Answer:
X = 6
Step-by-step explanation:
DU = DU .....(1)
DV =DW ......(2)
angle VDU = angle WDU .......(3)
so triangle VDU and triangle WDU are Congruent Triangles
thus VU = WU
we solve : 9x + 1 = 7x + 13 , x = 6
<span>Using processing software (Excel) or even a decent scientific calculator. You input the values and generate the best fit cubic equation.
For number 1, the equation is
y = 8x10</span>⁻⁵ x³ - 0.0097 x² + 0.374 x + 1.083
where x is the number of years since 1900
y is the pounds cheese consumed
For number 2, the equation is
y = -3x10⁻⁵ x³ + 0.0028 x² + 0.2155 x + 1.7736
For number 3
P(-1) = 18
There is one solution to this system of equations. The answer is B.
Answer:
x=-4
When x is -4, the y value (which is what the function spits out) is 8.
