Answer 1

Answer:

A - 105

Step-by-step explanation:

since the two measurements are supplements, you do x+82+x+112=180. then you get x=-7. then you do 112-7=105

Answer 2

Answer:

105°

Step-by-step explanation:

A line equals 180, so take the two expressions and set them equal to 180:

x+82+x+112=180

simplify:

2x+194=180

2x=-14

x=-7

now plug the x value into the bolded expression

x+112

-7+112 = 105°

Answers

Answer:

a) 23x

b) 8n

c) -6y

d) -17w

Explanation:

When combining like terms, if there is an addition operator, add both coefficients and carry the variable over. If there is a subtraction operator, subtract both coefficients and carry the variable over. Remember, you can only combine like terms if the variable, and exponent are the same. The addition and subtraction symbols are examples of an operator used in arithmetic. For example, 9x + 14x could be like adding 9 objects and 14 objects together, you have 23 objects total because 9 + 14 = 23. When you add negative numbers, it is like subtracting. When you subtract negative numbers, it is like adding. Negative just means opposite.

a) 9x + 14x = (9+14)x = (23)x = 23x

b) -2n - 10n = (-2+10)n = (8)n = 8n

c) 8y - 14y = (8-14)y = (-6)y = -6y

d) -6w - 11w = (-6-11)w = (-17)w = -17w

Answer:

a: 23x

b: 8n

c: -6y

d: -17w

Step-by-step explanation:

you just add/subtract the numbers then add the variable at the end

17x - y < 13
I’m slope-intercept form

Answers

Answer:

y > 17x - 13

Step-by-step explanation:

We want to write the inequality in slope-intercept form

The general slope intercept form is;

y = mx + b

where m is the slope and b is the y-intercept

So what we have to do to the inequality is to make y the subject

Thus, we have that;

17x -13 < y

Flipping this, we have

y > 17x-13

Step-by-step explanation:

Because all the sides are the same length, we know this triangle is an equilateral triangle. In an equilateral triangle, all the angle measures are the same as well, and the sum of all the angles in a triangle is 180 degrees. So we have the equation:

(3x)3= 180

Step-by-step explanation:

Since BD is a straight line , then

∠ AFB + ∠ AFE + ∠ EFD = 180°, that is

50° + ∠ AFE + 50° = 180°

100° + ∠ AFE = 180° ( subtract 100° from both sides )

Find the slope of the line that passes through (-7, 1.3) and (-7, 14.2)

Answers

Answer:

The slope of the line that passes through (-7, 1.3) and (-7, 14.2) is undefined.

Step-by-step explanation:

Given the points

(-7, 1.3)(-7, 14.2)

Finding the slope between  (-7, 1.3) and (-7, 14.2):

It is clear that the value of x-coordinate remains the same, no matter what is the value of y is.

In other words, the given line is vertical.

i.e. [x₂ - x₁] = -7 - (-7) = -7+7 = 0

We know that the slope of a vertical line is undefined.

i.e.

Using the slope formula

Slope =  [14.2 - 1.3] / [0]

Hence, the slope of the line that passes through (-7, 1.3) and (-7, 14.2) is undefined.
