Answer:
-27.51
Step-by-step explanation:
subtract the two numbers
Answer:
Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis.
Step-by-step explanation:
The range is the set of possible output values, which are shown on the y-axis.
Answer:
The answer is option 1.
Step-by-step explanation:
In order to find the equation, you have to apply Discriminant Law, D = b² - 4ac. When D < 0, the equation has no real roots (no x-intercept). When D = 0, it has 2 and equal roots (1 x-intercept). When D > 0, it has 2 distinct roots (2 x-intercept).
Option 1,
Option 2,
Option 3,
Option 4,
As you look at the graph, the curve does not meet x-axis so the discriminant must be less than 0.
P = paddling speed
C = speed of the current
Upstream: 6 = 4 (P - C. Downstream: 6 = 3 (P + C)
4P - 4C = 6
3P + 3C = 6
12P - 12C = 18
12P + 12C = 24
Add the equations:
24P = 42. P = 42/24 = 1.75 mph
Subtract the equations:
-24C = -6
C = 0.25 mph
Answer:
Slope-intercept form is
y = mx + b
We want to get the y by itself on one side of the equation.
0 = 18x + 6y – 2
First let's subtract 6y from both sides.
-6y = 18x – 2
Next let's divide both sides by -6.
y = (18 / -6)x - (2 / -6)
y = -3x + 1/3
...The last instructions are kind of confusing to me, but I think that is the answer you're after. :)
