Answer:
PQ and RS are parallel to each other
Step-by-step explanation:
Slope of two points (x1,y1) and (x2,y2) is given by
slope = (y2-y1)/(x2-x1)
for two lines to be parallel slope should be equalfor two lines to be perpendicular product of slope should be -1_______________________________________________Lets find the slope of PQ and RS
for PQ P(2, -1), Q(-3,-1), R(-11, 9), S(-7, 9)
slope PQ = (-1 -(-1))/(-3 -2) = (-1 + 1)/5 = 0/5 = 0
Slope RS = (9-9)/(-7 - (-11) ) = 0/4 = 0
Since
slope PQ = slope RS = 0
Hence PQ and RS are parallel to each other
A rental car agency charges a flat fee of $32.00 plus $3.00 per day to rent a certain car. Another agency charges a fee of $30.50 plus $3.25 per day to rent the same car.
Answer:
a rental car agency charges a flat rate fee of $32.00 plus $3.00 per day to rent a certain car
c = 32 + 3d
another agency charges a fee of $30.50 plus $3.25 per day to rent the same car
c = 30.50 + 3.25d
the number of days for which the cost are the same means
32 + 3d = 30.50 + 3.25d
by solving we find d = 6 days
Which exponential function is the best fit for the data in the table? ( please help! )
Multiply
g(x) = x2 + 3x
h(x) = 2x - 2
Find (g* h)(2)
Answer:
10
Step-by-step explanation:
At first, (goh)(x)= g{h(x)}
= g{2x-2}
={2x-2}^2 +3x
[tex] = 4 {x}^{2} - 8x + 4 + 3x \\ = 4 {x}^{2} - 5x + 4 \\ then \: \:(goh)(2) = 4 \times {2}^{2} - 5 \times 2 + 4 \\ = 16 - 10 + 4 \\ = 10[/tex]

Answer: Converse: If the candy has 350 calories, the candy is chocolate, False. There is another 350 calorie candy.
Inverse: If the candy does not have 350 calories, the candy is not chocolate. True In this case, the evidence in the chart supports this. The inverse is not always true.
Contrapositive: If the candy does not have 350 calories, the candy is not chocolate. True The evidence in the chart supports this statement, and the Contrapositive is generally considered a logical equivalent of the original.
Step-by-step explanation:
You need to have a basic frame for converting the original statement to the other forms such as
Original: If P, then Q
Converse: If Q, then P Just reverse the parts
Inverse: If not P then not Q In the same order, make both negative, add "not"
Contrapositive: If not Q then not P Reverse the order of the original and make both negative.

Answer:
y-4=3/2(x+4)
Step-by-step explanation:
If you plug the numbers into the equation (y-y1=m(x-x1)), you get y-4=3/2(x+4).
Answer: y=3/2x+13
Step-by-step explanation: y-4=3/2(x-(-6))
y-4=3/2x+9
y=3/2x+13

Many companies use a quality control technique called acceptance sampling to monitor incoming shipments of parts, raw materials, and so on. In the electronics industry, component parts are commonly shipped from suppliers in large lots. Inspection of a sample of n components can be viewed as the n trials of a binomial experiment. The outcome for each component tested (trial) will be that the component is classified as good or defective. Reynolds Electronics accepts a lot from a particular supplier if the defective components in the lot do not exceed 1%. Suppose a random sample of five items from a recent shipment is tested.
a. Assume that 1% of the shipment is defective. Compute the probability that no items in the sample are defective.
b. Assume that 1% of the shipment is defective. Compute the probability that exactly one item in the sample is defective.
c. What is the probability of observing one or more defective items in the sample if 1% of the shipment is defective?
d. Would you feel comfortable accepting the shipment if one item was found to be defective? Why or why not?
Answer:
A. 0.9510
B. 0.0480
C. 0.0490
D. No, I would not feel comfortable accepting the shipment if one item was found defective, because the probability is quite small to obtain 1 or more defective items.

You can just multiply the bottom equation by 2 and it would cancelled out the ys.
Answer:
Elimination
Step-by-step explanation:
It is elimination because when you eliminate you are adding or subtracting to get one variable. For example, you would do 10y-5y= 5y and 14 + 4 = 18

8=2+3d u got to get d. i need this asap
Answer:
d = 2
Step-by-step explanation:
8 - 2 = 6
6 / 3 = 2
plz mark brainliest
Answer:
d=2
Step-by-step explanation:
Switch the left and right sides
2+3d=8
Rearrange the expression
3d+2=8
Separate the constants and variables
3d=8−2
Add or subtract the numbers
3d=6
divide both sides by 3
3d/3=6/3
d=2

Answer:
look for the LCM of all the denominators, devide the denominators by the LCM and add the numerators( don't forget the signs ), then add and subtract your answers ( by this time the LCM becomes the denominator and the answer from th subtraction and addition of the numerators becomes the present numerator ), then reduce to lowest term the answer gotten

Step-by-step explanation:
Given: PS=RT, PQ=ST
Prove: QS=RS
Answer:
I) Eq(1) reason: sum of segments of a straight line
II) Eq(2) reason: Given PQ = ST & PS = RT
III) Eq(3) reason: sum of segments of a straight line
IV) Eq(4) reason: Same value on right hand sides of eq(2) and eq(3) demands that we must equate their respective left hand sides
V) Eq(5) reason: Usage of collection of like terms and subtraction provided this equation.
Step-by-step explanation:
We are given that;
PS = RT and that PQ = ST
Now, we want to prove that QS = RS.
From the diagram, we can see that from concept of sum of segments of a straight line we can deduce that;
PQ + QS = PS - - - - (eq 1)
Now, from earlier we saw that PQ = ST & PS = RT
Thus putting ST for PQ & PS for RT in eq 1,we have;
ST + QS = RT - - - - (eq 2)
Again, from the line diagram, we can see that from concept of sum of segments of a straight line we can deduce that;
RS + ST = RT - - - - -(eq 3)
From eq(2) & eq(3) we can see that both left hand sides is equal to RT.
Thus, we can equate both left hand sides with each other to give;
ST + QS = RS + ST - - - (eq 4)
Subtracting ST from both sides gives;
ST - ST + QS = RS + ST - ST
This gives;
QS = RS - - - - (eq 5)
Thus;
QS = RS
