How many solutions does the equation 4x 8 = − 2 − 2 5x have? two one zero infinitely many
Answers
The equation 4x + 8 = -2 - 2 + 5x has one solution
How to determine the number of solutions?The equation is given as:
4x + 8 = -2 - 2 + 5x
Collect like terms
4x - 5x = -2 - 2 - 8
Evaluate the like terms
-x = -12
Divide both sides by -1
x = 12
The above means that the equation 4x + 8 = -2 - 2 + 5x has one solution

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10.
If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

so, when 1 gallon = 3.79 liters, then how much is 4 gallons ?
4 gallons is 4 times 1 gallon. so, of course, we need to apply the same factor to the other side too.
4 gallons = 4×3.79 = 15.16 ≈ 15 liters
and e do the same for all the other table elements :
8 liters = 8×0.26 = 2.08 ≈ 2 gallons
12.5 liters = 12.5×0.26 = 3.25 ≈ 3 gallons
6 gallons = 6×3.79 = 22.74 liters ≈ 23 liters

Step-by-step explanation:
An absolute value graph is a V-shaped graph(in yellow, see image) You can use "transformations of parent functions" to graph it (high school/college) OR use a table of values (middleschool/hs). The - 2 that's in the parenthesis with the x causes the graph to slide to the RIGHT 2 units. (shown in green) The green graph is what you are asking for.
If you aren't learning about translations (which means shift or slide and is a type of transformation) then you can just make a table of values. Pick several x's and put them in the equation and find out what y's go with them. Plot the points on the graph and connect. See image.

You only have $2.42 left. Daisy cost $2.35 and Rose cost $2.55
Jimmy is playing a game at a state fair, where he is throwing a dart at a target. For each throw, Jimmy can choose to throw the dart at a rectangular target or at a circular target. To score a point during the game, Jimmy must hit the bulls-eye of the target that he chooses. So far, Jimmy has thrown the dart at the rectangular target 9 times, and he has thrown the dart at the circular target 11 times.
When Jimmy has thrown the dart at the rectangular target, he has missed the bulls-eye 6 times. When Jimmy has thrown the dart at the circular target, he has missed the bulls-eye 9 times.
Based on the information above, if Jimmy's goal is to score a point on his next throw, which target should he choose?
Answers
Using proportions, it is found that Jimmy should target the rectangular target, as he has hit a higher proportion of throws there.
What is a proportion?A proportion is a fraction of a total amount.
In the rectangular target, he has hit it 3 out of 9 times, hence the proportion is:
pR = 3/9 = 0.3333.
In the circular target, he has hit it 2 out of 11 times, hence the proportion is:
pC = 2/11 = 0.1818.
Due to the higher proportion of hits, he should throw at the rectangular target.

9-4 = 5 (the minus value come from 4n^2 where n is the position where 9 lays)
24-16 = 8
47-36 = 11
so plus 3 every time so 3n
4n^2+3n for the first value is 7 so you need an extra 2
4n^2+3n+2
The quadratic sequence is 4n² + 3n + 2.
What is a quadratic sequence?The difference between words always varies by the same amount, which is a characteristic of quadratic number sequences. The "difference between the differences between the words in the sequence is always the same" as a result. The second difference is referred to as constant.

The given sequence is a quadratic sequence.
The given terms are: 9 24 47 78 117
The difference between the first three consecutive terms:
9 24 47
15 23
Difference of difference:
8
and 8/2 = 4
∴ The first term is 4n²
9-4 = 5 (the minus value come from 4n² where n is the position where 9 lays)
24-16 = 8
47-36 = 11
so plus 3 every time
∴ The second term to add is 3n
4n² + 3n for the first value is 7, so you need an extra 2
∴ The third term to add is 2
4n² + 3n + 2
Hence, the quadratic sequence is 4n² + 3n + 2

What is the slope of the line whose equation is -2y = -4x + 5
Answers
Answer:
2
Step-by-step explanation:
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-2*y-(-4*x+5)=0
STEP 1:
Pulling out like terms
1.1 Pull out like factors :
-2y + 4x - 5 = -1 • (2y - 4x + 5)
Equation at the end of step 1:
STEP 2:
Equation of a Straight Line
2.1 Solve -2y+4x-5 = 0
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line -2y+4x-5 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 5/-2 so this line "cuts" the y axis at y=-2.50000
y-intercept = 5/-2 = -2.50000
Calculate the X-Intercept :
When y = 0 the value of x is 5/4 Our line therefore "cuts" the x axis at x= 1.25000
x-intercept = 5/4 = 1.25000
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is -2.500 and for x=2.000, the value of y is 1.500. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 1.500 - (-2.500) = 4.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 2
Geometric figure: Straight Line
Slope = 2
x-intercept = 5/4 = 1.25000
y-intercept = 5/-2 = -2.50000
Answer:
2
Step-by-step explanation:
y=mx+b where m is the slope
to get y by itself you divide both sides by -2 resulting in
y= 2x+(-5/2)
2=m

Given P(A) = 0.55, P(B) = 0.42 and P(AUB) = 0.639, find the value of
P(An B), rounding to the nearest thousandth, if necessary.
Answers
Answer:
The probability of A and B, denoted as P(A ∩ B) is equal to 0.331.
Step-by-step explanation:
Recall our formula for the probability of A or B:
P(A ∪ B) = P(A) + P(B) - P(A ∩ B)We are given are variables already, which we can once again define:
P(A) = 0.55P(B) = 0.42P(A ∪ B) = 0.639To find P(A ∩ B), we start by plugging in the values into our formula:
0.639 = 0.55 + 0.42 - P(A ∩ B)We can add the RHS of the equation:
0.639 = 0.97 - P(A ∩ B)Subtracting 0.97 on both sides, we get closer to our answer:
-0.331 = -P(A ∩ B)To obtain our final answer, we can simply just divide both sides by -1:
0.331 = P(A ∩ B)P(A ∩ B) = 0.331Therefore, the probability of A and B is equal to 0.331.

Answers

Step-by-step explanation:
2 hours and 5 minutes = 2 + 5/60 hours = 2 5/60 hrs
63 miles / (2 5/60) = 30.24 m/hr
Step-by-step explanation:
To find the average speed, we must know this formula :
[tex] \\ {\longrightarrow\sf \qquad{Average \: speed = \dfrac{Distance \: Travelled}{Total \: Time \: Taken}}} \\ \\ [/tex]
Also we know that, 2 hr 5 min = 2.083 hrs approximately so,Now, substituting the given values in the formula :
[tex] \\ {\longrightarrow\sf \qquad{Average \: speed = \dfrac{63 \: miles}{2.083 \: hr}}} \\ \\ [/tex]
[tex] \\ {\longrightarrow\sf \qquad{Average \: speed = 30.24 \: mph}} \\ \\[/tex]

Soft drinks sell for P8.50 and fruit juice sells for P11.00 each. On a certain day, the number of soft drinks sold was four times the number of fruit juice sold. How many soft drinks were sold if the total income was P900.00?
Answers
The number of soft drinks sold was 4 times the number of fruit juice -> On average, every 4 soft drinks sold, 1 fruit juice is.
-> Every P34.00 of soft drinks sold, P11.00 of fruit juice is.
So, the income is P45.00 everytime.
Since the total income is P900.00, the amount of 4 soft drinks and 1 fruit juice sold is 900 : 45 = 20 times
So, there were 20 x 4 = 80 soft drinks sold.
Recheck : 80 x 8.5 + 20 x 11 = 680 + 220 = 900.
