Step-by-step explanation:
The first thing we have to do before we can actually do the problem is turn the words into a math equation.
If we use <em>x </em>as our "number," we see that "The sum of a number and 2" can also be written as <em>x</em>+2. The word "Is" almost always means (=), so now we have (<em>x</em>+2) = . The very last part, "6 less than twice that number," means 2<em>x - </em>6.
So, our whole equation is, (<em>x </em>+ 2) = (2<em>x </em>- 6), which simplifies to -<em>x </em>= -8, or
<em>x</em> = 8
The first step to solving an equation like this is to find the slope of a line that will be perpendicular to the line given. The slope of a line that's perpendicular to another line is the negative reciprocal. The negative reciprocal of -1/5 is 5. So, so far our equation is y = 5x + b. Now, to find what b is equal to, we should substitute the values of x and y from the point (1,2) since we know that our line goes through the point. Our equation becomes:
2 = 5 + b
b= -3
That means that the equation of our new line is y = 5x - 3
The answer to your equation is z = 7

Answer:
no
Step-by-step explanation:
you will not incur a delivery charge because you live in the 25 mile radius, because your house is within the radius, so you wouldn't incur the delivery charge. when they say a 25 mile radius, that means in every direction.
