Two numbers have a difference of 4 and a sum of -8. What is their product?

1 answer:

7 0

Assume the two numbers are x and y
the difference = 4 , so x - y = 4
the sum = -8 , so x + y = -8
by solving both equations
2x = -4
x = -2
-2 + y = -8
y = -6
the two numbers are -2 and -6

2. Find the equation of a line<br>a) With a slope of 4, passing through the origiin

madreJ [45]

Answer:

$y=4x$

Step-by-step explanation:

<u>Equation of the line</u>

A line can be expressed in many forms.

The equation of the line in slope-intercept form is:

y=mx+b

Being m the slope and b the y-intercept.

The point-slope form of the equation of a line is:

y-k=m(x-h)

Where m is the slope and (h,k) is a point through which the line passes.

The equation of a line passing through points (x1,y1) and (x2,y2) can be found as follows:

$\displaystyle y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)$

We are required to find a line with slope m=4 passing through the origin (0,0).

Using the point-slope form:

y-0=4(x-0)

Simplifying

$\boxed{y=4x}$

How would i solve this problem using log base 10

Archy [21]

First isolate the power of 10 on the right side by dividing both sides by 5:

$100=5\cdot10^{0.3t}\implies20=10^{0.3t}$

Now you're free to take the logarithm and simplify where you can:

$\log_{10}20=\log_{10}10^{0.3t}=0.3t\log_{10}10=0.3t$

Then solve for $t$ :

$t=\dfrac{\log_{10}20}{0.3}\approx4.34$
