When competing the square, you want to have
${b}^{2}$
at the end, and using the fact that the x term and coefficient are really
$2bx$
, we see that the third option is the most efficient way to start

The computer store pays its employees $150 per day plus a commission of 15% of their sales. Teagan wants to make at least $450 t

Savatey [412]

The equation 0.15 x + 150 ≥ 450 will help Teagan determine how much he has to sell today ⇒ A

Step-by-step explanation:

The given is:

The computer store pays its employees $150 per day plus a commission of 15% of their sales
Teagan wants to make at least $450 today

We need to find which equation will help Teagan to determine how much he has to sell today

Assume that he has to sell by $x today

∵ The store pays $150 per day plus a commission of 15%

of their sales

∵ Teagan's total sales = x

- Multiply 15% by x, then add the product by 150

∴ Teagan makes = 15% × x + 150

∵ 15% × x = $\frac{15}{100}$ × x = 0.15 x

∴ Teagan makes = 0.15 x + 150

∵ Teagan wants to make at least $450 today

- At least means ≥

∴ Teagan makes ≥ 450

- Substitute Teagan makes by 0.15 x + 150

∴ 0.15 x + 150 ≥ 450

The equation 0.15 x + 150 ≥ 450 will help Teagan determine how much he has to sell today

Priya has picked 1 1/2 cups of raspberries which is enough for 3/4 of the cake how many cups does she need for the whole cake

Zina [86]

Answer:

So Priya need $2$ cups of raspberries for the whole cake.

Step-by-step explanation:

Given data;

$1\frac{1}{2}=\frac{3}{2}$ cups of raspberries which is enough for $\frac{3}{4}$ of the cake.

For making $\frac{3}{4}$ of the cake need $\frac{3}{2}$ cups of raspberries.

For making $1$ cake need $\frac{\frac{3}{2}}{\frac{3}{4}}$ cups of raspberries.

For making $1$ cake need $\frac{3}{2} \times \frac{4}{3}=2$ cups of raspberries.

∴ Priya need $2$ cups of raspberries for the whole cake.

Put the equation in standard form y=-4/5x+2

sp2606 [1]

Answer:

4x +5y = 10

Step-by-step explanation:

Standard form of an equation is Ax +By = C

y=-4/5x+2

Add 4/5 x to each side

4/5 x +y=-4/5x+ 4/5x+2

4/5 x + y = 2

Now we don't have fractions in A ,B or C

So Multiply by 5

5(4/5 x + y) = 2*5

Distribute

4x +5y = 10

What does b represent in the equation of a line in the form y = mx + b?

Dvinal [7]

B is called "the vertical intercept" and is the value of y when x = 0. Something like an initial value!
