What are the intercepts of y=4x-2

Lemur [1.5K]

Answer:

To find the x-intercept, make y equal to zero, and solve for x. To find the y-intercept, make x equal to zero, and solve for y.

Explanation:

<span>y=4x−2</span>

<span>
</span>

X-Intercept

<span>0=4x−2</span>

<span>
</span>

Add 2 to both sides of the equation.

<span>2=4x</span>

<span>
</span>

Divide both sides by 4.

<span><span>2/4</span>=x</span>

<span>
</span>

Simplify.

<span><span>1/2</span>=x</span>

</span>

Switch sides.

<span>x=<span>1/2</span></span>

there are four semi trailer trucks parked in a line at the rest stop after the first truck each truck in the line weighs 2 tons

alexira [117]

Call the weght of the first truck " $w_{1}$ ". We then know that the truck after that is 2 tons more, and the next and the next. i.e:
$w_{2} = w_{1} + 2$
$w_{3} = (w_{2} + 2) = (w_{1}+4)$
$w_{4} = (w_{3} + 2) = (w_{1}+6)$

We also know that total is 32 tons.
$w_{total} = 32 = (w_{1}) + (w_{2}) + (w_{3}) + (w_{4})$
$32 = (w_{1})+(w_{1}+2)+(w_{1}+4)+(w_{1}+6)$
$32= 4(w_{1})+12$
$20=4(w_{1})$
$w_{1} = 5 tons$

Therefore the trukcs weigh 5,7,9 and 11 tons for a total of 32 tons.

Converting to pounds, the trucks weigh 10,000, 14,0000, 18,0000 and 22,000 pounds.
