Let us solve this by substitution ;

x = y + 6
y = -2 - x

Now, we substitute the value of y in first equation. This gives us;

x = (-2-x) + 6

x = 4 - x

thus, 2x = 4

thus, x = 2.


Substituting the value of x in equation of y,

y = -2 - x
y = -2 - 2
thus, y = -4.


Thus, the solution is x = 2 , y = -4

Can someone help me on the last question?
BabaBlast [244]

Answer:

I like saying rise over run because it helps me remember that rise means how many units you move up or down from point to point which on a graph would be a change in the y values. Also that run means how far left or right you move from point to point which on the graph would mean a change of x values.

Because Earth's rotation is gradually slowing, the length of each day increases: The day at the end of 1.0 century is 1.0 ms lon
harina [27]

Answer:

14.6 minutes

Step-by-step explanation:

Since there is a 1 ms increase per day and there are 365 days a year, the time increase per year is 1 ms/day × 365 days/year = 365 ms/year.

So, in 24 centuries, there are 24 × 1 century = 24 × 100 years = 2400 years (since  1 century = 100 years)

So, the total of the daily increase in time in 24 centuries is time increase per year × 24 centuries

= 365 ms/year × 2400 years

= 876000 ms

= 876 s

= 876 s/60s

= 14.6 minutes

What is the value of this expression when a = 3 and b = -2?
weqwewe [10]

The first step: Simplify the expression with:

\dfrac{x^n}{x^m}=x^{n-m}\\\\(xy)^n=x^ny^n\\\\(x^n)^m=x^{nm}\\\\x^{-n}=\dfrac{1}{x^n}

\left(\dfrac{3a^{-2}b^6}{2a^{-1}b^5}\right)^2=\left(\dfrac{3}{2}a^{-2-(-1)}b^{6-5}\right)^2=\left(\dfrac{3}{2}a^{-1}b^1\right)^2\\\\=\left(\dfrac{3}{2}\right)^2(a^{-1})^2b^2=\dfrac{9}{4}a^{-2}b^2=\dfrac{9b^2}{4a^2}

The second step: Put the values of a = 3 and b = -2 to the expression:

\dfrac{9(-2)^2}{4(3)^2}=\dfrac{(9)(4)}{(4)(9)}=1

Algebra 2 help please!
mezya [45]

Answer:

h(-8)=1 and -12

Step-by-step explanation:

In this problem, we will need to plug in "-8" for any x we see.

h(-8)=|-8+4|-3

h(-8)= |-4|-3

h(-8)=4-3

h(-8)=1

Yay! We got an answer. However, since there is an absolute value, there is another case -- if x is negative.

h(-8)=-8-4

h(-8)=-12
