Answer:
y=2/3x-4
Step-by-step explanation:
Answer:
Option d. 
Step-by-step explanation:
we know that
If a ordered pair is a solution of an inequality, then the ordered pair must be satisfy the inequality
Verify each case
case a) 
we have

Substitute the value of x and the value of y in the inequality and then compare the results

-----> is not true
therefore
the ordered pair is not a solution
case b) 
we have

Substitute the value of x and the value of y in the inequality and then compare the results

-----> is not true
therefore
the ordered pair is not a solution
case c) 
we have

Substitute the value of x and the value of y in the inequality and then compare the results

-----> is not true
therefore
the ordered pair is not a solution
case d) 
we have

Substitute the value of x and the value of y in the inequality and then compare the results

-----> is true
therefore
the ordered pair is a solution
Answer:
missing side: 133 cm
Explanation:
Provided <u>2 length sides</u> and <u>one angle</u> also need to find <u>one missing side</u>.
So, use cosine rule:
⇒ a² = b² + c² - 2bc cos(A)
<u>Insert values</u>
⇒ g² = 166² + 147² - 2(166)(147) cos(50)
⇒ g² = 17794.3935
⇒ g = √17794.3935
⇒ g = 133.3956
⇒ g = 133 (rounded to nearest whole number)
Answer:
120 ft
Step-by-step explanation:
A slope of 12/100 means for every 12 units of distance you move horizontally you descend by 100 of the same units vertically. Assuming now that the slope does not change, i.e it remains constant throughout your trip; descending by 1000 ft should mean you have moved horizontally by 120 ft so that the slope is maintained.
x/1000 = 12/100
x = 120 ft
Answer:
Helen: 60mph and Anne: 50mph
Step-by-step explanation:
3.2r+2.8(r-10)=332 is the equation that we use, given the information we have.
We distribute and combine like terms and add 28 to both sides and divide by 6.
3.2r+2.8(r-10)=332
3.2r+2.8r-28=332
6r=360
6r/6=360/6
r=60 So, Helen's speed is 60mph.
Next, we'll solve Anne's speed.
r-10=50
60-10=50 So, Anne's speed is 50mph.
