When translating the phrase "twice the quantity of four more than three times a number"on students wrote the expression 2*3x+4

1 answer:

It is wrong because the equation is missing parentheses around the sum

When it says "the quantity of..." it always means parentheses. The correct equation is 2(3x+4)

Which equation has a graph that passes through the points at (0,5) and (-3,-4)?

Roman55 [17]

Answer:

$y = 3x + 5$

Step-by-step explanation:

We are asked the equation of the graph which passes through the points at (0,5) and (-3,-4).

Now, we know that the equation of a straight line passing through the points ( $x_{1},y_{1}$ ) and ( $x_{2},y_{2}$ ) is given by

$\frac{y - y_{1}}{y_{1} - y_{2}} = \frac{x - x_{1}}{x_{1} - x_{2}}$ .

So, in our case ( $x_{1},y_{1}$ ) ≡ (0,5) and ( $x_{2},y_{2}$ ) ≡ (-3,-4)

Therefore, the equation of the straight line will be

$\frac{y - 5}{5 - (- 4)} = \frac{x - 0}{0 - (- 3)}$

⇒ $y - 5 = \frac{9}{3}x$

⇒ $y = 3x + 5$ (Answer)

You have $55 in your bank account. Each week you deposit $8 from your allowance and $15 from your paycheck. The equation b=55+(

scoundrel [369]

<h3>After 6 weeks from now you will have $190 in your bank account</h3>

Solution:

Given that,

You have $55 in your bank account

Each week you deposit $8 from your allowance and $15 from your paycheck

The equation that gives the amount b in your account after w weeks is:

b = 55 + (15 + 8)w

How many weeks from now will you have $190 in your bank account ?

b = 190

w = ?

Therefore,

190 = 55 + (15 + 8) w

190 = 55 + 23w

23w = 190 - 55

23w = 135

Divide both sides by 23

$w = 5.869 \approx 6$

Thus after 6 weeks from now you will have $190 in your bank account
