What’s the answer in simplified form

Mathematics
1 answer:
Schach [20]3 years ago
3 0

Answer:

Step-by-step explanation:

To solve this correctly, you need to make sure to distribute the negative onto both terms in the second parentheses.

So fully expanded, the problem would be:

2y² + 8y -7 + 3y - 3 = ?

You can easily rearrange the terms, or just do it in your head!

It would become:

2y² + 8y +3y -7 -3

= 2y² + 11y -10

Make sure you keep the terms with different variables separate! I hope this is helpful!

9. Krista and Emily wrote an equation of a line that is parallel to the line y = 3x - 1 and passing
Andre45 [30]

Step-by-step explanation:

Hey there!

The equation, of a st. line that passes through point (5,9) is,

(y - y1) = m1(y - y1)

Put the values,

(y - 9) = m1(x - 5)

It is 1st equation.

Now, another equation is,

y = 3x-1.........(ii)

Comparing the equation with y = mx+c.

Slope (m2)= 3

As per the parallel lines,

m1=m2=3

Putting,

the value of m1 in equation(i)

(y-9)= 3(x-5)

y-9= 3x - 15

y = 3x - 6.

So, Krista equation is correct.

lubasha [3.4K]

The equation that can be used to represent Diego's and Lin's savings account is 250 = 40 + 6x and Total savings= 100 + 50x respectively.

<h3>How to write equation</h3>

let

  • x = amount added each month

Diego:

6 months ago = $40

Now = $250

250 = 40 + 6x

250 - 40 = 6x

210 = 6x

x = 210/6

x = $35

Lin:

Now = $100

Future = $50 per month

let

  • x = number of months

Total savings= 100 + 50x
