The equation of the perpendicular line is y = -7/2(x + 5) + 2
How to determine the perpendicular line equation?From the question, we have the following parameters that can be used in our computation:
y=2/7x-8
Also, from the question;
We have the following points
Point = (-4, 2) i.e. (x, y) = (-4, 2)
The equation of a line can be represented as
y = mx + c
Where
Slope = m
By comparing the equations, we have the following
m = 2/7
This means that the slope is 2/7
The slopes of perpendicular lines are opposite reciprocals
This means that the slope of the other line is -7/2
The equation of the line is then calculated as
y = m(x - x₁) +y₁
Where
m = -7/2
(x₁, y₁) = (-4, 2)
So, we have
y = -7/2(x + 5) + 2
Hence, the line has an equation of y = -7/2(x + 5) + 2

help me pls kinda stuck lol
Answer:
see explanation
Step-by-step explanation:
(a)
To find the x- intercepts , let y = 0 , that is
6x - x² = 0 ← factor out x from each term
x(6 - x) = 0
Equate each factor to zero and solve for x
x = 0
6 - x = 0 ⇒ x = 6
Coordinates of P (6, 0 )
(b)
The axis of symmetry is a vertical line, positioned at the midpoint of the zeros
x = [tex]\frac{0+6}{2}[/tex] = [tex]\frac{6}{2}[/tex] = 3
Equation of axis of symmetry is x = 3
(c)
Given a parabola in standard form y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
y = 6x - x² = - x² + 6x ← is in standard form
with a = - 1, b = 6 , then
[tex]x_{vertex}[/tex] = - [tex]\frac{6}{-2}[/tex] = 3
Substitute x = 3 into y = 6x - x² for y- coordinate
y = 6(3) - 3² = 18 - 9 = 9
coordinates of maximum point = (3, 9 )

Which situations can be represented by an exponential function?
Select each correct answer.
Every year, the number of online video subscriptions increases by 3 times what is was the previous year.
In a structure made of bricks, each row has 10 more bricks than the previous row.
The value of a vehicle decreases by 11% each year.
A dentist's office accepts 15 new patients each month.
9514 1404 393
Answer:
(a) subscriptions
(c) vehicle value
Step-by-step explanation:
Exponential functions are used to describe situations where the amount of change is proportional to the amount.
If the amount of change is a constant, then the function is linear.
A. video subscribers change by an amount proportional to their number, so is an exponential function.
B. the change in number of bricks in a row is a constant, so the function is a linear function.
C. The amount of change is proportional to the value, so the function is an exponential function.
D. The change in patient count is a constant, so the function is a linear function.

Answer:
FD = 8
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{FD}{BA}[/tex] = [tex]\frac{FE}{BC}[/tex] , substitute values
[tex]\frac{x+3}{2x+2}[/tex] = [tex]\frac{16}{24}[/tex] = [tex]\frac{2}{3}[/tex] ( cross- multiply )
2(2x + 2) = 3(x + 3) ← distribute parenthesis on both sides
4x + 4 = 3x + 9 ( subtract 3x from both sides )
x + 4 = 9 ( subtract 4 from both sides )
x = 5
Thus
FD = x + 3 = 5 + 3 = 8

step 1. why are you in a hurry?
step 2. a binomial that is a common factor of 121 - 25x^2 and 25x^2 + 55x + 121.
step 3. the factors. of 121 - 25x^2 are (11 - 5x)(11 + 5x).
step 4. the factors of 25x^2 + 55x + 121 are (5x + 11)(5x + 11).
step 5. the common factor is 5x + 11.
gradient of line 6x+2y+9=0
Answer:
gradient = - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c( m is the slope (gradient) and c the y- intercept )
Given
6x + 2y + 9 = 0 ( subtract 6x + 9 from both sides )
2y = - 6x - 9 ( divide the 3 terms by 2 )
y = - 3x - [tex]\frac{9}{2}[/tex] ← in slope- intercept form
with gradient m = - 3

What is the area of the composite figure? 65 cm2
40 cm2
52.5 cm2
60 cm2
Area of the composite figure will be 52.5 cm².
Area of the composite figure,Divide the figure into small parts of different shapes.Add the areas of the divided figures.
Given composite figure is divided into two parts (1) triangle ABC (2) Rectangle DEFG
Area of ΔABC = [tex]\frac{1}{2}(AB)(BC)[/tex]
= [tex]\frac{1}{2}(5)[8-(1+2)][/tex]
= [tex]\frac{1}{2}(5)(5)[/tex]
= 12.5 cm²
Area of rectangle DEFG = Length × Width
= 8 × 5
= 40 cm²
Area of the composite figure = Area of triangle ABC + Area of DEFG
= 12.5 + 40
= 52.5 cm²
Therefore, area of the composite figure will be 52.5 cm².

-10x+y=-22 -8x+y=-18 solve by elimination
Answer:
x=2, y= -2
Step-by-step explanation:
Answer:
-10x+y=-22---------equation 1
-8x+y=-18----------equation 2
subtract eqn 1 and 2
-10x+y=-22
-8x+y=-18
(+) (-) (+)
__________
-2x=-4
or, x=2
put the value of x in equation 1 we get
-10×2+y=-22
y=-22+20
or, y = -2
therefore x=2 and y=-2 ans.
A motorcyclist traveled at a rate of 60 miles per hour for 3 hours, then took a break for lunch for 45 minutes. She then traveled for another amount of time at 60 miles per hour before reaching her destination. If she traveled a total of 270 miles, and left at 9:30 a.m., at what time did she arrive at her destination?
Please help:( need this ASP
Answer:
2:45 p.m.
Step-by-step explanation:
60 miles per hour for 3 hours
time: 12:30
miles driven: 180
45 minutes for lunch
time: 1:15
miles driven: 180
60 miles an hour till she hits 270
270-180=90
90 miles = 1.5 hours of driving
1.5 hours plus 1:15 = 2:45

In ΔIJK, i = 74 inches, j = 23 inches and ∠K=20°. Find the area of ΔIJK, to the nearest square inch.
Answer:
291in^2
Step-by-step explanation:
Using the formula
Area of the triangle = 1/2absin theta
A = 1/2ijsin<K
Given
i = 74in
j = 23in
<K = 20 degrees
Area = 1/2 * 74*23sin20
Area = 37*23sin20
Area = 852sin20
Area = 291.059in^2
Hence the area of the triangle to nearest square inch is 291in^2
