D) y=-2x + 6
Find the slope of the line that passes through the points. (-3, 5) and (1, 8).
Answer:
3/4
Step-by-step explanation:
To find slope, the equation is y(2)-y(1)/x(2)-x(1). So, your equation would look like: 8-5/1-(-3), which equals 3/4. Therefore, 3/4 is your answer.

Answer: 180
Step-by-step explanation:
When added together, Interior angles of a triangle are always equal to 180 degrees.
Answer:
∠FHG=120°
Step-by-step explanation:
first you calculate the angles of the triangle NGH
this is isoceles triangle, so there's 2 equal angles
and as shown, the 2 same angles are having 2 lines in each one, this 2 lines represents that the 2 angles are same
so both are 20°
any triangle has a sum of 180° of interior angles
so 180-(H+G)=the angle below N
180-(20+20)=140°
the angle below N is same as N because they're vertically opposite
140 is an exterior angle
and the exterior angle is equal to the 2 far angles
140=40+∠FHN
140-40=100°
so ∠FHN=100°
∠FHN+∠NHG=∠FHG
100+20=120°
so ∠FHG=120°

Two numbers have a difference of 13. The sum of twice one number and 3 times the other number is 1. Write a system of equations and solve the system to find the two numbers. You need not show 7 steps for this problem. Just show the system, solve the system, and write the two numbers.
Answer:
first number = 8
second number = -5
Step-by-step explanation:
Let
x = first number
y = second number
Two numbers have a difference of 13.
x - y = 13
The sum of twice one number and 3 times the other number is 1
2x + 3y = 1
x - y = 13 (1)
2x + 3y = 1. (2)
From (1)
x = 13 + y
Substitute into (2)
2x + 3y = 1.
2(13 + y) + 3y = 1
26 + 2y + 3y = 1
26 + 5y = 1
5y = 1 - 26
5y = -25
y = -25/5
y = -5
Substitute y = -5 into (1)
x - y = 13
x - (-5) = 13
x + 5 = 13
x = 13 - 5
x = 8
The obtained number is 12. And the system of equations is 2c + 4p = 40
How to solve system of equations ?Although each chicken has two legs and each pig has four legs, the total number of animal legs is:
2c + 4p = 40
Once we simplify the above equation, we get
c + 2p = 20
We also know that there are 16 animal heads in total, which can be expressed as:
c + p = 16
We can solve for "c" that use these two equations.
Once we multiply the second equation by 2, we get:
2c + 2p = 32
Once we subtract this equation from that, we get:
2p = 8
Once we solve for "p," we get:
p = 4
Substituting this "p" value into the second equation yields:
c + 4 = 16
Once we solve for "c," we get:
c = 12
As an outcome, your parents hold 12 chickens.

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 15, 30,60,... Find the 6th term.
Answer: 120, 240, 480
Step-by-step explanation:
It would appear that the numbers are increasing in multiples of 2.
15 * 2 = 30
30 * 2 = 60
The next 3 terms will therefore be:
60 * 2 = 120
120 * 2 = 240
240 * 2 = 480
Answer:
480

A man is 38 years old and his daughter is 14 years old. How
many years will it be before the man's age is just twice that of
his daughter?
ver:
years
Answer:
Step-by-step explanation
x+38=2(x+14)
The man is 38 and daughter is 14. They both will age in same years (x).
So, in how many years(x) will they both age until man is equal(=) to 2 times his daughters age?
x+ 38=2(x+14)
x+38=2x+ 28
10= x
In 10 years, the man will be 2twice as old as his daughter.

would it make more sense to buy two 10 inch pizzas or one 20 inch pizza? Explain your answer in detail.
Answer:
one 20 inch pizza
Step-by-step explanation:
radius of one 10 inch pizza is 10/2 = 5
so area of one 10 inch pizza : [tex]\pi[/tex]× [tex]5^{2}[/tex] = 25 [tex]\pi[/tex]
there are 2 ; 10 inch pizza so 25 [tex]\pi[/tex]⇒[tex]50\pi[/tex]
however 20 inch pizza radius is 10
so
[tex]10^{2}[/tex]×[tex]\pi[/tex] = 100[tex]\pi[/tex]
Use the following function rule to find f(12). f(x)=10x-4, f(12)=
f(x)=10x-4, f(12)= 116
The value of the function f(x) = 10x - 2 at f(12) is 114.
What is a function?A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
Given, A function f(x) = 10x - 4.
To find f(12) we have to replace x with 12 in the function f(x).
∴ f(12) = 10(12) - 4.
f(12) = 120 - 4.
f(12) = 114.
