When a number x is multiplied by 4, the result is 25 .

Effectus [21]

Hello,

To solve this question, a good method to use is creating an equation.

The number x being multiplied by 4 can be represented as 4x.
If this results in 25, we can create the equation:

4x = 25

To solve for x, you want to remove the coefficient of 4 from x, so we can divide by 4 on both sides (doing this we will only get x on the left side of the equation, which is what we are trying to solve for).

So, dividing by 4 on both sides, we have
(4x / 4) = (25 / 4)
x = 25/4

x = 25/4, which cannot be further simplified as a fraction. However, this can be represented by 6.25 in decimal form.

x = 25/4, or 6.25

Hope this helps!

What is the equation of the line that passes through the point (6,14) and is parallel to the line with the following equation? y

Gekata [30.6K]

Answer:

$y=\displaystyle-\frac{4}{3}x+22$

Step-by-step explanation:

Hi there!

What we need to know:

Linear equations are typically organized in slope-intercept form: $y=mx+b$ where m is the slope and b is the y-intercept
Parallel lines always have the same slope (m)

Determine the slope (m):

$y=\displaystyle-\frac{4}{3}x -1$

The slope of the given line is $\displaystyle-\frac{4}{3}$ , since it is in the place of m in y=mx+b. Because parallel lines always have the same slope, the slope of a parallel line would also be $\displaystyle-\frac{4}{3}$ . Plug this into y=mx+b:

$y=\displaystyle-\frac{4}{3}x+b$

Determine the y-intercept (b):

$y=\displaystyle-\frac{4}{3}x+b$

To find the y-intercept, plug in the given point (6,14) and solve for b:

$14=\displaystyle-\frac{4}{3}(6)+b\\\\14=-8+b\\b=22$

Therefore, the y-intercept of the line is 22. Plug this back into $y=\displaystyle-\frac{4}{3}x+b$ :

$y=\displaystyle-\frac{4}{3}x+22$

I hope this helps!

I need the perimeter

krek1111 [17]

Answer:

42

Step-by-step explanation:

to find the perimiter youre gonna want to add up all the sides you already have,

so we have 4, 4, 11, and 6.

the reason we dont count the other 4 inside of the figure is because that is inside of it, so we would consider that perimiter

as we see there are other sides not labeled. we have to use that area four to help us.

for the top left side, we do 6 - 4 = 2

for the bottom right side, we do 11 - 4 = 7

then, as we see at the top right we have a four labeled, these look the same width so add a four.

and at the top left, we see another four so add that.

then, add up everything giving you 42.

i hope this helped! <3
