Answer:
Step-by-step explanation:
Let's assume this is a straight line, so we can use the basic form of a straight line equation: y=mx+b, where m is the slope and b is the y-intercept (the value of y when x is zero).
The slope is the rate of change of the line, and can be calculated by dividing the change in y by the change in x between any two points. Here: (0,4) and (1,2)
The change in y is known as the "Rise." Going from (0,4) to (1,2), we have a change of -2:
(2 - 4) = -2 This is the Rise (Final minus the initial values)
X changes by 1 (1-0) = 1 (Final minus the initial values)
Rise/Run = -2/1 or -2
The slope, m, is -2. Values of y decrease as x increases.
The equation becomes y = -2x+b
The value of b must be such it forces the line to go between the two points. We can calculate b by i=using one of the two points in out unfinished equation and solve for b. I'll pick (1,2).
y = -2x+b
2 = -2*(1) + b
b = 4
The equation becomes y=-2x+4

Given the function
(Round to 1 significant number)
Sec Ф=1/cos Ф=cos⁻¹Ф
correct answers: a. sec Ф=cos⁻¹Ф and d. sec Ф=1/ cos Ф
Please try leaving out the "I'm so bad at math" part. It doesn't help.
The given inequality is <span>4x + y > −6. Because of the > symbol, we must use a dashed line, not a solid one. Let's solve this for y: y > -4x - 6.
This (dashed) line has a slope of -4 and a y-intercept of (0,-6).
Plot (0,-6). Then, with your pencil pt. on that, move 1 unit to the right and then 4 units down. Plot a new point there, at (1, -10). Draw your dashed line thru those 2 pts. Then, because we have y > -4x - 6, shade the area ABOVE this line. Done.</span>
Answer:
9.916...
Step-by-step explanation: (The "6" is repeating)
Divide using long division. The whole number portion will be the number of times the denominator of the original fraction divides evenly into the numerator of the original fraction, and the fraction portion of the mixed number will be the remainder of the original fraction division over the denominator of the original fraction.
This gives us a mixed number-fraction: 9 and 11/12.
If we then turn this into a simplified fraction, then it becomes 119/12. Turn <em>that</em> into a decimal by dividing the numerator by the denominator.
This gives us our answer of 9.916...!!! <em>Hope that helps!</em>
