2x + 3y = 13<br> y = 3x + 8
kumpel [21]

Step-by-step explanation:

2x+3(3x+8)=13 y=3x+8

2x+9x+24=13 y=3(-1)+8

11x+24=13 y= -3+8 =8-3

11x=13-24 y=5

11x/11= -11/11

x= -1

Write the equation of a line perpendicular to y=3x+1and goes through the point ( 6,2) y=−13x+4 y=−13x−4 y=3x+4 y=3x−4
Korolek [52]

Answer:

y=-\frac{1}{3}x+4

Step-by-step explanation:

step 1

Find the slope of the perpendicular line

we know that

If two lines are perpendicular, then their slopes are opposite reciprocal

(the product of their slopes is equal to -1)

In this problem

we have

y=3x+1

The equation of the given line is m=3

so

the slope of the perpendicular line to the given line is

m=-\frac{1}{3}

step 2

Find the equation of the line in point slope form

y-y1=m(x-x1)

we have

m=-\frac{1}{3}

(x1,y1)=(6,2)

substitute

y-2=-\frac{1}{3}(x-6)

Convert to slope intercept form

y=mx+b

Distribute right side

y-2=-\frac{1}{3}x+2

y=-\frac{1}{3}x+2+2

y=-\frac{1}{3}x+4

Using the numbers 5, 8, and 24, create a problem using no more than four operations (addition, subtraction, multiplication, divi
Oxana [17]

Answer:

There could be many answers to this problem, one being the √(24 x 5 - 8)

Step-by-step explanation:

Irrational numbers are classified as real numbers that are non-terminating and non-repeating decimals.  This means that the number will be a decimal that never ends and does not contain a pattern of any kind.  For example, a decimal that never ends is usually written as: 5.6789234...  This type of number is irrational because the decimal keeps going and shows no pattern of repetition. In the answer given, the value of (24 x 5 -8) is 112.  The square root of 112 is not a perfect square and thus you will get a non-terminating and non-repeated decimal as the final answer, thus making it irrational.
