Answer:
No
Step-by-step explanation:
Substitute (6, 10 ) into the left side of the inequality and compare value with right side.
8(6) + 2(10) = 48 + 20 = 68 > 2
Thus (6, 10 ) is not a solution of the inequality

Simplify (3−10)^2−(5−12)^2
Answer:
0
Step-by-step explanation:
(3−10)^2 − (5−12)^2
(3−10)^2 = 49
(5−12)^2 = 49
49 - 49 = 0
Answer: 0
Step-by-step explanation:
3-10= -7. -7^2=49
5-12=-7. -7^2=49
49-49=0

Solve the equation: 3x - x + 2 = 4(2x - 1) infinite solutions x = 1 x = -1 no solution
Answer:
[tex]x=1[/tex]
B
Step-by-step explanation:
So we have the equation:
[tex]3x-x+2=4(2x-1)[/tex]
Combine like terms on the left:
[tex]3x-x+2=4(2x-1)\\2x+2=4(2x-1)[/tex]
Distribute out the right:
[tex]2x+2=4(2x-1)\\2x+2=8x-4[/tex]
Subtract 2x from both sides. The left side cancels:
[tex](2x+2)-2x=(8x-4)-2x\\2=6x-4[/tex]
Add 4 to both sides. The right side cancels:
[tex]2+4=(6x-4)+4\\6=6x[/tex]
Divide each side by 6:
[tex](6)/6=(6x)/6\\x=1[/tex]
Therefore, the solution is: x=1.

Answer:
(D) C'D' and CD are equal in length
Step-by-step explanation:
When we reflect a line, nothing changes about it except it's position.
The line never gets dilated in any way.
This means that B and C must be incorrect, since they refer to dilating the line.
Now we can think about it. If we reflect a line across the y-axis, that means that the line will be parallel to the original line. This means A is false.
That leaves D.

4x - y = -7
-8x + 4y = 12
Elimination
Answer:
(x,y)=(-2,-1)
Step-by-step explanation:
4x - y = -7: 8x-2y=-14
8x-2y=-14
-8x + 4y = 12
add these two:
2y=-2
y=-1
plug in the y:
-8x-4=12
-8x=16
x=-2
A lending library has a fixed charge for the first three days and an additional charge for each day thereafter. Saritha paid ₹27 for a book kept for seven days, while Susy paid ₹21 for the book she kept for five days. Find the fixed charge and the charge for each extra day.
Answer: fixed charge = 15, extra day = 3
Step-by-step explanation:
Let x represent the charge for an extra day (after 3 days)
Let y represent the fixed charge (for first 3 days)
Equation 1: 7 days is 4 extra days --> 4x + y = 27
Equation 2: 5 days is 2 extra days --> 2x + y = 21
Multiply the second equation by -1 and add the two equations together:
4x + y = 27
-2x - y = -21
2x = 6
x = 3
Input x = 3 into either equation to solve for y:
2x + y = 21
2(3) + y = 21
y = 15
(-2)+6(-5)+9 find the sum
Answer: We should first use order of operations to multiply 6 and -5. Then we add and subtract from left to right.
Demo:
6 * (-5) = -30
Equation looks like: -2 - 30 + 9
-2 - 30 = -32
-32 + 9 = -23
-23 is the answer to this equation.
Marlon is bowling in a tournament and has the highest average after 5 games, with scores of 210, 225, 254, 231, and 280. In order to maintain this exact average, what must be Marlon’s score for his 6th game?
Answer:
240
Step-by-step explanation:
Right now, Marlon's average is (210 + 225 + 254 + 231 + 280) / 5 = 240. To maintain that average, the sum of Marlon's scores after 6 games must be 240 * 6. Currently, the sum of Marlon's scores is 240 * 5 so he must score a 240 * 6 - 240 * 5 = 240(6 - 5) = 240 * 1 = 240 for his last game.
The points S, T, U and V all lie on the same line segment, in that order, such that the
ratio of ST : TU: UV is equal to 6:2:3. If SV = 22, find TV.
==============================================
Explanation
Let x be some positive real number such that
ST = 6xTU = 2xUV = 3xleading to the ratio
ST:TU:UV = 6x:2x:3x = 6:2:3
Note how I effectively started with 6:2:3 and multiplied all parts of the ratio by x to get 6x:2x:3x
-----------------
The parts of the ratio add up to the longest segment SV
ST+TU+UV = SV
6x+2x+3x = 22
11x = 22
x = 22/11
x = 2
Therefore,
ST = 6x = 6*2 = 12TU = 2x = 2*2 = 4UV = 3x = 3*2 = 6Note how ST+TU+UV = 12+4+6 = 22, which is the length of SV. This helps confirm we have the correct x value.
-----------------
The last step is to find the length of TV
TV = TU+UV
TV = 4+6
TV = 10
Or you could do
ST + TV = SV
12+TV = 22
TV = 22-12
TV = 10

