Use the work shown to find the solutions of the quadratic equation. x2 – x –3/4=0 x2 – x = 3/4
Answer:
x = - [tex]\frac{1}{2}[/tex], x = [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Given
x² - x - [tex]\frac{3}{4}[/tex] = 0
Multiply through by 4 to clear the fraction
4x² - 4x - 3 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 4 × - 3 = - 12 and sum = - 4
The factors are + 2 and - 6
Use these factors to split the x- term
4x² + 2x - 6x - 3 = 0 ( factor the first/second and third/fourth terms )
2x(2x + 1) - 3(2x + 1) = 0 ← factor out (2x + 1) from each term
(2x + 1)(2x - 3) = 0
Equate each factor to zero and solve for x
2x + 1 = 0 ⇒ 2x = - 1 ⇒ x = - [tex]\frac{1}{2}[/tex]
2x - 3 = 0 ⇒ 2x = 3 ⇒ x = [tex]\frac{3}{2}[/tex]
The solutions are x = 3 and x = -7.
To solve the quadratic equation, we first need to bring it to the standard form of ax2 + bx + c = 0. In the example given, we have the equation x2 + 4x - 21 = 0, where a = 1, b = 4, and c = -21. To find the solutions for x, we will use the quadratic formula, which is x = (-b ± √(b2 - 4ac)) / (2a).
Substituting the values of a, b, and c into the quadratic formula, we get:
x = (-(4) ± √((4)2 - 4(1)(-21))) / (2(1))
x = (-4 ± √(16 + 84)) / 2
x = (-4 ± √100) / 2
x = (-4 ± 10) / 2
Which gives us two solutions:
x = (6 / 2) = 3
x = (-14 / 2) = -7
Therefore, the solutions to the quadratic equation x2 + 4x - 21 = 0 are x = 3 and x = -7.

Write the equation of the line that passes through the points (8, –1) and (2, –5) in standard form, given that the point-slope form is y + 1 = (x – 8).
Answer:
[tex]2x-3y=19[/tex]
Step-by-step explanation:
we have the ordered pairs
(8, –1) and (2, –5)
Find the slope
The formula to calculate the slope between two points is equal to
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
substitute the values in the formula
[tex]m=\frac{-5+1}{2-8}[/tex]
[tex]m=\frac{-4}{-6}[/tex]
simplify
[tex]m=\frac{2}{3}[/tex]
The equation of the line in point slope form is
[tex]y-y1=m(x-x1)[/tex]
we have
[tex]m=\frac{2}{3}[/tex]
[tex]point\ (8,-1)[/tex]
substitute
[tex]y+1=\frac{2}{3}(x-8)[/tex]
Convert to standard form
The equation of the line in standard form is equal
[tex]Ax+By=C[/tex]
where
A is a positive integer
B and C are integers
we have
[tex]y+1=\frac{2}{3}(x-8)[/tex]
Multiply by 3 both sides to remove the fraction
[tex]3y+3=2(x-8)[/tex]
apply distributive property right side

A computer can sort x objects in t seconds, as modeled by the function
below:
t=0.007x2 + 0.003x
How many objects are required to keep the computer busy for exactly 9
seconds?
Round to the nearest whole object.
Answer:
36 objects
Step-by-step explanation:
You want the value of x when t=9, so you're solving ...
9 = 0.007x^2 +0.003x
9 = 0.007(x^2 + 3/7x)
From here, we observe that an approximation is probably sufficient.
9/0.007 = x(x +3/7) . . . . . the expression on the right is nearly x^2
x ≈ 3/√.007 ≈ 35.9 ≈ 36
We can check:
.007(36)(36 3/7) = 9.18
.007(35)(35 3/7) = 8.68
To keep the computer busy for 9 seconds, it needs to sort 36 objects.
A line passes through the point (-8,8) and has a slope of -3/2. Write an equation in point-slope form for a this line.
Answer:
y-8=-3/2(x+8)
Step-by-step explanation:
y-y1=m(x-x1)
y-8=-3/2(x-(-8))
y-8=-3/2(x+8)
Final answer:
The equation of the line in the point-slope form that passes through (-8, 8) with a slope of -3/2 is y - 8 = (-3/2)(x + 8).
Explanation:
To write an equation in point-slope form for a line that passes through a given point with a known slope, we use the formula y - y1 = m(x - x1), where (x1, y1) is the point the line passes through and m is the slope of the line.
For the line that passes through the point (-8, 8) with a slope of -3/2, we substitute these values into the point-slope form equation:
y - 8 = (-3/2)(x + 8)
This equation represents the specific line asked in the problem.

