Ray and Claudia are writing in journals. Ray has written 16 pages and he now writes 2 pages every day. Claudia has written only
balu736 [363]

Answer:

6 days

Step-by-step explanation:

Step one:

Given data

For Ray

He has 16 pages already

Now he is writing 2 pages per day

let x be the number of days

and y be the total number of pages writen

the linear function for the situation is given as

y=2x+16-------------1

For Claudia

He has 2 pages already

Now he is writing 4 pages per day

let x be the number of days

and y be the total number of pages writen

the linear function for the situation is given as

y=4x+2-------------2

Step two:

let us equate equation 1 and 2 to find x

2x+16=4x+2

collect like terms

2x-4x=2-16

-2x=-12

divide both sides by -2

x=12/2

x=6

Therefore it will take 6 days for them to have the same number of pages

Which statements must be true about the image of ΔMNP after a reflection across Line E G? Select three options. The image will b
masya89 [10]

Answer:

The image will be congruent to ΔMNP.

Line EG will be perpendicular to the line segments connecting the corresponding vertices.

The line segments connecting corresponding vertices will all be parallel to each other.

Step-by-step explanation:

The reflected image will be the mirror image of ΔMNP, so it will be congruent.  The lines connecting each vertex to the corresponding vertex will be parallel, and all three lines are perpendicular to EG.

Which of the following is a polynomial with roots 5,7 and -8
Aloiza [94]

The idea is to use the zero product property in reverse to go from the roots to the factorization. Then you expand out the polynomial using the distributive property.

x = 5 or x = 7 or x = -8

x-5 = 0 or x-7 = 0 or x+8 = 0

(x-5)(x-7)(x+8) = 0

(x-5)(x^2+x-56) = 0

x(x^2+x-56) - 5(x^2+x-56) = 0

x^3+x^2-56x  -5x^2-5x+280 = 0

x^3-4x^2-61x+280 = 0

f(x) = x^3 - 4x^2 - 61x + 280

<h3>Answer: Choice D</h3>
