So, first your going to have to put it in y=mx+b
2x-2y=14
-2x -2x
-2y=-2x+14
now divide everything by -2
y=1x-7
and then do the same to the other equation.
x-y=2
-x. -x
-y=-x+2
now divide everything by -1
y=x-2
Then you just graph it. You plot the y-intercept on the y axis. and then I this case go up one over one and your get the points for each player equation.
y=1x-7. y- intercept:-7. slope:1 over 1
y=x-2. y-intercept:-2. slope:1 over 1
Answer:
ABC= 60 XYZ=540
Step-by-step explanation:
The area of a triangle is 1/2*base*height so for ABC we need to find the height first. To do this we use pythag theorem, and create the equation 13^2=5^2+height^2 rearranging this we can figure out that sqrt(height)=13^2-5^2. For the base we do 2*5 since there are two congruent line segments both equal to 5. Using this we can do 1/2*12*10=area of ABC
For XYZ we can do 1/2*30*36=area of XYZ, we can do 2*15 since there are 2 congruent 15 length line segments at the base.
Just plug in a = 5, y = -3 in that!
2a + ay = 2(5) + 5(-3) = 10 -15 = -5
thats it!
Answer:
The box contains 20 milk chocolates.
Step-by-step explanation:
Given that the chocolate box has milk chocolates and dark chocolates in a ratio of 2 milk chocolates for every 3 dark, and the total number of chocolates in the box is 50 units, to determine how many milk chocolates are in the box. it is necessary to perform the following calculation:
50 / (2 + 3)
50/5
10
Milk chocolates: 2 x 10 = 20
Dark chocolates: 3 x 10 = 30
Therefore, the box contains 20 milk chocolates.
Answer: Perimeter 210
Exclamation: I’m pretty sure you just have to multiply all the sides together
Hope this helps :3
