Answer:

Step-by-step explanation:

a² + c(2+b) = a² + 2c+bc

Expand first.

a² + 2c+bc = 3² + 2(5) + 6×5

Substitute a, b and c with actual values.

3² + 2(5) + 6×5 = 9 + 10 + 30

Evaluate.

9 + 10 + 30 = 49

Simplify.

Answer:

46 is the answer

Step-by-step explanation:

Because:

a2 + c(2+b)

3(2) + 5(2+6)

6 + 5(8)

6 + 40

Use elimination to solve the system of equations:

tatyana61 [14]

2x+3y=1;x+4y=−2

Steps:

Multiply the second equation by -2, then add the equations together.

(2x+3y=1)

−2(x+4y=−2)

Becomes:

2x+3y=1

−2x−8y=4

Add these equations to eliminate x:

−5y=5

Then solve−5y=5for y:

−5y−5=5−5(Divide both sides by -5)

y=−1

Now that we've found y let's plug it back in to solve for x.

Write down an original equation:

2x+3y=1

Substitute−1foryin2x+3y=1:

2x+(3)(−1)=1

2x−3=1(Simplify both sides of the equation)

2x−3+3=1+3(Add 3 to both sides)

2x=4

2x2=42(Divide both sides by 2)

x=2

x=2 and y=−1

Suppose that a regression line for some data transformed with logarithms predicts that when x equals 4, log(y) will equal 3.331.

deff fn [24]

Option D

The regression line predicts that at x = 4, y equals 2143

Solution:

Given that when x equals 4, log(y) will equal 3.331

To find: Find y when x equals 4

Since we have given that,

When x = 4,

$\text{ log } y = 3.331$
