if a number is added to it's square, the result is six. Find the number
Answer:
is the number 2?
Step-by-step explanation:
Answer:
The number could be
1 1/2 or -2
explanation:
From the data, taking the number to be x, we write:
2x^2 + x =6
Subtract 6 from both sides.
2x^2 + x - 6 = 0
Factorise.
2x^2 + 4x - 3x - 6 = 0
2x(x + 2) - 3(x + 2) = 0
(2x - 3)(x + 2) = 0
2x - 3 = 0 or x +2 = -2
x = 3/2 = 1 1/2 or x = -2
Question 6

Find the equation of the line through the points (-4,6) and (1,-9). Write your answer in the form
y = mx + b.
Answer:
m=Y2–Y1/X2–X1
[tex]m = \frac{ - 9 - (6)}{1 - ( - 4)} \\ m = \frac{ - 15}{5} = - 3 \\ y = mx + b \\ y = - 3x + b[/tex]
Answer: y = -5x - 14
Step-by-step explanation:
first find the difference between the x variables x1 = 1 and x2=-4 to find the slope(m)
-4 - 1 = -5
next find the difference between the y variables to find b
-9 - 6 = -14
PLEAASE help asap plzz <3 the question is in the file/attachment :) its 60 points <3
Answer:
Step-by-step explanation:
y=1/2x+1
y=mx+b where m=slope and b=y-intercept
in this case, m=1/2, b=1
y-intercept: (0, 1)
---------------------------------
y=-x+4
y=mx+b where m=slope and b=y-intercept
in this case, m=-1, b=4
y-intercept: (0, 4)
------------------------------------
1/2x+1=-x+4
1/2x-(-x)+1=4
1/2x+x=4-1
1/2x+2/2x=3
3/2x=3
x=3/(3/2)
x=(3/1)(2/3)
x=6/3
x=2
substitute x=2, into y=1/2x+1
y=1/2(2)+1=1+1=2
x=2, y=2.
The lines intersect at point (2, 2).
answer:
Y=1/2x+1 M=1/2 and B=1 Y internsept is 1
Y=-x+4 M=-1 and B=4 Y-internsept is 4
Lines will internsept at (2,2)

The area of a rectangle is 350 square meters. Find its width if its length is 50 meters
Step-by-step explanation:
For a given rectangle,the area(A) is the product of its length and width
A=lw, given A=350m² and l=50m
transposing the equation for w gives w=A/l
w=350m²/50m=7m

9514 1404 393
Answer:
∠A = 66°
Step-by-step explanation:
The other base angle (∠B) of this isosceles triangle is also 57°. Of course, the total of all angles is 180°, so we have ...
∠A +∠B +∠C = 180°
∠A + 57° + 57° = 180° . . . fill in the known numbers
∠A = 66° . . . . . . . . . . . . . subtract 114° from both sides
You open a case of Cherry Coke from the garage to put cans in the refrigerator. You put the
85°F cans in the 36°F refrigerator. After 5 minutes, the can temperature has gone down to
71°F. Find the constant "k" using Newton's Law of Cooling.
9514 1404 393
Answer:
k ≈ -0.06729
Step-by-step explanation:
The initial temperature difference is 85 -36 = 49 degrees. After 5 minutes, the temperature difference is 71 -36 = 35 degrees. The constant k is the natural log of the ratio of these temperature differences, divided by the time unit.
k = ln(35/49)/5 ≈ -0.06729
__
The equation for the temperature T of the can in the refrigerator is ...
T = 49e^(-0.06729t) +36
_____
Additional comment
Be careful with the sign. If you're filling in k in e^(-kt), then the sign of k will be positive. Above, we have taken the form of the exponential term to be e^(kt), so k is negative.

Answer:
Combination
Step-by-step explanation:
Permutation is the act of arranging the objects or numbers in order. Combinations are the way of selecting the objects or numbers from a group of objects or collection, in such a way that the order of the objects does not matter.

