The discriminant of a quadratic equation is 16. Which number represents the number of real solutions to the equation?
0
3
Answer:
The
number 2
Step-by-step explanation:
What we need here is just the sign of the discriminant
From the question in this case, the discriminant is positive
Thus, whenever we have a positive discriminant, then the number of real solution is 2 and these two are distinct (different from one another).

Answer:
We conclude that
[tex]4\frac{2}{3}[/tex] > [tex]\sqrt{21}[/tex]
Step-by-step explanation:
Given
[tex]\sqrt{21}[/tex][tex]4\frac{2}{3}[/tex]as
[tex]\:\sqrt{21}=4.58[/tex]
and
[tex]4\frac{2}{3}[/tex]
Convert mixed numbers to improper fraction:
[tex]a\frac{b}{c}=\frac{a\cdot \:c+b}{c}[/tex]
so
[tex]4\frac{2}{3}=\frac{4\cdot 3+2}{3}=\frac{14}{3}=4.67[/tex]
Thus,
[tex]\:\sqrt{21}=4.58[/tex]
[tex]4\frac{2}{3}=4.67[/tex]
as
4.67 > 4.58
so
[tex]4\frac{2}{3}[/tex] > [tex]\sqrt{21}[/tex]
Hence, we conclude that
[tex]4\frac{2}{3}[/tex] > [tex]\sqrt{21}[/tex]
If the measure of each base angle of an isosceles triangle is represented by x, then the vertex angles is represented by
Answer:
vertex angle = 180° - 2x
Step-by-step explanation:
Since, the measure of each base angle of an isosceles triangle is represented by x.
So, by interior angle sum postulate of a triangle, we have:
x + x + vertex angle = 180°
2x + vertex angle = 180°
vertex angle = 180° - 2x
So, the vertex angle is represented by (180° - 2x).

If your good at math plz help me
Answer:
If your good at math plz help me
i think this is the answer, hope A(-3)=n-5
==================================================
Work Shown:
[tex]a_1 = -3 = \text{ first term}\\\\d = -5 = \text{ common difference}\\\\a_n = a_1 + d(n-1) = \text{ nth term}\\\\a_n = -3 + (-5)(n-1)\\\\a_n = -3 -5n + 5\\\\a_n = -5n + 2\\\\[/tex]
The common difference is due to us adding -5 to each term to get the next one. Example: -3+(-5) = -8, or -8+(-5) = -13.
--------------------
As a way to check if we have the correct nth term formula, plug in values of n to see if we get the correct sequence value
For instance, if n = 1, then
[tex]a_n = -5n+2\\\\a_1 = -5(1)+2\\\\a_1 = -5+2\\\\a_1 = -3\\\\[/tex]
Which matches with the first term given to us.
Or if n = 2, then,
[tex]a_n = -5n+2\\\\a_2 = -5(2)+2\\\\a_2 = -10+2\\\\a_2 = -8\\\\[/tex]
That matches the second term given to us. I'll let you check the others.

if 50% is 10 what is 25%
Step-by-step explanation:. The first says “I know that 10 is one-tenth of 100. I will therefore divide 50 by 10. The answer is 5”.
This is fine when the numbers are relatively simple. But suppose the numbers are more complicated.
What is 22% of 46?
Now it’s much less straightforward. You can’t just work out what 22% is, expressed as a fraction, and anyway, it’s not a simple fraction.
Instead, you have to divide 46 into 100 equal parts, and work out what 22 of them would be when added together.
So: 46 ÷ 100 = 0.46 [remember, when you divide by 100, you move the decimal point two places to the left].
0.46 × 22 = 10.12
Answer: 22% of 46 is 10.12.

How do you find a unit rate
Answer:
Divide the numerator and denominator
Step-by-step explanation:
A unit rate is a ratio between two different units with a denominator of 1. To calculate the unit rate, divide the numerator by the denominator. The resulting decimal number is the unit rate. The unit price is a type of ratio where the numerator is the price and the denominator is the quantity of a good or product.
What are the like terms in the expression below?
3x + 8 + 3y + 8x
Answer:
3x and 8x are like terms.
Step-by-step explanation:
Like terms are the terms that share the same variables. They do not have to share the same coefficients - or, in other words - the numbers in front of the variable do not have to be the same. Only the variable has to match.
So, looking at the expression, the only two terms that have the same variable are 8x and 3x, which both have the variable x. Therefore, 3x and 8x are like terms.
