plss i need help for this question real fast ?(10-(-9)*-1) plss real quick!!!!
Answers
Answer:
1
Step-by-step explanation:
(10-(-9)*-1)
Remember that 2 negative equal a positive. So -(-9) is positive.
(10+9*-1)
Then, PEMDAS is how you should finish this.
So, 9*-1 is -9
Then, 10-9 is 1

Write an equation in slope-intercept form of the line shown. y 4 (0, 3) (4, 2) 2 2 4 x
Answers
Answer:
The slope intercept form of (0,3) and (4,2) is y= -1/4x+3
Step-by-step explanation:
The distance from our y values from 3 to 2 is -1.
The distance from our x values is 4.
We can put these values as our slope and we know that the Y values are always rise and the x values are always run
Therefore we get y= -1/4x+3 (side note: The 3 is our y intercept, this means that the x value of the three is always 0. For example, in (0,6) the y intercept would be 6.
Hope this helps! :)
Identify the reference angle Ф for each given angle, Ф.
When ∅=300°, Ф=
Answers
=====================================================
Explanation:
The given angle is ∅ = 300. This x value is between 270 and 360, so we're in quadrant IV (the southeast quadrant)
The rule to get the reference angle y for this quadrant is
Ф = 360-∅
This tells us the angle made with the positive x axis
Ф = 360-∅
Ф = 360-300
Ф = 60
A 60 degree angle forms with the positive x axis as shown in the diagram below.
A triangular garden has two rock walls meeting at a right angle. The length of one of the walls is 20 feet. Use the image to find d, the length of the other wall.
Answers
Step-by-step explanation:
Here you go, I hope this is helpfull
The length of the other side of the wall is √500 ft
Pythagoras theorem
To get the length of 'd', we will use the pythagoras theorem as shown below:
Given the following
Hypotenuse = 30ftAdjacent = 20ftAccording to the theorem;
[tex]h^2=a^2+d^2\\30^2 = 20^2 + d^2\\900 = 400 + d^2\\d^2 = 900 - 400\\d = \sqrt{500} ft[/tex]
Hence the length of the other side of the wall is √500 ft

A line crosses through the points (0,2) and (-10, -16) Which of the following is the slope of the line?
A
[tex] \binom{9}{5} [/tex]
b
[tex] - \binom{9}{5} [/tex]
c
[tex] \binom{1} {3} [/tex]
d
[tex] \binom{5}{9} [/tex]
Answers
Answer:
9/5
Step-by-step explanation:
The slope between the two points can be found by ...
m = (y2 -y1)/(x2 -x1)
m = (-16-2)/(-10-0) = -18/-10
m = 9/5
The slope of the line is 9/5. Perhaps this is a match to choice A.
Answer: 9/5
m = (y2 -y1)/(x2 -x1)
m = (-16-2)/(-10-0) = -18/-10
m = 9/5

Answers
Answer:
no solution
Step-by-step explanation:
Given
[tex]\frac{1}{3}[/tex] (21 - 3a) = 6 - a ( multiply through by 3 to clear the fraction )
21 - 3a = 18 - 3a ( subtract 21 from both sides )
- 3a = - 3 - 3a ( add 3a to both sides )
0 = - 3 ← not possible
This indicates the equation has no solution
