Answer:
no solution
Step-by-step explanation:
2x + 8y = 4
x = -4y - 2
Divide both sides of the first equation by 2.
x + 4y = 2
x = -4y - 2
Substitute -4y - 2 for x in the first equation.
-4y - 2 + 4y = 2
0 - 2 = 2
0 = 4
Since after doing legal steps, we get a false statement, 0 = 4, that means there is no solution.

5) Add using Place-Value diagrams: 215 six + 43 six
As I understand, we want to perform the given sum by adding the correspondent place values.
Using this method, we will see that the value of the sum is 258.
First, we define the place values as the value that each "position" has, where the reference is the decimal point.
The first place at the left of the decimal points is the units digit.
The second is the tens digit, and so on.
With this, we can rewrite te twi given numbers as:
215 = 2*100 + 1*10 + 5*143 = 4*10 + 3*1Then the sum can be done as:
215 + 43
(2*100 + 1*10 + 5*1) + ( 4*10 + 3*1)
2*100 + (1 + 4)*10 + (5 + 3)*1
2*100 + 5*10 + 8*1 = 258
Then we have:
215 + 43 = 258

If you solve an equation by graphing each side separately, which of these is the solution to the equation?
A. the x-coordinate of the intersection point
B. the y-coordinate of the intersection point
C. both the x- and the y-coordinates of the intersection point
D. There is only a solution if the lines are identical.
9514 1404 393
Answer:
A. the x-coordinate of the intersection point
Step-by-step explanation:
If you are solving ...
f(x) = g(x)
the solution is one or more values of x. That is still true if you rewrite the equation to be a system of equations ...
y = f(x)
y = g(x)
The value of y tells you the value of each side of the original equation where the solution causes the functions to be equal. That is largely irrelevant. What you're looking for is the value of x.
The solution is the x-coordinate of the intersection point.

Answer:
2 4/9
Step-by-step explanation:
1. To change an improper fraction to a mixed number, divide the numerator by the denominator. Then, write down the quotient as the whole number and the remainder (left over amount) as the numerator. Remember to NOT change the denominator.
2. Given the information above:
22 ÷ 9 = 2 R 4 2 4/9Therefore, 22/9 as a mixed number is 2 4/9.

a positive real number is 4 less than anther of the sum of the squares of the two numbers is 72 then find the numbers.
Answer:
3.657 and 7.657 to the nearest thousandth.
Step-by-step explanation:
x - y = 4
x^2 + y^2 = 72
From equation 1
x = y + 4 so
(y + 4)^2 + y^2 = 72
y^2 + 8y + 16 + y^2 - 72 = 0
2y^2 + 8y - 56 = 0
y^2 + 4y - 28 = 0
y = 3.657.
so x = 7.657.

of all the trees planted last year by a landscaping firm, only 1 in 10 trees died within a month. suppose a new landscaping firm is hired to plant 15 new trees. Let X denote the number of trees planted out of the 15 that died.
What is the lowest value of X that is consistent with the belief that the tree died due to mishandling?
The number of trees that died is an illustration of proportions.
The lowest value of X that is consistent with the belief that the tree died due to mishandling is 1.5
From the question, we have: 1 out of 10 died
This means that, the mean number of trees that died are:
[tex]\mathbf{\bar x =\frac{1}{10}}[/tex]
In 15 trees, the number (n) of trees expected to die is:
[tex]\mathbf{n = \bar x \times 15}[/tex]
So, we have:
[tex]\mathbf{n = \frac{1}{10} \times 15}[/tex]
[tex]\mathbf{n = 1.5}[/tex]
Hence, the lowest value of X is 1.5

You may actually start by finding a pattern you like, then figuring the material required to construct the pattern, then working backward to determine the dimensions you need to use to stay within your material budget. You will probably draw a diagram at many points in the planning process.
You deposit $200 in a savings
account that pays a simple
interest rate of 3.25% per year.
How much interest will you earn
after 5 years?
Answer:
$32.50
Step-by-step explanation:
The equation for simple interest is
Simple Interest=P×r×n
where:
P=Principal amount
r=Annual interest rate
n=Term of loan, in years
so
P=200
r=0.0325
n=5
so 200*0.0325*5=32.5

Step-by-step explanation:
Jessie recently drove to visit her parents who live 570 miles away. On her way there her average speed was 25 miles per hour faster than on her way home (she ran into some bad weather). If Jessie spent a total of 19 hours driving, find the two rates (in mph). Round your answer to two decimal places, if needed.
Jessie's average speed to her parents' house: ___________ mph
Jessie's average speed from her parents' house: ___________ mph
Answer:
Step-by-step explanation:
Let v be her average speed from her parents house
Let t₁ be the time traveled to parents house
Let t₂ be the time traveled from parents house
t₁ + t₂ = 19
t₁ = 19 - t₂
as the distance does not change, we can equate two velocity•time statements
vt₂ = (v + 25)t₁
vt₂ = (v + 25)(19 - t₂)
vt₂ = 19v - vt₂ + 475 - 25t₂
2vt₂ = 19v + 475 - 25t₂
vt₂ = 570 and t₂ = 570/v
2(570) = 19v + 475 - 25(570/v)
1140 = 19v + 475 - 14,250/v
665 = 19v - 14,250/v
665v = 19v² - 14250
0 = 19v² - 665v - 14250
0 = v² - 35v - 750
quadratic formula
v = (35 ±√(35² - 4(1)(-750))) / 2
v = (35 ± 65) / 2
v = - 15 mph which we ignore as she did not spend hours driving backwards
or
v = 50 mph is average speed from parents house
v + 25 = 75 mph is average speed to parents house.
the trip to took 570/75 = 7.6 hrs
the trip from took 570/50 = 11.4 hrs. total of 19 hrs.
Perpendicular to y=-3x+11 and goes through the point (-9,-6)
please help it’s due next period
Answer:
y = 1/3x - 3
Step-by-step explanation:
If the line is perpendicular to y = -3x + 11, it means that the two gradients multiply to make -1.
So the gradient of the perpendicular line is 1/3 (-3 × 1/3 = -1)
y = 1/3x + c
Next, substitute x = -9, and y = -6 to find the y intercept, or c:
-6 = 1/3(-9) + c
-6 = -3 + c
c = -6 + 3
c = -3
The equation of the line is y = 1/3x - 3

Answer:

Step-by-step explanation:
Judging by the answers, the lines have slopes of 7/3 and 2/5. (We could verify this by close examination of the graph.) The shading is above (greater than) the line with the smaller slope value (2/5), and below (less than) the line with the steeper slope value (7/3).
That means we're looking for a pair of inequalities with the symbols ...
