Answer:
y = x+5 This equation satisfies all the four sets of x and y values 1.When x = 5,y = x+5 = 5+5 = 10 2.When x = 10,y = x+5 = 10+5 = 15 3.When x =15,y = x+5 = 15+5 = 20 4.When x = 20,y = x+5 = 20+5 = 25 Hence,
Step-by-step explanation:
Isolate one term (x or y) in one of the equations
6x+6y=0
6x=-6y
X= -1y
Substitute x=-y into the other equation
-7(-y) + 2y =18
7y + 2y =18
9y=18
Y=2
Substitute y=2 into 6x+6y=0
6x + 6(2) = 0
6x + 12=0
6x= -12
X = -2
Answer:
x = 12.52°
Step-by-step explanation:
The illustration forms a right angle triangle . The right angle triangle formed has a height of 200 ft and a base of 900 ft.
The opposite side of the triangle is 200 ft while the adjacent side of the triangle is 900 ft.
Using tangential ratio we can find the angle of depression. Therefore,
Let
x = angle of depression
tan x = opposite/adjacent
opposite = 200 ft
adjacent = 900 ft
tan x = 200/900
tan x = 2/9
x = tan⁻¹ 2/9
x = tan⁻¹ 0.222
x = 12.5166739144
x = 12.52°
Answer:
m∠B=79°
Step-by-step explanation:
∠A +∠B+∠C+∠D=360°
14x-11+8x+7+5x+18+10x+13=360°
37x+27=360°
37x=333
x=9
so,
m∠B=8x+9
m∠B=8×9+7
m∠B=79°
Hope it helps!
Answer:
$22.50
Step-by-step explanation:
50/100 = x/45
cross multiply
50 × 45 = 100 × x
2250 = 100x
divide both sides by 100
22.5 = x
*note: marksup the price means that $45 should be more than what the value of x is. $45 is more than $22.50. you can also check your work by looking at the fact $22.50 is exactly half (50%) the amount of $45*
