No yes yes yes no ; sol. when x=4 , f(x) = 0 ,so (x-4) is right answer.....
X=45
We already know that one angles is 90 degrees and that the full degrees inside a triangle is 180
So minus 90 from 180 and you get 90.
Since the other two angles are congruent that means they have the same measure so divide 90 by 2 to get the measure of both angles which is your answer
Answer:
A. x=2, y = 7.
B. (2, 7).
Step-by-step explanation:
A. You can eliminate y by subtracting the equations:
y = 8x - 9
y = 4x - 1 Subtract:
0 = 4x - 8
4x = 8
x = 8/4 = 2.
Now substitute for x in the first equation:
y = 8(2) - 9 = 7.
Check in the second equation:
y = 4x - 1
7 = 4(2) - 1 = 7. Check is OK.
B. On the graph they will intersect at the point (2, 7).
They will intersect here because the values x=2 and y=7 satisfy both the 2 equations.
