Answer:
(0,7) and (0, 7/2).
Step-by-step explanation:
lets start with putting 0 instead of x to get the y-intercept:
x = 0, y= -7
and then we put 0 instead of y to get the x-intercept:
Y = 0, 0=2x-7, x = 7/2
we can put the points (0,7) and (0, 7/2).

If ab = 9 and a² + b² = 81, then (a+b)² = ?
Answers
Answer:
99
Step-by-step explanation:
Through some clever algebra, we can combine our first two equations using the fact that
[tex](a+b)^2=a^2+2ab+b^2[/tex]
We have the a² and the b² in the equation [tex]a^2+b^2=81[/tex], and we almost have a 2ab in the equation [tex]ab=9[/tex]. To get that 2ab, we can simply double both sides of the first equation to get [tex]2ab=18[/tex]. From there, we'll add the first two equations together, giving us the summed equation
[tex]a^2+b^2+2ab=81+18\\a^2+2ab+b^2=99[/tex]
And since [tex](a+b)^2=a^2+2ab+b^2[/tex], we can equivalently say that
[tex](a+b)^2=99[/tex]

m<KJL=22°
Step-by-step explanation:
6x=9x-27
27=3x
x=9
9(9)-27=54
BC=54
4x+6=3x+10
x=4
4(4)+6=22
m<KJL=22°
Answer:
BC = 54 unitsm∠KJL = 22°Step-by-step explanation:
BD is the perpendicular bisector of AC because AD = DC and DB⊥AC, therefore AB = BC
6x = 9x - 279x - 6x = 273x = 27x = 9BC = 9x - 27 = 9*9 - 27 = 81 - 27 = 54
-----------------------
JL is angle bisector of KJM, because KL = ML and KL⊥JK & ML⊥JM, therefore
m∠KJL = m∠MJL4x + 6 = 3x + 104x - 3x = 10 - 6x = 4m∠KJL = 4*4° + 6 = 22°

A large sphere at an amusement park is 165 feet in diameter which of the following is closest to the volume in cubic feet of the sphere?
Answers
Answer:
Below.
Step-by-step explanation:
The volume of a sphere = 4/3 π r^3 where r is the radius.
Here the radius = 1/2 * 165 = 82.5 ft.
So the volume = 4/3 π (82.5)^3
= 2,352,071.15 ft^3.
The volume of the sphere with the given diameter is closest to 2,351,000.
What is Sphere?A sphere is a three dimensional figure which consists of set of all the points which are at an equal distance from a point called the center of the sphere.
Given that,
Diameter of the given sphere in the amusement park = 165 feet
Radius is half the diameter.
Radius of the sphere = 165/2 = 82.5 feet
Volume of the sphere = [tex]\frac{4}{3}[/tex] π r³
= [tex]\frac{4}{3}[/tex] π (82.5)³
= 748687.5π
= 2352071.15 feet³
The most closest one in the option is 2,351,000.
Hence the volume of the sphere is closest to 2,351,000.

[tex]\Huge\boxed{76}[/tex]
Step-by-step explanation:
Hello There!
The first thing we want to do is find the proportional relationship between to two triangles
The smaller triangles longest side is 18
Given the longest side of the similar triangle we can divide the longest side of the preimage by the longest side of the similar triangle
So the proportional relationship would be
36/18 or 2
Our next step is to find the the sides of the similar triangle
To do so we multiply the sides of the preimage by 2 (because 2 is the proportional relationship between the two triangles)
12x2=24
8x2=16
and we already know that the longest side measures 36
Now we can find the perimeter by adding all of the side lengths
36+24+16 = 76
So we can conclude that the perimeter of the dilated image is 76
The perimeter of the dilated triangle is 81.

Answers
The number of yellow counters in the bag Jamal has got for this case is obtained being 96
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
Given that:
The bag initially had 36% of red counters and rest of the counters being yellow in color.Later was added 50 blue counters.The number of blue counter in the bag is 25% of all the counters in the bag.Let the initial number of counters in the bag be 'x'
Then, 36% of x is:
[tex]\text{Number of red counters} = \dfrac{x}{100} \times 36 = 0.36 \times x[/tex]
Rest of them are yellow, so we get:
[tex]\text{Number of yellow counters} = x - \dfrac{x}{100} \times 36 = x(1-0.36) = 0.64 \times x[/tex]
Now, adding 50 blue counters make:
Total count of counters in bag = [tex]x + 50[/tex]
25% of this count is blue, and we know its 50. Thus, we get:
25% of (x+50) = 50
or
[tex]\dfrac{x+50}{100} \times 25 =50\\\\x+50 = 4 \times 50\\\\x = 200-50 = 150[/tex]
Thus, there were 150 coutners in the bag, initially.
The number of yellow counters is:
[tex]\text{Number of yellow counters} = 0.64 \times x = 0.64 \times 150 = 96[/tex]
Thus, the number of yellow counters in the bag Jamal has got for this case is obtained being 96

A game of "Doubles-Doubles" is played with two dice. Whenever a player rolls two dice and both die show the same number, the roll counts as a double. If a player rolls doubles, the player earns 3 points and gets another roll. If the player rolls doubles again, the player earns 9 more points. Whenever the player rolls the dice and does not roll a double, they lose points. How many points should the player lose for not rolling doubles in order to make this a fair game? Now O 1 Mark this and return Save and Exit Next
Answers
Answer:
27/35
Step-by-step explanation:
just did it on edg
The number of points that should the player lose for not rolling doubles in order to make this a fair game is [tex]27\div 35[/tex]
Calculation of the number of points:Since If a player rolls doubles, the player earns 3 points and gets another roll. If the player rolls doubles again, the player earns 9 more points.
So here the probabilities could be
one double= [tex]5\div 36[/tex]
two doubles [tex]=1\div 36[/tex]
no doubles =[tex]1\div6[/tex]
Now
here we assume the number of points be x
So,
[tex]12\div 36 + 5[(3-x)\div 36] - (5)(x\div 6) = 0\\\\x=27\div 35[/tex]
Therefore, The number of points that should the player lose for not rolling doubles in order to make this a fair game is [tex]27\div 35[/tex]

Solve for x and y in the parallelogram below.
Answers
Answer:
[tex]\Huge\boxed{x=74}\\\Huge\boxed{y=106}[/tex]
Step-by-step explanation:
Hello There!
In parallelograms opposite sides are congruent and opposite angles are congruent
In the parallelogram shown the angle with a measure of 72 degrees and the angle labeled x are opposite angles therefore is one of the angles equals 72 degrees then so does the other one so x = 72
because a parallelograms sides are parallel the angles that are on the same side are supplementary angles meaning that the sum of the two angles is 180
so basically what I'm saying is that the angle measure 74 and the angle labeled y have a sum of 180
so to find angle y we subtract the given angle from 180
180-74=106 so we can conclude that y = 106
