Answer:
y = -2x - 5
Step-by-step explanation:
y = -2x + b
- To find the y-intercept, plug the values of the variables.
5 = -2(-5) + b
5 = 10 + b
- Subtract 10 from both sides.
-5 = b
SO what you need to do is:
<span>Start with |f(x) - 3| < 0.4
and plug in f(x) = x+1
to get
|f(x) – 3| < 0.4
|x+1 – 3| < 0.4
|x - 2| < 0.4
-0.4 < x - 2 < 0.4
-0.4+2 < x < 0.4+2
1.6 < x < 2.4
So delta would be 2.3
Hope this is what you were looking for

<em>Coplanar</em> means "lying on the same plane," while <em>colinear </em>means "lying on the same line." In this problem, all four points A, B, C, and D are coplanar - they all lie on the plane 
- so we just need to find the points that lie on the same line. Though points C and B <em>would </em>be colinear if there was a line drawn between them, there's no such line in this problem, so we can rule that out. We notice one line drawn on the plane, and points A, C, and D lying on it, so we can say that points A, C, and D are both coplanar and colinear.
Answer:
7. C
8. B
9. B
Step-by-step explanation:
7: A proper fraction is a fraction where the numerator is greater than the denominator. Choice <em>a</em> is a decimal, not a fraction. Choice <em>b</em> is a fraction, but its numerator is equal to its denominator. Choice <em>d</em> is also a fraction, but its denominator is greater than its numerator. Choice <em>c</em> is correct, because it is a fraction where its numerator is greater than its denominator.
8. A decimal fraction has denominators like 10, 100, 1000, as so on. It is a fraction.
9. A fraction is equal to the numerator divided by the denominator. When the numerator is equal to the denominator, the value of the numerator divided by the denominator is 1.
