what point below is the solution to the expression 2x+y=12
A) (4,2) C) (8,-1)
B) (3,6) D) (0,6)
Answers
Answer:
Step-by-step explanation:
It's B.
Let's rewrite the expression like this :
2x+y=12 ⇒ y=12-2x
and try given values for x :
if x=4 ⇒ y=12-(2×4)=12-8=4 ( so it is not 2 ) ⇒ wrong if x=3 ⇒ y=12-(2×3)=12-6=6 (it is 6) ⇒ right if x=8 ⇒ y=12-(2×8)=12-16=-4 (so it is not -1) ⇒ wrong if x=0 ⇒ y=12-(2×0)=12-0=12 (so it is not 6) ⇒ wrongFind the value of c that will make the following two expressions equivalent.
2a+10b-8-2(4a-6) and -6a+20b+c
Answers
2a+10b-8-2(4a-6) = 2a+10b-8-8a+12
= -6a+10b+12
Now we need to find the value of c that makes -6a+10b+12 and -6a+20b+c equivalent. In order for them to be equivalent, they must have the same coefficients for a and b. The coefficient for a is already the same (-6), so we just need to make the coefficient for b the same:
10b = 20b
10b - 20b = 0
-10b = 0
b = 0
Now that we have found the value of b, we can substitute it back into either expression to find the value of c:
-6a+10b+12 = -6a+10(0)+12
= -6a+12
-6a+20b+c = -6a+20(0)+c
= -6a+c
Since these expressions are equivalent, their coefficients for a must also be equal:
-6a+12 = -6a+c
Simplifying this equation, we find:
12 = c
Therefore, the value of c that makes the two expressions equivalent is 12.

johnny had to work in the morning and 8 hour shift. he clocked in at 8:00am to began working and then clocked back out for 30 min lunch break at 11:06am -11:36 am. he clocked back out at 11:43 am because he got sick. now he has return back to wirk and clocked in at 3:21pm what time will johnny gets off in order to make his 8 hours?
Answers
Answer:
8:08pm.
Step-by-step explanation:
So he worked 3 hours 6 minutes from 8am-11:06am.
Then he worked another 7 minutes from 11:36-11:43am. That brings our running total to 3 hrs 13 minutes.
To work 8 hours, he needs to work 8 hrs - 3 hrs 13 minutes = 4 hrs 47 minutes more.
He's starting a 3:21pm.
First add on the 4 hours. 3:21pm + 4 hours = 7:21pm.
Now add on 47 more minutes. If we add 39 minutes, that brings us to 8pm. He would have 47-39=8 more minutes to work. That brings us to 8:08pm.
The answer is 8:08pm.

Step-by-step explanation:
70% of something is 28.
We'll use the variable x to hold our value. 70% can be written as 0.7. Rewriting our equation, we get:
0.7 * x = 28.
Lets divide 0.7 over. Our new equation is:
x = 28 / 0.7.
You get that x = 40.
70% of 40 = 28.

1. slope = 12
y-intercept = 1/3
2.slope = 1/4
y-intercept= -12
3.slope = 3
y-intercept = 2
Step-by-step explanation:
When you get an equation for a graph, the co-efficient infront of the x (The number by the x) is the slope.
The equation for the y-intercept:
When solving for y-intercept, you replace y in the equation with 0 and make x the subject.
Example:
y = 12x - 4
0=12x - 4
-12x = -4
divide both sides by negative 12 since we want only positive x
[tex]\frac{-12x}{-12} =\frac{-4}{-12}[/tex]
x = [tex]\frac{1}{3}[/tex]
Therefore, the y-intercept = 1/3

Answer:
Mean = 33.7
Median = 34.5
Mode = 34
Range = 33
After adding 26....
mean decreases by 0.7
median decreases by 0.5
mode is 34
range is 33
Step-by-step explanation:
mean = sum of all the data values/number of data values
= (18 + 19 + 20 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/10
= 337/10
= 33.7
To find median arrange the values in increasing order, find the mid value
If the number of data points is even, find the average of the mid 2 data values
Arranging data values we get:
18, 19, 20, 34, 34, 35, 37, 42, 47, 51
Since there are 10 data values, take the average of the middle two:
(34 + 35)/2 = 34.5
The mode is the value that occurs most often. We see that there are two instances of 34 whereas the other values appear only once
Mode = 34
The range is highest - lowest = 51 - 18 = 33
After we add 26, we get the following data set arranged
18, 19, 20, 26, 34, 34, 35, 37, 42, 47, 51
we can calculate the stats using the same technique as above
We get the following values
mean = )(18 + 19 + 20 + 26 + 34 + 34 + 35 + 37 + 42 + 47 + 51)/11
= 33
median = 34
mode = 34
range = 51-18 = 33
To find the decrease in mean and median subtract from the first set of values

What is the height of a cylinder with a radius of 3 and a volume of 189?
Answers
Answer:
6.68 units (2 d.p.)
Step-by-step explanation:
The formula for the volume of a cylinder is:
[tex]\boxed{V=\pi r^2 h}[/tex]
where:
V is the volume.r is the radius of the circular base.h is the height.Given values:
V = 189 cubic unitsr = 3 unitsTo find the height of the cylinder, substitute the given values into the formula and solve for h:
[tex]\implies 189=\pi \cdot 3^2 \cdot h[/tex]
[tex]\implies 189=9\pi \cdot h[/tex]
[tex]\implies \dfrac{189}{9 \pi}=\dfrac{9\pi \cdot h}{9 \pi}[/tex]
[tex]\implies \dfrac{189}{9 \pi}=h[/tex]
[tex]\implies h=6.6845076...[/tex]
Therefore, the height of a cylinder with a radius of 3 units and a volume of 189 cubic units is 6.68 units (2 d.p.).

What's the area of the composite figure?
Answers
Answer:
422 cm²
Step-by-step explanation:
You want the surface area of the composite figure consisting of a 5 cm by 10 cm by 7 cm rectangular prism topped by a 3 cm by 4 cm rectangular prism extending 8 cm from the 7 by 10 cm surface.
Surface areaThe total surface area of the figure is the sum of the total surface area of the 5 by 10 by 7 cm yellow cuboid and the lateral area of the 4 by 3 by 8 cm purple cuboid.
A = 2(LW +H(L +W)) +Ph
where L, W, H are the dimensions of the yellow cuboid, P is the top perimeter of the purple cuboid, and h is its height.
ApplicationUsing the given dimensions, we find the area to be ...
A = 2(5·10 +7(5+10)) +2(3+4)·8 = 422 . . . . cm²
The surface area of the composite figure is 422 cm².
