6 x + 11 y = 29
x + 2 y = 5
Answer:
x = 3
y = 1
Step-by-step explanation:
x= 5-2y
6x + 11y = 29
6( 5 - 2y ) + 11y = 29
30 - 12y + 11 y = 29
-y = -1
y = 1
x + 2y = 5
x = 5 - 2y
x = 5 - 2
x = 3

A state gets it money from a state lottery, a property tax, a sales tax of 5%, and an excise tax. This year it projects that it will receive $24 million from the state lottery, $32 million from the property tax, and 14 million from the excise tax. If the state needs $100 million to cover it's expenses, how many dollars worth of taxable items must be purchased in the state this year for the state to break even?
A. $600,000,000
B. $150,000,000
C. $1,500,000
D. $ 30,000,000
Answer:A
Step-by-step explanation:
The items of worth $600,000,000 should be purchased in the state to meet the requirement, the correct option is A.
What is an Equation?An equation is a mathematical statement that is formed when two algebraic expressions are equated using an equal sign.
The state has predicted to get $24 million from the state lottery,
The amount from property tax is $32 million
The amount form excise tax is $14 million
The state needs $100 million to cover its expenses
A sales tax of 5% is charged by the state
Let the total sales is $x in million dollars then the equation that can be formed is
24 + 32 +14 +(5/100 ) * x = 100
70+ (5/100 ) * x = 100
(5/100 ) * x = 100 -70
(5/100 ) * x = 30
x = 30 * 100 / 5
x = $600,000,000

Step-by-step explanation:
use the equation given
x = -11 + 7y
5x + 2y = -18
Answer:
x = -4
y = 1
(-4,1)
Step-by-step explanation:
x = -11 +7y
5x + 2y = -18
This is a Substitution problem, so you put x = -11+7y into 5x+2y = -18
5(-11 +7y)+2y = -18
5(-11) = -55
5(+7y) = 35y
-55+35y+2y = -18
Now you add 35y and 2y which gives you 37y
-55+37y = -18
Now you add +55 from -55 and -18
37y = 37
You divide each side by 37 so that y = 1
Now you plug y(1) into the equation x = -11+7y
x = -11+7(1)
-11+7 = -4
x = -4

TSolve the system of equations below by graphing. What is the solution rounded to the nearest tenth? (–1.1, 3.2) (0.2, 2.8) (0.7, –4.2) (2.7, 0.1)
Answer: Answer:The solution to the given system of equations is (2.8,0.1)
Step-by-step explanation: I got it correct on the Unit Test
Solve the inequality. Define the solution set using numbers and symbols.
[tex]\frac{x+17}{x^2 +3} \geq 4[/tex]
(x + 17) / (x ² + 3) ≥ 4
x + 17 ≥ 4 (x ² + 3)
4x ² - x - 5 ≤ 0
(4x - 5) (x + 1) ≤ 0
The left side is equal to 0 when either
4x - 5 = 0 or x + 1 = 0
x = 5/4 or x = -1
For x < -1, we have both x + 1 < 0 and 4x - 5 < 0, so their product is positive and there are no solutions to the inequality in this interval.
For -1 < x < 5/4, we have x + 1 > 0 and 4x - 5 < 0, so their product is negative.
For x > 5/4, we have both x + 1 > 0 and 4x - 5 > 0, giving a positive product and thus no additional solutions.
The solution set is then the second interval, but including the endpoints since that makes the expression on the left equal to 0:
-1 ≤ x ≤ 5/4
f(x)=-2x+4
what is x when f(x)=-8
Answer:
20
Step-by-step explanation:
f(x) = -2 (x) + 4 (substitute x for the given value)
f(x) = -2 (-8) + 4 (multiply -2 and -8)
f(x) = 16 +4 (add 16 and 4)
f = 20

A.
4m + 15 ≥ 35
B.
4m + 15 > 35
C.
4m – 15 ≥ 35
D.
4m + 15 ≤ 35
Answer:
A
Step-by-step explanation:
Inequality shows a relationship between two numbers or two expressions.
The inequality that could be used to determine the mean number of miles, m, he would need to run each day for 4 more days to achieve his goal is
15 + 4m ≥ 35
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
We have,
His goal for this week is to run a minimum of 35 miles.
So far this week, he has already run 15 miles.
The inequality that could be used to determine the mean number of miles, m, he would need to run each day for 4 more days to achieve his goal.
15 + 4m ≥ 35
4m = number of m miles run in 4 days.
Thus,
The inequality that could be used to determine the mean number of miles, m, he would need to run each day for 4 more days to achieve his goal is
15 + 4m ≥ 35

Step-by-step explanation:
It takes four workers six hours and 45 minutes to plant 24 trees. If the time it takes to plant trees varies directly with the number of trees and inversely with the number of workers, how many trees could 9 workers plant in four and a half hours?
Answer:
36 trees
Step-by-step explanation:
We are told that It takes four workers six hours and 45 minutes to plant 24 trees. Also that the time it takes to plant trees varies directly with the number of trees and inversely with the number of workers.
Thus,
t ∝ x/n
Where;
x is number of trees
n is number of workers
Now, opening the proportion symbol, we have;
t = kx/n
Where k is the constant of proportionality.
t = 6 hours 45 minutes = 6¾ hours = 6.75 hours
Plugging in the relevant values, we have;
6.75 = 24k/4
k = 4 × 6.75/24
k = 1.125
Now, we want to know how many trees could 9 workers plant in four and a half hours (4.5 hours)
Applying the same as above and Plugging in k = 1.125, we have;
4.5 = 1.125x/9
x = 9 × 4.5/1.125
x = 36 trees

After becoming sick, a patient sees a doctor who determines the most likely cause is an allergic
reaction and prescribes an antihistamine. The patient returns home and stops burning candles and
incense for the next week while taking the medication. By the end of the week, the patient is feeling
better and is telling all his friends how wonderful the medication was at relieving his symptoms. This
is an example of
1. confounding, as there is no way to tell whether it was the medication that alleviated his
symptoms
2. convenience sampling since he only stopped burning candles and incense because it was easy
3.a double-blind experiment since neither he nor the doctor really knew what was wrong
4. bias since he wanted to feel better
Answer:
I think it is 1, but I am not 100%
