Y=8x-4 find y and x intercept

dlinn [17]

Answer:

<h3>The x intercept is 1/2</h3><h3>The y intercept is - 4</h3>

Step-by-step explanation:

y = 8x - 4

First to find the y intercept let x = 0

Substitute the value of x into the equation

That's

y = 8(0) - 4

y = - 4

<h3>The y intercept is - 4</h3>

To find the x intercept let y = 0

Substitute the value of y into the equation

that's

8x - 4 = 0

8x = 4

Divide both sides by 8

x = 1/2

<h3>The x intercept is 1/2</h3>

Hope this helps you

Through :(4,2),parallel to y =-3/4x-5<br> Solve for y

alex41 [277]

Answer:

y = $\frac{ - 3}{4}$ x + 5

Step-by-step explanation:

The Line equation is:

y = $\frac{- 3}{4} x - 5$

The line equation is in the form of y = m x + c

Slop of this line is (m1) = $\frac{ - 3}{4}$

Let another line with slop (m2) , passes through point (4 , 2)

As per question the another line is parallel to the given line equation

So, slop of both the lines are equal

∴ (m2) = (m1) = $\frac{ - 3}{4}$

Hence equation of another line with slop $\frac{ - 3}{4}$ and passing through points ( 4 , 2) is

y - y1 = (m2) (y - x1)

I.e y - 2 = $\frac{ - 3}{4}$ (x - 4)

Or, $4\times (y -2) = (- 3)\times (x - 4)$

Or , 4y - 8 = -3x + 12

Or, 4y = -3x + 12 + 8

Or , 4y = -3x + 20

∴ y = $\frac{ - 3}{4}$ x + 5

Hence The value of y = $\frac{ - 3}{4}$ x + 5 Answer

If x + 4=12,then x =8

anastassius [24]

Answer:

yes

Step-by-step explanation:

y + 4 = 12

Subtract 4 on both sides,

y + 4 - 4 = 12 - 4

y = 8

Given that f(x) = x2 + 5x + 6 and g(x) = x + 2, find (fºg)(x) and

PolarNik [594]

Answer:

$(f\circ g)(x)=x^2+9x+20$

Step-by-step explanation:

We have the two functions:

$f(x)=x^2+5x+6\text{ and } g(x)=x+2$

And we want to find:

$(f\circ g)(x)$

This is equivalent to:

$(f\circ g)(x)=f(g(x))$

Therefore, we will have:

$f(x+2)$

By substitution:

$f(x+2)=(x+2)^2+5(x+2)+6$

Simplify. Square and distribute:

$f(x+2)=(x^2+4x+4)+(5x+10)+6$

Rearrange:

$f(x+2)=(x^2)+(4x+5x)+(4+10+6)$

Combine like terms:

$f(x+2)=(f\circ g)(x)=x^2+9x+20$
