Answer:
This equation has 4 solutions, its real solutions are x = -1 and 3
Step-by-step explanation:
Correct for Plato Users
The equation has 4 solutions and its real solutions are 3, -1.
The given polynomial equation is 6(x - 3)(x² + 4)(x + 1) = 0.
What does a real solution mean in math?A real solution in algebra is simply a solution to an equation that is a real number.
Now, 6(x - 3)(x² + 4)(x + 1) = 0
⇒(x - 3)(x² + 4)(x + 1) = 0
⇒(x - 3)=0, (x² + 4)=0 and (x + 1) = 0
⇒x=3, -1 and ±√-4.
Therefore, the equation has 4 solutions and its real solutions are 3, -1.

You are a contractor and charge $65 for a site visit plus an additional $15 per hour for each hour you spend working at the site. Write and solve an equation to determine how many total hours you have to work to earn $950 working at two separate work sites.
Answer:
54.6 hours
Step-by-step explanation:
65x2 is 130 130-950 is 820 then 820 divided by 15 is 54.6 therefore meaning you have to work 54.6 hours to get 950$ you can check this by doing 54.6x15+130, might not be exact because i rounded to the nearest tenth.

Write an equation of the line that passes through point (−3, 8) and has the slope m=−2.
Answer:
y=-2x+8
Step-by-step explanation:
slope formula is y=mx+b
slope(m)=-2, and y-value(b)=8
so ya just plug in what ya know to get y=-2x+8
The equation of the line that passes through point (−3, 8) and has the slope m=−2 is [tex]y=-2x+2[/tex]
What Is y = mx + c?The slope-intercept form of the equation of the line is represented by the equation y = mx + c. It requires the line's y-intercept and slope value, "m." We must first comprehend the line's slope m and y-intercept in order to comprehend this equation for the line.Slope: The letter "m" stands for the line's gradient or slope. The slope here could be zero, positive, or negative. With reference to the x-axis, the tangent of this line's angle of inclination can likewise be used to compute the slope.Intercept: The term "intercept" in this equation refers to the value "c," which is the line's starting point. The length of the line's y-axis intersection, measured from the origin, is known as the intercept. It can also be thought of as the line's intersection point at (0, c) on the y-axis.The slope formula can be used to create the equation y = mx + c. Here, we choose a random point (x, y) on the line and a point (0, c) on the y-axis. We try to determine the slope'm' of the line using these two points. The slope of the line is equal to the difference between the two points' y coordinates divided by the difference between their x coordinates.m = (y - c)/(x - 0) mx = y - c and m = (y - c)/xy = mx + c So, using the formula for the slope of a line, we can successfully deduce the slope-intercept form of the equation of a line.Given, x= -3, y = 8 and m = -2
usiny y =mx+c
we get,
8 = -2*-3+c
8 = 6+c
c = 8-6 = 2
Therefore, The equation of the line that passes through point (−3, 8) and has the slope m=−2 is [tex]y=-2x+2[/tex]

Rena’s grandfather opened a savings account as a college fund for her. His initial deposit and the yearly simple interest rate are shown.
A college graduate is shown walking up stairs. The bottom step represents three thousand five hundred dollars. The value of the top step is unknown. The distance up the stairs is labeled four years. The simple interest rate is three point two five percent.
How much will Rena have in this account after 4 years?
Enter the correct answer in the box.
Answer:
Total amount (A) = $3,955
Step-by-step explanation:
Given:
Initial deposit (P) = $3,500
Rate of interest (r) = 3.25%
Number of years (t) = 4
Find:
Total amount (A)
Computation:
Simple interest = (p)(r)(t)
Simple interest = (3,500)(3.25)(4)
Simple Interest = $455
Total amount (A) = Initial deposit (P) + Simple Interest
Total amount (A) = 3,500 + 455
Total amount (A) = $3,955

Problem 1
Answer: x = 9
----------
Explanation:
For now focus on triangle DEF. We need to find the missing angle D.
D+E+F = 180
D+71+42 = 180
D+113 = 180
D = 180-113
D = 67
In order for DE to be parallel to GH, the alternate interior angles EDF and GHF must be congruent
Let's see what happens when we force them to be equal
angle EDF = angle GHF
67 = 5x+22
67-22 = 5x
45 = 5x
5x = 45
x = 45/5
x = 9

Problem 2
Answers:
Converse: "if it is winter, then it is snowing"
Inverse: "If it is not snowing, then it is not winter"
Contrapositive: "If it is not winter, then it is not snowing"
----------
Explanation:
The original conditional is in the form "If P, then Q". The P and Q are placeholders for logical statements.
We then have the following forms
converse = "if Q, then P" (swap P and Q)inverse = "If not P, then not Q" (negate each)contrapositive = "If not Q, then not P" (do both inverse and converse operations)==========================================
Problem 3
Answer: choice B) "If the sum of two angles is not 180 degrees, then they aren't supplementary"
----------
Explanation:
Refer to problem 2 for the general form of the inverse. We negate each of the P and Q to get our final answer.
==========================================
Problem 4
Answer: Choice C) "If I do not need an umbrella, then it is not raining"
----------
Explanation:
Refer to problem 2 for the general form of the contrapositive. We swap P and Q, and negate each.

At the amusement park, the Ferris wheel is located 95 feet east and 156 feet north of the entrance. The swings are located 23 feet west and 124 feet north of the entrance. If Jalen is standing exactly three-eights the distance from the Ferris wheel to the swings, to the nearest hundredth of a foot, find the direct distance between Jalen and the entrance.
Answer:
113.18
Step-by-step explanation:
[tex]\sqrt{113^{2}+32x^{2}[/tex]
SF=113.18
The direct distance between Jalen and the entrance is 144.6 feet.
What is distance?The distance of an object can be defined as the complete path travelled by an object .Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion.
Given:
Place everything on an xy grid with the Entrance at (0,0).
Then the Ferris Wheel is at (95,156) and the Swings are at (-23,124).
Cody is halfway between them,
so he is at
(95-((95-(-23)/2)),156-(156-124/2) or (36,140).
The distance from Cody to the entrance, using Pythagoras, is square root of
(362+1402)
=144.6 feet
Therefore , the direct distance between Jalen and the entrance is 144.6 feet.

y=4x+8x, Solve for x.
It's x=y/12, I just need to know how to work it out.
Step-by-step explanation:
Answer:-[tex]\tt{y = 4x+8x}[/tex]
First, we need to add up the x.
We know that 4+8 = 12, so
[tex]\tt{4x+8x=12x}[/tex]
Now, equating it to y,
[tex]\tt{y = 12x}[/tex]
Now, if I multiply [tex]\tt{\dfrac{1}{12}}[/tex] on both sides,
I get,
[tex]\tt{\dfrac{y}{12}= \dfrac{\cancel{12}x}{\cancel{12}}}[/tex]
Now, as 12 got cancelled , I got the final answer as
[tex]\boxed{\tt{x =\dfrac{y}{12}}}[/tex]
Hope it helps :)
