Let the son's age be x and man be y

y=26+x

y=8+3x

x=9

Answer:

Hey there!

Let the son's age be x.

Thus, the man's age is x+26, and can also be represented by 3x+8.

x+26=3x+8

x+18=3x

18=2x

x=9

The son is nine years old.

Hope this helps :)

Write the equation of the parabola that has its x-intercepts at (1+<img src="https://tex.z-dn.net/?f=%5Csqrt%7B5%7D" id="TexForm

VladimirAG [237]

Answer:

$y=2x^2-4x-8$

Step-by-step explanation:

<u>Factored form of a parabola</u>

$y=a(x-p)(x-q)$

where:

p and q are the x-intercepts.
a is some constant.

Given x-intercepts:

(1+√5, 0)
(1-√5, 0)

Therefore:

$\implies y=a(x-(1+\sqrt{5}))(x-(1-\sqrt{5}))$

$\implies y=a(x-1-\sqrt{5})(x-1+\sqrt{5})$

To find a, substitute the given point (4, 8) into the equation and solve for a:

$\implies a(4-1-\sqrt{5})(4-1+\sqrt{5})=8$

$\implies a(3-\sqrt{5})(3+\sqrt{5})=8$

$\implies4a=8$

$\implies a=2$

Therefore, the equation of the parabola in factored form is:

$\implies y=2(x-1-\sqrt{5})(x-1+\sqrt{5})$

Expand so that the equation is in standard form:

$\implies y=2(x^2-x+\sqrt{5}x-x+1-\sqrt{5}-\sqrt{5}x+\sqrt{5}-5)$

$\implies y=2(x^2-x-x+\sqrt{5}x-\sqrt{5}x+\sqrt{5}-\sqrt{5}+1-5)$

$\implies y=2(x^2-2x-4)$

$\implies y=2x^2-4x-8$

What would -2 - (-7) be? And how would you do that

zavuch27 [327]

Answer:

Step-by-step explanation:

Okay, so adding negative numbers can get very tricky, but I think I can help

Since there are two negative signs next to each other, they both cancel out and become positive so instead you get

-2+7

And if you do this with a number line, if you start and negative 2 and keep going right 7 times, you get 5

I hope I helped! I know negative numbers can be really difficult, but once you get the hang of it I bet you'll be great!