Renee wants to put a fence around her
square garden that has an area of
6,500 square feet. Determine the
perimeter of the garden to the nearest
tenth of a foot.
Answer:
320 "if rounded"
Step-by-step explanation: you find out what number times itself equals 6500 which is 80.623 "rounded to 80" then you add up all the sides "80+80+80+80" or "8x4" which would be 320 but you have to do nearest tenth so your answer would be 322.4.
hi help me (2·4)²= this is other (6:2)²+
Answer:
(2·4)² = 64 / (6*2)² = 144
Step-by-step explanation:
Follow PEMDAS :
Parenthesis first, so:
2 * 4
==> 8
Then Exponent:
8 ^2
==> 64
(2·4)² = 64
Do the same for (6:2)² :
Parenthesis first :
6 * 2
==> 12
Then Exponent:
12^2
==> 144
(6:2)² = 144
Answer:
1. 64 is the answer.2. 144 is the answerStep-by-step explanation:
First, multiply the numbers inside the parenthesis. So
1. 2*4 = 8
2. 6*2 = 12
Next, Use the exponents
1. 8^2
2. 12^2
Finally, solve using exponents.
1. 8^2 = 64
2. 12^2 = 144
So 64 and 144 is the answer.

HI
Answer:
[tex]B = \frac{3}{2} * 21,356[/tex]
Step-by-step explanation:
Given
Represent Jimmy with J and Bob with B
[tex]J = 21,356[/tex]
[tex]B = 1\frac{1}{2} * J[/tex]
Required
Determine the expression for B
[tex]B = 1\frac{1}{2} * J[/tex]
Substitute 21,356 for J
[tex]B = 1\frac{1}{2} * 21,356[/tex]
Convert Mixed fraction to improper
[tex]B = \frac{3}{2} * 21,356[/tex]
The above is an expression for B
Solving further, we have
[tex]B = \frac{3 * 21,356}{2}[/tex]
[tex]B = \frac{64068}{2}[/tex]
[tex]B = 32034[/tex]
What are the major arcs of o0 that contain point B?
Answer:
Option (C)
Step-by-step explanation:
By the definition of a major arc - any arc of a circle which measures more than 180° is the major arc.
In the given circle, AC and BD are the two chords.
And arcs measuring more than 180° are,
[tex](\widehat{BCA}, \widehat{CDB}, \widehat{ABD},\widehat{DAC},\widehat{DBC},\widehat{ACD})[/tex]
Therefore, the arcs given in Option (C) will be the major arcs of the circle O.
Option (C) will be the correct option.
I need help please !!
Answer:y=28
Step-by-step explanation:
all triangles add up to 180 and this triangle is an isosceles triangle so 34 should be equal to x-5 meaning that two of the angles are 34 degrees and you just need to subtract 34(2) from 180 which is 180-68 to give you 112. Then since this is the value of 4 times y, just divide 112 by four to isolate the variable and you get 28.

Two people share $52.20 in the ratio 4:5. How much does each person receive?
Answer:
$23.20 and $29
Step-by-step explanation:
We can set up a simple equation to solve this problem.
4x + 5x = 52.2
9x = 52.2
x = 5.8
To find out how much each person received, we multiply 5.8 with the ratio numbers 4 and 5. That gives us $23.20 and $29, respectively.
