Step-by-step explanation:
When multiplying and deviding, you are raising them or lowering them by a certain degree, but adding or subtractions is just combining two fractions.
Just to quickly explain the "combining" aspect, during subraction, you are combining a positive with a negative.

Find the value of x that makes lines u and v parallel, answer needed
Given:
u and v are parallel lines.
To find:
The value of x.
Solution:
If a transversal line intersect the two parallel lines, then
(1) Corresponding angles are congruent.
(2) Same sides interior angles are supplementary angles and their sum is 180 degrees.
15.
[tex]23x-2=90[/tex] (Corresponding angles)
[tex]23x=90+2[/tex]
[tex]x=\dfrac{92}{23}[/tex]
[tex]x=4[/tex]
Therefore, the value of x is 4.
16.
[tex](x+106)+(x+86)=180[/tex] (Same sided interior angles)
[tex]2x+192=180[/tex]
[tex]2x=180-192[/tex]
[tex]2x=-12[/tex]
Divide both sides by 2.
[tex]x=\dfrac{-12}{2}[/tex]
[tex]x=-6[/tex]
Therefore, the value of x is -6.
find the slope of the line
Answer:
The slope of the line is: 1
Step-by-step explanation:
Use the equation
[tex] \frac{y2 - y1}{x2 - x1} [/tex]
Use the two sets of points given to you to slve the equation.
Assign the points their variables:
x1 y1 x2 y2
(4, 4) (8, 8)
Insert the numbers into the equation:
[tex] \frac{8 - 4}{8 - 4} [/tex]
Simplify:
[tex] \frac{4}{4} = 1[/tex]
Which graph represents a geometric sequence? On a coordinate plane, 5 points are plotted. The points are (1, 1), (2, 3), (3, 5), (4, 7), (5, 9). On a coordinate plane, 4 points are plotted. The points are (1, 1), (2, 2), (3, 4), (4, 8). On a coordinate plane, 3 points are plotted. The points are (1, 2), (4, 4), (9, 6). On a coordinate plane, 3 points are plotted. The points are (1, 1), (2, 4), (3, 9).
Answer:
Graph B is the correct answer. Just in case it is not choice B for you, it's the graph with points (1,1), (2,2), (3,4), and (4,8) in that order. Sadly, the other guy is incorrect and you should not listen to him.
Step-by-step explanation:
The graph that represents a geometric sequence is (b) (1, 1), (2, 2), (3, 4), (4, 8)
What is a geometric sequence?A geometric sequence is a sequence that has a common ratio
The common ratio of a geometric sequence is calculated as:
[tex]r = \frac{y_2}{y_1}[/tex]
Using the above rule, we have:
[tex]r = \frac{2}{1} = \frac 42 = \frac 84[/tex]
[tex]r =2 =2 =2[/tex]
The above represents option B, and it has a common ratio of 2
Hence, the graph that represents a geometric sequence is (b) (1, 1), (2, 2), (3, 4), (4, 8)

180 divided by 4
Step-by-step explanation:
Kayla is thinking of a 3-digit number.
* It is divisible by 18.
* It is a palindrome (It reads the same left-to-right as it does right-to-left, like 252 and 848).
* It is one less than a multiple of 5.
What is Kayla’s number?
Answer:
kaylas thinking of the number 414
Step-by-step explanation:
414 is divisable by 18 (414 divided by 23)
414 is palindrome
414 is one less than a multiple of 5 (415)
Answer:
414
Step-by-step explanation:
The last digit must be 4 or 9 since it is one less than a multiple of five. Then, it says the number must be divisible by 18, and 18 = 2x9. Only 4 is divisible by 2, so four must be the last digit. Since it's a palindrome, the first digit must also be four. Since it also has to be divisible by nine, 4 + 4 = 8, and 8 + 1 = 9.

Consider the quadratic function, f(x)=-2x^2+12x+32=0. Select all statements that are true for the function. The value of the discriminant is -112. The value of the discriminant is 20. The value of the discriminant is 400. The function has 1 real solution. The function has 2 real solutions. The function has 2 complex solutions.
Answer:
Step-by-step explanation:
-2x² + 12x + 32 = 0
discriminant = 12² - 4(-2)(32) = 400
positive discriminant means there are two distinct real roots
x = [-12 ± √(12² – 4(-2)·32)] / [2·(-2)]
= [-12 ± √400] / (-4)
= [-12 ± 20] /(-4)

Nelda needs to wrap a holiday gift box. The box is in the shape of a rectangular prism with the dimensions shown.
Answer:
416 in²
Step-by-step explanation:
Given that:
Height. h = 4 in
Length = 12 in
Width = 10 in
The surface area of a rectangular prism is obtained using the relation :
Surface Area, S = 2(lw + lh + wh)
S = 2[(10*12) + (10*4) + (12*4))
S = 2(120 + 40 + 48)
S = 2(208)
S = 416 in²

sine = soh=o/h
cos=cah=a/h
tangent=toa=o/a
If you look at right triangle the slanted line is the hypothese. it will always be. so thats h. the adjacent is the line connected the the angle you are looking for. and opposite is the line thats away from the angle.
