Answer:
-3 <x <-1
Step-by-step explanation:
|x + 2| < 1
There are two solutions, one positive and one negative ( remember to flip the inequality for the negative)
x+2 <1 and x+2 > -1
Subtract 2 from each side
x+2-2 < 1-2 and x+2-2 > -1-2
x < -1 and x >-3
-3 <x <-1
Determine the value of x.

Barry has 17 more than two-thirds of the number of cards in his brother's baseball card collection. If x represents the number of baseball cards his brother has, which expression represents the number of baseball cards Barry has? Two-thirds x minus 17 Two-thirds x + 17 17 x minus two-thirds 17 x + two-thirds
Answer:
B. Two-thirds x + 17
Step-by-step explanation:
Let
x = number of baseball cards his brother has
two-thirds of the number of cards in his brother's baseball card collection = 2/3x
Barry = 2/3x + 17
A. Two-thirds x minus 17
= 2/3x - 17
B. Two-thirds x + 17
= 2/3x + 17
C. 17 x minus two-thirds
= 17x - 2/3
D. 17 x + two-thirds
= 17x + 2/3

write down five numbers so that the mean is 6 the median is 5 and the mode is 4
Answer:
4,4,5,7,10
Step-by-step explanation:
this can be
4,4,5,7,10
5 is in the middle because 5 is median
4 appeared thrice cause it is the mode
and 10 is just there to give us our mean 6 because it is only 30/5 that gives 6 so we have to find 5 numbers whose sum gives 30
Answer:
The 5 numbers can be: 4, 4, 5, 8, 9.
Step-by-step explanation:
In 4, 4, 5, 8, 9. 5 is the median (The middle number).
The mode is 4 because 4 is the most repeated number.
(4+4+5+8+9)/5 is equal to 30/5 which equals 6. So, 6 is the mean.
Hope this helps! :)
If a car is moving on a straight line with a velocity of 40 m/s and it changes its velocity to 60 m/s in 4 seconds, calculate its acceleration.
Answer:
5m/s²
Step-by-step explanation:
Given :-
Initial Velocity = 40m/s Final velocity = 60 m/sTime = 4sTo Find :-
The acceleration .Solution :-
We know that the rate of change of velocity is called acceleration. Therefore ,
[tex]\sf\implies a = v - u / t \\ [/tex]
[tex]\sf\implies a = 60m/s - 40m/s/ 4 \\ [/tex]
[tex]\sf\implies a = 20m/s \div 4 \\[/tex]

Solve the following pair of linear equations using substitution method :-
2x+3y + 5 = 0 ; 5x-3y+9=0
Answer:
(- 2, - [tex]\frac{1}{3}[/tex] )
Step-by-step explanation:
Given the 2 equations
2x + 3y + 5 = 0 → (1)
5x - 3y + 9 = 0 → (2)
Rearrange (1) expressing 3y in terms of x by subtracting 2x + 5 from both sides
3y = - 2x - 5
Substitute 3y = - 2x - 5 into (2)
5x - (- 2x - 5) + 9 = 0 ← distribute parenthesis on left side and simplify
5x + 2x + 5 + 9 = 0
7x + 14 = 0 ( subtract 14 from both sides )
7x = - 14 ( divide both sides by 7 )
x = - 2
Substitute x = - 2 into either of the 2 equations and solve for y
Substituting into (1)
2(- 2) + 3y + 5 = 0
- 4 + 3y + 5 = 0
1 + 3y = 0 ( subtract 1 from both sides )
3y = - 1 ( divide both sides by 3 )
y = - [tex]\frac{1}{3}[/tex]
solution is (- 2, - [tex]\frac{1}{3}[/tex] )

A new car sells for $25,000. The value of the car decreases by 15% each year. What is the approximate value of the car 5 years after it is purchased? 25,000 (1 minus 0.15) Superscript 5, or approximately $11,093 25,000 minus 1500 (5), or approximately $17,500 25,000 (0.15) Superscript 5, or approximately $18,984 25,000 minus left-bracket (100 minus 15) (5) Right-bracket, or approximately $24,575
Answer:
A. 25,000 (1 minus 0.15) Superscript 5, or approximately $11,093
Step-by-step explanation:
A. 25,000 (1 minus 0.15) Superscript 5, or approximately $11,093
B. 25,000 minus 1500 (5), or approximately $17,500
C. 25,000 (0.15) Superscript 5, or approximately $18,984
D. 25,000 minus left-bracket (100 minus 15) (5) Right-bracket, or approximately $24,575
Value of the car = $25,000
Percentage decrease per year = 15%
Value after 5 years
Total percentage value of the car = 100%
Percentage value remaining each year = (100% - 15%)
= (1 - 0.15)
Decrease of the car in the next 5 years = $25,000(1 - 0.15)^5
= $25,000(0.85)^5
= $25,000(0.4437053125)
= $11,092.6328125
Approximately = $11.093
Value of the car in the next 5 years = $25,000 - $11,093
= $13,907
Answer:
It's A, $11,093

given g(x) = square root of x - 4 and h(x) = 2x - 8 What is g(h10))?
Step-by-step explanation:
First find h(10)
h(10)=2(10)-8
h(10)=12
Now plug in 12 as the value of x in g(x) ie.g(12)
So g(12)=√12-4=√8=2√2
