Someone please help me I have to turn this in tomorrow

Answers

first combine like terms, let’s look at the equation.

5n + 3n - n + 5 = 26

if we combine the like terms we are left with -
7n + 5 = 26

next you want to subtract 5 from both sides of the equation -
7n + 5 - 5 = 26 - 5

then you want to simply -
7n = 21
7n/7 = 21/7

cancel terms that are both the numerator and denominator & divide the numbers -
n = 3

Answers

Answer:

12 < x < 13

Step-by-step explanation:

Pythagorean Theorem: a^2 + b^2 = c^2

a is 6, b is 11, c is x.

We have to first replace the items in the Theorem, do the exponents, then add.

1) 6^2 + 11^2 = x^2

2) 36 + 121 = x^2

3) 157 = x^2

To finally solve it we must square root everything

4) sqrt(157) = sqrt(x^2)

5) x = 12.52

So x has to be between 12 and 13

Translate the sentence into an equation.
Six less than the product of 4 and a number equals 2 .
Use the variable c for the unknown number.

Answers

Answer:

(4xc)-6=2 then c=2

Step-by-step explanation:

because we knew that we had to do 6+2=8 so then 8 divided by 4 = 2 so the answer would be 2!

Answer:

(4c) - 6 = 2

4c - 6 = 2

c = 2

Both equations will work.

Step-by-step explanation:

"The product of 4 and a number" is the same as 4 times that number.

Since the missing number is to be said as c, the correct term for this is 4c

6 less than (4c) is the same as (4c) - 6

We have the left-hand-side of the equation as (4c) - 6

The right-hand side is 2

(4c) - 6 = 2or4c - 6 = 2

Now, we have to solve for c.

4c - 6 = 24c = 8c = 2

SOLVE & SHOW YOUR WORK !!!!

Answers

Answer:

Step-by-step explanation:

You have to assume that the triangles are congruent or at least similar. If they are not, the question isn't possible.

If that is so, then <M and <X are equal.

You can find < M by stating that 20 degrees.

That's because <L + <M + <N = 180 degrees. All triangles have 180 degrees.

<L = 70                  Given

<N= 90                  So marked.

70 + <M + 90 = 180

<M = 20 degrees.

<X = <M

<X = 20

Graph 3x-4y=-12 using intercepts.


Will mark brainliest if right

Answers

Answer:

See the attached file

There is also this app "desmos" it helps in this just put the equation in there

Answer:

Read below

Step-by-step explanation:

Slope-intercept form: y = mx + b

where:

m is the slopeb is the y-intercept (when x = 0)

1. Rewrite 3x - 4y = -12 into slope-intercept form:

3x - 4y = -12 [subtract 3x from both sides]

3x - 3x - 4y = -12 - 3x

-4y = -3x - 12 [divide both sides by -4]

-4y ÷ -4 = -3x - 12 ÷ -4

[tex]\implies y =\dfrac{3}{4}x + 3[/tex]

Note: with the slope-intercept form, we can quickly see that the y-intercept is (0, 3)

2. Randomly choose x-values that can help you graph the equation:

When x = -8:

[tex]y =\dfrac{3}{4}x + 3\\\\y =\dfrac{3}{4}(-8) + 3\\\\y =-\dfrac{24}{4} + 3\\\\y =-6 + 3\\\\\implies y=-3[/tex]

coordinate: (-8, -3)

When x = -4:

[tex]y =\dfrac{3}{4}x + 3\\\\y =\dfrac{3}{4}(-4) + 3\\\\y =-\dfrac{12}{4} + 3\\\\y =-3 + 3\\\\\implies y=0[/tex]

coordinate: (-4, 0)

When x = 8:

[tex]y =\dfrac{3}{4}x + 3\\\\y =\dfrac{3}{4}(8) + 3\\\\y =\dfrac{24}{4} + 3\\\\y =6 + 3\\\\\implies y=9[/tex]

coordinate: (8, 9)

Graph these coordinates and draw a linear (straight) line through them.

Option C is the correct answer.

What are coordinates in a graph?

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

The graph has the following coordinates.

(0, 0), (3, 3), (4, 0), (5, -4), and (9, 0)

Now,

We see that,

From (0, 0) to (3, 3),

y increases as x increases.

And,

From (3, 3) to (4, 0).

y decreases as x increases.

And,

From (4, 0) to (5, -4).

y decreases as x increases.

And,

From (5, -4) to (9, 0).

y increases as x increases.

Thus,

The relationship between x and y in the graph is as x increases, y increases, then y decreases, then y increases again.
