Find the x- and y-intercepts of the equation.
4x − 2y = 2
(A) (1/2,0). (0,1)
(B). (2, 0), (0, −1)
(C). (2, 0), (0, −1)
(D). (1/2, 0), (0, −1)
Answer:
Option D
Step-by-step explanation:
Convert to slope-intercept form:
[tex]4x-2y=2[/tex]
[tex]-2y=2-4x[/tex]
[tex]y=-1+2x[/tex]
[tex]y=2x-1[/tex]
Find the x-intercept by plugging in y=0:
[tex]y=2x-1[/tex]
[tex]0=2x-1[/tex]
[tex]1=2x[/tex]
[tex]\frac{1}{2}=x[/tex]
[tex]x=\frac{1}{2}[/tex]
Therefore, the x-intercept is [tex](\frac{1}{2},0)[/tex]
Find the y-intercept by plugging in x=0:
[tex]y=2x-1[/tex]
[tex]y=2(0)-1[/tex]
[tex]y=0-1[/tex]
[tex]y=-1[/tex]
Therefore, the y-intercept is [tex](0,-1)[/tex]
So, the correct answer is option D.
Answer:
D
Step-by-step explanation:
1. To find the x intercepts, set y equal to 0 and solve for x
4x - 2y = 2
4x -2(0) = 2
4x - 0 = 2
4x = 2
x = 1/2
2. To find the y intercepts, set x equal to 0 and solve for y
4x - 2y = 2
4(0) - 2y = 2
0 - 2y = 2
-2y = 2
y = -1
2. Deon wants to find the perimeter of a square with side length 6m - 3. Write two expressions that represent the perimeter, including one expression in simplest form. Perimeter of a square- p = 4(s) or p = s + s + s + s
Step-by-step explanation:
The perimeter of the given square is: a + a + a + a = 4 a units. Hence, the formula of the perimeter of a square = 4 × (length of any one side).
The expressions that represent the perimeter of the square are p = 4(6m-3) and p = 24m - 12. And p = 24m - 12 is the simplest form of the expression.
What is perimeter?A closed shape's perimeter is the sum of the lengths of its outside boundaries. The lengths of all the sides are added to determine the measurement.
Given:
The side of the square is 6m-3 unit.
And all the sides of the squares are equal.
And the perimeter p of the square is,
= the sum of all the sides.
p = 4 x one side.
p = 4(6m-3)
The above expression represents the perimeter of the given square.
Simplifying,
p = 24m - 12
This is the simplest form of the expression.
Therefore, the required expression are p = 4(6m-3) and p = 24m - 12.

Your mother bought 2 kilograms of chicken and 3 kilograms of pork to consume in week. How many kilograms of chicken and pork did your family consume in a month?
Answer:
20?.... seems right to me.
Step-by-step explanation:
9514 1404 393
Answer:
20 kg
Step-by-step explanation:
The mass of the chicken and pork for 1 week is (2 kg) +(3 kg) = 5 kg.
Normally, we think of a month as 4 weeks.
(4 wk)(5 kg/wk) = 20 kg
If pork and chicken are consumed at the same rate for 4 weeks, the family will consume 20 kg of pork and chicken.
_____
If we consider a year to be 52 weeks (it is actually 1 or 2 days longer), then the number of weeks in an average month is ...
52/12 = 4 1/3 weeks/month
Multiplying that value by 5 kg/week will give 21 2/3 kg per month.
__
The answer depends on the assumption you make about weeks in a month.

How many ways can you make the number 2? (Using consecutive numbers)
Answer
For any two consecutive odd numbers, the difference is 2. For example, 3 and 5 are two consecutive odd numbers, their difference = 5 - 3 = 2. For any two consecutive even numbers, the difference is 2. For example, 6 and 8 are two consecutive even numbers, their difference = 8 - 6 = 2.

The total cost of 3 apples and 4 pears is £1.84
The total cost of 5 apples and 2 pears is £1.76
Work out the cost of one apple and the cost of one pear.
Answer:
an apple costs 0.24 and a pear costs 0.28
Step-by-step explanation:
3a + 4p = 1.84 3a + 4p = 1.84
-5a + 2p = 1.76 m(-2) -10a - 4p = -3.52
3a + 4p = 1.84
+ -10a - 4p = -3.52
-7a = -1.68
a = -1.68/-7
a = 0.24
3a + 4p = 1.84
3(0.24) + 4p = 1.84
0.72 + 4p = 1.84
4p = 1.84 - 0.72
4p = 1.12
p = 0.28
The cost of an apple is £0.24 and the cost of pear is £0.28
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Let a represent the cost of one apple and p represent the cost of one pear.
Then the system of equation will be;
3a + 4p = 1.84
-5a + 2p = 1.76 m(-2)
-10a - 4p = -3.52
Solving both the equation;
-7a = -1.68
a = -1.68/-7
a = 0.24
For solving p;
3a + 4p = 1.84
3(0.24) + 4p = 1.84
0.72 + 4p = 1.84
4p = 1.84 - 0.72
4p = 1.12
p = 0.28
Hence, the cost of an apple is £0.24 and the cost of pear is £0.28

Hannah drove her car 318.4km in 4h
a) Calculate her average speed=
b) At this speed, how far can she expect to travel in 5.5 h? =
Answer:
a) 79.6
b) 437.8
Step-by-step explanation:
First, you have to do 318.4/4 to find the rate she goes in the duration of an hour. The rate is 79.6, which means she travels at a rate of 79.6 kilometers per hour.
Then, you have to find the distance she takes to travel in 5.5 hours, so you have to do 5.5*79.6 which is 437.8.
So, Hannah travels 437.8 kilometers in 5.5 hours.
