For the 1st equation,
2x + y = 20Putting x = 9, y = 2or, 2 (9) + 2 = 20or, 18 + 2 = 20or, LHS = RHSNow, putting x = 12, y = -4 in the above equation, we have2(12) + (-4) = 20or, 24 - 4 = 20or, LHS = RHS.So we can see that the first equation is the equation of the line.This is given in the graph in the picture.Like this way, if we check with other equations, we see that they are not the required equation of the line.Answer:
A. 2x + y = 20

what is 18/15 in lowest terms
Answer:
Find the GCD (or HCF) of numerator and denominator. GCD of 18 and 15 is 3.
18 ÷ 315 ÷ 3.
Reduced fraction: 65. Therefore, 18/15 simplified to lowest terms is 6/5.
The quadrilaterals JKLM and PQRS are similar.
Find the length x of RS.
Will mark brainliest!
The measure of side x equivalent to RS is 42
Similar shapes are shapes that have both their sides and angles to be equal.
Since both quadrilaterals JKLM and PQRS are similar, we will take the ratio of the sides as shown;
4/24 = 7/x
1/6 = 7/x
Cross multiply
x = 42
Hence the measure of side x equivalent to RS is 42

Daniel is going to buy a pizza.
He can choose one pizza variety, one extra topping and one pizza size.
He can choose from
23 different pizza varieties
18 different extra toppings
The total number of ways Daniel can choose the pizza variety, the one extra topping and the
pizza size is 3726
Work out the number of different pizza sizes that Daniel can choose from.
Answer:
9
Step-by-step explanation:
For each pizza variety, Daniel can choose 18 different toppings. Therefore, for 23 pizza varieties, Daniel can choose from 23 * 18 = 414 different combinations of varieties and toppings.
For each pizza size, Daniel can choose from 414 different combinations of varieties and toppings. Therefore, for n pizza sizes, Daniel can choose from n * 414 = 3726 combinations
414n = 3726
divide both sides by 414 to isolate the n
n = 9
Owen is driving to a concert and needs to pay for parking. There is an automatic fee of $12 just to enter the parking lot, and when he leaves the lot, he will have to pay an additional $3 for every hour he had his car in the lot.

−4x + 3y =7
5x − 2y =35
What is the solution?
Answer: x = 39/10 y = 29/5
Answer:
(17,25)
Step-by-step explanation:
To find the solution to the system, solve with elimination.
Equation 1.
−4x + 3y =7
Equation 2.
5x − 2y =35
To cancel out the y-variable, multiply the first equation by 2, and the second equation by 3.
2(−4x + 3y =7)
-8x+6y=14
3(5x − 2y =35)
15x-6y=105
Combine both equations.
-8x+6y=14
15x-6y=105
7x=119
x= 17
Plug in x into the first equation to solve for y.
-8x+6y=14
-8(17)+6y=14
-136+6y=14
6y=150
y=25

Find the slope of the line that contains (−5,4) and (2,4).
If the slope is not an integer, enter it is a fraction in simplest form. Do not enter a mixed number. Remember, a fraction in simplest form never contains a negative sign in the denominator. If the slope is undefined, “undefined” should be entered.
Answer:its a zero slope or you can do x2-x1 and y2-y1 and if its an even fraction try simplifying it .
Step-by-step explanation:
The slope of the coordinates is 0.
what is slope?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane. Calculating the slope of a line is similar to finding the slope between two different points. In general, to find the slope of a line, we need to have the values of any two different coordinates on the line.
So, Slope = m = tan θ
slope = (y2 - y1)/(x2 - x1)
given coordinates:
(−5,4) and (2,4)
So, slope = (y2 - y1)/ (x2 - x1)
slope = (4- 4)/ (2 - (-5))
slope = 0 / 7
slope = 0
Hence, the slope of the coordinates is 0.

fill in the blanks
Answer:
Step-by-step explanation:
First, to solve the problem, you must distribute the 5 to the (2 + 9). Which ends you up with 10 + 45. Which would give you 55, but we aren't solving it.
So instead, when you are distributing, you are taking the number next to the parentheses (5) and multiplying it into the parentheses like this:
(5 x 2) + (5 + 9).
That is your answer. Hope this helps.
