Let's convert the given equation into slope - intercept form :

  • 2x + 5y =  - 20

  • 5y =   - 20 - 2x

  • y =  \dfrac{ - 20 - 2x}{5}

  • y =  \dfrac{ - 20}{5}  -  \dfrac{2x}{5}

  • y =  - 4 -  \dfrac{2x}{5}

  • y =  -  \dfrac{2}{5} x - 4

So, here y - intercept (c) = -4

Plisss help on my assesment
Anon25 [30]

Answer:

The first one is equivalent [the 6x+48 = 2(3x+24)] and the second one is <u>NOT</u> equivalent [the 7x+21 ≠ 2(5x+3)]

Step-by-step explanation:

Just follow distributive property to solve these. You can ignore the first expression in both until you have to compare the answers.

1. 6x+48 and 2(3x+24)

2(3x+24) ---> 2(3x) + 2(24) ---> <u>6x + 48</u>

Bring in the first expression ~ <u>6x+48 and 6x+48 </u>

They are the same, so they are equivalent

2. 7x+21 and 2(5x+3)

2(5x+3) ---> 2(5x) + 2(3) ----> 10x + 6

Bring in the first expression ~ <u>7x+21 and 10x + 6</u>

They are NOT the same, so they are NOT equivalent

Find two numbers whose sum is 64 and whose difference is 42
vovangra [49]
These numbers are  "a"  and "b".  
Sum is 64,  so  a+b=64
Difference  is 42  so  a-b=42
So you've got:
+\begin{cases} a+b=64 \\ a-b=42\end{cases} \\ \overline{, \quad2a \quad \ = \ 106} \qquad /:2 \\ a=53
When a+b=64 and a=53  you've got:
53+b=64
b=11

So these numbers is 53 and 11.

Gus spends 12% of his monthly income on entertainment. He constructs a circle graph to illustrate his budget. What is the degree
Lapatulllka [165]

Answer:

43.2°

Step-by-step explanation:

Just multiply .12 by 360° (the number of degrees in a circle), this will give you the central angle.

Multiplying the decimal means your finding 12.% of 360°

So the angle is 43.2° degrees
