Answer:
x = 7/3
y = 1/3
Step-by-step explanation:
y = x - 2.... (1)
2x + y = 5.... (2)
Rearranging equation (2), we have
y = -2x +5 .... (3)
Let's multiply equation (1) by 2 so that we can easily simplify by substitution.
Therefore, it becomes 2y = 2x - 4 ... (4)
We add equation (3) and (4)
3y = 1
y= 1/3
Now, substitute (y= 1/3) in equation 1
It becomes:
1/3 = x - 2
x = 1/3 + 2
Simplifying with a LCM of 3
x = (1 plus 6, all over 3)
= 1+6/ 3
= 7/3
Answer:

Step-by-step explanation:

Total area =2triangles+3rctangles
rectangles is small ok so
we can consider the 3 rectangles as 1 big reectangle with base 5+12+13=30 and height 8
area=30*8=240
the 2 triangles
the height is 5 becasue it has to to match with the 5 on the small rectangle
base is 12
2 of them
aera=2*1/2*12*5=60
so total
240+60=300
total surfacea area is 300 in^2
Answer:
47
Step-by-step explanation:
first of all simply the ones with powers and you will get 156-9*5-64 then multiply and you will get 156-45-64 simplify and the answer is 47
Answer:
The answer to your question is y = -2x - 2
Step-by-step explanation:
Data
Point = (-4, 6)
slope = m = -2
Process
1.- Substitute the values in the formula point-slope
y - y1 = m(x - x1)
y - 6 = -2(x + 4)
2.- Simplify
y - 6 = -2x - 8
y = -2x - 8 + 6
3.- Result
y = -2x - 2 slope = -2
y-coordinate = -2
