Answer:
Composite number
Step-by-step explanation:
Prime numbers are whole numbers that have 2 factors of 1 and itself.Composite numbers are whole numbers that have factors of more than two factors. They can also be found by multiplying two or more smaller numbers.Factors of 38:
1 * 38
2 * 19
1, 2, 19, 38
Therefore, 38 is not a prime, but rather a composite number.

Step-by-step explanation:
7. Since they are similar triangles we have:
[tex] \frac{10}{8} = \frac{x}{12} \\ \\ x = 15[/tex]
So DF is 15
8. They are also similar. So:

State the center and radius of each circle. then write the equation of the circle in standard form.
See attached:
Answer:
Step-by-step explanation:
Center: (h, k) (the coordinate of the middle point)r(radius): d(diameter)/2 (can be found by counting the number of units vertically or horizontally)Standard form of a circle: (x - h)² + (y - k)² = r²1.
Center: (-2, 3)
Radius: 10/2 = 5
Standard form/ equation: (x + 2)² + (y - 3)² = 25
Standard form:
(x - (-2))² + (y - 3)² = 5²
(x + 2)² + (y - 3)² = 25
2.
Center: (1, 1)
Radius: 6/2 = 3
Standard form/ equation: (x - 1)² + (y - 1)² = 9
Standard form:
(x - 1)² + (y - 1)² = 3²
(x - 1)² + (y - 1)² = 9
Hope this helps!

Answer:
(y + 3)² - 8
Step-by-step explanation:
y² + 6y +1
Step 1: Divide the co efficient of y by 2

Step2: Now find the square of 3
3² = 9
Step3: Add and subtract 9
y² + 6y + 9 - 9 + 1 = y² +6y + 9 - 8

12x + 3y = 9 solve for y
Answer:
[tex]\Longrightarrow: \boxed{\sf{y=3-4x}}[/tex]
Step-by-step explanation:
To solve for y, you have to isolate it on one side of the equation.
12x+3y=9First, you have to subtract by 12x from both sides.
[tex]\Longrightarrow:\sf{12x+3y-12x=9-12x}[/tex]
Solve.
[tex]\Longrightarrow:\sf{3y=9-12x}[/tex]
Then, you divide by 3 from both sides.
[tex]\Longrightarrow:\sf{\dfrac{3y}{3}=\dfrac{9}{3}-\dfrac{12x}{3}}[/tex]
Solve.
[tex]\sf{\dfrac{9}{3}-\dfrac{12x}{3}}[/tex]
[tex]\sf{\dfrac{9-12x}{3}}[/tex]
Use the distributive property.
[tex]\underline{\text{DISTRIBUTIVE PROPERTY:}}[/tex]
⇒A(B+C)=AB+AC9-12x=3(3-4x)
[tex]\sf{\dfrac{3\left(3-4x\right)}{3}}[/tex]
Divide the numbers from left to right.
3/3=1
3-4x
Then, rewrite the problem down.
[tex]\Longrightarrow: \boxed{\sf{y=3-4x}}[/tex]
Therefore, the correct answer is y=3-4x.I hope this helps! Let me know if you have any questions.
Answer:
y = (3) - (4x)
Step-by-step explanation:
Note: Since there is only one equation given, the value of "y" will not be a fixed value.
Given equation:
12x + 3y = 9Our main goal to solve for "y" is to have the y-variable on one side, and a specific value or variable on the other side (e.g., y = 3 or y = 4x) . Start out by subtracting both sides by 12x. This will isolate the y-variable and it's cooeficient (3).
⇒ 12x + 3y = 9⇒ 12x + 3y - 12x = 9 - 12x⇒ 3y = 9 - 12xOnce the y-variable and the cooeificent of the variable have been isolated, we can divide both sides by the cooeficient to isolate the variable.
⇒ 3y/3 = (9 - 12x)/3⇒ y = (9 - 12x)/3⇒ y = (9 ÷ 3) - (12x ÷ 3)⇒ y = (3) - (4x)Therefore, the value of "y" is 3 - 4x.
Manuel labore earns $19. 50/hr. And works an average of 38 hours a week. He is considering renting a house for $1,700/ month. His real estate friend recommends he spend no more than 28% of his monthly income on housing.
Answer:
Given:
Wage = $19.50 per hourWeekly hours worked = 38⇒ Weekly income = 38 × $19.50 = $741
⇒ Monthly income = ($741 × 52.14) ÷ 12 = $3219.65
28% of monthly income
= 0.28 × $3219.65 = $901.50
As $1700 > $901.50 Manuel should not rent the house for $1700 per month since it is more than 28% of his income.
The cost of rent at $1700 per month is actually 52.8% of his monthly income:
(1700 / 3219.65) x 100 = 52.8%

What is the arc of a circle?The arc of a circle is defined as the part or segment of the circumference of a circle.
Given that, a circle, Chords NO and PQ are congruent. Arc NO measures 4x + 10 and Arc PQ measures 2x + 20.
We know that,
Chord Arcs Theorem :-
If two chords in a circle are congruent, then their intercepted arcs are congruent.
2x+20 = 4x+10
2x = 10
x = 5
Therefore,

Wendy drives a car 110 kilometers per hour. What is this rate, in miles per hour, to the nearest tenth?
Answer:
68.3 miles per hour
Step-by-step explanation:
One kilometer is 0.62 miles.
110 times 0.62 is 68.3
Wendy's rate of 110 kilometers per hour is 68.3 miles per hour.
To convert kilometers per hour to miles per hour, we need to use the conversion factor of 1 kilometer = 0.621371 miles.
Given that Wendy drives at a rate of 110 kilometers per hour.
we can multiply this value by the conversion factor to obtain the equivalent rate in miles per hour.
110 kilometers per hour × 0.621371 miles per kilometer
= 68.34381 miles per hour
We get 68.3 miles per hour.

The function f is defined by f(x) = x^2 + 3x -10 , if f(x + 5) = x^2 + kx + 30, k=
Answer:
k = 13
Step-by-step explanation:
substitute x = x + 5 into f(x) , that is
f(x + 5) = (x + 5)² + 3(x + 5) - 10 ← expand squared factor using FOIL
= x² + 10x + 25 + 3x + 15 - 10
= x² + 13x + 30
