Since we need to find the point at which the 2 lines intersect at the x-axis, we need to find where the 2nd line intersects the x axis, by plugging in y=0.
x-2(0)=4
x=4
Therefore, at (4,0).
Now we plug in (4,0) at the first equation.
4b+3(0)=10
4b=10
b=5/2
Therefore, at b=5/2
Mean: The average or the center of the value. To find this, you add up all the numbers and divide by how many numbers there are.
Example: 3, 4, 5
3+4+5 = 12.
There are 3 numbers.
12/3 = 4. The mean is 4
Median: Median means the middle value. You place the numbers in order and locate the middle value.
Example: 5, 4, 3 -> 3,/ 4,/ 5. Middle number 4.
Mode: Place the numbers in order then count how much each number appears. The number that appears the most repeatedly would be the mode.
Example: 3, 4, 4, 4, 5, 5.
The mode would be 4.
Range: Locate the highest and the lowest values of the given set and subtract the smallest to the largest.

Answer:
x = 7
Step-by-step explanation:
The sum of interior angles is equal to 360°
9x - 4 + 8x + 2 + 13x + 30 + 19x - 11 = 360° add like terms
49x + 17 = 360 subtract 17 from both sides
49x = 343 divide both sides by 49
x = 7
replace x with the value we found to calculate each angle.
Answer:
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(3-(-1))/(-2-4)
m=(3+1)/-6
m=4/-6
simplify
m=-2/3
y-y1=m(x-x1)
y-(-1)=-2/3(x-4)
y+1=-2/3(x-4)
y+1=-2/3x+8/3
y=-2/3x+8/3-1
y=-2/3x+8/3-3/3
y=-2/3x+5/3
y-(-2/3x)=5/3
y+2/3x=5/3
2/3x+y=5/3
3(2/3x+y)=3(5/3)
2x+3y=5
2x+3y-5=0
Answer:
Step-by-step explanation:
we would like to figure out the derivative of the following:
to do so, let,
By simplifying we acquire:
use law of exponent which yields:
take derivative in both sides:
use sum derivation rule which yields:
By constant derivation we acquire:
use exponent rule of derivation which yields:
simplify exponent:
two negatives make positive so,
<h3>further simplification if needed:</h3>
by law of exponent we acquire:
simplify addition:
and we are done!
