Which statement describes the graph?

Answers

Answer : D

From the given graph , we can see that

The graph crosses the y axis at 7

So y axis is (0,7)

The graph is increasing at first  and reaches (-2,8)  and then start  decreasing

The graph start increasing at x=-10  and goes on increasing till x= -2

then the graph start decreasing at x=-2  and goes in decreasing till x= 10

The graph crosses the y axis at (0,7), increasing from x=-10  to x=-2  and decreasing from x=-2 to x=10

Answer D is correct

Answer is d

Multiply. write the product as a mixed number 3×3/5

Answers

3 x 3/5

Steps in multiplying fractions:
3 is a fraction that is 3/1

3/1 * 3/5

1) multiply numerators: 3 * 3 = 9
2) multiply denominators: 1 * 5 = 5
3) simplify fraction:
3 x 3/5 = 9/5
9/5 = 1 4/5
Hi There!

To do this problem you must multiply the fraction!

Steps
1. Determine The number you multiply

2. first multiply 3*3

3. After you solve step two, you should get 9

4. You're answer should 9/5

5. Now change the answer to a mixed number

6. To do this you have to divide 5 by 9

7. you should get 1 R 4

8.  The one will be your whole number and the 4 will be your numerator, the denominator stays the same

9. You're final answer should be 1 4/5

So, 3*3/5 multiplied, will be 1 4/5

Hope This Helps!

Simplify

(2x^{2} - 5x + 3) - (-x^{2} + 4x - 5)

Answers

Answer:

3x^2 - 9x + 8

Step-by-step explanation:

To simplify:

  • Distribute the -1 into the second term.
  • Collect and combine like-terms (terms with the same variables or powers)

The expression can be rewritten has (2x^2 - 5x + 3) -1(-x^2 + 4x - 5)

After distributing the -1, the equation becomes:

  • (2x^2 - 5x + 3) + (x^2 - 4x + 5)

The like-terms are:

  • 2x^2 and x^2
  • -5x and -4x
  • 3 and 5

Combine the like-terms:

  • 2x^2 + x^2 = 3x^2
  • -5x - 4x = -9x
  • 3 + 5 = 8

Substitute the simplified like-terms into the expression, in descending order:

  • 3x^2 - 9x + 8
