Answer:

y= 3x + 1

Step-by-step explanation:solve for y

subtract 3x from the left  which leaves -y= -3x -1

then you have to take flip the signs or divide by -1  so it comes out to y=3x + 1

Answer:

y = 3x + 1

Step-by-step explanation:

Slope Intercept form is written out as the following:

y = mx + b

In order to convert "3x - y = -1", we first subtract 3x from both sides, giving us:

-y = -3x - 1

Since we have "-y", we multiply -1 on both sides.

-1(-y) = -1(-3x - 1)

Multiplying two negatives makes a positive, hence when we multiply -1 on both sides, it becomes this:

y = 3x + 1

So converting to the Slope Intercept form ends up being "y = 3x + 1"

x=9/34 that's the answer

Step-by-step explanation:

Which graph has a slope of ? A coordinate plane with a straight line. The line starts at (negative 5, negative 4) and passes through points at (0, 1) and (4, 5). A coordinate plane with straight line. The line starts at (negative 5, negative 2) and passes through points at (negative 1, 0) and (4, 5). A coordinate plane with straight line. The line starts at (negative 5, negative 1) and passes through points at (negative 2, 0) and (3, 2). A coordinate plane with straight line.

Answer:

12.04

Step-by-step explanation:

use Pythagorean theorem to find BC then to find ac.

The length of AC from the given trapezium is 12.042 cm.

In the given trapezium, AD=10 cm, AB=9 cm, DC=3 cm.

Draw perpendicular from D to AB, intersecting at X.

So, AX=6 cm

By using Pythagoras theorem, we get

AD²=AX²+DX²

10²=6²+DX²

100=36+DX²

DX²=100-36

DX²=64

DX=8 cm

Here, DX=BC=8 cm

Now, consider triangle ABC and apply Pythagoras theorem, we get

AC²=AB²+BC²

AC²=9²+8²

AC²=81+64

AC²=145

AC=√145=12.042 cm

Therefore, the length of AC from the given trapezium is 12.042 cm.

Answer:

$24,582

Step-by-step explanation:

E = 2.75q + $24,582

The expense equation above has the general relation :

Expense = [(variable cost * number of units) + fixed cost]

The fixed cost incurred is not dependent on the number of units purchased or produced and as such is usually regarded as a constant in the formula.

Thus, the fixed cost in the expense equation is thus : $24,582

Answer:

x=−7/5and y=−6/5

Step-by-step explanation:

Step: Substitute−2x−4foryiny=3x+3:

y=3x+3

−2x−4=3x+3

−2x−4+−3x=3x+3+−3x(Add -3x to both sides)

−5x−4=3

−5x−4+4=3+4(Add 4 to both sides)

−5x=7

Answer:

The perimeter of rectangle is 22x+4 feet.

Step-by-step explanation:

Width of rectangle = 7x-7 feet

Length of rectangle = 4x+9 feet

We need to find perimeter of rectangle.

The formula used is:

[tex]Perimeter\: of\: rectangle=2(Length+ Width)[/tex]

Now, putting values and finding perimeter

[tex]Perimeter\: of\: rectangle=2(Length+ Width)\\Perimeter\: of\: rectangle=2(4x+9+ 7x-7)\\Perimeter\: of\: rectangle=2(4x+7x-7+9)\\Perimeter\: of\: rectangle=2(11x+2)\\Perimeter\: of\: rectangle=22x+4\:feet[/tex]

So, the perimeter of rectangle is 22x+4 feet.

Answer: 8%

Step-by-step explanation:

Original Perimeter of the rectangle is:

= 2 * ( Length * Width)

= 2 * (20 + 30)

= 100 cm

The length increased by 10%. It therefore increased to:

= 30 * ( 1 + 10%)

= 30 * 1.1

= 33 cm

The width increased by 5%. It increased to:

= 20 * ( 1 + 5%)

= 21 cm

New Perimeter is therefore:

= 2 * ( 33 + 21)

= 108 cm

Percentage increase in perimeter is:

= (New perimeter - old) / old perimeter

= (108 - 100) / 100

= 8%

Hey there!

The correct answer is 2x²3y³

Hope it helps and have an amazing day!

The final expression of 2 x X x X x 3 x y x y x y is 2x²y³.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

The expression: 2 x X x X x 3 x y x y x y

There are two X and three y.

Now,

X x X = X²

y x y x y = y³

Now,

2 x X x X x 3 x y x y x y

= 2x²y³

Thus,

The expression is 2x²y³.

Answer:

The value of g(x) ar x = 4 is 84.

i.e. g(4) = 84

Step-by-step explanation:

Given the table

x             0             1             2             3             4

g(x)        0             3             6             15          BLANK

The average rate of change of g(x) over the interval 1 ≤ x ≤ 4 is 27.

at x₁ = 1, g(x₁) = 3

at x₂ = 4,  g(x₂) = g(4) = ?

The average rate of change = 27

Using the formula involving the average rate of change  

Average rate = [g(x₂) - g(x₁)] / [ x₂ - x₁]

substituting x₁ = 1, g(x₁) = 3, x₂ = 4 and Average rate = 27  

                  27  = [g(4)  - 3] / [4 - 1]

                   27 = [g(4)  - 3] / [3]

                27×3 = g(4)  - 3

                  81   = g(4)  - 3

              81+3   = g(4)

                  84 = g(4)

Thus,

The value of g(x) ar x = 4 is 84.

i.e. g(4) = 84
