Answer:
7
Step-by-step explanation:
Answer:
A:40%
B:7.8
Step-by-step explanation:
Using a proportion , you can solve for the bottom side.
13/19.5 = 5.2/x
multiply 19.5 and 5.2 and rewrite the equation
101.4=13x
x=7.8
To find the scale, divide 5.2 by 13
5.2/13=0.4
Double check by dividing 7.8 by 19.5
7.8/19.5=0.4
0.4=40%
Slope-Intercept form is y=2x+2 because it takes 2 x's to move before 1 Y moves. and +2 because it is 2 places up on the Y intercept
Answer:
Step-by-step explanation:
The discriminant of a quadratic equation is b² - 4ac.
Here, a = 1, b = 3 and c = 8, and so the value of the discriminant is:
3² - 4(1)(8) = 9 - 32 = -23
The discriminant is -23 in this case.
A negative discriminant indicates that the roots will be complex.
