Answer:
25x² - 16
Step-by-step explanation:
Given
(5x + 4)(5x - 4)
Each term in the second factor is multiplied by each term in the first factor, that is
5x(5x - 4) + 4(5x - 4) ← distribute parenthesis
= 25x² - 20x + 20x - 16 ← collect like terms
= 25x² - 16

tell whether the slope is positive or negative. then find the slope.
Answer:
slope is negative
m=-1
Step-by-step explanation:
the slope of a line is positive if it passes through Quadrants III and I. The slope is negative if it passes through II and IV.
yes, this line passes through Quadrant I alongside II and IV, but it doesn't pass through Quadrant III (it has to pass through Quadrant III to be positive)
that means that the slope of this line must be negative
We can calculate the slope (m) with this formula:
(y2-y1)/(x2-x1)
we can pick two points- for example, (1,3) and (2,2)
label the points:
x1=1
y1=3
x2=2
y2=2
now substitute into the equation
m=(2-3)/(2-1)
m=-1/1
m=-1
the slope is -1
Hope this helps! :)

Answer:
Angle 2 = Angle 4 = 76
Step-by-step explanation:
Here, we want to get the measures of angle 2 and angle 4
From what we have in the diagram, angle 2 and angle 5 are supplementary (meaning they add up to 180)
The reason for this is because both angles are same side interior angles
Thus,
angle 2 + angle 5 = 180
angle 2 = 180 - angle 5
angle 2 = 180 -104
angle 2 = 76
Furthermore, we can see that angle 2 equals angle 4 as they are vertically opposite angles
Thus, angle 2 = angle 4 = 76

Answer:
x = -3.73 or -0.27
Step-by-step explanation:
From the question,
x²+ 4x+1 = 0
This is a quadratic equation, and it can be solved using any of the 3 methods.
Using completing the square method,
x²+4x = -1
Add half the coeffiecient of x, square it and add it to both side of the equation.
The coefficient of x is 4,
half the cofficient is 2
Add 2² to both side of the equation
x²+4x+2² = -1+2²
(x+2)² = 3
x+2 = ±√3
x+2 = ±1.73
Either,
x+2 = -1.73
x = -1.73-2
x = -3.73
or
x+2 = +1.73
x = =1.73-2
x = -0.27
Use the Distributive property to choose the equivalent expression for 9(n- 2)
Answer: 9n-18
Step-by-step explanation:
1. We distribute the 9 to the n and -2
2. 9n-2(9)
3.9n-18 is our answer.
Answer: 9n-18 would be equivalent to to 9(n-2)
Step-by-step explanation: First multiply 9 times n. Then multiply 9 and 2 and you get -18.

what is the slope intercept of this equation?
After Selling 15 Lemonades, Jessica made 5 dollars. After selling 42 lemonades, she made 18.50
Answer:
y = 1/2x - 2.5
Step-by-step explanation:
(15, 5) and (42, 18.5)
Slope:
m=(y2-y1)/(x2-x1)
m=(18.5 - 5)/(42 - 15)
m = (13.5)/27
m = 1/2
y - y1 = m(x - x1)
y - 5 = 1/2(x - 15)
y - 5 = 1/2x - 7.5
y = 1/2x - 2.5
Answer:
2 or 1/2
Step-by-step explanation:
change in y over change in x
you didnt define what what x and what was y so ill provide both answers and you can figure which is correct
42-15/18.50-5 =27/13.5 =2
18.50-5/42-15 =13.5/27 =1/2
