Answer:
The equations 3·x - 6·y = 9 and x - 2·y = 3 are the same
The possible solution are the points (infinite) on the line of the graph representing the equation 3·x - 6·y = 9 or x - 2·y = 3 which is the same line
Step-by-step explanation:
The given linear equations are;
3·x - 6·y = 9...(1)
x - 2·y = 3...(2)
The solution of a system of two linear equations with two unknowns can be found graphically by plotting the two equations and finding the coordinates of the point of intersection of the line graphs
Making 'y' the subject of both equations gives;
For equation (1);
3·x - 6·y = 9
3·x - 9 = 6·y
y = x/2 - 3/2
For equation (2);
x - 2·y = 3
x - 3 = 2·y
y = x/2 - 3/2
We observe that the two equations are the same and will have an infinite number of solutions
The Nisbets went through the drive through
at the donut shop and spent $10.50 on 2
cups of coffee and 4 donuts. Behind them,
the Roys spent $8.25 on 1 cup of coffee and
5 donuts. What is the cost of one cup of
coffee?
Answer:
One cup of coffee is $3.25
Step-by-step explanation:
Create a system of equations where c is the cost of a cup of coffee and d is the cost of a donut
2c + 4d = 10.5
c + 5d = 8.25
Solve by elimination by multiplying the top equation by -5 and the bottom equation by 4
-10c - 20d = -52.5
4c + 20d = 33
Add them together and solve for c
-6c = -19.5
c = 3.25
So, a cup of coffee is $3.25
A list of 5 numbers is shown below.
0, 3, 7, -6, -12.3
Which set contains all the numbers in the list?
A integers
B whole numbers
C natural numbers
D rational number
Answer:
D. Rational Number
Step-by-step explanation:
Integers are defined as all whole numbers, positive and negative, including 0. Since in the list there is a number that is not whole, A is not the correct answer choice.Whole numbers are all positive numbers (including 0) without decimals or fractions. Since the list has a number that is not a whole number, along with two that are negative, B is also not correct.Natural numbers are all positive numbers (excluding 0) without decimals or fractions. Since there is a 0 in the list, C is not correct.Rational numbers are all numbers that can be simplified into a ratio with 2 integers (i.e. π and e are not rational). Since every number on the list can be put into this category, answer choice D is correct.find the minimum value of the parabola[tex] y = x^{2} + 3x + 2[/tex]

Quadrilateral ABCD is inscribed in a
circle.
What is the measure of angle A?
(x + 15)
Enter your answer in the box
mZA=
Answer:
<A = 133degrees
Step-by-step explanation:
Find the diagram attached
Using the theorem that "the sum of opposite angle of a cyclic quadilateral is 180 degrees, hence;
m<A + m<C = 180
4x+5 + x + 15 = 180
4x+x+5+15 = 180
5x+20 = 180
5x = 180 - 20
5x = 160
x = 160/5
x = 32degrees
Get the measure of angle A
<A = 4x+5
<A = 4(32)+5
<A = 128+5
<A = 133degrees

3/ 4 by 1/ 2 to get 3 /4 ⋅ 1/ 2 = 3/ 8
Answer:i think
Step-by-step explanation:
3/4 divided by 1/2 =1.5 or 3/4 times 1/2 = 3/8

If 2 lines intersect the system is called...
1. independent and inconsistent
2. dependent and consistent
3. independent and consistent
4. dependent and inconsistent
Answer:
3. independent and consistent
Step-by-step explanation:
Intersecting Lines have a single point at which the lines intersect. Therefore the solution to this type of system is called a consistent system. (A type of system of linear equation in two variables.) Therefore, there will be no point that is common to both lines. If a system has at least one solution, it is said to be consistent. If a consistent system has exactly one solution, it is independent. If a consistent system has an infinite number of solutions, it is dependent. When you graph the equations, both equations represent the same line.

If a letter is randomly chosen, what is the probability of choosing the letter A?
Answer:
it depends on how many letters there are to choose from.
Answer:
if its out of the alphabet, the probability of choosing A is 1/26, or 3.85%
Step-by-step explanation:
There are 26 letters in the alphabet, and only one of them is A. So, a ratio for that could be 1/26. 1/26 as a percent is 3.85%. Hope this helps!
Or if you want to be really specific, 1/26 as a percent is 3.8462%.

Find the interest on $6,000 at 5% for 8 months.
A: $200
B: $2,000
C: $240
D: $2,400
Answer:
A.$200
Step-by-step explanation:
I = PRT/ 100
P = $6000
R = 5%
T = 8 months = 8/12 = 2/3
I = (6000 × 5 × 2/3) /100
I = 20000 / 100
I = $200

If we let x denote the length of the morning walk, Ahmed walks x + 2.5x or 3.5x miles each day. At the end of the week he has walked 7 times as far and he said that this was 30 miles.
Solve the equation to find out the distance of Ahmed’s morning walk x. Explain your reasoning and verify your answer.
Answer:
x = 1.2245
Step-by-step explanation:
Ahmed walks 3.5x miles each day.
Thus, at the end of a week (7 days), he would walk;
3.5x * 7 = 24.5x miles
But he said that his walk in a week = 30 miles. So that,
24.5x miles = 30 miles
24.5x = 30
x = [tex]\frac{30}{24.5}[/tex]
= 1 [tex]\frac{11}{49}[/tex]
x = 1.2245
To verify the answer,
24.5x = 24.5(1.2245)
= 30.00

The random variable X~(30,2^2)
Find p(X<33)
Find p(X>26)
Answer:
i) P(X<33) = 0.9232
ii) P(X>26) = 0.001
Step-by-step explanation:
Step(i):-
Given that the mean of the Population = 30
Given that the standard deviation of the Population = 4
Let 'X' be the Normal distribution
Step(ii):-
i)
Given that the random variable X = 33
[tex]Z = \frac{x-mean}{S.D}[/tex]
[tex]Z = \frac{33-30}{2} = 1.5[/tex] >0
P(X<33) = P( Z<1.5)
= 1- P(Z>1.5)
= 1 - ( 0.5 - A(1.5))
= 0.5 + 0.4232
P(X<33) = 0.9232
Step(iii) :-
Given that the random variable X = 26
[tex]Z = \frac{x-mean}{S.D}[/tex]
[tex]Z = \frac{33-26}{2} = 3.5[/tex] >0
P(X>26) = P( Z>3.5)
= 0.5 - A(3.5)
= 0.5 - 0.4990
= 0.001
P(X>26) = 0.001
Y=2write the equation of the line in slope intercept form
Answer:
y = 0x + 2
Step-by-step explanation:
y = 2 is the same as y = 0x + 2. The slope of this line is zero (0) (the line is horizontal).
In slope-intercept form, the equation of this line is y = 0x + 2, which may be left as is or changed to y = 2.
