Which Option Correctly Shows How This Formula Can Be Rearranged To Isolate X^2?Options In Picture.

Answers

Answer 1

Answer:

A

Step-by-step explanation:

We have:

[tex]\displaystyle m=\frac{x_1-x_2}{y_1-y_2}[/tex]

And we want to isolate x₂.

So, let’s first remove the denominator by multiplying both sides by it:

[tex]\displaystyle m(y_1-y_2)=\frac{x_1-x_2}{y_1-y_2}(y_1-y_2)[/tex]

The right side will cancel. This will leave:

[tex]\displaystyle m(y_1-y_2)=x_1-x_2[/tex]

Now, we can subtract x₁ from both sides. So:

[tex]\displaystyle m(y_1-y_2)-x_1=-x_2[/tex]

Finally, we will multiply both sides by -1. So:

[tex]\displaystyle x_2=-m(y_1-y_2)+x_1[/tex]

Hence, our answer is A.

The ratio of girls to boys at soccer practice is 3:4. If on Saturday there will be a total of 42 players, how many boys will be playing and how many girls?

Answers

Answer:

[tex]Boys = 24[/tex]

[tex]Girls = 18[/tex]

Step-by-step explanation:

Given

[tex]G:B= 3:4[/tex]

[tex]Total = 42[/tex]

Required

Determine the number of boys and girls

We have to convert the ratio to fraction;

Number of girls can be calculated as:

[tex]Girls = \frac{G}{G + B} * Total[/tex]

[tex]Girls = \frac{3}{3 + 4} * 42[/tex]

[tex]Girls = \frac{3}{7} * 42[/tex]

[tex]Girls = 3 * 6[/tex]

[tex]Girls = 18[/tex]

[tex]Boys = Total - Girls[/tex]

[tex]Boys = 42 - 18[/tex]

[tex]Boys = 24[/tex]

Solve the following compound inequality.

A. -2 ≤ x ≤ 5

B. x ≤ -2 OR x ≥ 5

C. x ≤ -15 OR x ≥ 12

D. x ≥ 5

Thank you!

Answers

Answer:

B

Step-by-step explanation:

We have the compound inequality:

[tex]5x+7\leq-3 \text{ or } 3x-4\geq 11[/tex]

Since this is an “OR” inequality, we can solve each inequality individually. So:

1)

We have:

[tex]5x+7\leq-3[/tex]

Subtract 7 from both sides:

[tex]5x\leq -10[/tex]

Divide both sides by 5:

[tex]x\leq-2[/tex]

So, the first solution is above.

2)

We have:

[tex]3x-4\geq 11[/tex]

Add 4 to both sides:

[tex]3x\geq15[/tex]

Divide both side by 3:

[tex]x\geq5[/tex]

Our second solution is above.

Therefore, our solution is:

[tex]x\leq -2 \text{ or } x\geq5[/tex]

Since our original inequality is “OR,” our solution set remains an “OR.”

Hence, our answer is B.

Which of the following inequalities is equivalent
to -31 + 12s <3s + 15 ?

Answers

Answer:

 -31+12s

Step-by-step explanation:

The required inequality that is equivalent to -31 + 12s < 3s + 15 is 9s < 46.

Given that,
To determine the inequalities is equivalent to -31 + 12s <3s + 15.

What is inequality?

Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

Here,

-31 + 12s < 3s + 15
12s - 3s < 15 + 31
9s < 46

Thus, the required inequality that is equivalent to -31 + 12s < 3s + 15 is 9s < 46.

The constant of proportionality for the ratio of cubs to female bears is 3.

The constant of proportionality is typically used when we are comparing something with another thing.

In this case, since every female bear has 3 baby cubs, the constant of proportionality for the ratio of cubs to female bears will be:

= 3/1

Together teammates Pedro and Ricky got 2689 base hits last season Pedro had 281 more hits than Ricky how many hits does each player have?

Answers

Answer: Ricky has 1204 hits and Pedro has 1485 hits

Explanation:

- Let R be the number of hits that Ricky had
- Let P be the number of hits that Pedro had

R + P = 2689

But Pedro has 281 more hit than Ricky

Thus, P = R + 281

Substitute this value in our first equation

R + R + 281 = 2689
2R + 281 = 2689
2R = 2689 - 281
2R = 2408
R = 2408/2
R = 1204

And P = R + 281

But R = 1204

=> P = 1204 + 281 = 1485

Therefore, Pedro has 1485 base hit and Ricky has 1204 hit.

Ryan conducted a 6 day study observing the effects of an organic plant food on the growth of his sprouting bean plant. He tracked these two pieces of info:

1. The amount of plant food remaining in the container after each days study.

2. The height of the plant over time.

Answers

Answer:

Domain: [tex]0\leq x\leq 6[/tex]

Range: [tex]\{0, 12, 24, 36, 48, 60, 72\}[/tex]

Step-by-step explanation:

Let [tex]y[/tex] or [tex]f(x)[/tex] be equal to the amount of plant food that remains after each day.

[tex]x[/tex] be the number of days that have passed.

Total amount of plant food used is 72 mm.

Number of days the experiment goes on is 6 days.

Plant food used each day is [tex]\dfrac{72}{6}=12\ \text{mm}[/tex].

So, the function will be

[tex]y=f(x)=72-12x[/tex]

at

[tex]x=0,y=72[/tex]

[tex]x=1,y=72-12\times 1=60[/tex]

[tex]x=2,y=72-12\times 2=48[/tex]

[tex]x=3,72-12\times 3=36[/tex]

[tex]x=4,72-12\times 4=24[/tex]

[tex]x=5,72-12\times 5=12[/tex]

[tex]x=6,72-12\times 6=0[/tex]

Value of [tex]x[/tex] is the domain which is [tex]0\leq x\leq 6[/tex].

Value of [tex]y=f(x)[/tex] is the range which is [tex]\{0, 12, 24, 36, 48, 60, 72\}[/tex].
