General Formulas and Concepts:
Pre-Algebra
Distributive PropertyAlgebra I
Combining Like TermsStep-by-step explanation:
Step 1: Define
f(x) = 5x² - 3
g(x) = x² - 4x - 8
(f - g)(x) is f(x) - g(x)
Step 2: Find (f - g)(x)
Substitute: (f - g)(x) = 5x² - 3 - (x² - 4x - 8)Distribute -1: (f - g)(x) = 5x² - 3 - x² + 4x + 8Combine like terms: (f - g)(x) = 4x² + 4x + 5Whose puppy weighed the most when the person got it? How much did it weigh? Part c

Step-by-step explanation:
use the product property of exponents to justify that (9^1/2)^2=9
The rule states that
[tex](a^b)^c = a^{bc}[/tex]
So, in your case, you have
[tex](9^{\frac{1}{2}})^2=9^{\frac{1}{2}\cdot 2}=9^1=9[/tex]

Answer:
Option 4
Step-by-step explanation:
Coordinances for a three-dimensional coordinate system are (x, y, z).
The letter labeling each axis is always on the positive side.
The fourth option is correct because you move 3 units away from the 'x', 1 unit away from the 'y', then 2 units toward the 'z'.
What are the roots of the equation x2 + 15x = -57 in simplest a + bi form?
Answer:
Step-by-step explanation:
Rewrite x2 + 15x = -57 as x^2 + 15x + 57 = 0, in which the coefficients of this quadratic are {1, 15, 57}.
Then the discriminant is b^2 - 4ac = 225 - 4(1)(57) = -3
Because the discriminant is negative, we know that the two roots will be complex. They are:
-15 ±i√3

Answer:
x = -7.5 ± i(√3)/2
Step-by-step explanation:
We can add (15/2)² to complete the square:
x² +15x +(15/2)² = -57 +(15/2)²
(x +7.5)² = -0.75
x +7.5 = ±i(√3)/2 . . . . take the square root
The roots are ...
[tex]x=\displaystyle\left \{ {{-\dfrac{15}{2}+i\dfrac{\sqrt{3}}{2}} \atop {-\dfrac{15}{2}-i\dfrac{\sqrt{3}}{2}}} \right.[/tex]

2. 4m + t
3. r/t
4. mt
5. 5r + 2m
6. rm
7. 3m - 5t
8. mr/t
Answer:
Step-by-step explanation:
For addition and subtraction, use the standard + and - symbols respectively. For multiplication, use the * symbol. A * symbol is not necessary when multiplying a number by a variable. For instance: 2 * x can also be entered as 2x. Similarly, 2 * (x + 5) can also be entered as 2(x + 5); 2x * (5) can be entered as 2x(5).

jake earned 30 points out of a total of 43 on his most recent math test. on his social studies test, jake scored 85 out of a possible 124 points.
on evict rest did jake score a higher percentage of the total? just your answer.
Answer: See explanation
Step-by-step explanation:
Your question isn't really clear but let me help.
For Maths test,
Point earned = 30
Total point = 43
Percentage = 30/43 × 100 = 69.77%
Social studies test
Point earned = 85.
Total point = 124
Percentage = 85/124 × 100 = 68.55%
From the above, we can see that Jake scored a higher percentage in the Maths test.
Right triangle FGH is shown. Which pair of expressions is equal to 9/41?
A. Sin F and Cos G
B. Sin F and Tan G
C. Tan Fand Sin G
D. Cos F and Sin G
Answer
A
Step-by-step explanation:
use a proportion to find the length of side x for the pair of similar figures
Answer:
30.8
Step-by-step explanation:
1. Write the ratio for the smaller triangle as 14/10 and the ratio for the larger triangle as x/22.
2. Set the ratios equal to each other.
14/10 = x/22
3. Cross multiply and solve for x.
14 x 22 = 308
10 x x = 10x
4. Divide by 10
x = 30.8
Answer:
30.8cm they are correct

In a unit circle, ø = 2pi radians What is the terminal point?
A. (0,1).
B. (0, -1)
C. (-1,0)
D. (1,0)
Answer:
The terminal point is (1, 0) ⇒ D
Step-by-step explanation:
In the unit circle, Ф is the angle between the terminal side and the positive part of the x-xis
The terminal point on the positive part of the x-axis is (1, 0),which means Ф = 0 or 2π radians and cosФ = 1, sinФ = 0The terminal point on the positive part of the y-axis is (0, 1),which means Ф = [tex]\frac{\pi }{2}[/tex] radians and cosФ = 0, sinФ = 1The terminal point on the negative part of the x-axis is (-1, 0),which means Ф = π radians and cosФ = -1, sinФ = 0The terminal point on the negative part of the y-axis is (0, -1),which means Ф = [tex]\frac{3\pi }{2}[/tex] radians and cosФ = 0, sinФ = -1In a unit circle
∵ Ф = 2π radians
→ By using the 1st rule above
∴ The terminal point is (1, 0)
Answer:
(1,0)

21x + 4 = 22x - 2
6 = x
6)
x + 72 + x + 132 = 180
2x + 204 = 180
2x = -24
x = -12
7)
22x + 2 = 90
22x = 88
x = 4
8)
12x + 10 = 13x + 3
7 = x
9)
17x = 16x + 5
x = 5
17(5) = 85°

20x = 21x - 6
-x = -6
x = 6

Which table represents a linear function?
Answer:
bottom right makes the most sense to me
Step-by-step explanation:
10/3 = x divided by -5/2
x =?
Answer:
-0.3x
Step-by-step explanation:
if you divide all of the number up you will get -0.3x
Answer:
Not possible
Step-by-step explanation:
The reason why its not possible is because to figure out a x type of problem, there needs to be a answer to it.
Lets try it solve it to make better sense.
10/3 = 3.33333333333
-5/2 = -2.5.
Divide.
= -1.33333333333.
If this is possible, the answer is -1.33333333333.
Fraction = -4/3.

What is the multiplicative identity of -12/13
A.-13/12
B.1
C.0
D12/13
Answer:
The number '1' is called the 'multiplicative identity' of a number '-12/13' because it does not change the number '-12/13' after getting multiplied by it.
Therefore, option (B) is true.
Step-by-step explanation:
We know that when a number let say 'n' get multiplied by '1', it remains unchanged.
i.e.
n × 1 = n1 × n = nThe number '1' is called the 'multiplicative identity' of a number 'n' because it does not change the number 'n' after getting multiplied by it.
Given the number
-12/13
Multiply the number '-12/13' by '1'.
i.e.
-12/13 × 1 = -12/13
1 × -12/13 = -12/13
Thus, the number '1' is called the 'multiplicative identity' of a number '-12/13' because it does not change the number '-12/13' after getting multiplied by it.
Therefore, option (B) is true.