Problem 7
Answer: 60-----------------------
Explanation:
Let's say we only worried about the colors and the sizes. We have 3 colors and 4 sizes, giving 3*4 = 12 different combos. Think of a table that's 3 rows and 4 columns. We'd have 12 inner cells. Each cell represents a different combo.
This idea extends out to not just two factors, but we can have as many as we want. In short, we simply multiply the values given to us: 3*4*5 = 12*5 = 60 different t-shirts. Your math textbook or your teacher may refer to this method as the counting principle, though they may use another term.
========================================================
Problem 8
Answer: 224-----------------------
Explanation:
We use the same idea as problem 7.
4*7*8 = 28*8 = 224 different coats
As an alternative, you can draw out a tree diagram. However, these types of drawings can get very cluttered.
========================================================
Problem 9
Answer: 5040-----------------------
Explanation:
We'll use the same idea as before.
We have 10 choices for the first slot (0 through 9)
Once the first digit is selected, then we have 10-1 = 9 choices left for slot two
Then slot three has 9-1 = 8 choices, and so on.
We have this countdown: 10, 9, 8, 7
The countdown stops once we filled out the four slots. Multiply these values to get the final answer: 10*9*8*7 = 5040. The multiplication step is where we refer to the ideas mentioned in problems 7 and 8 earlier.
Keep in mind that this allows for 0 to be in the first slot. So a number like "0179" is one possibility here. If 0 is not allowed for the first digit, then you'll compute the answer like so:
9*9*8*7 = 4536
This is because we have 9 choices for the first digit, then 9 for the next, and so on. I would ask your teacher for clarification on this one.

Answer:
x=72
y=54
Step-by-step explanation:
1st question. y=54 because it is a bisector of the 108 degree angles. (a polygon's interior angles add to number of sides minus 2 times 180)
There are two ys, so they add up to 108. A triangle's interior angles add to 180. 180-108 =72 x=72
2nd question, x is 72 ( it says x is the same measure) so 180-72=2y.
y still equals 54

Jasmine made a new line plot for the lengths of another set of strings that the art teacher gave her for a new project. Two line plots are given. 1st line plot named as ALTDCString Lengths for Craft ProjectALTDC shows a number line from 6 to 14. The number line is divided into 4 equal parts. 1 cross on 6, 2 crosses on 8, 4 crosses on 12 and 1 cross on 14 is given. 2nd line plot named as ALTDCString Lengths for New ProjectALTDC shows a number line from 6 to 14. The number line is divided into 4 equal parts. 2 crosses on 8, 3 crosses on 10 and 3 crosses on 12 is given. Which of the following statements are true about the string lengths for the first craft project and the new project? Select all that apply. A. There are half as many 12-inch strings for the new project as for the craft project. B. There are twice as many 8-inch strings for the craft project as for the new project. C. Jasmine has the same number of strings for the new project as for the craft project. D. The total length of the strings for the craft project is greater than the total length for the new project. E. The length of the longest string is the same for both projects.
Answer:
C - Jasmine has the same number of strings for the new project as for the craft project
D - The total length of the strings for the craft project is greater than the total length for the new project.
The length of all the strings combined is 84 inches, while the length of the smallest string is 6 inches.
What is a line plot?A line plot is a graph that shows the frequency of each value by displaying data as points or checkmarks above a number line.
here, we have,
In the given line plot, if we consider each of the options with the plot given to us, we will get to know which of the options are true or not.
A.) A. The difference between the longest length and shortest length is 14 inches.
As given in the plot, the longest string is 14 units while the smallest is 6 units, therefore, the first option is incorrect.
B.) I have twice as many 12-inch strings as I do 8-inch strings.
In the plot since the number of dots represents the number of strings of a particular length, therefore, the number of strings of length 12-inches is 4 and the number of strings of length 8-inches is 2. Thus, the given options are correct.
C.) The total length of string that I have is 84 inches.
As per the plot, the number of strings of length 6 inches is 1, the number of strings of length 8 inches is 2, the strings of length 12inches is 4, and the number of strings of length 14 inches is 1. Thus, the sum of the length of all the strings is 84 inches.
Hence, the statement is correct.
D.) I cannot determine what the shortest string is by looking at my line plot.
As given in the plot, the length of the smallest string is 6 inches, thus, the statement is incorrect.
E.) Since I need 100 total inches of string for my project, I have enough string.
As the length of all the strings combined is just 84 inches, thus, the statement is incorrect.
Hence, the only option that is correct is 'B' and 'C'.
