Answer:

The first graph represents y<2x-3

For this use some values for x e.g

X= 2 2(2)-3=y=1

So when x is 2 y is 1 so search for the graph that crosses the coordinate (2,1)

${\huge{\boxed{\sf{Question}}$

$-1.2= y\div2.4 -1.7$

Solve for y

${\huge{\boxed{\sf{Answer\:with\:explanation }}}$

let's put our equation first

$-1.2= y\div2.4 -1.7$

Flip the equation

$y\div2.4-1.7=-1.2$

Now follow the rule of $BOMDAS/PEMDAS$

$y\div2.4-1.7=-1.2$

${\underline{simplify}}$

$0.416667y-1.7=-1.2$

add $1.7$ to both sides

$0.416667y=0.5$

Divide both sides by $0.416667$

$y=1.2$

${\huge{\boxed{\sf{Answer}}}$

$y$ would equal $1.2$

If neither a nor b are equal to zero, which answer most accurately describes the product of (a + bi)(a - bi)?

Scrat [10]

Answer: the correct option is

(D) The imaginary part is zero.

Step-by-step explanation: Given that neither a nor b are equal to zero.

We are to select the correct statement that accurately describes the following product :

$P=(a+bi)(a-bi)~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

We will be using the following formula :

$(x+y)(x-y)=x^2-y^2.$

From product (i), we get

$P\\\\=(a+bi)(a-bi)\\\\=a^2-(bi)^2\\\\=a^2-b^2i^2\\\\=a^2-b^2\times (-1)~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~[\textup{since }i^2=-1]\\\\=a^2+b^2.$

So, there is no imaginary part in the given product.

Thus, the correct option is

(D) The imaginary part is zero.

Answer:

- Point of intersection = (4, 360)

- The meaning of the intersection (4,360) means that when 4 hours of repair has passed for either service, the price of each service will be the same ($360).

- If it takes 3 hours to fix your car: Amy's Auto Repair will be the cheapest of the two services.

Step-by-step explanation:

Set both functions equal to each other:

100+65x = 40+80x

Subtract from both sides:

65x-80x = -15x

40-100 = -60

Set the two new numbers equal to each other:

-15x = -60

Solve this equation:

-60 / -15 = 4

This means the answer to the x intercept is 4.

...Now we need to find the y intercept...

To figure this out, you need to substitute the x-intercept (4) in for any x in the equation:

100+65(4) = 40+80(4)... simplify... 100+260 = 40+320

Now solve this:

100+260 = 360 --- and --- 40+320 = 360...

360 = 360...this means the y-intercept is 360.

So, the answer to question 1 is (4,360)

Why Amy's Auto Repair shop will be cheaper than Mike's Repair Shop after 3 hours of service:

3 hours of Mike's service: 100+65(3) = $295

3 hours of Amy's service: 40+80(3) = $280 - CHEAPER

I hope this helps :)
