write a linear function f with the values f(-2)=8 and f(1)=-10
Answer:
The linear function f(x) = -6x - 4
Step-by-step explanation:
The equation of the linear function f(x) is y = m x + b, where
y = f(x)m is the slope of the line represents the functionb is the y-intercept ⇒ value y at x = 0The rule of the slope is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where
(x1, y1) and (x2, y2) are two points on the line∵ f(x) = y ⇒ is the function of the set of ordered pairs (x, y)
∴ f(-2) = 8 is the point (-2, 8)
∴ f(1) = -10 is the point (1, -10)
∴ x1 = -2 and y1 = 8
∴ x2 = 1 and y2 = -10
→ Substitute them in the rule of the slope to find it
∵ m = [tex]\frac{-10-8}{1--2}[/tex] = [tex]\frac{-18}{1+2}[/tex] = [tex]\frac{-18}{3}[/tex]
∴ m = -6
→ Substitute it in the form of the equation above
∵ y = -6(x) + b
∴ y = -6x + b
→ To find b substitute x by 1 and y by -10
∵ x = 1, y = -10
∴ -10 = -6(1) + b
∴ -10 = -6 + b
→ Add 6 to both sides
∵ -10 + 6 = -6 + 6 + b
∴ -4 = b
∴ b = -4
→ Substitute it in the equation
∴ y = -6x + -4
∴ y = -6x - 4
∵ y = f(x)
∴ The linear function f(x) = -6x - 4

Feliks joins a local recreation center to play basketball the reception charges $20 annual fee plus additional $15 per month for the usage of the basketball courts Feliks prepays by writing a check for 3185 for how many months did he prepays for
Answer:
211 months
Step-by-step explanation:
Feliks joins a local recreation center to play basketball the reception charges $20 annual fee plus additional $15 per month for the usage of the basketball courts Feliks prepays by writing a check for 3185 for how many months did he prepays for
Let the number of months that he prepays for be represented by m
Hence, we have the equation
$20 + $15 × m = $3185
Hence:
20 + 15m = 3185
Collect like terms
15m = 3185 - 20
15m = 3165
m = 3165/15
m = 211 months

Drake needs to drill holes in a wooden plank. The holes will have a diameter of 0.5 millimeters, with an error allowance of 0.05 millimeters. Which equation can be used to find the minimum and maximum acceptable diameters?
Answer:
|x − 0.5| = 0.05
Step-by-step explanation:
Here x represents the diameter,
Since, an error of 0.05 millimeters is allowance in diameter,
Thus, the maximum acceptable diameter = x + 0.05,
And, the minimum acceptable diameter = x - 0.05
According to the question,
The holes will have a diameter of 0.5 millimeters,
Thus, x - 0.05 < 0.5 and 0.5 < x + 0.05
⇒ x - 0.5 < 0.05 and x - 0.5 > - 0.05
⇒ x - 0.5 < 0.05 and -(x -0.5) < 0.05
⇒ |x-0.5| < 0.05
⇒ Option D is correct.

Michelle ordered shirts to sell at the school carnival. She paid $2.80 per shirt, she adds a
150% markup to the total price she paid for the shirts.
What is the selling price of each shirt?
PLEASE HELP!! Any help will be greatly appreciated!
Answer:
The selling price is $7
Step-by-step explanation:
Step one:
Given information
She paid $2.80 per shirt
She adds a 150% markup to the total price she paid for the shirts
Let us find 150% of $2.80
=150/100*2.8
=1.5*2.8
=$4.2
Hence the selling price is the markup price plus the cost price
=4.2+2.8
=$7
2x+7y=3
X= -4y
X=?
Y=?
Answer:
x=12, y=-3
Step-by-step explanation:
Plug (-4y) in for x in the top equation. The equation will now read 2(-4y) + 7y = 3. Distribute the 2 into the perenthecies getting: -8y+7y=3. -8+7 is -1 giving -y+3. Divide by -1 making y = -3. Plug -3 back into the top equation and solve for x: 2x + 7(-3)=3. 2x-21=3. 2x=24. x=12.
what method is this?
When graphing on the complex plane , which quadrant will the complex number 10 - 13i be found in ?
Answer:
The complex number would be in the 4th quadrant.
Step-by-step explanation:
We know that a complex number is a number that can be expressed in the form of a + bi,
where
'[tex]a[/tex]' and b are real numbers, and '[tex]i[/tex] represents the imaginary unitGiven the complex number
10 - 13i
Here,
Coefficient of the real part of the complex number = 10Coefficient of the imaginary part of complex number = -13As the coefficient of the imaginary part holds a negative sign, and the real part holds a positive sign.
Thus, the complex number would be in the 4th quadrant.
Does anyone know how to do this?
Answer:
y= Ix-3I (that says absolute value btw)
Step-by-step explanation:
This is the result of starting with y = |x|, then shifting it three units to the right. Replacing x with x-3 moves the xy axis three units to the left, giving the illusion the V shaped curve moved 3 spots to the right.
We don't shift up or down since the vertex is on the x axis.
We also don't vertically compress or stretch the graph either.
Side note: the vertex for this graph is (3,0) which is the lowest point of the curve.
A banks loan officer writes applications for credit the ratings are normally distributed with a mean of 200 and a standard deviation of 50 fine P 60 the score which separates the lower 60% from the top 40% round to 1 Decimal Pl.
Answer:
212.7
Step-by-step explanation:
Calculation to Find P60 the score which separates the lower 60% from the top 40%
First step is to find z of 60% using the invNorm distribution
Hence,
z=0.6=0.2533
Now let Find P60 which is the score which separates the lower 60% from the top 40% using this formula
x<=>z
Where,
Standard deviation=50
Mean=200
z=0.2533
Let plug in the formula
x=0.2533*50+200
x=12.665+200
x=212.665
x=212.7(Approximately)
Therefore the score which separates the lower 60% from the top 40% is 212.7

