Use cymath it gives you the answer :)
The area is 18.
the formula to find area is Length x Width
you can make 4 1/2 4.5 to make it easier to multiply.
4.5 x 4 = 18
Answer:
94
Step-by-step explanation:
So
376= x + 3x
Where x is the hambugers and 3 x is cheeseburgers
so it is the same as
376= 4x
divide both sides by 4
x= 94
we can check by tripling x = 283 and adding the hamburgers we found to be 94 which gives us 376
The slope of any line is the inclination of the line with x axis.
For any two ordered pairs (x1,y1) and (x2,y2) the slope
m=
We need to solve for y2.
Multiplying both sides by x2-x1 we have :
y2-y1=m(x2-x1)
y1 is subtracted to y2 so we perform the opposite operation both sides
Adding y1 both sides:
y2= x(2-x1)+y1.
The third option is the right answer.
Answer:
(2,-5)
Step-by-step explanation:
See attachment
One can also solve this by calculation:
y=2x-9
y=-2x-1
-
Rearrange either equation to find x. I'll use the first:
y=2x-9
2x = y+9
x = (y+9)/2
Now use this value of x in the second equation:
y = -2x-1
y =-2((y+9)/2)-1
y = (-2y-18)/2)-1
y = -y -9 - 1
2y = -10
y = -5
Now use -5 for y in the rearranged equation:
y = -2x-1
-5 = -2x-1
-2x = -4
x = 2
Solution is (2,-5)
But the question wants a graph solution, which is also fun when you use DESMOS.
