[tex] - 4a - (8a + 1) = - 169 \\ \\ 4a + 8a + 1 = 169 \\ \\ 4a + 8a = 169 - 1 \\ \\ 12a = 169 - 1 \\ \\ 12a = 168 \\ \\ a = \frac{168}{12} \\ \\ a = 14 \\ \\ this \: was \: helping \: you[/tex]
Step-by-step explanation:
Okay so remember the BODMAS rule where u start with brackets right; Since we're proving that RHS =LHS ,we look at the side which is more complicated and solve it first.
RHS: -4a-(8a+1) =-169
-4a-8a-1=-169
-4a-8a= -169+1 ( N:B like terms)
-12a= -168
-12a/-12= -168/-12
a= 14
Then go back to the original equation and subtitute .
where u see a u put the value u calculated.
-4a-(8a+1)=-169
-4(14)-(8(14)+1)= -169
-169= -169 and u DONE!!

Hello!
The slope equation is y = mx + b
mx is the slope and b is the yintercept.
4. y= -3x + 5
See where I put the slope and y intercept above?
Those are where the numbers go in that equation.
5. 3x + y = 5
The standard for equation is: Ax + by = c
y = -3x + 5
we need to make the equation look like the standard form equation.
y = -3x + 5
lets add 3x to both sides
The answer is 3x + y = 5
6. m = [tex]\frac{3}{2}[/tex]
We need to use this formula: [tex]m=\frac{y2-y1}{x2-x1} \\\\\\[/tex]
The points said are: (2, 5) and (4, 8)
[tex]m=\frac{8-5}{4-2}[/tex]
m = 3/2
M is the slope.

decided to make a new rug that was smaller than his original rug. The area of the new rug
is 4x2
square feet
Which of the following expressions represents the difference between the area of his old
rug and the area of his new rug?
Answer:
7x + 3
Step-by-step explanation:

–13b–12>3 or 14b–11≥–3
Write your answer as a compound inequality with integers, proper fractions, and improper fractions in simplest form.
Answer: b < -15/13 or b ≥ 4/7
Step-by-step explanation:
-13b - 12 > 3 can be simplified to -13b > 15 through subtraction. Then, dividing by a negative number flips the greater than sign to a less than, so you get b < -15/13 .
The other equation can be solved in the same way. 14b ≥ 8 is found through addition; and dividing by a positive number doesn't flip the greater than or equal to sign, so you end up with b ≥ 8/14, which simplifies to b ≥ 4/7.
These solutions diverge, or go in opposite directions: one is a less than equation, and the other a greater than, so you're looking for an answer with an 'or' in between them. Therefore, you can eliminate the answers on the top left and bottom right, which converge.
You can also eliminate the answer on the top right, because it has a less than or equals to symbol in the b < -15/13 equation where it's supposed to be a simple < symbol.
What are Similarities and differences between Inequality Notation, Set Builder Notation, and Interval Notation
Answer:
As the question states - it's just a different notation to express the same thing.
When you represent a set with set notation, you look for a characteristic that identifies the elements of your set. For example, if you want to describe the set of all number greater than
2
and less than
10
, you write
{
x
∈
R
∣
2
<
x
<
10
}
Which you read as "All the real number
x
(
x
∈
R
) such that (the symbol "|")
x
is between
2
and
10
(
2
<
x
<
10
)
On the other hand, if you want to represent the set with interval notation, you need to know the upper and lower bound of the set, or possibly the upper and lower bound of all the intervals that compose the set.
For example, if your set is composed by all the numbers smaller than
5
, or between
10
and
20
, or greater than
100
, you write the following union of intervals:
(
−
∞
,
5
)
∪
(
10
,
20
)
∪
(
100
,
∞
)
This same set can be written in set notation:
{
x
∈
R
∣
x
<
5
or
10
<
x
<
20
or
x
>
100
}
Finally, note that if the characterization of the set is rather complex, the set notation becomes preferable to the interval one, which would require a great number of intervals in the union. In some other cases, it could be literally impossible to write a set in interval notation, for example is you consider only irrational numbers, you write
{
x
∈
R
∣
x
∉
Q
}
but you can't write is as union of intervals.
See explanation below
Step-by-step explanation:
Imagine we have to express
[
a
,
b
]
in set notation
A
=
[
a
,
b
]
, then
A
=
{
x
∈
R
/
a
≤
x
≤
b
}
In this notation we define the characteristics of all
x
belonging to this set
A
…x must be greater or equal to a and simultaneously smaller or equal to b...
Interval notation is other way to say the same but assuming that
[
means the extreme a is IN the interval and
(
means extreme
a
is not.

