damaskus [11]

Answer:

Step-by-step explanation:

we need the equation to be like y=mx+b so we have to simplify our equation

2y=2x+6

divide everything by 2

so it’s y=x+3 and that’s ur answer

A new graph is formed from y = 5x by changing the slope to 9 and y-intercept to 8. Which statement about the new relationship is
shusha [124]

Answer:

The new graph has a steeper slope and a y-intercept of 8.

Step-by-step explanation:

From Analytical Geometry, we define a straight line by following first order polynomial (linear function):

y = m\cdot x + b (1)

Where:

x - Independent variable.

y - Dependent variable.

b - y-Intercept.

m - Slope.

And the slope represents the change in dependent variable (\Delta y) divided by the change in independent variable (\Delta x). That is:

m = \frac{\Delta y}{\Delta x}

If m_{1} > 0 and m_{2} > m_{1}, then the new line is steeper with respect to the original line.

Let y = 5\cdot x, its slope and y-intercept are 5 and 0, respectively. If slope is changed into 9 and y-intercept becomes 8, then the new graph has a steeper slope and a y-intercept of 8.

What is 3 tenths greater than 80%
elena-14-01-66 [18.8K]

we know that


3 tenths is equal to

\frac{3}{10} =0.30


80% is equal to

\frac{80}{100} =0.80

so


3 tenths greater than80% is equal to add

0.30+0.80=1.10

therefore


the answer is

1.10
