Original System: x - 2y = 0; 5x + 2y = 24

In order to graph this system, you need to find the slope of each line and the y intercept of each line. The easiest way to do this is to put both equations into slope intercept form, which is y = mx + b

x - 2y = 0
- x - x
-------------------
2y = -x + 0
------ ---- ----
2 2 2

y = -1/2x

For this equation, the slope is 1. The x intercept is 0.

5x + 2y = 24
- 5x - 5x
------------------------
2y = -5x + 24
------ ------ ------
2 2 2

y = -5/2x + 12

In this equation, the slope is -5/2 and the y intercept is 12.

When you plug in these equations on Desmos, look at the exact point where the lines intersect. This will be your final answer to the system of linear equations.

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

−4.2(−2.8+4.5) I think I know what the answer is but I just want to be 100% sure. Please solve this and tell me your answer. I

Talja [164]

Answer:

-7.14

Step-by-step explanation:

Evaluate

−4.2(−2.8 + 4.5)

Open parenthesis

(-4.2 * -2.8) + (-4.2 * 4.5)

= (11.76) + (- 18.9)

= 11.76 - 18.9

= -7.14

NOTE:

Negative (-) × negative (-) = positive (+)

Positive (+) × positive (+) = positive (+)

Negative (-) × positive (+) = negative (-)

Positive (+) × negative (-) = negative (-)
