Answer:
The first one is correct
Step-by-step explanation:
3(4+n)=n+18
Hello!
To solve whatever z is we have to get it by itself by using inverse operations. I will undo operations below.
m=q/z-v+v
m+v=q/z(z)
m+v+z=q
m+v+z-z=q-z
m+v=q-z
Here I will switch z to adding negative z so we can use the commutative property.
m+v= q+(-z)
m+v=-z +q
m+v-q=-z+q-q
m+v-q=z
We now have our formula for z. z=m+v-q. Hope this helps!
To solve each of the problems, I first looked for the equation that had the same slope value and then plugged in the 'x' coordinate to see if it gave me the correct 'y' coordinate.
1.)
D.) y = 5x + 4
14 = 5(2) + 4
14 = 10 + 4
14 = 13
2.)
C.) y = 1/5x - 19
-16 = 1/5 (15) - 19
-16 = (3) - 19
-16 = -16
3.) First, get 'y' by itself by subtracting 4x from both sides and dividing the whole equation by -12. To find perpendicular lines, the slope must be the opposite reciprocal of the first slope (in this case, flip the fraction to get the three on top). Add the opposite sign to the slope as your final step.
4x - 12y = 2
-4x -4x
-12y = -4x + 2
-12y / -12 = -4x / -12+ 2 / -12
y = 1/3x - 1/6
C.) y = -3x + 29
-1 = -3(10) + 29
-1 = (-30) + 29
- 1 = -1
The decimal will move to the left(making the number smaller) if multiplied by a negative integer power of 10.
