Answer:
Explanation to answers are shown in the attachment
Step-by-step explanation:
This is a long solution but the detailed step by step and appropriate mathematical manipulation has been done as shown in the attachment.
we are given two points as
(2,4) and (-2,-4)
Let's assume
first point as (x1,y1)=(2,4)
so, x1=2 and y1=4
Second point as (x2,y2)=(-2,-4)
so, x2=-2 and y2=-4
now, we can use slope formula
now, we can plug values
now, we can simplify it
so, slope is 2 ..................Answer
Answer:
now just half the first triangals answers
Step-by-step explanation:
x =21
y=24
<u>TH</u>=24 <u>PQ</u>=12
<u>RH</u>=24 <u>NQ</u>=12
<u>RT</u>=21 <u>NP</u>=10.5
>T=80 >P=80
>H=20 >Q=20
>R=80 >N=80
It would be better to buy 12 bars for 10 dollars and the rate would be $1.2. The rate for 5 bars would be $1.25.
Answer:
<h2>
y = -¹/₄x - 1</h2>
Step-by-step explanation:
If two lines are perpendicular then the product of theirs slopes is equal -1:
y=m₁x+b₁ ⊥ y=m₂x+b₂ ⇒ m₁×m₂ = -1
y = 4x - 2 ⇒ m₁=4
4×m₂ = -1 ⇒ m₂ = -¹/₄
The line y=-¹/₄x+b passes through point (4, -2) so the equation:
-2 = -¹/₄×4 + b must be true
-2 = -1 + b
b = -1
Therefore equation in slope-intercept form:
y = -¹/₄x - 1
