Answer:
[tex]\bold{a_n=4n-9}[/tex]
Step-by-step explanation:
-1-(-5) = 4 and 3-(-1) = 4 and 7-3 = 3
so: d=4

Answer:
1/5log2(x)+4/5log2(y)-4/5
Step-by-step explanation:
=log2{(xy^4/16)}^1/5
=1/5×log2(xy^4/16)
=1/5×{log2(xy^4)-log2(16)}
=1/5×{log2(x)+log2(y^4)-log2(2^4)}
=1/5×{log2(x)+log2(y^4)-4)} ( as loga(a^x)=x)
=1/5×log2(x)+1/5log2(y^4)-4×1/5 (distribute 1/5 through the parentheses)
=1/5×log2(x)+1/5×4log2(y)-4/5
=1/5log2(x)+4/5log2(y)-4/5

Answer:
3x +2y = -38
Step-by-step explanation:
When a point and the slope are given for a line, the point-slope form of the equation is useful.
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
y -(-4) = -3/2(x -(-10))
y + 4 = -3/2x -15
Multiplying by 2 gives ...
2y +8 = -3x -30
Adding 3x-8, we get ...
3x +2y = -38
Answer:
3x + 2y = -38
Just plug in the x and y values to get the answer!
We already know that when x is -10 y = -4 so all we have to do is substitute them.
y = mx + b
-4 = -3/2(-10) + b
-4 = 30/2 + b
-4 = 15 + b
-19 = b

R12 16 20 24 O The height of the water increases 2 inches per minute. The height of the water decreases 2 inches per minute. The height of the water was 2 inches before any water was added. O The height of the water will be 2 inches when the pool is filled.
Answers
Answer:
Step-by-step explanation:
Answer:
A) The height of the water increases 2 inches per minute.
Step-by-step explanation:
Slope is the rate of change of height
m = (16 - 12)/(4 - 2) = 4/2 = 2
2 inch per min
Positive slope implies increase

Answer:
slope = 2
Step-by-step explanation:
-8 - -6 / -9 - -8 = 2
Answer:
[tex]\frac{2}{1}[/tex] which is just 2
Step-by-step explanation:
slope = [tex]\frac{y2 - y1}{x2 - x1}[/tex]
So plug the numbers in, now it should look like [tex]\frac{-6 - (-8)}{-8 - (-9)}[/tex]
-6 - (-8) = 2
-8 - (-9) = 1
So the slope is [tex]\frac{2}{1}[/tex]

Make a sketch of a linear relationship with slope 3 that is not a proportional relationship show how you know hay slope is 3 write an equation for the line
Answers
Answer:
A proportional relationship is something like:
y = k*x
Where k is the constant of proportionality
And a linear relationship is something like:
y = a*x + b
Is easy to see that if:
a = k, and b = 0, this would be a proportional relationship.
Then if we want to have a slope equal to 3, but this must not be a proportional relationship, we must only have b different than 0.
This could be something like:
y = 3*x + 1
The graph of this is:
A linear non - proportional relationship could be written with as a slope - intercept with a non - zero intercept value. One such relationship with a slope of 3 can be expressed thus :
y = 3x + 5Here, the linear relationship, has a slope value of 3 and an intercept value of 5. The function cannot be proportional due to the presence of a non-zero constant
Hence, Using a graphing calculator, the sketch of the linear relationship is attached.
