hope it helps

-10(b - 9)        distribute by multiply -10 × b = -10b and -10 × -9 = 90

-10b + 90, final answer

Answer:

D

Step-by-step explanation:

Binomial means that it will have two terms, so by process of elemination, we are only left with C and D. Degree would be the power, and D is the only one that has a power of 2.

Complete question − How many kilometres did they travel by bus and by bicycle.

Answer:George and carmen traveled by bus in 135km and by bikein 215km

Step-by-step explanation:

Total Miles traveled  =   350 miles  

Let Number of kilometres they traveled with bus  = x

and Let Number of kilometres they traveled with bike = x + 80

so that the total distance traveled with bus and bike be expressed as

x + x + 80 =   350 miles  

2x + 80 =   350 miles  

2x =   350 − 80

2x =270

x=135

George and Carmen traveled by bus in 135km  

and by bicycle=x + 80 = 135 km + 80 =215km

Answer:

68% i think yeah?

The percent of bags of cookies will contain between 60 and 68 cookies is 68.29%.

A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean.

[tex]\mu[/tex]= 64,   [tex]\sigma[/tex]= 4,

[tex]Z_1[/tex]= [tex]X_1[/tex] - [tex]\mu[/tex]/  [tex]\sigma[/tex]

  = 60-64/4

  = -1

again,

[tex]Z_2[/tex]= [tex]X_2[/tex] - [tex]\mu[/tex]/  [tex]\sigma[/tex]

  = 68-64/4

  = 1

Thus, P( 60<X<68)

= p(-1<Z<1)

= 0.6829

= 68.29%

I know because i found the area of Peter and Jill's net and divided the area of Jills net by peters net

Step-by-step explanation:

Area = height x width

Area pf soccer net in Peter's back yard = 51/2 x 4 = 22 feet^2

Area of jill's soccer net = 51/2 x 16 = 66 feet squre

difference in area = 66/22 = 3

Answer:

X=1.5

Y= -0.5

Step-by-step explanation:

3X+Y=4

Y=4-3X

5X-7Y=11

5X-7(4-3x)=11

5X-28+21X=11

26X=11+28

26X=39

X=1.5

Y=4-3(1.5)

Y=4-4.5=(-0.5)

Answer:

x=1.5  y=-0.5

Step-by-step explanation:

first we want to rearrange one of the equations

we will rearrange 3x+y=4 we will do this by subtracting 3x from both sides

y= -3x+4

and replace y in the second equation 5x-7y=11

5x -7(-3x+4)=11

we will distribute -7

5x+21x-28=11

solve for x

26x=39

x=1.5

and solve y by substituting x into one of the equations

y= -3(1.5)+4

y=-0.5

Answer:  I'm gonna go with letter A

Is the relation {(1, 3), (–4, 0), (3, 1), (0, 4), (2, 3)} a function? Why or why not? No, the range value 3 corresponds to two domain values, 1 and 2. ... No, there is no value in the domain that corresponds to more than one value of the range.  Jun 13, 2017

Step-by-step explanation:  The answer is either letter B or letter D.

Determine if the relation is a function.

The relation is a function.

Answer:

D

Step-by-step explanation:

We say a relation between two sets is a function if every value in the first set (the domain) corresponds to exactly one value in the second (the range). This doesn't mean we can't have two different domain values pointing to the same range value, but it does mean we can't have on domain value pointing to two different range values.

Our relation here is a function, since each domain value only points to one range value, so our answer is D.

Answer:

x= -3

y= -9

Step-by-step explanation:

Y-4X =3 ; 2x-3y=21

Y= 3+ 4x

2x -3( 3+4x)= 21

2x- 9- 12x= 21

-10x -9= 21

-10x -9+9= 21+9

-10x = 30

X= 30/-10= -3

Y= 3+4x = 3+ 4* (-3)= 3-12= -9

Answer:

any coordinate outside the parabola is a reasonable answer.

Step-by-step explanation:

test the solution (0, 0) and if if that number is greater than 0 then the rest of the points outside on the inside are.

x = 0

y = 0

(0)^2 - 2(0) - 3 = -3

-3 is less than 0 so (0, 0) is not a possibility so any coordinate outside the parabola is a reasonable answer.

Answer:

I think it is    4/3

Step-by-step explanation:

Answer:

x = 5.

y = -2

Step-by-step explanation:

y = x - 7

2x + y = 8

substitute the first equation into the second

2x + (x -7) = 8

2x + x - 7 = 8

3x - 7 = 8

3x = 8 + 7

3x/3 = 15/3

x = 5.

substitute 5 in the second equation

y = 5 - 7

y = -2
