Answer:
1 and - 2
Step-by-step explanation:
f(- 3) means what is the value of y when x = - 3
When x = - 3 the corresponding point is (- 3, 1 ) ← with y = 1, thus
f(- 3) = 1
Similarly for f(0)
When x = 0 the corresponding point is (0, - 2 ) ← with y = - 2 , thus
f(0) = - 2
How much money should be invested in an account that earns 8% interest compounded quarterly to yield $10,000 in 4 years? (Round your answer to the nearest cent.)
Answer:
757,576cents
Step-by-step explanation:
Given
Amount = $10000
Time = 4years
Rate = 8%
n = 1/4 year (compounded quarterly
Using the formula to get the principal
A = P(1+r/n)^nt
10000 = P(1+0.08/0.25)^4(1/4)
10000 = P(1+0.32)
10000= 1.32P
P = 10000/1.32
P = 7575.76
Hence he suppose to invest $7575.76 which is equivalent to 7575.76×100 cents i.e 757,576cents

Relaciona correctamente cada número con sus respectivos múltiplos: 1) 14135 2) 11234125723 A) múltiplo de 3 B) múltiplo de 5 C) múltiplo de 11
Answer:
1) 14135 = B) múltiplo de 5 C) múltiplo de 11
Step-by-step explanation:
Para saber si un numero es un multiplo de otro simplemente tenes que dividir el otro numero por el primero y si el resultado es un numero entero (sin resto y que no es un decimal) entonces es un multiplo de ese numero. En esta pregunta el primer numero (14135) es multiplo de 5 y de 11 por que al dividir no quedan restos, pero no es multiplo de 3 por que si quedan restos.
14135 / 3 = 4,711.666
14135 / 5 = 2,827
14135 / 11 = 1,285
El segundo numero (11234125723) no es multiplo de ninguna de las opciones por que todos dejan restos.
11,234,125,723 / 3 = 3,744,708,574.33333
11,234,125,723 / 5 = 2,246,825,144.6
11,234,125,723 / 11 = 1,021,284,156.636363

Find the value of x and the measure of each angle:
1. x =
2. m∠5x + 62 =
3. m∠3x + 47 =
Answer:
Step-by-step explanation:
Find the supplement of 5x + 62
Call the supplement = z
5x + 62 + z = 180 Subtract 5x + 62 from both sides
z = 180 - (5x + 62) Remove the brackets
z = 180 - 5x - 62
z = 118 - 5x
Add the 3 angles to 180
37 + 3x + 47 + 118-5x = 180 All triangles have 180 degrees. Combine like terms
202 - 2x = 180 Subtract 202 from both sides
-2x = - 22 Divide by -2
x = -22/-2
x = 11
======================
x = 11
5x + 62 = 5*11 + 62 = 55 + 62 = 117
3x + 47 = 3*11 + 47 = 33 + 47 = 80
Note these do not add up to 180. That's because 5x + 63 is outside the triangle.
The supplement of 117 = 63
37 + 63 + 80 = 180 as it should.

Amanda sells homemade birthday cakes for a profit of $39 per cake. She is considering switching to a new type of icing that will increase her profit, as expressed by the function y = 45x, where x is the number sold and y is the amount of profit.
How many more dollars will Amanda earn on each cake if she switches to the new material? Explain how you found your answer. (5 points)
Answer:
6
Step-by-step explanation:
Her profit will increase be 6 dollars.
x = 1
y = 45(1)
y = 45
The number of more dollars earned by Amanda if she switched to new icing will be $6.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties
Given that Amanda sells homemade birthday cakes for a profit of $39 per cake. She is considering switching to a new type of icing that will increase her profit, as expressed by the function y = 45x, where x is the number sold and y is the amount of profit.
The number of dollars will be calculated as,
y = 45x
For 1 cake the profit with new icing is,
y = $45
The more number in profit is calculated as,
P = 45 - 39
P = $6
Therefore, the number of more dollars earned by Amanda if she switched to new icing will be $6.

[tex]\mathfrak{\huge{\pink{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the Concept of the AP.
1.) For the first Sequence, d= 4
so we get as, an = a + (n-1) d
an = 9/2 + (n-1) 4
an = 9/2 +4n -4
=> an = 1/2 + 4n
2.) d = 3
=> an = 10/3 + (n-1) 3
so, => an = 10/3 +3n -3
=> an = 1/3 +3n
3.) d = -0.2
=> an = 1/2 +(n-1) (-0.2)
=> an = 1/2 -0.2n +0.2
=> an= 0.7 -0.2n

The ratio of the measure of the three angles in a triangle is 2:9:4. Find the measures of the angle.
Answer:
Let the measures of three angles be 2x, 9x, 4x
Sum of the angles of a triangle = 180
2x+9x+4x = 180
15x = 180
x = 180/15 = 12
First angle = 2x = 2*12 = 24°
Second angle = 9x = 9*12 = 108°
Third angle = 4x = 4*12 = 48°

Marissa wants to blend candy selling for $1.80 per pound with candy costing $1.20 per pound to get a mixture that costs her $1.40 per pound to make. She wants to make 90 pounds of the candy blend. How many pounds of each type of candy should she use?
Answer: 30 lb of $1.80 candy
60 lb of $1.20 candy
Step-by-step explanation:
let ( x )represent the pounds of $1.80 candy.
Then 90-x will be pounds of $1.20 candy, • Total mix
= 1.80x + 1.20(90-x)
But because we the value to be same as 90 pounds of $1.40 per pound mix, so the equation
= 1.80x + 1.20(90 -x) = 1.40(90)
Simply the equation
= 1.80x + 108 - 1.20x = 126
= 0.60x + 108 = 126
0.60x = 126 - 108
0.60x = 18
divide both sides by 0.60
x = 30.
30 lb is the pounds of $1.80 candy
Substitute x into 90-x
90 - 30
= 60.
pounds of $1.20 candy Is 60 lb.
