How many solutions does this system
have?
6x+3y = 9
2x + y = 3

Answers

Answer 1

Answer:

The system of equation has infinite solution.

Step-by-step explanation

2x + y = 3

6x = 9 – 3y

First we re-write the second equation in standard form

So, we add 3y both sides

6x+3y=9 ---------------- (2)

2x+y = 3-----------------  (1)

3(2x)+3y = 3(3)

6x+3y=9

6x-6x + 3y-3y = 9-9

0=0

LHS=RHS

This is true statement. If statement is true then infinite number of many solution.

Joe has a bag with 10 pink marbles and 20 silver marbles. If he draws a marble from the bag without looking, what is the probability that it will be a pink marble?

Answers

The probability is the ratio of the favorable outcome to the total number of outcomes. Then the probability of a pink marble is 33.33%.

What is probability?

Its simple notion is that something will most likely occur. The favorable event's proportion to the overall number of occurrences.

Joe has a bag with 10 pink marbles and 20 silver marbles.

If he draws a marble from the bag without looking.

Then the probability that it will be a pink marble.

The total number of the event will be

Total event = 20 + 10

Total event = 30

Favorable event = 10

Then the probability will be

P = 10 /30

P = 1/3

P = 0.3333

I am confused about this question ​

Answers

Answer:

X = 5

Step-by-step explanation:

When the line is going vertically down, the x-intercept is always the equation of the line.

Linear Equations of Vertical Lines

Linear equations are typically organized in slope-intercept form:

[tex]y=mx+b[/tex]

m = slopeb = y-intercept (the value of y when the line passes through the y-axis)

However, for vertical line equations, we write them a little differently:

[tex]x=d[/tex]

d = the x-intercept (the value of x when the line passes through the x-axis)

We write equations for vertical lines like this because they might not always have a y-intercept.

Solving the Question

We're given:

Line L passes through the x-axis when x = 5

This means that the x-intercept of the line is 5. Plug this into [tex]x=d[/tex]:

[tex]x=d[/tex]

[tex]x=5[/tex]

Answer

[tex]x=5[/tex]

Chelsea is making a kite in the shape of a triangle. To determine if the triangle is a right triangle, Chelsea completed the following steps.

Step 1:
Find the side lengths of the triangle: 30 inches, 24 inches, 18 inches.

Step 2:
Substitute the values into the Pythagorean theorem: 18 squared + 24 squared = 30 squared.

Step 3:
Combine like terms: (18 + 24) squared = 30 squared.

Step 4:
Evaluate each side: 1764 not-equals 900.

Chelsea says the triangle is not a right triangle. Which best describes the accuracy of her explanation?

Answers

She made a mistake on step 3

The [tex]18^2+24^2[/tex] is not the same as [tex](18+24)^2[/tex]

This is what her steps should look like

[tex]a^2 + b^2 = c^2\\\\18^2 + 24^2 = 30^2\\\\324 + 576 = 900\\\\900 = 900\\\\[/tex]

Since we get the same number on both sides, this means the last equation is true. This means the first equation is also true. Therefore, she does have a right triangle. Refer to the converse of the pythagorean theorem for more info.

cone is 33 CUBIC INCHES. WHAT IS THE
Volume OF THE CYLINDER IN CUBIC
inches?
125 Sunny

Answers

Answer:

99 in³

Step-by-step explanation:

Let the radius and height of each be r and h in. respectively.

Write an equation for the volume of cone.

Volume of cone= ⅓πr²h

⅓πr²h= 33

Multiply both sides by 3:

πr²h= 99

Volume of cylinder= πr²h

We have found the value of πr²h previously, which is 99.

Thus, the volume of the cylinder is 99 in³.

5. Ten kids each order a scoop of ice
cream. Five of the kids add sprinkles,
3 add nuts, and 2 add nothing extra.
Write and simplify an expression that
represents the total cost.

Answers

So, the simplified expression that represents the total cost is 8(x + 0.34375) dollars.

What is cost?

Let x be the cost of one scoop of ice cream without any toppings. Then the total cost for each kid who adds sprinkles is x + 0.25, the total cost for each kid who adds nuts is x + 0.35, and the total cost for each kid who adds nothing extra is x.

Therefore, the total cost for the 10 kids is:

5(x + 0.25) + 3(x + 0.35) + 2x = 8x + 2.75

Simplifying this expression, we get:

8x + 2.75 = 8(x + 0.34375)

Answers

Answer:

Given that certificate of deposits earns 0.75% interest every three months, the value of $25,000 after 8 years will be:

A=P(1+r/100)^nt

where:

A=amount

P=principle

r=rate

t=time

n=number of terms

thus:

from the infomation

$25000, r=0.75%, t=8 years, n=12/3=4

thus

A=25000(1+0.0075/100)^(4*8)

A=25000(1.0075)^32

A=$3175.28

The fifth term of a geometric sequence is 781.25. Each term of the sequence is 1/5 of the value of the following term. Which recursive formula represents the situation?

Answer choices are in the image attached.

Answers

The recursive formula of the geometric sequence is [tex]a_{n} = 5a_{n-1}[/tex] and a1 = 1.25

How to determine the recursive formula?

The given parameters are:

Fifth term = 781.25

Term = 1/5 * following term

The second parameter above means that:

[tex]a_n = \frac{1}{5} * a_{n+ 1}[/tex]

Multiply both sides by 5

[tex]a_{n+1} = 5a_n[/tex]

Remove 1 from the terms

[tex]a_{n} = 5a_{n-1}[/tex]

Using the formula [tex]a_n = \frac{1}{5} * a_{n+ 1}[/tex], we have the first term to be:

[tex]a_1 = \frac 15 * a_2[/tex]

[tex]a_2 = \frac 15 * a_3[/tex]

[tex]a_3 = \frac 15 * a_4[/tex]

[tex]a_4 = \frac 15 * a_5 = \frac 15 * 781.25 = 156.25[/tex]

So, we have:

[tex]a_3 = \frac 15 * 156.25 = 31.25[/tex]

[tex]a_2 = \frac 15 * 31.25 = 6.25[/tex]

[tex]a_1 = \frac 15 * 6.25 = 1.25[/tex]

Hence, the recursive formula is [tex]a_{n} = 5a_{n-1}[/tex] and a1 = 1.25
