Consider the following equation. 4x + 2 = 8x - 5 Which equation and explanation could represent a step in finding the value of x? (4x) + 2 = * (8x) - 5 Use the multiplication property of equality to simplify the variable term on the left side of the equation. 4x + 2-5= 8x - 5 + 5 Use the addition property of equality to move the constants to one side of the equation. 11 / + 2 (4x + 2) = | (8x - 5) Use the multiplication property of equality to simplify the variable terms on both sides of the equation. O 4x + 2 - 4x = 8x - 5 - 4x Use the addition property of equality to move the variables to one side of the equation.​

Answer:

Step-by-step explanation:

For the first one here is the answer:

Given.

Transitive property of equality- this is becasue the rule is if A=b and B=c then A=c. IN this situation its saying that a is parrelel to b and b is parralel to c therfore a is parrelel to c.

line A and d cross over at 90 degree angles making them perpendicular. -There should be a rule for this and if there is then write that rule down

Second answer:

Given.

Definition of a  supplementary angle.

-Srry for the definiton of supplementary angles thing but thats the best answer for those.

Answer:

Step-by-step explanation:

Cos(90-2x) . tan(180+x) + sin^2(360-x)​

= sin(2x) * tan(x) + sin²(x)

= 2sin(x) cos(x) sin(x)/cos(x) + sin²(x)

= 2sin²(x) + sin²(x)

= 3sin²(x)

Answer:

The area of a rectangle is the product of its dimensions. Your park has an area of

 (5/8 mi)×(2/3 mi) = 10/24 mi² = 5/12 mi²

Step-by-step explanation:

Veremos que el otro lado  del triangulo debe medir 20 metros.

Sabemos que para un triangulo rectangulo de catetos P y K, el area es:

A = P*K/2

En este caso, sabemos que el menor de los catetos mide 5 metros, entonces tenemos:

P = 5m

Y tambien sabemos que el area es de 50m^2, reemplazando eso en la ecuación de arriba obtenemos:

50m^2 = 5m*K/2

Ahora podemos resolver esto para K

(50m^2)/5m = K/2

10m = K/2

2*10m = K = 20m

El otro lado debe medir 20 metros.

C)  1340 days

Step-by-step explanation:

The composite function you have given is incorrect.

The composite function for this question is:

t(d) = 60d + 20

(as I have proven in a previous question)

Substitute d = 22 into the function:

t(22) = 60(22) + 20

        = 1320 + 20

        = 1340 days

Answer:

$40.80

Step-by-step explanation:

First, convert the 20% to an actual number that can be used in a calculation. For percent, this is always done by simply dividing the percent, in this case, 20%, by 100%. So, the conversational term "20%" becomes 20% / 100% = 0.20 in terms of a real mathematical number.

Second, you need to find out what 20% of your $34.00 meal cost is. This is always done by multiplying 0.20 by $34.00, or 0.20 x $34.00=$6.80. So, the amount of tip you are going to leave is $6.80.

This makes the total cost of your meal (to write on your charge slip or other payment)

$34.00 + $6.80 = $40.80.

Answer:

$40.80

Step-by-step explanation:

If you pay for the original cost of the dinner AND leave a 20% tip then the total amount paid will be 120% of the original cost (100% + 20% = 120%).

Convert 120% into a decimal:  120% = 120/100 = 1.2

So 120% of $34.00 = 1.2 × 34 = $40.80

Answer:

yˆ=2.608x2−115.265x+1568.065

Step-by-step explanation:

I took the test.

The quadratic regression equation best fits the data set is 2.608x²  -155.264x + 1568.064 option second is correct.

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

Let's suppose the quadratic regression equation best fits the data set:

y = Ax² + Bx + C

From the data set, we can calculate the value of the A, B and C:

A = 2.608

B = -155.264

C = 1568.064

y = 2.608x²  -155.264x + 1568.064

Thus, the quadratic regression equation best fits the data set is 2.608x²  -155.264x + 1568.064 option second is correct.

Answer:

y=-5x+35

Step-by-step explanation:

Use the formula y = mx + b

m = slope, so plug in -5 as the slope

To find x-intercept we set y=0

We want the x-intercept to be 7 so we can plug that into the equation too

0=-5(7)+b

Lastly solve for b and you get your answer

Which is y=-5x-35 :) hope this helps
