Is this equation infinity many solution 5c+9=5c-12

Answer: No solution

When an equation has infinitely many solutions, it is the exact same equation on both sides. For example, for this to be infinitely many, it would have to be:

5c+9=5x+9

This would be infinitely many, because it would be the same line plotted twice, so it would have an infinite amount of intersecting points.

This also cannot be one solution, because they have the same slope. When an equation has the same slope, it can either be infinitely many solutions or one solution. We already explained why this is not infinitely many, but it is also not one solution. If plotted, these points could never intersect. For this to be one solution, it would have to be:

5c+9=4c-12

This means the equation has no solution. It will never intersect. Let’s prove this by solving:

5c+9=5c-12

*subtract 5c on both sides*

9=-12

Since this is not true and 9 does not equal -12, there is no solution

Answer:

The answer is no solution.

Step-by-step explanation: First, you would add + 12 to both sides of the equation so that you would have 5c + 21 = 5c. Then, you would subtract 5c from both sides of the equation. This would leave you with 21 = 0. Since this is not true, the equation would have no solution.

An = a1 + (n − 1)d<br> Find the 31st term of the sequence -22, -19, -16, -13,...
JulsSmile [24]

Answer:

68.

Step-by-step explanation:

The common difference d = -19 - (-22) = 3

So the 31st term =

a31 =  -22 + (31-1)3

= -22 + 90

= 90 - 22

= 68.

A computer company has a special going in which all customers receive a free monitor and scanner with the purchase of a new comp
kipiarov [429]

Answer:

2160

Step-by-step explanation:

Given : At a computer​ store, a customer is considering 10 different​ computers, 6 different​ monitors, 9 different printers and 4 different scanners. We assume that each of the components is compatible with one another and that one of each is to be​ selected. then by Fundamental counting principle , the number of different computer systems possible is given by :-

10x6x9x4= 2160

Hence, the number of different computer systems possible= 2160The Fundamental Counting Principle is a technique in Mathematics to calculate the number of possible outcomes by multiplying the events together .

O is the centre of the circle, EF is a tangent, angle BCE=28 degrees, angle ACD=31 degrees.
Yuki888 [10]

Answer:

a. 28˚

b. 76˚

c. 104˚

d. 56˚

Step-by-step explanation

a. because angle between tangent and chord is equal to the angle(s) in alternate segment.

b. because angles in triangles add up to 180˚, 180-28=152 and because isosceles triangle, 152/2=76˚

c. because angles in triangles add up to 180˚ and opposite angles in a cyclic quadrilateral add up to 180˚, 31+76=107, 180-107=73, 73-28=45, angles in triangle so 180-(31+45)=104˚

d. 28*2=56˚ because angles at circumference are half angles at centre
