How do I find out what X equals?
Answer:
10. x ≥ 2
11. x > 6
12. 1 ≤ x < 5
Step-by-step explanation:
With greater/less than or equal to (≤ or ≥) think about the line closing it off and shading it in.
With regular greater/less than, there is no line so it is an open circle.

Answer:
the formula for the area of a triangle is a= b*h/2
Step-by-step explanation:
area= base* height divided by two.
if a triangles base was 5 height was 4 the area would be 10units
5*4=20

Write an equation of the line that had a slope of -2 and passes through (4,-2)
Need help ASAP!!
Answer:
The equation is y = -2x + 6.
Step-by-step explanation:
Given that the slope-form equation is y = mx + b and the gradient is -2. So you have to find the value of b by substituting the coordinates into the equation :
[tex]y = mx + b[/tex]
[tex]let \: m = - 2,x = 4,y = - 2[/tex]
[tex] - 2 = - 2(4) + b[/tex]
[tex] - 2 = - 8 + b[/tex]
[tex]b = 6[/tex]
[tex]y = - 2x + 6[/tex]
Thomas took three 100-point quizzes, and the mean score for the three quizzes was 87 points. If the highest score is taken away, the mean of the remaining two scores would be 83.5 points. If the lowest score is taken away, the mean of the remaining two scores would be 89 points. What is the highest score?
Answer:
The highest score is 94.
Step-by-step explanation:
Let the highest score be denoted by, A, the lowest score be, B and the middle score be X.
Then,
A + X + B = 87 × 3 = 261 ...(i)
X + B = 83.5 × 2 = 167 ...(ii)
⇒ B = 167 - X ...(iii)
A + X = 89 × 2 = 178 ...(iv)
⇒ A = 178 - X ...(v)
Substitute (iii) and (v) in (i) and solve for X as follows:
A + X + B = 261
178 - X + X + 167 - X = 261
345 - X = 261
X = 84
Substitute the value of X in (iii) and solve for B as follows:
B = 167 - X
= 167 - 84
= 83
Substitute the value of X in (v) and solve for A as follows:
A = 178 - X
= 178 - 84
= 94
Thus, the highest score is 94.
The tables show the statistics of a running back in a football game did he gain more than 50 yards total? Explain .
Answer:
He gained more than 50 yards in the game.
Step-by-step explanation:
Running back in the first quarter in a football game = -8.5 yards
Running back in second quarter = 23 yards
Running back in 3rd quarter = 42.5 yards
Running back in 4th quarter = -2.25 yards
Total gain in the game = -8.5 + 23 + 42.5 - 2.25 = 54.75 yards
That means he gained more than 50 yards in the game.

Xander goes to the movies with his soccer team. Each team member buys a ticket and two
boxes of popcorn. There are 13 team members.
Let t represent the cost of a ticket and p represent the cost of a box of popcorn.
a) Write two different expressions that represent the total amount the team spent.
b) Explain how each expression describes the situation in a different way.
Given that, the cost of a ticket = t and
cost of a box of popcorn = p.
Total members in the team = 13
As each team member buys 1 ticket and 2 boxes of popcorn, so, the amount spent by one member, [tex]C_1 = t+2p[/tex]
So, the total amount that the team spent [tex]= 13C_1[/tex]
(a) So, the first expression, representing the total amount spent by the team, is
[tex]13\times (t+2p)\cdots(i)[/tex]
On simplification, the second expression, representing the total amount spent by the team, is
[tex]13\timest + 13\times (2p)[/tex]
[tex]=13t+26p\cdots(ii)[/tex]
(b) The expression from the equation (i) represent the total amount spent as 13 times the expenses of one member, while equation (ii) is the sum of two terms where the first term, 13t, represents the total amount spent for buying the ticket and the second term, 26p, represents the total amount spent for buying popcorn

Define a variable and write an algebraic expression for each problem. Evaluate the expression for the given values. 1. The charge for ice skating is $3 for skate rental and $2 per hour to skate. How much will you pay if you skate for: a) 2 hours? b) 4 hours? c) 3 1/2 hours?
Answer:
Amount = 3 + 2t
Amount pay for 2 hours = $7
Amount pay for 4 hours = $11
Amount pay for 2 hours = $10
Step-by-step explanation:
Given:
Fixed charges = $3
Variable charges = $2 per hour
Find:
Amount pay
a) 2 hours? b) 4 hours? c) 3 1/2 hours?
Computation:
Assume time = t
So,
Amount = 3 + 2t
Amount pay for 2 hours = 3 + 2t = 3 + 2(2) = $7
Amount pay for 4 hours = 3 + 2t = 3 + 2(4) = $11
Amount pay for 2 hours = 3 + 2t = 3 + 2(3 1/2) = $10
So
12(4x -1/4x ) 2 + 5(4x-1/4x) - 2

What would be the range for {(-6, 4), (5, -1), (0, 3), (-2, 4)}
Answer: {4, -1, 3}
Explanation: The range is the set of all y-coordinates for our ordered pairs.
So the range for this relation is 4, -1, 3, 4.
Notice that we have two 4's as y-coordinates
but we only need to mention the 4 once.
So our range is {4, -1, 3}.

The graph will stretch vertically and horizontally
The graph will stretch vertically making it look thinner
The graph will not change
The graph will shrink vertically making it look fatter
Advance topics
Answer:
The graph is being stretched vertically, so it will be thinner.
Step-by-step explanation:
g(x) = 8f(x) means that you are multiplying each original y-value by 8, so the graph gets thinner. When there's a number n greater than 1 in front of the function, it's a vertical stretch by n.

What is the purpose of the AutoSum feature in Microsoft® Excel? A. To automatically add all numbers in all cells in a workbook B. To add a list of numbers in a spreadsheet C. To put a list of numbers in order before finding the sum D. To estimate the total of a list of numbers
Answer:
B. To add a list of numbers in a spreadsheet
Step-by-step explanation:
AutoSum feature in Microsoft Excel is used to automatically sum up a range of numbers within a horizontal row or vertical column without having to input a formula.
When a range of numbers are selected within a row or column, clicking on AutoSum will sum up the numbers in the adjacent empty cell. For example, if you wanted to add the values of cells between B1 and B10, highlight cells B1 through B10 and click the AutoSum button . The sum of B1 to B10 will be given in B11.
In Excel 2010 and later, the AutoSum feature is on the Home tab, in the Editing section.

A high school basketball team won exactly 65 percent
of the games it played during last season. Which of
the following could be the total number of games the
team played last season?
A) 22
B) 20
C) 18
D) 14
Answer: B) 20 games
Step-by-step explanation: 65/100X20=13 this is the only whole number
Using percentages, it is found that the total number of games the team played last season could have been of 20, given by option B.
The team won exactly 65% of their games, thus, 65% of the number of games has to be an exact number.
Finding 65%(multiplying by 0.65) of the possible number of games given:
[tex]22(0.65) = 14.3[/tex]
[tex]20(0.65) = 13[/tex]
[tex]18(0.65) = 11.7[/tex]
[tex]14(0.65) = 9.1[/tex]
Only 65% of 20 results in an exact number, thus B is the correct option.

Answer:
SR is 17, using the side, angle, side rule of congruency.
Step-by-step explanation:
Triangle SRV is congruent to triangle STV, so SR would be equal to ST, which is 17. Since SV creates a right angle when it bisects RT, we know the they both share a right angle. We also know that the the side created by SV is the same for both. Since they told us that RV equals VT, we know that the triangles are congruent by the SAS (side angle side) rule. Hope this helps!