The ratio of the number of red cards to the number of black cards in a deck is 3:10
2 more cards are added to the deck.
The ratio of red to black cards in the deck is now 1:3
How many black cards are in the deck?
Answer:
Then the black cards=12
Step-by-step explanation:
N of red=3
N of black=10
and we have ratio 3:10
think when we ⇒ add 2 to red, will be 5:10= 1:2 not equal to 1:3
⇒add 1 to red and 1 to black, the ratio will be 4:11 not equal to 1:3
⇒add 2 to black, the ratio will be 3:12 = 1:3
Then the black cards=12
hope this helps!
Answer:
Either
(1) there were originally 60 black cards, and 2 red cards were added, or
(2) there were originally 20 black cards, and 1 red card and 1 black card were added.
Step-by-step explanation:
The ratio of red cards to black cards is 3:10.
Since we don't know the actual numbers of red and black cards, we can write the ratio of red to black cards as
3k/10k
After adding 2 cards, the ratio of red cards to black cards becomes 1:3.
There are 3 ways of adding 2 cards: (A) both red, (B) 1 red and one black, (C) both black.
Possibility A: add two red cards
(3k + 2)/(10k) = 1/3
10k = 9k + 6
k = 6
3k/10k = 3(6) / 10(6) = 18/60
There were originally 60 black cards.
Possibility B: add 1 red card and 1 black card
(3k + 1)/(10k + 1) = 1/3
10k + 1 = 9k + 3
k = 2
3k/10k = 3(2) / 10(2) = 6/20
There were originally 20 black cards.
Possibility C: add two black cards.
(3k)/(10k + 2) = 1/3
10k + 2 = 9k
k = -2
3k/10k = 3(-2) / 10(-2) = -6 / -20
We cannot have a negative number of cards.
No solution.
Answer: Either there were originally 60 black cards, and 2 red cards were added, or there were originally 20 black cards, and 1 red card and 1 black card were added.

A group of 5 friends want to buy a flat-screen TV for $210. The tax comes to $15. Write and solve a multiplication equation to find how much money each person should pay if each person pays the same amount.
Answer:
$45
Step-by-step explanation:
In order to create a multiplication equation, we would need to use a single variable that represents the amount that each friend will pay. This can be represented by the variable x. We multiply this variable by the number of friends which should equal the total of the TV with the tax included. Like so...
$210 + $15 = 5x
Now that we have the equation we can go ahead and solve it by adding the total and the tax, and then dividing both sides by 5 in order to isolate x.
$210 + $15 = 5x
$225 = 5x
$45 = x
Finally, we can see that each friend will pay the same amount which is $45

One side of a triangle is twice as long as a second side. The remaining side is 3 larger than the second side. The perimeter is 39m. Find the length of each side.
Answer:
Lengths all the three sides are 9m, 18m and 12m
Step-by-step explanation:
Let us assume the length of the second side to be x m
According to the question:
first side = 2x
third side = x + 3
Applying the formula of perimeter:
Perimeter = length + breadth + height
39 = 2x + x + (x + 3)
39 = 2x + x + x + 3
39 = 4x + 3
39 - 3 = 4x
4x = 36
x = [tex]\frac{36}{4}[/tex]
x = 9
length of the first side (x) = 9 m
length of the second side (2x) =2 × 9 =18 m
length of the third side (x + 3) = 9 + 3 = 12 m
∴ lengths all the three sides are 9m, 18m and 12m
