Answer:

Let's solve for f.

Step 1: Multiply both sides by fr.

4f+8r=

5fr

Step 2: Multiply both sides by g.

4fg+8gr=5fr

Step 3: Add -5fr to both sides.

4fg+8gr+−5fr=5fr+−5fr

4fg−5fr+8gr=0

Step 4: Add -8gr to both sides.

4fg−5fr+8gr+−8gr=0+−8gr

4fg−5fr=−8gr

Step 5: Factor out variable f.

f(4g−5r)=−8gr

Step 6: Divide both sides by 4g-5r.

f(4g−5r)

4g−5r

−8gr

4g−5r

−8gr

4g−5r

Answer:

What value of b will cause the system to have an infinite number of solutions? A system of equations. y equals 6 x plus b. negat

Natasha_Volkova [10]

The value of b is 6 for which the system of equation will have an infinite number of solutions option third is correct.

<h3>What is a linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have two linear equations:

y = 6x - b ..(1)

$\rm -3x + \dfrac{1}{2}y = -3$ ..(2)

From the second equation:

$\rm -3x + \dfrac{1}{2}y = -3$

-6x + y = -6

After rearranging:

y = 6x - 6 ..(3)

On comparing equation (1) and (3)

b = 6

Thus, the value of b is 6 for which the system of equation will have an infinite number of solutions option third is correct.

Can someone explain how to answer this

olya-2409 [2.1K]

Answer:

q= -ck+dp/

-k+d

Step-by-step explanation:

Step 1:

Multiply both sides by p.

dp=ck−kq+pq

Step 2:

Flip the equation.

ck−kq+pq=dp

Step 3:

Add -ck to both sides.

−kq+pq=−ck+dp

Step 4:

Factor out variable q.

q(−k+p)=−ck+dp

Step 5:

Divide both sides by -k+p.

q= -ck+dp/

-k+d

Sorry if it's all letters and u needed numbers.

How Many Close Confidants Do People Have? In a recent study,1 2006 randomly selected US adults (age 18 or older) were asked to g

yaroslaw [1]

Answer:

0.08065

Step-by-step explanation:

Given that in a recent study,1 2006 randomly selected US adults (age 18 or older) were asked to give the number of people in the last six months with whom you discussed matters that are important to you.

If X is random variable then X has mean 2.2 and s = 1.4

n=2006

Std error of mean = $\frac{1.4}{\sqrt{2006} } \\=0.03126$

For 99% since sample size is large, t and z distn almost coincide.

Hence we can take 2.58 as critical value

Margin of error at 99% = $2.58*0.03126\\=0.08065$
