Answer:
9 and -4
Step-by-step explanation:
change the word form to math form so now
x² - 36 = 5x <u>This look like a factoring problem, so we put it equal to 0</u>
x² - 5x - 36 = 0 <u>Now factor</u>
(x - 9) (x + 4) <u>We have to find 2 numbers that give -36 when we multiply and -5x when we add</u>
x - 9 = 0
x = 9
x + 4 = 0
x = -4
you can check by plugin the x value to actual equation.
1. positive integer
2. opposites
3. absolute value
4. rational number
Answer:
y = -4x-21
Step-by-step explanation:
Hi there!
We want to write an equation of the line that passes through (-4, -5) and is parallel to y=-4x-1.
Parallel lines have the same slopes. So let's find the slope of y=-4x-1.
The line is written in the form y=mx+b, where m is the slope and b is the y intercept.
As -4 is in the place of where m should be, -4 is the slope of y=-4x-1.
It's also the slope of the line parallel to that line.
Right now, what we know about the line parallel to y=-4x-1 is that the slope of it is 4 and it passes through the point (-4, -5).
We can substitute those values into the formula for point-slope form, which is , where m is the slope and is a point.
We can label the values of everything to help us avoid confusion.
m=-4
Now substitute those values into the formula. Note: the formula contains SUBTRACTION, and we have NEGATIVE numbers. Hence,
Now simplify.
On the right side, do the distributive property.
y+5=-4x-16
Subtract 5 from both sides.
<u>y=-4x-21</u>
Hope this helps!
Simply
Yes it shows the additional charge
Solve for d by simplifying both sides of the equation then isolating the variable.
d = -70.
