Answer:
1. x = 2/3y + 8/3
2. x=−y+1
Step-by-step explanation:
Solve for x
3x−2y=8
Add 2y to both sides.
3x−2y+2y = 8+2y
3x=2y+8
Divide both sides by 3.
3x/3 = 2y+8/3
x = 2/3y + 8/3
Answer:
x = 2/3y + 8/3
#2
solve for x.
x+y=1
Add -y to both sides.
x+y+−y=1+−y
x=−y+1
Answer:
x=−y+1
solve for y.
x+y=1
Add -x to both sides.
x+y+−x=1+−x
y=−x+1
Answer:
y=−x+1

which sequence of rigid transformations will map the preimage ABC onto image A'B'C'?
Answers
The sequence of rigid transformations that will map the preimage ΔABC onto image ΔA'B'C' is Option(a) a reflection across the x-axis, a translation 8 units right, and then a reflection across the x-axis.
What is the sequence of rigid transformations?There are three basic rigid transformations: reflections, rotations, and translations.Reflections, as the name implies, mirror the given shape over a particular line. Translations slide or shift a shape from one location to another, whereas rotations spin a shape about a predetermined center point.Co-ordinates of the points of ΔABC are,
A = (-4, 2)
B = (-6, 2)
C = (-2, 6)
point (x,-y) is the reflection of the point (x,y) across the x-axis.
So, new co-ordinates are,
A = (-4, -2)
B = (-6, -2)
C = (-2, -6)
point (x+8,y) is the translation of the point (x,y) by 8 units right.
So, new co-ordinates are,
A = (4, -2)
B = (2, -2)
C = (6, -6)
Then, the reflection of the point (x,y) across the x-axis is the point (x,-y).
So, new co-ordinates are,
A' = (4, 2)
B' = (2, 2)
C' = (6, 6)
These are the coordinates of ΔA'B'C' so the correct answer is Option(a).

Clyde and mason each leave a rest area on the flordia turnpike. Clyde travels north and mason travels south. After 4 hr, Clyde has gone 248 mi and mason, who ran into heavy traffic, traveled only 184 mi. How far apart are they
Answers
Clyde and Mason are 432 mi apart from each other in distance.
We are given that:
Clyde and mason can each leave a rest area on the Florida turnpike.
Clyde travels north whereas Mason travels south.
After 4 hr., we get that Clyde has gone 248 mi and Mason, due to the heavy traffic he got , traveled only 184 mi.
We need to tell how far are they from each other.
We will do this by addition.
Distance = 248 mi + 184 mi
Distance = 432 mi.

A number cube with the numbers 1 through 6 is rolled. The probability of rolling an odd or even number is 1. What is the likelihood of rolling an odd or even number?
Answers
1/2 is the likelihood of rolling an odd or even number in probability.
What is probability and how is it calculated?
According to the probability formula, the probability of an event occurring, or P(E), is equal to the proportion of positive outcomes to all outcomes. P(E) is defined mathematically as favorable outcomes divided by total outcomes.A probability is a numerical representation of the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.The event "rolling an odd number" contains three outcomes. There are 6 equally likely outcomes in the sample space. Divide to find the probability of the event.

Evaluate 2X^2 + 3X -10 for the domain of {-2, 3}
Answers
The values of the expression at the domain {-2, 3} are {-8, 4}
How to evaluate the expression for the domain?The expression is given as
2x^2 + 3x - 10
The domain of the function is given as
{-2, 3}
Rewrite the domain as
x = {-2, 3}
Next, we substitute these values of x in the expression 2x^2 + 3x - 10
So, we have
x = -2:⇒ 2(-2)^2 + 3(-2) - 10 = -8
x = 2:⇒ 2(2)^2 + 3(2) - 10 = 4
Hence, the values of the expression at the domain {-2, 3} are {-8, 4}

Cherries cost 4 dollars per pound.my mother r lb of cherries and my father bought 2 lb of cherries.how much more money did my mother spent on cherries than my father
Answers
Mother spent (4r - 8) dollars more on cherries than did the father.
An expression using numbers and related operations is called a numerical expression.
According to the question, a pound of cherries costs $4.
Mom purchased r pounds.
The price of the cherry is calculated as follows: 4r = weight x $/lb.
Father purchased 2 pounds, thus the price of the cherries is 4 (2), or $8.
We remove the smaller value from the higher value, which is 4r - 8, where r must be more than two. Given that the mother spent more money on cherries than the father, the mother's cost of cherries is a greater value.

Answers
The digit 8 in Carla’s number represents 10 times of what the digit 8 represents in Travis’ number.
The number written by Carla = 814,247
The number written by Travis = 683,571
The place value of digits starting from left is ones, ten's, hundreds, thousands, ten thousand, hundred thousand and so on.
As per this sequence of values, we can see that digit 8 in Carla's number is at hundred thousand place value. Also, digit 8 in Travis' number is at ten thousand place value. So, representing these place value in numeral form and finding the number of times one is greater than other.
Digit 8 in Carla's number: 100,000
Digit 8 in Travis' number: 10,000
Finding the answer -
Value = 100,000 ÷ 10,000
Cancelling common zeroes from numerator and denominator
Value = 10
Hence, digit 8 in Carla’s number represents 10 times of what the digit 8 represents in Travis’ number.

P and Q
We are also given the distance between the two points P and Q is:
PQ = 10 units.
Now we have that Q lies at 13.
We have to find the location of P.
We know that
Distance = P ± Q
10 = P ± 13
so, we get that
10 = P + 13 or 10 = P - 13
P = 10 - 13 or P = 13 + 10
P = -3 or P = 23
Therefore, we get that the point P can either lie at - 3 or at 23.

Answers
Answer:
21
Step-by-step explanation:
You want the value of the expression 2f(-3)-f(4), given that f(x) = 3x²-x+ 5.
Function evaluationA function is evaluated by putting the argument where the variable is, and simplifying the result. Polynomials are often easier to evaluate if they are written in Horner form.
f(x) = 3x² -x +5
f(x) = (3x -1)x +5
The values we need are ...
f(-3) = (3(-3) -1)(-3) +5 = (-10)(-3) +5 = 35
f(4) = (3(4) -1)(4) +5 = (11)(4) +5 = 49
Then the expression of interest has the value ...
2f(-3) -f(4) = 2(35) -49 = 70 -49
2f(-3) -f(4) = 21

The gas mileeage in miles per gallon is 44.69 miles per gallon
How to convert 19 Km/L to miles per litresWe'll begin by converting 19 Km/L to miles per litres. This can be obtained as follow:
Gas mileage (in Km/L) = 19 Km/LGas mileage (in mile per litres) =?1 Km/L = 0.621371 mile per litre
Therefore,
19 Km/L = (19 Km/L × 0.621371 mile per litre) / 1 Km/L
19 Km/L = 11.806 miles per lire
How to convert 11.806 miles per litre to miles per gallonWe can convert 11.806 miles per litre to miles per gallon as follow:
1 mile per litre = 3.78541178 miles per gallon
Therefore,
11.806 miles per litre = (11.806 miles per litre × 3.78541178 miles per gallon) / 1 mile per litre
