2. How many solutions to the equation 2x +2 = 2(x+3)
O 1 solution
O Infinitely many solutions
O No solution
Answers
Answer:
O No solution
Step-by-step explanation:
2x +2 = 2(x+3)
Distributer the 2 on the right side.
2x + 2 = 2x + 6
Subtract 2x from both sides.
2 = 6
2 = 6 is a false statement.
Since we did two legal steps to solve the equation, and we ended up with a false statement, that means this equation has no solution.
Answer: O No solution

If there are twice the number of nickels”x” then there are quarters”y” and the amount of money is 1.75. Find the number of each coin.
Answers
Answer:
let the two number be x and y then,
x+y=12
x-y=-4

2x=8
or, x = 4 put the value of x in first equation
4+y= 12
or, y=12-4

Brainliest PleaseYour friend says that the table represents an exponential function because y is multiplied by a constant factor. Is your friend correct? Explain.
A.Yes. Because y is multiplied by a constant factor, the function is exponential.
B.Yes. Because y increases by greater amounts as x increases, the function is exponential.
C.No; Because y is multiplied by a constant factor, the function is not exponential.
D. No; Because x increases by different amounts, the function is not exponential.
x: 0,1,3,6
y: 2,10,50,250
Answers
Answer:
C.No; Because y is multiplied by a constant factor, the function is not exponential.
Step-by-step explanation:
For a set of number to be exponential, there is need for it to show a logical increase of a given time frame when the set of number is multiplied by a constant factor. In the table given, though the Y function is multiplied by a constant factor, the increase of the function is irregular so therefore cannot be said to be exponential.

Find a positive and a negative coterminal angle for 50 degrees
Answers
Answer: To find the coterminal angle of a 50° angle, add 360°. It would follow that 50°+360°=410°. A 410° angle is illustrated below. From the graphical representation of the angle, we can conclude that these two angles do indeed share the same terminal side, meaning they are coterminal.
Step-by-step explanation:
The positive and negative coterminal angle for 50 degrees are 410 degrees and -310 degrees respectively.
What is coterminal angle?'Coterminal angles are the angles that have the same initial side and share the terminal sides.'
According to the given problem,
To find positive coterminal angle, we have to add 360 degrees to it,
⇒ 50 + 360 = 410 degrees.
To find negative co terminal angle, we have to subtract 360 degrees from it,
⇒ 50 - 360 = -310 degrees.
Hence, we can conclude that 410 degrees and -310 degrees are the coterminal angle for 50 degrees.

5 STARS 20 foot ladder is leaning against the side of a building the bottom of the ladder is 4 feet from the wall the bottom of the ladder is 4 feet from the wall how many feet above the ground does the ladder touch the wall
Answers
Answer:
400
The ladder is the hypotenuse of a right triangle. The 2 feet from the wall on the ground is one side, the distance up the wall is another side.
In a right triangle, the square of the hypotenuse is the sum of the squares of the other two sides. This is called the Pythagorean Theorem. In equation form:
c^2 = a^2 + b^2
Substitute the known values:
20^2 = 2^2 + b^2
Square the numbers:
400 = 4 + b^2
Subtract 4 from both sides:
b^2 = 400 - 4 = 396
Take the square root:
b = sqrt(396) = 19.9 (rounded) feet
Check:
20^2 ?= 2^2 + 19.9^2
400 ?= 4 + 396.01
400 ?= 400.01 (off just a bit due to rounding)

Answers
Answer:
i think itz C
Step-by-step explanation:
The required ordered pair is (5,0) in the solution set of the given inequality 3x - 5y ≥ 12. The correct answer would be option (B).
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
The given graph of 3x - 5y = 12 is shown on the grid.
To find the solution set of 3x - 5y ≥ 12, we need to shade the region of line 3x - 5y = 12 since it represents all the points that make the inequality true.
When all the given points are drawn in the graph, then we get the ordered pair (5,0) in the solution set of the given inequality.
Thus, the required ordered pair is (5,0) in the solution set of the given inequality 3x - 5y ≥ 12.
Therefore, the correct answer would be an option (B).

Please Answer as soon as you can I am giving 50 points!
Answers
Answer:
Step-by-step explanation:
13.98
The altitude of Carlita's kite to the nearest hundredth should be considered as the 13.98 yards when she uses 25 yards of string at an angle of elevation of 56.
Calculation of the altitude of Carlita's kite:Since she uses 25 yards of string at an angle of elevation of 56°
So we know that
cos 56 degrees = 0.5592
Now the altitude is
= (25) (0.5592)
= 13.98 yards
We basically multiplied these two so that the altitude should come.
hence, the first option is correct.
