Answer:
y = mx + b
y = -2x + 4
Step-by-step explanation:
m = 2 - 4 / 1 - 0 = -2 / 1 = -2
m (slope) = -2
y = mx + b (0,4)
4 = -2x + 0
<u>-0 - 0</u>
<u>4</u> = <u>-2x</u>
-2 -2
-2 = x
Equation: y = mx + b
y = -2x + 4

4. If the determinant delta of a quadratic equation is positive, the equation has two real roots. If the determinant is negative, it has two imaginary roots. In this case, delta=b^2-4ac=(-1)^2-4*1*4=-15. Therefore, this equation has two imaginary roots.
Answer:
No
Step-by-step explanation:
The set contains 2 different ranges for 1 domain. In this case, X = 1 returns 5 and -3, meaning it cannot be a function.
Answer:
74.31353
=74 m
Step-by-step explanation:
given that three locations are marked next to a river. Points B and C are on the same side of the river, and point A is on the other side of the river. To find the distance AB across a river, a distance BC of 241 meters is laid off on one side of the river. It is found that the angle at point B is 108.6° and the angle at point C is 14.9°.
we have information about triangle ABC as side BC =241, Angle B = 108.6 and angle C = 14.9 degrees.
Hence this is an obtuse scalene triangle.
Angle ∠A = 56.5° (III angle)
Using sine formula we get
So distance AB is 74 metres.
The toppings would still cost 0.50 each (since it is just toppings)
The large pizza costs $18 if you do not have any toppings
The medium costs half of the large
18/2 = 9
The medium costs $9 without any toppings, so your new equation will be:
c = 0.50t + 9
hope this helps
