Answer:
C.18(38) +2.5s >/= 750
Step-by-step explanation:
If Patty earns $18 an hour, plus an additional $2.50 each time one of her customers completes survey and Patty plans to work 38 Hours then the inequality which shows the earning of atleast $750 is 18(38)+2.5s>=750 which is option C.
What is inequality?Inequality is like an equation which shows the relationship between two or more variables but it is expressed in greater than, less than, greater than or equal to, less than or equal to signs.
How to form inequality?We have been given that the number of surveys is s.
Earning on the basis of hours=18*38
Earning from customer's survey=s*2.50
Earning required by Patty=$750
Inequality which shows atleast $750 earning of Patty is :
18*38+2.50s>=750
we have to use greater than sign because the earning that Patty wants to earn is atleast 750 so it can be equal to or more than 750 dollars.
Hence the inequality will be 18(38)+2.5s<=750.

19. Write the perimeter of the rectangle as a
simplified expression.
x - 3
7x + 1
Answer:
16x - 5
Step-by-step explanation:
2(x-3) + 2(7x+1) since there are 4 sides, 2 which have the same dimensions
2x - 6 + 14x + 1 = 16x - 5
The simplified expression of the perimeter of the rectangle should be 16x - 4.
Given that
x - 37x + 1We know that
The perimeter of the rectangle be
= 2(length + breadth)
= 2(x - 3 + 7x +1)
= 2x - 6 + 14x + 2
= 16x - 4
Therefore we can conclude that the simplified expression of the perimeter of the rectangle should be 16x - 4.

Given the following three points, find by hand the quadratic function they represent.
(-1,-8), (0, -1),(1,2)
(1 point)
O f() = -5x2 + 8x - 1
Of(x) = -222 +50 - 1
O f(x) = -3.x2 + 4.0 – 1
O f() = -3x2 + 10x - 1
Answer:
The equation is;
f(x) = -2·x² + 5·x - 1
Step-by-step explanation:
The general form of a quadratic equation or function f(x) is, f(x) = y = a·x² + b·x + c
Given that the points representing the quadratic function are;
(-1, -8), (0, -1), (1, 2) which are of the form (x, y)
When x = -1, f(x) = y = -8
Plugging in the above values into the general form of a quadratic function, we have;
-8 = a·(-1)² + b·(-1) + c = a - b + c
-8 = a - b + c.........................(1)
When x = 0, y = -1, we have;
-1 = a·(0)² + b·(0) + c = c
c = -1.......................................(2)
When x = 1, y = 2, which gives;
2 = a·(1)² + b·(1) + c = a + b + c
2 = a + b + c........................(3)
Adding equation (1) to equation (3), we have;
-8 + 2 = a - b + c + a + b + c
-8 + 2 = 2·a + 2·c
From equation (2) c = -1, we get;
-8 + 2 = -6 = 2·a + 2·c = 2·a + 2 × (-1)
-6 = 2·a - 2
-4 = 2·a
a = -2
From equation (3), we have
2 = a + b + c
Substituting the values of a, and c gives;
2 = -2 + b - 1
b = 2 + 2 + 1 = 5
b = 5
The equation is therefore;
f(x) = -2·x² + 5·x - 1.
Answer:
b

Terrance makes $12.50 per hour doing landscaping and earned $275 this
week. How many hours did he work?
Answer:
22 hours
Step-by-step explanation:
pay rate = (amount of money)/time
(pay rate) * time = amount of money
time = (amount of money)/(pay rate)
time = $275/($12.50/hour)
time = 22
Answer: 22 hours
Answer:
22 hours
Step-by-step explanation:
We know that Terrance makes $12.50 per hour and he made $275 a week. We can divide 275 by 12.50 :
275 ÷ 12.50 = 22
So Terrance worked 22 hours
Check answer:
22 x 12.50 = 275

Binomial (x - 6) and trinomial (-2x2 + x + 9) are the factors of which of the
following polynomials?
2x^3+12x-3x+54
-2x^2+15
-2x^3+13x^2+3x-54
O 2x^2-3
Answer:
Option (3)
Step-by-step explanation:
If binomial (x - 6) and trinomial (-2x² + x + 9) are the factors of a polynomial then their multiplication will be equal to the polynomial.
(x - 6)(-2x² + x + 9) = x(-2x² + x + 9) - 6(-2x² + x + 9)
= -2x³ + x² + 9x + 12x² - 6x - 54
= -2x³ + 13x² + 3x - 54
Therefore, Option (3) will be the correct option.

