Are these terms alike or unlike: 2xy and 2xyz

Answer:
Unlike
Step-by-step explanation:

Simplify 5a – (2a + 6)
Answers
Answer:
Step-by-step explanation:
Add '-2a' to each side of the equation.
5a + -2a = -6 + 2a + -2a
Combine like terms: 5a + -2a = 3a
3a = -6 + 2a + -2a
Combine like terms: 2a + -2a = 0
3a = -6 + 0
3a = -6
Divide each side by '3'.
a = -2
Simplifying
a = -2
5a -2a -6
3a -6

Graph the line with the equation y=

Answers
Step-by-step explanation:
look at the attachment
.....
The graph of the linear equation is plotted and y = ( -1/5 )x + 4
Given data ,
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
On simplifying , we get
y = ( -1/5 )x + 4
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = -1/5
And , the y-intercept of the graph of the line is when x = 0
So , when x = 0
y = ( -1/5 ) ( 0 ) + 4
y = 4
Hence , the equation of line is y = ( -1/5 )x + 4

Answers
Answer:
$454220
Step-by-step explanation:
Given: B = P[tex](1 + \frac{r}{n} )^{nt}[/tex]
But, B is the future amount
P is the present amount = $2350
r is the rate = 1.1%
n is the number of compounding per year = 12
t is the number of years = 5
So that;
B = 2350[tex](1+\frac{1.1}{12}) ^{12*5}[/tex]
= 2350[tex](1.0917)^{60}[/tex]
B = 2350 x 193.2852
= 454220.22
B = $454220
Thus, her ending balance after 5 years is $454220.
