Martina is currently 8 years older than her cousin Joey. In 2 years she will be 3 times as old as Joey. Use this information to answer the following questions.

Answer:

I believe the answer is - 2/5 (negative two-fifths).

Step-by-step explanation:

First, you see if the answer is positive or negative:

Since the line is going up from right to left (the bottom arrow is on the right, top arrow is on the left), this means the slope will be negative.  A line that looks like this is always negative.

Now we calculate the slope:

The formula to find slope is rise/run (rise over run).  Since this is the formula, you need to find the rise first.  Start at the point on the 4th Quadrant.  Notice the dark blue line is going straight through the point.  Then notice the part where the line goes through in the top part of the arrow (the 2nd Quadrant).  Count the units up (rise) on the line in the 4th Quadrant until they vertically are congruent, or count 4 units up.  Then count to the left (run) until you meet the other dark blue line in the 2nd Quartile, or count 10 units to the left.  Now you make the fraction 4/10, but since this is a negative slope, the answer is     - 4/10.

But don't forget!  You always need to remember (if necessary) to simplify!!

- 4/10 = - 2/5

any number over itself is a whole

Does that answer it? I feel like I'm missing something

Answer:

Any

Answer:

9

Step-by-step explanation:

-Twice means muliply by 2

-The difference of a number and 7 means subtract a number/variable and 7.

-Is equal to 9 means =9

2(X - 7) = 9

An equation to model the number is: n - 7 x 2 = 2

To find the equation, break apart the question.

twice the difference of a number and 7 equals 2. - "Twice" means we are multiplying by 2, or x 2

twice the difference of a number and 7 equals 2. "The difference of a number and 7" means we are subtracting n - 7, and this is being multiplied by 2 so we have n - 7 x 2 so far.

twice the difference of a number and 7 equals 2. "Equals two" means the equation is equal to 2, or = 2, so our equation is n - 7 x 2 = 2.

Basketball all the way!

Step-by-step explanation:

You should pick volleyball, its quite fun

answer is 25

Step-by-step explanation:

for something like this you need to use the law of sins. First identify all the angles. There is a 90 degree angle and a 59 degree angle and those are clear. the missing angle is = 59 + 90 = 149

since a triangle has 180 degrees in total you say 180 - 149 = 31. the missing angle is 31 degrees. so we give the angles names. angle with 59 degrees will be angle A, 90 will be B and 31 will be C. So now we just give the sides names. let's replace that x with an a since it's across angle A. the side along angle B will be named b and the side along angle C will be named c. so you say:

Sin A/ a (sin A over a) = Sin B/b = Sin C/c

Sin A is what we are looking for so we say

59 degrees over/ x = sin 31 degrees/ 13 (we leave out the 90 degrees since we don't know the side and also we are not interested in it)

now we do cross multiplying.

say x ×sin 31 degrees = 13× sin 59

now divide these by sin 31

x = 13 × sin 59 ÷ 31 = 25

Answer:

y= 15

Step-by-step explanation:

Y= Kxz

y=6  x=1/2   z=6

15= K (1/2) (6)

15= K (3)

K= 5

SO

y= (5) (1/2) (6)

Y= 15

Answer:

k = 5

Step-by-step explanation:

Given y varies jointly as x and z then the equation relating them is

y = kxz ← k is the constant of variation

To find k use the condition y = 15 when x = [tex]\frac{1}{2}[/tex] and z = 6 , then

15 = k × [tex]\frac{1}{2}[/tex] × 6 = 3k ( divide both sides by 3 )

5 = k

Answer:

28. x(x+2)(x+5)

29. 2(2x+1)(x-2)

30. y(a+5)^2

Step-by-step explanation:

30. y(a+5)(a+5)

Answer:

-2(x+4)(x+2)

Step-by-step explanation:

thats the answerer

The equation is that of a parabola, meaning that the maximum (or sometimes minimum) is 1/2 the sum of the solutions found using the quadratic equation.

y = 0 for the 2 solutions to {-b +/- sqrt[b2 - 4ac]} / 2a, where a = -3, b = 152 and c = -1150 from the equation for y. Plug a, b and c into the quadratic formula to get x = 9.2571 and x = 41.4095 as the 2 solutions.

