Answer:
Step-by-step explanation:6x+12-2 if x=1/2
13 because if the height is 14 you would subtract 28 because there’s two sides. Then you would get 26, divide that by 2 and get 13 for the base. Idk if it makes sense
Move the 1st equation to get y by itself so it’s now y=-4x so you can substitute that in for the second equation 2y+x=-7 becomes 2(-4x)+x=-7
-8x+x=-7
-7x=-7
x=1
then plug that back in to find y
4(1)+y=0
4+y=0
y=-4
now you have x and y so your coordinate (the answer) is (1, -4) hope this helps!
Answer:
The larger number is 60
The smaller number is 14
Explanation:
Assume that the larger number is x and that the smaller number id y.
We are given that:
1- The sum of the two numbers is 74. This means that:
x + y = 74
This equation can be rewritten as:
x = 74 - y .............> I
2- Four times the smaller number (4y) subtracted from the larger number (x), the result would be 4. This means that:
x - 4y = 4 ..............> II
Substitute with I in II and solve for y as follows:
x - 4y = 4
74 - y - 4y = 4
74 - 5y = 4
5y = 70
y = 70/5
y = 14
Substitute with the value of y in equation I to get x as follows:
x = 74 - y
x = 74 - 14
x = 60
Hope this helps :)
