Answer:

Answer:

$1695.31

Step-by-step explanation:

The appropriate formula is ...

... I = Prt

where P is the principal amount invested, r is the interest rate, and t is the time period. In this problem, the interest rate is an annual rate, so t must be expressed in years. There are 12 months in a year, so 15 months is 15/12 years.

... I = 35000×0.03875×(15/12)

... = 1695.3125 ≈ 1695.31

9x - y = 15 2x + 8y = 28

9x - y = 15

2x + 8y = 28

Use the substitution method.

Solve for y in the first equation.

9x - y = 15

-y = 15 - 9x

y = -15 + 9x

Now plug in y into the second equation.

2x + 8(-15 + 9x) = 28

2x - 120 + 72x = 28

74x - 120 = 28

74x = 148

x = 2

Plug x back into the rewritten first equation.

y = -15 + 9(2)

y = -15 + 18

y = 3

x = 2, y = 3

2x + 8y = 28

Use the substitution method.

Solve for y in the first equation.

9x - y = 15

-y = 15 - 9x

y = -15 + 9x

Now plug in y into the second equation.

2x + 8(-15 + 9x) = 28

2x - 120 + 72x = 28

74x - 120 = 28

74x = 148

x = 2

Plug x back into the rewritten first equation.

y = -15 + 9(2)

y = -15 + 18

y = 3

x = 2, y = 3

if a line crosses the y-axis at (0, 1) and has a slope of `4/5`, what is the equation of the line? A. 4y − 5x = 5 B. y − 4x = 5 C. 5y + 4x = 5 D. 5y − 4x = 5

Answer:

option (d) is correct.

if a line crosses the y-axis at (0, 1) and has a slope of , then equation of line is 5y - 4x = 5.

Step-by-step explanation:

Given : if a line crosses the y-axis at (0, 1) and has a slope of .

We need to find the equation of line.

Equation of line is of the form y = mx + c, where m is the slope of line and c is the y- intercept. that is the point where line meets y- axis.

Given y intercept at (0, 1 ) ⇒ c = 1

Also, slope m =

Substitute it in equation, we get ,

y = mx + c ⇒

Solving , we get equation of line as ,

5y = 4x + 5 ⇒ 5y - 4x = 5

Thus, option (d) is correct.

if a line crosses the y-axis at (0, 1) and has a slope of , then equation of line is 5y - 4x = 5.

Answer:

Choice D is correct answer.

Step-by-step explanation:

From question statement, we observe that

Slope is given and a point is given .

slope = 4/5 and point is (0,1)

y = mx+c is equation of line where m is slope and c is y-intercept.

y-intercept is a point where the value of x is zero.

hence, y-intercept = c = 1

Putting the given values in formula, we have

y = (4/5)x+1

y =( 4x+5) / 5

5y = 4x+5

Adding -4x to both sides of above equations, we have

5y-4x = 4x+5-4x

5y-4x = 5 is equation of line that crosses the y-axis at (0,1) and has a slope of 4/5.

Jessie arranged some bouquets of roses for a charity sale. A big bouquet had 36 stalks of roses and a small bouquet had 12 stalks of roses. She arranged 4 times as many small bouquets of roses as big bouquet of roses. If Jessie arranged 1260 stalks of roses altogether: a. How many big bouquets of roses did she arrange

b.How many small bouquets of roses did she arrange

Answer:

a) 15 big bouquets

b) 60 small bouquets

Step-by-step explanation:

We are given the following information:

Number if roses in big bouquet = 36

Number of roses in small bouquet = 12

Let y be the number of big bouquet and x be the number of small bouquets.

We are given that small bouquets are four times the big bouquets.

Also, total number of roses used for arrangement = 1260

Putting x = 4y in the above equation, we get,

Thus, Jessie arranged 60 small bouquets and 15 big bouquets.

Big - 1260/36 35 bouquets

Small - 1260/12 105 bouquets

Small - 1260/12 105 bouquets
