[tex]y-0=\dfrac{1}{2}(x -(-2))[/tex]
Step-by-step explanation:
The point-slope form of the equation for a line with slope m through point (h, k) is ...
y -k = m(x -h)
For m = 1/2 and (h, k) = (-2, 0), the equation is ...
y - 0 = 1/2(x -(-2))

question:find the angle measure of the missing angle
if you can pls explain
Answers
Answer:
85°
Step-by-step explanation:
So in geometry, the formula to find the sum of all interior angles is denoted as follows:
n = number of sides in the polygon
( n - 2 ) × 180° = sum of the interior angles
Using that formula, a triangle has 3 sides, so
n = 3 , therefore:
= ( 3 - 2 ) × 180°
= 1 × 180°
= 180°
Since the total sum of the interior angles of a triangle all have to add up to 180°, you can create the following equation and solve:
34° + 61° + x = 180°
Solve for x.

A line passes through the points (-4, 8) and (3, -7).
Answer all parts of the question.

Part B: What is the equation of the line that passes through these points.
Part C: Where does the line intersect the x-axis and y-axis?
Answers
Answer: (hope I got them correct)
A) -15/7
B) [tex]y=-\frac{15}{7}x-\frac{4}{7}[/tex]
C) It cuts the x-axis at (-4/15,0) and the y-axis at (0,-4/7).
Step-by-step explanation:
A) Slope = [8-(-7)]/(-4-3) = -15/7
B) Let [tex]y=-\frac{15}{7}x+c[/tex] be the required equation.
Substitute x=-4, y=8.
8=(-15/7)(-4)+c
c=-4/7
The equation is therefore [tex]y=-\frac{15}{7}x-\frac{4}{7}[/tex].
C) Substitute y=0, we will get x = -4/15 i.e. it cuts the x-axis at (-4/15,0).
Substitute x=0, we will get y = -4/7 i.e. it cuts the y-axis at (0,-4/7).

Which expression is equivalent to (6-2i)(2-3i)?
Answers
Answer:
Step-by-step explanation:
(6-2i)(2-3i)=
we will use foil to multiply
-12-18i-4i+6(i^2)=
now remeber that (i^2)=-1
=12-22i-6=6-22i
Explanation: To multiply two complex numbers, use the F.O.I.L method.
So we have (6 - 2i)(2 - 3i).
So we have 12 - 18i - 4i + 6i².
Combining like terms, we have 12 - 22i + 6i².
Now, remember that i² is equal to -1 so we have
12 - 22i + 6(-1) or 12 - 22i - 6 or 6 - 22i.
So our answer is 6 - 22i.
You receive an inheritance of $15,500, and you place the full amount into a bank account. The bank pays a simple interest rate of 7.5% per year. How much interest have you earned after three years? Give your answer in dollars to the nearest dollar.
Answers
Answer:
348,750 dollars in 3 years
Step-by-step explanation:
You inheritanced 15,500 dollars. You put that into a account which has a 7.5% interest rate for one year. 15,500 x 7.5 = 116,250 a year. now you want to know how much that'll be in 3 years multiply 116,250 x 3 = 248,750.
(I'm sorry if this is incorrect i tried doing the math correctly!)
Answer:
Step-by-step explanation:
I = P x r x t
p=15500
i=7.5% must change to decimal of 0.075
t= 3 (years)
In this case
I= 15,500 X 0.075 X 3= 3,487.5
(1, 162.5 x 3)= 3487.5
Solved to nearest dollar of 3,488
A survey found that 6 out of 8 students own a pet. If there are 320 students in a school, what is a reasonable prediction for the number of students who own a pet?
Answers
Explanation:
320 ÷ 8 = 40 (40 groups of 8)
40 x 6 = 240
Answer:
Reasonable prediction = 240 students
Step-by-step explanation:
Given that:
6 out of every 8 students own a pet.
Ratio = 6 : 8
Number of students surveyed = 320
Predicted number of students who own pets = x
Ratio = x : 320
As the relationship is proportional;
6 : 8 :: x : 320
Product of mean = Product of extreme
8x = 320 * 6
8x = 1920
Dividing both sides by 8
[tex]\frac{8x}{8}=\frac{1920}{8}\\x=240[/tex]
Hence,
Reasonable prediction = 240 students

Answer:
[tex]\frac{x-5}{x+1}[/tex], [tex]x\neq -1, x\neq -9[/tex]
Step-by-step explanation:
x^2 + 4x - 45
= (x+9)(x-5)
x^2 + 10x + 9
= (x+9)(x+1)
So the fraction goes to
[tex]\frac{(x+9)(x-5)}{(x+9)(x+1)}[/tex] which is [tex]\frac{x-5}{x+1}[/tex].
Since the denominator cannot be 0, x^2 + 10x + 9 cannot be equal to 0. Therefore x cannot be -1 or -9.
