Answer:
-0.9
Step-by-step explanation:
-0.9 × 100 = -90
answer : -90 = -100+x → x = 10
explanation : to solve for x, you are simplifying both sides of the equation, then isolating the variable.
step 1 : move the variable to the left-hand side and change its sign.
ex : -90-x = -100
step 2 : move the constant to the right-hand side and change its sign.
ex : -x = -100+90
step 3 : calculate the sum
ex : -x = -10
step 4 : change the signs on both sides of the equation
ex : x = 10
solution : x=10
hope this helps !

Find the median and mean of the data set below:
11,2,44, 49, 33, 41
What is the Median
Mean is 30
Answer:
2 11 33 41 44 49
Step-by-step explanation:
33+41=74 74÷2=37
Answer: The medians the middle, so you put in order to 2, 11, 33, 41, 44, and 49. Then, you just pick the number in the middle and since it's 33 and 41, you add them together then divide by 2 and you answer is 37. I hope this helps you!

If the solution to a linear system of equations is x=6 and y= 2 and you graphed the two equations, where would the two lines intersect? How do you know?
Answer:
(6,2)
Step-by-step explanation:
Combine them
Answer:
Step-by-step explanation:
A system of equations is a set of two or more equations that represent a relationship between two or more variables. A solution of this system is an ordered pair that satisfies each equation in the system. Finding the set of all solutions is called solving the system of equations. Solving a system of equations by graphing is exactly what the name implies – graph both equations, and their point(s) of intersection is the solution. A system of linear equations only have one solution because each equation is a straight line, they will only have one point of intersection (unless, of course, they are the same line).
THE TWO LINES WOULD INTERSECT (6, 2). BECAUSE THE SOLUTION IS THE INTERSECTION..

Given that AB is a line segment and the angle
y
= 67°, work out the value of the angle marked
x
Answer:
x = 113°
Step-by-step explanation:
AB is a line segment and hence it is a straight line which means it is a straight angle, so it is 180° .
y = 67°
x = ?
So, x + y = AB
=> x + 67° = 180°
=> x = 180° - 67°
=> x = 113°
Therefore, x = 113°

Help me please please please it’s due tonight!!!!!!!!!!!
Answer:
A. (4, 18)
Step-by-step explanation:
The "y" coordinate of the midpoint will be equal to the average of the y coordinates of the endpoints, and the x coordinate of the midpoint will be equal to the average of the x coordinates of the endpoints, and so we get that...
The x coordinate of the midpoint = (5 + 3) / 2 = 8 / 2 = 4
The y coordinate of the midpoint = (21 + 15) / 2 = 36 / 2 = 18
So the right answer is A (4, 18)
The discriminant of the equation x^2 - 4x + 4 = 0 shows there will be solution(s).
1. one real
2. one imaginary
3. two imaginary
4. no real or imaginary
Answer:
one real
Answer: 1
Step-by-step explanation:
Givens
a = 1
b = -4
c = 4
Discriminate
Discriminate = sqrt(b^2 - 4*a*c)
Discriminate = sqrt( (-4)^2 - 4 * (1)(4) )
Discriminate = sqrt ( 16 - 16)
Discriminate = sqrt(0)
Discriminate = 0
That means the 1 real root is - b / 2a = 4/(2*1) = - -2 = 2

20, 21, 29 represents three sides of a right triangle
Step-by-step explanation:
By Using Pythagorean Triplet we can say that
20, 21, 29 represents three sides of a right triangle
FOR VERIFICATION ONLY:(20)² + (21)² = (29)²
400 + 441 = 841
841 = 841
Thus, 20, 21, 29 represents three sides of a right triangle

find the zeros of the function !! g(x)=(x-2)(3x+3) lesser x= ?
greater x= ?
Answer:
Step-by-step explanation:
Rewrite this function as g(x) = 3(x + 1)(x - 2)
Set each factor equal to zero in turn, solving for x each time:
x + 1 => x = -1 (the lesser zero)
x - 2 => x = 2 (the greater zero)
Answer:
lesser x =-1
greater x =2

1) The graph of g(x) is shown below. Which statement given below is FALSE?
Please help!
=======================================================
Explanation:
Let's go through the answer choices one by one to see which are true, and which are false.
Choice A) This is true because as we approach x = 2 from the left hand side, the y values get closer to y = 1 from the top Choice B) This is true. As we get closer to x = 4 on the left side, the blue curve is heading downward forever toward negative infinity. So this is what y is approaching when x approaches 4 from the left side.Choice C) This is true also. The function is continuous at x = -3 due to no gaps or holes at this location, so that means its limit here is equal to the function value. Choice D) This is false. The limit does exist and we find it by approaching x = -4 from either side, and we'll find that the y values are approaching y = -2. In contrast, the limit at x = 2 does not exist because we approach two different y values when we approach x = 2 from the left and right sides (approach x = 2 from the left and you get closer to y = 1; approach x = 2 from the right and you get closer to y = -2). So again, the limit does exist at x = -4; however, the function is not continuous here because its limiting value differs from its function value.Choice E) This is true because the function curve approaches the same y value from either side of x = 6. Therefore, the limit at x = 6 exists.Which of the following functions has a vertex of (-1,2)?
Choose 3.
f(x) = (x + 1)^2 + 2
g(x) = x^2 - 1x + 2
h(x) = -x^2 + 2
r(x)= x^2+2x+3
t(x) = -(x + 1)^2 + 2
Answer:

A pillow costs 30 dollars, you have a 20% coupon. How much will it cost
with the discount? *
Answer:
$24
Step-by-step explanation:
100% - 20% = 80%
Since the coupon is for 20% of the price, you will only pay the remaining 80% of the price.
80% of $30 = 0.8 * $30 = $24
Answer: $24
Benjamin traveled at an average speed of 65 miles per hour for 4.5 hours and then traveled at an average speed of 70 miles per hour for 3.5 hours. What was the total distance in miles that Benjamin traveled during this time?
Answer:
542 miles
Step-by-step explanation:
65 miles/hour x 4.5 hours = 297 miles for the first part
70 miles/hour x 3.5 hours = 245 miles for the second part
297 + 245 = 542 miles
Which inequality could it be?
Answer:
95 < 60.5 + 3x
Step-by-step explanation:
60.5 + 3x represents how much he will pay each month and wants to keep that under 95, hence the less than sign
Both Phoebe and Connor are trying to maximize their lifetime income. Each has a different plan on how to do this best:
Phoebe claims that she wants a career with no college or trade school requirements because she could save the money for retirement rather than spending it on education. She estimates her average yearly salary at $35,000 per year with no post-secondary education requirements.
Connor claims post-secondary education will help him get a career with a higher salary and more benefits that he can use in retirement, so the education costs will more than pay for themselves. Connor estimates paying $80,000 for his post-secondary education and an average yearly salary of $60,000 per year after he earns his college degree.
Which statement about their claims is correct?
A. Phoebe is correct because a college education is overly expensive and is almost a waste of money.
B. Phoebe is correct because she will not be spending tuition dollars on college while earning $140,000 during the four years it would take to earn an undergraduate degree. College graduates would never be able to make up that difference in earnings.
C. Connor is correct because it is likely that the increased income and better benefits he will earn throughout his career will outweigh the $80,000 and four years he invests in his college education.
D. Connor is correct because a person without a college degree will never be able to support himsel
Answer:
C. Connor is correct because it is likely that the increased income and better benefits he will earn throughout his career will outweigh the $80,000 and four years he invests in his college education.