You prepare 8 scoops of dog food for 4dogs and prepare 12.5 scoops of dog food for 5 dogs is there a propositional relationship between the number of scoops and the number of dogs?
Answer:
The relationship between the number of scoops and the number of dogs is not proportional
Step-by-step explanation:
Let
x ----> the number of scoops
y ----> the number of dogs
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form [tex]k=\frac{y}{x}[/tex] or [tex]y=kx[/tex]
First situation
You prepare 8 scoops of dog food for 4 dogs
x=8, y=4
Find the constant of proportionality k
[tex]k=\frac{y}{x}[/tex]
substitute the values of x and y
[tex]k=\frac{4}{8}=0.5[/tex]
Second situation
You prepare 12.5 scoops of dog food for 5 dogs
x=12.5, y=5
Find the constant of proportionality k
[tex]k=\frac{y}{x}[/tex]
substitute the values of x and y
[tex]k=\frac{5}{12.5}=0.4[/tex]
Compare the values of k
[tex]0.5\neq 0.4[/tex]
The values of k are not equal
therefore
The relationship between the number of scoops and the number of dogs is not proportional
Which would you rather have: 21% of $3,876 or 17% of $4,552? choose an inequality sign.
Step-by-step explanation:
21 percent of 3,876 is 813.96$, and 17 percent of 4552 is 773.67$. 813.96>773.67
21% of $3,876 is $813.96, while 17% of $4,552 is $773.84. Therefore, 21% of $3,876 inequality sign is greater than 17% of $4,552.
Explanation:Choosing between 21% of $3,876 or 17% of $4,552 involves calculating each percentage of the given amounts to compare which is greater. To do this:
Calculate 21% of $3,876: 0.21 × 3876 = $813.96.
Calculate 17% of $4,552: 0.17 × 4552 = $773.84.
Comparing these two amounts using an inequality sign, we see that $813.96 is greater than $773.84. So, you would rather have 21% of $3,876 than 17% of $4,552.
The inequality would be written as:
21% of $3,876 > 17% of $4,552

express the ratio in its simpilest form
4:2:2
To simplify the ratio 4:2:2, divide each part by the greatest common factor, which is 2, resulting in a simplest form of 2:1:1.
To express the ratio 4:2:2 in its simplest form, you need to divide each term of the ratio by the greatest common factor of all the terms. In this case, the greatest common factor of 4, 2, and 2 is 2. Therefore, when you divide each part of the ratio by 2, the simplest form of the ratio is 2:1:1.
Here's a step-by-step breakdown:
Identify the greatest common factor (GCF) of the numbers in the ratio. GCF of 4, 2, and 2 is 2.
Divide each term of the ratio by the GCF. So, 4 divided by 2 is 2, and 2 divided by 2 is 1.
Write down the simplified ratio: 2:1:1.
This method is similar to the way coefficients in a balanced chemical equation can be simplified, or how ratios can be used in genetics to represent phenotypic distribution in a dihybrid cross. In health sciences, ratios such as 1:1000 are expressed in simplest form. Similarly, in engineering, gear ratios like 2:1 are given in the simplest way to indicate how many turns of an input gear will result in one turn of an output gear.
Captain buys a 100g bar of chocolate. He eats 3/5 of his bar. How many grams of chocolate are left?
Answer:
40g of chocolate are left.
Step-by-step explanation:
3/5*100=300/5=60
100-60=40
Final answer:
To find the amount of chocolate left, subtract the amount eaten from the original 100g bar.
Explanation:
To find the number of grams of chocolate left, you need to subtract the amount Captain ate from the original 100g bar. Captain ate 3/5 of the bar, so you can calculate the amount eaten by multiplying 3/5 by 100g. This gives you 60g. To find the amount left, you subtract 60g from 100g. The answer is 40g.
