Answer:

y = 3x + 1

Step-by-step explanation:

The general form of the slope intercept form is y = mx + b where m is the slope and b is the y-intercept.  

In perpendicular lines, we find the slope of the second equation (m2) using the formula:

[tex]m_{2}=-\frac{1}{m_{1} }[/tex]

Since -1/3 is m1 we have:

[tex]m_{2}=-\frac{1}{-(\frac{1}{3}) } \\ m_{2}=3[/tex]

Now that we've found the slope of the second line, we simply need to find b or its y-intercept by plugging in (-2, -5) and our slope:

[tex]-5=3(-2)+b\\-5=-6+b\\1=b[/tex]

Thus, the equation of the second line is y = 3x + 1

Answer:

Step-by-step explanation:

x=0

y=3(1/4)^x-1

y=3(1/4)^0-1

y=3(1)-1

y=2

y intercept is at (0,2)

If someone purchased 7 adult tickets and 3 kids tickets, they would get 10 total tickets.

If someone purchased a adult tickets and k kids tickets, they would get a+k total tickets.

Slope intercept form has the general form of y = mx + b, where m is the slope and b is the y-intercept.

You are given the y-intercept with the point (0, -10). Thus, the y-intercept is -10.

You are also given the slope of 1.

Next, just plug your numbers in!

y = 1x - 10

y = x - 10

Answer: 20.65

Step-by-step explanation:

2.95 is the unit rate x 7 equals 20.65

Answer:

Step-by-step explanation:

We set up a proportion to find X, which in this case is the cost of seven packages.

Proportion: 5.90:2=x:7

Unit cost: 5.90/2=2.95

But we want to find the cost of seven cookies.

So, we multiply the unit cost by 7.

2.95*7= 20.65

Thus, seven packages of cookies costs $20.65.

You planted the tomato seeds on the 10th of May

The complete question is added at the end of this solution

From the question, we have the following parameters that can be used in our computation:

Number of days to ripe = 80 days

Date the tomato seed is eaten = July 29

The above parameters can be represented using the following subtraction equation:

The date you planted the seeds = Date the tomato seed is eaten - Number of days to ripe

Substitute the known values in the above equation, so, we have the following representation

The date you planted the seeds = July 29 - 80 days

Evaluate the difference

So, we have the following representation

The date you planted the seeds = May 10

Hence, the date you planted the seeds is May 10

1. The problem involves finding the length of a slide about a ladder. The slide and the ladder form a right triangle, with the ground and the slide as the hypotenuse.

2. The top of the ladder is 10 feet above the ground, and the bottom of the ladder is 12 feet from the bottom of the slide.

3. In order to solve this problem, a diagram can be used to represent the scenario.

4. Label the bottom of the slide as point A, the bottom of the ladder as point B, and the top of the ladder as point C.

5. Draw a straight line from point A to point B and label it 12 feet.

6. Draw a straight line from point B to point C and label it 10 feet.

7. Draw a straight line from point A to point C, which is the hypotenuse of the triangle.

8. Use the Pythagorean Theorem to find the length of the hypotenuse.

9. The Pythagorean Theorem states that a2 + b2 = c2, where a and b are the sides of the triangle and c is the hypotenuse.

10. In this problem, a is 12 feet, and b is 10 feet. Plugging these values into the equation, we get 122 + 102 = c2. Solving for c, we get that the length of the slide is 14.04 feet to the nearest tenth of a foot.

Step-by-step explanation:

The number of student that took neither chemistry nor biology is 17.

A study of 50 high school students showed that exactly 25 of them took biology, exactly 20 of them took chemistry, and exactly 12 of them took both subjects.

The number of student that took neither biology nor chemistry can be calculated as follows;

Hence,

U = 50

n(C) = 20

n(B) = 25

n(B n C) = 12

n(B n C)' = ?

Therefore,

U = n(C) + n(B) - n(B n C)  + n(B n C)'

Therefore,

50 = 20 + 25  - 12 + x

50 - 45 + 12 = x

x = 5 + 12

x = 17

Therefore, 17 student took neither chemistry nor biology.

Step-by-step explanation:

Just multiply 108 by 16.

