I’ve been trying to answer this question and it takes me forever. Can you guys help ,e with this one?

Answer:

x=−0.714286

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

−2.5(−2−3x)+2.5(−4x−1)=−2x−4x

(−2.5)(−2)+(−2.5)(−3x)+(2.5)(−4x)+(2.5)(−1)=−2x+−4x(Distribute)

(7.5x+−10x)+(5+−2.5)=(−2x+−4x)(Combine Like Terms)

Step 2: Add 6x to both sides.

Step 3: Subtract 2.5 from both sides.

Step 4: Divide both sides by 3.5.

x=−0.714286

=====================================

Work Shown:

(f - g)(x) = f(x) - g(x)

(f - g)(x) = ( f(x) ) - ( g(x) )

(f - g)(x) = ( 3^x + 10 ) - ( 2x-4 )

(f - g)(x) = 3^x + 10 - 2x+4

(f - g)(x) = 3^x - 2x + (10+4)

(f - g)(x) = 3^x - 2x + 14

Answer:

first option

Step-by-step explanation:

the area of a rectangle is

base*height

[tex]Purple=(3)\times(a)\\\\=3a\\\\\\Green=(\frac{1}{2})\times(3)\\\\=\frac{3}{2}\\\\\\Red=1\times a\\\\=a\\\\\\Yellow=\frac{1}{2}\times 1\\\\=\frac{1}{2}[/tex]

so the sum is

[tex]\Sigma A=3a+a+\frac{3}{2}+\frac{1}{2}[/tex]

which is the first option

The expression for the area of the poster is written as the sum of the areas of each colored section is 3a + a + 3 1/2 + 1/2

Area of a rectangle = length × width

Purple color:

Area = length × width

= 3 × a

= 3a

Red color:

Area = length × width

= 1 × a

= a

Green color:

Area = length × width

= 3 × 1/2

= 3 1/2

Yellow color:

Area = length × width

= 1 × 1/2

= 1/2

Sum of the areas = purple + red + green + yellow

= 3a + a + 3 1/2 + 1/2

Therefore, expression for the area of the poster is written as the sum of the areas of each colored section is 3a + a + 3 1/2 + 1/2

The equation represents the situation in which x denotes the cost per binder and y denotes the total cost of Jesse’s purchase is 16+3x=y.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

Jesse wants to purchase three binders and a backpack. If the backpack costs $16

From the data given in the question:

The linear equation can be framed as follows:

y = 16 + 3x

Or

16 + 3x = y

Thus, the equation represents the situation in which x denotes the cost per binder and y denotes the total cost of Jesse’s purchase is 16+3x=y.

The options are:

16+y=3x

16+3x=y

y+3x=16

3+16x=y

Answer:

y=2/3x-3

Step-by-step explanation:

first, you have to isolate the y, so subtract 2x from both sides. -3y=-2x+9

Next, we must divide all sides by -3, so y=-2/-3x-3

Finally, simplify the equation to y=2/3x-3

Answer:

y=mx+b

y=2/3x + -3

2/3 is the slope  points are (0,-3)

Step-by-step explanation:

2x-3y =9

subtract 2x from each side leaving it -3y = -2x +9

now divide both sides by -3                 -3y/-3=-2x/-3 +9/-3

                                                                      y= 2/3+ -3

Answer: The independent variable is the brand and the dependant variable is the amount of water you use.

Step-by-step explanation:

The Independent variable is the condition that you change in an experiment.

The dependant variable is the condition that you measure in an experiment.

The independent variable in the student's experiment is the type of paper towel used.

In an experiment, there are three types of variables:

In this question the type of towel used would determine the amount of water that can be absorbed. This makes the type of towel used the independent variable. The dependent variable is the amount of water absorbed.

Answer:

12 + 1.79(x) ≤ 50

Number of drill bits = 21

Step-by-step explanation:

Given:

Total amount = $50

Amount of book = $12

Price of each bit = $1.79

Find:

Number of drill bits

Computation:

Assume, Number of drill bits = x

So,

12 + 1.79(x) ≤ 50

1.79(x) ≤ 38

x ≤ 21.220

Number of drill bits = 21

7n^2 + 5 = 453

Subtract 5 from both sides:

7n^2 = 448

Divide both sides by 7:

N^2 = 64

Take the square root of both sides:

N = 8

The rule of translation of the triangle EFG is (c) T-2,4(x,y)

We  have:

Taking E and E', we have:

E = (-3, 4)

E' = (-1, 0)

Subtract E from E'.

So, we have:

(x, y) = (-1 + 3, 0 - 4)

Evaluate

(x, y) = (2, -4)

This can be rewritten as:

T-2,4(x,y)

Hence, the rule of translation is (c) T-2,4(x,y)

Answer:

A) (1,0), (3,1), and 4,-1)

Step-by-step explanation:

subtract 2 from all of the y-values

(1,0), (3,1), and (4,-1)

So it's A.

Answer:

The answer is A.

Step-by-step explanation:

It would be best to graph this yourself and move each plot down 2 units. Your answer would be the location of the plots after moving them.

at first we should find the equation of this line so we should find a in the equation of y = a x + b and we do not care about b as it is parallel so a = ( (4 -(-2)) ÷ 1 -(-2)) = 2 so y = 2 x + b and we put x = 3 and y = 7 the result is 7 = 2×3 + b and b = 7 - 6 = 1 the equation is y = 2x + 1

======================================================

Explanation:

The set of whole numbers is {0, 1, 2, 3, ...}

So we include 0 and any positive number that doesn't have decimal or fractional components to it. Negative values are not included.

Whatever you pick for x, the y value must add to it to get 3. Both x and y must be numbers from the set of whole numbers.

There are four cases shown in the bullet points above, so we have four different solutions. We can't move onto x = 4 because the y solution would be y = -1, but -1 is not in the set of whole numbers.
