#1 determine the slope of :2x+4y=-16 ?
answer
Answer:
-1/2
Step-by-step explanation:
Find the slope by rearranging the equation into y = mx + b form, where m is the slope.
2x + 4y = -16
Subtract 2x from both sides:
4y = -2x - 16
Divide each side by 4:
y = -1/2x - 4
So, the slope is -1/2.

Can I get a good explanation on SAS Triangle Congruence? (35 points)
[tex]\huge{ \mathfrak{ \underline{ Answer} \: \: ✓ }}[/tex]
SAS is a congruency criteria which is used to prove that two triangles are congruent, if two corresponding sides and an angle between them is equal in both the triangles.
For example - In the attached picture,
KL = XY∠KLM = ∠XYZLM = YZTherefore, ΔKLM ≅ ΔXYZ

Which statement best describes the use of a stimulation to predict the probability that two randomly chosen people will both have their birthdays on a monday
Answer:
The answer is "The Last choice".
Step-by-step explanation:
Please find the complete question in the attached file.
It is the phrase that perfectly represents the usage of a simulation for an estimate of the likelihood of the birthday of 2 randomly chosen persons on a Monday.
In a week there are 7 days, so seven choices are available, and just one Monday. Therefore, it is probable that [tex]\frac{1}{7}[/tex] will occur on a Monday to a birthday individual.
The first person will have a probability [tex]\frac{1}{7}[/tex].
The second person also has a probability [tex]\frac{1}{7}[/tex] .

PLEASE HELP PLEASE IM STUCK PLEASEEE
Answer:
Step-by-step explanation:
since it's a square we know the two sides are equal. So set them equal and solve for X
a)
4x + 3 = 3x +17
4x-3x = 17 -3
x = 14
Since we now know X plug it into the expression for the angle
b)
5(14) + 4y = 90 ( 90° b/c we know the angle is equal to that )
70 4y = 90
4y = 90-70
4y = 20
y = 20/4
y = 5
c)
we can find the perimeter by just plugging in X to either of the expressions for the side and then multiplying that by 4, since there are 4 sides
4(14) +3
56 +3
59
now times 4 for each side
59*4= 236
Out of $132,624, how much money will be remaining with the company after purchasing 1184 hard drives for $112 each?
Answer:
$16
Step-by-step explanation:
Given data
Total amount= $132,624
Cost of each hard drive= $112

China consumes 4 x 10^9 tons of coal, while japan about 2 x 10^8 tons of coal. Approximately how many times the amount of that japan consumed did china consumed
Answer:
20 times
Step-by-step explanation:
This is calculated as:
The number of coal China consumes ÷ The number of coal Japan consumes
The number of coal China consumes =4 × 10⁹
The number of coal Japan consumes
= 2 × 10⁸
4 × 10⁹/2 × 10⁸
= 20 times

A right circular cone has a radius of 6 inches and a slant length of 10 inches. A right cylinder has a radius of 8 inches and a height of 12 inches. How many cones full of water are needed to fill the cylinder
Answer:
6.4 cones full of water
Step-by-step explanation:
Given data
Radius of cone= 6inches
Slant height= 10 inches
Volume of cone= 1/3πr^2h
V= 1/3*3.142*6^2*10
V= 1/3*3.142*36*10
V= 1/3*1131.12
V= 377.04 cubic inches
Radius of right cylinder= 8 inches
Height= 12 inches
Volume of cylinder= πr^2h
Volume= 3.142*8^2*12
Volume= 3.142*64*12
Volume=2413.056 cubic inches
Hence the number of cone full of water needed to fill the cylinder is
=Volume of cylinder/volume of cone
=2413.056/377.04
=6.4 cones full of water
2x-y=0 3x=2y=-3
I’m not sure the correct steps to solve.
Answer:
x = 3 and y = 6
Step-by-step explanation:
The given equations are :
2x-y=0 ......(1)
3x-2y=-3 .....(2)
We need to solve equations (1) and (2).
Equation (1) can be written as :
2x = y
Put the value of y in equation (2)
3x-2(2x)=-3
3x-4x = -3
-x = -3
x = 3
Put the valye of x in equation (1)
2(3)-y=0
y = 6
Hence, the value of x = 3 and y = 6.
