Step-by-step explanation:
[tex] \frac{3}{4} = \frac{4 - 1}{x - 7} \\ \\ \frac{\cancel 3}{4} = \frac{\cancel 3}{x - 7} \\ \\ \frac{1}{4} = \frac{1}{x - 7} \\ \\ 4 = x - 7 \\ \\ 4 + 7 = x \\ \\ 11 = x \\ \\ x = 11[/tex]

Which system of equations is equivalent to the system of equations shown? 2x + 5y = -2 4x + 7y = 8
Answer:
x=9, y=-4. (9, -4).
Step-by-step explanation:
2x+5y=-2
4x+7y=8
--------------
-2(2x+5y)=-2(-2)
4x+7y=8
---------------------
-4x-10y=4
4x+7y=8
--------------
-3y=12
y=12/-3
y=-4
2x+5(-4)=-2
2x-20=-2
2x=-2+20
2x=18
x=18/2
x=9
A triangle is formed by A(0,1), B(1,0), and C(2,4). If the triangle is rotated 90 degrees counterclockwise, which algebraic representation would be used? Select one:
0 (2, y) + (-1, - y)
O (, y) + (y, - 2)
0 (2,y) → ( - 1, y)
0 (2,y) → ( - y, z)
Answer:
[tex](x,y) \to (-y,x)[/tex]
Step-by-step explanation:
Given
[tex]A = (0,1)[/tex]
[tex]B = (1,0)[/tex]
[tex]C = (2,4)[/tex]
90 degrees counterclockwise rotation
Required
The algebraic representation
Let the coordinate point be [tex](x,y)[/tex]
The rule of 90 degrees counterclockwise rotation is:
[tex](x,y) \to (-y,x)[/tex]
So, we have:
[tex]A = (0,1)[/tex] [tex]\to (-1,0)[/tex]
[tex]B = (1,0)[/tex] [tex]\to (0,1)[/tex]
[tex]C = (2,4)[/tex] [tex]\to (-4,2)[/tex]

$10,000 at an annual rate of 7%, compounded semi-annually, for 2 years
Use the compound interest table to find each balance
Will give brainliest 5 stars and thanks
Answer:
[tex]\$13,107.96[/tex]
Step-by-step explanation:
Since interest is compounded semi-annually (half a year or 6 months), in a spawn of 2 years, the interest will have been compounded 4 times. As given in the problem, each time the interest is compounded, the new balance will be 107% or 1.07 times the amount of the old balance.
Therefore, we can set up the following equation to find the new balance after 2 years:
[tex]\text{New balanace}=10,000\text{ (old balance)}\cdot 1.07\cdot 1.07\cdot 1.07\cdot 1.07,\\\text{New balanace}=10,000\cdot 1.07^4=\boxed{\$13,107.96}[/tex]
Juan went to the store to buy a plant for his mother, but forgot to ask which kind to get. Out of 30 plants, eighteen of them are a kind that his mother would want. If Juan chooses one randomly, what is the probability that he will choose a kind that his mother would want?
Answer:
Probability [Randomly choose plant Juan's mother want] = 3 / 5
Step-by-step explanation:
Given:
Total number of plant in store = 30 plants
Number of plant kind Juan's mother want = 18
Find:
Probability [Randomly choose plant Juan's mother want]
Computation:
Probability of an event = Number of favorable outcome / Total number of outcomes
Probability [Randomly choose plant Juan's mother want] = Number of plant kind Juan's mother want / Total number of plant in store
Probability [Randomly choose plant Juan's mother want] = 18 / 30
Probability [Randomly choose plant Juan's mother want] = 3 / 5
Which equation can be used to solve for the value of x?
option : c. 2x + 15 = 145
cuz, the angles are vertical opposite angles
Answer:
2x + 15 = 145
Step-by-step explanation:
vertical angles are congruent
=> (2x + 15)° = 145°

Which operation would be last when solving the inequality -5x + 9 < -6
Answer: divding both sides by -5
Step-by-step explanation:
Subtract 9 from both sides.
−5x+9−9<−6−9
−5x<−15
Step 2: Divide both sides by -5.
−5x/−5<−15/−5
x>3
Identify the volume of the hemisphere in terms of π. HELP ME PLEASE!!! THE RED IS THE ONE I GOT WRONG!
Answer:
6174π
Step-by-step explanation:
The equation for a whole sphere is 4/3 π(r)³
Given the diameter of 42, we can conclude that the radius would be 21
Next, we would plug in these variables and get 4/3 π(21)³
Simplify all of this down and you would get 12348π
Keep in mind that we are working with a hemisphere. That means that we need to take half of 12348π
Divide that by 2 and you get 6174π
Hope this helps! :)
PLZ HELP I BEG UU !! 50 POINTS AND BRANLIEST>
Answer: 102.5
Step-by-step explanation:
Area of triangle: 8*6=48, 48/2=24
Area of semicircle: 2pir^2=2pi(5)^2=157
Because its semi circle it is 157/2 which equals 78.5
Total area:24+78.5=102.5
Answer:
102.5
Step-by-step explanation:
Semi circle = 78.54 ≈ 78.5
Using formula A = πr²
Area triangle = 24
Using formula A = 1/2(bh)
Sum = 78.5 + 24 = 102.5

Answer:
Median:9.5
Mean:16.5
Step-by-step explanation:
Median: Put them in order, find the middle, since there is two median we add them together, then divide them by 2 and there's your answer.
Mean: Add the numbers: 0+ 6+ 13+47= 66
Divide by how many numbers (there are 4 numbers): 66/ 4= 8
