Answer:
f(-2) = 2
Step-by-step explanation:
Look at the graph and find -2 on the x-axis and see what the y-coordinate is on the line where x is -2. When you do this, you can see that where x is -2, y is 2.
So basically it wants the y-value :)

Answer:
The answer is the first option that states that you can write this expression as [tex]7(\frac{x}{8}) + \frac{3}{4} = -6[/tex]
Step-by-step explanation:
In order to solve this question we will need to know how to factor fractions. In our case we can do the following.
[tex]\frac{7}{8}x = \frac{7x}{8} = 7(\frac{x}{8})[/tex]
So now we since [tex]\frac{7}{8} x= 7(\frac{x}{8} )[/tex] ⇒
⇒ [tex]\frac{7}{8}x + \frac{3}{4} = -6[/tex]
[tex]7(\frac{x}{8}) + \frac{3}{4} = -6[/tex]

The probability of event A occurring is 0.65. The probability of events A and B occurring together is 0.33. Events A and B are independent. What is the probability of event B?
Answer:
1-0.65 = 0.35 I think the probability of B is 0.35
Step-by-step explanation:
Answer: Approximately 0.51
======================================================
Explanation:
If events A and B are independent, then P(A and B) = P(A)*P(B) is a true equation.
We're given the following
P(A) = 0.65P(A and B) = 0.33So,
P(A and B) = P(A)*P(B)
0.33 = 0.65*P(B)
P(B) = 0.33/0.65
P(B) = 0.5076923076923
which is approximate. When we round to 2 decimal places, we get 0.51

Answer:
what is l and multiply l by 4 my guy
Step-by-step explanation:
Answer:
x = 25
<HKL = 102
Step-by-step explanation:
<LKH + <HKJ = 180 since the two angles form a straight line
<LKH + <HKJ = 180
4x+2 + 78 = 180
Combine like terms
4x+80 =180
Subtract 80 from each side
4x+80-80=180-80
4x= 100
Divide by 4
4x/4 = 100/4
x = 25
<LKH = 4x+2 = 4*25 +2 = 100+2 = 102

Madeline has to earn at least 80 points for her science fair project. So far on the rubric she has 64 points. What is the minimum number of points that Madeline needs to earn?
F. x ≥ 96
G. 96 ≥ x
H. x ≤ 16
J. 16 ≤ x
The solution is : she needs at least 16 points.
x + 64 ≥ 80
x ≥ 16
What is inequality?An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.
here, we have,
Given
Madeline has to earn at least 80 points for her science fair project. So far on the rubric she has 64 points.
so,
Total = 80 (at least)
accumulated = 64
Required
Express as an inequality
In inequalities, at least means ≥
So, the expression is:
Where x represents the additional points
x + 64 ≥ 80
Solve for x
x ≥ 16
Hence, she needs at least 16 points.

The MagicSoft software company has a proposal to the city council of Alva, Florida, to relocate there. The proposal claims that the company will generate $3.3 million for the local economy by the $1 million in salaries that will be paid. The city council estimates that 70% of the salaries will be spent in the local community and 70% of that money will again be spent in the community, and so on. What is the correct estimate of the amount generated to the local economy?
Answer:
The correct estimate of the amount generated to the local economy is $3,333,333.[tex]\bar3[/tex]
Step-by-step explanation:
The amount the expected to be generated for the local economy = $3.3 million
The amount of salaries that will generate $3.3 million = $1 million
The percentage of the amount of the salaries and the subsequent earnings expected to be spent on the local community = 70%
Therefore, we have;
For a first amount of 1 million into the economy, the next amount to into the economy is 70/100 × 1 million = 700,000, then we have 70/100 × 700,000 and so on, which is a geometric sequence, with first term, a = $1 million, the common ratio, r = 70/100 = 0.7, the number of terms = Infinity = ∞
The sum of a geometric sequence to infinity is given as follows;
[tex]\sum\limits_{k = 0}^{\infty }a \cdot r^k = S_{\infty} = \dfrac{a}{1 - r}[/tex]
Substituting the known values gives;
[tex]\sum\limits_{k = 0}^{\infty }1,000,000 \times 0.7 ^k = \dfrac{1,000,000}{1 - 0.7}= 3,333,333.\bar 3[/tex]
Therefore, the correct estimate of the amount generated to the local economy by the $1 million salaries that will be paid = $3,333,333.[tex]\bar3[/tex].

