Answer:
b = 2 or b = -2Explanation:
|4b + 4| = |2b + 8|
Solve absolute value
|4b + 4| = |2b + 8|
Either 4b + 4 = 2b + 8 or 4b + 4 = −(2b + 8)
4b + 4 = 2b + 8 (Possibility 1)
4b + 4 − 2b = 2b + 8 − 2b (Subtract 2b from both sides)
2b + 4 = 8
2b + 4 − 4 = 8 − 4 (Subtract 4 from both sides)
2b = 4
2b / 2 = 4 / 2 (Divide both sides by 2)
b = 2
4b + 4 = −(2b + 8) (Possibility 2)
4b + 4 = −2b − 8 (Simplify both sides of the equation)
4b + 4 + 2b = −2b − 8 + 2b (Add 2b to both sides)
6b + 4 = −8
6b + 4 − 4 = −8 − 4 (Subtract 4 from both sides)
6b = −12
6b / 6 = -12 / 6 (Divide both sides by 6)
b = -2
b = 2 or b = -2Can someone help with 8 and 9

- 5x + 2y = 9
y = 7x
Answer:
x = 1Explanation:
- 5x + 2y = 9
y = 7xInsert 7x For 'y'- 5x + 2(7x) = 9
Remove Parenthesis-5x + 2 · 7x = 9
Multiply: 2 · 7 = 14-5x + 14x = 9
Add: -5x + 14x = 9x9x = 9
Divide Both Sides By 99x ÷ 9 = 9 ÷ 9
x = 1

The number of years it will take for $510 to grow to $1,010.18 at 5 percent compounded annually is ____
Answer:
13.66 years
Step-by-step explanation:
Given data
P=$510
A=$1,010.18
R=5%
t= ln(A/P)/r
susbstitute
t= ln(1,010.18/510)/0.05
t=ln1.980/0.05
t= 0.683/0.05
t= 13.66
Hence the time is 13.66 years

A jar of coins has 8 pennies, 5 nickels, 1 dime, and 7 quarters. What is the probability of drawng a quarter, replacing it, and drawing another quarter.
Given:
A jar of coins has 8 pennies, 5 nickels, 1 dime, and 7 quarters.
To find:
The probability of drawing a quarter, replacing it, and drawing another quarter.
Solution:
A jar of coins has 8 pennies, 5 nickels, 1 dime, and 7 quarters.
Total number of coins = 8+5+1+7 = 21
Probability of getting a quarter is
[tex]P(Quarter)=\dfrac{\text{Number of quarters}}{\text{Total number of coins}}[/tex]
[tex]P(Quarter)=\dfrac{7}{21}[/tex]
[tex]P(Quarter)=\dfrac{1}{3}[/tex]
After drawing a quarter, we replaced it. So, the probability of getting quarter in second draw is the same and first one, .i.e., [tex]P(Quarter)=\dfrac{1}{3}[/tex].
The probability of drawing a quarter, replacing it, and drawing another quarter is
[tex]P=\dfrac{1}{3}\times \dfrac{1}{3}[/tex]
[tex]P=\dfrac{1}{9}[/tex]
Therefore, the required probability is [tex]\dfrac{1}{9}[/tex].

Answer:
4. supplementary
5. complementary
Step-by-step explanation:
4 is supplementary because the sum of the two angles is 180°.
5 is complementary because the sum of the two angles is 90°.
Answer:
4. Supplementary
Supplementary angles sum up to 180 degrees.
105 degrees + 75 degrees = 180 degrees
5. Complementary
Complementary angles sum up to 90 degrees.
30 degrees + 60 degrees = 90 degrees

Answer:
For 17 the first answer is 1(1/20). The picture can be misleading because the flags are at the same height and the American flag's pole looks shorter. This is only because it is behind the Floridian flag and because the perspective isn't accurate to compare them.
Step-by-step explanation:
The mixed fraction would be 1(5/100) which can be simplified when you divide the fraction by 5 into 1(1/20).

Slope is –2, and (5, 3) is on the line.
To be put into slope intercept form
i wish that i could help you but I just dont understand it... I am sorry
Answer: putting that in slope intercept form : y=-2x+10
Step-by-step explanation:
slope intercept form is y=mx+b.
m= the slope
the slope you gave us is -2
b= the y intercept
a y intercept is the coordinate that touches/crosses the y axis.
to find the y intercept, use the slope (rise over run) you will eventually cross the y axis at 10.
y=-2x+10

Select all expressions that show x increased by 15%. A. 1.15x B. x+15/100x C.15/100x D. (1+0.15)x E.(100+15)x
HELP NOW
9514 1404 393
Answer:
A, B, D
Step-by-step explanation:
"x increased by 15%" means "x plus 15% of x".
This can be written several ways.
x + 15%x . . . . . . a direct translation
x + 15/100x . . . . matches choice B
x +0.15x . . . . . . with the percentage as a decimal
(1 +0.15)x . . . . . . matches choice D
1.15x . . . . . . . . . . matches choice A
_____
Additional comment
It can be helpful to remember that % is a shorthand way to write /100. That is ...
15% = 15/100
It can also be helpful to remember place value:
15/100 = "fifteen hundredths" = 0.15

Find the circumference of each circle. Use your calculator's value of p. Round your answer to the nearest tenth.
please helppppppppppppppppppppp
Answer: The circumference is 33.284 cm
Step-by-step explanation:
The equation to find the circumference use the fomula to find it.
3.14 is the simplified version of Pi (I SUGGEST TO USE YOUR CALCULATOR)
C = 2*pi*R /// Circumference = 2 times pi times Radius.
C = 2 * 3.14 * 5.3
C = 6.28 * 5.3
C = 33.284

93 is the sum of a number g and 58.
Answer:
G is 35.
Step-by-step explanation:
You can make the equation 93 = g + 58. In order to find the variable g, you have to isolate it. So you can subtract 93 by 58 and you get 35. To double check your work, just plug in your answer in g.
93 = 35 + 58
93 = 93 ✔️
The answer is 35.

angle 9 and angle 10 are corresponding and complementary angles formed by two parallel lines cut by a transversal. find m angle 9
Answer:
45 degrees
Step-by-step explanation:
if <9 and <10 are corresponding, it means they are equal i.e <9 = <10
Since <9 and <10 are also complementary angles, their sum will be 90 degrees
<9+<10 = 90
<9 + <9 = 90
2m<9 = 90
m<2 = 90/2
m<2 = 45 degrees
Hence the measure of angle 9 is 45 degrees

16. Hanna has a bag of 23 marbles. 5 marbles are red, 6 marbles are blue, and the rest
are pink. Abby takes out two pink marbles without replacing them. What is the
probability that the next marble he draws will be blue?
A. 10/21
B. 4/21
C. 2/7
D. 6/23
Answer:
C. 2/7
Step-by-step explanation:
When two pink marbles are taken without replacement then the total number of marbles in the bag are reduced to 21 marbles. So the blue marble, which are currently in total 6 marbles, is taken out of the total of 21 marbles. The calculation of which is done as below:
Probability of Next Marble to be blue
= Blue Marble / Total Marbles in the bag
= 6 / 21
= 2 / 7
Hence, the correct option is C. 2/7
