Graph the function f( x ) = |x+2| - 3
stepladder [879]

Answer:

Find the attached

Step-by-step explanation:

To graph the given function, we would need to obtain pairs of points (x, f(x)). We can let x be;

-5, -4, -3, 3, 4, 5

we simply substitute each value of x in the given function to obtain the value of the function corresponding to the given x value;

when x = -5, f(-5) =  |-5+2| - 3 = 0

when x = -4, f(-4) =  |-4+2| - 3 = -1

when x = -3, f(-3) =  |-3+2| - 3 = -2

when x = 3, f(3) =  |3+2| - 3 = 2

when x = 4, f(4) =  |4+2| - 3 = 3

when x = 5, f(5) =  |5+2| - 3 = 4

The graph of the function is as shown in the attachment below.

Catherine used the two points and the right triangle shown to find the slope of the line Catherine found the slope to be 1/10. I
blagie [28]

Answer:

Catherine is not correct (see the explanation)

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

we know that

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

the two points from the graph are

(4,40) and (7,70)

substitute the values in the formula

m=\frac{70-40}{7-4}\\m=\frac{30}{3}\\m=10

therefore

If
levacccp [35]
To solve this problem you can do a proportion
\frac{x}{215}  =  \frac{35\%}{100\%}
to find 'x', we have to cross multiply the numbers.
215 \times 35
and
100 \times x
this will get you
7525 = 100x
to get 'x', we have to divide by 100 on each side
\frac{7525}{100}  =  \frac{100x}{100}

your answer will be
75.25 = x
so, Chris must raise 75.25 dollars by himself

Find the sum of the given vectors and illustrate geometrically. [-1,4],[6,-2]
cricket20 [7]

Answer:

The sum of vectors is <5,2>.

Step-by-step explanation:

The given vectors are <-1,4> and <6,-2>.

We need to find the sum of the given vectors and illustrate geometrically.

Plot the point (-1,4) on a coordinate plane and draw a vector <a> from (0,0) to (-1,4).

Plot the point (6,-2) on a coordinate plane and draw a vector <b> from (0,0) to (6,-2).

Now complete the parallelogram and the diagonal represents the sum of both vectors.

The end point of the diagonal is (5,2). It means sum of vectors is <5,2>.

Check the sum of vectors:

+==

Therefore, the sum of vectors is <5,2>.
