Answer:
25, -55
Step-by-step explanation:
Intercepts are where the line crosses the x and y axis
x intercept = 25
y intercept = -55
Answer:
32 Hamsters and 18 Birds
Step-by-step explanation:
B+H=50
2B+4H=164
H=50-B
4(50-B)+2B=164
200-4B+2B=164
200-2B=164
-2B=164-200
-2B=-36
-2B/-2=-36/-2
B=18

50-18=32
H=32

CHECK: 18+32=50
CHECK: 18 X 2=36 LEGS
CHECK: 32 X 4= 128 LEGS
CHECK: 128+36=164 LEGS IN TOTAL
Answer:
A :)
Step-by-step explanation:
I believe the answer is A because on a line it equals 180 and because the angle of 8 is equal to 171, you still need to find 9 more degrees. You set 2x-33 equal to 9 and solve as a two step equation, and get the answer 21. Hope this helps :)
Answer:
i. + 26x + 144 - 299 = 0
ii. x = 5
Step-by-step explanation:
The area of the figure = 299 cm²
The figure has a shape of a rectangle, so that;
Area of rectangle = length x width
length of the figure = 18 + x
width of the figure = 8 + x
Area of the figure = (18 + x) x (8 + x)
299 = (18 + x) x (8 + x)
299 = + 26x + 144
+ 26x + 144 - 299 = 0
+ 26x - 155 = 0
applying the trigonometric formula;
x = (-b ± ) ÷ 2a
= (-26 ± ) ÷ 2
= (-26 ± ) ÷ 2
= (-26 ± ) ÷ 2
= (-26 ± 36) ÷ 2
x = (-26 + 36) ÷ 2 OR x = (-26 -36) ÷ 2
= 10 ÷ 2 OR -62 ÷ 2
= 5 OR -31
Thus, x = 5
