Step-by-step explanation:
1). f(x) = 2x
f(-3) = 2(-3) = -6
f(1) = 2(1) = 2
f(4) = 2(4) = 8
Ordered pairs → (-3, -6), (1, 2), (4, 8)
2). f(x) = 2x + 1
f(-3) = 2(-3) + 1 = -5
f(1) = 2(1) + 1 = 3
f(4) = 2(4) + 1 = 9
Ordered pairs → (-3, -5), (1, 3) and (4, 9)
x -3 1 4
f(x) -5 3 9
3). f(x) = -3x
f(-3) = -3(-3) = 9
f(1) = -3(1) = -3
f(4) = -3(4) = -12
Ordered pairs → (-3, 9), (1, -3), (4, -12)
x -3 1 4
f(x) 9 -3 -12

b) the fox is still from 2 seconds to 3 seconds, since the line is flat.
c) let’s look at the slope of the four intervals.
From 1 to 2, the distance increases to 4. The slope is 4/2 = 2.
From 2 to 3, the distance doesn’t change. The slope is 0.
From 3 to 5, the distance decreases to 3. The slope is -1/2.
From 5 to 6, the distance decreases to 0. The slope is -3, which is the greatest magnitude, therefore the fox is moving fastest.
A market research survey has 15 questions and will be sent to 500 people. What is the total cost to conduct the survey if it has a $1,000 base fee plus $5 per question and $2 per person surveyed?
Answers
Answer:
Total cost to conduct survey = $2075
Step-by-step explanation:
Given that:
Number of questions on survey = 15
Number of people = 500
Base fee = $1000
Per question charge = $5
Per person surveyed = $2
Let,
q be the number of questions
p be the number of people
Total cost = Base fee + 5q + 2p
Total cost = 1000 + 5(15) + 2(500)
Total cost = 1000 + 75 + 1000
Total cost = $2075
Hence,
Total cost to conduct survey = $2075

Subtract (2x - 2y) from the sum of (10x - 2y) and (-3y)
Answers
(10x-5y)-(2x-2y)= 8x-3y
ANSWER: 8x-3y
Subtract (2x - 2y) from the sum of (10x - 2y) and (-3y) is 8x -3y.
What is subtraction?Subtraction is a mathematic operation. Which is used to remove terms or objects in an expression.
The sum of (10x - 2y) and (-3y).
(10x - 2y) + (-3y),
= 10x -2y -3y
= 10x -5y
Subtract (2x - 2y) from the sum of (10x - 2y) and (-3y),
= 10x -5y - (2x - 2y)
= 8x -3y
Therefore, the expression is 8x -3y.

Answer:
Step-by-step explanation:
From the picture attached,
a). Triangle in the figure is ΔBCF
b). Since, [tex]L_1[/tex] and [tex]L_2[/tex] are the parallel lines and m is a transversal line,
m∠FBC = m∠BFG [Alternate interior angles]
Since, [tex]L_1[/tex] and [tex]L_2[/tex] are the parallel lines and n is a transversal line,
m∠BCF = m∠CFE [Alternate interior angles]
By triangle sum theorem in ΔBCF
m∠FBC + m∠BCF + m∠BFC = 180°
From the properties given above,
m∠BFG + m∠CFE + m∠BFC = 180°
m∠GFE = 180°
Therefore, angle GFE is the straight angle that will be useful in proving that the sum of the measures of the interior angles of the triangle is 180°.

Answers
Answer:
x = 13.5
Step-by-step explanation:
To find x, we use the sine rule
For the sine rule,
the ratio of the sides to the sine of the angle facing the side is equal for all the sides of the triangle
Thus,
x/sin 34 = 11/ sin 27
x = 11 sin 34/sin 27
x = 13.5
what is y=6x^2 +96x +388 in vertex form?
please show work
Answers
Answer:
y = 6(x + 8)² + 4
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Using the method of completing the square.
y = 6x² + 96x + 388
The coefficient of the x² term must be 1, so
factor out 6 from 6x² + 96x
y = 6(x² + 16x ) + 388
To complete the square
add/subtract (half the coefficient of the x- term)² to x² + 16x
y = 6(x² + 2(8)x + 64 - 64) + 388
= 6(x + 8)² - 384 + 388
y = 6(x + 8)² + 4 ← in vertex form
