320% is equal to 3 whole parts and 20% of a part. If one part is 100, then the mixed number would be 3 20/100. However, the problem says to simplify this, so it would be, 3 1/5!
Answer:
C. y = ½x + 4
Step-by-step explanation:
Equation for a line in slope-intercept form is given as y = mx + b
So, we need to find the slope (m) and the y-intercept (b) of the line given.
m = ∆y/∆x
Using two points on the line, (0, 4) and (-2, 3),
Slope (m) = (3 - 4)/(-2 - 0)
m = -1/-2
m = ½
y-intercept (b) = 4, this is where the line intercepts the y-axis.
To write the equation, substitute m = ½ and b = 4 into y = mx + b
Thus:
y = ½x + 4
Answer:
$6.05
Step-by-step explanation:
$35.56 * .17 = 6.05
x^2=4x-5
subtract 4x from both sides
x^2-4x=-5
add 5 to both sides
x^2-4x+5=0
input into quadratic formula which is x=
or
si ax^2+bx+c
so a=1
b=-4
c=5

representeds by 'i' so solution is 3i
then if other way around then wyou would do
=
and [\tex]\sqrt{-1} [/tex] is represented by i
the solution is x=3i or i (i=
)
but i is not real, it is imaginary so there are no real solution so the answer is C
