Solve for y in the following equations: -4x -8y = -8 when x = -4

A) 5
B) 3
C)-5
D) 8

Answer:

x = 10°

y = 25°

Step-by-step explanation:

3x = 5x - 20  because they are alternate interior angles

subtract 5x from each side of the equation:

-2x = -20

Divide both sides by -2:

x = 10°

The sum of the interior angles of any triangle = 180°

2y + 4Y + (5x - 20) = 180°

combine like terms:

6y + 5x - 20 = 180°

add 20 to each side:

6y + 5x = 200°

substitute for x:

6y + 5(10) = 200°

subtract 50 from each side:

6y = 150°

divide both sides by 6:

y = 25°

Answer:

The percent change is 87.5%. (You're one chonky boi lol)

Step-by-step explanation:

To find the percent change, calculate the difference between the new weight and the old weight and divide that value by the old weight and multiply by 100% to find the percent change. In this case, the equation would be [tex]\frac{225-120}{120}[/tex] * 100% = [tex]\frac{105}{120}[/tex] * 100% = 0.875 * 100% = 87.5%, so the correct answer is a percent change of 87.5%.

Answer:

[tex]53\frac{1}{3}[/tex] %

Step-by-step explanation:

[tex]\frac{120}{225} =\frac{y}{100}[/tex]

225 × y = 120 × 100

225y = 12000

225y ÷ 225 = 12000 ÷ 225

[tex]y=53\frac{1}{3}[/tex]

Answer:

-x + 1

Step-by-step explanation:

First, rewrite 2x +3 - 3x + (-2) as 2x +3 - 3x - 2.  Note that +(-2) = -2.

Next, combine like terms.  We get -x + 1.  

Double check to determine whether this is one of the given possible answers.

Answer:

4xy + 4x² + 4xz

Step-by-step explanation:

4x(y+x+z)

4xy + 4x² + 4xz

Answer:

4xy+4x^2+4xz

Step-by-step explanation:

You would just factor the first 4x to the rest of the terms and if they are different letters just tack them on at the end, in the case of 4x times x it would square to 4x^2

2970

Step-by-step explanation:

I hope it helped :) if it didnt just message me since in confused whats the dot between the 6.3 and 10²

Answer:

2.97*10^3

Step-by-step explanation:

You have to solve it first so you have 2970 as your answer but you want it in scientific notation. To do this put the decimal after the first number this gives you 2.970. Whenever you need to make the number bigger you use a positive power and whenever you want to make a number smaller you use a negative power. The amount of powers the 10 gets is the amount of times you move it over. You have 2.970 and to get to the original number you need to move it 3 places to the right. Going to the right with your decimal makes it bigger which what you want, so you have 2.970*10^3 as your answer.

Answer:

1) 22/20 = 1.1

2) 18/15 = 1.2

3) No, because they both are different values and their slopes are different.

Answer:

3, 9, 15, 21, 27, 33, 39, 45...

Step-by-step explanation:

Los números que son múltiplos de 3 mas no de 2 son todos aquellos número que, formando parte del grupo de números divisibles por 3, sean impares. Es decir que todo número divisible por 3 que no termine en un número par no será divisible por 2. Ello es así porque todos los números pares son divisibles por 2.

Answer:

slope = - 1

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (4, - 5) and (x₂, y₂ ) = (- 2, 1)

m = [tex]\frac{1+5}{-2-4}[/tex] = [tex]\frac{6}{-6}[/tex] = - 1

Answer:

-1

Step-by-step explanation:

To find the slope, plug the values of x and y into the slope formula.

y2 - y1 / x2 - x1

1 - (-5) / - 2 - 4

6 / -6

= -1

Pattern A starts at 0 and uses the rule Add 2

Answer:

(-0.6)^3

Step-by-step explanation:

Here, we want to write the given expression in exponential terms

From what we have, there is a repetitive term

For example, if we had;

(x)(x)(x)

Exponentially, we will have this written as x^3

Using the above technique in what we have at hand

(-0.6)(-0.6)(-0.6) = (-0.6)^3

Answer:

-3/4x + 1/4

Step-by-step explanation:

Given equation of line: y = mx+c,

where m = slope and c = y-intercept

given m = -3/4,x = -5, y=4,

[tex]4 = ( - \frac{3}{4} )( - 5) + c \\ c + 3.75 = 4 \\ c = 0.25 \: or \frac{1}{4} [/tex]

therefore equation of line :

[tex]y = - \frac{3}{4} x + \frac{1}{4} [/tex]

therefore answer is the first one.
