Step-by-step explanation:

y = a {b}^{x}  \\ b =  \frac{0.0006}{0.006}  = 0.1 \\ a = 6 \\ y =6 \times   {0.1}^{x}

The graphs below represent the equations y = 2* and y = 2x + 1.<br> Graph 1<br> Graph 2
sveticcg [70]

Answer:

a. Graph 1 is y=2^x and Graph 2 is y=2x+1

b. The slope increases over time on Graph 1, and remains the same on Graph 2

c. Graph 1 is exponential (y=2^x) and Graph 2 is linear (y=mx+b)

Hope this helps!

Step-by-step explanation:

a:  y=2* is exponential, so it is graph 1 (it makes a curve) y=2x+1 is linear (makes a line), and it has a slope of 2 and a y-intercept of 1, so y=2x+1 is graph 2!

b. slopes of Exponential Functions usually continue to increase (unless the number that is being affected by the exponent x is less than 1, in which they would continue to decrease), and linear functions have a set slope (m in y=mx+b)

c. Explanation is in the answer (it says to explain)

Perpendicular to the line 4x - 6y + 7 = 0 , passing through (3, 4) .
PilotLPTM [1.2K]

Answer:

The equation of line perpendicular to given line passing through (3,4) is:

y = -\frac{3}{2}x+\frac{17}{2}

Step-by-step explanation:

Given equation of line is:

4x - 6y + 7 = 0

Given equation is in standard form. It has to be converted into slope-intercept form to extract slope from the equation.

So,

4x+7 = 6y\\6y=4x+7\\\frac{6y}{6} = \frac{4x+7}{6}\\y = \frac{4}{6}x+\frac{7}{6}\\y=\frac{2}{3}x+\frac{7}{6}

The standard form of slope-intercept form of equation is:

y=mx+b

Here, the co-efficient of x is the slope of the line.

So the slope of given line is: 2/3

m = 2/3

The product of slopes of two perpendicular lines is -1

Let m1 be the slope of line perpendicular to given line

Then

m.m_1 = -1\\\frac{2}{3} . m_1 = -1\\m_1 = -1*\frac{3}{2}\\m_1 = -\frac{3}{2}

The equation of perpendicular will be:

y = m_1x+b

Putting the value of slope

y = -\frac{3}{2}x+b

To find the value of b, putting (3,4) in the equation

4 = -\frac{3}{2}(3)+b\\4 = -\frac{9}{2}+b\\b = 4+\frac{9}{2}\\b= \frac{8+9}{2}\\b=\frac{17}{2}

So the equation of line perpendicular to given line passing through (3,4) is:

y = -\frac{3}{2}x+\frac{17}{2}
