I WILL MARK BRAINLIEST!!!!!! A direct variation function includes the ordered pair (4, 5). If y varies directly with x, and y is

Answer: x=5

Step-by-step explanation:

\frac{2}{14} =\frac{x}{35}

\frac{x}{35}=\frac{2}{14}

simplify

\frac{x}{35}=\frac{1}{7}

multiply 35 on both sides

\frac{35x}{35}=\frac{1\cdot \:35}{7}

\frac{1}{7}  \cdot 35=5

x=5

A rectangular table is four times as long as it is wide. If the area is 36 ft2, find the length and the width of the table.
FrozenT [24]

Answer:

The width is 3 ft

The length is  12 ft

Step-by-step explanation:

Let w = width

l = 4w

A = l*w

Replace length with 4w

A = 4w*w

36 = 4 w^2

Divide each side by 4

36/4 = 4w^2/4

9 = w^2

Take the square root of each side

sqrt(9) = sqrt(w)

3 =w

The width is 3 ft

The length is 4*3 = 12 ft

How do you solve this using system of equations <br> y = 3x -1 <br> y = -x +3
Allisa [31]

Answer:

1

Step-by-step explanation:

The first equation's y value can be replaced with -x + 3, then solve it:

3x - 1 = -x + 3

3x + x = 3 + 1

4x = 4

x = 4 divided by 4

x = 1

Unit 6, Lesson 15
I am Lyosha [343]

Based on the calculations, we can predict that 2, 3, 4, 5, etc., will make the inequality true.

<h3>How to solve an inequality?</h3>

In Mathematics, an inequality can be used to show the relationship between two (2) or more integers and variables in an equation.

Evaluating the given inequality, we have:

-1 ≤ x/2

-2 ≤ x

x ≥ 2.

Therefore, we can predict that 2, 3, 4, 5, etc., will make the inequality true.

Next, we would complete the table to check our prediction:

x        -4     -3     -2      -1     0    1      2    3    4  

x/2     -2    -1.5    -1    -0.5   0   0.5   1    1.5   2

When x = -2:

-1 ≤ -2  (false)

When x = 2:

-1 ≤ 1 (true)

When x = 3:

-1 ≤ 3  (true)

When x = 4:

-1 ≤ 4  (true)

8 less than the product of 5 and-4
alina1380 [7]
So it says 8 less than, meaning 8 minus the product of 5 and -4, so literally it means subtract 8 from 5X-4

Find the area of the figure will give brain illest if correct! ​
Travka [436]
I’m sure that the area is 80. If you do 10 times 5, that will be 50.Then if you do 6 times 5, for the upper remaining part of the figure it would be 30. So 30 plus 50 is 50. Hope this helps!
