(3x + 2) ( x-2) Simplify expressions? 2/3 x 1/8 ? or 3 3/4 divided by 1 1/2 how do u simplify?
Answers
3x (x-2) + 2(x - 2) *distributive property of multiplication
3x² - 6x + 2x - 4
3x² - 4x - 4 = 0
2/3 * 1/8 = 2*1 / 3*8 = 2/24 :
2/24 can be simplified into 1/12.
divide 2 by 2 to get 1. divide 24 by 2 to get 12.
3 3/4 ÷ 1 1/2
convert mixed fractions to fractions.
3 3/4 = (3*4+3)/4 = 15/4
1 1/2 = (1*2+1)/2 = 3/2
15/4 ÷ 3/2 ⇒ 15/4 * 2/3 = 15*2 / 4*3 = 30/12
30/12 can be simplified to 10/4
30 divide by 3 to get 10. 12 divide by 3 to get 4.
10/4 can be simplified to 5/2
10 divide by 2 to get 5. 4 divide by 2 to get 2.
5/2 can be a mixed fraction of 2 1/2.
30/12 = 2 6/12 can be simplified to 2 1/2.

do the parenthasees first
-10y+18=-15y+21+5y
group like terms (y with y and numbers with numbers)
-10y+18=-10y+21
add 10y to both sides and you get
18=21 which is false
so no solution
6. 8(t+2)-3(t-4)=6(t-7)+8
do the parenthasees
8t+16-3t+12=6t-42+8
group like terms
5t+28=6t-36
subtract 5t from both sides
28=t-36
add 36 to both sides
64=t
7. do the parenthasees first
20+8x-5=9x+21
add like terms
15+8x=9x+21
subtract 8x from both sids
15=x+21
subtract 21 from both sides
x=-6
8. distribute the parenthasees
12x-48+3=15
add like terms
12x-45=15
add 45 to both sides
12x=60
divide both sides by 12
x=5

The required property of the even function that is seen in the graph is f(-x) = f(x).
What are functions?
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
here,
In the given graph,
The domain of the function is (-∞, ∞),
While the range is all positive real numbers, that implies that the function does not have negative real value, So the function shows that property as,
for all x, f(x) is positive real number,
So,
f(x) = f(-x)
Thus, the required property of the even function that is seen in the graph is f(-x) = f(x).

f(x) = f(-x).
The value of the function at x values is the same as the value of the function of -x values.
