Answer:
7x³ + 7x² + 2x - 8
Step-by-step explanation:
Let the unknown polynomial be a
a + -3x³ + 2x - 5 = 4x³ + 7x² - 3
a = 4x³ + 7x² - 3 - (-3x³ + 2x - 5)
a = 4x³ + 7x² - 3 + 3x³ + 2x - 5
a = 7x³ + 7x² + 2x - 8

If the 102,619 residents of a city are divided into 57 equal groups, then some residents don’t fit into a group.
How many residents would be in a group?
How many residents would not fit into a group?
Hey there! Here is your answer:
102,600 would be in a group. 19 would not be in a group.
Step-by-step explanation:
We can figure this out by doing 102,619 divided by 57. This gives us:
1,800 R 19
Now we need to multiply 1800 by 57 to see how many residents there are:
1,800 x 57 = 102,600
Our remainder tells us how many residents would not fit into a group. Since our remainder is 19, 19 would not be in a group.
I hope this helps!
Point P lies on the directed line
segment from A(-2, 4) to B(7, -2), and
partitions the segment in the ratio 1 to 2.
Find the coordinates of P
Answer:
Step-by-step explanation:
The vector AP is in the same directionas AB but its length is 1/3 of AB
No AB = (7-(-2)) i + (-2-4)j = 9i -6j.
It follows that AP = (1/3)(9i-6j) = 3i - 2j.
Now OP = OA +AP = (-2i + 4 j ) + (3i-2j) = i + 2j
So P(1,2).

Rosa completed her chemistry lab in 35.7 minutes. Dale completed the same lab in 36.5 minutes. Who completed their lab first, Rosa or Dale? A Rosa B Dale
Answer:
A. Rosa
Step-by-step explanation:
Since both measurements of time are using the same units, minutes, we can simply compare them and decide which one is the smallest number. The smallest number represents who took the least amount of time and therefore shows who completed their lab first.
35.7 _ 36.5
35.7 < 36.5
Rosa with 35.7 minutes, completed her lab first.
Answer:
Rosa would have finished first
Step-by-step explanation:
If Rosa finished her chemistry lab in 35.7 minutes and Dale in 36.5 it doesn't matter about the decimal 35 comes before 36 therefore Rosa finished first.

Write each decimal as a percent and a fraction -0.04
Answer:
-4% -1/25
Step-by-step explanation:
To convert a decimal to a percentage, multiply it by 100.
-0.04 * 100 = -4
To convert a decimal to a fraction, put the decimal as a fraction over 1 and multiply until the numerator (top number) is a whole number and then simplify.
[tex]\frac{-0.04}{1}[/tex] x [tex]\frac{100}{100}[/tex] = [tex]\frac{-4}{100}[/tex]
-4/100 simplified = -1/25 (because 4 goes into 100 25 times)

3. The sum of the second and third terms of a Geometric Progression is 48. If the sum of third and fourth terms is 144, find the first term of the progression.
Answer:
gọi
Step-by-step explanation:
We have that the first term of the progression is
b=4
From the Question we are told that
Third terms of a Geometric Progression is 48
Sum of third and fourth terms is 144
[tex]x_3+x_4=144[/tex]
Generally the equation for the common ratio is mathematically given as
[tex]\frac{br^2+br^3}{br+br^2}=\frac{144}{48}\\\\\frac{br^2+br^3}{br+br^2}=3[/tex]
r=3
Therefore
Since
[tex]br+br^3=48\\\\b(3)+b(3)^3=48[/tex]
b=4

Given the directed line segment AB: Point A is the _____ with coordinates Point B is the point with coordinates ______.
In the given line segment, the coordinates of Point A and Point B is (1, 3) and (4, 6).
What is a line segment?A line segment in geometry is a section of a straight line that is enclosed by two clearly defined endpoints and contains all of the points on the line that lies inside those endpoints. The Euclidean distance between two ends of a line segment determines its length. A square, for instance, is a two-dimensional geometry with four equal-length sides. In a square, all four interior angles are right angles, and the opposing sides are parallel to one another.So, according to the given image:
Coordinates of point A: (1, 3)Coordinates of point B: (4, 6)Then, Point B is the point with coordinates (4, 6), while Point A is the line (1, 3).
Therefore, in the given line segment, the coordinates of Point A and Point B is (1, 3) and (4, 6).

GL= GR + RL
GL = ( 6x - 3) + (2x+9) = 8x +6
GR = RL
6x - 3 = 2x+9
6x -2x = 9+3
4x = 12 —> x= 12/4 —> x = 3
GR = 6x - 3 = 6(3)-3= 18 -3 =15
RL= 2x+9 = 2(3)+9= 6+9=15
GL = 8x +6 = 8(3)+6=24+6=30

What does f(-2)= 4 mean?
Answer:
f(x) = y
Step-by-step explanation:
Think of it as a input-output function machine, where you give a number as input to the machine, and the you get a number as the output from the machine. The input is x which goes inside of the ( )'s, and the output is f(x). The output 'f(x)' is sometimes called the y-value because y = f(x).
For example f(-2) = 4. The number you give to the machine is -2 since it's the x-value and the number is in ( )'s. The output number the machine gives back to you is 4, which is the y-value.
Hope this helps!
