Answer:
A. 2x - (4x + 3) = 12
Step-by-step explanation:
A. 2x - (4x + 3) = 12
B. -4(4y+)+y=3
C. 2 (4x+3) - y
D. -4x+4 x-3=3
Given equation:
-4x+y = 3. (1)
2x - y = 12. (2)
From (1)
y = 3 + 4x
Substitute y = 3 + 4x into (2)
2x - y = 12 (2)
2x - (3 + 4x) = 12
Or
2x - (4x + 3) = 12
2x - 4x - 3 = 12
- 2x = 12 + 3
- 2x = 15
x = 15/-2
x = -7.5
Substitute x = -7.5 into (1)
-4x+y = 3 (1)
-4(-7.5) + y = 3
30 + y = 3
y = 3 - 30
y = -27
36 ft
Step-by-step explanation:
Since there is a right angle been formed, you will minus 90 from 40 = 50. Then you will add it to 46 = 96.
Since there is another right angle been formed you will also subtract 90 from 30 = 60.
Then to find the distance from the cat to the fireman you will subtract 96 from 60 =36.
Therefore your answer is 36 ft
Answer:
False
Reasoning:
- It's an acute angle, 140 is obtuse
- Angles 6 and 8 are 140 degrees, so 5 can't be
Answer:
5
Step-by-step explanation:
2x + 3y = 12
2x - 2y = 2 // subtract second equation from first
5y = 10
y = 2
x = (2 + 2y) / 2 = y + 1 = 3
x + y = 5
The inference that can be made about the results is that; energy drinks enhances performance during 100 meters race.
<h3>
How to find inference from a given data?</h3>
From the given table and histogram, we can see that;
Group 1 average race time = 10.8
Group 2 average race time = 11.6
Thus, since group 1 drank energy drink and had faster times than group 2 without energy drinks, the inference that can be made about the results is that energy drinks has enhancing performance during 100 meters race.
