Answer:
a). y = 3/2x - 3/4 b).-2/3 c).y = -2/3x + 3
Step-by-step explanation:
a). 6x – 4y = 3
-4y = -6x + 3
y = 3/2x - 3/4
- The slope is 3/2.
b). The slope of a perpendicular line would be the opposite: -2/3
c). y = -2/3x + b
-1 = -2/3(6) + b
-1 = -4 + b
3 = b
y = -2/3x + 3
Answer:
B. 1/56
Explanation:
There are 8 different marbles. In the first draw, you have a one out of 8 chance of getting the red. In the second draw, there are 7 marbles remaining, so a one out of 7 chance of drawing a white marble. To find the total probability of drawing the red and then white marble, we multiply the probabilities if each draw.
(1/8)*(1/7)=1/56
The expression that represents the phrase "twice the difference of a number and 5" is 2(x - 5).
<h3>What is the expression that represents the phrase?</h3>
The difference of a number and 5 is given by:
x - 5.
As we don't know the number, hence we call it x.
Twice that is:
2(x - 5).
Hence the expression that represents the phrase "twice the difference of a number and 5" is 2(x - 5).

y=2x-0.5
Step-by-step explanation:
Given the expression of Δy in terms of Δx as;
Δy=4/2 Δx
Given y=2.5 and x =1.5 then substituting in the equation above will give;
y-2.5=2(x-1.5)
y-2.5=2x-3
y=2x-3+2.5
y=2x-0.5
