Answer:
x=3 y=-1
Step-by-step explanation:
substitute into one of the equations: 4x+2x-7=11
rearrange unknown terms to the left side of the equation: 4x+2x=11+7
combine like terms: 6x=18
divide both sides by x: x=18/6
calculate to product: x=3
Same thing for y:
y=2x3-7
y=6-7
y=-1
Solution:
x=3
y=-1

The table represents a linear relationship. x: −2, 0, 2, 4 y: −1, 0, 1, 2 Which of the following graphs shows this relationship?
Answer:
The second graph
Step by Step
First, note down the points given.
(-2, -1) etc
Then find the points on the graphs and see if the line of the graph goes through the point.
(-2,-1): both lines go through this point
(0,0) both lines go through this point
(2,1) only the second graph goes through this point
Therefore, the second graph is the correct answer. You can check the last point if you want to double check.

So I'm in 6th-grade accelerated class learning 7th-grade math, and our subject is More Two-Step Equations. One of the questions is 8/11(n - 10) = 64. I have to find n, but what does n equal
[tex]\dfrac{8}{11} (n-10)=64[/tex]
Distribute:
[tex](\dfrac{8}{11} )(n)+(\dfrac{8}{11} )(-10)=64[/tex]
[tex]\dfrac{8}{11} n-\dfrac{80}{11} =64[/tex]
Subtract [tex]\dfrac{80}{11}[/tex] from both sides:
[tex]\dfrac{8}{11} n-\dfrac{80}{11} +\dfrac{80}{11} =64+\dfrac{80}{11}[/tex]
[tex]\dfrac{8}{11} n=\dfrac{784}{11}[/tex]
Multiply both sides by [tex]\dfrac{11}{8}[/tex]:
[tex]\dfrac{11}{8} \times(\dfrac{8}{11} n)=\dfrac{11}{8} \times(\dfrac{784}{11} )[/tex]
[tex]\fbox{n = 98}[/tex]
Answer:
I found this. I am not sure tho!
To find the value of n in the equation 8/11(n - 10) = 64, you need to first get n by itself on one side of the equation.
To do this, you can start by isolating the n on one side by dividing both sides of the equation by 8/11. This gives you:
n - 10 = 64 * 11/8
Then, you can add 10 to both sides of the equation to get:
n = 64 * 11/8 + 10
You can then simplify this to find the value of n.
64 * 11/8 + 10 = 73
Therefore, n = 73.

The equation of a plane which passes through (2,−3,1) and is normal to the line joining the points (3,4,−1) and (2,−1,5) is given by?
Answer: We can find the equation of a plane in point-normal form, which is given by:
Ax + By + Cz + D = 0
where (A, B, C) is the normal vector to the plane and (x, y, z) are the coordinates of any point on the plane, and D is a constant.
To find the normal vector, we can use the cross product of two vectors that lie on the plane. A convenient choice for these vectors is the direction vector of the line, which is given by:
v = <2-3, -1-4, 5-(-1)> = < -1, -5, 6 >
The normal vector to the plane is given by the cross product of the direction vector of the line and the vector pointing from any point on the line to the point (2,-3,1). Let's call this vector v2 = <2-3, -3-4, 1-(-1)> = < -1, -7, 2>
So the normal vector is given by:
n = v x v2 = ( -52 + 6-7)i + (6*-1 - -12)j + (-1-7 - -5*2)k = (14)i + (-7)j + (-11)k
Given that the point (2,-3,1) lies on the plane, we can substitute these values in the point-normal form equation:
A2 + B-3 + C*1 + D = 0
-142 + -7-3 + -11*1 + D = 0
-28 - 21 - 11 + D = 0
D = 58
So the equation of the plane is :
14x - 7y - 11z + 58 = 0
This is the equation that represents the plane that passes through (2,−3,1) and is normal to the line joining the points (3,4,−1) and (2,−1,5)

write and equation in slope intercept form from points (1,1)(1,5)
Answer:
x=1
Step-by-step explanation:
By looking at the equation we can see that the x intercept stays the same, so this is a vertical slope. in slope intercept form (y=mx+b) this looks like
x=b
and since we can see the two points x is always 1, we know that b is 1 so
x=1

