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
Answer:
Hey there! The answer to your question is 30%
Step-by-step explanation:
Work:
50%+20%=70
Than you do 100-70 and the answer would be 30%

Answer:
3+1=4
3 + 2 sqrt2
Step-by-step explanation:
0.009 because whenever you multiply a decimal by 10, 100, 1000, 10000 etc. you move the decimal to the right however may zeros are in the number. EXAMPLE:
0.00023*1000=0.23. Hope this helped! Also, dividing is the same, you just move it to the left.
ANSWER
EXPLANATION
The perimeter of the triangle is the distance around the triangle.
We need to apply our ability to convert word problems in to mathematical expressions.
we were told that the bottom of the triangle is units.
From the diagram perimeter
Four times the length of the bottom will be .
12 more than 4 times the bottom will be
Hence another side of the triangle is
Finally we were told that the last side is 3 more than the bottom, that will be
