Problem 1.1 Solve this equation: 2(x + 5) = 3x + 1

Tamiku [17]

Answer:

x = 9

Step-by-step explanation:

Distribute

2x+2*5=3x+1

2x+10=3x+1

Subtract 3x from both sides

-x+10=1

Subtract 10 from both sides

-x=-9

Multiply both sides by -1

x=9

Simplify -3(x + 3) + 4x

Nadusha1986 [10]

Answer: x2 + 34x - 13

Step-by-step explanation:

STEP

Trying to factor by splitting the middle term

1.1 Factoring x2+34x-13

The first term is, x2 its coefficient is 1 .

The middle term is, +34x its coefficient is 34 .

The last term, "the constant", is -13

Step-1 : Multiply the coefficient of the first term by the constant 1 • -13 = -13

Step-2 : Find two factors of -13 whose sum equals the coefficient of the middle term, which is 34 .

-13 + 1 = -12

-1 + 13 = 12

Observation : No two such factors can be found !!

Conclusion : Trinomial can not be factored

Final result :

x2 + 34x - 13

Identify and solve the inequality that represents how many $20 bills, n, you can withdraw from the account without going below t

Alex Ar [27]

Answer:

$100 + 20n \leq 230$

$n \leq 6$

Step-by-step explanation:

Given

$Balance = \$230.00$

$Minimum = \$100$

$Withdrawal = \$20\ each$

Required

Represent using an inequality and solve

Let the number of dollars be represented by n

If 1 withdrawal is $20 bill

n withdrawals would be $20n bills

The total withdrawal and the minimum balance must be less than or equal to the available balance.

So, this gives

$Minimum + Total\ Withdrawal \leq Available\ Balance$

Substitute values for each of these

$100 + 20n \leq 230$

Solving for n

$20n \leq 230 - 100$

$20n \leq 130$

Divide through by 20

$n \leq 6.5$

But n can not be decimal because it represents number of dollar bills , which must always be an integer.

So, we round down the value of n

$n \leq 6$

Graph y=−4/7x+1 . Use the line tool and select two points on the line.

Sergeeva-Olga [200]

Find two points by giving x an y values and solving the equation:

y = -4/7x +1

1 = -4/7x +1, x =0

First point is (0,1)

5 = -4/7x +1, x = -7

Second point is (-7,5)

Now plot those two points on the graph and draw a line through them
