Answer:
D
Step-by-step explanation:
We put 2nd equation into 1st equation and get y:
We can't seem to come to a solution.
Also let's rearrange the 2nd equation into y = something form:
x = 7y + 1
7y = x - 1
y = 1/7 x -1
As we can see BOTH the lines have the same SLOPE, the number before x, which is 1/7 and we know that lines with same slope are parallel, they never intersect.
Having a solution to a system means their intersection point, since they are parallel lines, they don't intersect, and hence DO NOT HAVE A SOLUTION.
D is the correct choice.
Answer:
or 9.6×10^8
Step-by-step explanation:
The answer is written above.
Hope this helps!
First, 90 minutes will equal 1.5 hours. And I have the formula for this is distance=time×speed, so I just take 25 divided 1.5 to get the speed she is riding which equal 16 2/3 miles per hour. Hope it help!
Answer:
m<A = 69°
m<C = 69°
Step-by-step explanation:
From the question given above, the following data were obtained:
AB = AC
m<B = 42°
m<A =?
m<C =?
Since:
AB = AC
Therefore,
m<A = m<C
A + B + C = 180 (sum of angles in a triangle)
C + 42 + C = 180
Collect like terms
C + C = 180 – 42
2C = 138
Divide both side by 2
C = 138 / 2
C = 69°
Finally, we shall determine m<A. This can be obtained as follow:
m<A = m<C
m<C = 69°
Therefore,
m<A = 69°
Answer:
The slope of g(x) is less than the slope of f(x)
Step-by-step explanation:
Find the slopes of both lines with rise/run
f(x): 3/1 = 3
g(x): 2/4 = 1/2
The slope of g(x) is less than the slope of f(x)