Step-by-step explanation:
Peter wants to buy a coat that costs $87 at full price.The coat is now on sale for 40% off
Part A: Explain how Peter can use the fact that 10% of $87 is $8.70 to find the amount he will save on the coat
Part B: Use the same method to find the amount Peter would save on a $64 coat that is on sale for 40% off
Answer:
Step-by-step explanation:
Peter can use the 10% of 80 to find 40% by multiplying the 8.7 by 4 because if 10% =8.7 then multiply 8.7 by 4 which is = 34.8 now subtract this from the total, 87-34.8= 52.2 so 40% of 87 is 52.2.
To find out b we need to find out 10% of 64, so we move the decimal which is 6.4, then multiply 6.4 by 4 which is 25.6. then subtract this from the total, 64-25.6= 38.4

46. Word problem: The distance the Green family traveled during their family vacation is given by the equation y=65x, where x represents the number of hours spent driving. How far does the Green family travel in 8 hours?
Answer: The answers are in the steps.
Step-by-step explanation:
A standard form equation says that Ax + By=C
SO we have to set all the equations to be like that.
43. y = 12x Subtract 12x from both sides.
-12x + 1y = 0 In this case -12 is A, 1 is B , and 0 is C.
44 . -4y =3x -24 subtract 3x from both sides
-3x - 4y = -24 A is -3 , B is -4, and C is -24
45. 4x = 8y - 12 Subtract 8y from both sides.
-8y -8y
4x - 8y = -12 A is 4, B is -8 and C is -12
46. If we are given the equation y=65x and x represent the number of hours spent driving. And it says that how far do you travel in 8 hours then plot 8 into the equation for x and solve for y.
y = 65(8)
y= 520
They traveled 520 miles in 8 hours .

Un terreno ha sido cultivado con tres variedades de claveles. La sexta parte ha sido sembrada por
claveles rojos, la cuarta parte por claveles amarillos y el resto por claveles blancos.
Actividad 1
1 ¿Qué parte del terreno se sembró con claveles rojos y amarillos? Utilice el espacio para hacer
el proceso.
Answer:
1) Se siembra cinco doceavas partes del terreno con claveles rojos y amarillos, 2) Se siembra siete doceavas partes del terreno con claveles blancos.
Step-by-step explanation:
El enunciado se encuentra incompleto. La pregunta faltante es:
2 ¿Qué parte del terreno corresponde a los claveles blancos?
1) Sea [tex]A[/tex] el área total sembrada con los tres tipos de claveles. Entonces, las áreas sembradas con claveles rojos y claveles amarillos son [tex]\frac{1}{6}\cdot A[/tex] y [tex]\frac{1}{4} \cdot A[/tex], respectivamente.
El área sembrada con claveles rojos y amarillos se obtiene al sumar las áreas correspondientes, es decir:
[tex]x = \frac{1}{6}\cdot A + \frac{1}{4}\cdot A[/tex]
[tex]x = \left(\frac{1}{6}+\frac{1}{4}\right)\cdot A[/tex]
[tex]x = \left(\frac{4+6}{24} \right)\cdot A[/tex]
[tex]x = \frac{10}{24}\cdot A[/tex]
[tex]x = \frac{5}{12}\cdot A[/tex]
Se siembra cinco doceavas partes del terreno con claveles rojos y amarillos.
2) El área sembrada con claveles blancos se obtiene al sustraer el área obtenida en el punto anterior del área total. Esto es:
[tex]x = A - \frac{5}{12}\cdot A[/tex]
[tex]x = \left(1-\frac{5}{12} \right)\cdot A[/tex]
[tex]x = \left(\frac{12}{12}-\frac{5}{12} \right)\cdot A[/tex]
[tex]x = \left(\frac{12-5}{12} \right)\cdot A[/tex]
[tex]x = \frac{7}{12}\cdot A[/tex]
Se siembra siete doceavas partes del terreno con claveles blancos.
