Answer:
lower left
Step-by-step explanation:
We notice that the answer choices have only the first equation changed. The equivalent of the first equation must have the same ratios of coefficients.
x-coefficient : y-coefficient : constant
= 2 : 1 : -15 . . . . . in the given equation
2 : -2 : 30 = 1 : -1 : 15 . . . upper left — not the same
-4 : -2 : -15 = 4 : 2 : 15 . . . upper right — not the same
-4 : -2 : 30 = 2 : 1 : -15 . . . lower left — same as the given equation
-4 : 1 : 30 = 4 : -1 : -30 . . . lower right — not the same
I’m sorry bc I don’t know how to solve all of them but
#5 is C
#3, the equation is y=4
#4, the equation is x=-6
Answer:
1. 
2. 
3. 
Step-by-step explanation:
1. 
I like to make it an improper fraction first.
Now take the LCM. The LCM is 20.
Now add them.
Make this into a mixed number.
That's your answer for number 1.
2. 
Do the same thing as the previous addition problem but subtract instead.
is your answer for number 2.
3. 
is your answer for number 3.
I hope this helps! Let me know if you need help or if I got anything wrong :)
Answer:
a) The distance travelled on the cycle in the first 14 seconds is 96 meters.
b) The acceleration in the first 4 seconds is 2 meters per square second.
Step-by-step explanation:
a) The distance travelled by the cycle is equal to the area below the curve, which is the sum of the first triangle and the rectangle:
The distance travelled on the cycle in the first 14 seconds is 96 meters.
b) The acceleration is represented by the slope of the line, which is determined by definition of secant line:
(1)
The acceleration in the first 4 seconds is 2 meters per square second.
Answer:
a= $10.00
Step-by-step explanation:
It's very simple. Move /8 to the other side of the equation. It should give you $1.25 x 8. Solve the multiplication and you should get $10.00.
If I didn't make my explanation clear enough, please comment. I sometimes don't even explain myself very well.
