Answer:
Step-by-step explanation:
a) Sum = - 6
Product = - 16
Factors = (-8) ; (2 {-8 + 2 = -6 ; (-8) * 2 = -16}
y = x² - 6x - 16
= x² + 2x - 8x - 16
= x(x + 2) - 8(x + 2)
= (x +2)(x -8)
b) y = 0
(x +2 )(x -8) = 0
x + 2 = 0 ; x - 8 = 0
x = -2 ; x = 8
(-2) ; 8 are the zeros.

A drinking glass is in the shape of a cylinder. The volume of the glass is 2211.68 cubic centimeters, and its diameter is 16 centimeters. Find the height of the glass.
Round the answer to the nearest centimeter. Include the units in your typed answer.
Answers
Answer:
11cm
Step-by-step explanation:
diameter = 16, r = 8 (16÷2)
π = 3.142
V=πr2h
2211.68 = π x 8^2 x h
2211.68 = 3.142 x 64 x h
2211.68 ÷ 64 ÷ 3.142 = h
h = 10.9986
= 11 cm (round off to nearest cm)
To check and confirm
V=πr2h
3.142 x 64 (8^2) x 10. 9986 = 2211.68

A line passes through 2, -9 and parallel to a line passing through points (8,-4) and (6, 4)

Help please
Answers
Answer:
Yo Rick Astley
Step-by-step explanation:
y ∝ 1 √ x
y = k (1 √ x)
y = 7 when x = 36
7 = k ( 1 / √36)
7 = k (1/6)
k= 7 × 6
k = 42
If x = 4 then,
y = 42 ( 1/√4)
y = 42 ( 1/2)
y= 21

choose the correct solution and graph for the inequality "-x/3<=6"
Answers
Answer:
Step-by-step explanation:
To solve this inequality, we have to find x (or make x the subject of the inequality:
since ⁻ˣ/₃ ≤ 6 [multiply both sides by 3]
- x ≤ 18 [multiply both sides by -1; this flips the inequality sign]
x ≥ - 18 [this is the solution]To graph the inequality, draw the line x = - 18 with a solid line, and then shade the region that is x > -18.
We use a solid line because the point x = -18 is included. However, hypothetically, if the inequality was x > -18 only, a broken line would be used to show that the line x = -18 is not included.

X=16x
z=116
16x+112=128
360-128=232
232 divide by 2=116
Answer:
x = 9
z = 68
Step-by-step explanation:
For x, the top and bottom angles have the same value. To get x, you need to set up this equation: 12x + 4 = 112. Subtract 4 from itself and from 112. Your equation will then be 12x = 108. Divide 108 by 12, and then your answer is 9. So the value of x is 9.
For z, it's supplementary with the top angle. This means that the two angles combined add up to 180. So your question is: 112 + z = 180. Subtract 112 from 180, and then your answer is 68. So the value of z is 68.

What is an equation of the line that passes through the points (4,4) and
(8, 1)?
Answers
Answer:
y = -3/4x + 7
Step-by-step explanation:
ok first u need to find the slope so use the slope equation for this (x2 - x1 over y2 - y1) so
1 - 4 = -3
8 - 4 4
so the m is -3/4
now you need to find the y intercept so pick one of the points (let's do (8, 1)) and plug that into the slope intercept form (y = mx+b)
so 1 = -3/4(8) + b
1 = -6 + b
+ 6 + 6
b = 7
so the equation is y = -3/4x + 7. hope this helps

Explanation:
Relation I has each item in the domain map to exactly one item in the range. So any input leads to exactly one output. Therefore, we have a function here.
In contrast, relation II has the input x = 0 lead to multiple outputs (namely y = 8 and y = -1 at the same time). This indicates we do not have a function here.
Relation III is the same as as the previous one. This time the input x = -2 maps to both y = 1 and y = -7 at the same time. We don't have a function here either.
If you wanted, you can plot these points on the xy plane to see that relations II and III fail the vertical line test. You would need to plot each relation separately.
JEN PURCHASED THE ITEM SHOWN IN THE TABLE IN THE CITY IN THE SALES TAX RATE IS 7.15 IN ANOTHER CITY THE SALES TAX RATE IS 6.35 HOW MUCH MORE IS SHE SPENDING IF SHE PURCHASED THE ITEM==EN IN THE CITY WHERE SHE LIVES
Answers
Answer:
First, calculate the amount of sales tax by multiply the percent tax times the total cost:
0.07×600 =42
Next, add the amount of tax to the price of the computer:
600+42=642
$0.45792 more is she spending if she purchases the items in the city where she lives.
Given that, Jen purchased the items shown on the table. In the city she lives in, the sales tax rate is 7.15%. In another city, the sales tax rate is 6.35%.
We need to find out how much more is she spending if she purchases the items in the city where she lives.
What is the sales tax?A sales tax is a consumption tax imposed by the government on the sale of goods and services.
Now, the cost of the goods she purchased=11.99+35.50+6.75+3.00
=$57.24
The sales tax rate is 7.15%.
So, the sales tax=7.15% of 57.24
=$4.09266
The sales tax rate is 6.35%.
So, the sales tax=6.35% of 57.24
=$3.63474
Now, 4.09266-3.63474=$0.45792
Therefore, $0.45792 more is she spending if she purchases the items in the city where she lives.
