slope is -1

y= -1x+3

Step-by-step explanation:

rise over run

slope going down to the right is negative

Answer:

The slope is -1

Answer:

y = 4

Step-by-step explanation:

When given a point and a slope, we use slope-intercept formula:

y - y1 = m (x - x1)

m = slope  point: (-4,4)

y - y1 = m (x - x1)

y - 4 = 0 (x - 1)

y - 4 = 0x + 0

 + 4          + 4

y = 4

The answer can't be written in slope-intercept form, as the 0"s cancel out.

The formula t = 5n, where "t" denotes the duration in minutes and "n" is the number of songs played, describes the relationship between the number of songs played and the duration. By applying this calculation to the 7:30 to 11:30 pm time period provided, we can determine that the D.J. played a total of 48 songs.

a. To generate a formula showing the relationship between songs played and time taken, we can use the following approach:

Let "n" represent the number of songs played and "t" represent the time taken in minutes.

Given that a fresh song is played every 5 minutes, we can establish the following equation:

t = 5n

This formula shows that the time taken is directly proportional to the number of songs played. For every song played, it takes 5 minutes.

b. Given that the last song stopped playing at exactly 11:30 pm, we need to determine the total time taken from 7:30 pm to 11:30 pm.

7:30 pm to 11:30 pm is a total of 4 hours or 240 minutes.

Using the formula derived in part (a), we can substitute the total time taken into the equation:

t = 5n

240 = 5n

Simplifying the equation, we find:

n = 240 / 5

n = 48

Therefore, the D.J played a total of 48 songs.

Step-by-step explanation:

The difference in sale prices between the two stores is $4.5.

A discount is the reduction of either the monetary amount or a percentage of the normal selling price of a product or service.

Given that, a $30 sweater is on sale for 20% off at Kohls.

Here, sales price = 30-20% of 30

= 30-20/100 ×30

= 30- 0.2×30

= 30-6

= $24

The same $30 sweater is on sale at Macy's for $5 off the price.

Here, sales price = 30-5% of 30

= 30-5/100 ×30

= 30- 0.05×30

= 30-1.5

= $28.5

So, difference in price = 28.5-24

= $4.5

Therefore, the difference in sale prices between the two stores is $4.5.

Answer:

891 ft³

Step-by-step explanation:

First I'll find the volume of the rectangular prism. (l * w * h)

12 * 9 * 7.5

Multiply 12 by 9 to get 108.

108 * 7.5

Now, multiply 108 by 7.5 to get 810. (756 + 54 = 810)

810

Now for the triangular prism. (1/2(l * w * h))

1/2(12 * 9 * 1.5) (I figured the height was 1.5 since the height of the rectangular prism was 7.5; the entire figure's height was 9)

Multiply 12 by 9 to get 108.

1/2(108 * 1.5)

Multiply 108 by 1.5 to get 162. (108 + 54 = 162)

1/2(162)

Multiply 162 by 1/2 to get 81. (162/2)

81

Now add that to 810 to get 891.

810 + 81

891 ft³

The volume of the garage is 891 ft³.

Answer:

The value of x = 0    

Step-by-step explanation:

Given

To determine

The value of x = ?

If we closely observe the value of the y-coordinate of the image B'(x, 20), we can see that the y-coordinate of the image B' is 4 times the y-coordinate of the original point (0, 5).

i.e. y → 5×4 =20

It means the coordinates of the image B'(x, 20) can be determined by dilating the original point (0, 5) by a scale factor of 4.

Thus, the x-coordinate of B'(x, 20) can also be obtained by multiplying the x-coordinate of B(0, 5) by 4.

i.e. x → 4×0 = 0

Thus, the rule of dilation is:

P(x, y) = P'(4x, 4y)

Hence,

B(0, 5) → B'(4(0), 4(5)) → B'(0, 20)

Thus,

The value of x = 0           ∵ 0×4 = 0

Louise has walked B. 9 miles

Since Louise is walking 12 miles to raise funds for a local cause. and If she has completed 3/4 of the distance, the number of miles she has walked, t = total distance × fraction of total distance.

Since total distance = 12 miles, and fraction of total distance = 3/4.

The number of miles she has walked, t = total distance × fraction of total distance.

Substituting the values of the variables into the equation, we have

t = 12 × 3/4

t = 3 × 3

t = 9 miles.

So, Louise has walked B. 9 miles

Answer:

the solution for x is x = −3.

Step-by-step explanation:

To solve for x, we need to isolate it on one side of the equation. We can do this by adding 15 to both sides:

−15 + x + 15 = −18 + 15

Simplifying:

x = −3

Therefore, the solution for x is x = −3.

In the image line segment SE is the tangent. The secant line making an angle with tangent line SE is NS. So the angle is ∠GSE. So option B is the correct answer.

Tangent is a line which intersect with only a single point on the curve. The point where the line meets is the point of tangency. Tangent line is always perpendicular to the radius drawn to the point of tangency. Here the tangent line is SE, point of tangency is S.

Secant lines are the lines which passes through two points of a curve. A chord drawn to the circle is a secant line. Here there are two secant lines NS and NA. Here only NS makes an angle with the tangent line.

So the angle made by a tangent and secant line is ∠GSE.

x = 52

Step-by-step explanation:

The triangle is isosceles. The markings tell us that.

The 76 is not opposite either one of the equal sides. Let the angle values opposite the equal sides be x

x + x + 76 = 180                      All triangles = 180

2x + 76 = 180                         Subtract 76 from both sides.

2x = 180 - 76

2x = 104                                 Divide both sides by 2

x = 104/2

The correct option is; 4: this contradicts the Mean Value Theorem since there exists a c on (1, 7) such that f '(c) = f(7) − f(1) (7 − 1) , but f is not continuous at x = 3.

The function being used is;

f(x) = (x - 3)⁻²

If we separate this function according to x, we obtain;

f'(x) = -2/(x - 3)³

Finding all c values f(7) − f(1) = f '(c)(7 − 1).is our goal.

This suggests that;

0.06 - 0.25 = -2/(c - 3)³ x 6

-0.19 =  -12/(c - 3)³

(c - 3)³ = 63.157

c = 6.98

If the Mean Value Theorem holds for this function, then f must be continuous on [1,7] and differentiable on (1,7).

But when x = 3, f is not continuous, hence the Mean Value Theorem's prediction is false.

The new price of the purchase after the 13% discount can also be expressed as 0.87x.

The new price of the purchase after the 13% discount is expressed as x - 0.13x.

x - 0.13x = x(1 - 0.13) (1 - 0.13).

We can simplify the expression in parentheses as follows:

1 - 0.13 = 0.87.
