Answer:
x = 21
Step-by-step explanation:
ALL triangles add up to 180 degrees
180 = 22 + 57 + (5x - 4)
180 = 79 + (5x - 4)
101 = 5x - 4
105 = 5x
21 = x

Write an inequality that represents t, the number of minutes after the start of the hike, when the hiker’s elevation was higher than 5 feet above sea level.
Answers
Answer:
15t - 50 > 5Step-by-step explanation:
Initial point = -50 ftClimbing rate = 15 ft / minTime = tRequired inequality:
15t - 50 > 5Solution:
15t > 55t > 55/15t > 3 10/15 = 3 40/60 min = 3 min 40 secondsAnswer:
Solution given:
Initial point = -50 ft
Climbing rate = 15 ft/min
Time = t(let)
So Required inequality:
15t-50 > 5
adding 50 on both term
15t> 55
dividing both term by 15
t > 55/15

Consider the quadratic equation 3x^2-6=2x. (a) What is the value of the discriminant? (b) What does the discriminant of the quadractic equation tell about the solutions to 3x^2-6=2x?
Answers
Answer:
(a) discriminant is positive, 76
(b) the above tells you there are two real roots
Step-by-step explanation:
the discriminant is 'b² - 4ac'
3x² - 2x - 6 = 0 ∴ a = 3, b = -2, c = -6
(-2)² - 4(3)(-6) = 4 + 72
(a) The discriminant of the quadratic equation is positive, 76.
(b) The quadratic equation tells you there are two real roots.
What is a quadratic equation?A quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.
The discriminant of a polynomial in mathematics is a quantity that depends on the coefficients and enables inference of some root features without computing them.
Given that the quadratic equation 3x²-6=2x.
The discriminant Of the quadratic equation is calculated by the formula below:-
D = b² - 4ac
3x² - 2x - 6 = 0 ∴
a = 3, b = -2, c = -6
Put the value of the coefficient to get the value of the discriminant.
D = (-2)² - 4(3)(-6) = 4 + 72 = 76
Therefore, the discriminant of the quadratic equation is positive, 76, and the quadratic equation tells you there are two real roots

Answer:
31 - 5i
Step-by-step explanation:
(7 - 3i) * (4 + i)
Step 1: Multiply complex numbers 7 − 3i and 4 + i like you multiply binomials.
7 * 4 + 7i - 3i * 4 - 3i²
Step 2: By definition, i² is -1.
7 * 4 + 7i - 3i * 4 - 3 ( - 1)
Step 3: Do the multiplications.
28 + 7i - 12i + 3
Step 4: Combine the real & imaginary parts.
28 + 3 + (7 - 12)i
Step 5: Do the additions.

If the perimeter is 650 units, what is the value of x?
Answers
Given:
The three sides of a triangle are:
[tex](x-8),(4x^2-3),(4x^2+4)[/tex]
The perimeter of the triangle 650 units.
To find:
The value of x.
Solution:
Perimeter of a triangle is the sum of all three sides of the triangle. So,
[tex]Perimeter=(x-8)+(4x^2-3)+(4x^2+4)[/tex]
[tex]Perimeter=8x^2+x-7[/tex]
The perimeter of the triangle 650 units.
[tex]8x^2+x-7=650[/tex]
[tex]8x^2+x-7-650=0[/tex]
[tex]8x^2+x-657=0[/tex]
Splitting the middle term, we get
[tex]8x^2+73x-72x-657=0[/tex]
[tex]x(8x+73)-9(8x+73)=0[/tex]
[tex](x-9)(8x+73)=0[/tex]
Using zero product property, we get
[tex](x-9)=0\text{ and }(8x+73)=0[/tex]
[tex]x=9\text{ and }x=-\dfrac{73}{8}[/tex]
For negative value of x, the side [tex](x-8)[/tex] will be negative, which is not possible because the side of a triangle cannot be negative.
Therefore, the only value of x is 9.
