Answer:

1/2

Step-by-step explanation:

(-4--2)/(3-7)=-2/-4=1/2

Answer:

b. 1/2

Step-by-step explanation:

Points: (7, -2), (3, -4)

slope = (y2 - y1)/(x2 - x1)

slope = (-4 - (-2))/(3 - 7) = (-4 + 2)/(-4) = -2/(-4) = 1/2

Answer: -3.5 or -3 1/2

Step-by-step explanation: Put in the numbers -3 and 5 for the variables and simplify, (-2)-3 -2(5) -1/6(-3), to get 6 - 10 + 1/2(or 0.5), then add and subtract, 6-10= -4 + 0.5 = -3.5 or -3 1/2.

Answer:

The answer is -2, -8.

Step-by-step explanation:

Since the three coordinates of the vertices are A(-5,–8), B(-5,0), and C(-2,0), the fourth vertices of the rectangle will be D(-2, -8)

It is described as a type of two-dimensional geometry where the angle between neighboring sides is 90 degrees. A quadrilateral of that kind is it. in two-dimensional planning geometry, the space occupied by the rectangle.

The following formula may be used to determine the area of a rectangle:

​Rectangle area = length x width

It is given that the three coordinates of the rectangle are A(-5,–8), B(-5,0), and C(-2,0).

We have to find the fourth vertices coordinates of the rectangle will be D(-2, -8)

Let the fourth vertices coordinates of the rectangle will be (x,y).

Since the parallel side of the rectangle is the same. Plotting the graph we will obtain the coordinates of the D.

Thus, the fourth vertices of the rectangle will be D(-2, -8)

true flip a coin it's  fifty fifty

Answer:

False

Step-by-step explanation:

Each toss is an independent event, so the probability of three tosses of heads in a row is the product of the three probabilities..

Each probability of heads is

p(heads) = 1/2

p(heads, heads, heads) = p(heads) * p(heads) * p(heads) = 1/2 * 1/2 * 1/2 = 1/8

Answer: the answer is 3.2 miles

Step-by-step explanation:

The distance the fisherman rowed is 3.2 miles if the fisherman can row upstream at 1 mph and downstream at 4 mph.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

A fisherman can row upstream at 1 mph and downstream at 4 mph.

He started rowing upstream until he got tired and then rowed downstream to his starting point.

Let the time of row upstream is x hours

Let the time of row downstream be y hours

From the question:

x + y = 2

x = 2 - y

x = 4y

Solving the above two linear equations by substitution method:

2 - y = 4y

5y = 2

y = 2/5

y = 0.4 hours

Distance = speed×time

Distance = 4×0.4 = 1.6 miles

= 1.6×2 = 3.2 miles

Thus, the distance the fisherman rowed is 3.2 miles if the fisherman can row upstream at 1 mph and downstream at 4 mph.

Answer:

12 less than or equal to 2

Step-by-step explanation:

The inequality for the given statement is $12 ≤ $2(n).

The equations with inequalities are those who have unequal sides on both sides. Unlike the equation, we compare the two values when we work with inequality. The equal sign is substituted between by being less than (or less than or equal to), larger than (or greater or equal to), or not equal to sign.

As per provided data from the question,

Total money to spent on the ride tickets = $12

Price of each ticket for a ride =$2

So, the inequality will be : $12 ≤ $2(n), here n is the number of rides.

Answer:

$6.00-($2.00+$4.50)

in other terms, 6 - (2 + 4.5)

Step-by-step explanation:

So first, we know that they spent 6 in total. To figure out how much they spent, we need to figure out how much they had all together.

To get how much all together, we have to add. 2 + 4.5

Now that we now how to get the total amount, out them in parentheses and add the 6 infront.

Since we need to find the remaining amount, were subtracting 6 from the total, hence the parentheses.

All this leads to the expression: 6 - (2 + 4.5)

Answer:

y = ± [tex]\sqrt{\frac{a-x}{2b} }[/tex]

Step-by-step explanation:

Given

x = a - 2by² ( subtract a from both sides )

x - a = - 2by² ( multiply through by - 1 to clear the leading negative )

a - x = 2by² ( divide both sides by 2b )

[tex]\frac{a-x}{2b}[/tex] = y² ( take the square root of both sides )

y = ± [tex]\sqrt{\frac{a-x}{2b} }[/tex]

Making y the subject of the formula, [tex]x = a - 2by^2[/tex] , the answer would be:

[tex]\mathbf{y = \sqrt{\frac{x - a}{-2b}} }[/tex]

Given the formula: [tex]x = a - 2by^2[/tex],

Required:

Making y the subject of the formula

This is done as shown below:

[tex]x = a - 2by^2[/tex]

[tex]x - a = - 2by^2[/tex]

[tex]\frac{x - a}{-2b} = y^2[/tex]

[tex]\sqrt{\frac{x - a}{-2b}} = y\\\\\\\mathbf{y = \sqrt{\frac{x - a}{-2b}} }[/tex]

Therefore, making y the subject of the formula, [tex]x = a - 2by^2[/tex] , the answer would be:  [tex]\mathbf{y = \sqrt{\frac{x - a}{-2b}} }[/tex]

-2 = x + 4

Step 4: Subtract 4 on both sides

-6 = x

Step 5: Rewrite

x = -6

Answer:

x = -6

Answer:

Step-by-step explanation:

The direct proportion equation is y = kx which reads, "y is directly proportional to x". k is the constant of proportionality. In our case, we read this is as, "the number of calories is directly proportional to the number of apples eaten." Our equation would look like c = ka. We first are given that a = 4 and  = 380. We will use that to solve for k:

380 = k4 so

k = 95. Now that know the value of k, we will use that along with the number of calories (1045) to find the number of apples, a:

1045 = 95a so

a = 11

This means that it will be 11 apples that contain 1045 calories.
