Pls Help..... 50 points and brainliest if you answer correctly!
Answer:
5
Step-by-step explanation:
The left side is equal to:
x/(2.52-2.02) = x/0.5 = 2x
Let's simplify the numerator of the right side.
9*(31/20 - 1.05) = 9*(0.5) = 9/2
The denominator is 43/40 - 35/8 /7 = 43/40 - 5/8 = 43/40 - 25/40 = 18/40 = 9/20.
So 2x = (9/2)/(9/20) = 10
x = 5

Answer:
[tex]\frac{1}{5}[/tex]
Step-by-step explanation:
To find the scale factor of a dilation, we first find two corresponding sides. For example, the top edge of the black shape corresponds with the top edge of the purple shape. The top edge of the black shape measures 15 units while the top edge of the purple shape measures 3 units
Now, we divide the length taken from the figure by the length taken from the original shape. In this case, we divide the length of 3 by the length of 15.
3/15=[tex]\frac{1}{5}[/tex]

Write the equation of the parabola in vertex form.
vertex (3,1), point (2, - 6)
f(x) =?
Answer:
[tex]f(x)=-7(x-3)^2+1[/tex]
Step-by-step explanation:
Vertex form of a quadratic is given by:
[tex]f(x)=a(x-h)^2+k[/tex]
Where (h, k) is the vertex and a is the leading coefficient.
We are given that the vertex is (3, 1). Hence, h = 3 and k = 1. By substitution:
[tex]f(x)=a(x-3)^2+1[/tex]
We are also given a point (2, -6). This means that when x = 2, f(x) = -6. Hence:
[tex]-6=a((2)-3)^2+1[/tex]
Solve for a. Subtract:
[tex]-6=a(-1)^2+1[/tex]
Simplify:
[tex]-6=a+1[/tex]
Therefore:
[tex]a=-7[/tex]
Hence, our quadratic is:
[tex]f(x) = -7 (x-3)^2 + 1[/tex]

Describe the solution set of each of the following quadratic inequality or not
Answer:
See below
All the inequalities can be solved by making a table, but once they are simple factored quadratic expressions, we already know what interval it will have.
Step-by-step explanation:
1)
[tex]x^2+9x+14>0[/tex]
Factoring the expression, we have
[tex](x+2)(x+7)>0[/tex]
Considering that
[tex](x+2)(x+7)=0[/tex]
for [tex]x = -2[/tex] and [tex]x=-7[/tex] you can see that for
[tex](x+2)(x+7)>0[/tex]
[tex]x \not\in (-7, -2)[/tex]
Therefore,
[tex]S = \{x\in\mathbb{R} : x<-7 \text{ or } x>-2 \}[/tex]
[tex]S = (-\infty,-7)\cup (-2,\infty)[/tex]
2)
[tex]x^2-10x+16<0[/tex]
You can factor it again.
[tex](x-2)(x-8)<0[/tex]
You can make the table to solve all the inequalities, but once we have the expression [tex]< 0[/tex], we know that
[tex]2<x<8[/tex], therefore,
[tex]S = (2, 8)[/tex]
3)
[tex]2x^2+11x+12<0[/tex]
Factoring we have
[tex](2x+3)(x+4)<0[/tex]
Find the solutions for
[tex](2x+3)(x+4)=0[/tex]
And we know that
[tex]-4<x<-\dfrac{3}{2}[/tex]
[tex]S = \left(-4,-\dfrac{3}{2}\right)[/tex]

HELP PLS
Answer:
D
Step-by-step explanation:
Find the min, Q1, median, Q3, and Max of the data given.
✔️Arrange the data in an ordered manner:
27, 33, 33, 34, 35, 37, 37, 38, 38, 40, 43, 44, 48, 52, 57
✔️Min = 27
✔️Q1 = the 4th data set = 34
✔️Median = the 8th data set = 38
✔️Q3 = 12th data set = 44
✔️Max = 57
Therefore, the box plot that has all these values represented corrected is the box plot in the last option (D).
Use quadratic regression to find the equation of the parabola going through these 3 points.
(-5,13) (0,8) (2,48)
y=[?]x^2+[?]x+[?]
Answer:
3 + 14 + 8
Step-by-step explanation:
7a=21
a=21
The equation of the parabola that goes through the three points is:
y = 3x² + 14x + 8
The points are given as:
(-5,13), (0,8), (2,48)
To find the equation of the parabola that goes through the given three points (-5,13), (0,8), and (2,48) using quadratic regression, we need to fit a quadratic equation of the form y = ax² + bx + c to these data points.
Using the three points, we can set up a system of equations:
13 = a(-5)² + b(-5) + c
8 = a(0)² + b(0) + c
48 = a(2)² + b(2) + c
Simplifying these equations, we have:
25a - 5b + c = 13
c = 8
4a + 2b + c = 48
Solving this system of equations, we find that a = 3 and b = 14, and c = 8.
Therefore, the equation of the parabola that goes through the three points is:
y = 3x² + 14x + 8

What is the measure of B?
Answer: ∠B = 82°
Step-by-step explanation:
To find the measure of B, you have to find the measure of A.
m∠143° + m∠A = 180° because they are a linear pair
m∠A + 143 = 180
Subtract both sides by 143
m∠A = 37
Since you know the measure of angle A, you can find angle B
Angle A, B, and C should add up to 180° as triangles' angles sum up to 180°.
∠B + ∠A + ∠C = 180°
Substitute
∠B + 37 + 61 = 180
∠B + 98 = 180
Subtract 98 from both sides
∠B = 82°

The asymptote of the function f(x) = 3x + 4 is y =
Answer:
Conclusion:
No vertical asymptotes. No horizontal asymptotes. No slant asymptotes.Step-by-step explanation:
Given the function
f(x) = 3x + 4
Determining the VERTICAL ASYMPTOTES
The line x = L is a vertical asymptote of the function y=3x+4 if the limit of the function (one-sided) at this point is infinite.
It means that possible points are points where the denominator equals 0 or doesn't exist.
So, find the points where the denominator equals 0 and check them.
As can be seen, there are no such points, so this function doesn't have vertical asymptotes.
Determining the HORIZONTAL ASYMPTOTES
Line y = L is a horizontal asymptote of the function y=f(x) if either [tex]\lim _{x\to \infty }\:f\left(x\right)=L[/tex] or [tex]\lim _{x\to -\infty }\:f\left(x\right)=L[/tex], and L is finite.
Calculate the limits:
[tex]\:\lim \:_{x\to \:\infty \:}\:\left(3x+4\right)=\:\infty \:[/tex]
[tex]\:\lim \:_{x\to \:-\infty \:}\:\left(3x+4\right)=\:-\infty \:[/tex]
Thus, there are no horizontal asymptotes
Determining the SLANT ASYMPTOTES
Since the degree of the numerator is not one degree greater than the denominator, then there are no slant asymptotes.
Conclusion:
No vertical asymptotes. No horizontal asymptotes. No slant asymptotes.Answer:
