f(-1)=- 2|3× -1 +5| -2 f(0)= -2|3× 0 +5| -2 f(3)= -2|3× 3 +5| -2
f= -2|-3+5|-2 f= -2|0+5| -2 f= -2|9 +5| -2
f= -2|2|-2 f= -2|5| -2 f= -2|14| -2
f= -4-2 f= -10-2 f= -28 -2

Five less than the quotient of a number and 4 is equal to – 12.
a). Translate the statement into a mathematical equation.
b). Solve the equation and show all your work. Check your answer.
Step-by-step explanation:fcvrrctygb
The statement into a mathematical equation form is given as -
(x/4 - 5) = - 12 and on solving the equation, we get x = - 28.
What is expression?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is the statement -
"Five less than the quotient of a number and 4 is equal to -12"
We can write it as equation -
(x/4 - 5) = - 12
Solving the equation, we get -
x/4 = - 12 + 5
x/4 = - 7
x = - 28
Therefore, the statement into a mathematical equation form is given as -
(x/4 - 5) = - 12 and on solving the equation, we get x = - 28.

three friends shared a basket of strawberries. Sue got 2/7 of the strawberries. Jim got 54 more strawberries than sue. Dan got 78 strawberries. How many strawberries were there in the basket.
Answer:
Step-by-step explanation:
Let x be the total no. of strawberries, Let Sue be "S", Let Jim be "J" and Dan be "D"
S = 2x/7
J = 54+S -> J = 54+(2x/7)
D = 78
J+D = 5x/7
54+(2x/7)+78 = 5x/7
132+2x/7 = 5x/7
132 = (5x/7)-(2x/7)
132 = 3x/7
132*7 = 3x
924/3 = x
x = 308.
Therefore, there were initially 308 strawberries in the basket.
Of which; Sue had two-sevenths: 88, Jim had 142 and Dan had 78
To verify our answer, add these to see if we get 308
S+J+D = 308
88 + 142 + 78 = 308

An airline company claims in a recent advertisement that more than 94% of passenger luggage that is lost is recovered and reunited with the customer within 1 day. Hunter is a graduate student studying statistics. For a research project, Hunter wants to find out whether there is convincing evidence in support of the airline company's claim. He randomly selects 315 passengers of the airline whose luggage was lost by the airline and found that 276 of those passengers were reunited with their luggage within 1 day. Are all of the conditions for this hypothesis test met, and if so, what are the null and alternative hypotheses for this hypothesis test?
Answer:
The null hypothesis is [tex]H_o : p \le 0.94[/tex]
The alternative hypothesis is [tex]H_a : p > 0.94[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 315
The population proportion is p = 0.94
The number of luggage that was recovered and reunited with the passenger in one day is k = 276
Generally the sample proportion is mathematically represented as
[tex]\r p = \frac{k}{n}[/tex]
=> [tex]\r p = \frac{276}{315}[/tex]
=> [tex]\r p = 0.876[/tex]
The null hypothesis is [tex]H_o : p \le 0.94[/tex]
The alternative hypothesis is [tex]H_a : p > 0.94[/tex]
Don claims that perpendicular lines are lines that intersect such that at least one of the angles is a right angle.
Determine whether each statement below justifies the claim. Select Yes or No for each statement
Yes No
Intersecting lines allow for the creation of four angles with a common vertex
If one of the angles is a tight angle, the angle vertical to it must also be a right angle
Because near pals are complementary the remaining two angles must also be right angles
A) Intersecting lines allow for the creation for angles with a common vertex
B) if one of the angles is a right angle, the angle the vertical to it must also be a right angle
Step-by-step explanation
C) is not true because linear pairs are supplementary not complementary because a line = 180°
B) it’s true because they are corresponding vertical angles
A) it’s true because they all have the same starting point or vertex
The statements that justifies don's claim about perpendicular lines being lines that intersect such that at least one of the angles is a right angle are; Option A; Intersecting lines allow for the creation of four angles with a common vertex.
Option B; If one of the angles is a tight angle, the angle vertical to it must also be a right angle
This is about perpendicular lines and whether they form right angles upon intersection. To answer this, let us look at the options; Option A; Yes, this statement is true because when a perpendicular line intersects another one, they will form 4 angles since they will all have the same starting point or common vertex.Option B; Yes, this statement is true because from corresponding angles theorem, we can say that they are corresponding vertical angles because they are congruent due to the transverse perpendicular line.Option C; No, this statement is not true because the angles would form linear pairs and as such since angles on a line sum up to 180°, it will also occur here and as such we can say they are supplementary angles.Read more at; brainly.com/question/18373668

