Which is the solution set of the inequality 15 y minus 9 less-than 36 y greater-than nine-fifths y less-than nine-fifths y less-

Vaselesa [24]

Answer:

C. y<3

Step-by-step explanation:

We are required to determine the solution set of the inequality

$15y-9$

Step 1: Add 9 to both sides

$15y-9+9$

Step 2: Divide both sides by 15

$15y \div 15$

The solution set of the given inequality is: y<3.

The correct option is C.

Which sequence of transformations proves that shape I is similar to shape II?

4vir4ik [10]

Note that if you simply reflected it and dilated it, it would be too far to the left

note that the distances bewteen the axises in image 1 were 1 and 3in image 3,the distances are 2 and 6
seems to be 3 times
so it's the 90 counterclockwise rotation and dilation by scale factor of 3
answer is last one

Write an equation of the line that passes through the points (-3,-9) and (5,-9)

skelet666 [1.2K]

Answer:

slope of a line m : 0

Equation of line : y=- 9

Step-by-step explanation:

P1 : (X1 , Y1 ) (-3 , -9)

P2 : (X2 , Y2) (5 , -9)

Slope of line (m) is caculated as ,

m = ( y2-y1)/(x2 - x1)

m = (-9 - (-9))/(5 - (-3))

m = 0

equation of line : y = mx+b

using P1 (-3 , -9)

= > (-9) = (0)(-3) + b

= > -9 = b

hence b = -9

equation of Line is

y = -9

Dana Thacker's bank granted her single payment loan of 10,450 she agreed to repay the loan in 75 days at an exact interest rate

il63 [147K]

Using simple interest, it is found that the maturity value of the loan is of 10,638.

<h3>Simple Interest</h3>

The amount of money after <em>t years </em>in simple interest is modeled by:

$A(t) = A(0)(1 + rt)$

In which:

A(0) is the initial amount.

r is the interest rate, as a decimal.

In this problem:

A loan of 10450 is taken, hence $A(0) = 10450$ .

Interest rate of 8.25%, hence $r = 0.0825$

The loan will be repaid in 75 days, considering the time in years, $t = \frac{75}{365}$

Then, the maturity value of the loan is:

$A(t) = A(0)(1 + rt)$

$A\left(\frac{75}{365}\right) = 10450\left[1 + 0.0875\frac{75}{365}\right] = 10638$

The maturity value of the loan is of 10,638.
