(5, -8) m = -3
Write an equation in point-slope form
Answers
Answer:
y + 8 = - 3(x - 5)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = - 3 and (a, b) = (5 - 8) , thus
y - (- 8) = - 3(x - 5) , that is
y + 8 = - 3(x - 5)

Step-by-step explanation;
Rounding$6.24=$6.20
$1.95=$2.00
$5.59=$6.00
So now we have done our rounding, We just have to add them together now.
($6.20+$2.00+$6.00=$14.20)
Answer:
Mindy spent around $13
Step-by-step explanation:
I just added up all the whole numbers.
But I noticed that it is ALMOST $2 for a notebook.
So, even though the sum of all the whole numbers is 12, I assumed it would be more than 12.
So Mindy spent around $13

Given the following least-squares regression line, how many seconds does this model predict a 7-foot pendulum would take to complete one period?
Answers
Answer:
the answer is the 1 with the check on it
11.2 seconds given model predicts a 7-foot pendulum that would take to complete one period.
The correct answer is option (D)
What is regression?"It is statistical model which is used to determine the relationship between variables."
What is least square method?"The least squares method is a mathematical regression analysis used to determine the line of best fit for a set of data."
Logarithm property:If log x = b, then x = (10)^b
Given : the least-squares regression line,
log Time = 0.699 + 0.500 log(Length)
We need to find the time when given model predict a 7 foot pendulum would take to complete one period.
Here, Length = 7 ft
Using given model,
⇒ log Time = 0.699 + 0.500 log(7)
⇒ log Time = 0.699 + (0.5 × 0.8451)
⇒log Time = 0.699 + 0.423
⇒ log Time = 1.122
⇒ Time = [tex]10^{1.122}[/tex]
⇒ Time = 13.2 seconds
Therefore, the correct answer is option (D) 13.2 seconds.

Ricky is inviting 8 friends to a party. If each friend will get 6 cookies and in each box are 10 cookies, how many boxes will Ricky need to get?
Answers
Answer:
5
Step-by-step explanation:
8 times 6 is 48. 5 boxes times 10 in each one is 50 cookies.
Number of boxes Ricky needs to get to a party is equals to 5 boxes.
What is word problem?
" A word problem is a mathematical problem in which we represents the real life examples with the help of mathematical operation."
According to the question,
Number of friends invited in a party = 8
Number of cookies given to each friend = 6
Total number of cookies required for 8 friends = 8 × 6
= 48 cookies
Number of cookies in each box = 10 cookies
Number of boxes for 1 cookie = 1 / 10
Number of boxes for 48 cookies = (1 / 10) × 48
= 4.8
= 5 boxes (Number of boxes cannot be
in decimals)
Hence, number of boxes Ricky needs to get to a party is equals to 5 boxes.

The equation for lines can be written as y = –6x + 2. Line t includes the point (–6, –7) and is perpendicular to line s. What is the equation of line t?
Answers
y=1/6x-6
Explanation:
What we know:
- Equation for line S: y=-6x+2
- Line T is perpendicular to line S
- Line T passes through the point (-6,-7)
To find the answer, we would need to understand two things, the first being what exactly is going on with the equation: y=-6x+2.
It’s organized in slope-intercept form, which is y=mx+b. Here’s what the variables mean:
Y=the y variable
M=the slope
X=the x variable
B=the y-intercept (the point on the line that crosses the y axis)
Knowing this, we can look at the equation for line S again: y=-6x+2. -6 is the slope of line S and 2 is the y-intercept of line S.
The second thing we need to understand is that the slope of a second line that is perpendicular to the first line is equal to the NEGATIVE RECIPROCAL of the slope of the first line.
Reciprocal: the “flip” of a fraction where the denominator and the numerator switch places
So, for example, let’s say the slope of line A=6. The slope of the line perpendicular to line A would be -1/6.
Let’s try another example: the slope of line B=-4/5. The slope of the line perpendicular to line B would be 5/4 (because two negatives makes a positive)
And here, for your question, the slope of line S=-6. Therefore, the slope of line T would be 1/6.
Awesome! We found the slope, which means so far, the equation of line T looks like this:
y=1/6x+b
All we need now is the y-intercept, which is “b” in the equation y=mx+b.
To do this, we plug in the point that the question provided us, (-6,-7), and solve. We would plug in -7 as the y variable and -6 as the x variable.
y=1/6x+b
-7=1/6(-6)+b
1) multiply 1/6 and -6
-7=-1+b
2) add 1 to both sides of the equation to isolate b
-6=b
Aha! There we have it, -6 is the y-intercept of line T.
Now, we have completed our equation:
y=1/6x-6

Answers
Answer: x=2
Step-by-step explanation:Step 1: Simplify both sides of the equation.
3−(3x−4)=2x+3(3x−7)
3+−1(3x−4)=2x+3(3x−7)(Distribute the Negative Sign)
3+−1(3x)+(−1)(−4)=2x+3(3x−7)
3+−3x+4=2x+3(3x−7)
3+−3x+4=2x+(3)(3x)+(3)(−7)(Distribute)
3+−3x+4=2x+9x+−21
(−3x)+(3+4)=(2x+9x)+(−21)(Combine Like Terms)
−3x+7=11x+−21
−3x+7=11x−21
Step 2: Subtract 11x from both sides.
−3x+7−11x=11x−21−11x
−14x+7=−21
Step 3: Subtract 7 from both sides.
−14x+7−7=−21−7
−14x=−28
Step 4: Divide both sides by -14.

write an equation of the quadratic function that has x-intercepts 5-i√2 and 5+i√2
Answers
Answer:
f(x) = x² - 10x + 27
Step-by-step explanation:
Given the x- intercepts of f(x) are x = a and x = b, then the factors are
(x - a) and (x - b) and f(x) is the product of the factors, that is
f(x) = (x - a)(x - b)
Here the x- intercepts are 5 - i[tex]\sqrt{2}[/tex] and 5 + i[tex]\sqrt{2}[/tex] , thus the factors are
(x - (5 - i[tex]\sqrt{2}[/tex] )) and (x - (5 + i[tex]\sqrt{2}[/tex] )) , that is
(x - 5 + i[tex]\sqrt{2}[/tex]) and (x - 5 - i[tex]\sqrt{2}[/tex] , then
f(x) = (x - 5 + i[tex]\sqrt{2}[/tex] )(x - 5 - i[tex]\sqrt{2}[/tex] ) ← expand using FOIL
= (x - 5)² - 2i² ← i² = - 1
= x² - 10x + 25 + 2
= x² - 10x + 27
