Answer:

x = 35/9 or 3 8/9

Step-by-step explanation:

removing the fractions implies using the distributive property, which is multiplying each term outside the parentheses by each term inside

in this problem, after distributing 3/5 we get:

3/5x - 3 = -2/3

we want to isolate the 'x' so we undo subtraction first by adding 3 to each side to get:

3/5x = 9/3 - 2/3

3/5 x = 7/3

x = 7/3 × 5/3

x = 35/9

3/5x = 7/3

we can get the 'x' by itself if we multiply each side by the reciprocal of 3/5, which is 5/3 to get:

x = 7/3 × 5/3

x = 35/3

The answer is 83°

Step-by-step explanation:

by the sum of iner and outer angle=180°

180-126= 54°

B. y=3x+1

Step-by-step explanation:

#Hopeee Itttt Helppsssssss!

A proportion relationship is a direct relationship between two variables thus y = 4x will be the proportional relationship between x and y thus option (D) will be correct.

The ratio is the division of the two numbers.

Proportion is the relation of a variable with another. It could be direct or inverse.

A proportional relationship is given as,

A ∝ B

Removing proportionality

A = kB

Here, k is the constant of proportionality.

As per the given in last option,

y = 4x

x = (1/4)y

Removing constant.

x ∝ y

Hence "A proportion relationship is a direct relationship between two variables thus y = 4x will be the proportional relationship between x and y".

Answer:

x=[tex]\sqrt{2}[/tex]/4 and x=-[tex]\sqrt{2}[/tex]/4

Step-by-step explanation:

One method of solving is using the Quadratic Formula: -b ±[tex]\sqrt{b^{2}-4ac }[/tex]/2a, with a=8, b=0, and c=-1.

After plugging these values in you get -0±[tex]\sqrt{0^2-(4*8*-1)}[/tex]/2*8

After simplifying you get ±[tex]\sqrt{32}[/tex]/16

Because 32 is 2^5, you can simplify it to 4[tex]\sqrt{2}[/tex], which makes the equation ±4[tex]\sqrt{2}[/tex]/16, or ±[tex]\sqrt{2}[/tex]/4.

Answer:

x=13

Step-by-step explanation:

Switch sides:

2x−9=17

Add 9 to both sides:

2x−9+9=17+9

Simplify

2x=26

Divide both sides by 2:

2x/2 =26/2

Simplify to get the result.

x=13

Answer:

Answer:

40

Step-by-step explanation:

both angles are corresponding angles which means both are equal

i.e

4x-50 = 2x+30

4x-2x = 50+30

2x = 80

x = 80/2

therefore x = 40

Answer:

1st option

Step-by-step explanation:

let the three consecutive integers be n , n + 1 , n + 2 , then adding gives

n + n + 1 + n + 2 = 51, simplifying

3n + 3 = 51 ( subtract 3 from both sides )

3n = 48 ( divide both sides by 3 )

n = 16

n + 1 = 16 + 1 = 17

n + 2 = 16 + 2 = 18

The 3 consecutive integers are 16, 17, 18

Answer:

-18

Step-by-step explanation:

b(12) = 4 - 2(12-1)

= 4 - 2(11)

= 4 - 22

= -18

A.  In the quadratic regression model, the explanatory variable is time and the response variable is the height.

The explanatory variable (or the independent variable) always belongs on the x-axis (represented as the first column of the table).

Regression analysis is a set of statistical processes for estimating the relationships between a dependent variable and one or more independent variables.

The response variable (or the dependent variable) always belongs on the y-axis (represented as the second column of the table).

According to the explanation above the correct choice is A.
