b. 3x - y = 2
4x + 9y = 36
C. x-3y = -18
9x + 4y = 9
d. x + y = 10
9x + 4y = 13
Answers
Answer:
B
Step-by-step explanation:
slope formula
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
we have the two points
(2,4) (3,7)
[tex]\frac{7-4}{3-2}=3[/tex]
which means the slope for line m is 3x
our equation so far looks like this
y=3x+b
plug in a set of numbers to solve for b
let's use (2,4)
4=3(2)+b
4=6+b
b= -2
which means our equation is
y= 3x-2
which is equal to
2= 3x-y
the only answer is then B

Here is a right-angled triangle.
y cm
8.2 cm
12.3 cm
Work out the value of y.
Give your answer correct to 1 decimal place.
Answers
Answer:
9.1
Step-by-step explanation:
Let,
hypotenuse = 12.3 cm
perpendicular = 8.2 cm
base = y cm
(hypotenuse)^2 = (perpendicular)^2 + (base)^2
(12.3)^2 = (8.2)^2 + y^2
151.29 = 67.24 + y^2
151.29 - 67.24 = y^2
.: y^2 = 84.05
y = √84.05
y = 9.1

Given:
The inequality is
[tex]c\leq 7[/tex]
Where, c is the number of cars in the parking lot.
To find:
The graph for the given inequality.
Solution:
We have,
[tex]c\leq 7[/tex]
Here, the value of c can be any real number less than or equal to 7. But c is the number of cars, so c must be a non-zero integer.
Since, all the non-zero integer values less than or equal to 7 are included in the solution set, therefore, c = 0,1, 2,3,4, 5,6,7.
In the graph of the given inequality, there are close circles on 0,1, 2,3,4, 5,6,7 as shown in option D.
Therefore, the correct option is D.

4x – 2y = -12
Answers
Answer:
x = 14
y = 22
Step-by-step explanation:
y = x + 8
4x - 2y = -12
Solve
_____________
Since we see that the first equation has y alone, we can substitute it into the values of y in the second equation.
4x - 2(x + 8) = -12
Distribute :
4x - (2(x) + 2(8)) = -12
4x - 2x +16 = -12
Combine like terms :
2x + 16 = -12
Subtract 16 from both sides :
2x = -28
Divide 2 from both sides to get x alone :
x = 14
Now that we know what x is, substitute it in the first equation to get y :
y = (14) + 8
y = 22
Answer:
(2 , 10) or x = 2 & y = 10
Step-by-step explanation:
y = x + 8
4x – 2y = -12
1. Substitute x + 8 in for the y in the other equation.
2. Solve for x
3. Take the solution for x and substitute the number in for the x in y = x + 8.
4. Solve for y.
5. Your answer is the result.
4x - 2(x + 8) = -12 Distributive Property
4x - 2x - 16 = -12 Combine like terms
2x - 16 = -12 Isolate the x, so start by moving -16
+ 16 +16
2x + 0 = 4 Delete the 0. It is a place holder you don't need
2x = 4 Isolate the x by dividing both terms by 2.
2 2
x = 2
y = x + 8 Substitute the 2 in for x and solve the one step equation.
y = 2 + 8
y = 10

two friends have a conversation mario tells roberto "the money i have is twice that you have" roberto answer "if you give me 6 dollars will we both have the same amount" how much money have each of them?
Answers
Answer:
Before anyone gives anyone money, Mario has 24 dollars and Roberto has 12 dollars. After they give each other money, both of them have 18 dollars.
Step-by-step explanation:
Mario has twice as much as Roberto, BUT if Mario gives Roberto 6 dollars, then they have the same amount.
M = 2R
M - 6 = R + 6
To isolate M, you need to add 6 on both sides.
M - 6 + 6 = R + 6 + 6
M = R + 12
M = 2R
Substitute M for the value above that we found.
R + 12 = 2R
Now we subtract R on both sides, so that only one side has the variable R.
R - R + 12 = 2R - R
12 = R
M = 2R
Substitute for the value of R.
M = 2 x 12
M = 24
