Find the values for a, b, and c for this quadratic equation. 3x^2 - x - 1 = 0
Answer:
a = 3, b = -1, c = -1
Step-by-step explanation:
3x² - x - 1 = 0 ⇒ 3x² - 1x - 1 = 0
a = 3, b = -1, c = -1
2x+3-3=-6
x=3 ? Solve
[tex]2(x)+3-3=-6\\2(3)+3-3=-6\\6+3-3=-6\\6=-6\\[/tex]
[tex]x\neq 3[/tex]
As we can see, x cannot be equal to 3 as 6 cannot equal -6.

Give the slope of each of the following lines Name a point on each line
y+2=2/3 (x-4)
Answer:
See answer below
Step-by-step explanation:
y + 2 = 2/3(x - 4)
y + 2 = 2/3x - 8/3
y = 2/3x - 8/3 - 2
y = 2/3x - 2 2/3 - 2
y = 2/3x - 4 2/3 or y = 2/3x - 14/3
Slope = 2/3
The value of the slope of the line is 2/3.
Used the concept of the equation that states,
The equation of a line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Given that;
The equation of the line,
y + 2 = 2/3 (x - 4)
Now comparing the given equation of the line with the equation of a line in point-slope form,
y + 2 = 2/3 (x - 4)
y - (- 2) = 2/3 (x - 4)
Therefore, the slope of the line is 2/3

1. A nutrition company is marketing a low-caloric snack brownie. A serving size of the snack is 3 brownies
and has a total of 50 calories.
(c) Determine how many calories 14 brownies
would have. Round to the nearest calorie.
(d) If c represents the number of calories and b
represents the number of brownies, write a
proportional relationship involving c and b and
solve it for c.
Proportional relationships are used to represent direct variation
The number of calories in 14 brownies is 233, and the proportional relationship is [tex]\mathbf{c = \frac{50b}{3}}[/tex]
Let b represents brownies and c represents calories.
So, the relationship is given as:
b : c = 3 : 50
Express as fractions
[tex]\mathbf{\frac bc = \frac{3}{50}}[/tex]
Multiply both sides by c
[tex]\mathbf{b = \frac{3}{50}c}[/tex]
When the number of brownies is 14, we have:
[tex]\mathbf{14 = \frac{3}{50}c}[/tex]
Multiply both sides by 50/3
[tex]\mathbf{14 \times \frac{50}{3} = c}[/tex]
[tex]\mathbf{233 = c}[/tex]
Rewrite as:
[tex]\mathbf{c = 233 }[/tex]
Make c the subject in [tex]\mathbf{b = \frac{3}{50}c}[/tex]
[tex]\mathbf{c = \frac{50b}{3}}[/tex]
Hence, the number of calories in 14 brownies is 233, and the proportional relationship is [tex]\mathbf{c = \frac{50b}{3}}[/tex]

Step-by-step explanation:
In the given figure we have two corresponding angles.
We know that corresponding angles are equal to each other
So,
2x+5 = 1352x = 135 - 52x = 130x = 130/2x = 65Therefore, x = 65°
Corresponding angles are same
[tex]\\ \sf\longmapsto 2x+5=135[/tex]
[tex]\\ \sf\longmapsto 2x=135-5[/tex]
[tex]\\ \sf\longmapsto 2x=130[/tex]
[tex]\\ \sf\longmapsto x=130/2[/tex]
[tex]\\ \sf\longmapsto x=65°[/tex]

A store is having a sale where movies are 15% off their original price a movie is on sale for 22.10$ what was the original price of the movie
Answer:
The answer is $26
Step-by-step explanation:
So, the price after the sale was $22.10 and to find the original price you have to divide the price by 1- the discount. So, I did $22.10/ 1-0.15. Then, I got $22.10/0.85 and then I divided them by each other and got $26.

what is 11.10 as a fraction?
Answer:
11 1/10
Step-by-step explanation:
11 is a whole nuber so then 1 over 10
Answer:
It is 11 1/10!
Step-by-step explanation:
I know this because the first thing to do here is to show you that any number can be a fraction if you use a 1 as the denominator. What we really want to do though, is get rid of the decimal places completely so that the numerator in our fraction is a whole number. To do this, we have to count the numbers after the decimal point, which in this case is 10. To get a whole fraction we need to multiply both the numerator and the denominator by 10 if there is one number after the decimal point, 100 if there are two numbers, 1,000 if it's three numbers and 10,000 if it's...well, you get the idea! In our case 10 is 2 digits long so we need to multiply the numerator and denominator by 100. Now we just need to do that multiplication to get our whole fraction! The next step is to simplify this fraction and, to do that, we need to find the greatest common factor (GCF). This is sometimes also known as:
Greatest Common Divisor (GCD)Highest Common Factor (HCF)Greatest Common Denominator (GCD)In the case of 1110/10 and 100/10, the greatest common divisor is 10. This means that to simplify the fraction we can divide by the numerator and the denominator by 10 and we get 111/10. And there you have it! In just a few short steps we have figured out what 11.10 is as a fraction. 11 1/10!

What is an inverse proportion?
When there is an inverse proportion, as one of the variable increases, the other variable decreases. As the number of people who share the money increases, the amount of money each person would get would become smaller.
The formula used to represent inverse proportion is:
y = k/x
• y = dependent variable
• x = independent variable
• k = constant of proportionality
