What is 9-4(2p-1)=45?

Answers

Answer 1

Answer: 9 - 4(2p - 1) =45
5(2p - 1) = 45
10p - 5 = 45
10p = 45 + 5
10p = 50
p = 50/10
p =5 (ans)

Answer 2

Answer: 9-4(2p-1)=45
5(10p-5)=45
10p-5=45
10(5)-5=45
50-5=45
45=45

Answer:

No real

solution

Step-by-step explanation:

Firstly, let us check if we would be having a real solution

We start by rewriting the equation

We have this as;

8x^2 -25x + 24 = 0

We proceed to get the discriminant

Mathematically, we have this as;

D = b^2 - 4ac

b is the coefficient of x which is -25

a is the coefficient of x^2 which is 8

c is the last number which is 24

So we have;

D = (-25)^2 - 4(8)(24)

D = 625 - 768 = -143

Since the value of the discriminant is negative, there cannot be real roots

What we have as solution are complex roots

The function f(x) = −x^2 − 5x + 50 shows the relationship between the vertical distance of a diver from a pool's surface f(x), in feet, and the horizontal distance x, in feet, of a diver from the diving board. What is a zero of f(x), and what does it represent?A. x = 5; the diver jumps in the pool at 5 feet per second
B. x = 10; the diver jumps in the pool at 10 feet per second
C. x = 10; the diver hits the water 10 feet horizontally from the board
D. x = 5; the diver hits the water 5 feet away horizontally from the board

Answers

We will solve the equation to find a zero of f(x): $-x^(2)-5x+50=0$
The formula is: $x_(12) = \frac{-b\pm \sqrt{b^(2)-4ac } }{2a}$ where:
a=-1, b=-5, c =50 $x_(12) = (5\pm √(25+200) )/(-2)= (5\pm √(225) )/(-2)= (-10)/(-2)=5$ This is the only solution because the other is: $(5+10)/(-2)= (15)/(-2)=-7.5$ which is not possible.
Answer: D) The diver hits the water 5 feet away horizontally from the board.

P^2 _ p^2 = 7 and p _ q = 2
find the value of p+q

Answers

The value of p+q is 7/2

Difference of two squares

Given the difference of two square

p^2 - q^2 = 7

Using the formula for finding the p+q

(p+q)(p-q) = 7

Given that p-q = 2

Substitute into the formula

2(p+q) = 7

p+q = 7/2

Hence the value of p+q is 7/2

Hey There!

Let's solve...

${p}^(2) - {q}^(2) = ( p - q)(p + q) \n \n = 2(p + q) \n \n = (7)/(p + q) \n \n = (7)/(2)$

Write the slope-intercept form of the equation of the line through the given point with the given slope. through: (-5, -1); slope = negative 3 over 5

Answers

Answer:

The slope-intercept form of the equation of the line is $y = -(3)/(5) \cdot x -4$ .

Step-by-step explanation:

We know that the slope-intercept form of the equation of the line is represented by:

$y = m\cdot x + b$

Where:

$x$ - Independent variable, dimensionless.

$y$ - Dependent variable, dimensionless.

$m$ - Slope, dimensionless.

$b$ - y-Intercept, dimensionless.

From statement we find that $m =-(3)/(5)$ . If $x = -5$ and $y = -1$ , the value of the y-intercept is:

$-1 =-(3)/(5)\cdot (-5)+b$

$-1 = 3 + b$

$b = -4$

The slope-intercept form of the equation of the line is $y = -(3)/(5) \cdot x -4$ .

(B) Number of football games played and the position of a football player.
(C) High temperature of the day and number of zoo visitors that day.
(D) Type of beverage ordered and time of day it was ordered.
(E) Brand of cell phone and number of cell phones sold.

Answers

The relationship which could be described using correlation, r is; Choice C; High temperature of the day and number of zoo visitors that day.

What is correlation

Correlation is a statistical measure that expresses the extent to which two variables are linearly related (meaning they change together at a constant rate). It's a common tool for describing simple relationships without making a statement about cause and effect.
