Answer:
cannot be determined
Step-by-step explanation:
you know they are similar triangles because their angles are congruent, but you cannot determine if they are the same because you are not given that any of their sides are congruent
Yes, it is an equivalent fraction
Answer: there are 50 humans and 24 horses.
Step-by-step explanation:
Let x represent the number of humans in the horse racing area.
Let y represent the number of horses in the horse racing area.
He counted 74 heads. A human has one head and a horse also has one head. It means that
x + y = 74
He counted 196 legs. A human has 2 legs and a horse has 4 legs. It means that
2x + 4y = 196 - - - - - - - -- - -1
Substituting x = 74 - y into equation 1, it becomes
2(74 - y) + 4y = 196
148 - 2y + 4y = 196
- 2y + 4y = 196 - 148
2y = 48
y = 48/2 = 24
x = 74 - y = 74 - 24
x = 50
The answers would be A, D, E, and F because they all have the same y-intercept, the y-intercept is the second number in the equation
Answer:
x^2 +13x+22 =0
Step-by-step explanation:
Subtract the zero from x
(x- -11) (x- -2) =0
(x+11) (x+2) = 0
Foil
x^2 +2x+11x+22 =0
Combine like terms
x^2 +13x+22 =0
