What's 3x+5y=-7 (show step by step on paper)

Mathematics
1 answer:
Allushta [10]2 years ago
6 0

Answer:

m=-3/5

Step-by-step explanation:

Simplifying

3x + 5y = 7

Solving

3x + 5y = 7

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-5y' to each side of the equation.

3x + 5y + -5y = 7 + -5y

Combine like terms: 5y + -5y = 0

3x + 0 = 7 + -5y

3x = 7 + -5y

Divide each side by '3'.

x = 2.333333333 + -1.666666667y

Simplifying

x = 2.333333333 + -1.666666667y

Which exponential function grows at a faster rate than the quadratic function for zero is less than X is less than three
Ann [662]

Answer:

43.35 years

why?

From the above question, we are to find Time t for compound interest

The formula is given as :

t = ln(A/P) / n[ln(1 + r/n)]

A = $2500

P = Principal = $200

R = 6%

n = Compounding frequency = 1

First, convert R as a percent to r as a decimal

r = R/100

r = 6/100

r = 0.06 per year,

Then, solve the equation for t

t = ln(A/P) / n[ln(1 + r/n)]

t = ln(2,500.00/200.00) / ( 1 × [ln(1 + 0.06/1)] )

t = ln(2,500.00/200.00) / ( 1 × [ln(1 + 0.06)] )

t = 43.346 years

In the graph shown, suppose that f(x) = 3.5x and h(x) = 1.5x. Choose the statement that COULD be true.
faust18 [17]

Answer: D

Step-by-step explanation:

The given functions are

Now these are exponential curves and the bases for the functions are 3.5 & 1.5

Also the graph of g(x) is between f(x) & h(x)

Hence the value of base called the scale factor must be between 3.5 & 1.5.

4 & 5 are more than 3.5

0.9 is smaller than 1.5

But π = 3.14 lies between 3.5 & 1.5.

Hence the only option which can represent the graph of g(x) is

Option D) is the right answer

10) 9 people can paint a bridge in 5 hours,
ale4655 [162]

Step-by-step explanation:

The number of people to paint the bridge is inversely proportional to the number of hours it takes.

(If there are more people, it will take less time etc.)

9 people can paint the bridge in 5 hours.

=> 2 people can paint the bridge in 5 * (9/2) = 22.5 hours.