Answer:

384 ounces

Step-by-step explanation:

If it takes 4 1/2 pounds of grapes to make 1 pound of Rasins, then we need to figure out how many pounds of Rasins we can make with 108 pounds of grapes.

(Or you can do 108 divided by 4 1/2)

4 1/2 x 10 = 45

4 1/2 x 4 = 18

45 + 45 + 18 = 108

10 + 10 + 4 = 24

(Looking at the work you did above, we can take 54, and multiply that by 2 to get 108, therefore, we can just multiply 12 by two to get 24)

Now we need to convert the pounds to ounces.

If one pound is equal to 16 ounces, then we can use the equation,

24 x 16 = 384

108 pounds of grapes yields 384 ounces.

The equation of the line can be written as y = -x - (7/12).

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is y-intercept.

Given that the line passes through  (5/12, −1) and (−3/4, 1/6). Therefore, the slope of the line can be written as,

Slope of the line = [(1/6) - (-1)] / [(-3/4) - (5/12)]

                            =  [(1/6) + 1] / [(-3/4) - (5/12)]

                            = (7/6) / [(-9-5)/12]

                            = (7/6) / (-14/12)

                            = -1

Now, the equation can be rewritten with slope and a point as,

y = mx + c

(1/6) = -1(-3/4) + C

(1/6) = (3/4) + C

C = (1/6) - (3/4)

C = (2/12) - (9/12)

C = (-7/12)

Therefore, the equation of the line can be written as,

y = mx + c

y = (-1)x + (-7/12)

y = -x - (7/12)

Hence, the equation of the line can be written as y = -x - (7/12).

The polynomial expression that represents the perimeter is (3x^3 +3x -148)ft and the value is 182ft

Polynomials are algebraic expressions that consist of variables and coefficients. Variables are also sometimes called indeterminates. We can perform arithmetic operations such as addition, subtraction, multiplication, and also positive integer exponents for polynomial expressions but not division by variable.

Perimeter of the triangle is the sum of the sides of the triangle which is = 2x^2 -120 + x^2 -5x +8x -28

Perimeter = (3x^2 +3x -148)ft

when x = 10

Perimeter = 3(10)^2 +3(10) -148 = 182ft

Probability of landing on red 0.9%, when Yolanda spun the dial 1000 times.

What is probability?

The probability of an event can be calculated using the probability formula by simply dividing the favorable number of possibilities by the total number of outcomes. The likelihood of an event occurring can be anywhere between 0 and 1, as the favorable number of outcomes can never exceed the total number of outcomes.

A spinner with 10 equally sized slices has 4 yellow slices, 4 red slices, and 2 blue slices.

Yolanda spun the dial 1000 times.

P( getting red)  = 19/1000

From the chart, there are 19  red out of 1000

Experimental probability of landing on red

= Number of red outcomes / Total number of spins

The value of angle RPQ in the circle is 115 degrees.

The intersecting chords theorem, also known as the chord theorem, is an elementary geometry statement that describes a relationship between the four line segments formed by two intersecting chords within a circle.

If two chords intersect inside a circle, then the measure of the angle formed is one half the sum of the measure of the arcs intercepted by the angle and its vertical angle.

Therefore,

∠RPQ = 1  / 2 (arc angle RQ + arc angle SA)

arc angle RQ = 175 degrees

arc angle SA = 55 degrees

Hence,

∠RPQ  = 1 / 2 (175 + 55)

∠RPQ  = 1 / 2 (230)

∠RPQ  = 115 degrees.

The angle is 115°.

Step-by-step explanation:

Mackenzie has 3200 more red marbles than yellow,

(y + 3200 = r)

And she also has 3840 more blue marbles than the yellow marbles,

(y + 3840 = b)

Then let's assume that Mackenzie has 1 yellow marble.

1 + 3200 = 3201 red marbles

1 +3840 = 3841 blue marbles

If she gives away 1490 blue marbles away, then she is left with 2351 blue marbles.

(3841 - 1490 = 2351)

Now she's left with 2351 blue marbles, and 3201 red marbles.

r - b =?

3201 - 2351 = 850

Mackenzie has 850 more red marbles than blue marbles.
