The answer is D. He divided both sides by 5 instead of dividing both sides by -5.
Answer:
Step-by-step explanation:
What is 15.41 rounded to the nearest hundredth?
Rounding to the Nearest Hundredth. Rounding decimals is very similar to rounding other numbers. If the thousandths place of a decimal is four or less, it is dropped and the hundredths place does not change. For example, rounding 0.843 to the nearest hundredth would give 0.84.
Answer:
The line passing through points (1,4) and (4,3).
The line passing through points (1,-4) and (4,-5).
Step-by-step explanation:
Since the equation is y=3x+1
If it was perpendicular, it means the slope would be the negative reciprocal.
So the slope would be -1/3
9-8/6-3=1/3 (not negative) <u>No</u>
3-4/4-1=-1/3 <u>Yes</u>
-5+4/4-1=-1/3 <u>Yes</u>
6-3/5-4= 3/1 <u>No</u>

Answer:
1a: x+3 = 5
1c: 6 = 2z
2b: x = 2
2d: 3 = z
3: the solutions make the hangars balance
Step-by-step explanation:
1. We can write the equations by listing the contents of the hangar and using an equal sign to show the balance between left side and right side. It can work well to put left side contents of the hangar on the left side of the equal sign.
A: x + 3 = 5
C: 1 + 1 + 1 + 1 + 1 + 1 = z + z simplifies to 6 = 2z
__
2. B: We can subtract 3 from both sides of the hangar (and equation) to find the value of x.
(x +3) -3 = 5 -3
x = 2 . . . . . hangar balances with 2 on the right
D: We can divide both sides of the hangar by 2, splitting the content into two equal parts. Then one of those parts can be removed from each side.
2(3) = 2(z)
3 = z . . . . . . hangar balances with 3 on the left
__
3. The found values will keep the hangar in balance when they are substituted for the corresponding variables.
A: 2 + 3 = 5
C: 1 + 1 + 1 + 1 + 1 + 1 = 3 + 3
Answer:
- absolute values
- subtract
- largest
Step-by-step explanation:
To combine integers with different signs find their <u>absolute values</u> then <u>subtract</u> the smaller absolute value from the larger one. Give the sum the sign of the number with the <u>largest</u> absolute value.
