Answer:

C) y=4x+2

Step-by-step explanation:

let's check all the options:

  • A) y=2(4)x=8x

if x = a

y(a)=8a

and now with x = a + 2

y(a+2)=8(a+2)=8a+16

the answer increased by 16. it is not the right option

  • B) y=2(8x)=16x

if x = a

y(a)=16a

and now with x = a + 2

y(a+2)=16(a+2)=16a+32

the answer increased by 32. it is not the right option

  • C) y=4x+2

if x = a

y=4a+2

and now with x = a + 2

y(a+2)=4(a+2)+2=4a+8+2=4a+10

this time, between 4a+2 and 4a+10 there is a difference of 8.

so for this function the statement is true.

Fazio chooses a jersey at random and then replaces it. He then selects a second jersey at random. What is the probability that f
Natalka [10]

Answer:

4% probability that fazio selects a striped jersey both times.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this problem:

For each jersey, there are 2+5+3 = 10 possible options, two of which are striped.

So twice 2/10

p = (\frac{2}{10})^{2} = \frac{4}{100}

4% probability that fazio selects a striped jersey both times.

Figure A
Amiraneli [1.4K]
<h2>Answer:</h2>

Figure B

<h2>Step-by-step explanation:</h2>

The Pythagorean Theorem is a^2 + b^2 = c^2, where c is the longest side of the triangle (the hypotenuse).

To find the side length of each square, you have to square root the area of each square. This means that Figure A has side lengths of 3, 6 and 8 units. Figure B has side lengths of 5, 12 and 13 units.

In Figure A, if the triangle is right-angled, the equation 3^2 + 6^2 = 8^2 must be correct. 9 + 36 = 45. 45 is not equal to 64, so the triangle is not right-angled.

In Figure B,  if the triangle is right-angled, the equation 5^2 + 12 ^2 = 13^2 must be correct. 25 + 144 = 169. 169 is 13 squared, so the triangle is right-angled.

Alternatively, as you are already given the square values for each side length, there is no need to square root and square again. You can just test if the two smaller areas equal the larger area, but the explanation above uses a more detailed example of the Pythagorean Theorem.
