I'm not sure I have done this in sch, but I have done very similar
Answer:
number one is 36 cm
number 4 is
Step-by-step explanation:
Plot the intercepts:
y=-1
x=?
to find the x intercept, you dont solve the equation as it is solved in the slope-intercept form. instead, you simply plug in 0 for y:
0=1/4x-4
0=1/4x-4+4
4=1/4x
4/1/4=1/4x
1/4=0.25
x=16
revise:
y=(0, -1)
x=(16,0)
graph the slope for y=-1/2x-1: start from say point (0,-1)
graph the slope for y=1/4x-4: start from say point (16,0) ; you can just ise the intercept (0,-4) since the graph is diluted small...anyways
the points intersect at (4, -3) so thats the solution to the equations
NOTE: when graphing slopes that are negative either the numerator or the denominator can be graphed negative. so I graphed the first equation with the numerator as the positive and the denominator as the negative : rise= 1 ; run: -2. once i got to the end of the provided graph i started from the -1 y-intercept again and graphed the equation using: rise=-1; run=2
*graphing messes me up, too*
Answer:
6/3
Step-by-step explanation:
our average speed can be calculated in a couple different ways
is this case lets use a weighted average of the two speeds to find the average speed.
we know that that we were only going half as fast on the way back so it would take us twice as long
so our average speed would be (1/3) * 8 + (2/3) * 4
8/3 + 8/3 = 16/3 mph
another way to look at it is
to say we covered a total distance of 4 miles (2 out and 2 back)
the first 2 miles took us 1/4 of an hour since we were going at a rate of the 8 mph
the next 2 miles took us 1/2 of an hour since we were going at a rate of 4 mph
so we covered a distance of 4 miles in a time of 3/4 of an hour
distance = speed * time
speed = distance/time
speed = 4 /(3/4)
speed = 16/3 so either way we come up with the same answer
Given : −3 + 5 + 6g = 11 − 3g
To find : The variable g
Solution:
Isolate and solve for the variable g in the equation −3 + 5 + 6g = 11 − 3g
<u>Steps:</u>
−3 + 5 + 6g = 11 − 3g
2 + 6g = 11 − 3g
6g = −3g + 9
9g = 9
g = 1
Hence,
Answer: g = 1
