The answer is A. Y=2x+2
Because the slope is 2 and it crosses the Y axis at 2

Mario got a part time job mowing lawns. On Monday he charged his neighbor $25 to mow his lawn, then spent $6 to refill his lawn

ss7ja [257]

Answer:

Step-by-step explanation:

Step one:

He charged $25 and spent $6 on gas on Monday.

then he made 25-6= $19 mowing his neighbor's lawn.

the next day is Tuesday(we are not told he spent any amount on gas on Tuesday).

So he mowed his Grandparents yard for $20.

total money saved for Monday and Tuesday is

19+20= $39

<u>Hence he has $39 for mowing both yards</u>

Part of the roof of a factory is devoted to mechanical support and part to green space. The area G that is designated as green s

alexgriva [62]

Answer:

Therefore, the area of green space would be 30 square yards.

Step-by-step explanation:

The area G that is designated as green space can be modeled by the polynomial $2x^2-7x$

the area M that is devoted to mechanical support can be modeled by the polynomial $x^2-9x+24.$

We are asked to find the area of the green space, when area of roof (R) is 36 square yards.

The area of roof would be equal to sum of areas of green space and mechanical support.

$R=G+M$

$G = 2x^2 -7x M = x^2 -9x +24$

the total area is given by 36 yd^2. And we know that:

$R = 36 yd^2 = G+M$

Replacing the info given we got:

$36 = 2x^2 -7x +x^2 -9x +24\\\\ 12= 3x^2 -16 x$

And we can rewrite this expression like this:

$3x^2 -16 x -12 =0$

And we can use the quadratic formual to solve this problem:

$X =\frac{-b \pm \sqrt{b^2 -4ac}}{2a}$

With a = 3, b = -16 , c =-12. Replacing we have

$x = \frac{16 \pm \sqrt{(-16)^2 -4*(3)*(-12)}}{2*3}$

And the solutions for this case are:

Since length cannot be negative, therefore, the value of x would be 6.

The area of green space would be:

x = 6

$2x^2-7x\Rightarrow 2(6)^2-7(6)\\\\2x^2-7x=2(36)-42\\\\2x^2-7x=72-42\\\\2x^2-7x=30$

the area of green space would be 30 square yards.

Answer: 2/5 is closer 1/2. and it is easy to find half of 7 mentally. Half of 7 is 3.5, so Martin gave away about 3.5 pounds away.

Factorise x squared + 12 x + 35

Ksenya-84 [330]

5 and 7 add to make 12 and multiply to make 35 so those are the numbers that will be used:
(x+5)(x+7)

Hope this helps :)
