f(x)=2
f(x) is the function, x inside represent the input, while the value the function is equal to is the output.
So to solve for x, look at where f(x)/ y is equal to 2. And, from there the function is equal to 2 when x=-1.
So your answer is x=-1

much was left in the account?
Answers
Hello :D
$40.00 x 3 = $120.00
$20.00 x 2 = $40.00
$120.00 + $40.00 = $160.00
$400.00 - $160.00 = $240.00
There is $240.00 left in the account.

-3x + 6y = 18
-3x = 6y+14
a) What is the slope of the 1st equation?
b) What is the slope of the 2nd equation?
c) Are they parallel, perpendicular, or neither?
Answers
Step-by-step explanation:
-3x + 6y = 18
-3x = 6y+14
a) the slope of the 1st equation = -(-3)/6 = ½
b) the slope of the 1st equation = -3/6 = -½
c) they are niether parallel nor perpendicular
Answer:
a) ¹/₂
b) -¹/₂
c) neither
Step-by-step explanation:
Slope-intercept form of a linear equation:
[tex]y=mx+b[/tex]
where:
m is the slopeb is the y-interceptGiven equations:
[tex]\begin{cases}-3x+6y=18\\-3x=6y+14 \end{cases}[/tex]
To find the slopes of the given equations, rearrange them to make y the subject then compare with the slope-intercept formula:
Equation 1
[tex]\begin{aligned}-3x+6y & = 18\\6y & = 3x + 18\\y & = \dfrac{3x+18}{6}\\\implies y & = \dfrac{1}{2}x+3\end{aligned}[/tex]
Therefore, the slope of Equation 1 is ¹/₂.
Equation 2
[tex]\begin{aligned}-3x & = 6y+14\\6y & = -3x-14\\y & = \dfrac{-3x-14}{6}\\\implies y& = -\dfrac{1}{2}x-\dfrac{14}{6}\end{aligned}[/tex]
Therefore, the slope of Equation 2 is -¹/₂.
Parallel slopes have the same slope.
Perpendicular slopes are at right angles to each other and therefore the product of their slopes is -1 (negative reciprocals of each other).
Therefore, the slopes of Equation 1 and Equation 2 are neither parallel or perpendicular.

A motorboat travels 448 kilometers in 8 hours going upstream and 440 kilometers in 5 hours going downstream. What is the rate of the boat in still water and what is the rate of the current?
Answers
9514 1404 393
Answer:
boat: 72 km/hcurrent: 16 km/hStep-by-step explanation:
The speed difference between boat and current is the upstream rate:
(448 km)/(8 h) = 56 km/h
The sum of speeds of boat and current is the downstream rate:
(440 km)/(5 h) = 88 km/h
The rate of the boat is half the sum of these:
(56 +88)/2 = 72 . . . km/h
The rate of the current is half their difference:
(88 -56)/2 = 16 . . . km/h
The rate of the boat is 72 km/h; the rate of the current is 16 km/h.

What factors of 25 have the sum of -24
Answers
Answer:
Factors of 25 are the numbers, which gives the result as 25 when multiplied together in pair of two. When we divide a number by one of its factors, then the resultant quotient is a whole number. The factors of 25 can be represented in positive as well as in negative form, but it cannot be a decimal or fraction. Similarly, the pair factors of 25 can also be represented in positive and negative form. For example, the pair factor of 25 can be (1, 25) or (-1, -25). If we multiply a pair of negative numbers, such as multiplying -1 and -5, it will result in 25 so there is no sum that will equal to -24

if 4 is added to the numerator of the fraction 2/5, what number must be added to the denominator to make the fraction equivalent to 1/2?
Answers
Answer:
7
Step-by-step explanation:
Let X be the number...
2+4/5+X=1/2
6/5+X=1/2
12=5+X
X=7
Answer:
7
Step-by-step explanation:
By adding 4 to the numerator 2, we get 6 / 5.
Since 1 / 2 = 0.5, we need to find a number that we can divide 6 by to get 0.5.
Since 0.5 is half of a unit, we just need to find a number which it's half is 6.
6 * 2 = 12 (meaning 6 is half of 12), so 6 / 12 = 0.5 meaning 6 / 12 it's equivalent to 1 / 2.
12 - 5 = 7, so we need to add seven to the denominator to make the fractions equivalent.
