Answer:
y = (-1/2)x + 21/2
Step-by-step explanation:
Given equation:
y - 2x + 7
Coordinates = (5,8)
Find:
Perpendicular equation
Computation:
y = mx + c
y - 2x + 7
y = 2x - 7
So,
m = 2
The negative reciprocal of 2 is -1/2
So,
For,
Coordinates = (5,8)
y = mx + c
8 = (-1/2)(5) + c
8 = -5/2 + c
c = 8 + 5/2
c = 21 /2
So,
y = mx + c
y = (-1/2)x + 21/2
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Starting temperature = - 5°F
Temperature at midday =increase in temperature by 78°F = (starting temperature + 78°F)
Temperature at nightfall = decrease in temperature by 32°F = ( temperature at midday - 32°F)
Temperature at midday:
(-5°F + 78°F) = 73°F
Temperature at nightfall:
(Temperature at midday - 32°F)
(73°F - 32°F) = 41°F
the answer is (f/g)(x) = 2(x^2 - 7) + 1
= 2x^2 - 14 + 1
= 2x^2 - 13

Explanation:
Theorems about triangles identify relationships that can be used to formulate equations that can be used in the problem-solving process.
The idea with problem solving is to start with what you know, and make use of the relationships between that and what you don't know in order to find a solution.
