Cost of tape: 4.95
no. of tape : x
budget : 37.85
4.95x < 37.85
+++
4.95x < 37.85
<u>÷4.95 ÷4.95</u>
x < 7.65
* you have to buy tapes that are less than 7.65
Assuming you bought 7 tapes.
4.95x < 37.85
4.95(7) < 37.85
34.65 < 37.85 *inequality is correct
If you buy more than 7 tapes, then, the cost of the tapes will be more than your budget. making the inequality incorrect.
Answer:
- y -3 = -4(x -0) or y -3 = -4x
- y = -4x +3
Step-by-step explanation:
The point-slope form of the equation of a line with slope m through point (h, k) is ...
y -k = m(x -h)
Fill in the given values:
y -3 = -4(x -0) . . . . point-slope form of the equation of the line
__
To get this to slope-intercept form, you want to rearrange it to ...
y = mx + b
Eliminating parentheses get you ...
y -3 = -4x
Adding 3 puts the equation in the desired form:
y = -4x +3
