The solutions to f(x) = 64 is x = 7 and x = –7.
Solution:
Given data:
[tex]$f(x)=x^{2}+15[/tex] – – – – (1)
[tex]f(x)=64[/tex] – – – – (2)
To find the solutions to f(x) = 64.
Equate equation (1) and (2), we get
[tex]x^2+15=64[/tex]
Subtract 15 from both sides of the equation.
[tex]x^2+15-15=64-15[/tex]
[tex]x^2=49[/tex]
[tex]x^2=7^2[/tex]
Taking square root on both sides of the equation, we get
x = ±7
The solutions to f(x) = 64 is x = 7 and x = –7.

A box is filled with 8 blue cards, 8 yellow cards, and 2 green cards. A card is chosen at random from the box. What is the probability that the card is not yellow?
The probability that the card is not yellow is [tex]\frac{5}{9}[/tex]
Solution:
The probability of an event is given as:
[tex]Probability = \frac{ \text{ number of favorable outcomes }}{ \text{ total number of possible outcomes }}[/tex]
From given,
A box is filled with 8 blue cards, 8 yellow cards, and 2 green cards
Total number of possible outcomes = 8 + 8 + 2 = 18
Favorable outcome = card is not yellow
Favorable outcome = card is blue or green = 8 + 2 = 10
Therefore,
[tex]Probability = \frac{10}{18}\\\\Probability = \frac{5}{9}[/tex]
Thus the probability that the card is not yellow is 5/9
The probability that the chosen card is not yellow = [tex]\frac{5}{9}[/tex]
Step-by-step explanation:
Step 1 :
Given,
Number of blue cards in the box = 8
Number of yellow cards in the box = 8
Number of green cards in the box = 2
Hence total number of cards = 18
We need to find the probability that the chosen card is not yellow.
Step 2 :
Probability that the selected card is yellow = [tex]\frac{8}{18}[/tex] = [tex]\frac{4}{9}[/tex] [since the favorable outcome = 8 and total outcome = 18]
Hence the probability of chosen card not being yellow = 1 - [tex]\frac{4}{9}[/tex] = [tex]\frac{5}{9}[/tex]
Step 3 :
Answer :
The probability of chosen card not being yellow = [tex]\frac{5}{9}[/tex]

1. Moesha needs $79 for a class trip. 59
She already has $22 and she can earn
the rest by babysitting for 8 hours.
If h represents her hourly earnings,
which of the following equations can
be solved to find Moesha's hourly
earnings? Select all that apply.
Answer: 79=8h +22
Step-by-step explanation: 79 total needed 8h equals 8 times her hourly earning plus 22 what she already haves should equal 79.
Final answer:
To find Moesha's hourly earnings for babysitting, we subtract the amount she already has ($22) from the total needed ($79) to calculate the amount she needs to earn ($57), and divide this by the number of hours she will babysit (8). This gives us the equation 8h = $57, which we solve by dividing both sides by 8, leading us to find that Moesha earns $7.125 per hour.
Explanation:
Moesha needs $79 for a class trip and already has $22. She will earn the remaining amount by babysitting for 8 hours. If we use h to represent Moesha's hourly earnings, we need to set up an equation that when solved, will find her hourly earnings. The total amount Moesha needs to earn from babysitting is $79 - $22, which equals $57. Since she is babysitting for 8 hours, we divide the total amount she needs to earn by the number of hours she will work: $57 ÷ 8 hours.
Putting this into an equation, we come up with 8h = $57. To find her hourly earnings, h, we divide both sides of the equation by 8, giving us h = $7.125 per hour. Therefore, Moesha will earn $7.125 for each hour of babysitting she does.

help fast plz.
Answer:
A number line going from 50 to 60. A solid circle is at 54. Everything to the right of the circle is shaded.
Step-by-step explanation:
we have the inequality
[tex]11\leq y-43[/tex]
solve for y
Adds 43 both sides
[tex]11+43\leq y[/tex]
[tex]54\leq y[/tex]
Rewrite
[tex]y\geq 54[/tex]
In a number line the solution is the shaded area at right of y=54 (closed circle)
therefore
A number line going from 50 to 60. A solid circle is at 54. Everything to the right of the circle is shaded.

Solve this equation for x in terms of y and z
7x - 5y - 2z = 4
What is he value of x when y = 5 and z = 3
Answer:
x = 5
Step-by-step explanation:
Step 1: Set y to 5 and z to 3
7x - 5(5) - 2(3) = 4
7x - 25 - 6 = 4
7x - 31 = 4

How do I solve for what is sin A for the triangle shown
Option a:
sin A for the triangle is [tex]\frac{3}{5}[/tex].
Solution:
The given triangle is a right triangle.
The adjacent side to angle A is AC.
The opposite side to angle A is BC.
Hypotenuse is AB.
AC = 8, BC = 6 and AB = 10.
Using trigonometric ratio formulas,
[tex]$\sin \theta=\frac{\text { Opposite side }}{\text { Hypotenuse }}[/tex]
[tex]$\sin A=\frac{BC}{AB}[/tex]
[tex]$\sin A=\frac{6}{10}[/tex]
Divide both numerator and denominator by 2, we get
[tex]$\sin A=\frac{6\div2}{10\div 2}[/tex]
[tex]$\sin A=\frac{3}{5}[/tex]
Hence sin A for the triangle is [tex]\frac{3}{5}[/tex].
Option a is the correct answer.

What Are The Factors Of The Expression? -X2+2x+35
A. -1(X-5)(X+7)
B. (X-5)(X-7)
C. -1(X+5)(X-7)
B. (X+5)(X-7)
For this case we must factor the following expression:
[tex]-x ^ 2 + 2x + 35[/tex]
We take common factor -1, taking into account that [tex]- * - = +:[/tex]
[tex]-1 (x ^ 2-2x-35)[/tex]
We factor the expression within the parenthesis, for this we look for two numbers that, when multiplied, result in -35 and when added, result in -2. These numbers are -7 and +5.
[tex]-7 + 5 = -2\\-7 * 5 = -35[/tex]
Thus, the factored expression is:

Paul, Fiona and Pip share some sweets in the ratio 4:1:1. Paul gets 48 sweets. How many did Pip get?
Answer:
12
Step-by-step explanation:
4:1:1, from the ratio, you know that there are 6 in total (4+1+1)
so set up a proportion
(4/6) = (48/x)
so... (6 x 48) / 4 = x
x = 72, the total
now repeat to find the value for Pip
(1/6) = (x/72)
72 / 6 = 12
Final answer:
Paul, Fiona, and Pip share sweets in a 4:1:1 ratio. Paul's 4 parts amount to 48 sweets, so each part is 12 sweets. Consequently, Pip receives 12 sweets.
Explanation:
The student's question is asking how many sweets Pip would get if Paul, Fiona, and Pip share some sweets in the ratio 4:1:1 and Paul gets 48 sweets. To solve this, we'll need to break down the problem and figure out how many parts the total number of sweets is being divided into. Then, we'll calculate the number of sweets per part using the information given.
Since the ratio is 4:1:1, there are a total of 4 + 1 + 1 = 6 parts. Paul's share is 4 parts, and since Paul gets 48 sweets, each part is worth 48 sweets ÷ 4 parts = 12 sweets.
Both Fiona and Pip get 1 part each. So, since each part equals 12 sweets, Pip gets 12 sweets.
