Answer:
X=1, x= -3, x= -1/2
Step-by-step explanation:
okay, so you've got your zeros right here actually. it's very simple, so I'll give you the reader's digest: SET THEM ALL TO ZERO
x-1=0 add your one, so that's x=1
x+3=0, subtract your 3, so that's x= -3
the last one is tricky: 2x+1=0, 2x= -1, but you can go further. divide your two, and you're left with x= -1/2
I hope this helps!!!

Answer:
Bushes are $9.
Bonsai trees are $32.
Step-by-step explanation:
Bushes are b and bonsai trees are t.
15b + 8t = $391
9b + 5t = $241
15b + 8t = $391 × 3 and 9b + 5t = $241 × 5
= 45b + 24t = $1173 and 45b + 25t = $1205
(45b + 24t = $1173) - (45b + 25t = $1205)
t = 1205 - 1173
t = $32
Apply to 15b + 8t = $391.
15b + 32 × 8 = $391
15b = $391 = 32 × 8
15b = $391 - 256
15b = $135
x = ($135 ÷ 15) = $9

Serge was curious if a sample third quartile was an unbiased estimator of a population third quartile. He started with a large normally distributed population of test scores whose third quartile was Q3=80 points. He then took a random sample of 6 tests and calculated the third quartile of the sample. He replaced those tests and repeated this process for a total of 40 trials. His results are summarized in the dot plot below, where each dot represents the third quartile from a sample of 6 tests.
Answer:
Sample third quartile appears to be an unbiased estimator of the population third quartile.

Drag graphs to show a graph of each equation in the table.
Answer:
Step-by-step explanation:
- The # in front of x will be the number that hits on the y-axis
- The # after x or the slope, ex: y = -1/2x + 2, is how much you move to hit the next point on the graph
- 2 would actually be 2/1 so move up 2 and right 1 (if the number or fraction is negative then go up and to the left
- So y = -2x - 1/2, negative slope. Start at -2 on y-axis and go up 1 then left 2.

Answer:
The smaller number is 12 & greater number is 15.
Answer:
12
Step-by-step explanation:
let the numbers be x and y and x>y
x-y=3
x+y=27
add
2x=30
x=30/2=15
15+y=27
y=27-15=12

Of Linear Eqitions by
Elimination
3x-y=0
2x+y=-10
Answer:
(-2, -6)
Step-by-step explanation:
Given the simultaneous equation
3x-y=0 ... 1
2x+y=-10 ... 2
Add both equations to eliminate y
3x + 2x = 0 - 10
5x = -10
x = -10/5
x = -2
Substitute x = -2 into 1
3(-2)- y = 0
-6 - y = 0
-y = 0+ 6
-y = 6
y = -6
Hence the coordinate (x, y) is (-2, -6)
Algebra 2!! What is the domain of the function graphed below?
Answer:
(-infinity,+infinity)
Step-by-step explanation:
Domain refers to the x-axis. So if we look from left to right along the x-axis we could conclude that the function will go infinitley from negative infinite to positive infinity.

what is the value of x in the equation 24 equals 12 - 4x
Answer:
x = -3
Step-by-step explanation:
24 = 12 - 4x
24 - 12 = -4x
12 = -4x
12/-4 = x
x = -3
Answer:
x=-3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
24=12−4x
24=12+−4x
24=−4x+12
Step 2: Flip the equation.
−4x+12=24
Step 3: Subtract 12 from both sides.
−4x+12−12=24−12
−4x=12
Step 4: Divide both sides by -4.
−4x
−4
=
12

x=−3

Find the quotient
6 1/2 divided by 3/4
Answer:
8 2/3
Step-by-step explanation:
First, we turn 6 1/2 into an improper fraction, which is 13/2. Now, we can write this out as: 13/2 divided by 3/4. When dividing fractions, you reverse the sign to multiplication and you flip the numerator and the denominator of the second number. So, in this case, it would be 13/2 TIMES 4/3 which now we can do! 13*4 is 52 and 2*3 is 6. 52/6 is a number we can simplify. We can divide out a 2, so 52/2 is 26 and 6/2 is 3. 26/3 can be put into a mixed number. 3 goes into 26, 8 times and there is a 2 left over. So our final answer is 6 2/3.
