I really don’t get this , it’s graphing linear inequalities
The first step in graphing a linear inequality is to graph the linear equality. The equation -x + 4y = -8 is equivalent to 4y = x - 8, which is equivalent to [tex]y = \frac{1}{4}x - 2[/tex]. This is the equation for the line in slope-intercept form, so the line will have a slope of 1/4 and a y-intercept of -2 (see the first image). Notice that the line is solid, rather than dotted. This represents that points on the line are included in the solution, because the inequality sign is ≥, which is not a strict equality (< or >).
Next, we need to figure out which side to shade. To do so, simply pick any point (I like to use the point (0,0) because it makes the calculations easy) and see whether it satisfies the inequality. If it does, shade the side with that point, and if not, shade the opposite side of the graph.
Here we see that the point (0,0) does satisfy the inequality, since -(0) + 4(0) is 0, and 0 ≥ -8, so the top half of the graph should be shaded (see the second image).
Type the number only. What is the measure of ∠w?

You and your family are driving to the wild animal Park in Escondido California the distance from your house to the park is 528 miles. You hope to get there in 8 hours of driving time. What would be your average driving speed?
Answer:
66 miles per hour.
Step-by-step explanation:
Given that:
Distance between house to Wild Animal Park = 528 miles
Expected time to be taken in the travel = 8 hours
To find:
Average speed of the travel = ?
Solution:
First of all, let us have a look at the formula for Average Speed of any travel.
Let [tex]D[/tex] be the total distance traveled in any travel and
[tex]T[/tex] be the total time taken in this travel
Then Average Speed, [tex]S[/tex] is given by the formula:
[tex]S = \dfrac{D}{T}[/tex]
OR
[tex]Average\ Speed = \dfrac{Total\ Distance\ Traveled}{Total\ Time\ Taken}[/tex]
Here, we are given that:
[tex]D[/tex] = 528 miles
[tex]T[/tex] = 8 hours
[tex]S = \dfrac{528}{8}\\\Rightarrow S = \bold{66\ miles/hr}[/tex]
Therefore, the average speed is 66 miles/hr.

One rectangle is devided into four parts. How much is one part?
Answer:
[tex]P = \¼R[/tex]
Step-by-step explanation:
Given
Shape: Rectangle
Division = 4 parts
Required
How much is one part of the division
Represent the rectangle with R and the parts with P
When a rectangle (R) is divided into 4 parts (P); the relationship between R and P is:
[tex]P = \frac{R}{4}[/tex]
[tex]P = \¼R[/tex]
This implies that the one part of the division is ¼ of the divided rectangle

Answer:
x = -4 (and btw that is so cuteee)
Step-by-step explanation:
Points: (-4,-1) and (-4,-5)
m = y2 - y1/x2 - x1
m = (-5) - (-1)/(-4) - (-4)
m = -5 + 1/-4 + 4
m = -4/0

Answer:
product of powerspower of a powernegative exponentStep-by-step explanation:
The value in square brackets is evaluated using the product of powers rule:
(7^5)(7^3) = 7^(5+3) = 7^8
Then the overall value is found using the power of a power rule:
[7^8]^-4 = 7^(8(-4)) = 7^-32
Finally, the expression value is found using the negative exponent rule:
7^(-32) = 1/7^32 = 1/1104427674243920646305299201

Each number you started out with has 1 space between the last number and the decimal, so your final answer will have 2 spaces.
Also, since you multiplied a negative and a positive, your final answer will be negative.

For a craft project, Jackie cuts the two triangles described below out of fabric. Find the length of CE¯¯¯¯¯¯¯¯.
In triangle CDE, CD¯¯¯¯¯¯¯¯=7 cm, CE¯¯¯¯¯¯¯¯=(4z+7) cm, ∡C=48°, and ∡E=82°. In triangle TUV, UV¯¯¯¯¯¯¯¯=(13z−20) cm, UT¯¯¯¯¯¯¯=7 cm, ∡U=48°, and ∡V=82°.
Answer: ???
Answer:
19
Step-by-step explanation:
took the test
Given:
In triangle CDE, CD=7 cm, CE=(4z+7) cm, ∡C=48°, and ∡E=82°.
In triangle TUV, UV=(13z−20) cm, UT=7 cm, ∡U=48°, and ∡V=82°.
To find:
The length of CE.
Solution:
In triangle CDE and triangle UTV,
[tex]m\angle C=m\angle U[/tex] (Given)
[tex]m\angle E=m\angle V[/tex] (Given)
[tex]CD=UT[/tex] (Given)
Two angles and a non -included side are equal in both triangle. So, both triangles are congruent by AAS postulate.
[tex]\Delta CDE\cong \Delta UTV[/tex]
[tex]CE=UV[/tex] (CPCTC)
[tex]4z+7=13z-20[/tex]
[tex]4z-13z=-7-20[/tex]
[tex]-9z=-27[/tex]
Divide both sides by -9.
[tex]z=3[/tex]
Now,
[tex]CE=4(3)+7[/tex]
[tex]CE=12+7[/tex]
[tex]CE=19[/tex]
Therefore, the length of CE is 19 cm.
If country A has 161,950,000 more computers than country B and the total number of computers for both countries is 319,250,000 find the number of computer for each country
Answer:
The number of computers in country A and country B is 78,650,000 and 240,600,000 respectively
Step-by-step explanation:
The computation of the number of computer for each country is as follows:
Let us assume the computer in country B is x
So, in country A it is x + 161,950,000
And, the sum of them is
x + x + 161,950,000 = 319,250,000
2x + 161,950,000 = 319,250,000
2x = 319,250,000 - 161,950,000
2x = 157,300,000
x = 78,650,000
So, the country B, the computers are 78,650,000
And, in country A it is 78,650,000 + 161,950,000 = 240,600,000

How to add two fractions?Let we have to add two fractions as:
[tex]\dfrac{a_1}{b_1} + \dfrac{a_2}{b_2}[/tex]
Then we will find Lowest Common Multiple (LCM) of b_1 and
b_2. That will help to make the denominators same.
Once the denominators become same, the numerators can add up directly, giving us the final result of addition.
Given;
y-5/3=1
Solution;
y=5/3+1
or y=5/3+1/1
taking LCM of denominators;
y=(5+3)/3
y=8/3
