Answer:
Final answer is x=4, y=7.
Step-by-step explanation:
Questions says to use the graph to determine the number of solutions the system has. where system of equations are x=4 and y=x+3
any equation of the form x=k is a vertical line crossing x-axis at k.
So x=4 is a vertical line crossing x-axis at 4.
y=x+3 has slope m=1 and y-intercept b=3
So it passes through point (0,3) and for slope m=1, rise 1 up then 1 right to get new point.
Then final graph is given as shown in the picture.
We can see that both lines intersect at point (4,7).
Hence final answer is x=4, y=7.
Answer:
16x² - 8x + 8
Step-by-step explanation:
f(x)=4x-1
g(x)=x²+7
g(f(x)) = g(4x-1) = (4x - 1)² + 7 = 16x² - 2*4x*1 +1² + 7= 16x² - 8x + 8
Answer:
10
Step-by-step explanation:
d = √(x2 - x1)² + (y2 - y1)²
d = √(-8 - -2)² + (9 - 1)²
d = √(-6)² + (8)²
d = √(36) + (64)
d = √100
d = 10
