5. If x^1/2 =8, what is the value of x?

Answer: 7

pounds for 3.15 is a better option

Step-by-step explanation:

Here in this question, we want to know which of the two options is a better option for buying crickets.

To know the better option, we shall be needing the unit price in whatever system to be used;

7 pounds of crickets for 3.15;

so the unit price here will be 3.15/7 = 0.45 per pound

For the second system, we have 3 pounds for 1.47 so the unit price will be 1.47/3 = 0.49 per pound

As we can see, the first option commands a cheaper price per unit, so it is the better option to buy

Answer:

x = 3

Step-by-step explanation:

12 = 7x + 6 -5x        {Combine like terms}

12 = 7x - 5x + 6

12 = 2x + 6           {Subtract 6 from both sides}

12 - 6 = 2x

      6 = 2x                  {Divide both sides by 2}

    6/2 = 2x/2

3 = x

x = 3

Multiply both sides by negative four to get rid of the fraction

j+18=-32

subtract 18

j=-50

Answer:

Step-by-step explanation:

each mark represents 0.25

Decimal value positioned at point B is -2.25

A number system is defined as a system of writing to express numbers.

A number line can be defined as a pictorial representation of numbers on a straight line.

In the given number line each line represents 0.25 (zero point two five value).

As B is in between -2 and -3.

So B value is between minus two and minus three

The values which can be between -2 and -3 are -2.25, -2.5, -2.75.

The decimal value positioned at point B is -2.25

Hence decimal value positioned at point B is -2.25

Greetings from Brasil...

As we have a line, the function will be given by the expression:

F(X) = AX + B

where

A = ΔY/ΔX

B = where the line intersects the Y axis

Looking at the graph we have already concluded that

B = - 3

A = ΔY/ΔX

A = (5 - 3)/(4 - 3)     see attached picture

A = 2

So,

F(X) = AX + B

→ Collinear points = points belonging to the same line

→ PQ is said to be equal to RS. Let’s call this distance X

→ let's call QR Y

With this information and the figure in the annex we can conclude that:

refer to attached

PQ = X

QR = Y

RS = PQ = X

then

PR = PQ + QR

16 = X + Y       i

PS = PR + RS

21 = 16 + X

X = 5       putting in i

16 = X + Y

16 = 5 + Y

Y = 11

So,

Collinear points are points on the same line.

The value of QR is 11

From the question, we have:'

This means that:

[tex]\mathbf{PR = PQ + QR}[/tex]

[tex]\mathbf{QS = QR + RS}[/tex]

[tex]\mathbf{PS = PR + RS}[/tex]

The given parameters are:

[tex]\mathbf{PS = 21}[/tex]

[tex]\mathbf{PR = 16}[/tex]

[tex]\mathbf{PQ = RS}[/tex]

Substitute the above values in [tex]\mathbf{PS = PR + RS}[/tex]

[tex]\mathbf{21= 16 + RS}[/tex]

Solve for RS

[tex]\mathbf{RS = 21- 16}[/tex]

[tex]\mathbf{RS = 5}[/tex]

This means that:

[tex]\mathbf{PQ = RS = 5}[/tex]

Substitute 5 for PQ in [tex]\mathbf{PR = PQ + QR}[/tex]

[tex]\mathbf{PR = 5+ QR}[/tex]

Substitute [tex]\mathbf{PR = 16}[/tex] in [tex]\mathbf{PR = 5+ QR}[/tex]

[tex]\mathbf{16 = 5+ QR}[/tex]

Solve for QR

[tex]\mathbf{QR = 16 - 5 }[/tex]

[tex]\mathbf{QR = 11}[/tex]

Hence, the value of QR is 11

Hope that will help you

Answer:

Step-by-step explanation:

9/100 i believe as you would multiply 3/10 by 3/10 due to the fact the marble is being replaced so the probability of getting a red marble the second time will be more unlikely. If I'm right please thank me or give me brainly. Hope this helps :)

The probability of drawing two red marbles, if the first marble is replaced after it is drawn, is 9/100.

What is Probability?

It is a branch of mathematics that deals with the occurrence of a random event.

The probability of drawing a red marble on the first draw is 3/10, since there are 3 red marbles out of a total of 10 marbles.

Since the first marble is replaced before the second draw, the probability of drawing a red marble on the second draw is also 3/10.

To find the probability of drawing two red marbles in a row, we multiply the probabilities of the individual events, since they are independent:

P(drawing two red marbles) = P(red on first draw) × P(red on second draw)

P(drawing two red marbles) = (3/10) × (3/10)

= 9/100

Therefore, the probability of drawing two red marbles, if the first marble is replaced after it is drawn, is 9/100.

Answer:

D. 80

Step-by-step explanation:

Given:

f(x) = 5x - 4,

g(x) = x² - 1

Required:

(g o f)(-1)

SOLUTION:

(g o f)(-1) = g(f(-1))

Plug in -1 for x into the function, f(x) = 5x - 4:

g(f(-1)) = g(5(-1) - 4)

= g(-5 - 4)

= g(-9)

Plug in -9 for x in the function, g(x) = x² - 1

g(-9) = (-9)² - 1

= 81 - 1

= 80.

Therefore, (g o f)(-1) = g(f(-1)) = 80

D. 80 is the correct answer.

Answer:

f(x)= 3|x-3|+1

Step-by-step explanation:

Reason why it's not +3 is because it's the reverse when graphed. But that only applies for the numbers in the brackets. If it's in the brackets and it's positive, you go to the left. If it's negative, then it goes to the right. And as you see, the V isn't on the point (0 , 3), and is in fact, above it, by 1. The graph has also been stretched vertically by 3, it looks like.

Answer:

y = 2|x-3| + 1

Step-by-step explanation:

The vertex of g(x) = |x| is at (0,0)

We have moved the vertex to ( 3,1)

y = f(x) + C  C > 0 moves it up

y = |x| + 1 for the shift up 1

y = f(x + C)  C < 0 moves it right

y = |x-3|  for the shift to the right 3

y = Cf(x)  C > 1 stretches it in the y-direction

y = 2|x| since  it is stretched by a factor of 2 in the y direction

Combining

y =2|x-3| + 1

Answer:

y = -2x - 8

Step-by-step explanation:

Parallel lines always have the same slope. Here, it is -2.

So, our equation so far looks like this:

y = -2x + b, where b is the y-intercept

We need to find b. We know our line passes through (-4, 0), so let's plug -4 in for x and 0 in for y:

y = -2x + b

0 = -2 * (-4) + b

0 = 8 + b

b = -8

Since b = -8, our equation is thus y = -2x - 8.
