Answer:

Yes you are right.

The answer is .45 or 45/100 which reduces to 9/20.

Step-by-step explanation:

\frac{4x}{15}=\frac{3}{25}

Your first step is to cross multiply:

15(3)=25(4x)

Simplify both sides:

45=100x  You got this! You go!

Divide both sides by 100:

\frac{45}{100}=x

You wrote 45/100 as .45 which is correct!

Nice.

Write the standard form of the line that passes through (-1,-3) and (2,1)
Pie
Answer:

5 =  - 2x - y
To find this you must find the slope first:
\frac{y - y1}{x - x1}
which is, after performing some calculating is -2.

Next you need to set up your eqaution:
y - y1 = m(x - x1)
when you set it up, and substitute the variables for your slope and points you should get this:
y - ( - 3) =  - 2(x - 1)
y + 3 =  - 2x - 2
add 2 to both sides
y + 5 =  - 2x
subtract y from both sides
5 =  - 2x - y

Need help ASAP thank you
Sergeu [11.5K]

Answer:

x = 14

Step-by-step explanation:

First put it into slope intercept form

20 = 2x - 8

Move the variable to the left hand side and change its symbol

-2x + 20 = -8

Move the constant to the right hand side and change its symbol

-2x = -8 - 20

Calculate the difference

-2x = -28

Divide both sides of the equation by -2

x = 14

Solution

X = 14

Which inequality is graphed on the number line shown?
bearhunter [10]
The graph is to the left of -3, so it's < or ≤.
The circle is filled in so -3 also satisfies the inequality, so it's ≤.
The answer is B. x≤-3.
