Answer:
y = -6x - 16Step-by-step explanation:
The point-slope form of the equation is y - y₀ = m(x - x₀), where (x₀, y₀) is any point the line passes through and m is the slope:
m = -6
(-3, 2) ⇒ x₀ = -3, y₀ = 2
The point-slope form of the equation:
y - 2 = -6(x + 3)
So:
y - 2 = -6x - 18 {add 2 to both sides}
y = -6x - 16 ← the slope-intercept form of the equation

What is Box- plot?An illustration of variation in a set of data is called a box and whisker plot. A histogram analysis usually gives an adequate display, but a box and whisker plot can add more detail while enabling the display of different sets of data on the same graph.
Given:
According to the box plot.
Restaurant A serves 22 to 47 ranges
and, Restaurant B serves 28- 42 ranges.
Hence, Restaurant A serves better.

The expression 200 - 16t2 models the height in feet of an object that falls from the initial height of 200 feet t seconds after being dropped. Find the height of the object after 0.75 seconds. Make sure and include the units of feet in your answer for full credit. Round your answer to the nearest hundredth place.
Answer:
Concept: Modeling expressions
We are given the equation [tex]200 - 16 {t}^{2} [/tex]We want to find the time after 0.75 seconds given that t is represented in seconds.Hence we do [tex]200 - 16(0.75)^{2} [/tex]Hence we get the answer to 191 feetThe height of the object that falls after 0.75 seconds given that t is represented in seconds is 191 feet.
What is a quadratic equation?A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
The expression 200 - 16t^2 models the height in feet of an object that falls from the initial height of 200 feet t seconds after being dropped.
We need to find the time after 0.75 seconds given that t is represented in seconds.
The expression is given
[tex]200 - 16t^2[/tex]
time t = 0.75
Substitute the value of t in the given expression
= 200 - 16(0.75)^2
= 200 - 9
= 191
Hence we get the answer to 191 feet.

Determine whether the lines, 2x – y = 7 and y = – 1/2x – 10 are parallel or perpendicular . Explain the reason for your answer.
Answer:
perpendicular
Step-by-step explanation:
a line is perpendicular to another line when m of one line is the negative or opposite reciprocal of the other. m= 2
the perpendicular lines for that would be 1/2 which is the reciprocal and then the opposite sign which is negative.

Look at this set of ordered pairs:
(3, -13)
(3, 2)
(18,-5)
Is this relation a function?
yes
no
Answer:
NoStep-by-step explanation:
Given ordered pairs:
(3, -13) (3, 2) (18,-5)There is a repeat of domains (3) with different range (-13 and 2) but the function can't have repeat domains so it is not a function
Answer:
It would not be a function
Step-by-step explanation:
A function has no repeating 'x' values
(3,-13) x=3
(3,2) x=3
(18,-5) x=18
So, because there is more than one of the same 'x' value (3) it is not a function.

The volume V of a pyramid varies jointly as the
area of the base B and the height h, and
V = 24 ft3 when B = 12 ft2 and h = 6 ft. Find B
when V = 54 ft3 and h = 9 ft.
Answer:
18ft²
Step-by-step explanation:
V volume pyramid = 1/3× base area × height
V = 1/3 × B × h
24 ft³ = 1/3(12ft²)(6ft)
when V =54 ft³ h= 9ft B =?
V=1/3Bh
B=V3/h
B=(54×3)/9
B=6×3
B=18 ft²

Answer:
Yes
3
Step-by-step explanation:
a direct variation is written in the form
y = kx
k is a constant which is usually non zero.
6y = k18x
k = 3
An increase in x would lead to an increase in y
