How many and what type of solutions does the equation have?

Mathematics
1 answer:
ella [17]3 years ago
7 0

Answer: C

Step-by-step explanation:

Simplify to 4x^2 + 12x + 5 = 0 so that all the terms are on one side.

Do a part of the quadratic formula to see.

You only need to do the -b^2-4ac part. If it is negative, that means there are irrational solutions. If it is positive, it has two solutions. If it is 0, it has 1 solution.

12^2-4(4)(5) = 64

It is positive so it has two solutions.

Which equation matches the sentence? Column A Column B
ioda
I will put an equation to the corresponding number.

1) Seven more than 2 times a number is 23 => 2n + 7 = 23
2) The difference of 2 times a number and 7 is 23 => 2n - 7 = 23
3) The sum of 7 times a number and 2 is 23 => 7n + 2 = 23
4) Seven less than 2 times a number is 23 => 2n - 7 = 23

Based on the choices. The equation that matches sentences 2 & 4 is letter b. 2n - 7 = 23

Though both sentences are structured differently and used different terms, they both refer to subtraction of 7 from the product of 2 and n to get the difference of 23.

What is 8/10 divided by 1 5/6
sveta [45]
1st change 1 5/6 into a mixed number:
1 5/6 = 11/6

New problem:
8/10 divided by 11/6

to divide fractions you turn the 1st fraction upside down and then change the division sign to a multiplication sign:

8/10 / 11/6
10/8 * 11/6
=55/24 or 1 7/24
