Yolanda's age is 5 years less than twice Marco's age. If Yolanda is 15 years old, how old is Marcus? Choose the answer below that is a viable solution to this problem.

Answer:

  (-∞, -5/2) ∪ (1, ∞)

Step-by-step explanation:

"Increasing" means the graph goes up to the right. It is increasing from the left up to the local maximum--the peak at left.

It is increasing again from the local minimum on the right to the right side of the graph.

The two sections where the graph is increasing are ...

  (-∞, -5/2) ∪ (1, ∞)

__

The graph is decreasing between the maximum on the left and the minimum on the right.

Answer:

36

Step-by-step explanation:

F1 = 1

F2 = 1 + 2

F3 = 1 + 2 + 3

--> The n(th) figure has the number of oranges = the sum of the first n natural numbers, which has the general form:

F(n) = 1 + 2 + 3 + ... + n = n(n+1) / 2

So, 8th figure has:

F(8) = 8.(8+1) / 2 = 8 . 9 / 2 = 36

Answer:

Step-by-step explanation:

X X X X . X X X

   ^ this is the hundreds place

X X X X . X X X

                   ^ this is the hundredths place

a) 300 Because the place behind it is less than 5.

b) 1300 The place in the tens is 5 or greater.

c) 10,000 The place in the tens is 5 or greater which causes the 9 in the hundreds to go up which also causes the 9 in the thousands to go up as well.

d) 1,100

e) 700

Answer: First we will substitute the numbers in place of the variables in the equation, and then we will use order of operations to solve.

7x + 6y would be equal to:

7(2) + 6(10)

Now we will perform the multiplication:

7 * 2 = 14

6 * 10 = 60

The equation now looks like:

14 + 60

This is equal to 74. Your answer is therefore 74.

Hi there! Hopefully this helps!

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

First we need to evaluate the variables into the expression.

7x + 6y = 7(2) + 6(10).

6 x 10 = 60

7 x 2 = 14.

60 + 14 = 74

3x^3 + 12x^2 - 45x

Step-by-step explanation:

Multiply 3x with x^2 then 4x and then -15 in order

3x × x^2 = 3x^3

3x × 4x = 12x^2

3x × (-15) = -45x now add the expressions

3x^3 + 12x^2 - 45x

Answer:

-3

Step-by-step explanation:

-7x=-2x+15

Answer:

$271.00. Remember to put it in the right format

Step-by-step explanation:

So since its 35 dollars per day, we can first do 35*4 to get 140. So just for having the car, it costs 125 dollars.

Now to find the amount of money for the miles, we can do 730*0.20=146

Now we add those two amounts so we do 125+146=271.

So $271.00

Answer:

0.55x+4<=25

Step-by-step explanation:

It would be 0.55x because x is the number of bananas and 0.55 is the cost and the 4 represents the $4 she spent for a papaya. The 25 is the amount of money she has so it says less than or equal to because she only has so much money.

Answer:

y = x² - 2

Step-by-step explanation:

Quadratic Parent Function: y = a(bx + h)² + k

k = vertical movement up/down

Since we are only dealing with a vertical shift down, we are only modifying variable k

k = -2

y = x²

y = x² - 2

Answer:

Yes, it is.

Step-by-step explanation:

A function is a relation between two sets of elements, where each valid input can be mapped to exactly one output.

Indeed, the relation in this question is between two sets of elements. Each of these pairs includes exactly two elements: the input and the output.

On the other hand, does this relation maps each valid input to exactly one output? Arrange these pairs by the input in increasing order:

Indeed, the input [tex]-3[/tex] appeared twice in the list. However, in both occurrence, this input mapped to the same output, [tex]6[/tex]. This relation is still a function.

Answer:

[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{25 {x}^{4} - 4}}}}}[/tex]

Step-by-step explanation:

[tex] \sf{(5 {x}^{2} - 2)(5 {x}^{2} + 2)}[/tex]

Use the distributive property to multiply each term of the first binomial by each term of the second binomial.

