Find x
X=
Can someone pls help
Answer:
x=10
Step-by-step explanation:
3x+10=6x-20 Set the angles equal to each other b/c they are alt. int. angles.
-3x -3x Subtract by 3x on both sides to get x by itself
----------------
+10 =3x-20
+20 +20 Add 20 to both sides to get x by itself
---------------------
30 =3x
/3 /3 Divide both sides by 3 to get x by itself
-------------
10 =x
x=10 Write x first.

Find the slope of each piece of the antler on the graph below. Write answers in the simplest form into the table.
Answer:
1.) slope = 2
2.) slope = [tex]-2\frac{2}{3}[/tex]
3.) slope = [tex]\frac{2}{3}[/tex]
4.) slope = [tex]\frac{1}{4}[/tex]
5.) slope = [tex]1\frac{8}{9}[/tex]
6.) slope = -2
7.) slope = -3
Step-by-step explanation:
In order to find the slope we have to divide they "y" value (the number of units by which the piece of antler goes up) by the "x" value the number of units by which the piece of antler goes to the side). Notice the if the antler moves to the left as it foes up then the "x" value is negative.
Now as I said before we know this......
Let "m" be the slope, then....
[tex]m = \frac{y}{x}[/tex]
So now we just have to plug in the y and x values for each antler and we will get the slopes for each one of them.
1.)
[tex]m = \frac{y}{x}[/tex]
[tex]m= \frac{4}{2}[/tex]
[tex]m = 2[/tex]
2.)
[tex]m = \frac{y}{x}[/tex]
[tex]m = \frac{4}{-1.5}[/tex]
[tex]m = -2\frac{2}{3}[/tex]
3.)
[tex]m = \frac{y}{x}[/tex]
[tex]m = \frac{2}{3}[/tex]
4.)
[tex]m = \frac{y}{x}[/tex]
[tex]m = \frac{1}{4}[/tex]
5.)
[tex]m = \frac{y}{x}[/tex]
[tex]m = \frac{8.5}{4.5}[/tex]
[tex]m = 1\frac{8}{9}[/tex]
6.)
[tex]m = \frac{y}{x}[/tex]
[tex]m = \frac{2}{-1}[/tex]
[tex]m= -2[/tex]
7.)
[tex]m = \frac{y}{x}[/tex]
[tex]m = \frac{3}{-1}[/tex]
[tex]m = -3[/tex]
Solve the following
equation for X.
3x - 15 = -30
Answer:
X = -5
Step-by-step explanation:
3x - 15 = -30 You want to isolate tha variable
3x= -30+15 Add 15 to -15 in order to get rid of it. All you do to one side you do to the other, so you add 15 to 30
3x= -15
x= -15÷3 Divide x by 3 in order to get rid of the 3. Do it to the other side
x=-5

In the diagram. PQ is parallel to BC.
APB and AQC are straight lines.
PQ = 8 cm, BC = 10 cm and AB = 9 cm.
Calculate PB
Answer:
PB = 1.8
Step-by-step explanation:
PQ = 8 cm, BC = 10 cm and AB = 9 cm
∆ABC is similar to ∆APQ.
Therefore:
[tex] \frac{AB}{AP} = \frac{BC}{PQ} [/tex]
Plug in the values
[tex] \frac{9}{AP} = \frac{10}{8} [/tex]
Cross multiply
AP × 10 = 8 × 9
AP × 10 = 72
Divide both sides by 10
AP = 7.2
PB = AB - AP
PB = 9 - 7.2
PB = 1.8
lily likes to collect records. Last year she had 4 records in her collection. Now she has 7 records. What is the percent increase of her collection?
Answer:
75% increase
Step-by-step explanation:
First we need to figure out how many new records she got this year...
7-4 = 3 new records.
Now, we need to know how many times 4 goes into 100%....
100 ÷ 4 = 25%
This tells us that a single record this year is a 25% increase.
Now, we multiply 25% by 3 to get 75% as our final answer

Step-by-step explanation:
which relation is NOT a function?
Answer:
The relation represented by diagram 4 is NOT a function.
Step-by-step explanation:
To tell if a relation is not a function, pay attention to the x-intercepts. If there is more than one y-intercept with the same x-intercept, then it is not a function, because a function can only have one output (y-value) for each input (x-value).
According to the fourth diagram, the domains include 1, 2, and 3 while the range includes A, B, and C. Also, the ordered pairs would go as follows according to the arrows:
(1, A), (2, A), (2, B), (3, C)
While the y-values, A and B, are different, they share the same input, 2. Therefore, the relation represented by the 4th diagram is NOT a function.
Hope this helps!

x^2 -5x-5x+25
Combine
x^2 -10x+25
Answer:
x^2 - 10x + 25

Use FOIL.
(x - 5)^2 = (x - 5)(x - 5) = x^2 - 5x - 5x + 25 = x^2 - 10x + 25

7/10ths
Step-by-step explanation:
There are ten blocks all together, which is where the 10 comes from, there is 7 shaded that is where the 7 comes from.
Answer:
The percentage is 70%.
Step-by-step explanation:
There are 10 spaces total, and 7 are shaded in. 7 divided by 10 is 0.7.
0.7 as a percentage is 70%.
So 70% of the block is shaded in.

