Answer: 6 would be left

Step-by-step explanation: divide 3494 by 8

There will be 6 comics left over after putting them in groups of 8

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given, Bertie has 3494 comic books he wants them in groups of 8.

∴ The no. of groups can be obtained if we divide the total number of books by no. of books in each group which is,

= (3494/8).

= 438×8 + 6.

The image of (10,10) after a dilation by a scale factor of 1/2 centered at the origin is (5, 5)

The point is given as

Point = (10, 10)

The scale factor is given as

k = 1/2 centered at the origin

The image after a dilation by the scale factor is calculated as

Image = Point * k

This gives

Image = (10, 10) * 1/2

Evaluate

Image = (5, 5)

Hence, the image of (10,10) after a dilation by a scale factor of 1/2 centered at the origin is (5, 5)

The number of years for which the money was invested is 5.0 years

From the question, we are to determine how long (in years) the money was invested

From the given information,

Lina invested $7,800 at a simple interest rate of 4.35%

and

She earned $1,696.50 in interest

From the formula for simple interest

I = PRT

Where I is the simple interest

P is the principal

R is the rate

and T is the time in years

From the given information,

I = $1,696.50

P = $7,800

R = 4.35% = 0.0435

Thus,

1696.50 = 7800 × 0.0435 × T

1696.50 = 339.3 × T

T = 1696.50/339.3

T = 5.0 years

Hence, the money was invested for 5.0 years

The correct option is (d).

d) (2,-6) & (4,-16)

Now, To find the correct option that is equivalent to this equation, we can begin by narrowing down the given options.

Since, The slope contains a negative number, that's mean the second point must have a lower y value than the first x value.

Hence, By using this criteria, we can eliminate the first and the third option.

Now, we can check the second and fourth option as;

We can test using by putting in values.

Let's plug in the point values to check whether they work:

Hence, For option 2:

y = -5x + 4

-24 = -5(4) + 4

-24 = -20 + 4

-24 ≠ -16

And, For option 4:

y = -5x + 4

-16 = -5(4) + 4

-16 = -20 + 4

-16 = -16

The value of -4(7/10) - 9(7/15) is -85 / 6.

A fraction represented with its quotient and remainder is a mixed fraction.

For example:

3 4/5 is a mixed fraction, where 3 is the quotient, and 4 is the remainder.

We have,

-4(7/10) - 9(7/15)

Convert each term into a proper fraction.

4 7/10 = (40+7) / 10 = 47 / 10

9 7/15 = (135 + 7) / 15 = 142 / 15

Now,

= -47 / 10 - 142 / 15

The LCM of 10 and 15 is 30

log 2x + log x = 11 => x = 223600, by properties of logarithm.

Now,

log (2x) + log (x) = 11

=> log [(2x)(x)] = 11 (as log (a) + log (b) = log (ab))

=> log (2x²) = 11

Since, generally the base of log is 10, raising them to 10

=> [tex]10^{log_{10}(2x^{2})} = 10^{11}[/tex]

=> 2x² = 10¹¹

=> x² = [tex]\frac{10^{11}}{2}[/tex]

=> x = [tex]10^{5}\sqrt{\frac{10}{2}} = 10^{5}\sqrt5[/tex]

=> x = 10⁵ (2.2360)

=> x = 223600

Hence, log 2x + log x = 11 => x = 223600, by properties of logarithm.

g(-3) = |-3 - 3|

g(-3) = |-6|

g(-3) = 6

Now we can replace g(-3) with 6 in the function composition to get f(g(-3)) = f(6). Find f(6) by plugging x = 6 into the function f(x):

f(x) = x + 3

f(6) = 6 + 3
