Given 28-6x=2x-84 prove x=14.

Answers

Answer:

-56

Step-by-step explanation:

substitute x with 14 in the equation and both answers will be -56

28-6x = 2x -84

Add 6x to both sides:

28 = 8x -84

Add 84 to both sides

112 = 8x

Divide both sides by 8

X = 112/8

X = 14

HELP brainlest included 1 hours timed

Answers

Answer:

x=7

Step-by-step explanation:

first, add 12 to both sides so it would look like: 6x-12+12=30+12

so, ya get 6x=42

then you divide 6 from both sides, and that is: 6x/6=42/6

so x=7

1) add 12 to both sides

6x= 30+12

2) add 30 and 12 to get 42

6x= 42

3) divide both sides by 6

x= 42/6

x=7

What was the percentage increase to one decimal place?

NO SILLY ANSWERS OR REPORT!

Answers

Answer:

13%

Step-by-step explanation:

The percentage decrease is calculated by the formula below;

( new value - old value)old value * 100%

old value is 130

new value is 115

So the percentage increase will be;

(130-115)/115 * 100%

= 15/115 * 100% = 13.043%

To one decimal place, this is 13%

it’s asking for x intercepts

h(x)=2x+5 k(x)=x+3 find (h(k(x)))

Answers

Answer:

h(k(x)) = 2x + 11

Step-by-step explanation:

Step 1: Define

h(x) = 2x + 5

k(x) = x + 3

h(k(x))

Step 2: Substitute and Evaluate

k(x) = x + 3 = x

h(k(x)) = 2(x + 3) + 5

h(k(x)) = 2x + 6 + 5

h(k(x)) = 2x + 11

Hailey is putting up a fence in the shape of an isosceles triangle in her backyard. The fence has side lengths as shown, where x represents the number of feet in each fence section. The perimeter of the fence can be covered using 8 total fence sections represented by the expression 8x. If fencing costs $6.50 a foot, what would be the total cost of the fence?

Answers

Answer: The total cost would be $780.00

The expression for the total cost of fencing is $52x , where x is a variable representing the number of feet in one section.

What is an expression in one variable?

An expression in one variable is a statement formed by the using constants and an unknown variables and mathematical operators but sign is equal to is not used. Expression in one variable is linear if the power of the unknown variable is equal to one .

Given that number of feet in one fence section be x

No of feet in 8 such fence section = 8x

Given , Perimeter = 8 fence sections = 8x feet

Cost of fencing of one foot = $6.50

Cost of fencing 8x feet = 8x * 6.50

Therefore , the total cost of the fencing can be given by = 8x*6.50

                                                                                                  = $ 52 x

Thus, the expression for the total cost of fencing is $52x

Answer:

y = 3 + 1/1

Step-by-step explanation:

First, the line passes the y-intercept at 3, so we have y = 3. But we also need the slope. Because the slope is 1/1 or 2/2, the equation would be this:

y = 3 + 1/1

Plot the image of point Q under the translation (x, y) + (x - 3, y + 4).​

Answers

Answer:

( 2, -1 )

Step-by-step explanation:

The image of the assumed point Q(2, 3)) under the translation is Q'(-1, 7).

What is Translation?

Translation is a type of transformation of geometrical figures. After translation, the original figure is shifted from a place to another place without affecting it's size.

Translation of a point (x, y) indicates that the point is moved x units along the X axis and y units along the Y axis,

Here we have to translate the point Q(2, 3).

Point (x, y) is translated as (x - 3, y + 4).

That is the point (x, y) moves 3 units to the left along the X axis and 4 units upwards along the Y axis.

Q(2, 3) after the translation becomes,

Q'(2 - 3, 3 + 4) = Q'(-1, 7)

Hence the point Q(2, 3) under the translation (x - 3, y + 4) is the point Q'(-1, 7).
