Let x be the price of a backpack. Which inequality represents prices
that are more than $15?
A:2 < 15
B:2 > 15
C:< -15
D:2 > -15

Answer:

1 cm = 3 feet.

Step-by-step explanation:

Divide 15 by 5 to get 3; on the blueprint, every centimeter represents 3 feet.

The scale of scale factor of the blueprint is 1 cm = 3 feet.

The scale factor defines a variable in a ratio of two different measurements.

Sometimes drawings of large models are represented in a scale factor of a smaller unit.

Given, On a blueprint, the length of a wall is 5 centimeters and the actual length of the wall is 15 feet.

Therefore, The scale factor of the blueprint is,

= (5/15).

= 1/5.

So, It can be written as 1 cm = 3 feet.

Answer:

70 cups

Step-by-step explanation:

C. P. of lemonade supplies = $5.25

S. P. of one cup of lemonade = $1.50

Let us assume that she should sell n cups of lemonade to make a profit of $100.00.

Therefore, S. P of n cups = $1.50n

Since,

Profit = S. P. - C. P.

Therefore,

100 = 1.5n - 5.25

100 + 5.25 = 1.5n

105.25 = 1.5n

n = 105.25/1.5

n = 70.1666667

n = 70 cups

Step-by-step explanation:

When you reflect across the x axis you have to flip the sign of the y coordinate. When you reflect across the x axis you have to flip the sign of the x coordinate.

Answer:

(−2 1/2, 2)

Step-by-step explanation:

Since, one palm tree is located at (−2 1/2, −2). The other palm tree is a reflection of point T across the x-axis.

Therefore, for other palm tree x- coordinate will remain same and y-coordinate will flip over x- axis to become positive.

Thus, the coordinates of point R would be (−2 1/2, 2)

3y = -2x

y = x - 5

Step 2: Solve for x

Substitution

Step 3: Solve for y

Answer:

y = -2

x = 3

Step-by-step explanation:

First plug in the y= x-5 equation into the 3y = -2x so that it looks like this:

3(x-5)=-2x

Second after distributing the 3 to the x and -5 you will have an equation that looks like this: 3x -15 = -2x

Then you have keep the x's on one side so you add 2x to both sides and add 15 as well so now you have: 5x = 15

Divide both sides by 5 and get x = 3

To find y, you plug x=3 in in to the y = x-5 and get that y = -2

~theLocoCoco

Answer:

35 years old

Step-by-step explanation:

Since your brother is half your age, that means it should be exact. 70 is not a number than would have an even split, so you would have to have either an odd number such as 5. 40 plus 40 is 80, which is to high. 30 plus 30 is 60, too low. 35 plus 35 is 70 exact. Hope this helped! Also, I dont know if this was trick question, either way, he should be half. So if you were 10, he would be 5. If you were 18, he would be 9.

Answer:

36 units squared

Step-by-step explanation:

Since this is kind of a weird shape, we can split it into two smaller shapes, a triangle, and a rectangle.  

The rectangle is 6 units wide, and 4 units long.  Multiply the length and width to get 24 units squared.  

The triangle has a base of 6 and a height of 4, so multiply the base and height, then divide by 2.  6 times 4 is 24 and that divided by 2 is 12.  

Finally add the two areas together.  24+12=36 units squared.

Answer:

36

Step-by-step explanation:

Since the two triangles on the bottom are the same, we can flip one of them over onto the other, and they will make a square. Then the top rectangle is 24, and the bottom new square would be 12 and 24 plus 12 is  36

Answer:

Answer:

An explicit representation for the nth term of the sequence:

[tex]f_n=-\frac{1}{2}\cdot \:4^{n-1}[/tex]

It means, option (B) should be true.

Step-by-step explanation:

Given the geometric sequence

[tex]-\frac{1}{2},\:-2,\:-8,\:-32,...[/tex]

A geometric sequence has a constant ratio, denoted by 'r', and is defined by

[tex]f_n=f_1\cdot r^{n-1}[/tex]

Determining the common ratios of all the adjacent terms

[tex]\frac{-2}{-\frac{1}{2}}=4,\:\quad \frac{-8}{-2}=4,\:\quad \frac{-32}{-8}=4[/tex]

As the ratio is the same, so

r = 4

Given that f₁ = -1/2

substituting r = 4, and f₁ = -1/2 in the nth term

[tex]f_n=f_1\cdot r^{n-1}[/tex]

[tex]f_n=-\frac{1}{2}\cdot \:4^{n-1}[/tex]

Thus, an explicit representation for the nth term of the sequence:

[tex]f_n=-\frac{1}{2}\cdot \:4^{n-1}[/tex]

It means, option (B) should be true.

Answer:

x = 4 and x = -4

x = 1 and x = -1

Step-by-step explanation:

let u = x^2

Then,

u^2-5u+4 = 0

(u - 4)(u - 1) = 0

u = 4 and u = 1

we substitute back for u

Then,

x^2 = 4

x = 4 and x = -4

x^2 = 1

x = 1 and x = -1

The solutions to the equation x⁴ - 5x² + 4 = 0 are x = ±2 and x = ±1.

To solve the equation x⁴ - 5x² + 4 = 0, we can use substitution to simplify it.

Let's take a new variable, u = x².

Substituting u into the equation, we get:

u² - 5u + 4 = 0

Now, we can factor this quadratic equation:

(u - 4)(u - 1) = 0

Setting each factor equal to zero, we have:

u - 4 = 0 or u - 1 = 0

Solving for u in each case:

u = 4 or u = 1

Now, we substitute back the original variable x:

For u = 4:

x² = 4

Taking the square root of both sides:

x = ±2

For u = 1:

x² = 1

Taking the square root of both sides:

x = ±1

Therefore, the solutions to the equation x⁴ - 5x² + 4 = 0 are x = ±2 and x = ±1.

Answer:

(x+4) * (x+3)

Step-by-step explanation:

To factor the general expression:

X²+ax+c

We need to find the numbers b and d of the factoring expression:

(x+b) * (x+d)

Where:

b*d = c

b+d = a

For the expression:

X²+7x+12

We need to find b and d that:

b+d = 7

b*d = 12

If b = 4 and d = 3, the expression could be:

(x+4) * (x+3) = X² + 4x + 3x + 12 = X² + 7x +12

Answer:

2

Step-by-step explanation:

We have the equation

[tex]m^{5/6}(m^{1/6})^7=m^x[/tex]

The exponent rules to be used are

[tex]a^x\times a^y=a^{x+y}[/tex]

[tex](a^{x})^y=a^{xy}[/tex]

[tex]m^{5/6}(m)^{7/6}=m^x\\\Rightarrow m^{\dfrac{5}{6}+\dfrac{7}{6}}=m^x\\\Rightarrow m^{\dfrac{5+7}{6}}=m^x\\\Rightarrow m^{\dfrac{12}{6}}=m^x\\\Rightarrow m^{2}=m^x[/tex]

Comparing the exponents we get

[tex]x=2[/tex]

So, the value of [tex]x=2[/tex] makes the equation true.
