Answer:
Subtracting the polynomials we will get: [tex]\mathbf{-4x^2-4x+5}[/tex]
Step-by-step explanation:
We need to u se a vertical format to subtract the polynomials.
The polynomials given are:
[tex]3x^2 - 2x + 2\\- (7x^2 + 2x - 3)[/tex]
Now, solving
For, subtraction, the sign of the terms [tex]7x^2 + 2x - 3[/tex] will be changed. - will convert to + because (-)(-) = + and positive sign will be converted to negative (-)(+) = -
The sign with the resulting term will be the sign of term that has greater coefficient. For example if we are subtracting 3x^2 and (-7x^2), the result will be -4x^2 because 7 has negative sign. (term has greater coefficient)
[tex]3x^2 - 2x + 2\\- (7x^2 + 2x - 3)\\\\:\:\:\:\:\:\:-\:\:\:\:-\:\:\:\:\:+\\-----------\\-4x^2-4x+5[/tex]
So, Subtracting the polynomials we will get: [tex]\mathbf{-4x^2-4x+5}[/tex]
A tree is 15 feet tall. A building is 75% taller than the tree. How tall is the building?
a) 27 feet
b) 18.75 feet
c) 16.125 feet
d) 26.25 feet
Answer:
D
Step-by-step explanation:
The building is 75% taller than the tree (15ft). So you would turn the percent into a decimal, 0.75, and multiply it by 15 to get 11.25. therefore add 11.25 to 15 and get 26.25. Sorry if the explanation isn't up to par

what is
the equation of the line that passes through the points (-6,6) and (-1,-9)
Answer:
The answer to the question provided is y = -3x - 12.
Step-by-step explanation:
❃Incase you forgot what the linear equation formula is ☟
[tex]y = mx + b[/tex]
❃Incase you also forgot, what the slope formula is ☟
[tex]m = \frac{y_2 - y_1 }{x_2 - x_1}[/tex]
➊ First: We are going to be solving for the slope.
[tex]m = \frac{ - 9 - 6}{ - 1 - ( - 6)} = \frac{ - 15}{ \: \: \: 5} = - 3[/tex]
➋Second: We find the y-intercept.
[tex]y = mx + b \\ 6 = - 3( - 6) + b \\ 6 = 18 + b \\ \frac{ - 18 = - 18 \: \: \: \: \: \: \: \: \: \: \: \: }{ - 12 = b}[/tex]
➌Third: Plug in.
[tex]y = - 3x - 12[/tex]

Find each unknown number. a. 12 is 150% of what number? b. 5 is 50% of what number? c. 10% of what number is 300? d. 5% of what number is 72? e. 20 is 80% of what number?
The unknown values of number for each of the expression is 8, 10, 3000, 1440, and 25.
What is Percentage?A percentage is a portion of a whole number which is expressed as a number between the range of 0 and 100 rather than as a fraction. All of a thing is 100 percent, half of it is 50 percent, and none of something is zero percent. To determine a percentage, we divide the portion of the whole through the whole of itself and multiply it by 100.
x × 150/100 = 12
x = 12 × 100/ 150
x = 1200/ 150
x = 8
x × 50/100 = 5
x = 5 × 100/ 50
x = 500/ 50
x = 10
x × 10/100 = 300
x = 300 × 100/ 10
x = 30000/ 10
x = 3000
x × 5/ 100 = 72
x = 72 × 100/ 5
x = 7200/ 5
x = 1,440
x × 80/ 100 = 20
x = 20 × 100/ 80
x = 2000/ 80
x = 25
Therefore, the values of unknown numbers are 8, 10, 3000, 1440, and 25, respectively.

A=60
Answer:
3.
Step-by-step explanation:
12a+20a+28a=180(sum of interior angle of a triangle )
or, 60a=180
or, a= 180/60
therefore ..... a=3
The angle of a quadrilateral are in the ratio 4:6:3 and it's fourth angle is 100. Find the other three angles of the quadrilateral
Step-by-step explanation:
Sum of angles in a quadrilateral = 360°
Sum of first 3 angles = 360° - 100° = 260°.
260° / (4 + 6 + 3) = 20°.
First angle = (20°) * 4 = 80°
Second angle = (20°) * 6 = 120°
Third angle = (20°) * 3 = 60°
The angles are 80°, 120° and 60°.
Answer:
Let the angles of the quadrilateral be 4x, 6x, and 3x
Sum of the interior angles of a quadrilateral is 360°.
According to the above problem,
[tex]4x + 6x + 3x + 100 = 360 \\ 13x = 360 - 100 \\ 13x = 260 \\ \boxed{x = 20}[/tex]
1st angle=4x=4×20=80°2nd angle=6x=6×20=120°3rd angle=3x=3×20=60°Hence, the other three angles are 80°, 120° and 60°.
What is the image point of (7,-7) after a translation of 3 right and 1 down followed by
a reflection over the x-axis?
Answer:
The image point of P(7,-7) after a translation of 3 right and 1 down followed by a reflection over the x-axis will be:
P''(10, 8)Step-by-step explanation:
Given the point
(7, -7)
Translation of 3 right and 1 down means we need to add 3 units to the x-coordinate and subtract 1 unit from the y-coordinate
Therefore, the translation rule:
(x, y) → (x+3, y-1)
In our case, let the point P(7, -7)
P(7, -7) → P'(7+3, -7-1) → P'(10, -8)
FOLLOWED BY A reflection over the x-axis
We know that the rule of reflection over the x-axis implies that
(x y) → (x, -y)
i.e. the x-coordinate of the point remains the same, but the y-coordinate changes its sign.
After the first transformation, we had got P'(10, -8)
so
P'(10, -8) → P''(10, -(-8)) → P''(10, 8)
Therefore, the image point of P(7,-7) after a translation of 3 right and 1 down followed by a reflection over the x-axis will be:

The Quick Ship company uses the function C(w) to calculate the cost in dollars, C, for shipping an item
weighing w ounces.
5 0.450 if 0
C(w) =
0.35W + 1.6 if w > 16
Which statement about the shipping rate is true?
Shipping at the second rate will always cost $1.60 more than shipping
at the first rate.
If the weight is greater than 16 ounces, the shipping rate is $0.35 per
ounce, plus $1.60.
It is possible that an item weighing less than 16 ounces could cost the
same as an item weighing more than 16 ounces.

To find the charge for shipping a package weighing more than
16 ounces multiply the weight by $0.35.
+
Answer:
A: Shipping at the second rate will always cost 1.60 more than shipping at the first rate.
Step-by-step explanation:
The following points for the function C(w) can be concluded as
The function C(w) is valid only for {w} greater than 16 ounces.The initial cost is $1.6.The cost of shipping per ounce is $0.35.What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that the Quick Ship company uses the function C(w) to calculate the cost in dollars {C} for shipping an item weighing {w} ounces as
C(w) = 0.35W + 1.6 if {w > 16}
The given function is -
C(w) = 0.35w + 1.6 if {w > 16}
We can conclude the following points for the function C(w) -
The function C(w) is valid only for {w} greater than 16 ounces.The initial cost is $1.6.The cost of shipping per ounce is $0.35.Therefore, the following points for the function C(w) can be concluded as
The function C(w) is valid only for {w} greater than 16 ounces.The initial cost is $1.6.The cost of shipping per ounce is $0.35.To solve more questions on algebraic expressions, visit the link below -
