Does the following graph represent a function, Yes or No
Answer:
no
Step-by-step explanation:
Use the vertical line test to determine if it is a function
Since a vertical line touches more than one point on the graph, it is not a function

What is the equation of a line, in general form, that passes through point (1, -2) and has a slope of 1/3
O 3x-y-7=0
x - 3y + 7 = 0
Ox-3y - 7 = 0
O-X + 3y - 7 = 0
Answer:
x- 3y -7 =0
Step-by-step explanation:
Point slope form is
y-y1 = m(x-x1) where m is the slope
y - -2 = 1/3 (x-1)
y+2 = 1/3 (x-1)
Multiply each side by 3 to get rid of the fraction
3y +6 = x-1
Subtract 3x from each side
6 = x-3y -1
Subtract 6 from each side
0=x -3y -7
x- 3y -7 =0
The general form is
Ax +by +C = 0 where A , B C are integers and A > 0
Answer:
x-3y-7=0
Step-by-step explanation:
[tex]y=\frac{1}{3} x+c\\-2=\frac{1}{3}\times 1+c\\c=-\frac{7}{3} \\y=\frac{1}{3} x-\frac{7}{3}\\\\3y=x-7, 0=x-3y-7[/tex]

Which graph is correct?
Let's first take a look at our x here. --- (x + 2)^2
Because we are adding a two to our x, this means that we are shifting our graph 2 to the left. Remember that with functions, it's always the opposite!
There is nothing attached to the y, so we are not moving our function up or down.
And then the radius of our circle. Remember that the equation requires us to square this value (... = r^2), so we need to take the square root of 4. The square root of 4 is 2.
With this information, let's now look at our options.
Option A - INCORRECT, the radius is too large
Option B - INCORRECT, this was shifted 2 units to the right
Option C - INCORRECT, the radius is too large
Option D - CORRECT, the radius is 2 and the circle was shifted 2 units to the left
Hope this helps!! :)
Answer:
D
Step-by-step explanation:
The equation for a circle is
(x-h)^2 + (y-k)^2 = r^2
where (h,k) is the center and r is the radius
(x+2)^2 + (y)^2 = 4
Rewritng
(x- -2)^2 + (y-0)^2 = 2^2
The center is at ( -2,0) and the radius is 2
C and D are the only circles with a center at (-2,0)
B,D are the only circles with radius 2

1) Fidel had 12 boxes of paper plates. Each box contains 36 paper plates. He used 173 paper plates for the birthday party of his son. How many paper plates were left?
1 box= 36 paper plates
12 boxes = 12× 36 paper plates
= 432 paper plates
He used 173 paper plates for the birthday party of his son
No. of paper plates were left = 432-173 = 259

How many ways can a supermarket chain select 4 out of 12 possible sites for construction of new supermarkets?
Answer:
6
Step-by-step explanation:
Answer:
I am pretty sure it's 495
Step-by-step explanation:
The context of this problem makes me think that the order in which the sites are in does not matter
if that's the case we can solve this using combinations
the combinations formula is as follows:
ACB= [tex]\frac{A!}{(A-B)!*B!}[/tex]
so 12C4= [tex]\frac{12!}{(12-4)!*4!}=495[/tex]

Answer:
30m x 40m
Step-by-step explanation:
The diagram is 15cm x 20cm
since 1cm = 2m
the backyard measures
30m x 40m
Answer: The backyard is 30 meters by 40 meters
30 meters = horizontal dimension
40 meters = vertical dimension
===========================================================
Explanation:
The pool on paper is 7.5 units across horizontally. Applying the scale factor, we can see that it corresponds to 7.5*2 = 15 meters
The 20 meter portion is vertical. On paper, we see that it's 10 units tall. So the "times 2" operation applies to jump from 10 cm to 20 meters
Or you could note that the ratio 1 cm : 2 m scales up to 10 cm : 20 m after multiplying both parts by 10.
-----------------
With that in mind, all we need to do really is count the number of squares across the top and along the left side. Across the top, we have 15 squares. That 15 cm corresponds to 15*2 = 30 meters in length.
Along the left side, the figure is 20 cm tall. So that corresponds to 20*2 = 40 meters.
The backyard is 30 meters by 40 meters. This includes the backyard, shed, and other features in the diagram. The entire backyard is 30*20 = 600 square meters. If you wanted to know the area of the grass only, then you'd subtract off the areas of the pool, shed, etc.
-----------------
Your teacher mentions that the pool is similar to the backyard overall. Since we're in a geometry setting, the word "similar" is very specific of course.
We can match up the corresponding lengths to form a proportion like so
(large horizontal)/(small horizontal) = (large vertical)/(small vertical)
30/15 = 40/20
2 = 2
So that confirms we have similar figures, at least in terms of the sides being proportional. Everything being a rectangle helps show that all angles are the same.
4+9 because i need to waste my points
Answer:
ummmmm i think apple?
Step-by-step explanation:
because if 4 equals green and you put the square root of branch in there you will get branch×apple tree+water=apple my bad its green apple
i did it wrong i just redid the question and found the right answer. so if you put branch×square root of 9 apples+apple tree=9 apples right? well yes but if you add branch+square root of 4 more apples you will get in total 13 apples.

hi I am sorry I wish I could help
Answer:
x ≈ 6.2
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
x² + 17.1² = 18.2²
x² + 292.41 = 331.24 ( subtract 292.41 from both sides )
x² = 38.83 ( take the square root of both sides )
x = [tex]\sqrt{38.83}[/tex] ≈ 6.2 ( to the nearest tenth )

HELP? NEED HELP WITH SECOND ONE!!!
Please help me with this im pretty confused ?
Answer:
a=6
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
a^2 + 8^2 = 10^2
a^2 + 64= 100
a^2 +64-64 = 100-64
a^2 = 36
Take the square root of each side
sqrt(a^2) = sqrt(36)
a = 6
Answer:
a = 6
The length of side a is 6.Step-by-step explanation:
According to the question,
Using Pythagorean theorem
( a )² + ( b )² = ( c )²
Where, a and b are the base and c is the length of hypotenuse.( a )² + ( 8 )² = ( 10 )²
evaluate the exponent
a ² + 64 = 100
subtract 64 from each side
a ² + 64 - 64 = 100 - 64
a ² = 36
Take the square root of each side
√a² = √36
a = 6
What is the value of xin this triangle?
Enter your answer as a decimal. Round only your final answer to the
nearest hundredth.
32 58
Answer:
33.48
Step-by-step explanation:
Find the diagram attached
Opposite = 32
Hypotnuse = 58
Sin theta = opposite/hypotenuse
Sin theta = 32/58
Sin theta = 0.5517
theta = arcsin(0.5517)
theta = 33.48
Hence the value of x to the nearest tenth is 33.48
The area of a circle is 81π in². What is the circumference, in inches? Express your answer in terms of (Pie)
Answer:
18 pi inches
Step-by-step explanation:
The area of a circle is
A = pi r^2
81 pi = pi r^2
81 = r^2
Taking the square root of each side
9 = r
We can now find the circumference
C = 2 * pi *r
C =2 * pi *9
C = 18 pi
