The answer would be x<-4, so the answer would be “A number line with an open circle on -4 shaded to the left.
Explanation: -2x/-2 > 8/-2 = x < -4
It couldn’t be anything else but C line reflection i’m assuming
Answer:
3
Step-by-step explanation:
Get rid of fractions:
Multiply the whole equation, i.e. all terms both sides of the equals sign, by the denominator or the lowest common multiple of all denominators if there are multiple fractions in the equation;
In this case, only one term is a fraction and therefore has a denominator (i.e. 7), so it is this number we multiply the equation by to get:
7(y) = 7(-³/₇.x) + 7(3)
7y = -3x + 21
3x + 7y = 21
Answer:
-1
Step-by-step explanation:
The given equation has a y-intercept of 8, so goes through the point (0, 8).
If the line also goes through the point (2, 6) it has a slope of ...
(y2 -y1)/(x2 -x1) = (6 -8)/(2 -0) = -2/2 = -1
The slope of the line is -1.
_____
The value of A is -2.
Let red marbles = X.
The probability is 1 out of 5, written as 1/5
1/5 in terms of red marbles is equal to the number of red marbles divided by 5x, where 5x is the total number of marbles.
1/5 = x/5x
Now you have 5x total marbles, x red and 4x blue.
Add 5 more red and the new probability is:
(x+5)/(5x+5) = 1/3
Simplify:
3x+15 = 5x+5
Now solve for x:
Subtract 3x from both sides:
15 = 2x +5
Subtract 5 from each side:
2x = 10
Divide both sides by 2:
x = 10/2
X = 5
There were originally 5 red marbles.
