Answers

2x + 4y = 8
x = 3y - 6

2x + 4y = 8
2 * ( 3y - 6 ) + 4y = 8
6y + 12 + 4y = 8
8y = 8 - 12
8y = - 4

Step-by-step explanation:

Step 1: Define

f(x) = 2x² - 4x - 3

g(x) = -2x² - 16

Step 2: Find f(x) + g(x)

Substitute:                              f(x) + g(x) = 2x² - 4x - 3 - 2x² - 16Combine like terms (x²):        f(x) + g(x) = -4x - 3 - 16Combine like terms (Z):         f(x) + g(x) = -4x - 19

Jeremy was 45 inches tall when he started kindergarten. He grew an average of 2.5
inches every year. Jeremy is now 62.5 inches tall.
Which equation can be used to find how many years ago Jeremy started kindergarten,
and how many years ago was it?

Answers

Answer:

subtraction

Step-by-step explanation:

its subtraction because if you do 62.5-2.5 it = 60 and then 60-2.5=57.5 57.5-2.5=55 55-2.5=52.5 52.5-2.5=50 50-2.5= 47.5 47.5-2.5 = 45 s so it was 7 or 8 years ago idk count them see how many times i did it

the ratio of 82 and 73​

Answers

Answer: 82:73

Step-by-step explanation:

To find an equal ratio, you can either multiply or divide each term in the ratio by the same number (but not zero). For example, if we divide both terms in the ratio 3:6 by the number three, then we get the equal ratio, 1:2. Do you see that these ratios both represent the same comparison?

whatis the value of y?​

Answers

Answer is A, y = 65

The top angle is 50 because 180 - 130 = 50
Since the top angle is 50, the two bottom angles have to add up to 130. Since the bottom angles are the same, you can do 130 / 2 to find the angles which equals 65.

Answer:

Finding the y value is easy if you know the slope of the line and the x coordinate. Review the equation for the slope of a line. The equation for finding the slope is: m = [y1 - y2] / [x1 - x2]. If you know x, you can solve for y to find the y value for the slope of the line.

Step-by-step explanation:

in the graph shown below, if lines 1^1 are parallel, then the slope of the line 1^2 is?

Answers

Answer:

Two lines are parallel if the have the same slope. Example 1: Find the slope of the line parallel to the line 4x – 5y = 12. To find the slope of this line we need to get the line into slope-intercept form (y = mx + b), which means we need to solve for y: The slope of the line 4x – 5y = 12 is m = 4/5.

Step-by-step explanation:

good morning

If the lines l1 and l2 are parallel, then the slope of line l2 is the same as the slope of line l1.

The slope-intercept definition of a linear function is given as follows:

y = mx + b.

For which the parameters are given as follows:

m is the slope, representing the rate of change of the function.

b is the intercept, representing the value of y when x = 0.

When two lines are parallel, they have the same slope.

Hence, If the lines l1 and l2 are parallel, then the slope of line l2 is the same as the slope of line l1.

What’s the value of k ?

Answers

Hello!

[tex]\large\boxed{k = 10^{o}}[/tex]

When given two interior angles and an exterior angle, the sum of the two interior angles is equal to the sum of the exterior angle. Therefore:

m∠YZX + m∠ZXY ≅ m∠MYZ

(4k + 5)° + (6k + 10)° = 115°

Combine like terms:

10k + 15 = 115°

Subtract 15 from both sides:

10k = 100°

Divide both sides by 10:

k = 10°

Answer:

k=10

Step-by-step explanation:

First you would find the missing angle at the top this would be 65 degrees, this means that the 2 other missing angles must total to 115 degrees.

Second you would set the equations equal to 115

4k+5+6k+10=115

Then you would combine the like terms

10k+15=115

next you would subtract the 15 from both sides

10k=100

then you divide by 10

k=10

Step-by-step explanation:

Answer:

First result: X = 248/3 or 82.67    Second result: X = 260/3 or 86.57

Step-by-step explanation:

1st one: 7x + 8(x + 1/4) = 3(6x - 90 - 8)

              7x + 8x + 2 = 18x - 270 - 24

                 15x + 2 - 2 = 18x - 246 - 2

                  15x - 18x = 18x - 18x -248

                -3x = 248  -->   -3x/3 = 248/3

                    X = 248/3 or X = 82.67

2nd one: 7x + 8(x+1/4) = 3(6x - 90) - 8

                  7x + 8x + 2 = 18x - 270 - 8

                   15x + 2 - 2 = 18x - 262 - 2  

                    15x - 18x = 18x -18x - 260

                   -3x = 260 --> -3x/3 = 260/3

                        X = 260/3 or X = 86.67

O (0,3)

Answers

Answer:

(3,0)

Step-by-step explanation:

y= 2/3x - 2 ... (1)

y= -x+3 ... (2)

First, change the equations into normal equation form

(1): - 2/3x + y= - 2

(2): x+y= 3

(1)×3: - 2x+3y= - 6 ... (3)

(2)×2: 2x+2y= 6 ... (4)

(3)+(4): 5y=0

y= 0

Substitute y=0 into any equation

Let's say, equation (2)

y= -x+3

0= -x+3

-3= -x

x= 3

(x,y)= (3,0)