Step-by-step explanation:
Tickets to a band concert cost $10 each. The equation y = 10x represents total cost, y, of x tickets. Which graph shows ordered pairs represented by this equation?
Answer:
the right-hand graph of the first diagram represents ordered pairs which are satisfied by the equation.
The correct graph is attached below.
Step-by-step explanation:
Given the function equation
y = 10xGiven that the cost of each ticket is $10.
It means:
at x = 0, y = 10(0) = 0 ∵ cost of 0 ticket
at x = 1, y = 10(1) = 10 ∵ cost of 1 ticket
at x = 2, y = 10(2) = 20 ∵ cost of 2 tickets
at x = 3, y = 10(3) = 30 ∵ cost of 3 tickets
at x = 4, y = 10(4) = 40 ∵ cost of 4 tickets
at x = 5, y = 10(5) = 50 ∵ cost of 5 tickets
Now, observe the ordered pairs points on the right-hand graph of the first diagram.
This graph has the following ordered pairs:
(0, 0) i.e. at x = 0, y = 10(0) = 0(1, 10) i.e. at x = 1, y = 10(1) = 10 (2, 20) i.e. at x = 2, y = 10(2) = 20 (3, 30) i.e. at x = 3, y = 10(3) = 30 (4, 40) i.e. at x = 4, y = 10(4) = 40 (5, 50) i.e. at x = 5, y = 10(5) = 50Thus, the right-hand graph of the first diagram represents ordered pairs which are satisfied by the equation.
The correct graph is attached below.

Which two ratios form a proportion a) 1:2 and 4:2 b) 1:2 and 2:4 c) 2:1 and 2:4 d) 2:1 and 6:3
Answer:
The ratios in option b and d form a proportion.
Step-by-step explanation:
Option a)
1:2 and 4:2 or 1/2 and 4/21:2 or 1/2 is already in the simple form
Let us reduce 4:2 or 4/2 to check whether it is equal to 1/2 or not
as 4/2 = 2/1 which is NOT equal to 1/2
Thus, 1:2 and 4:2 are NOT in proportions
Option b)
1:2 and 2:4 or 1/2 and 2/41:2 or 1/2 is already in the simple form
Let us reduce 2:4 or 2/4 to check whether it is equal to 1/2 or not
as 2/4 = 1/2 which is EQUAL to 1/2
Thus, 1:2 and 2:4 are in proportions
Option c)
2:1 and 2:4 or 2/1 and 2/42:1 or 2/1 is already in the simple form
Let us reduce 2:4 or 2/4 to check whether it is equal to 2/1 or not
as 2/4 = 1/2 which is NOT equal to 2/1
Thus, 2:1 and 2:4 are NOT in proportions
Option d)
2:1 and 6:3 or 2/1 and 6/32:1 or 2/1 is already in the simple form
Let us reduce 6:3 or 6/3 to check whether it is equal to 2/1 or not
as 6/3 = 2/1 which is equal to 2/1
Thus, 2:1 and 6:3 are in proportions
Therefore, the ratios in option b and d form a proportion.

at the beginning of april, colony of ants has a population of 5,000. During april, the colony decreases by 1/6 of its population. How many ants are there left at the end of april? approximate your answer as an integer(it would not make sense to have 2.5 ants). 5,000
Answer:
4166 ants
Step-by-step explanation:
To find how many ants were left, multiply 5000 by 5/6, since it decreased by 1/6:
5000(5/6)
= 4166.67
Round this down:
= 4166
So, at the end of April, there were approximately 4166 ants left
The required number of ants left at the end of April is given as 4167 ants.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
Let the number of ants at the end of April be x,
According to the question,
Number of ants left = total ants - decreased number of ants
x = 5000 - 1/6[5000]
x = 5000[1 - 1/6]
x = 5000[5/6]
x = 4166.67
x = ≈ 4167
Thus, the required number of ants left at the end of April is given as 4167 ants.

What is the equation of the line that passes through the point (-8, 5) and has a slope of -1/4
Answer:
Step-by-step explanation:
Step one.
Read the slope
-1/4
Step two
Put the slope in the general equation
y = mx + b
y = -1/4 x + b
Step 3
Put the point into the equation from step 2
(-8,5)
5 = -1/4 -8 + b
5 = 2 + b Subtract 2 from both sides
5-2 = b
b = 3
Step 4
Write the entire equation
y = -1/4 x + 3
