9x^2 - 16 = (px+t)(px-t) both p and t are constants. Which of the following could be the value of p

Answers

Answer 1

Answer:

Answer:

p = 3

Step-by-step explanation:

9x² - 16 ← is a difference of squares and factors in general as

a² - b² = (a + b)(a - b)

Thus

9x² - 16

= (3x)² - 4²

= (3x + 4)(3x - 4)

Compare with (px + t)(px - t)

then p = 3

Whats 1/5 divided by 5

Answers

1/5 ÷ 5
when a fraction is being divided by a number you multiply the first number by the reciprocal of the second number. A reciprocal is basically a number that can be multiplied by the first number to make 1
So in this case the reciprocal of 5 is 1/5
now just multiply and get 1/25
So the answer is 1/25

First, we have to make sure both numbers are fractions.
The first number is already a fraction; make the second whole number into a fraction.

$5$ as a fraction is $(5)/(1)$ .

Now follow these steps:
Rewrite equation.
Switch division sign to multiplication.
Find reciprocal of the second fraction, which means to flip the fraction around.
Cross multiply.
Simplify if needed.

Now let's put that into this equation.

$(1)/(5)/ (5)/(1)\n \n(1)/(5) * (5)/(1) \n \n (1)/(5) * \frac {1}{5} \n \n 1*1=1\n4*5=25 \n \n (1)/(25)$

Given the domain {-5, 0, 5}, what is the range for the relation 2x+y=1

Answers

The domain x ∈ {-5; 0; 5}
the relation: 2x + y + =1 → y = 1 - 2x

Put the values of x from domain to the equation of the relation:
for x = -5 → y = 1 - 2(-5) = 1 + 10 = 11for x = 0 → y = 1 - 2(0) = 1 - 0 = 1for x = 5 → y = 1 - 2(5) = 1 - 10 = -9
Answer: {-9; 1; 11}

Ray UW is the angle bisector of VUT. If mVUW = (4x + 6)° and mWUT = (6x – 10)°, what is the measure of WUT?
32°
38°
48°
76°

Answers

In the question "Ray UW is the angle bisector of VUT. If mVUW = (4x + 6)° and mWUT = (6x – 10)°, what is the measure of WUT?" It was given that UW is the angle bisector of VUT, which means that mVUW = mWUT. i.e. 4x + 6 = 6x - 10 6x - 4x = 6 + 10 2x = 16 x = 8 Therefore, the measure of WUT = 6x - 10 = 6(8) - 10 = 48 - 10 = 38
