Answer:
k = 1
Step-by-step explanation:
<u>Discriminant</u>




As we need to determine the value of k that will give <u>one solution</u>, set the <u>discriminant to zero</u>.
<u>Given equation</u>:

Therefore:
Substitute these values into the discriminant and solve for k:

Answer: the two numbers are 6 and 11.
Set up the individual equation according to the verbal statements:
<em>A positive number is 5 less than another positive number:</em>
a = b - 5 (this also implies that a<b)
<em>Six times the lesser number minus 3 times the greater number is 3. </em>

<em>Find the two positive numbers.</em>
This is a system of linear equations - solve for a and b:
<em>
</em>
Answer:
86
Step-by-step explanation:
y + 28 + 58 = 180
y + 86 = 180
y = 180 - 86
y = 94
x + y = 180
x + 94 = 180
x = 180 - 94
x = 86
1 and 1/8 miles. 1/3 is 3/8 of a mile. This 3/3 is 9/8 miles
A is the correct answer.
Point Slope Form: y - y₁ = m(x - x₁)
m = slope ⇒ -4/7
Coordinate: (-1 , 4)
x₁ y₁
All you have to do is plug in all of the information above into the formula.
y - 4 = -4/7(x +1)
