Amira is told there is a trick to finding the slope within an equation in standard form, Ax+By=C. She is told she can rewrite this equation in slope-intercept form, y=mx+b, to find the pattern. She correctly rewrites the equation 7x+9y=14 in slope-intercept form as y=− 7/9x +14/9. Which answer explains the pattern for how to find the slope using an equation in standard form?A. In slope-intercept form, the slope is 14/9. These values are C and A, but with the opposite sign, so the slope of the line from the equation in standard form is − C/A.

B. In slope-intercept form, the slope is − 7/9. These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is − A/B.

C. In slope-intercept form, the slope is 14/9. These values are C and B, but with the opposite sign, so the slope of the line from the equation in standard form is − C/B.

D. In slope-intercept form, the slope is − 7/9. These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is − B/A.

Answer 1

Answer:

Answer:

B. In slope-intercept form, the slope is − 7/9. These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is − A/B.

Step-by-step explanation:

Let's convert the standard equation into slope-intercept form:

Ax + By = C ⇒ subtract Ax from both sides
By = -Ax + C ⇒ divide both sides by B
y = -A/Bx + C/B ⇒ converted to slope- intercept form

As we see the slope is -A/B

The equation 7x + 9y = 14 is converted as:

y = -7/9x + 14/9, where the slope is -7/9

Looking at the answer options and the correct one is option B, where both identification of slopes match.

B. In slope-intercept form, the slope is − 7/9. These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is − A/B.

If a sequence is defined recursively by f(0)=2 and f(n+1)=-2f(n)+3 for n is greater than or equal to 0, then f(2) is equal to...?

Answers

We start with f(0) = 2, we can use this value to find out the next value f(1) in our relation.

f(1) = -2 f(0)+3 = -2(2) + 3 =- 4 +3 =-1 Now we know f(1) we can work out f(2):

f(2) = -2 f(1)+3 = -2( -1)+3 = 2 +3 = 5.

So f(2) = 5

Final answer:

To solve the equation 3x + 1 algebraically, subtract 1 from both sides and then divide both sides by 3. The solution is x = -1/3.

Explanation:

To solve the equation 3x + 1 algebraically, you need to isolate the variable x. Let's go step-by-step:

Subtract 1 from both sides of the equation: 3x + 1 - 1 = 0 - 1. This simplifies to 3x = -1.
Divide both sides of the equation by 3 to solve for x: $\frac{3x}{3} = \frac{-1}{3}$. This simplifies to x = -\frac{1}{3}.

So, the solution to the equation 3x + 1 = 0 is x = -\frac{1}{3}. This means that when you substitute x = -\frac{1}{3} into the equation, both sides will be equal.

During harvesting season at Florida Blue Farms, hand pickerscollect about 200 pounds of blueberries per day with a 95%
pack-out rate. The blueberry harvester machine collects about
22,000 pounds of blueberries per day with a 90% pack-out rate.
The pack-out rate is the percentage of collected blueberries
that can be packaged to be sold, based on Florida Blue Farms'
quality standards.
Let h represent the number of days the hand pickers work and
m represent the number of days the harvester machine is used.
Which of the following algebraic expressions can be used to
estimate the amount of collected blueberries that are packed at
the Florida Blue Farms for fresh consumption this season?

A (0.95h+200)(0.90+22000)

B 0.95(200h)+0.90(22000m)

C 200.95h+22000.90m

D (200h+0.95)(22000m+0.90)

Answers

The farm uses two harvesting tools for packages that needs to be sold. So, we have to consider the rates of both harvest tools and the number of harvest by both tools. The algebraic expression is: $0.95(200h) + 0.90(22000m)$

Given that

$h \to$ days of hand pickers word

$m \to$ days harvester machine is used

$n_h = 200$ --- pounds of hand pickers

$n_m = 22000$ -- pounds of harvester

$r_h = 95\%$ -- pack out rate of hand pickers

$r_m = 90\%$ -- pack out rate of harvester

The expression to estimate the amount is calculated as:

$Amount = r_h * n_h + r_m * n_m$ --- i.e. pounds of hand picker * its pack out rate + pounds of harvester * its pack out rate

So, we have:

$Amount = 95\% * 200h + 90\% * 22000m$

Express as decimal

$Amount = 0.95 * 200h + 0.90 * 22000m$

Rewrite as:

$Amount = 0.95(200h) + 0.90(22000m)$

Hence, option (b) is correct.

In basketball, Shaquille makes 40% of his free throw attempts. He goes to the free throw line to shoot one-and-one (if he makes the first shot, he gets to shoot one more). He scores 1 point per free throw. What is the expected value of the number of points he will score?

Answers

This question is a little bit tricky. Anyway, the best answer to the question would be 2 points. The expected value of the number of points he will score would be two points in every successful free throw attempt he makes. It just has a probability of .40 - which means that ,say, in 10 free throw shots, there's a tendency he will only make 4 of them.

Answer:

4 he makes 4 shots.

Step-by-step explanation:

if there are 40% and his shots equal 1 the answer is 4.
