Nadya [2.5K]

→ 1200 * 90

→ $108000

Tell whether the ordered pair (1,1) is a solution of the system of inequalities.
Dmitry [639]

Since 0 < y < 1.5, hence the coordinate (1,1) is a solution

<h3>A solution to the system of inequality</h3>

Given the following inequality expression

y>0

y< 2.5x - 1

Wee are to check if (1, 1) is a solution to the systen of equation

If x = 1

y < 2.5(1) - 1

Y < 2.5 - 1

y < 1.5

Since 0 < y < 1.5, hence the coordinate (1,1) is a solution

vivado [14]
Hello,

Let's solve this problem mathematically.

For first design...

f = 200 \times 15 = 3000

For second design...

s = 200 \times 55 = 11000

To use an entire budget for design she must order.

For first design

5800÷3000 = 1.93f

or
For second design

5800÷11000=0.52s

Hope this helps answer your question!

Which of the following is the equation of a line parallel to the line y = 4x + 1, passing throughout the point (5,1)?
snow_tiger [21]
The answer is A. When you put it into slope-intercept form it is the only equation that turns out parallel, and when you plug in the x value 5 you get the y value of 1, which means it passes through the point (5,1)
