Answer:
Step-by-step explanation:
Let the numbers be x and y. Then we got following equations:
- x + y = 34
- 1/2x + 1/3y = 14
<u>Double the second equation and subtract from the first one. Solve for y:</u>
- x + y - x - 2/3y = 34 - 2*14
- 1/3y = 6
- y = 3*6
- y = 18
<u>Find x:</u>
Answer: x=-3
Step-by-step explanation:
5(x−8)=−55
x-8=-55/5
x-8=-11
x=-11+8
x=-3
Answer:
y = -35
Step-by-step explanation:
y=7 * -5
7 *-5 = -35
y = -35
Answer:
(3) x ≥ -3
(4) 2.5 gallons
(4) -12x + 36
Step-by-step explanation:
<em>Hey there!</em>
1)
Well its a solid dot meaning it will be equal to.
So we can cross out 1 and 2.
And it's going to the right meaning x is greater than or equal to -3.
(3) x ≥ -3
2)
Well if each milk container has 1 quart then there is 10 quarts.
And there is 4 quarts in a gallon, meaning there is 2.5 gallons of milk.
(4) 2.5 gallons
4)
16 - 4(3x - 5)
16 - 12x + 20
-12x + 36
(4) -12x + 36
<em>Hope this helps :)</em>
Hi there! So you have -3 and -1 as the x coordinates. Just forget about the negatives and make them positive. The answer will be the same. So 3-1 because difference means subtract. 2. 2 is the x coordinate. Same with the y coordinate. Drop the negative. 2-2=0. So your y coordinate is 0. So the final answer is (2,0). Let me know if you still don't understand :)
