please give me a brainliest answer
Step-by-step explanation:
just look at the graph and check the typical "special" points.
e.g. when x = 0, and when y = 0, and maybe (depending on the curve) some other interesting ones.
so, what does the graph tell for x = 0 ?
it says y = 5.
that rules out C and D, because they would deliver y = 1/5 for x = 0.
so, it can only be A or B.
now, what does the graph tell us for y = 0 ?
ok, it tells us, x = 1.
that does not help us in this case, as both, A and B deliver y = 0 for x = 1
so, let's look at another good point. good points are points, where we can see pretty precisely their coordinates on the chart, and where these coordinates are even integer numbers.
I see e.g.
x = 2, and y = -5
let's try A
-5 = -5 × cubic root(2 - 1) = -5 × cubic root (1) = -5×1 = -5
so, -5 = -5, that is correct.
let's verify by checking also B
-5 = 5 × cubic root (1 - 2) = 5 × cubic root (-1) = 5×-1 = -5
-5 = -5, again, this is correct.
hmmmmm.
when we think about it, in fact, A and B are the same function (by the way, C and D are equal to each other too).
either your teacher made a mistake or tried to trick you.
A and B are both the right answer.
why ?
A (I only write "cr" for cubic root now)
y = -5 × cr(x - 1) = 5 × -1 × cr(x - 1) = 5 × cr((-1)³(x - 1)) =
= 5 × cr(-1 × (x - 1)) = 5 × cr(x×-1 - 1×-1) = 5 × cr(1 - x) = B
so, A and B are actually equal.

give the slope perpendicular to the equation 2x-y=5
Answers
Answer:
- [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
2x - y = 5 ( subtract 2x from both sides )
- y = - 2x + 5 ( multiply through by - 1 )
y = 2x - 5 ← in slope- intercept form
with slope m = 2
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{2}[/tex]

Emma is making a snack mix of pretzels and peanuts. For every batch, she uses 2 thirds cup of peanuts and 3 u 2 , 1 half cups of pretzels. Use the ratio of pretzels to peanuts to find the constant of proportionality. Write an equation that relates the amounts of pretzels and peanuts in the snack mix.
Answers
Answer:
Explanation:
So the equation it's asking you to do is like y=kx ,
so your k is 2/3.
y=2/3x
Then for x it's 3 1/2.
y= 2/3(3 1/2)
now your "y" is any variable to hold the other too.
Hope this helped!
y= 2/3( [tex]3\frac{1}{2}[/tex]) is the equation that relates the amounts of pretzels and peanuts in the snack mix.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that Emma is making a snack mix of pretzels and peanuts
For every batch, she uses 2/3 cup of peanuts and [tex]3\frac{1}{2}[/tex] cups of pretzels
We need to find an equation that relates the amounts of pretzels and peanuts in the snack mix.
The equation will be in the form of y=kx
From the given information the value of k is 2/3
y=2/3x
y= 2/3( [tex]3\frac{1}{2}[/tex])
Hence, y= 2/3( [tex]3\frac{1}{2}[/tex]) is the equation that relates the amounts of pretzels and peanuts in the snack mix.

Find the sum. Write your answer in simplest form. 7/10 - 1/4
Answers
Answer:
9/20 or 45%
Step-by-step explanation:
If we make common denominators (for this example, we will make each denominator 20), this would make 7/10 = 14/20 and 1/4 = 5/20. From there, we subtract the numerators from each other (14-5) and leave the denominators alone. The difference comes out to 9/20 and there is no way to simplify it further, making it the final answer.
