dusya [7]4 years ago
3 0

Answer:

same slope and same y intercept

Step-by-step explanation:

y + 11 = -7/9 (x - 18)

y + 11 = -7/9x + 14

y = -7/9x + 3

Find the values of a, b and c.
valina [46]

Look at the picture.

Corresponding Angles are equal.

Alternate Angles are equal.

Consecutive Angles add up to 180°.

----------------------------------------------------------------------

3a and 45 are Consecutive Angles. Therefore

3a + 45 = 180    |subtract 45 from both sides

3a = 135      |divide both sides by 3

<h3>a = 45.</h3>

----------------------------------------------------------------------

(2c - 1) and 45 are Corresponding Angles. Therefore

2c - 1 = 45     |add 1 to both sides

2c = 46     |divide both sides by 2

<h3>c = 23.</h3>

----------------------------------------------------------------------

3a and (12b + 3) are Alternate Angles. Therefore

3(45) = 12b + 3

135 = 12b + 3     |subtract 3 from both sides

132 = 12b      |divide both sides by 12

<h3>b = 11.</h3>

A number is equal to twice a smaller number plus 3. The same number is equal to twice the sum of the smaller number and 1. How m
Pie

Answer:

No solutions exist because the situation describes two lines that have the same slope and different y-intercepts.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to call the numbers x and y.

A number is equal to twice a smaller number plus 3.

Greater number is x, and smaller is y. So

x = 2y + 3

The same number is equal to twice the sum of the smaller number and 1.

This means that x = 2y + 1

Equaling the values for x:

2y + 3 = 2y + 1

0y = -2

y = -\frac{2}{0}

Since division by 0 does not exist, it means that there is no solution for the system.

What is the point-slope form if it's through (1,4) and the slope is 3
Ratling [72]

For this case we have that by definition, the equation of the line of the point-slope form is given by:

y-y_ {0} = m (x-x_ {0})

Where:

m: It's the slope

(x_ {0}, y_ {0}):It is a point through which the line passes

According to the given statement we have:

(x_ {0}, y_ {0}) :( 1,4)\\m = 3

Substituting we have:

y-4 = 3 (x-1)

Finally, the equation is:

y-4 = 3 (x-1)

Answer:

y-4 = 3 (x-1)

The function y = -x - 1 and y = ½x + k intersect at the point (-2,1). Find the value of k.
horrorfan [7]

Answer:

  k = 2

Step-by-step explanation:

Fill in the given point values and solve for k.

  y = (1/2)x + k

  1 = (1/2)(-2) +k . . . . . . for x = -2, y = 1

  1 = -1 +k . . . . simplify; next, add 1

  2 = k
