HELP what is 0.8120^-2=y16

Answer:

d = 8

Step-by-step explanation:

Given

8 + 4d = 5d ( subtract 4d from both sides )

8 = d

Answer:

d=8

Step-by-step explanation:

8+4d=5d

1. subtract 8 from both sides > 8+4d-8=5d-8

2. simplify > 4d=5d-8

3. subtract 5d from both sides > 4d-5d=5d-8-5d

4. simplify again > -d = -8

5. divide both sides by -1 > -d/-1 = -8/-1

6. simplify again > d=8

Answer:

1/10 does terminate. 1/10 in decimal form is .1

Step-by-step explanation:

Answer:

A: 3

B: 1

C: 5

D: 6

E: 4

F: 2

Step-by-step explanation:

A: The arrows should be a giveaway; you're distributing the 3 into the parentheses.

B: Step shows adding 12, and only one of those properties has anything to do with addition, the addition property of equality. The property basically says that if we already know that 6x - 12 is equal to 18, then if we add any number to both sides (given that the same number is added to both sides), the two sides will still be equal. The other properties, for subtraction, multiplication, and division work the same way except with a different operation.

C: Step shows multiplying both sides by 2, so it's the multiplication property of equality.

D: Step shows subtracting both sides by -6x, so it's the subtraction property of equality.

E: Step shows dividing both sides by 6, so it's the division property of equality.

F: Step shows combining two terms that both have x as a variable, so it's combine like terms.

Don’t make sense sorry

Step-by-step explanation:

Answer:

y = -5x + 4

Step-by-step explanation:

In the equation y = mx + b , m stands for slope and b stands for the y intercept. In the coordinates (-1,4) the y value is 4 meaning that it's your y-intercept. The slope is already given to you so just add the X.

Answer:

y = -5x - 1

Step-by-step explanation:

Since you have the slope and a given point you can use the point-slope formula to solve for the y-intercept formula.

Point slope formula = y - y = m(x - x)

m = -5    (-1, 4)

y - 4 = -5(x +1)

y - 4 = -5x - 5

y = -5x - 1

Answer:

Answer:

0.08 mile or 422.4 feet

Step-by-step explanation:

Distance=2 miles

number of volunteers=25

Length for each volunteers

[tex]2\frac{2}{25} miles=0.08 mile\\[/tex]

= 422.4 feet (as mile =  5280 feet)

0.08 mile or 422.4 feet

Answer:

all i know is species A is faster, but i dont really feel like seeing witch one goes how much slower or faster

Step-by-step explanation:

ok so if you use the unit speed, you should get a higher one for species A.

Answer:

the bigger number 6 is 36

Answer:

2.6667 hours

Step-by-step explanation:

Given that:

Distance between car and bus = 280 miles apart

What le moving towards each other ;

Speed of car = 55 mph

Speed of bus = 50 mph

Time it will take them to meet;

Time = distance / speed

Hence :

Total distance to be covered = 280 miles

Total speed = (55mph + 50 mph) = 105 mph

Hence ,

Time = 280 miles / 105 mph

Time = 2.667 hours

2 hours, (0.667 * 60 = 40.02

2 hours, 40 minutes

Answer:

2.6667

Answer:

You would need 250 bottles to collect $10.

Step-by-step explanation:

10 bottles / 25 cents = 0.4 cents per bottle

10 bottles / 0.4 cents per bottles = 25 bottles

25 bottles * 10 bottles = 250 bottles

Hope this helps:)

Answer:

25 cents x 40 bottles =10.00

Step-by-step explanation:

25 cents = 10 bottles

1 dollar = 40 bottles

40 bottles = 20$

Answer:

Annie will have $87.75 more than Ellie

Step-by-step explanation:

Annie :

Answer:

(-10,-3)

Step-by-step explanation:

okay so first, we can plot the points (-3,2) and (4,7) on a graph. after graphing these points, look at the difference between the y-values. this is 5 because 7-2 is 5. now, look at the x-values. this is 7 because 4-(-3) is 7. so this means we have to go on the other side of the midpoint (-3,2) and go 5 lines down from that point. this brings us at (-3,-3). now, we have to go 7 lines to the left. this is (-10,-3). this is the other endpoint.

you can also graph this on desmos to double-check.

hope this helps:)

Answer:

These lines are linear lines.

Step-by-step explanation:

Linear lines are straight lines. We can determine if a line is linear in one of a few ways, three being:

By looking at the lines. If they are straight, then they are linear.

By looking at a graph. If there is a constant rate of change within the graph (between the points), then the line is linear. A constant rate of change is when something is changing at a constant, or not-changing number. For example, if the rate of change is 3 (+3 or -3), and never any other number, then the line is linear.

By solving the equation. For a line to be linear, it has to be able to fit in the slope-intercept form (y = mx + b) (without any exponents). If the equation does not work for the line, then the line is likely non-linear. A linear line may also have two expressions that are equal to each other. It's a little hard to see the entire second equation in the picture, but it appears to be 4x - 7. Meanwhile, the first equation is -2x + 5. Clearly, both lines are linear as they both fit in/follow the slope-intercept form. The m's are: -2 and 4, and the b's  are 5 and -7.

Answer:

5/6

Step-by-step explanation:

1/2 = 3/6 because 1/2 x 3 = 3/6. 2/3 = 4/6 because 2/3 x 2 = 4/6. 3/6 plus 4/6 equals 7/6 or 1 and 1/6. 2 - 1 1/6 = 5/6.

Answer:

6 weeks

Step-by-step explanation:

If you look at the information it gives you, you can see it says 12 quizzes in 3 weeks and she needs 24 quizzes. So every 3 weeks she does 12 quizzes, and if you add 12 and 12 you get 6 weeks.

Answer:

put a dot on the following points ( -1, -3) (0, -2) (1, -1) and (2, 0)

Step-by-step explanation:

Answer:   [tex]\sqrt{ (-3-a)^2 + (7-b)^2 }[/tex]

Explanation:

We plug the given coordinates into the distance formula

[tex]d = \sqrt{ (x_1-x_2)^2 + (y_1-y_2)^2 }\\\\[/tex]

There isn't much we can do from there since we don't know the values of 'a' or 'b'. You could expand out each binomial, but it's more simplified being factored like that.

The final two steps used to convert units between different systems of measurement are given by;

Option C; 4. Multiply the original measure by the conversion factors.

5. Check for reasonableness

To answer this question, let us take an example of converting from inches to centimeters.

Let us convert 10 inches to centimeters.

First step is to identify the measure to be converted which in this case it is inches that is the measure.

Second step is to write the conversion factors which is;

1 inch = 2.54 cm

Third step is to cancel the units; In this case the units to be canceled will be inches.

Fourth step is to multiply the original measurement by the conversion factor to give; 10 × 2.54 cm = 25.4 cm

Fifth step is to check for reasonableness by trying to check if using another number will give a reasonable answer.
