O D. = 3.c – 2
Answers
Answer: y= D.3x-2
Step-by-step explanation:
Explanation:
To find the slope of two points, we need to use the formula m=rise/run or m=y2-y1/x2-x1
-2-7 -9
m = ——— = — = 3
-2-1 -3
Now we have to find “b” as in the equation “y=mx+b”
We already have our “m” which is the slope and that is equal to 3
In order to fine “b,” we have to set it up in point slope form which is the formula
“y-y1 = m(x-x1)”
You can choose to set this up with either one of the coordinates given
In this problem, the coordinates given are
(-2, -2) and (1, 7)
I’m going to use the coordinates (1, 7)
y-y1 = m(x-x1)
y-7 = 3(x-1)
The “7” is the y point
The “3” is the slope
The “1” is the x point
Now we simplify the equation:
y-7 = 3(x-1)
y-7 = 3x-3
+7 +7
—————
y = 3x + 4
Hope this helps and makes sense :)

What is the value of Fraction 1 over 2x3 + 3.4y when x = 2 and y = 5?
Answers
Answer:
1/33
Step-by-step explanation:
I'm assuming the 3 in 2x3 is an exponent (so hopefully that's what it is...)
When you plug in x and y, the denominator is
2(2)^3 + 3.4(5)
2x2^3= 2^4 which is 16 and 3.4x5= 17

Solve to find X. 3 ≥ -3x
Answers
Answer:
-1 ≤ x
Step-by-step explanation:
You just need to divide -3 on both sides.
-1 ≤ x
Note that since you are dividing by a negative number, the sign flips.
-1 ≤ x
Step-by-step explanation:
First start with the equation:
3 ≥ -3x
divide by -3 to get x positive and singular:
-1 ≥ x
and since we divided by a negative we need to flip the sign:
-1 ≤ x would be your answer

Answer:
4.93
Step-by-step explanation:
Given 3 numbers a, b and c, the formula for calculating their geometric mean is expressed as:
GM = ∛a*b*c
Given the numbers 4, 5 and 6
geometric mean = ∛4 * 5 * 6
geometric mean = ∛20*6
geometric mean = ∛120
geometric mean = 4.93
Hence the geometric mean is 4.93
