Answer 1

Answer: $( ((2)/(x) -1))/( ((1)/(x) -1))= (( (2-x)/(x)))/(( (1-x)/(x))) = (2-x)/(1-x)$ . Now the answers on your paper do not have this choice, but if you think about it, (2-x)=-1(x-2) and (1-x)=-1(x-1). This means that when you have (2-x)/(1-x), this also equals to (x-2)/(x-1), since the -1's cancel out. So, the answer is D.

I hope this was helpful!

Consider the following system of equations: y = 5x + 6
y = −x − 7

Which description best describes the solution to the system of equations?

Line y = 5x + 6 intersects line y = −x − 7.
Lines y = 5x + 6 and y = −x − 7 intersect the x-axis.
Lines y = 5x + 6 and y = −x − 7 intersect the y-axis.
Line y = 5x + 6 intersects the origin.

it says
which best describes the SOLUTION to the system of equations
the solution is the set of points that satisfies both equations, it is also the intersection

therfor the answer is the first option "Line y = 5x + 6 intersects line y = −x − 7."

Answer:

Line y = 5x + 6 intersects line y = −x − 7.

Step-by-step explanation:

Both Lines intersect both the x and the y axis.
y = 5x + 6

y = −x − 7

Write the equation of the parabola with a focus (-1 4) and directrix y = 3

Answers

parabola
4P(y-k)=(x-h)^2
where (h,k) is vertex
P is distance from vertex to focus which is also equalt to distance from vertex to directix

we plot those points and see it opens up (don't cross directix)
P is positive
from 4 to 3 is a distace of 1
1/2=1/2
P=1/2
3+1/2=3.5
the vertex is (-1,3.5)

4(1/2)(y-3.5)=(x+1)^2
2(y-3.5)=(x+1)^2

put in vertex form (solve for y)
divide both sides by 2
y-3.5=(1/2)(x+1)^2
add 3.5
y= $(1/2)(x+1)^(2)+3.5$

Erik and Nita are playing a game with numbers. In the game, they each think of a random number from zero to 20. If the difference between their two numbers is less than 10, then Erik wins. If the difference between their two numbers is greater than 10, then Nita wins. I pick Erik won and they asked,Use your previous answers to write an algebraic statement that represents all the ways your player will win. Be sure to define your variable

Answers

An algebraic statement that represents all the ways Eric will wins is $|x-y|<10$ , where $x$ be the number that Eric thinks and $y$ be the number that Nita thinks.

If the difference between their two numbers is less than $10$ , then Erik wins. If the difference between their two numbers is greater than $10$ , then Nita wins.

Let $x$ be the number that Eric thinks and $y$ be the number that Nita thinks.

For to Eric to win, the difference in the numbers should be less than $10$ .

That is, $x-y<10$ , for $x>y$ or $y-x<10$ , for $y>x$ .

Or $|x-y|<10$ .

what is the equation of y=x^3 with the transformation: vertical compression by a factor of 1/2, horizontal shift 7 units to the left, reflection across the x-axis?

Answers

Assuming the transformations are in order,
because S(x,y) = (x, 1/2y), reverse what is done to y and simplify,
y = x^3 > y = 1/2*x^3 to compress vertically,
because S(x,y) = (x-7,y), reverse what is done to x,
y = 1/2*(x+7)^3 to shift to the left,
reflection across the x-axis changes positives to negatives,
y = -1/2(x+7)^3 to reflect across the x-axis.

Apples are on sale for $1.20 a pound. Logan bought 3/4 of a pound. How much money did he spend on apples

Answers

What I did was turn ¾ in to a fraction (which is 75%) then turned it into a decimal (.75)
then I multiplied .75 by 1.20 and .9
So she spent 90 cents on apples
Hope I helped :)

$(3)/(4) * 1.20 = (3.6)/(4) = \huge{\boxed{0.9}}$
