Answer:
x = -8
y = 1
Step-by-step explanation:
y = 2x + 17
x – 9y = -17
y = 2x + 17
-9y = -x - 17 (Multiply by 2)
y = 2x + 17
-18y = -2x - 34
-17y = -17
y = 1
y = 2x + 17
1 = 2x + 17
2x = 1 - 17
2x = -16
x = -8
find a possible value of b. 5x2 - bx - 8
Answer:
Step-by-step explanation:
Without more input from you, it's hard to find an exact value for b. However, b may take on a large range of values. b = 10 and b = -3 (chosen arbitrarily) are acceptable choices.
Take a look at the quadratic formula. The discriminant is b^2 - 4ac. There is nothing about this equation that restricts or forbids the use of any value of b.
what is the value of x then find the messures of Angles M and N
Answer:
x=32
Step-by-step explanation:
sum of interior angles of a triangle = 180
add up all angles and equate to 180
(4x-13)+(x+18)+15=180
5x=160
x=160/5=32
x+18 = 32+18 = 50
4x-13 = 4x32-13 = 128-13 = 115
add up all to check whether ans = 180; 15+50+115=180
step 1 solve for x step 2 after getting the value of x ,substitute and get the value of angles

Will a 11.5-inch x 18-inch rectangular tray fit in
the box shown? Explain.
Answer:
Option D
Step-by-step explanation:
From the picture attached,
In the parallelogram ABCD,
Length of diagonals AC and BD are equal.
By the property,
"If the lengths of the diagonals of a parallelogram are equal, parallelogram will be a rectangle".
Therefore ABCD is a rectangle.
That means all interior angles of the given rectangle will be 90°.
Now we apply Pythagoras theorem in right triangle ΔABC,
AC² = AB² + BC²
(22)² = (12)² + (BC)²
484 - 144 = (BC)²
BC = √340
BC = 18.44 inches
Dimensions of the given box are 12 inches by 18.44 inches.
Dimensions of the rectangular tray is 11.5 inches by 18 inches.
Since, dimensions of the box are larger than the dimensions of the tray, tray can be adjusted in the box.
Therefore, Option D will be the answer.

While studying medical treatments, scientists noticed a relationship between two of the treatments when applied together. As Treatment X became more effective, Treatment Y became less effective. Which scatter plot BEST demonstrates this relationship?
Answer: C
Step-by-step explanation: it says that As Treatment X became more effective(In the graph it shows its increases) Treatment Y became less effective. The graph shows as one is increasing other decrease.
The scatter plot C best demonstrates this relationship.
What is an inverse relation?An inverse relation is a relation in which value of two variable is inversely proportional to each other.
Given,
When treatment X became more effective, treatment Y became less effective.
Also, when treatment Y became more effective, treatment X became
less effective.
Therefore, variables X and Y follows inverse relationship.

Answer: It's the second answer. Subtract 22 from 50, then divide the result by 3.
Step-by-step explanation: 3x+22= 50. You need to subtract 22 to both sides which will become 3x=28. Then you need to divide each side by 3, and the answer is 9.3 (With 3 repeating).
Sam es siete veces más viejo que Tim. Si Sam tiene 42 años, ¿cuántos años tiene Tim?
Answer:
the tim age is 6 years
Step-by-step explanation:
The computation of the tim age is shown below:
Given that
Sam age is 42 years
And, sam would be 7 times than the tim age
Based on the above information
The tim age would be
= sam age ÷ number of times
= 42 ÷ 7
= 6 years

Step-by-step explanation:
The owner of a local movie theater keeps track of the number of tickets sold in each purchase and makes a probability distribution based on these records. Let X represent the number of tickets bought in one purchase. The distribution for X is given in the table.
A 2-column table with 5 rows. Column 1 is labeled number of tickets with entries 1, 2, 3, 4, 5. Column 2 is labeled Probability with entries 0.29, 0.44, 0.19, 0.06, 0.02.
What is the standard deviation of the distribution?
0.89
0.95
1.41
1.99
According to the discrete distribution given, the standard deviation is of 0.95.
The distribution is:
[tex]P(X = 1) = 0.29[/tex]
[tex]P(X = 2) = 0.44[/tex]
[tex]P(X = 3) = 0.19[/tex]
[tex]P(X = 4) = 0.06[/tex]
[tex]P(X = 5) = 0.02[/tex]
The expected value is given by the sum of each value multiplied by it's respective probability, hence:
[tex]E(X) = 0.29(1) + 0.44(2) + 0.19(3) + 0.06(4) + 0.02(5) = 2.08[/tex]
The standard deviation is the square root of the sum of the difference squared of each value and the mean, multiplied by it's respective probability, hence:
[tex]\sqrt{V(X)} = \sqrt{0.29(1-2.08)^2 + 0.44(2-2.08)^2 + \cdots + 0.02(5-2.08)^2} = 0.95[/tex]
The standard deviation is of 0.95.
