Answer:

∠ AFE = 80°

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 )

∠ AFE = 80°

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

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.

Area of parallelogram

= Vertical height * Base

= (8m)(6m) = 48m².

The area is 48 square meters.

Answer:

48 square meters

Step-by-step explanation:

First we know there are two triangles the same size and because, the formula is A = 1/2b*h. Therefore, we only have to do the math for one triangle to make up for both triangles.

2*8=16.

Then because, 6 is for both the triangle and the square it would be 4*8=32

32+16=48

48

Therefore, your answer would be 48 square meters.

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
