Question

Combining Like Terms 1. 10Z-4B+3Z+16B-Z
2. -5M-3P+5P+12P
3. 12P-4M+8P-3M-2P
4. 10B-5M-4B+8B-4M
5. 4Z+3Z-6Z+B
6. 7B+3X-8B+6X
(By the way Those letters without a number by it, is 1. So EX: 4Z+5+Z is 5Z+5 ) โ

Solution 1

**Step-by-step explanation:**

1. 10Zโ4B+3Z+16BโZ = 10Z+3ZโZ+16Bโ4B

= 12Z+12B = 12(Z+B)

2. โ5Mโ3P+5P+12P = 12P+5Pโ3Pโ5M = 14Pโ5M

3. 12Pโ4M+8Pโ3Mโ2P = 12P+8Pโ2Pโ4Mโ3M

= 18Pโ7M

4. 10Bโ5Mโ4B+8Bโ4M = 10B+8Bโ4Bโ5Mโ4M

= 14Bโ9M

5. 4Z+3Zโ6Z+B = Z+B

6. 7B+3Xโ8B+6X = 6X+3X+7Bโ8B = 9XโB

Question

HELP PLEASE! Write a quadratic function that passes through the point (-1,9), has an axis of symmetry of x=-3 and a minimum value of 7.

Solution 1

**Answer:**

**Step-by-step explanation:**

Vertex Form of a quadratic equation;

Vertex of the parabolas (h, k)

The vertex of the parabola is either the minimum or maximum of the parabola. The axis of symmetry goes through the x-coordinate of the vertex, hence h = -3. The minimum of the parabola is the y-coordinate of the vertex, so k= 7. Now substitute it into the formula;

Now substitute in the given point; ( -1, 9) and solve for a;

Hence the equation in vertex form is;

In standard form it is;

Question

A family went to a restaurant for dinner. The subtotal for the meal including tax is $65.90. The family decided to leave a 20% tip. How much did the family pay total including tip?

Solution 1

**Answer:**

$79.08

**Step-by-step explanation:**

Find 20% of 65.90. 20% as a decimal is 0.20. Multiply 0.2 and 65.90.

65.90 x 0.20 = 13.18

Add 13.18 to the original price.

13.18 + 65.90 = 79.08

Question

50 โ 5(4.3 โ 1.3) รท 0.5

Solution 1

**Answer:**

(0.5, 1.3)(0.5, 1.3)

**Step-by-step explanation:**

Given equations are:

As we can see that the given equations are linear equations which are graphed as straight lines on graph. The solution of two equations is the point of their intersection on the graph.

We can plot the graph of both equations using any online or desktop graphing tool.

We have used "Desmos" online graphing calculator to plot the graph of two lines (Picture Attached)

We can see from the graph that the lines intersect at: (0.517, 1.267)

Rounding off both coordinates of point of intersection to nearest tenth we get

(0.5, 1.3)

Hence,

(0.5, 1.3) is the correct answer
