-3 is a zero for the polynomial:
x^3 + 7x^2 + 16 x + 12
True or False
Answer:
true
Step-by-step explanation:
If x = - 3 is a zero of the polynomial then f(- 3) = 0
f(x) = x³ + 7x² + 16x + 12
= (- 3)³ + 7(- 3)² + 16(- 3) + 12
= - 27 + 63 - 48 + 12
= 0
Since f(- 3) = 0 then x = - 3 is a zero of the polynomial

Answer:
y = -5/2x +4
Step-by-step explanation:
First, make the equation into standard form.
5x + 2y = -10
2y = -5x - 10
y = -2.5x - 5
In order for two lines to be parallel, they must have the same slope. (In y = mx + b, "m" is the slope)
The slope in y = -2.5x - 5 is -2.5, so we need to find an equation with a slope of -2.5 (or -5/2)
In y = -2/5x - 8, the slope is -2/5
In y = 2/5x + 7, the slope is 2/5
In y = 5/2x - 6, the slope is 5/2
In y = -5/2x +4, the slope is -5/2.
Thus, y = -5/2x +4 is the right answer

1/7^3 (One over seven thirds)
Step-by-step explanation:
Write in Slope Intercept form
Answer:
y=5/2x
Step-by-step explanation:
the y intercept is (0,0) so it isn't included in the equation. now we know the middle solution isn't correct. the points we use to find slope are (-2,-5) and (2,5) which ends up being 5/2.
Find the slope of the line passing through the points (7, 8) and (7,-9).
Answer:
the slope is undefined

j - 18 = 61
Step One: Add your addend and your total together.
18 + 43 = 61
Step Two/Check: Subtract your original total with one of your original addend to get the second original addend you had before.
61 - 18 = 43
Answer:
j = 61

Find the volume of the cylinder. Use 3.14 for pi. Round your answer to the nearest tenth.
Answer:
The formula for the volume of a cylinder is V=Bh (where B is the base) or V=πr2h . The radius of the cylinder is 9 ft and the height is 6 ft. Substitute 9 for r and 6 for h in the formula V=πr2h = (3.14) (9) (2) (6) =339.12
Step-by-step explanation:
Now C=339.12 round to the nearest tenth is 339.1

At a sale, coats were sold for 52% of their original price. If the coats originally cost
$200 each, how much did a coat cost on sale?
Help me please
Answer:
Answer is 104
Step-by-step explanation:
The selling price of the coat is $104.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Original price = $200
Selling price.
= 52% of $200
= 52/100 x 200
= $104
Thus,
$104 is the selling price of the coat.

Use quadrilateral ABCD. What value for m DAB would show ABCD is a parallelogram?
Answer:
m∠DAB = 101°
x = 7
y = 12
Step-by-step explanation:
Properties of a parallelogram,
1). Opposite sides of a parallelogram are equal and parallel.
2). Opposite interior angles are equal in measure.
3). Consecutive interior angles are supplementary.
By the first property,
BC ≅ AD
2x + 4 = 3x - 3
3x - 2x = 4 + 3
x = 7
AB ≅ CD
2y + 10 = 3y - 2
3y - 2y = 10 + 2
y = 12
By second property,
m∠ABC = m∠ADC
2z + 15 = 3z - 17
3z - 2z = 15 + 17
z = 32
Therefore, m∠ADC = (3z - 17)°
= 3(32) - 17
= 96 - 17
= 79°
By third property,
m∠ADC + m∠DAB = 180°
79° + m∠DAB = 180°
m∠DAB = 180° - 79°
m∠DAB = 101°
