Simplify 5x + 3 -2x + 1
Answer:
3x+4
Step-by-step explanation:
When simplifying expressions, you need to combine like terms. 5x and -2x combined would equal 3x. Since the 2x was negative, you needed to subtract. Next, you combine 3 and 1, which should equal 4.
When putting the expression back together, make sure you leave it in the same order as received. This would mean you would put the coefficient with the variable first, and then put the whole number.
Make sure to take the signs into account. If it is negative, you subtract, and if it is positive, you add.

becky spends 3/5 of her money she has left £60 left. how much money did she start with?
Answer: $150
Step-by-step explanation:
Becky spends 3/5 of her Money and is left with 2/5 of her money.
Hence 2 parts = $60
And 5 parts = $150
Becky has $150 at first.
Becky starts with $150.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Becky spends 3/5 of her money she has left £60 left.
let Becky earned be x.
so, x- 3/5x= 60
2x/5 = 60
x= 300/ 2
x=$150
Hence, Becky starts with $150.

Consider this polynomial.
p(x)=3x^3+11x^2-4x-6
Which statements are true?
Answer:
C, D
Step-by-step explanation:
1.)
the best way to figure this out is just plug in -2 for x
3(-2^3)+11(-2^2)-4(-2)-6
I put this into a calculator and get 22
2/3.) see attachment below for work
but C is correct
4.) in number one we determined that p(-2) =22 so yes
5.) we determined in 2/3 that it is in fact not, so no
The correct option for the polynomial is p(x) = 3x³ + 11x² - 4x - 6 are option 3 and option 4.
What is polynomial?ax² + bx + c, where a, b, and c are real numbers with a 0, is the formula for a quadratic polynomial in 'x' with real coefficients.
Degree: The degree of a polynomial is the highest exponent of the variable in the polynomial.
Calculation for the values of polynomial:
Step 1: Calculation for p(-2)To get the value of p(-2), at the place of 'x' put (-2) in the polynomial p(x).
p(x) = 3x³ + 11x² - 4x - 6
p(-2) = 3(-2)³ + 11(-2)² - 4(-2) - 6
p(-2) = 22
Thus, option 4 is correct and option 1 is incorrect.
Step 2: Calculate the quotient of p(x)To calculate the quotient divide the polynomial p(x) by (x +2)
The solution of this is attached in the file.
Therefore, option 3 is correct and option 2 is incorrect.
As, we can see from the division of polynomial p(x) by (x + 2) , the p(x) polynomial is not completely divisible by (x +2). Therefore, option 5 is also incorrect.

Law of Sines: sin A
sin B
b
sin C
С
a
Enter
========================================================
Explanation:
The ultimate goal is to find the value for lowercase c, or find the length of side c. So we'll use the portion sin(C)/c as part of the law of sines.
We don't know the value of lowercase 'a', so we'll ignore the sin(A)/a portion.
This leaves sin(B)/b
We see that one side is 2 cm long, so this means b = 2. The angle opposite this is 105 degrees, so B = 105.
The angle opposite side c is 15 degrees, so C = 15.
The lowercase letters represent side lengths, while the uppercase letters are angles.
--------------------------
We have enough to apply the law of sines to solve for side c.
sin(B)/b = sin(C)/c
sin(105)/2 = sin(15)/c
c*sin(105) = 2*sin(15) ............. cross multiply
c = 2*sin(15)/sin(105) .............. dividing both sides by sin(105)
c = 0.53589838486224
c = 0.5
Side c is roughly 0.5 cm long.
Make sure your calculator is in degree mode.
9514 1404 393
Answer:
0.5 cm
Step-by-step explanation:
The Law of Sines tells you ...
c/sin(C) = b/sin(B)
c = b·sin(C)/sin(B)
c = (2 cm)sin(15°)/sin(105°) ≈ (2 cm)(0.2588/0.9659) ≈ 0.5359 cm
c ≈ 0.5 cm . . . . rounded to tenths