4x + 9 = 2x + 15 .. I need help
Answer:
x = 3
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
4x + 9 = 2x + 15
Step 2: Solve for x
Subtract 2x on both sides: 2x + 9 = 15Subtract 9 on both sides: 2x = 6Divide 2 on both sides: x = 3Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 4(3) + 9 = 2(3) + 15Multiply: 12 + 9 = 6 + 15Add: 21 = 21Here we see that 21 does indeed equal 21.
∴ x = 3 is the solution to the equation.

Find the equation of the line
PLEASE HELP
Answer:
y = -3x +7
Step-by-step explanation:
The equation for a line is: y = mx + b
m = slope
x = the x-value
y = the y-value
b = the y-intercept
Since the y-intercept is 7, we know the first part of the equation is: y = mx +7
Also, since the line is decreasing from right to left, m is going to be negative. A way to calculate the m is rise/run. Count how many blocks it is going horizontally (run)and how many blocks it is increasing/decreasing when going to the right (rise). Then divided the "rise" over "run". Another way is to choose two points. Now use the equation y1-y2/x1-x2,
or y2-y1/x2-x1. I am going to show using the equation.
My two points are (0,7) and (2,1)
change in y (rise):7-1 = 6
change in x (run): 0-2 = -2
6/-2 = -3. Your slope is -3. Now lets put it all together.
y = -3x +7
You can see that for every square moved to the right ONCE the y value is decreasing by 3 each time.
Write the slope-intercept form of the equation that is described below.
Through (-3, 3) and parallel to y = 1/3x + 5
Final Answer: [tex]y = \frac{1}{3}x + 4[/tex]
Steps/Reasons/Explanation:
There are two methods of solving this problem. Slope-intercept form and Point-slope form. I will be using the Slope-intercept form to solve this problem.
Step 1: Substitute slope from the original line ([tex]\frac{1}{3}[/tex] in this case) into the slope-intercept equation.
[tex]y = \frac{1}{3}x + b[/tex]
Step 2: Substitute the given point [tex](-3, 3)[/tex] into the x and y values.
[tex]y = \frac{1}{3}x + b[/tex]
[tex]3 = \frac{1}{3}(-3) + b[/tex]
Step 3: Solve for b (the y-intercept).
[tex]3 = \frac{1}{3}(-3) + b[/tex]
[tex]3 = -1 + b[/tex]
[tex]+1[/tex] = [tex]+1[/tex] [tex]+[/tex] [tex]b[/tex]
[tex]4 = b[/tex]
Step 4: Substitute this value for b in the slope-intercept form equation.
[tex]y = \frac{1}{3}x + 4[/tex]
~I hope I helped you :)~
Answer:
y = 1/3x + 5
Step-by-step explanation:
(-3, 3)
x , y
x1 = -3
y1 = 3
The formula we will use is y - y1 = m ( x - x1)
We will now replace y1 and x1 with the coordinate points (-3, 3).
We will keep x1 = -3, and y1 = 3.
then you will plug in the numbers giving you an equation like:
y - (3) = 1/3 (x -(-3))
y - 3 = 1/3 (x + 3)
y - 3 = 1/3x +1
+ 3 + 3
y = 1/3x + 4
I am 100% sure I am correct.

tommy had 8 times more money than loren. when parents gived 35cents to loren and tommy spent 14cents both of kids had same money. how much tommy had in start? how much loren had in start?
Answer:
Tommy had 56 cents in start and Loren had 7 cents in start.
Step-by-step explanation:
Let,
x be the money Tommy have.
y be the money Loren have.
According to given statement;
Tommy had 8 times more money than Loren.
x = 8y Eqn 1
Parents gave 35 cents to Loren and Tommy spent 14 cents, therefore
x-14=y+35 Eqn 2
Putting x=8y in Eqn 2
[tex]8y-14=y+35\\8y-y=35+14\\7y=49[/tex]
Dividing both sides by 7
[tex]\frac{7y}{7}=\frac{49}{7}\\y=7[/tex]
Putting y=7 in Eqn 1
[tex]x=8(7)\\x=56[/tex]
Hence,
Tommy had 56 cents in start and Loren had 7 cents in start.
