Answer:
x=2
Step-by-step explanation:
first distribute the 1/2
1/2x - 5=-4
then add 5 to both sides
1/2x=1
multiple by 2 on both sides
x=2
Big ifs, question writers. These are of course approximations.
The "co" in cosine comes from complementary angles. It means since
Answer: cos 48° = 2/3
Similarly,
Answer: tan 69.5° = 8/3
Answer:
The value underneath 6 is -27 and the value underneath 7 is -32
Step-by-step explanation:
In order to find these, we first need to model the equation. We can do that by using the two points we have to find the slope.
m (slope) = (y2 - y1)/(x2 - x1)
m = (-7 - -17)/(2 - 4)
m = 10/-2
m = -5
Now we can find the intercept by using either point and slope intercept form.
y = mx + b
-7 = -5(2) + b
-7 = -10 + b
3 = b
Now we can model the equation using those two pieces.
y = -5x + 3
With this modeled, we can plug 6 and 7 in for x to find the outputs.
y = -5x + 3
y = -5(6) + 3
y = -30 + 3
y = -27
y = -5x + 3
y = -5(7) + 3
y = -35 + 3
y = -32
Since it's an estimation, round 3.24 to the nearest whole number, which is 3, then just divide, the answer is 0.06586..... Did you mean 82 divided by 3.24? (82÷3.24 or 3.24/82) then, round 3.24 to 3 and divide, the answer is 27.333 or 27.
