The answer is 1. an exponential pattern ,friend (:
Answer:
8 and 6
Step-by-step explanation:
Two numbers are such that their difference, their sum, and their product are to
each other as 1:7:24. Their product must equal what number?
:
Two numbers a & b
Let x = the multiplier
:
a - b = 1x
a + b = 7x
a * b = 24x
:
Add the 1st two equations
a - b = x
a + b = 7x
2a = 8x
a = 4x
or
x = .25a
:
a * b = 24x
Replace 24x; a = 4x therefore:
a * b = 6a
b = 6
;
Using the 1st equation
a - b = 1x
Replace b with 6 and x with .25a
a - 6 = .25a
a - .25a = 6
.75a = 6
a =
a = 8
:
Find the multiplier
a - b = x
8 - 6 = 2
:
Check this
a - b = 2 (1*2)
a + b = 14; (7*2)
a * b = 48: (24*2)
:
The numbers are 8 and 6; their products = 48
I must make some assumptions here about what you may have meant by your "<span>linear equation y=3x−5y=3x−5 y equals 3 x , minus 5."
You've written "y=3x-5" three times on the same line of type. Why is that?
Let's change what you've typed to the following:
</span><span>linear equation y=3x−5
separate linear equation y equals 3x minus 5, or y=3x-5
Please go back and ensure that you have copied down this problem precisely as it was originally presented. Be careful not to duplicate info (as you did in typing "y=3x-5," followed by "</span><span>y equals 3 x , minus 5."
</span><span>
y = 3x - 5 is, as you say, "a linear equation." The slope of this line is 3 and the y-intercept is (0, -5).
As to form: This is a "slope-intercept equation of a straight line."
Other forms include "General form of the equation of a straight line," "Point-slope form."</span>
Start by finding the slope of the line by doing m(slope)=y2-y1 over x2-x1 using the pairs and then plug in the y and x of one of the points into the equation y=mx+b (y in the y and x in the x spot) and solve for b. Then plug the slope (can be a fraction shouldn’t be decimal) and y-intercept (b) back in the equation of a line above and you have your answer!