9.2571 + 41.4095 = 50.6666... and the midpoint is 25.3333...

When x = 25.3333..., y = 775.33333.....

To the nearest cent, x=25.33 results in a profit of 775.33.

When x=25.25, Y = 775.31

When x=25.4, Y = 775.32

These are both less than 775.33 when x = 25.33.

Answer:

I think the answer would be C 16 days.

I cant really see the bottom of the graph

Step-by-step explanation:

In 16 days Emily's lawn will achieve a height of 12 centimeters. option C is correct.

Given that,
Emily’s lawn grows at a constant rate. The height of her lawn, during a 10-day period. Based on the graph, after how many days will the lawn be 12 centimeters in height is to be determined.

The graph is a demonstration of curves that gives the relationship between the x and y-axis.

Here,
The slope of the graph = Δy/Δx = 1 / 2
Now,
Equation of the height of the lawn,
y - 4 = 1/2(x)
y = 1/2x + 4
Now, for y = 12
12 = 1/2x + 4
x/2 = 8
x = 8 * 2
x = 16

Thus, In 16 days Emily's lawn will achieve a height of 12 centimeters. Option C is correct.

Answer:diagonals of rectangle are equal in length while diagonals of a parallelogram can be different lengths

Step-by-step explanation:

What is true of a rectangle that is not true of a parallelogram is that; the diagonals of a rectangle are equal but the diagonals of a parallelogram are not equal.

We are dealing with rectangles and parallelogram here.

Now, both rectangle and parallelogram have 4 sides respectively with 2 of the sides being equal.

Now, for a rectangle, the diagonals are always equal because all the internal angles are equal.

However, for a parallelogram, all the internal angles are not equal and as such the diagonals are also not equal.

In conclusion, what is true of a rectangle that is not true of a parallelogram is that the diagonals of a rectangle are equal but the diagonals of a parallelogram are not equal.

A simulation for the given scenario using a standard deck of playing cards would be,

Draw a card from a deck of standard playing cards three times, with face cards representing those who prefer a comedy and the other cards representing those who prefer an action movie.

According to the question,

A cable channel survey showed

on Saturday night subscribers preferred watching a comedy = 50%

subscribers preferred watching a Action = 50%

We need to design the scenario using a standard deck of playing cards

In a playing cards sets,

50% of playing cards set =  subscribers preferred watching a comedy

& rest 50% of playing cards set = subscribers preferred watching Action

But we want to estimate the probability that exactly two of three randomly picked subscribers prefer watching action movie on a Saturday night,

Here, the face cards are 12 in number out of 52.

So, there are 40 number cards.

So, the probability of a number card occurring is more.

So, as it is to be estimated that 2 out of 3 people prefer to watch action movie

This means, Draw a card from a deck of standard playing cards three times, with face cards representing those who prefer a comedy and the other cards representing those who prefer an action movie.

Hence a simulation for the given scenario using a standard deck of playing cards would be,

Draw a card from a deck of standard playing cards three times, with face cards representing those who prefer a comedy and the other cards representing those who prefer an action movie.

The probability of rolling a 3 the first time is 1/6.

The probability of rolling an even number is 1/2.

Answer:

x=2

Step-by-step explanation:

Answer:

Step-by-step explanation:

c(f) = [tex]\frac{5}{9}(f-32)[/tex]

[tex]-21 = \frac{5}{9}(f-32)[/tex]

Multiply both sides by 9

-21*9 = 5(f - 32)

-189 = 5*f - 5*32

-189 = 5f - 160

Add 160 to both sides

-189 + 160 = 5f

-29  = 5f

Divide both sides by 5

-29/5 = f

f = -5.8

f = -6 °C
