Answer:
x = 20
Explanation:
Let's solve your equation step-by-step.
−10x = −200
Step 1: Divide both sides by -10.
−10x
/−10 = −200
/−10
x = 20
Answer:
The original number is 28
Step-by-step explanation:
start by listing all possible combinations of digits that give 10 when added:
19 (1+9=10)
28 (2+8 =10)
37 (3+7=10)
46 (4+6=10)
55 (5+5=10)
Look into the order of digits reversed and what the difference with the original number gives:
1) 19 reversed is 91 then when we subtract 91 - 19 we obtain 72
2) 28 reversed is 82 hen when we subtract 82 - 28 we obtain 54 which is the combination we where trying to find.
Notice as well, that as we go down the list, the differences between reversed digit number and original become smaller (and ends being zero for the number 55), so they do not satisfy the requirement.
Therefore 28 is the answer, since 82 (the new number formed when the digits are reversed) exceeds the original number by 54.
Answer:
Step-by-step explanation:
(x + 0)/2 = 6
x + 0 = 12
x = 12
(y + 4)/2 = -7
y + 4 = -14
y = -18
(12, -18)

This equation is in a form known as "standard form." ax+by=c Standard form is commonly used, however for comparing slopes, there is a more efficient equation to use.
Point-slope form (y=mx+b) allows lines' slopes (y) and y-intercepts (b) to be quickly compared and contrasted. Let's put the equation into this form.
2x-y=-1
-2x -2x
-y = -1 - 2x
*-1 *-1
y= 1 + 2x
Switch pieces around
y= 2x + 1
The slope is 2, the y intercept is 1.
