Well, if there are 33 children in class, and 5 children have dogs, then to find out how many have cats, you subtract 5 from 33. It looks like this:

33-5 = 28

Therefore, 28 students have cats.

On a coordinate plane, 2 exponential fuctions are shown. Function f (x) decreases from quadrant 2 into quadrant 1 and approaches
Gala2k [10]

Answer:

g(x)=6(3)^x

Step-by-step explanation:

We are given  that

f(x)=6(\frac{1}{3})^x

Function f decreases from quadrant  2 to quadrant 1 and approaches  y=0

It cut the y- axis at (0,6) and passing through the point (1,2).

Function g(x) approaches y=0 in quadrant 2 and increases into quadrant 1.

It passing through the point (-1,2) and cut the y-axis at point (0,6).

Reflection across y- axis:

Rule of transformation is given by

(x,y)\rightarrow (-x,y)

Using the rule then we get

g(x)=6(\frac{1}{3})^{-x}=6(3)^x

By using

x^{-a}=\frac{1}{x^a}

Substitute x=-1

g(-1)=6\times (\frac{1}{3})=2

Substitute x=0

g(0)=6

Therefore,g(x)=6(3)^x is true.

Solve the system of equations using the substitution method. 2x+8y=4 x=−3y+5
goldenfox [79]
Since x=-3y+5, substitute x for -3y+5. 

2(-3y+5)+8y=4

Distribute. 

-6y+10+8y= 4

2y+10= 4

Subtract 10 on both sides. 

2y=-6

Divide by 2.

y=-3

Plug in y=-3. 

x=-3(-3)+5
x= 9+5
x=14

(14,-3)

We can check this. 

2(14)+8(-3)=4
28-24=4
4=4 <== this works

I hope this helps!

What is the sum of the geometric sequence-1 6 -36 yes there are 7 terms
vagabundo [1.1K]

Answer:

-39991'

Step-by-step explanation:

We require the sum of 7 terms of the G.S.  -1, 6, -36  .....

The common ratio r = 6/-1 = -6 and the first term = -1.

Sum of n terms = a1 . (r^n  - 1) / (r - 1)

Sum of 7 terms = -1 * (-6)^7 - 1)  / (-6 - 1)

=  -1 * 39991

= -39991 (answer).
