Answer:
C. jump discontinuity at x=-2
Step-by-step explanation:
At x=-2, you have to lift your pencil to keep drawing the graph. That means there's a jump discontinuity there.
This function has a jump discontinuity at x = -2.
__
<em>Additional comments</em>
At x=3, there is no discontinuity in the function. The <em>derivative</em> of the function has a discontinuity there, as there is an abrupt change in slope at that point.
If left and right limits exist and are the same at a point, but the graph is not defined at that point, then a <em>removable</em> discontinuity exists. All that is needed to fill the hole is to define the function at that point.
Answer: -20 1/12
Step-by-step explanation:
-8 + -11 = -19
-3/4 + -1/3 = -1 and 1/12
so -19 + -1 and 1/12 = -20 and 1/12
Answer:
x= -6 | I only have an answer for #7 but you should use a website called Symbolab :)
Step-by-step explanation:
x+16+x+12+2x+15=19
<em>group like terms: </em>
4x+43=19
<em>subtract 43 from both sides:</em>
4x+43=19
-43 -43
<em>simplify</em>:
4x=-24
<em>divided both sides by 4:</em>
x=-6
Given:
3 teaspoons of salt for every 5 cups of flour.
How much salt is needed for 15 cups of flour?
This is a proportion problem:
a/b = c/d where ad = bc
3/5 = x/15
3*15 = 5x
45 = 5x
45/5 = x
9 = x
C. 9 teaspoons of salt is needed for 15 cups of flour.
3/5 = 9/15
3*15 = 5*9
45 = 45
