Consider the equation 5x^2-10x+c=0. What values of c result in the equation having a complex solutions? Represent your answer on the number line
Answer:
When we have a quadratic equation:
a*x^2 + b*x + c = 0
There is something called the determinant, and this is:
D = b^2 - 4*a*c
If D < 0, then the we will have complex solutions.
In our case, we have
5*x^2 - 10*x + c = 0
Then the determinant is:
D = (-10)^2 - 4*5*c = 100 - 4*5*c
And we want this to be smaller than zero, then let's find the value of c such that the determinant is exactly zero:
D = 0 = 100 - 4*5*c
4*5*c = 100
20*c = 100
c = 100/20 = 5
As c is multiplicating the negative term in the equation, if c increases, then we will have that D < 0.
This means that c must be larger than 5 if we want to have complex solutions,
c > 5.
I can not represent this in your number line, but this would be represented with a white dot in the five, that extends infinitely to the right, something like the image below:
Draw a model to help solve 5/6 + 1/4. write ur answer as a mixed number.
The required simplified solution of the given expression in the form of a mixed number is 1 1/12.
Given that,
To determine the solution of expression 5/6 + 1/4. in the form of a mixed number.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
here,
= 5 / 6 + 1 / 4
= [ 5×4 + 1×6 ] / [6×4]
= 26 / 24
= 13 / 12
= 1 + 1 /12 or 1 1/12
Thus, the required simplified solution of the given expression in the form of a mixed number is 1 1/12.

Split 18 into the ratio 1:2
Answer:
6 : 12
Step-by-step explanation:
sum the parts of the ratio, 1 + 2 = 3 parts
Divide by 3 to find the value of one part of the ratio
18 ÷ 3 = 6 ← value of 1 part of the ratio, thus
2 parts = 2 × 6 = 12
1 : 2 = 6 : 12
The number 18 splitted into a ratio of 1 : 2 is 12 and 6.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Slitting in the ratio 1 : 2 can be done in this manner,
{1/(1+2)]×18.
= (1/3)×18.
= 6.
And,
{2/(1+2)]×18.
(2/3)×18.
= 12.

Adjust the window so you can find all of the points of intersection for the system of equations. What are the roots of the original polynomial equation? Check all that apply. –6 0 6 –4 3 8
Answer:
Your answer would be 6, -4, and 3
Step-by-step explanation:
The roots of the original polynomial equation are 6, -4 and 3
How to determine the root of the polynomial?The polynomial equation is given as:
P(x) = (x - 6)(x + 4)(x - 3)
Set the polynomial to 0
(x - 6)(x + 4)(x - 3) = 0
Split the equation
(x - 6) = 0, (x + 4) = 0 and (x - 3) = 0
Solve for x in each split
x = 6, x = -4 and x = 3
Hence, the roots of the original polynomial equation are 6, -4 and 3

Alonso brings \$21$21dollar sign, 21 to the market to buy eggs and avocados. He gets eggs that cost \$2.50$2.50dollar sign, 2, point, 50. Then, he notices that the store only sells avocados in bags of 333 for \$5$5dollar sign, 5. He wants to buy as many avocados as he can with his remaining money. Let BBB represent the number of bags of avocados that Alonso buys.
Answer:
B ≤ 3.7
Step-by-step explanation:
Total money with Alonso = $21
Cost of Eggs = $2.50
Cost of Avocados in bags of 3 = $5
Let
B = number of bags of avocados that Alonso buys.
The inequality is:
Cost of Eggs + Cost of Avocados in bags of 3 ≤ Total money with Alonso
2.50 + 5B ≤ 21
5B ≤ 21 - 2.50
5B ≤ 18.5
B ≤ 18.5/5
B ≤ 3.7
The number of bags of avocados Alonso bought can be represented by B ≤ 3.7
Answer:
1) The inequality that describes this scenario is 2.50+5B≤21
2) Alonso can afford at most 9 avocados.

The figures are similar. Find the missing length.Round to the nearest thousandth
Answer:
The missing x = 0.675 m
Step-by-step explanation:
In similar triangles, the corresponding sides are proportion (means their ratios are equal)
In the given figure
∵ The two triangles are similar
∴ Their corresponding sides are proportion
∵ The sides of lengths 1.8 m and x are corresponding sides
∵ The sides of lengths 8.0 m and 3.0 are corresponding sides
∴ [tex]\frac{1.8}{x}[/tex] = [tex]\frac{8.0}{3.0}[/tex]
→ By using cross multiplication
∴ x × 8.0 = 1.8 × 3.0
∴ 8x = 5.4
→ Divide both sides by 8
∵ [tex]\frac{8x}{8}[/tex] = [tex]\frac{5.4}{8}[/tex]
∴ x = 0.675
→ No rounding because there is no digit after the thousandth digit
∴ x = 0.675 m
