Answer:
Although im also doing this assignment im pretty sure it means that you can get multiple solutions depending on how you solve it for example 4x4+6 you are able to get 2 answers from this.
Step-by-step explanation:
Write the equation in point-slope form of the line that passes through the given point and has the given slope: (-2, -1); m=-3
Answer:
y+1=-3(x+2)
Step-by-step explanation:
point-slope form is the formula y-y1=m(x-x1), where (x1, y1) is a point and m is the slope
we are given a point (-2, -1) and a slope of -3
all we really need to do is substitute the given into the formula
remember: since the formula gives subtraction, we're going to be subtracting, even though we have negative numbers
substitute -2 as x, -1 as y and -3 as m
y--1=-3(x--2)
we can simplify this equation:
y+1=-3(x+2)

Jonas received a gift card of $35.00 to use for an online App Market to buy applications for his tablet. All Apps cost $1.75. Which table represents the relationship between x, the number of Apps Jonas can buy, and y, the balance remaining on his gift card.
Answer:
A)
Step-by-step explanation:
The starting balance is $35
after one game purchase, the balance is 35-1.75=33.25
after two game purchases, the balance is 35-(1.75*2)=31.50

The solutions of the of the equation are,
⇒ x = 3.12
⇒ x = 0.21
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The expression is,
⇒ (3x - 5)² = 19
Now,
We can simplify the expression for the solutions as;
⇒ (3x - 5)² = 19
Take square root both side,
⇒ √(3x - 5)² = √19
⇒ (3x - 5) = √19
Add 5 both side,
⇒ 3x - 5 + 5 = √19 + 5
⇒ 3x = √19 + 5
⇒ 3x = ± 4.36 + 5
⇒ 3x = 4.56 + 5
⇒ 3x = 9.36
Divide by 3;
⇒ x = 9.36 / 3
⇒ x = 3.12
And, 3x = - 4.56 + 5
3x = 0.64
x = 0.64/3
x = 0.21
Thus, The solutions of the of the equation are,
⇒ x = 3.12
⇒ x = 0.21

An arborist examined trees in an orchard to see if they were infected with a virus. The arborist counted 7 infected trees and 43 healthy trees. What percentage of the trees in the orchard were infected?
Answer: Percentage of infected trees =2%
Step-by-step explanation:
Number of Infected trees =7
Number of healthy trees=43
Total number of trees in the orchard=43+7=50
Percentage of infected trees =Number of Infected trees/Total number of tress in the orchard x 100
7/50 x 100 =2%

All dimensions of a cylinder are multiplied by 1.5. Which statement is true?
A. The total surface area is multiplied by 3.375.
The volume is multiplied by 2.25.
B. The total surface area is multiplied by 2.25.
The volume is multiplied by 3.375.
C. The total surface area is multiplied by 3.
The volume is multiplied by 4.5.
D. The total surface area is multiplied by 4.5.
The volume is multiplied by 3.
Answer:
The true statement is;
B. The total surface area is multiplied by 2.25
The volume is multiplied by 3.375
Step-by-step explanation:
By scale drawing proportionality, we have;
The amount by which all the dimensions of the cylinder are multiplied to create an image of the cylinder = 1.5
∴ The scale factor between the original cylinder and the image of the cylinder, S.F. = 1.5
By rule, we have;
The area factor of the surface area = S.F.² = 1.5² = 2.25
Therefore;
The total surface area of the original cylinder is multiplied by 2.25 to get the total surface area of the image of the cylinder
By rule, we have;
The volume factor = S.F.³ = 1.5³ = 3.375
Therefore;
The volume of the original cylinder is multiplied by 3.375 to find the volume of the image of the cylinder.

Answer:
a. east
b. 60 feet per second
Step-by-step explanation:
did this a while ago.
a. -180 is east, 120 is east. the car is traveling east because it is moving positive. read the last sentence of the description.
b. to calculate velocity you do time times position. in this case position is 60 and time is 1 so 60*1 is 60. so it is 60 feet per second.

What is the angel of c??
Last month, he sold 50 chickens and 30 ducks for $550. This month, he sold 44 chickens and 36 ducks for $532
Answer:
★ Given :
Cost of 50 chickens and 30 ducks = $ 550
Cost of 44 chickens and 36 ducks = $ 532
★ To find :
Cost of chicken and duck
★ Solution :
Assume :
Cost of chicken = x
Cost of duck = y
According to question :
50x + 30y = 550 ......(1)
44x + 36y = 532......(2)
1) - (2)
(50x + 30y) - (44x + 36y) = 550 - 532
50x + 30y - 44x - 36y = 18
6x - 6y = 18
6(x - y) = 18
x - y = 18/6
→ x - y = 3 ....(3)
In equation 1 ,
50 x + 30y = 550
taking 10 common
10(5x + 3y) = 550
5x + 3y = 550/10
5x + 3y = 55
by taking 3 common
3(5/3 x + y) = 55
by dividing 3 on both sides
5/3x + y = 55/3 .....(4)
(3) + (4)
x - y + 5/3 x + y = 3 + 55/3
x + 5/3 x = 64/3
8/3 x = 64/3
by multiplying 3 on both sides
8x = 64
x = 64/8
→ x = 8
→ Cost of chicken = $ 8 ..
by putting value of x in equation 3
x - y = 3
8 - y = 3
y = 8 - 3
→ y = 5
→ Cost of ducks = $5..

What are the domain and the range of this function?
•< •≤ •-5 •-4 •1 •7
D: ?, ? | X: ?, ?
R: ?, ? | Y: ?, ?
Answer:
The domain is the set of x -coordinates, {0,1,2} , and the range is the set of y -coordinates, {7,8,9,10} . Note that the domain elements 1 and 2 are associated with more than one range elements, so this is not a function.

Each envelope in the class contains the same number of triangles and quadrilaterals. Write an expression that
represents the total number of sides in the room.
Answer: 3t+4q.
Step-by-step explanation: Triangles have 3 sides, so there will be 3 sides for each triangle in the envelope. This is represented by 3t. Quadrilaterals have 4 sides, so there will be 4 sides for each quadrilateral in the envelope. This is represented by 4q. The total number of sides will be the number of triangle sides and the number of quadrilateral sides together.
