Answer:
A 5
Step-by-step explanation:
Parts on the left have the same ratio as parts on the right.
... x/(x+5) = (x -2)/(x +1)
Multiplying by (x+5)(x+1), we get
... x(x +1) = (x -2)(x +5)
... x² +x = x² +3x -10 . . . . eliminate parentheses
... 0 = 2x -10 . . . . . . . . . . subtract x²+x
... 0 = x -5 . . . . . . . . . . . . divide by 2
... 5 = x . . . . . . . . . . . . . . . add 5
Step-by-step explanation:
-2x,7x and 2x,x3
look for the same variables or look if they both have a negative or a positive without a variable , example: -2.345 has the same terms as -5.99
Step-by-step explanation:
=( 5 + 1 )2 - ( 12 + 32 ) + 3
=6 * 2 - 44 + 3
=12 - 44 + 3
= -29
Answer:
The correct answer is B (The universe was hotter previously than it is now
The slope of the line as shown in the graph attached is 7/3
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
A variable can either be independent or dependent. A dependent variable depends on other variable while an independent variable does not depend on other variable.
A linear equation is in the form:
y = mx + b
Where m is the rate of change (slope) and b is the y intercept.
The slope of a line = vertical rise / horizontal run
From the image:
Slope = rise / run = 7/3
