Answer:

y=2x+4

Step-by-step explanation:

the y intercept is 4, so you plug that into the equation, and since the line goes up 4 then over 2 so when you put rise over run, the slope is positive 2, which you can verify since the line is going up

*note, good job on figuring it out on your own. i know that you probably second guess your self, but 8 times out of 10, your instincts are correct

if you have any questions, leave them in the comments and i will try to answer them, if this helped, pls give brainliest

How do you solve 5/x=x-4

alexandr402 [8]

$\frac{5}{x}=x-4\\
x\not=0\\
5=x^2-4x\\
x^2-4x-5=0\\
x^2+x-5x-5=0\\
x(x+1)-5(x+1)=0\\
(x-5)(x+1)=0\\
x=5 \vee x=-1$

Answer:

x = 52

Step-by-step explanation:

∡RQS = 180 - (90 + 34)

∡RQS = 56°

∡PQS + ∡RQS = 180°

∡PQS = x + 72

x + 72 + 56 = 180

x + 128 = 180

x = 52

Solve for y: y^3+5y^2−9y−45=0

choli [55]

For this, I will be factoring by grouping to solve for y.

Firstly, factor y^3 + 5y^2 and -9y - 45 separately, Make sure that they have the same quantity on the inside:

$y^2(y+5)-9(y+5)=0$

Now you can rewrite it as $(y^2-9)(y+5)=0$ . However we are not finished factoring.

Now with y^2 - 9, we will apply the difference of squares rule, which is $x^2-y^2=(x+y)(x-y)$ . Apply it as such:

$(y+3)(y-3)(y+5)=0$

Now that it is completely factored, we can apply the Zero Product Property and solve for y:

$y+3=0\\y=-3\\\\y-3=0\\y=3\\\\y+5=0\\y=-5$

<u>In short, y = -5, -3, and 3.</u>