[tex] \dashrightarrow{ \sf{5 {x}^{2} (5 {x}^{2} + 2) - 2(5 {x}^{2} + 2)}}[/tex]

[tex] \dashrightarrow{ \sf{25 {x}^{4} + 10 {x}^{2} - 10 {x}^{2} - 4}}[/tex]

Since two opposites add up to zero , remove them from the expression

[tex] \dashrightarrow{ \sf{25 {x}^{4} - 4}}[/tex]

Answer:

8- b=79

9- b=23

10- b=67

8.)

[tex]37 = n - 42[/tex]

Add 42 to both sides of the equal sign to isolate the variable (n).

[tex]79 = n[/tex]

9.)

[tex]b + 62 = 85[/tex]

Subtract 62 from both sides of the equal sign to isolate the variable (b).

[tex]b = 23[/tex]

10.)

[tex]92 = 25 + l[/tex]

Subtract 25 from both sides of the equal sign to isolate the variable (l).

Answer:

Johnny will be able to reach the safe zone before the gate is closed.

Step-by-step explanation:

Given that:

Distance of Little Johnny from safe zone = 4000 feet

Time = 3 minutes

Speed = 22 mph

To find:

Will Johnny be able to reach the safe zone ?

Solution:

Johnny can only be safe if he can travel 4000 feet in 3 minutes with the given speed.

Let us try to find out, the distance that he can travel in 3 minutes at speed of 22 mph.

Let us have a look at the formula of distance traveled:

[tex]Distance = Speed \times Time[/tex]

Time = 3 minutes = [tex]\frac{3}{60}[/tex] hrs

Speed = 22 mph

[tex]Distance = 22 \times \frac{3}{60}\\\Rightarrow Distance = \dfrac{22}{20}\ miles \\\Rightarrow Distance = 1.1\ miles[/tex]

We know that 1 mile = 5280 feet

Therefore 1.1 miles = 5280 [tex]\times[/tex] 1.1 feet = 5808 feet

Distance traveled by Little Johnny is greater than 4000 feet.

Therefore Johnny will be able to reach the safe zone before the gate is closed.

Answer:

Graph the line  

y = 2 x − 4

After you have plotted the line, shade in the area to right of the line.

To help you to graph the line, two points are  

( 0 , − 4 )  and  ( 2, 0 )

Remember to make it a dashed line to indicate that it is not included.

Here is a how it should look:

Answer:

Here the mistake is that she drew a circle from the point A to intersect the line rather the drawing arcs from the point C

The next another circle was drawn from the point of the intersection of the first circle and the intersection of both circles was used to draw the perpendicular at the midpoint of the intersection of both circles.

Step-by-step explanation:

To construct a line perpendicular to another line through a point the following steps are required

1) From the point, with the compass, C draw  to intersect the line at points A and B

2) From A and B with the compass made wider, draw arcs above and below the line to intersect each other

3) With the straight edge Draw a line passing through the intersections of the arcs drawn from A and B and extend the line to pass through the point C

The line constructed above is the perpendicular to the line l passing through the point C.

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

It’s the opposite

Answer: In order to undo multiplication you must divide. For fractions multiply the reciprocal to get it to the other side in an equation.

Step-by-step explanation:

So it is given that we have to do the opposite operation of multiplication, so that is division. In an equation, if we have a fraction, then we multiply the reciprocal of the fraction to get it to the other side.

Hence, your answer.

Answer:

n = -3

Step-by-step explanation:

Original Equation:

11 (n-1) + 35 = 3n

Distributive Property:

11n + 24 = 3n

Subtract 24 from both sides:

11n + 24 - 24 = 3n - 24

Simplify:

11n = 3n - 24

Subtract 3n from both sides:

11n - 3n = 3n - 24 - 3n

Simplify:

8n = -24

Divide both sides by 8:

[tex] \frac{8n}{8} = \frac{ - 24}{8} [/tex]

Simplify:

n = -3
