Answer:
Laila assumed that the lines that formed the angles x and 18° added up to 90. This is in fact false because of the lack of the square marking to signify it as a right or 90 degree angle.
Answer:
y1 = √x - 3
y2 = √x - 1
Step-by-step explanation:
To quickly solve this problem, we can use a graphing tool or a calculator to plot the equations.
Please see the attached image below, to find more information about the graph
s
The equations are:
y1 = √x - 3
y2 = √x - 1
y3 = √(x+1)
y4 = √(3x-3)
Based on the image below, the possible choices would be
the functions
y1 = √x - 3
y2 = √x - 1
Answer:
The missing sum is 48
Step-by-step explanation:
Assume the missing sum is x
The equation can be rewritten as
8/9 = x/54
By cross multiplying, we will have
9 × x = 8 × 54
9x = 432
Divide both sides by 9
x = 432/9
x = 48
Answer:
I want to say option B - Congruent.
Let t, h, b represent the weighs of tail, head, and body, respectively.
t = 4 . . . . given
h = t + b/2 . . . . the head weighs as much as the tail and half the body
b/2 = h + t . . . . half the body weighs as much as the head and tail
_____
Substituting for b/2 in the second equation using the expression in the third equation, we have
... h = t + (h + t)
Subtracting h from both sides gives
... 0 = 2t . . . . . . in contradiction to the initial statement about tail weight.
Conclusion: there's no solution to the problem given here.
