Find the value of x. Round to the nearest degree.
9514 1404 393
Answer:
x° = 42°
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the useful relation ...
Cos = Adjacent/Hypotenuse
cos(x°) = 4.0/5.4
x° = arccos(4.0/5.4) ≈ 42.21°
The value of x is about 42.

What is the equation of the line that passes through the point (-4, -7) and has a
slope of 2/3 ?
Answer:
Step-by-step explanation:
(-4 , -7) ; slope = (2/3)
y -y1 =m(x-x1)
[tex]y -[-7]=\frac{2}{3}(x-[4])\\\\y+7 = \frac{2}{3}(x+4)\\\\y+7=\frac{2}{3}x+4*\frac{2}{3}\\\\y +7 = \frac{2}{3}x+\frac{8}{3}\\\\y=\frac{2}{3}x+\frac{8}{3}-7\\\\y=\frac{2}{3}x+\frac{8}{3}-\frac{7*3}{1*3}\\\\y=\frac{2}{3}x+\frac{8}{3}-\frac{21}{3}\\\\y=\frac{2}{3}x-\frac{13}{3}[/tex]

— 3х + 9y = — 21
— 3х +8y = -18
find the solution by system of equations
Answer:
x=-2,y=-3
Step-by-step explanation:
x=7+3x
-3x+8y=-18
-21-y=-18
x=7+3x
y=-3
x=7+3x
x=-2
y=-3
Answer:
x = -2
y = -3
Step-by-step explanation:
There are three methods for solving system of equations: elimination, substitution, and graphing. In this case elimination would be the best method since you have -3x for both equations. When solving by elimination, your goal is to eliminate one of the variables, in this case we will eliminate x. Subtract the bottom equation from the top (it is important to remember here that the negative will distribute to the entire equation).
-3х + 9y = -21
- (- 3х +8y = -18)
_____________
y = -3
Now plug this y-value in to either equation and solve for x
-3х + 9y = -21
-3х + 9(-3) = -21
-3x - 27 = -21
-3x = 6
x = -2
Check your answer by plugging both values in to the second equation
- 3х +8y = -18
- 3(-2) +8(-3) = -18
6 - 24 = -18
-18 = -18

3000? maybe good luck
Answer:
6,000
Step-by-step explanation:
To find the volume, you have to solve the width x length x height.
So, 1 of the containers is 20(W) x 15(L) x 10(H) which equals to a volume of 3,000.Then we have another container with the same dimensions. That means we will add 3,000 because it's the same. 3,000 + 3,000 = 6,000

Answer:
a = 5 c =11
Step-by-step explanation:
Answer:
sqrt[(80^2) + (20^2)] = (bottom base of the entire rectangle)
= 20(sqrt(17)) units or about 82.46211 units
find angle at bottom corner
arctan(20/80) = about 14.04624 degrees
cos(14.04624) = 20(sqrt17) / (80+a)
solve for a: --> a = 5 units
use pythag for side c
(20^2) + (5^2) = c^2
c is about 20.6155 units or 5(sqrt17)

===> 45m - 9m < -11 + 42
==> 36m < 31
==> m < 31/36
hence the value of m < 31/36
