Negative. It’s the only one that makes since. ( probably)
Answer:
C(7,-8)
R= 8
The general formula of a circle = (x-a)+(y-b)=r²
Hello! The x-intercept is where the line crosses the x-axis when y = 0. We already have the expression shown. We will plug in 0 as y to get this:
5x - 8(0) = 40.
As you probably know, anything times 0 is 0, so -8 * 0 is 0. All we have is 5x = 40. Divide each side by 5 to isolate the x. 5x/5 cancels out. 40/5 is 8. There. x = 8. The x-intercept is (8, 0).
Answer:
The number pattern is that the decimal point moves one place to the left each time.
Next three numbers: 7.3456, 0.73456, 0.073456
Step-by-step explanation:
2x^2 -5x -3 = 0
D = 25 +24 = 49
x_1,2 = (5+/- sqrt49)/4 = (5+/-7)/4 = -2/4 = -1/2 and 12/4 = 3
x_1,2 = -1/2 and 3
hope this will help you
