Answer:
D. {1, 12}
Step-by-step explanation:
4X^2-52x+169=121
The equation can be summarized thus:
4X^2-52x+169-121=0
4X^2-52x+48=0
divide the each number of the equation by 4
4X^2/4-52x/4+48/4=0
x^2-13x+12=0
we need to numbers that when we multiply them the result is 12 and -13 when we add together
-1 and -12(-1-12=-13 and -1*-12=12)
x^2-x-12x+12
x(x-1)-12(x-1)
(x-1)(x-12)
x-1=0 or x-12=0
x=1 or x=12

From a barrel of colored marbles, you randomly select 1 blue 6 yellow 7 red 4 green and 6 purple marbles
Complete question :
From a barrel of colored marbles, you randomly select 1 blue 6 yellow 7 red 4 green and 6 purple marbles. Find the experimental probability of randomly selecting a marble that is NOT yellow.
Answer:
Step-by-step explanation:
Total number of marbles :
Blue = 1 ; yellow = 6 ; red = 7 ; green = 4 ; purple = 6
Total = (1 + 6 + 7 + 4 + 6) = 24 marbles
Probability of selecting marble that is not yellow :
Number of marbles that aren't yellow / total number of marbles
Marbles that aren't yellow = 24 - 6 = 18
P(selecting a marble that isn't yellow) = 18 / 24 = 3/4

Which ordered pairs are solutions to y = x + 1?
A (0,1),(1,2), (2,3)
B (0, -1), (2, -1), (3,-2)
C (0,1),(1,2), (2, 4)
D (0,1),(2, 1), (3, 1)
Answer:
A. ( 0, 1 ), ( 1, 2 ), ( 2, 3 )
Step-by-step explanation:
( x, y ) = ( 0, 1 )
Here,
x = 0
y = 1
y = x + 1
1 = 0 + 1
1 = 1
( x, y ) = ( 1, 2 )
Here,
x = 1
y = 2
y = x + 1
2 = 1 + 1
2 = 2
( x, y ) = ( 2, 3 )
Here,
x = 2
y = 3
y = x + 1
3 = 2 + 1
3 = 3
3 dogs plus 5 cats cost $365. 5 dogs plus 3 cats cost $491. What is the cost of one cat?
Answer:
Solution given;
let dogs be d and cats be c.
according to the question
3 d +5 c =$365........[1]
5d+3c=$491.............[2]
By doing elimination method
multiplying equation 1 by 5 and equation 2 by 3 and subtracting
we get
15d+25c=$365*5
15d+9c=$491*3

Answer: 5x -16
20X
Step-by-step explanation:
Simplify 4/5x
Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
5x - (4 • 4) 5x - 16
———————————— = ———————

Answer:
B. y = 85x
Step-by-step explanation:
First, find the rate of change of the graph:
Rate of change = change in y/change in x
Using two points (0, 0) and (4, 300),
Rate of change (m) = (300 - 0)/(4 - 0) = 300/4
Rate of change (m) = 75
Compare this with the rate of change of the given equations in the options.
✔️Option A: y = 65x + 100
The rate of change of this equation is 65, which is less than the rate of change of the given graph (75)
✔️Option B: y = 85x
The rate of change of this equation is 85, which is greater than the rate of change of the given graph (75)
✔️Option B: y = 50x + 150
The rate of change of this equation is 50, which is less than the rate of change of the given graph (75)
✅Therefore, the equation that has a greater rate of change than the one shown in the graph is y = 85x

Step-by-step explanation:
The distance between 2 and 4 is 2.
2 + 2 = 4
The width is 2 units.
The distance between - 3 and 5 is 8.
- 3 + 8 = 5 or 8 - 3 = 5
4 + 8 + 4 + 8 = 24

In 1990, the population of the U.S. was about 250 million and was growing exponentially
at a rate of about 1% per year. At this rate, in what year will the population have
doubled?
a. 2080
b. 2070
c. 2060
d. 2050
Answer:
The correct answer is C.
Step-by-step explanation:
Giving the following information:
Present Value (PV)= 250 million
Future Value (FV)= 500 million
Growth rate (g)= 1% per year
First, we need to calculate the number of years required for the population to double:
n= ln(FV/PV) / ln(1+g)
n= ln(500/250) / ln(1.01)
n= 69.66 = 70 years
It will take 70 years for the population to double.

Answer:
I would say not here D.
Step-by-step explanation:
Because I found the area of the base first *the square* which is 4 x 11 = 44 and the rectangles are 4 x 14= 56 x 2 since there are 2 rectangles is 112. Then the triangles are 11x14=154/2=77 x 2 since there are 2 triangles is 154. Then we add up all those numbers 44+112+154= 310 not 308 *C*.

Andy estimated that he would need 73 feet of lumber for a tree house project. He later found that the actual amount of lumber needed was 62 feet. What was the percent error of Andy's estimation?
Answer:
17.74%
Step-by-step explanation:
The formula for percent error is given as:
|Estimated value - Actual value|/Actual value × 100
From the above question:
Estimated value = 73 feet
Actual value = 62 feet
Hence,
Percent error = |73 - 62|/62 × 100
= 11/62 × 100
= 17.741935484%
Approximately , percent error = 17.74%
Therefore, the percent error of Andy's estimation is 17.74%
