Answer:
B. y = [tex]\frac{2}{15} X + 2[/tex]
Step-by-step explanation:
I. Given x = 15 and y = 4
4 = [tex]\frac{2}{15}(15) + 2[/tex]
4 = 2+2
4 = 4 true
II. Give x = 0 and y = 2
2 = [tex]\frac{2}{15}(0) + 2[/tex]
2 = 0 + 2
2 = 2 true
III. Given x = -15 and y = 0
0 = [tex]\frac{2}{15}(-15) + 2[/tex]
0 = -2 + 2
0 = 0 true
Good luck.
What is the arc length of arc cd in the circle below. The circle has a radius of 6ft and an angle measure of 30
9514 1404 393
Answer:
π ft ≈ 3.14 ft
Step-by-step explanation:
The angle is 1/12 of the number of degrees in a circle, so the arc length will be 1/12 of the circumference of the circle.
C = 2πr
1/12C = 2/12π(6 ft) = π ft ≈ 3.14 ft
The arc length is about 3.14 feet.

If no sides of a triangle have the same length, the triangle is called scalene
(pronounced SKAY-leen). And, as you might remember, if the triangle has at
least two sides that are the same length, the triangle is called isosceles. Use the
markings or description in each diagram below to decide if AABC is isosceles or
scalene. Assume the diagrams are not drawn to scale.
Answer:
a. isosceles
b. isosceles
c. scalene

a. (2x+5)(2x−5)
b. (2x−5)(2x−5)
c. (4x+5)(x−5)
d. (3x+20)(x+5)
Answer:
The correct choice is option a. (2x+5)(2x−5)
Answer:
Option a. (2x+5)(2x-5)
Step-by-step explanation:
4x2 - 25
Furthermore, this is the difference of squares formula we will use to factor 4x^2-25:
a2 - b2 = (a + b) • (a − b)
As you can see, our problem does not look like the left side of the formula, so first we have to convert our problem to match the left side like so:
4x2 - 25 = (2x)2 - 52
Now that it matches, we can simply plug in 2x for a and 5 for b into the formula to get the factors of 4x^2-25:
(2x + 5) • (2x − 5)

Rewrite 14 / 25 and 11 / 20 so that they have a common denominator
The fraction equivalent of the given fractions with the same denominator is written as [tex]\frac{56}{100} \ and \ \frac{55}{100}[/tex]
The given parameters include:
[tex]\frac{14}{25} \ and \ \frac{11}{20}[/tex]
To rewrite the given fractions to have the same denominator, we must find the LCM of the denominators;
The prime factorization of 25 = 5²
The prime factorization of 20 = 5 x 2²
The LCM of the two numbers = 5² x 2² = 25 x 4 = 100
The fractions can rewritten as follows;
[tex]\frac{14}{25} \ = \frac{14}{25} \times \frac{4}{4} = \frac{14 \times 4}{25 \times 4} = \frac{56}{100} \\\\\frac{11}{20} \ = \frac{11}{20} \times \frac{5}{5} = \frac{11 \times 5}{20 \times 5} = \frac{55}{100}[/tex]
Thus, the fraction equivalent of the given fractions with the same denominator is written as [tex]\frac{56}{100} \ and \ \frac{55}{100}[/tex]

if (a+b)=3 and ab=2, find the value of a2+b2
Answer: so a^2 + b^2 = 5
Step-by-step explanation:
(a+b) = 3
ab = 2
so
(a+b)^2 = 3^2
a^2 + 2ab + b^2 = 9
or, a^2 + 2*2 + b^2 = 9
or, a^2 + 4 + b^2 = 9
or, a^2 +b^2 = 9-4 = 5

A rectangular picture frame has length three inches longer than twice it’s width. The perimeter is 36 inches. Find the width of the frame.
a.) 5in
b.) 7in
c.) 10in
d.) 11in
Answer:
A. 5 in
Step-by-step explanation:
Let w represent the width of the frame.
If the length is 3 inches longer than twice the width, it can be represented by 2w + 3.
Use the perimeter formula, p = 2l + 2w. Plug in the perimeter and 2w + 3 as l, and solve for w:
p = 2l + 2w
36 = 2(2w + 3) + 2w
36 = 4w + 6 + 2w
36 = 6w + 6
30 = 6w
5 = w
So, the width of the frame is 5 inches.
The correct answer is A. 5 in
