Hello! Remember you have to write complete questions in order to get good and exact answers. Here we have no expressions for ∠CBD and ∠ABC, so I'll assume:
We know that the measure of ∠CBD is 45% of the measure of ∠ABC, then:
9514 1404 393
Answer:
- no solutions
- 1, 14=0
- 2, 7=0
Step-by-step explanation:
The first blank is correctly filled with "no solutions."
The two requested values of x can be <em>any numbers of your choice</em> (except 0). Above, we have chosen x=1, which makes the equation 14/1 = 0, or 14 = 0 when simplified.
And we have chosen x=2, which makes the equation 14/2 = 0, or 7 = 0 when simplified.

In short, there are <em>an infinite number of correct answers</em> to this question.
X + y = 15
xy = -312
x + y = 15
x - x + y = -x + 15
y = -x + 15
xy = -312
x(-x + 15) = -312
x(-x) + x(15) = -312
-x² + 15x = -312
-x² + 15x + 312 = 0
-1(x²) - 1(-15x) - 1(312) = 0
-1(x² - 15x + 312) = 0
-1 -1
x² - 15x + 312 = 0
x = -(-15) ± √((-15)² - 4(1)(312))
2(1)
x = 15 ± √(225 - 1248)
2
x = 15 ± √(-1023)
2
x = 15 ± 31.984i
2
x = 7.5 ± 15.992
x = 7.5 + 15.992 or x = 7.5 - 15.992
x = 23.492 or x = -8.492
x + y = 15
23.492 + y = 15
- 23.492 - 23.492
y = -8.492
(x, y) = (23.492, -8.492)
or
x + y = 15
-8.492 + y = 15
+ 8.492 + 8.492
y = 23.492
(x, y) = (-8.492, 23.492)
The two numbers that add up to 15 and mutliply to -312 are -8.492 and 23.492.
Answer:
9
Step-by-step explanation:
We know that
The balls hits the ground when h(t)=0, so
Note I only considered the positive case because time must be positive.
