Answer:
slope=3
y-intercept=10
Step-by-step explanation:
this is really easy to learn. keep the formula y=mx+b in your head. m is the slope, and b the y-intercept. let y and x be remain the variables.
I believe x=116 and z=26. 4z-40=64
4z=104
z=26
180-64=116
I hope I can show the image, but I hope this may help you, the answer is:
The center of the inscribed circle of ΔABC is <u>point S</u> , and the center of the circumscribed circle of ΔABC is <u>point P.</u>
The area of triangle ABC from the given vertices is gotten as; 7.5
<h3>How to find the area of a triangle?</h3>
We are given the vertices of the triangle as;
A(1, 2)
B(4, 0)
C(1,-4)
The formula for area of a triangle with 3 vertices is;
Area = ¹/₂[x₁(y₂ - y₃) + x₂(y₃ - y₁) + x₃(y₁ - y₂)]
Thus;
Area = ¹/₂[1(0 + 4) + 4(-4 - 1) + 1(1 - 0)]
Area = ¹/₂(4 - 20 + 1)
Area = -7.5

Answer: 2,125 whales
because half of the ten whales in the sample were infected, then half of the population would likely be infected. 4,250/2=2,125
