The inequality is easy because an inequality says,
y > mx + b (This is just an example)
m = slope
b = y- intercept
What about the sign?
If the circle in the graph which is at the y-intercept (b) is OPEN than it's either < or > depending on where it's going, if it's going to the right on a number line than it's >, however if it goes left than it's <.
What about the AND EQUAL TO sign?
Well same rules apply, however if the circle is CLOSED than it should be ≤ or ≥, same rules apply, if it goes right or left it's the same rule the only thing that changes is the and equal to, if circle is closed.
Example:
slope: 1/2
y-intercept: -9 (and the line is shaded to the right)
Open circle:
Equation: y > 1/2x - 9
Example 2:
slope: 3/4
y-intercept: -9 (is shaded to the left (less than))
(shaded)Closed circle:
Equation: y ≤ 3/4x - 9

Answer:
assuming that you want us to add them together here's the answer i got-
5y²−3y+3
Step-by-step explanation:
let us simplify step-by-step-
4y²−2y−5+y²(−y)+8
= 4y²+(−2y)+(−5)+y²+(−y)+8
combining like terms-
=4y²+−2y+−5+-y²+−y+8
=(4y²+y²)+(−2y+−y)+(−5+8)
=5y²+−3y+3

Answer:
[tex]VW = 50[/tex]
Step-by-step explanation:
Given
The attached triangle
Required
Find VW
To find VW, we make use of the following equivalent ratios.
[tex]YX : XW = ZX : XV[/tex]
Where:
[tex]YX = ZX - ZY = 42 - 28 = 14[/tex]
[tex]XV = XW + VW = 25 + VW[/tex]
So, we have:
[tex]14 : 25 = 42 : 25 + VW[/tex]
Express as fraction
[tex]\frac{14 }{ 25 }= \frac{42 }{ 25 + VW}[/tex]
Divide both sides by 14
[tex]\frac{1}{ 25 }= \frac{3}{ 25 + VW}[/tex]
Cross multiply
[tex](25 + VW) * 1 = 3 * 25[/tex]
[tex]25 + VW = 75[/tex]
Solve for VW
[tex]VW = 75 -25[/tex]
[tex]VW = 50[/tex]

Answer:
2x² + 7x - 4
Step-by-step explanation:
(2x + 1)(x + 4)
Each term in the second factor is multiplied by each term in the first factor, that is
2x(x + 4) - 1 (x + 4) ← distribute parenthesis
2x² + 8x - x - 4 ← collect like terms
= 2x² + 7x - 4

A physical trainer has four workouts that he recommends for his clients. The workouts have been designed so that the average maximum heart rate achieved is the same for each workout. To test this design he randomly selects twenty people and randomly assigns five of them to use each of the workouts. During each workout, he measures the maximum heart rate in beats per minute with the following results.
Maximum Heart Rates (Beats per Minute)
Workout #1 Workout #2 Workout #3 Workout #4
172 184 178 170
182 169 166 194
179 185 160 196
154 165 174 192
155 178 179 182
Requird:
a. Can the physical trainer conclude that there is a difference among the average maximum heart rates which are achieved during the four workouts?
b. Find the value of the test statistic to test for a difference between the workouts.
Solution :
ANOVA : Single factor
Groups [tex]$\text{count}$[/tex] [tex]$\text{Sum}$[/tex] [tex]$\text{Average}$[/tex] [tex]$\text{Variance}$[/tex]
Workout 1 5 842 168.4 174.3
Workout 2 5 881 176.2 79.7
Workout 3 5 857 171.4 66.8
Workout 4 5 934 186.8 117.2
ANNOVA
Source of Variance SS df MS F P-value F crit
Between groups 976.2 3 325.4 2.971689 0.063098 3.238872
Within groups 1752 16 109.5
Total 2728.2 19
The null hypothesis is : [tex]$u_1=u_2=u_3=u_4$[/tex]
Alternative hypothesis : At least one of the [tex]$u$[/tex] is not equal.
The significance level = 0.05
Analyzing the sample data:
F statistics is given by :
[tex]$F=\frac{MSB}{MSE}$[/tex]
= 2.97
[tex]$F_{critical}=3.24$[/tex]
The P-value= 0.06
The result : Since the P-value of 0.06 is greater than the significance level (0.05), hence we fail to reject the null hypothesis.
So we cannot conclude that there is no difference between the average maximum heart rates that are achieved during the four workouts.
A survey was given to people who own a certain type of car. What percent of the people surveyed were completely satisfied with the car?
Answer:
65 percent
Step-by-step explanation:
The solution is 65 %
The percentage of people who were satisfied with the car is 65 %
What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the percentage of people who were satisfied with the car be = P
Now , the number of people who were satisfied with the car = 1625
The number of people who were somewhat satisfied with car = 665
The number of people who were not satisfied with the car = 210
The total number of people surveyed = number of people who were satisfied + number of people who were somewhat satisfied + number of people who were not satisfied
Substituting the values in the equation , we get
The total number of people surveyed = 1625 + 665 + 210
The total number of people surveyed = 2500 people
So , the percentage of people who were satisfied with car P = number of people who were satisfied with the car / total number of people surveyed
Substituting the values in the equation , we get
Percentage of people who were satisfied with car P = ( 1625 / 2500 ) x 100
Percentage of people who were satisfied with car P = 0.65 x 100
Percentage of people who were satisfied with car P = 65 %
Therefore , the value of P is 65 %
Hence , the percentage is 65 %

Find the value of x in the triangle shown below 6 2
The value of x in the stated triangle is 6.32 based on given dimensions.
The stated triangle is right angled triangle and hence will follow Pythagoras theorem. The calculation will be done using the Pythagoras formula as stated -
Perpendicular² = Base² + Height²
Keep the values in formula to find the value of x
x² = 2² + 6²
Taking square on the Right Hand Side of the equation
x² = 4 + 36
Add the digits on Right Hand Side of the equation
x² = 40
x = ✓40
Taking square root
x = 6.32
Hence, the length of x is 6.32.

Answer:
y = -2x + 11
Step-by-step explanation:
Slope point equation:
y - y1 = m(x -x1)
y1 = 7 ; x1 = 7 , m = -2
y - 7 = -2(x - 2)
y - 7 = -2x -2*(-2)
y -7 = -2x + 4
y = -2x + 4 + 7
y = -2x + 11
