

Kruka [31]

$\frac{j}{4} - 8 \ \textless \ 4 \\ \\ \frac{j}{4} \ \textless \ 4 + 8 \\ \\ \frac{j}{4} \ \textless \ 12 \\ \\ j \ \textless \ 12 \times 4 \\ \\ j \ \textless \ 48 \\ \\$

The final result is: j < 48.

Solve for x in the equation x^2 + 2x+ 1 = 17.

muminat

Answer:

first, subtract 17 on both sides: x²+2x-16=0

this cannot be factored, so use the quadratic formula to solve for x:

b²-4ac=2²-4(10(-16)=4+64=68

√68=2√17

so x=(-2+2√17)/2 or x=(-2-2√17)/2

x=-1+√17 or x=-1-√17

The expression 2y + 2.7 is equal to for y = 4.

Darya [45]

Answer:

10.7

Step-by-step explanation:

i am not certain but since y is the 4 you will have 2(4) + 2.7 so you get 8+2.7 since you do 2x4 then you add 8 and 2.7 to get 10.7