Answer: second step.
Step-by-step explanation:
you then have to distribute the answer not subtract 9 1/4 from 1.5
you have to do the parenthesis next
4.5/0.5=45/5=9
then
1.5*9= 13.5
then

The point O(4,-4) would map onto itself after a reflection across the line y=-x.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
To find out which point would map onto itself after a reflection across the line y=-x, we need to reflect the given points across the line and see which one ends up in its original position.
The reflection of a point (x, y) across the line y=-x is (-y, -x).
Let's apply this formula to each given point:
The reflection of O(4,-4) across y=-x is (-(-4), -4) = (4, -4), which is same as the original point.
The reflection of O(4,0) across y=-x is (0, -4), which is not the same as the original point.
The reflection of O(0,4) across y=-x is (4, 0), which is not the same as the original point.
The reflection of O(4,4) across y=-x is (-4, -4), which is not same as the original point.
Therefore, the point O(4,-4) would map onto itself after a reflection across the line y=-x.

Find the values of a, b, and c such that the equation y=ax2+bx+c has ordered pair solutions (1,16), (−1,−2), and (0,−1). To do so, substitute each ordered pair solution into the equation. Each time, the result is an equation in three unknowns, a, b, and c. Then solve the resulting system of three linear equations in three unknowns, a, b, and c.
Answer:
c = -1
b = 9
a = 8
Step-by-step explanation:
16 = a × 1² + b × 1 + c
-2 = a × (-1)² + b × (-1) + c
-1 = a × 0² + b × 0 + c .........-> -1 = c
16 = a + b + c
-2 = a - b + c
16 = a + b - 1
-2 = a - b - 1
a + b = 17
a - b = -1 .......-> a = b - 1 ........ a = 9 - 1 = 8
(b - 1) + b = 17
2b - 1 = 17
2b = 18 .......-> b = 18/2 = 9
Answer:
y = 8x² +9x -1
Step-by-step explanation:
The coefficients of the quadratic function can be found from three points by substituting the point values into the equation and solving for the coefficients.
The equation we want to find coefficients for is ...
y = ax² +bx +c
For point (1, 16), the equation is 16 = a(1²) +b(1) +c
For point (-1, -2), the equation is -2 = a(-1)² +b(-1) +c
For point (0, -1), the equation is -1 = a(0) +b(0) +c
__
The last of these equations gives a value for c (c=-1). Substituting that into the other two gives the equations in a and b as ...
a + b = 17
a - b = -1
Adding the two equations gives ...
2a = 16 ⇒ a = 8
Subtracting the second from the first gives ...
2b = 18 ⇒ b = 9
Then the desired quadratic equation is ...
y = 8x² +9x -1

Since the war has started, you have lost 1/4 of your total body weight. If you now weigh 150 lb, how much did you weigh when the war started?
Answer:
200
Step-by-step explanation:
1/4 of 150 would be 50
If you lost 1/4 of 200
200 - 50
You would get 150
Therefore your answer is 200
Also, think of it this way, if you lost 1/4 of your body weight, 150 is 3/4 of your entire body weight- so the other 1/4 would be 50
50 x 4 = 200
1/4 = 50
2/4 = 100
3/4 = 150
4/4 = 200
