(7x - 23)° + (11x + 23)° = 180°
7x - 23° + 11x + 23° = 180°
18x = 180° / : 18
x = 10°
Answer:
1) slope 3/2, y-intercept 7/2
2y-3x=7
2) slope 1/5, y-intercept 3
5y-x=15
3) slope 1/5, y-intercept 4/5
-x+5y=4
4) slope 5/2, y-intercept 7/2
2y=5x+7
Step by step explanation:
1) 2y-3x=7
2y=3x+7
y=3/2y+7/2
2)5y-x=15
5y=x+15
y=1/5x+3
3)-x+5y=4
5y=x+4
y=1/5x+4/5
4)2y=5x+7
y=5/2x+7/2
A. -4/1=-4
And -4 is the slope
Let's see if this is better
1: Substitute 0 for x in the equation → y = f(0) = a^0 = 1
Therefore (0, 1) is a point on the graph
2: Substitute 1 for x in the equation → y = f(1) = a^1 = a
Therefore (1, a) is a point on the graph
3: y = f(x) = a^x is an exponential function which has a horizontal asymptote of y = 0 (equation for the x - axis) ... The reason it is above the x-axis is because there is no negative coefficient on "a" to reflect it below the x-axis
