Answers
Answer:
x = 10
Step-by-step explanation:
We see and show that x = 10
This makes y = 5 and z = 7 as 5-7 (y-z) = -2
As y5-z7 = -2 then we add 10 = 8
x+y-z = 10x-2yz = 8
x-y+z = 10 -5 +7 = 12 we know x = 10
We cna now prove.
x+y-z =8
x+5y-7z = 8
x +-2yz = 8
x = 8+2yz
x= 10
And prove
(x-5y)+7z= 12
x-y =12-7z
x = 5+5y
x=10
as x-5 (=5+7z) = 12

The box plots show Lauren’s chemistry scores and her biology scores. Chemistry 2 box plots. The number line goes from 50 to 100. For chemistry, the whiskers range from 55 to 90, and the box ranges from 60 to 85. A line divides the box at 80. For biology, the whiskers range from 50 to 90, and the box ranges from 60 to 80. A line divides the box at 70. Biology Lauren used the steps below to determine the differences in the medians and the interquartile ranges. Step 1 Find the median for chemistry: 80 Find the median for biology: 70 Step 2 Find the difference in the medians: 80 minus 70 = 10 Step 3 Find the interquartile range for chemistry: 85 minus 80 = 5 Find the interquartile range for biology: 80 minus 70 = 10 Step 4 Find the difference in the interquartile ranges: 10 minus 5 = 5 Lauren determined that the difference in the medians is greater than the difference in the interquartile ranges. Which explains Lauren’s error? Lauren made her first error in step 1 because the median is 85 for chemistry and 80 for biology. Lauren made her first error in step 1 because the median is 60 for chemistry and 60 for biology. Lauren made her first error in step 3 because she should have used 90 minus 55 = 35 for chemistry and 90 minus 50 = 40 for biology. Lauren made her first error in step 3 because she should have used 85 minus 60 = 25 for chemistry and 80 minus 60 = 20 for biology.
Answers
Answer:
Lauren made her first error in step 3 because she should have used 85 minus 60 = 25 for chemistry and 80 minus 60 = 20 for biology.
Step-by-step explanation:
Lauren's box plots may have looked like those below.
Step 1
Chemistry median = 80
Biology median = 70
Correct.
Step 2
Difference in medians = 80 - 70
Correct
Step 3
Chemistry IQR = 85 - 60 = 25
Biology IQR = 80 - 60 = 20
Wrong.
This is where Lauren made the mistake.
She was finding the difference between the Max and Q3.

Answer: 19.95 x >89.95
Step-by-step explanation:
Hi, to answer this question we have to write an inequality using the information given:
The cost of each visit (x) is 19.95. That expression must be higher than the cost of the annual pass (89.95).
Mathematically speaking:
19.95 x >89.95

nanette installed a security system in her office for $150. the monthly monitoring fee is $30. so far, nanette has spent $420 for her security system. for how many months has she had the service?
Answers
Answer:
9 months.
Step-by-step explanation:
Well we subtract the one time fee of $150 from $420
420-150=270
Now we need to divide $270 by $30, the price she pays every month.
270÷30=9
She has had the service for 9 months.

Study the patterns and write down :
(a) Row 5
(b) Row n
(c) Row (n+1)
Answers
Answer:
a) Row 5: 75 - 216 - 51
b) 3n² - (n+1)³ - (71-4n)
c) 3(n+1)² - (n+2)³ - (67-4n)
Step-by-step explanation:
Column 3:
Arithmetic sequence with common difference: 63-67 = -4
an = 67 + (n-1)(-4)
an = 67 - 4n + 4
an = 71 - 4n
Row 5: 3×5² - (5+1)³ - (71-(5×4))
Row 5: 75 - 216 - 51
Row n: 3n² - (n+1)³ - (71-4n)
Row n+1: 3(n+1)² - (n+1+1)³ - 71-4(n+1)
Row n+1: 3(n+1)² - (n+2)³ - (67-4n)
Answer:
Column 1
Tn= 3n²
row n= 3n²
row n+1= 3(n+1)²
When n=5,
T₅ = 3(5)²
T₅ = 75
Thus, row 5= 75
Column 2
Tn= (n+1)³
row n= (n+1)³
row n+1
= (n+1+1)³
= (n+2)³
When n=5,
T₅ = (5+1)³
T₅ = 6³
T₅ = 216
row 5= 216
Column 3
Notice that the terms decrease by 4 with each row.
This means that there is a common difference of -4.
Common difference formula
Tn= a +d(n-1)
where a is the first term and d is the common difference.
Tn= 67 -4(n-1)
Now, simplify the formula
Tn= 67 -4n +4
Tn= 71 -4n
Row n= 71 -4n
Row n+1
= 71 -4(n+1)
= 71 -4n -4
= 67 -4n
when n=5,
T₅= 71 -4(5)
T₅= 51
Row 5= 51
Row n is the general formula for the pattern. To find the n+1 row, susbt. n+1 into n in the formula in row n.

Answers
Answer:
No real number solutions.
Step-by-step explanation:
Given a quadratic equation in standard form
ax² + bx + c = 0 ( a ≠ 0 )
The discriminant is b² - 4ac
• If b² - 4ac > 0 the equation has 2 real and distinct roots
• If b² - 4ac = 0 the equation has 2 real and equal roots
• If b² - 4ac < 0 the equation has no real roots
Given
2x² + 4x + 8 = 0 ← in standard form
with a = 2, b = 4 and c = 8, then
b² - 4ac = 4² - (4 × 2 × 8) = 16 - 64 = - 48 , thus
The equation has no real number solutions because the discriminant is < 0

Step-by-step explanation:
[tex]8^{0}[/tex] = 1, [tex]8^{\frac{1}{3} }[/tex] = [tex]\sqrt[3]{8}[/tex] = 2, [tex]8^{\frac{2}{3} }[/tex] = [tex]\sqrt[3]{8^2}[/tex] = 4, [tex]8^{1}[/tex] = 8
The series can be expressed in non exponent terms as
1 + 2 + 4 + 8 + 16 + 32 + 64 + 128 + 256 + 512 ← 10 terms
There is a common ratio r between consecutive terms, that is
r = 2 ÷ 1 = 4 ÷ 2 = 8 ÷ 4 = .... = 2
This indicates the sequence is geometric with sum to n terms
[tex]S_{n}[/tex] = [tex]\frac{a(r^{n}-1) }{r-1}[/tex]
where a is the first term and r the common ratio
Here a = 1 and r = 2, thus
[tex]S_{10}[/tex] = [tex]\frac{1(2^{10}-1) }{2-1}[/tex] = 1024 - 1 = 1023
