Answer:
Step-by-step explanation:
Combine the equations
-3x + 2y = -8
3x – 2y = 8
obtaining:
-3x + 2y = -8
3x – 2y = 8
-------------------
0 + 0 = 0

A. 3 - 3x2 + 2x + 14
B. x3 + 4x2 - 19x + 14
C. x°- 3x + 14
D. 2 - 2x + 9
Answer: B.x^3+4x^2-19x+14 is correct
Step-by-step explanation:

Multiplying both
x^3-3x^2+2x+7x^2-21x+14
x^3+4x^2-19x+14
After expanding the given equation, the equivalent expression is found to be [tex]x^3 + 4x^2 -19x +14[/tex]
The correct answer is B
Given expression:
[tex](x + 7)(x^2 - 3x + 2)[/tex]
To find:
the equivalent expression in expanded formThe given expression can be expanded as follows;
[tex](x + 7)(x^2 - 3x + 2)\\\\remove \ the \ bracket \ by \ multiplying \ through \ with \ "x" \ and \ "7"\\\\x(x^2 - 3x + 2) + 7(x^2 - 3x + 2)\\\\x^3 - 3x^2 + 2x + 7x^2 - 21x+ 14\\\\simplify \ further \ by \ collecting \ similar \ terms \ together\\\\x^3 + (-3x^2 + 7x^2)+ (2x-21x) + 14\\\\x^3 + 4x^2 - 19x+ 14[/tex]

(a) Solve the equation 4 cos x + 2 = 3 for 0° < x < 360°.
Answer:
divide both sides by cosx
4 sinx/cosx = 1
4 tanx = 1
tanx = 1/4
x = arctan(1/4) = 14.04°
but the tangent is also positive in quad III
so x = 180+14.04 = 194.04°
x = 14.04° or 194.04°

What is trigonometry?Trigonometry is mainly concerned with specific functions of angles and their application to calculations. Trigonometry deals with the study of the relationship between the sides of a triangle (right-angled triangle) and its angles.
For the given situation,
The equation is 4 cos x + 2 = 3 for 0° < x < 360°.
⇒ [tex]4cosx=3-2[/tex]
⇒ [tex]4cosx=1[/tex]
⇒ [tex]cosx=\frac{1}{4}[/tex]
⇒ [tex]x=cos^{-1} (\frac{1}{4} )[/tex]
⇒ [tex]x=75.52[/tex]
Hence we can conclude that the value of x is 75.52°.

What is the value of x? *
31°
53°
Answer:
X = 96
Step-by-step explanation:
This one is pretty simple
So we're dealing with angles here.
So what we want to do is add the two angles and it =180
Here's the equation so it makes more sense:
[tex]A+B=180[/tex]
so we'd place in those numbers
[tex]53+31=180[/tex]
add the two angles together
[tex]53+31=84[/tex]
than we'd subtract from 180 getting the value of X
[tex]180-84=96[/tex]

Dan gets a senior citizen’s discount of 20% for any purchase at the local auto parts store. He bought an item that was half price. If the item originally cost $43, what did Dan pay?
Answer:
$4.30
Step-by-step explanation
$43 x %50 = $21.50
$21.50 x %20 = $4.30
If the item originally cost $43 then Dan paid $17.20 for the item after the discount.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that Dan gets a senior citizen’s discount of 20% for any purchase at the local auto parts store.
We have to find the amount paid by Dan after the discount.
If the original price of the item was $43 and it was half price, then Dan paid:
$43 / 2 = $21.50
Dan also gets a 20% discount on this price, so the amount he paid after the discount is:
$21.50 - 0.20($21.50) = $17.20
Therefore, Dan paid $17.20 for the item after the discount.

A carpenter lays 18 square feet of tile in 2/3 of an hour. How many square feet of tile does the carpenter lay per hour?
Answer:
x=24
Step-by-step explanation:
there are different ways to solve the problem
set up a proportion:
16/(2/3)=x/1
cross multiply
(2/3)x=16
(3/2)(2/3)x=(3/2)(16)
x=24 square feet per hour
a carpenter lays 16 square feet in 40 minutes (2/3 of an hour)
this means he lays 4 square feet every 10 minutes
8 square feet in 20 minutes
12 square feet in 30 minutes
24 square feet in 60 minutes
