I am assuming you meant to write b(x) = x-4.

(b \circ a)(x)=b(a(x))=b(3x+1)=(3x+1)-4=\boxed{3x-3}

Since this is a linear function, the domain is all real numbers.

Which ordered pair is a solution of the equation? − 7 x + 3 y = 2 −7x+3y=2
Viefleur [7K]

Answer:

Hello There. ☆~\---___`:•€`___---/~☆ The correct answer is C. Both (1,3) and (-2,-4).

To check whether (-2,-4) is a solution of the equation let's substitute x= -2 and y= -4 into the equation:

-7x+3y=2

-7*(-2)+3*(-4)=2

14-12=2

2=2

Do the same thing with (1,3)

-7x + 3y = 2

-7 * 1 + 3 * 3 = 2

-7 + 9 = 2

2 = 2.

Hope It Helps!~ ♡

Which is the answer
sukhopar [10]

Answer:

Inverse property

Step-by-step explanation:

The definition of the inverse property is to add to get a result of zero. Since we are adding the inverse of each term to get a result of zero each time, we are using the inverse property.

UkoKoshka [18]

Answer:

3a:20d+35

3b:35u+49q+56

4a:15+20t

4b:96k+120t+84

5a:24t+108m+60

5b:56q+28b+35

6a:14q+10w+24

6b:54v+99+27t

7a:16g+24+24c

7b:30a+55+50d

(i think thats what they are but the picture is small so its kind of hard to see)

Step-by-step explanation:

(since theres 10 total ill just give an example on how i solved 5a)

5(4d+7)

simplify into: (5•4d)+(5•7)

multiply: (20d)+(35)

since you do not know what d is, you cannot add them

remove parentheses once done:20d+35

(you don't need parentheses since multiplication come before addition but its easier to just use them)

The result of our calculations about the rate and time are:

  • r=d/t
  • 200000m/hr
  • 200km/hr
  • km/hr

<h3>What is rate?</h3>

Rate can be regarded as the given object with respect to time.

falcon flies= 800,000 meters

t= 4 hours

We were given the  formula as (d = rt)

d= distance

r = rate

t = time

We can make our calculations as:

part a:

r=d/t

part b:

falcon's rate in meters per hour = 800,000 meters / 4 hours = 200000m/hr

part c:

falcon's rate in kilometers per hour=(200000m/hr *(1/1000)=200km/hr

part d:

km/hr