Find length
__
AB
A:-6
B: 8
To find the distance between those two points you would need to
do, -6 - (8), which is -14, and than take away the minus sign, and the length of AB is 14 units.
Answer:
14 = AB
Step-by-step explanation:
When finding length, absolute value is the way to go! So if A is -6 and b is 8, then we need to find the distance between them. You can physically count on a number line like I see you did, which would be -5,-4,-3,-2,-1,0,1,2,3,4,5,6,7,8=14 numbers
or you can set up the expression---
| -6-8 |
which equals
| -14 |
or
14
because 14 is the same as | -14 |
The average weight of three dogs is 55 pounds, and the average weight of five cats is 9 pounds. What is the average weight, in pounds, of all eight animals?
(A) 8
(B) 12.5
(C) 21.75
(D) 26.25
(E) 46
Answer:
Option D is correct
Step-by-step explanation:
Statement 1
Average weight of 3 dogs = 55 pounds
Total weight of 3 dogs = 55 × 3
Total weight of 3 dogs = 165 pound
Statement 2
Average weight of 5 cats = 9 pounds
Total weight of 5 cats = 9 × 5
Total weight of 5 cats = 45 pounds
New Average = 165 + 45/8
New Average = 210/8
New Average = 26.25 pounds
Answer:
D 26.25
Step-by-step explanation:
55× 3 + 9×5 = 210
210 ÷ 8 = 26.25

What is a Quadratic Function?The quadratic function can represent a quadratic equation in the Standard form: ax²+bx+c=0 where: a, b and c are your respective coefficients. In the quadratic function the coefficient "a" must be different than zero (a≠0) and the degree of the function must be equal to 2.
For solving a quadratic function you should find the discriminant: D=b²-4ac and after that use this variable in the formula: [tex]x=\frac{-b\pm \sqrt{D} }{2a}[/tex]
Properties of Multiplication
The properties of multiplication are:
Distributive: a(b±c)= ab±ac Comutative: a . b = b. a Associative: a(b+c)= c(a+b) Identity: b.1=bHere, you should apply the distributive property for solving this expression.
x*(2x)+2*(x+5) = 2x²+2x+10
After that, you should solve the previous quadratic equation.
D=b²-4ac=4-4*2*10=4-80= -76
Then,
[tex]x_{1,2}=\frac{-2\pm \sqrt{-76} }{2*2}=\frac{-2\pm i*\sqrt{76} }{4}=\frac{-2\pm i*2\sqrt{19} }{4}=\frac{-1\pm i*\sqrt{19} }{2}[/tex]

Trees are planted at intervals of 5 m along side of a 140 m straight path. The first tree is planted at the start of the path and the last tree is planted at the end of the path. Calculate the total number of trees planted.
Distance between first tree and last tree is 140m .
And distance between each tree (d) = 5 m
let's solve for number of trees (n) :
[tex] \hookrightarrow \: (n - 1)d = 140[/tex]
[tex] \hookrightarrow \: (n - 1)5 = 140[/tex]
[tex] \hookrightarrow \: n - 1 = \dfrac{140}{5} [/tex]
[tex] \hookrightarrow \: n = 28 + 1[/tex]
[tex] \hookrightarrow \: n = 29[/tex]
hence, total number of trees = 29.
