Which shows a quadratic function?
Answers
Answer:
OPTION B IS YOUR ANSWER.
You know its a quadratic when the second difference of each y value is same.
Here's what I mean.
Option B
First all x values differ by 1. So we're good on those.
Now for the y values
Which are
3, -1, -3, -3, -1
find the difference between the second and first fod each... Then do this a second time.
If it gives the same value for all the second differences... Then its quadratic.
-1-3 = -4
-3-(-1) = -3 + 1 = -2
-3-(-3) = -3 + 3 = 0
-1-(-3) = -1 + 3 = 2.
The values are -4, -2, 0, 2.
Now find the difference of these(2nd - 1st)
-2-(-4) = -2 + 4 = 2
0-(-2)= 0 + 2 = 2
2 - 0 = 2
Since all second differences gave 2 as their answer....
Option B is your Quadratic Function!!!

ſ 2y = x - 4
4x + 3y = 5
Answers
Answer:
X=2, y=-1
Step-by-step explanation:
2y=x-4 equation 1
4x+3y=5 equation 2
x=2y+4 isolate x in equation 1
4(2y+4)+3y=5 substitute value of x from equation 1 into equation 2
8y+16+3y=5
11y=-11
y=-1
solve for x by inputting y value into either equation
2y=x-4

-2=x-4

Two adjacent angles form an obtuse angle measured 164°. If m<1 = 3x+5 and m<2= 5x+9, find the measurement of the larger angle. Plz help and don't answer if you don't know for sure :) thxx
Answers
Answer:
102.75
Step-by-step explanation:
The two angles add to 164
<1 + <2 = 164
3x+5 + 5x+9 = 164
Combine like terms
8x+14 = 164
Subtract 14 from each side
8x+14-14 =164-14
8x = 150
Divide by 8
8x/8 = 150/8
x = 18.75
The larger angle is 5x+9 = 5(18.75) +9 =102.75

Answer:
x = 32
Step-by-step explanation:
All interior angles in a triangle equal to 180
use this to solve for x
180 = 85 + 63 + x
180 - 85 - 63 = x
32 = x
Luis put out 6 different pies at a picnic at the end of the picnic, he noticed this about the pies: one whole apple pie was eaten, and 3/4 of another apple pie was eaten 1/2 of the blackberry pie was eaten 1/8 of the blueberry pie was eaten 5/8 of the cherry pie was eaten 3/4 of the peach pie was eaten. What is the total amount of pies that where left over
Answers
Answer:
2 1/4
Step-by-step explanation:
amount left of apple pie = 1 - 3/4 = 1/4
amount left of blackberry pie = 1 - 1/2 = 1/2
amount left of blueberry pie = 1 - 1/8 = 7/8
amount left of cherry pie = 1 - 5/8 = 3/8
amount left of peach pie = 1 - 3/4 = 1/4
add this figures together
1/4 + 1/2 + 7/8 + 3/8 + 1/4

Max claims that a point on any line that is perpendicular to a segment is equidistant from a segment's endpoints. Charlene claims that the line must be a perpendicular bisector for a point on the line to be equidistant from a segment's endpoints.
Answers
Answer:
Charlene claim is true.
Step-by-step explanation:
Max claims that a point on any line that is perpendicular to a segment is equidistant from a segment's endpoints.
It is not necessary as shown in the diagram (a).
Charlene claims that the line must be a perpendicular bisector for a point on the line to be equidistant from a segment's endpoints.
It is true as shown in the diagram (b).
So, Charlene claim is true.
A grocery store has a sale on apples. Shoppers can buy 3 bags of apples for $5. Each bag contains 6 apples. Which of the following statements is true?
Answers
Answer:
i dont know
Step-by-step explanation:
Answer:
D.
Step-by-step explanation:
3b = 5$
3b = 6a
3b = 3 bags
6a = 6 apples
A. It costs 3.60 for 1 bag of apples
3.60 + 3.60 = 60 + 60 = 120 + 3 = 123 + 3 = 126
Meaning it would cost 126 for 3 bags of apples making this a incorrect option
B. It costs 3.60 for 1 apple
B is wrong because its one apple and if we were to subtract the apple would probably only cost a few change not 3$ and 60 cents.
C. The cost of 9 bags of apples is 30$
9b = 21a, its either c or d but I'm pretty sure its D!
D. The cost of 108 apples is 30$
D is correct

Answer:
A = 28.26 C = 18.84
Step-by-step explanation:
1/2(d) = 1/2(6) = 3
3 is the radius/r
π is said to be in this equation as 3.14
Calculate Area:
A = 1/4πd^2
A = 1/4(π6^2)
A = 1/4(π36)
A = 1/4(113.04)
A = 28.6
Calculate Circumference:
C = 2πr
C = 2(π3)
C = 2(9.42)
C = 18.84

bank reduces the interest rate from 12% p.a. to 10% p.a to expand its business. By how much is the yearly interest on Rs. 8,400 decreased?
Answers
Answer:
$168
Step-by-step explanation:
yearly interest = principal x time x interest rate
interest when interest rate is 12% = 8400 x 0.12 = 1008
interest when interest rate is 10% = 8400 x 0.1 = 840
decrease in interest rate = 1008 - 840 = 168

we get 0.4117...
convert that to a percentage and we have 41% markup
