HELP QUICK!Determine the approximate value of side a.

Answer:

x=6, y=128

Step-by-step explanation:

set 5x+16 = 7x+4

-2x=-12

x=6

plug x into equation= 46

180-46=134

y+6=134

y=128

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

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.

Answer:

m∠1=131

m∠2=49

Step-by-step explanation:

Remember that a line is 180 degrees. To find the measure of angle 2 you will take 180-131= 49.

The measure of angle 1 matches to 131 degrees since it is an alternate interior angle.

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°

Answer:

[tex] {(a + b + c)}^{2} = {(5 + 4 + 3)}^{2} \\ = {12}^{2} \\ = \boxed{144}[/tex]

Yes you are correct because the relationship in the table is y = x - 1

Answer:

An expression is a number, a variable, or a combination of numbers and variables and operation symbols. An equation is made up of two expressions connected by an equal sign.

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

Answer:

25%

400%

Step-by-step explanation:

37=148x

x=0.25

25%

148=37x

x=4

Answer:

first: 37×100=3700

3700/148=25 percent

second: 148×100=14800

14800/37 =400 percent.

hope I helped u. pls mark me❤️

Answer:

X= 20 degrees

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

9x= 180

X =20

Answer:

B. [tex]k(x)=(-x+3)^{1/2}[/tex]

Step-by-step explanation:

When we're talking about a restricted domain, we're looking for a function that's undefined for certain values of x. A classic example is the function f(x) = 1/x. Division by 0 is undefined, so this restricts our domain to all real numbers except 0.

A key feature of our problem is in the exponents - are there any exponents that would limit the possible values of x? Let's strip away the rest of the details and just look at those powers for each option:

For A, let's look at the function [tex]f(x) = x^{1/5}[/tex]. Remember that fractional exponents are the same as roots, so we could also say [tex]f(x)=\sqrt[5]{x}[/tex]. Any odd root like this can take any value for x, positive and negative. This has to do with the fact that any odd power of a negative is always negative. So no restrictions on A.

For B, just looking at the exponent, let's see if there are restrictions on the function [tex]k(x) = x^{1/2}[/tex]. Again, we can rewrite the right side as a root: [tex]k(x) = \sqrt{x}[/tex].

Unline f(x), k(x) is restricted. The square root of a negative number has no real solutions, so k(x) comes with the restriction that x ≥ 0. We could look at C and D, but we've already found our solution at this point, so I'll stop here!

Answer: 3

PLOT AT THE POINT (-1, 3)

Step-by-step explanation:

Just plug in the X coordinate in the equation to get the answers.

Example in problem 2

Plug in X to find Y

Y= -1^2 + 2

Y = 3

Therefore, graph it at the point (-1,3)

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.
