Need help please! (Will mark as Brainliest)

Answer:

1. The negative sign on an exponent means the reciprocal. A negative exponent tells how many times to divide a base number.

2. A positive tells how many times to multiply a base number.

could you also give me a brainliest if I am correct.

thanks!

Answer:

its changing by 6 if you look the get subtracted or added by six to mae those numbers

Step-by-step explanation:

31 + 6= 37

37 + 6= 43

43 + 6= 49

49 + 6= 55

y + 82 = 10x is the answer.

Answer:

y+72 = 10(x-1)

Step-by-step explanation:

I don't really know why this would be useful for solving a problem; please tell me in the comments of my answer.

Anyway, I would pick a random point that would satisfy this equation. One example would be (1, -72)

Now just plug those 2 numbers into the equation:

y+72 = 10(x-1)

Here you go :)

Step-by-step explanation:

0.0125 gallons of 35% solution is needed.

Given that,

Eli wants to combine 0.5 gallons of a 10% acid solution with a 35% solution to make a 15% acetic acid solution.

Eli decides to let v represent the volume of the 35% solution.

We have to find,

How many gallons of 35% solution is needed?

According to the question,

Eli decides to let v represent the volume of the 35% solution.

And 0.5 gallons of 10% acid solution,

the volume of the 15% acid solution is (v +0.5).

Therefore,

0.5 gallons of a 10% acid solution with a 35% solution to make a 15% acetic acid solution.

[tex]\rm = 0.5 \times \dfrac{10}{100} + v \times \dfrac{35}{100} = (v+0.5) \times \dfrac{15}{100}\\\\= 0.5 \times 0.01 + v \times 0.35 = (v+0.5) \times 0.15\\\\= 0.05 + 0.35v = 0.15v + 0.075\\\\= 0.35v - 0.15v = 0.075 -0.05\\\\= 0.20v = 0.025\\\\v = \dfrac{0.025}{0.20}\\\\v = 0.0125[/tex]

Hence, 0.0125 gallons of 35% solution is needed.

Step-by-step explanation:

Answer:

1. f > 40 miles/gallon

2. t < 35 degrees

Answer:

For part one the vehicle cannot have less than 40mpg so the equality would be

[tex]f\geq 40mpg[/tex] because the mpg must be greater than or equal to 40mpg.

For part two the temp must be LESS than 35 not including 35.

so we would show that with [tex]t<35F[/tex]

The value of x is 12.

Angles that are vertically opposed to one another at a certain vertex are formed by two straight lines intersecting. Angles that are vertically opposed to one another are equal.

The two angle are (4x - 25)° and (2x - 1)°,

Since, both the angles are vertically opposite angle,

Therefore, by the vertically opposite angle property,

Both the angles will be equal.

4x - 25 = 2x - 1

2x = 24

x = 12

The value of x is 12.

Thank You!!

Answer:

The quantity is 12

Step-by-step explanation:

Here, we want to find the solution to the equation.

Let the quantity we are looking for be x;

According to the question;

The quantity plus a quarter of the quantity = 15

x + 1/4(x) = 15

x + x/4 = 15

Multiply through by 4

4x + (x/4)*4 = 15 * 4

4x + x = 60

5x = 60

x = 60/5

x = 12

Answer:

so for one, just put a line horizontal to line 1

part two I'm assuming you do the same as p since it's not asking you to make it perpendicular to line 1.

part three, create going through line 1 (vertical)

part four constructs the same triangle, but just move the points a little so that way it's not overlapping.

Step-by-step explanation:

parallel means not touching

perpendicular means crossing each other paths.

Answer:

[tex]y=13\text{ miles per gallon}[/tex]

Step-by-step explanation:

We have the two points: (0, 11) and (3, 50).

And we want to find the rate of change in y relative to x, where x is the gallons and y is the miles.

In simple terms, we want to find the slope between the two points.

So, let's use the slope formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Let (0, 11) be (x₁, y₁) and let (3, 50) be (x₂, y₂). Substitute. Let's also put "miles" in the numerator with the Ys and "gallons" in the denominator with the Xs. This yields:

[tex]y=\frac{50-11\text{ miles}}{3-0\text{ gallons}}[/tex]

Subtract and reduce:

[tex]y=39\text{ miles}/3\text{ gallons}=13\text{ miles per gallon}[/tex]

And we're done!