Like the other Hawaiian Islands, Loihi is volcanic. But unlike most of the other islands, it is still being formed. Currently, the island is more than 3,000 m high. It has about 969 m to go before it reaches sea level. If it keeps growing at its current rate, it should become visible above the surface of the ocean sometime in the next 10,000 to 100,000 years.
Question 1:
If Loihi reaches sea level in 10,000 years, what would its average rate of growth per year be?
Question 2:
What would its average rate of growth per year be if it reaches sea level in 100,000 years?
If you answer these 2 questions correctly I will give you 5 stars and thanks.
Answer:
Step-by-step explanation:
1. Since the sea level is 10,000 the average growth rate per year would be 2 mm.
2. 1000m because 10/x = 1000/100000
1000x=1000000
x=1000000/1000
x=1000
Answer:
Step-by-step explanation: 1000
A television show will be canceled if the estimated number of viewers falls below 2.5 million by Week 10.Use the graph to write an exponential function to model the situation.If this pattern continues,will the show be canceled?
Answer:No
Step-by-step explanation: Let x = Week and y = Viewers
Exponential Function: y = 2.5 million x 0.75
No, the show will not be canceled. The estimated number of viewers will remain above 2.5 million for all weeks, according to the graph.
The show will not be canceled here the estimated number of viewers will remain above 2.5 million for all weeks.
What are exponential functions?When the expression of function is such that it involves the input to be present as exponent (power) of some constant, then such function is called exponential function. There usual form is specified below. They are written in several such equivalent forms.
We are given that television show will be canceled if the estimated number of viewers falls below 2.5 million by Week 10.
Let consider that x = Week and y = Viewers
Exponential Function:
y = 2.5 million x 0.75
Here we can see that, the show will not be canceled.

11. Check for Reasonableness Nate has $50 to spend at the grocery store. He fills his shopping cart with items totaling $46. At checkout he will have to pay 6% sales tax on all items in the cart. Does he have enough money to buy everything in his cart? Explain.
Answer:
Yes, he has enough money to buy everything in his cart.
Step-by-step explanation:
If he spent $46 on groceries and has to pay a 6% sales tax, that would just be 6% of $46, and that's $2.76. 46+2.76=48.76. His total is $48.76, which is under $50.

Answer:
I think it is 180° - n.
Step-by-step explanation:
Because the one side of a rectangle is 180° and n° is on the other side of angle m°. This means that angle m° + n° should equal 180° so we have to subtract n° from 180°

The locations of each irrational number are the following:
√16 - Point a
√27 - Point b
√32 - Point c
What is Number line?Number line is a horizontal line where numbers are marked at equal intervals one after another form smaller to greater.
Since, √16 is an irrational number that is also rational,
Since, 4² = 16
Then, √ 16 must be point a.
Both √27 and √32 are greater than √25 = 5 and less than √36 = 6. Then, both are between 5 and 6.
Since, √27 < √32
Hence, √27 must be point b and √32 must be point c.
Thus, The locations of each irrational number are the following:
√16 - Point a
√27 - Point b
√32 - Point c

The LCD is 12
Step-by-step explanation:
Answer: 12
Step-by-step explanation:
= -2/3 -(-3/4)

GIVEN -5 1/3 × 4.15 determain the product
a= -22 2/15
b= 20 3/15
c= 22 2/15
d= 20 1/20
Answer: The product of -5 1/3 × 4.15 is -22 2/15.
Step-by-step explanation:
To calculate this, you can first convert the mixed number -5 1/3 to an improper fraction by multiplying the whole number part (-5) by the denominator of the fraction (3) and adding the numerator (1). This gives you -5 x 3 + 1 = -16 + 1 = -15/3.
Then you can multiply the two fractions: -15/3 × 4 15/100 = (-15/3) * (415/100) = -630/300 = -22 2/15
Therefore, the answer is a= -22 2/15.

Aha! It seems you are now working on absolute value. If you don't know what that is, I'll give you a teeny lesson. :)
|2 - 2| = 0
2 - 2 = 0
|-1 - 4| = 5
-1 - 4 = -5
|-100 - 1| = 101
-100 - 1 = -101
So basically the absolute value signs get rid of the negative number after the equation has been solved. There is no such thing as "negative" in absolute value!
The distance between H and K is 9/4. Remember, this line is flat, so you are not going to be getting any negative numbers as a result. It's absolute value.
K = 7/4, or 7/4 points away from 0.
------|--------------------------|----
K 9/4 distance H
7/4 + 9/4 = 16/4, 16/4 = 4. H = 4 :)
Let me know if you need any examples. Hope this helps!
