## Answers

**Answer 1**

**Answer:**

100

**Step-by-step explanation:**

y + 140 = 180 {Linear pair}

y = 180 - 140

y = 40

Given triangle is an isosceles triangle.

x + y + y = 180 {angle sum property of triangle}

x +2y = 180

x +2*40 = 180

x + 80 = 180

x = 180 - 80

x = 100

Show that the equation x^3 + 6x - 5 = 0 has a solution between x = 0 and x=1

### Answers

**Answer:**

**Step-by-step explanation:**

Solve the equation for 0 and 1:

x^3 + 6x -5

Replace x with 0:

0^3 + 6(0) -5 = -5

Replace x with 1:

1^3 + 6(1) -5 = 1+6 -5 = 2

Because the value of f(0) is negative and the value of f(1) is positive then there is at least one value of x between 0 and 1 that f(x) = 0

Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2, and the profit on every wrap is $3. Sal made a profit of $1,470 from lunch specials last month. The equation 2x + 3y = 1,470 represents Sal's profits last month, where x is the number of sandwich lunch specials sold and y is the number of wrap lunch specials sold.

Change the equation to slope-intercept form. Identify the slope and y-intercept of the equation. Be sure to show all your work.

Describe how you would graph this line using the slope-intercept method. Be sure to write using complete sentences.

Write the equation in function notation. Explain what the graph of the function represents. Be sure to use complete sentences.

Graph the function. On the graph, make sure to label the intercepts. You may graph your equation by hand on a piece of paper and scan your work or you may use graphing technology.

Suppose Sal's total profit on lunch specials for the next month is $1,593. The profit amounts are the same: $2 for each sandwich and $3 for each wrap. In a paragraph of at least three complete sentences, explain how the graphs of the functions for the two months are similar and how they are different.

when multiplying 32 and 12 how many partial products will there be

### Answers

**Answer:**

12

**Step-by-step explanation:**

32***12 **

**twelve is the amount of products there will be**

**Multiplication **is the process of multiplying. When **multiplying **32 and 12, the number of partial **products **will there be 4.

What is multiplication?

**Multiplication **is the process of **multiplying**, therefore, adding a number to itself for the **number **of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other **number**.

The **partial product **technique is multiplying each digit of a number in turn with each digit of another, with each **digit remaining **in its original **position**.

The **multiplication **of the two given term 32 and 12 can be done as,

32 × 12

= (30 + 2) × (10 + 2)

= (30×10) + (30×2) + (2×10) + (2×2) {This are the **partial **products}

Hence, when **multiplying **32 and 12, the number of partial **products **will there be 4.

Write an equation for a function that has a slope of 3 and that passes through the point (8, 14).

### Answers

**Answer:**

[tex]f(x)=3x-10[/tex]

**Step-by-step explanation:**

Recall point-slope form: Given a point [tex](x_{1}, y_{1})[/tex] and the slope [tex]m[/tex], the equation for the line is [tex]y-y_{1}=m(x-x_{1})[/tex].

We can plug in for our point and slope!

The equation for the line is [tex]y-14=3(x-8)[/tex].

Distributing the right side gives [tex]y-14=3x-24[/tex].

Adding [tex]14[/tex] to both sides gives [tex]y=3x-10[/tex].

So, the function is [tex]\boxed{f(x)=3x-10}[/tex] and we're done!

Which quadratic equation contains the three points (-4,12), (2,42), and (3,40)

### Answers

The quadratic equation that contains the three points is **y = -x² + 3x + 40**

A quadratic equation is in the form:

**y = ax² + bx + c**

At point (-4, 12):

12 = a(-4)² + b(-4) + c

**16a - 4b + c = 12** (1)

At point (2, 42):

42 = a(2)² + b(2) + c

**4a + 2b + c = 2** (2)

At point (3, 40):

40 = a(3)² + b(3) + c

**9a + 3b + c = 40** (3)

Solving equation 1, 2, and 3 gives:

a = -1, b =3, c = 40

**y = -x² + 3x + 40**

Hence the quadratic equation is **y = -x² + 3x + 40**

Rewrite the quadratic function from standard form to vertex form.

f(x)x^2+6x-5

### Answers

**Answer:**

[tex]y = {(x + 3)}^{2} - 14[/tex]

**Step-by-step explanation:**

The original equation

[tex] f(x) = {x }^{2} + 6x - 5[/tex]

vertex form

[tex]y = a {(x - h)}^{2} + k \\ where \: (h. \: k) \: is \: the \: vertex[/tex]

solve for the x coordinate of the vertex, h

[tex]x = h = - \frac{b}{2a} = - \frac{6}{2(1)} = - \frac{6}{2} = - 3 \\ x = h = - 3[/tex]

substitute -3 back into the original equation to solve for y

[tex]y = { (- 3)}^{2} + 6( - 3) - 5 \\ y = 9 - 18 - 5 \\ y = 4 - 18 \\ y = k = - 14 [/tex]

substitute h and k values into the vertex form

a = 1 So we can omit it

[tex]y = {(x - ( - 3)}^{2} - 14 \\ y = {(x + 3)}^{2} - 14[/tex]

Factorize 3x² + 7xy - 6y².

Evaluate the expression in (a) above if x = 4 and y = 3.
