Answer:

x = {-0.44, 1.69}

Step-by-step explanation:

Multiply by the denominator to eliminate the fraction.

3 = x(4x -5)

4x^2 -5x -3 = 0 . . . . . subtract 3 and put in standard form

Using the quadratic formula with a=4, b=-5, c=-3, we have the solutions as ...

[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}=\dfrac{-(-5)\pm\sqrt{(-5)^2-4(4)(-3)}}{2(4)}\\\\x=\dfrac{5\pm\sqrt{73}}{8}\approx \{-0.443, 1.693\}[/tex]

Solutions rounded to hundredths are ...

x = -0.44

x = 1.69

_____

A graphing calculator can show the x-intercepts easily, so it works well to write the equation in the form

f(x) = 0

3/(4x -5) -x = 0

the answer is g(-9)=1 and teachers have one job and they can barely do it right

At the coordinate of -9, the value of the function g(-9) will be 1.

What is coordinate geometry?

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

Given that in the graph the function is varies with the value of the coordinates, at the value of -9 the solution for the function g(-9) will be equal to 1

g(-9) = 1

Hence, the value of the function will be 1.

Answer:

probs too late, but i think the answer is x=12

Step-by-step explanation:

the angles should add up to equal 180

180-36=144

144=8x+4x

144=12x

now divide by both sides to isolate x

12=x

u can check by plugging in ofc, 36+(8x12)+(4x12)=36+96+48=180

Answers

Answer:

x= -2

Step-by-step explanation:

Simplifying 5x + 45 = 35 Reorder the terms: 45 + 5x = 35 Solving 45 + 5x = 35 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-45' to each side of the equation. 45 + -45 + 5x = 35 + -45 Combine like terms: 45 + -45 = 0 0 + 5x = 35 + -45 5x = 35 + -45 Combine like terms: 35 + -45 = -10 5x = -10 Divide each side by '5'. x = -2 Simplifying x = -2

Answer:

x = 48

Step-by-step explanation:

first you would add them together and set it equal to 180( because a straight line is 180 degrees): 3x - 12 + x = 180

Then you add like terms( the x's): 4x - 12 = 180

now add 12 to both sides: 4x = 192

now divide by 4 on both sides x = 48

Quiana has 7 times more text messages from Yolanda than from Pierre. Quiana has 42 text messages from Yolanda. Which equation can be used to find how many text messages Quiana has from Pierre, p?

Answers

Answer:
Quiana has 8 text messages from Pierre.
Step-by-step explanation:
This question can be solved using a rule of three.
Quiana has 7 times more text messages from Yolanda than from Pierre.
This means that for each message that she receives from Pierre, she receives 7 from Yolanda.
She received 56 from Yolanda.
So
7 messages from Yolanda - 1 messages from Pierre
56 messages from Yolanda - x messages from Pierre

Quiana has 8 text messages from Pierre
