**Answer 1**

**Answer:**

A and D

**Step-by-step explanation:**

They're the same shape because all of the angles are congruent

They're similar because the lengths of the sides are proportional

**Answer 2**

The two triangles ΔXYZ and ΔUVW are having same **shape** and they both are **similar** triangles, Option A and D are correct.

What is Triangle?

A triangle is a three-sided polygon that consists of three **edges** and three vertices.

Two triangles are said to be similar if their corresponding **angles** are **congruent** and the corresponding sides are in proportion .

The given two triangles are ΔXYZ and ΔUVW.

As we observe the two **triangles** they are in the same shape.

The angles are congruent.

The sides of the two triangles are **proportional**.

So the two triangles are similar.

ΔXYZ and ΔUVW are the **similar** triangles.

Hence, the two triangles ΔXYZ and ΔUVW are having same **shape** and they both are **similar** triangles, Option A and D are correct.

The ordered pair (x,y)=(8, 6) is the solution of the following system of linear equations

x = 1/10y + a

y = 1/10x + b

whats a +b?

### Answers

**Answer:**

63/5

**Step-by-step explanation:**

when x = 8 and y = 6

the two equations become

8 = 1/10 * 6 + a & 6 = 1/10 * 8 + b

which simplify to

8 = 3/5 + a & 6 = 4/5 + b

so a = 8 - 3/5 = 37/5 & b = 6 - 4/5 = 26/5

a + b = 37/5 + 26/5 = 63/5

A piecewise-defined function has different rules for different parts, or pieces, of its

domain. In order to evaluate a piecewise defined function for a given value of x

find the interval, or piece, that y belongs to. Find the corresponding definition at

the function for that interval

### Answers

Applying the **piecewise function**, we have that:

**a) **[tex]f(-5) = 3[/tex]

**b) **[tex]f(-4) = 3[/tex]

**c) **[tex]f(-3) = 3[/tex]

**d) **[tex]f(-2) = -4[/tex]

**e) **[tex]f(-1) = -3[/tex]

**f) **[tex]f(0) = -2[/tex]

--------------------------

The **function **is:

[tex]f(x) = 3, -5 \leq x < -2[/tex]

[tex]f(x) = x - 2, -2 \leq x \leq 0[/tex]

For **items a, b and c**, the input x is values between -5 and -2, thus, the **definition **is:

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

Then

[tex]f(-5) = 3[/tex]

[tex]f(-4) = 3[/tex]

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

For items **d, e and f,** values of x between -2 and 0, thus, the **definition **is:

[tex]f(x) = x - 2[/tex]

Then

[tex]f(-2) = -2 - 2 = -4[/tex]

[tex]f(-1) = -1 - 2 = -3[/tex]

[tex]f(0) = 0 - 2 = -2[/tex]

Andy is considering taking a loan to remodel his kitchen. He is offered a loan by his bank for five years and an annual interest of 6.5% with monthly payments. To the nearest $100, what is the maximum amount of money he can borrow if he can only afford to pay back $200 per month?

### Answers

Using **compound interest,** it is found that the **maximum amount** of money he can borrow is of **$8,700.**

------------------------

The **compound interest** formula is given by:

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

**A(t) **is the amount of money after t years.**P** is the principal(the initial sum of money). **r** is the interest rate(as a decimal). **n **is the number of times that interest is compounded per year.**t **is the time in years.

**Maximum **monthly payments of $200 per month per five years, thus:

[tex]A(t) = 5 \times 200 \times 12 = 12000[/tex]

**Interest rate of 6.5%**, thus [tex]r = 0.065[/tex].**Monthly **payments, thus [tex]n = 12[/tex].**Five years**, thus [tex]t = 5[/tex].The amount he can borrow is the **principal**.

[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]

[tex]12000 = P(1 + \frac{0.065}{12})^{60}[/tex]

[tex]1.38282P = 12000[/tex]

[tex]P = \frac{12000}{1.38282}[/tex]

[tex]P = 8678[/tex]

To the nearest 100, $8,700.

The **maximum amount** of money he can borrow is of **$8,700.**

Find the x-intercept and y-intercept of the graph of the equation 5x + 3y = 15.

### Answers

X intercept: (3,0)

Y intercept: (0,5)

**Answer:**

x-intercept: (3,0)

y-intercept: (0,5)

---------------------- explanation ---------------------------

so to find x-inter you need to replace y for 0 and then solve X.

example: 5x +3(0) = 15

and do the same to fine y-inter, replace x with 0 then solve for y.

example: 5(0) +3y = 15

Which statement is true about the graph function f? f(x)=log2x

### Answers

The correct statement about the **graph function** f(x) = log₂x is; The graph has an asymptote of x = 0 and is negative over the interval (0, 1).

How to Interpret Function Graphs?

We are given the **function;**

f(x) = log₂x

Now, at f(0), we have;

f(x) = log₂(0)

f(x) = log 0/log 2

f(x) = -∞/0.3010

Thus, since the value is **infinity**, then we can say that a straight line constantly approaches the curve but does not meet at any **infinite distance** and as such there is an **asymptote** at x = 0 and it is negative over the interval (0, 1).

The missing options are;

A. The graph has an asymptote of x = 0 and is positive over the interval (0, 1).

B. The graph has an asymptote of x = 0 and is negative over the interval (0, 1).

C. The graph has an asymptote of y = 0 and is decreasing as x approaches positive infinity.

D. The graph has an asymptote of y = 0 and is increasing as x approaches positive infinity.
