Answer:

x < 80000

Step-by-step explanation:

3600 + 1.02x < 2000 + 1.04x \\  \frac{ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  - 1.04x <  \:  \:  \:  \:    \:  \:  \:  \:  \:  \:  \:  \:  \:  - 1.04x}{3600 - 0.02x < 2000}  \\  \\ 3600 - 0.02x < 2000 \\  \frac{ - 3600 \:  \:  \:  \:  \:  \:  \:  \:  \:  <  - 3600}{ - 0.02x <  - 1600}  \\  \\  \frac{ - 0.02x}{ - 0.02}   <  \frac{ - 1600}{ - 0.02}  \\  \\ x < 80000

Suppose that the functions g and h are defined for all real numbers r as follows. gx) -4x +5 h (x) = 6x write the expressions fo
aleksandr82 [10.1K]

Answer: Our required values would be -10x+5, 2x+5 and -25.

Step-by-step explanation:

Since we have given that

g(x) = -4x+5

and

h(x) = 6x

We need to find  (g-h)(x) and (g+h)(x).

So, (g-h)(x) is given by

g(x)-h(x)\\\\=-4x+5-6x\\\\=-10x+5

and (g+h)(x) is given by

g(x)+h(x)\\\\=-4x+5+6x\\\\=2x+5

and (g-h)(3) is given by

-10(3)+5\\\\=-30+5\\\\=-25

Hence, our required values would be -10x+5, 2x+5 and -25.

When asked to write a point slope equation for a line passing through the points (-4,-7) and (3,2) a student wrote y-2=-9/7(x-3)
AleksAgata [21]
First let's find the slope
Slope formula: 
\frac{y_2-y_1}{x_2-x_1} =slope
Given the two coordinates: 
(-4,-7) (3,2) 
 x1,y1  x2,y2

Plug these numbers into the formula
\frac{2-(-7)}{3-(-4)} = \frac{9}{7}
In this case the mistake that was made was that the student wrote the slope negative instead of positive
Final answer: 
<span>y-2=9/7(x-3)</span>

If a side of the field is 9/10 mile and 1/2 mile what is the length of the field
Katyanochek1 [597]

Answer:

<em>The field is 1 and 4/10 mile long.</em>

Step-by-step explanation:

If I understand the question:

(1/2) + (9/10) =

(5/10) + (9/10) = (14/10)

(14/10) is 1 and 4/10

The field is 1 and 4/10 mile long.
