Can someone please show me how to solve (-6)=-x+b with steps?
Answer:
x = 6+b
Step-by-step explanation:
-6 = -x+b
Subtract b from each side
-6-b = -x+b-b
-6-b = -x
Multiply each side by -1
6+b = x

turn 5/9 into a decimal.
5/9 to a decimal would be .5 repeated
The answer is .5 repeated
Do not put your answer as .5 because .5 is 5/10

I need help finding x
Answer:
x = 40.3
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp / hyp
sin x = 11/17
Taking the inverse sin of each side
sin ^-1 ( sin x) = sin ^-1( 11/17)
x = 40.32
Rounding to the nearest tenth
x = 40.3
Answer:
45°
Step-by-step explanation:

How many gallons of a 70% antifreeze solution must be mixed with 90 gallons of 15% antifreeze to get a mixture that is 60% antifreeze? Use the six-step method.
Answer:
405 gallons
Step-by-step explanation:
Let it be that the amount of gallons of a 70% antifreeze solution is x, when a mixture that is 60 percents of antifreeze is placed in y gallons
x+90=y - the equation of dependence between solutions
The amount of antifreeze in the first one is x/100*70= 0.7x (in gallons), in the second solution (15percents) antifreeze is 90/100*15=13.5 (in gallons).
In the mixture we should get there will be y/100*60=0.6y - gallons of antifreeze
0,7x+13.5=0.6y
We have two equations x+90=y and 0,7x+13.5= 0.6y
0.6x+54=0.6y
0.7x+13.5=0.6y
0.7x+13.5-0.6x-54= 0.6y-0.6y
0.1x-40.5=0
x=405- the answer
p.s. sorry, I don't know what the six-step method is. But the answer is right.
Find the midline for f(x)=sinx+1.
a. y=0
B. y=−1
C. y=1
D. y=−2
Answer:
B Y=1
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
What is the greatest value that sin(x) + 1 can have? It isn't 1.
f(90) = sin(90) + 1
f(90) = 1 + 1 = 2
What is the smallest value that sin(x) + 1 can have? It still isn't one.
f(-90) = sin(-90) + 1
f(-90) = -1 + 1 = 0
So the midline is (2 + 0)/2 = 1
y = 1 is the answer.

The average price of a 0.5- carat round diamond is $3700 and the average price of a 0.75- carat diamond is $4950. If the weight and the price of the diamond is linearly related, how much will a 2.5 -carat round diamond cost?
Since the problem stated the weight and price are in a linear relationship, we can use y=mx+b.
First, let's calculate our slope.
m = (4950-3700)/(0.75-0.5) = 5000
Now, let's solve for b.
3700 = 5000(0.5) + b
Simplify the right side of the equation.
3700 = 2500 + b
Subtract 2500 from both sides
1200 = b
Now our equation looks like this:
y = 5000x + 1200
Let's plug 2.5 in for x to solve for the diamond cost.
y = 5000(2.5) + 1200
Simplify the right side.
y = 13700
The average price of a 2.5 carat diamond is $13700

if a shirt selling for $ 18 is marked up to $20 then the percentage increased is equal to
Answer:
11.11%
Step-by-step explanation:
the increased price = 20-18 = $2
the percentage increased = 2/18 ×100%
= 11.11%
Answer: Percent increase = 11.11%
Concept:
Here, we need to know how to find the percentage of increase.
Percent increase is a measure of percent change, which is the extent to which something gains value.
Percent increase = [(final value - initial value) / initial value] × 100%
Solve:
Given information
Initial value = $18
Final value = $20
Given expression
Percent increase = [(final value - initial value) / initial value] × 100%
Substitute values into the expression
Percent increase = [(20 - 18) / 18] × 100%
Simplify values in the parentheses
Percent increase = [2 / 18] × 100%
SImplify by multiplication
Percent increase = 11.11 % (Rounded to the hundredth place)
Hope this helps!! :)

When analyzing an argument, the first task is to identify its premise or premises and its conclusion. Conclusion indicators are words or phrases that can help you identify which statement in an argument is the conclusion.Each argument shown next uses a conclusion indicator. Identify the conclusion indicator and the argument's conclusion. Type the indicator word or phrase into the space provided, and then select which statement best represents the argument's overall conclusion.Argument ASilver cars are more likely to be pulled over than any other kind of car. This is because there are more silver-colored cars on the road than any other kind of car. Kari drives an average-looking silver car to and from work everyday. We may infer that Kari is more likely to be pulled over.From this argument, type the conclusion indicator word or phrase here:Which statement best represents the conclusion of the argument?Kari is more likely to be pulled over.Kari drives an average-looking silver car to and from work everyday.Silver cars are more likely to be pulled over than any other kind of car.There are more silver-colored cars on the road than any other kind of car.Argument BScissors are not a toy. If you run with scissors, then you could get hurt. You could poke your eye out or cut yourself with the scissors if you fall. For these reasons, you should never run with scissors.From this argument, type the conclusion indicator word or phrase here:Which statement best represents the conclusion of the argument?You could poke your eye out or cut yourself with the scissors if you fall.If you run with scissors, then you could get hurt.Scissors are not a toy.You should never run with scissors.Argument CWe know that the natural world is governed by scientific laws of regularity. Those laws express predictable relationships that do not allow any wiggle room for variant outcomes. So, humans do not have free will. This is because the human body is as much a part of the natural world as any other physical object.From this argument, type the conclusion indicator word or phrase here:Which statement best represents the conclusion of the argument?Humans do not have free will.The natural world is governed by scientific laws of regularity.The human body is as much a part of the natural world as any other physical object.Scientific laws express predictable relationships that do not allow any wiggle room for variant outcomes.
In Argument A the conclusion indicator is "we may infer that" and the conclusion is Kari is more likely to be pulled over.
In Argument B the conclusion indicator is "For these reasons" and the conclusion is You should never run with scissors.
In Argument C the conclusion indicator is "So" and the conclusion is Humans do not have free will.
To identify the conclusion of each argument, we can either separate the premises (examples of the author's opinion) from the entire argument or we can identify the conclusion indicators.
Some conclusion indicators include:
therefore, thus, hence, so, for these reasons, we may infer, as a result,consequently, etcArgument A:

**I answered 16 and it was wrong**
The value of the expression | m^2+n^2 | at m = -5 and n = 3 is 34.
Given,

Match the line described on the left with the slope of the line on the right. y = 3‐--------------------------------------undefined 9x – 3y = 18.--------------------------,------- - 2 the line through (5, 7) and (5, – 8) -------0 the line through ( – 4, – 1) and (-1,–7)--- 3.
Answer:
y=3, 0; 9x-3y=18, 3; line through (5, 7) and (5, – 8), undefined; the line through ( – 4, – 1) and (-1,–7), -2;
Step-by-step explanation:
y=3 is a horizontal line so the slope is 0
9x-3y=18 can be written as 3y=9x-18 or y=3x-6 so the slope is 3
the line through (5,7) and (5,-8) is a vertical line since the x value didnt change between the two points so the slope is undefined
we have to find the slope of the line through ( – 4, – 1) and (-1,–7). to do this use the formula (y_2-y_1)/(x_2-x_1)=(-7-(-1))/(-1-(-4))=(-7+1)/(-1+4)=-6/3=-2 so the slope is -2
