Answer:
y = - 2x + 16
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (7, 2) and (x₂, y₂ ) = (2, 12)
m = [tex]\frac{12-2}{2-7}[/tex] = [tex]\frac{10}{-5}[/tex] = - 2, then
y = - 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (2, 12 )
12 = - 4 + c ⇒ c = 12 + 4 = 16
y = - 2x + 16 ← equation of line

given f(x) = 6 (1 - x) +11 what is the value of f(8)
Can someone help me out with this?
i Think all are correct not sure tho
Answer:
See below.
Step-by-step explanation:
Note: I am considering that you are supposed to think of the graph maximum point as P(x, y) = P(0, 25).
It means that the absolute maximum at x = 0, so f(0) = 25.
What is the maximum of this graph and what does it represent?
When the ball is on the ground? No, once the maximum of this graph is 25 feet and the ground is 0 feet, the statement is false.
Where the ball ended? No, the final position is h = 0 feet, not h = 25 feet.
Where the ball started? Yes, the ball was dropped in h = 25 feet.
It represents the highest point on the graph? Yes.
25 feet? Yes.
compare these amounts. use or =.

Find the perimeter of triangle QRS
helppp plzzz thx
Answer:
A. 36 cm
Step-by-step explanation:
Perimeter = SQ + RS + RQ
✔️Find SQ:
SN = SM = 10 cm (tangents drawn from an external point)
QL = QN = 2 cm (tangents drawn from an external point)
SQ = SN + NQ
SQ = 10 + 2 = 12 cm
✔️Find RS:
RS = RM + MS
RM = RL = 8 - 2 = 6 cm
MS = 10 cm (given)
Therefore,
RS = 6 + 10 = 16 cm
✔️RQ = 8 cm (given)
Thus:
Perimeter = SQ + RS + RQ
Perimeter = 12 + 16 + 8 = 36 cm

Which rule describes the composition of transformations
that maps ABCD to AB"C"D"?
O T5, -6 ory = -x(x, y)
O ry=-xoTs, – g(x, y)
O T6 -5 0 ry-axis(x, y)
O ry-axis T6, – g(x, y)
Answer:
i hope number c is correct answer
The rule which describes the composition of transformations is reflection around y axis and translation of (6, -5).
What is Geometric Transformation?Transformation of geometrical figures or points is the manipulation of a given figure to some other way.
Different types of transformations are Rotation, Reflection, Glide reflection, Translation and Dilation.
Given triangle BCD has the coordinates equal to,
B(1, 4), C(1, 2) and D(5, 3).
Let the triangle be reflected around the Y axis.
A point (x, y) after the reflection over the Y axis changes to (-x, y).
The coordinate points are,
B'(-1, 4), C'(-1, 2) and D'(-5, 3).
Now let the triangle be translated to (6, -5).
The coordinates of the triangles are,
B''(-1+6, 4-5), C''(-1+6, 2-5) and D''(-5+6, 3-5)
B''(5, -1), C''(5, -3) and D''(1, -2).
This is the exact coordinates of triangle B''C''D''.
Hence the correct transformation is reflection around y axis and translation of (6, -5).

what is equal to 18 tens
Answer:
180
Step-by-step explanation:
so if it is addition like I assume it is, you would do this:
18 +18 +18 +18 +18 +18 +18 +18 +18 +18
that is also equal to 18x10.
so 18 ten times. a simple trick for multiplying by ten is just adding a zero, so 18x10 is 180.
I THINK THIS IS RIGHT LOL
Hey there!
18 * 10
≈ 18 + 18 + 18 + 18 + 18 + 18 + 18 + 18 + 18 + 18
≈ 36 + 36 + 36 + 36 + 36
≈ 72 + 72 + 36
≈ 144 + 36
≈ 180
Therefore, the answer should be: 180

-7.4r - 6.31 = 3.23 - 5.6r
Answer:
r=−5.3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−7.4r−6.31=3.23−5.6r
−7.4r+−6.31=3.23+−5.6r
−7.4r−6.31=−5.6r+3.23
Step 2: Add 5.6r to both sides.
−7.4r−6.31+5.6r=−5.6r+3.23+5.6r
−1.8r−6.31=3.23
Step 3: Add 6.31 to both sides.
−1.8r−6.31+6.31=3.23+6.31
−1.8r=9.54
Step 4: Divide both sides by -1.8.
−1.8r/−1.8=9.54/−1.8
r=−5.3

80% of p is 20. What is p? 75% of b is 12. What is b?
Step-by-step explanation:
80% of p = 20
=> 0.8p = 20, p = 20 / 0.8 = 25.
75% of b = 12
=> 0.75b = 12, b = 12 / 0.75 = 16.
Answer:
[tex]80\% \: of \: p = 20 \\ \frac{80}{100} p = 20 \\ \frac{4}{5} p = 20 \\ p = \frac{20 \times 5}{4} \\ \boxed{p = 25}[/tex]

Two percent of the customers of a store buy cigars. Half of the customers who buy cigars buy beer. 25 percent who buy beer buy cigars. Determine the probability that a customer neither buys beer nor buys cigars.
Answer:
0.95
Step-by-step explanation:
The computation of the probability that a customer neither buys beer nor buys cigars is given below;
Given that, the probabilities are
The customers who purchased cigars be 0.02
The customers who purchased cigars + beer 0.50
And, the customers who purchased beer + cigars be 0.25
Now the probabilities where the customer purchased both
= 0.05 × 0.02
= 0.10
The probability where the customer purchased beer is
= 0.01 ÷ 0.25
= 0.04
Now the probability where a customer neither buys beer nor buys cigars is
= 1 - 0.02 + 0.04 - 0.01
= 0.95

The native bird population in a city is decreasing at a rate of 10% per year after 1 year the population of native birds is 14000 complete the recursive defined function to describe the situation.
The recursively defined function that describes the given situation would be f(n) = f(n-1) x 0.9, after four years, 9185 birds will be remaining.
What is a function?A function is defined as a relation between the set of inputs having exactly one output each.
The native bird population in a city is decreasing at a rate of 10% per year after 1 year the population of native birds is 14000.
f(0) = 14000
f(n) = f(n-1) x 0.9
f(1) = f(0) x 0.9
= 14000 x 0.9
= 12600
f(2) = f(1) x 0.9
= 12600 x 0.9
= 11340
f(3) = f(2) x 0.9
= 11340 x 0.9
= 10206
f(4) = f(3) x 0.9
= 10206 x 0.9
= 9185.4
Therefore, after four years, 9185 birds will be remaining.
