ANY JESUS HELPERS PLEASE HELP The incorrect work of a student to solve an equation 2(y + 4) = 4y is shown below: Step 1: 2(y + 4

) = 4y Step 2: 2y + 6 = 4y Step 3: 2y = 6 Step 4: y = 3 Which of the following explains how to correct Step 2 and shows the correct value of y? The equation should be y + 4 = 4y after division by 2; y = 5 The equation should be y + 4 = 4y after division by 2; y = 2 2 should be distributed as 2y + 8; y = 4 2 should be distributed as 2y + 8; y = 2

Answer:

2 should be distributed as 2y + 8; y = 4

Step-by-step explanation:

Step 2 is wrong.

2(y + 4) = 4y

The step to solve is to expand brackets or distribute 2, not divide both sides by 2.

2y + 8 = 4y

Subtract both sides by 2y.

8 = 2y

Divide both sides by 2.

4 = y

Answer:

2 should be distributed as 2y + 8; y = 4

Step-by-step explanation:

2(y + 4) = 4y

Distribute

2y + 8 = 4y

Step 2 is incorrect because the added instead of multiplied

Continuing on to correct the problem

Subtract 2y from each side

2y+8-2y = 4y-2y

8 = 2y

Divide by 2

8/2 = 2y/2

4 =y

Suppose an opaque jar contains 3 red marbles and 10 green marbles. The following exercise refers to the experiment of picking tw
kow [346]

Answer:

\frac{5}{13}

Step-by-step explanation:

Given,

Red marbles = 3,

Green marbles = 10,

So, the total marbles = 3 + 10 = 13,

\because \text{Probability}=\frac{\text{Favourable outcomes}}{\text{Total outcomes}}

Since, here replacement is not allowed,

Thus, the probability of getting a green marble and a red marble

= first red and second green + first green second red

=\frac{3}{13}\times \frac{10}{12}+\frac{10}{13}\times \frac{3}{12}

=2\times \frac{3}{13}\times \frac{10}{12}

=\frac{30}{78}

=\frac{5}{13}

Note : The probability of getting a green marble first and a red marble second

= \frac{10}{13}\times \frac{3}{12}

=\frac{30}{156}

=\frac{5}{26}

5-year Treasury bonds yield 5%. The inflation premium (IP) is 1.9%, and the maturity risk premium (MRP) on 5-year bonds is 0.4%.
Eddi Din [679]

Answer:

real risk-free rate = 2.7 %

Step-by-step explanation:

Given data

Treasury bonds yield r  = 5%

time = 5 year

(IP) = 1.9%

MRP = 0.4%

to find out

real risk-free rate r*

solution

we will find real risk-free rate r* by the given formula that is

Treasury bonds yield = real risk-free rate + IP + MRP + default risk premium + liquidity premium

so here default risk premium and liquidity premium both are zero

put all the other value we get real risk-free rate

real risk-free rate = 5% - 1.9 % - 0.4%

real risk-free rate = 2.7 %

Any one Know the Answer To This Algebra 1
alexdok [17]

Answer:

The correct answer is B. -3.

Step-by-step explanation:

To solve this problem, we need to plug in -3 for all of the values of x in the equation.  If we do this, we get:

f(x) = 2x + 3

f(-3) = 2(-3) + 3

Now, we can just simplify the expression found on the right side of the equation using PEMDAS.  First, we should perform the multiplication.

f(-3) = -6 + 3

Next, we should add our final two terms together.

f(-3) = -3

Therefore, the correct answer is -3.

Hope this helps!
