Answer:

x² + 2x - 48

Step-by-step explanation:

Given

(x - 6)(x + 8)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x + 8) - 6(x + 8) ← distribute both parenthesis

= x² + 8x - 6x - 48 ← collect like terms

= x² + 2x - 48

A.) (-3,12)
B.) (-3,13)
C.) (0,4)
D.) (-1,7)

Answers

Answer:

(D)(-1,7)

Step-by-step explanation:

We want to solve for x and y in the simultaneous equation

3x+y=4

2x+y=5

Subtract Equation 2 from Equation 1

x=-1

Substitute x=-1 into any of the equations to solve for x.

3x+y=4

3(-1)+y=4

-3+y=4

y=4+3=7

Therefore: (x,y)=(-1,7)

3x + y = 4
2x + y = 5....multiply by -1
--------------
3x + y = 4
-2x - y = -5 (result of multiplying by -1)
-------------add
x = -1

3x + y = 4
3(-1) + y = 4
-3 + y = 4
y = 4 + 3
y = 7

solution is (-1,7)

Maria's family drove 140 miles to her grandparents' house and averaged 56 mi/h on the way there. On the return trip, they averaged 50 mi/ hr. What was the total time Maria's family spent driving to and from her grandparents' house? A. 2.5 h B. 2.6 h C. 5.2 h D. 5.3 h

Answers

The total time Maria's family spent driving to and from her grandparents' house is option D 5.3 hours.

  • The calculation is as follows;

To grandparents house:

= 140/ 56

= 2.5 hours

And,

Return trip :

=140/ 50

= 2.8 hours

Now

Total time is

=  2.8+2.5

= 5.3 hours

Answer: i think its the first one 2/3

Answer:

2/3

Step-by-step explanation:

it starts off as 2:3 right? so the 3 is light soy sauce. if you want to turn the right soy sauce into 1 cup you have to divide 3 bye 3 which gives you one. then you also divide by 3 on the other side. that would be 2 divided by 3. 2 divided by 3 is the same as 2/3. so your answer is 2/3.

A chess club has 500 members but is losing 30 members each year. A computer club has 150 members and is gaining 20 members per year. Write and solve an equation to find the number of years it will take for the two clubs to have the same number of members.

Answers

Answer:

7 years

Step-by-step explanation:

Given: A chess club has 500 members but is losing 30 members each year. A computer club has 150 members and is gaining 20 members per year

To Find:  Write and solve an equation to find the number of years it will take for the two clubs to have the same number of members

Solution:

Total members in chess club= 500

chess club loosing members each year = 30

Number of members in chess club in year \text{x}

                                                                500-30\text{x}

Total members in Computer club= 150

chess club gaining members each year = 20

Number of members in chess club in year \text{x}

                                                                150+20\text{x}

Now,

When chess club and computer club have equal number of members

                     500-30\text{x}= 150+20\text{x}

                     500-150=30\text{x}+20\text{x}

                     350=50\text{x}

                     \text{x}=7

So,

It will take 7 years for two clubs to have the same number of members.

Well for this a t-chart type of graph would help but here's how you can do it:

key: ChC = chess club
       CmC = computer club

ChC = 500 members        ChC = losing 30/yr
CmC = 150 members        CmC = gaining 20/yr

year 1 :     ChC     CmC
members: 470   /   170

or.... you can scrap that, here's the simpler version : 
500 - 30x = 150 +20x

solution: x = 7

Hope this helps!

Arrange these numbers from least to greatest: -5/8, -7/9, -4/5, -3/7 A. -7/9 -5/8 -3/7 -4/5
B. -4/5 -7/9 -5/8 -3/7
C. -4/5 -5/8 -7/9 -3/7
D. -3/7 -4/5 -5/8 -7/9

Answers

for this question, the easiest way is to find the decimal for each fraction. 
so you can say: 
-5/8 = -0.6 
-7/9 = -0.7 
-4/5 = -0.8 
-3/7 - -0.4 
and because they are all negative numbers so from the least to the greatest will be: 
-4/5 < -7/9 < -5/8 < -3/7 
so the answer is B :)))
i hope this is helpful
