Graph the solution for the following system of inequalities. Click on the graph until the correct solution is displayed. 2x + y < 0 y ≥ -4 - 2x
Answers
The graph for these inequalities intersects at point (0,0).
The graph displays the solution to the system of inequalities: 2x + y < 0 and y ≥ -4 - 2x. Here's a breakdown:
First Inequality (2x + y < 0):
This translates to a blue line with a negative slope. Points like (0, -2) and (3, -6) lie on this line.
We shade the region below this line because the inequality specifies "less than." Points there, like (1, -5), satisfy the inequality.
Second Inequality (y ≥ -4 - 2x):
This translates to a green line with a negative slope as well. Points like (0, -4) and (2, -8) lie on the line.
Unlike the first, we shade the region above this line because the inequality specifies "greater than or equal to." Points like (1, -3), above the line, satisfy the inequality.
Combined Solution:
The solution space is the overlap where both inequalities hold true. This is the triangular region shaded in both blue and green. Points within this region, like (1, -5), satisfy both inequalities.
Checking Points:
If unsure about shading, test points outside the shaded region. For example, point (0, 0) lies above both lines, satisfying both inequalities. This confirms the shading is correct.

Which comparison is correct for the values of f(x) and g(x) when x=−1 ?
Function A: f(x)= −x^2+1
Function B:
f(−1)>g(−1)
f(−1)=g(−1)
f(−1)
Answers
Answer:
[tex]f(-1)>g(-1)[/tex]
Step-by-step explanation:
we are given
[tex]f(x)=-x^2+1[/tex]
We can plug x=-1 and find f(x)
we get
[tex]f(-1)=-(-1)^2+1[/tex]
[tex]f(-1)=-1+1[/tex]
[tex]f(-1)=0[/tex]
now, we can find g(-1)
we can look at the table and find g(-1)
so, we get
[tex]g(-1)=-4[/tex]
we know that
-4 is less than 0
so,
[tex]g(-1)<f(-1)[/tex]
or we get
[tex]f(-1)>g(-1)[/tex]

A study found that 3939% of the assisted reproductive technology (art) cycles resulted in pregnancies. twenty-fourfour percent of the art pregnancies resulted in multiple births. (a) find the probability that a random selected art cycle resulted in a pregnancy and produced a multiple birth. (b) find the probability that a randomly selected art cycle that resulted in a pregnancy did not produce a multiple birth. (c) would it be unusual for a randomly selected art cycle to result in a pregnancy and produce a multiple birth? explain
Answers
P(A and B) = P(A).P(B│A)
Look for P(A) and P(B│A).
P(A) = 39/100 = 0.39
P(B│A) =24/100 = 0.24
The probability that a randomly selected ART cycle resulted in a pregnancy and produced a multiple birth is P(A and B) is:
P(A and B) = P(A). P(B│A)
= 0.39 * 0.24
= 0.0936
(b) Let B ’ - the complement of B. This means that this is the probability that a randomly selected ART cycle that resulted in a pregnancy did not make a multiple birth is P(B’│A).
Determine P(B’│A) using the formula the complement of an event, P(E’) = 1 – P(E), where E is an event and E’ is its complement. Recall that P(B│A) = 0.24.
P(B’│A) = 1 – P(B│A)
= 1 – 0.24
= 0.76
(c) Knowing that P(A and B) = 0.0936. An event that happens with a probability of 0.05 or less is normally considered unusual. Use this information to know whether it would be unusual for a randomly selected ART cycle to result in a pregnancy and produce a multiple birth.
0.0936;
0.2964; and
no.
Explanation:
39% of ART cycles result in pregnancy. Of those, 24% result in multiple births. To find the probability that a random ART cycle results in a pregnancy with multiple births, we want to find 24% of 39%; this means we multiply these:
0.24(0.39) = 0.0936.
To find the probability that it will not result in multiple births, we subtract from 100%; since 24% of the pregnancies are multiple births, 100-24 = 76% will not be multiple births.
Now we find 76% of 39%; we multiply again: 0.76(0.39) = 0.2964.
In statistics, a result is considered unusual if the probability is 0.05 or less. Our probability was 0.0936, which is greater than 0.05; thus it is not unusual.

What is the minimum value of the parabola y= x^2+5x
Answers
The minimum value of the parabola y = x^2 + 5x is -25/4.
Explanation:The minimum value of the parabola y = x^2 + 5x can be found by completing the square.
Rewrite the equation as y = (x^2 + 5x + 25/4) - 25/4, which is equivalent to y = (x + 5/2)^2 - 25/4.
Since the square of a real number is always non-negative, the minimum value of the parabola is -25/4.

In the standard equation for a circle centered at any point, a change in the value of the number that is part of the x-term results in a vertical movement ? True or false?
Answers
Answer:
It is False as Changing value of x coordinate results in horizontal movement not in vertical moment.
Step-by-step explanation:
Standard form of circle is given by,
[tex](x-h)^2+(y-k)^2=r^2[/tex]
where, ( h, k ) = Coordinates of circle and r is radius of circle.
here h is part of x- term.
So, if change value of h to p keeping k and r constant. The coordinate of center shifted in horizontal line whose equation is y = k.
Therefor, It is False as Changing value of x coordinate results in horizontal movement not in vertical moment.

A company that sells prefabricated homes ships the frames for each home in large shipping containers. Each shipping container is in the shape of a rectangular prism and its volume can be represented by the polynomial expression 5x3 + 7.5x2, where x is the width of the shipping container.
If the length of the shipping container is five times the width, write the expression that represents the height of the shipping container in terms of its width, x.
Answers
x--------------> is the width of the shipping container
h-------------> is the height of the shipping container
l--------------> is the length of the shipping container
V------------> volume rectangular prism containers
we know that
V=x*h*l
l=5*x
and
V=5x³ + 7.5x²
then
clearing the variable h
h=V/[x*l]---------> h=[5x³ + 7.5x²]/[x*(5*x)]--------> h=[5x³ + 7.5x²]/[5*x²)]
h=(x²/x²)*[5x + 7.5]/[5]--------> h=(5x/5)+(7.5/5)------> h=x+1.5
the answer is h=(x+1.5)
Answer:
h = x + 1.5
Step-by-step explanation:
Start with the width. The width = x
The length is 5 times the width = 5*x or 5x
The volume of this is
Two things V = 5x^3 + 7.5x^2V = l * w * h Substitute the length and width into the raw formula5x^3 + 7.5x^2 = 5x * x * h
5x^3 + 7.5x^2 = 5x^2 * h Divide both sides by 5x^2
5x^3 / 5x^2 + 7.5x^2 / 5x^2 = 5x^2*h/ 5x^2
x + 1.5 = h <<<< Answer

Answer with Step-by-step explanation:
Michelle is having a poster printed from a picture that is 4 inches wide by 6 inches tall.
The enlarged poster is 20 inches wide and 30 inches tall.
20=4×5
i.e. width of enlarged picture=5×width of actual picture
30=6×5
i.e. height of enlarged picture=5×height of actual picture
Hence, proportion that can be used to represent the picture sizes is:
picture:enlarged picture = 1:5
