Solve each

3x+5≤-1
minus 5 both sides
3x≤-6
divide 3
x≤-2

other

-2x-7≥5
add 7 to both sides
-2x≥12
divide both sides by -2 and flip sign
x≤-6


we got

x≤-2 or x≤-6
so since x≤-6 is actually inside the solution set of x≤-2, just shade from x≤-2
put dot at x=-2 and shade to left

Irina18 [472]

The function P(t)=5(b)^t, The initial number of fish species released was 5.

The function S(t)=152(1.045)^t, The growth rate is 4.5%

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

An exponential function is in the form:

y = abˣ

Where a is the initial value and b is the multiplication factor.

Given the function P(t)=5(b)^t, The initial number of fish species released was 5.

The function S(t)=152(1.045)^t, The growth rate is 4.5%

Find an equation of the plane that is parallel to the xz-plane and is located 11 units to the right of the xz-plane in standard
mina [271]

Answer:

y = 11

Step-by-step explanation:

Since our plane is parallel to the xz plane, the x and z are independent of each other, i.e. they could be anything. So xz plane has an equation of y = 0. So if this plane is located 11 units to the right of the xz plane then its equation must be y = 11.
