Answer:
x = 1 , y = 4
Step-by-step explanation:
I am assuming you're looking for what x and y are? If so, then we know that
DC and AB equal each other, so
4x + y = 8
CB and AD equal each other, so
2x + y = 6
We have two equations that cannot be solved on their own, so we must solve them as a system of equations. One process to solve is elimination.
4x + y = 8
2x + y = 6
we can multiply the second equation all by -1 to make the y's cancel out and give us x. so,
4x + y = 8
-1(2x + y) = 6
4x + y = 8
-2x -y = -6
now solve them vertically. we get:
2x = 2
and so x = 1.
Now that we found x, we must find y. Using any of the two equations froom above, we can substitue our x value of 1 into it to find y. I will use the first one.
4x + y = 8
4(1) + y = 8
4 + y = 8
y = 8 - 4
y = 4
so our x is 1 and y is 4.
hope this helps! (:

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.
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.

Step-by-step explanation:
Use the slope-intercept form to graph the equation y = -4/3 x + 1
Answer:
the y intercept is 1 so you plot (0,1) on the graph, then you take -4/3 and go up 4 from the y intercept and over the left 3 times. Finally you go back to the y intercept and got down 4 and to the right 3 time then connect it with a line with arrows on both ends. hope this helps!

give the slope perpendicular to the equation 2x-y=5
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]

5x^2-9 when x = -2
5(-2)^2-9
I know the answer is 11, but how? When I did it, I got -29 and I don’t know how to get 11. Could someone explain step by step on how to get the correct answer?
5(-2)² - 9
First, solve the one in the bracket which is -2 × -2 which gives us =4
5(4) - 9
Then, multiply 5 with 4 so
20 - 9
Then you'll get 11

Algebra one please help
Answer: a
Step-by-step explanation: In the picture
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.

Find the sum. Write your answer in simplest form. 7/10 - 1/4
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.
