Answer:

a 2(x+5)

b 5(x+3)

c 2(4x+3)

d 4(3x+2)

Step-by-step explanation:

find the greatest common fact for all of them

a 2

b 5

c 2

d 4

then divide them into both numbers

a x+5

b x+3

c 4x+3

d 3x+2

then add parentheses and

put the greatest common factor on both of them look at the answer above

-hope this helps :)

This equation shows how the cost of a charity gala depends on the number of attendees. d = 5.1a + 11.6 The variable a represents

aleksandr82 [10.1K]

$98.30=5.1a+11.6
98.30-11.6=5a+11.6-11.6
86.7=5a
86.7/5=5a/5
17.34=a
So only 17 people can attend

How would I do this problem?

kenny6666 [7]

If it's a geometric sequence then:

$a_1=27;\ a_2=27\\\\r=\dfrac{a_2}{a_1}\to r=\dfrac{27}{36}=\dfrac{3}{4}=0.75\\\\a_{n+1}=a_nr\\\\a_3=27\cdot0.75=20.25\ CORRECT$

We calculate the fourth and fifth term of the sequence:

$a_4=a_3r\to a_4=20.25\cdot0.75=15.1875\\\\a_5=a_4r\to a_5=15.1875\cdot0.75=11.390625$

Answer:

In year 4 15.1875 animals.

In year 5 11.390625 animals.

Write the points (-3,5) and (1,1) in slope-intercept form

Jobisdone [24]

Y=mx+b
m=slope
b=yint

find slope
slope between (x1,y1) and (x2,y2) is (y1-y2)/(x1-x2)

given
(-3,5) and (1,1)
slope=(5-1)/(-3-1)=4/-4=-1

y=-1x+b
find b
when x=1, then y=1
1=-1(1)+b
1=-1+b
add 1
2=b

y=-x+2
