40=3x+x^2<br><br> How do I find the answer to this

tamaranim1 [39]

Answer:

x = -8, x = 5

Step-by-step explanation:

This can be solved using Factorization method:

$40 = 3x + {x}^{2} \\ \\ \implies \: {x}^{2} + 3x - 40 = 0 \\ \\ \implies \: {x}^{2} + 8x - 5x- 40 = 0 \\ \\ \implies \: x({x} + 8) - 5(x + 8) = 0 \\ \\ \implies \: ({x} + 8) (x - 5) = 0 \\ \\ \implies \: ({x} + 8) = 0 \: \: or \: \: (x - 5) = 0 \\ \\ \implies \: x = - 8 \: \: or \: \: x = 5 \\ \\ x = - 8, \: \: 5$

Tamiko got a check for 109.60 and a small bonus check for 34.15.What is the net result of her transactions using the result from

lara31 [8.8K]

a) Net result of Tamiko's transactions = $143.75

b) Total amount she can save = $86.25

Step-by-step explanation:

Step 1 :

Given,

Amount Tamiko got in her first check = $109.60

Amount of the bonus check = $34.15

Fraction of the amount she wants to save = $\frac{3}{5}$

We need to find the net results of her transactions and the amount she will save

Step 2 :

The new result of her transactions can be computed by adding the amount she has received through both the check.

Total amount she received = 109.60 + 34.15 = 143.75

Total amount she can save = $\frac{3}{5}$ × 143.75 = 86.25

Step 3 :

Answer :

a) Net result of Tamiko's transactions = $143.75

b) Total amount she can save = $86.25

Take the equation: y = 520 + 14x and put each value from the table in for x and y.

100 = 520 + 14 * -30
100 = 520 + -420
100 = 100 When we get an answer like this where the numbers on both sides of the equation match, we know that this (x,y) point is a part of the solution to the function.

So, you would work through each line in the table. If they are all like the one above, the answer is Yes. If not, it is no.

A couple realizes a real estate financing of R $ 180,000.00, to be paid in 360 monthly installments, with an effective interest

Lilit [14]

Answer:

ANSWER: letter D

Step-by-step explanation:

In the tenth installment, the debit balance is, in reais, of

180000 - 9. 500 = 175500

The 1% interest on this amount results in:

1% . 175 500 = 1755

Thus, the tenth installment is, in reais, 500 + 1755 = 2255
