Answer:
The first one can be simplified, but the second one cannot be (that i know of). The first one simplified would be 9 to the power of 8.
Step-by-step explanation:
Answer:
x = 7
Step-by-step explanation:
The angle adjacent to the 70 degree angle is also 70 degrees. We assume that there are four 90-degree angles in the center of the figure. Thus, 8x - 36 + 70 + 90 = 180 (the sum of the interior angles is 180 degrees).
Solving 8x - 36 + 70 + 90 = 180 for x:
8x - 36 = 20, or 8x = 56.
Dividing both sides by 8 yields x = 7.
We know that
if <span>Amy pays 24.50 for 7 tickets
so
cost each ticket is=24.50/7-----> </span>£<span>3.50
find the total number of tickets=</span>£63/£3.50-----> 18 ticket
let
x-----> <span>amount of tickets purchased by Dan
</span>18=7+x -----> x=18-7-----> x=11
the answer is
11
Answer:
x = 41.81°, 138.19°, 210°, 330°
Explanation:
3cos(2x) + sin(x) = 1
subtract one from both sides
→ 3cos(2x) + sin(x) − 1 = 0
rewrite using trigonometry identities
→ 2 + sin(x) − 6sin²(x) = 0
solve x by substitution
f(x) = 2 + sin(x) − 6sin²(x)
= 2 + 4sin(x) - 3sin(x) − 6sin²(x)
= −2sinx(3sinx −2) − (3sinx−2)
= (3sinx −2)(−2sinx−1)
= −(3sinx −2)(2sinx+1)
f(x) = 2 + sin(x) − 6sin²(x) = 0
= −(3sinx −2)(2sinx+1) = 0
(3sinx −2) = 0 (2sinx+1) = 0
→sinx = 2/3 →sinx = −1/2
x = 41.81°, 138.19° x = 210°, 330°

Answer:
y = -4/3x +8
Step-by-step explanation:
Slope intercept form is
y = mx+b where m is the slope and b is the y intercept
4x+3y = 24
Subtract 4x from each side
3y = -4x+24
Divide each side by 3
y = -4/3x +24/3
y = -4/3x +8
