Answer:
3y+4x=5
Step-by-step explanation:
step 1
Find the slope
we have
(–7, 11) and (8, –9)
m=(-9-11)/(8+7)
m=-20/15
m=-4/3
step 2
Find the equation of the line into point slope form
we have
m=-4/3
point (-7,11)
substitute
y-11=-(4/3)(x+7) ----> equation of the line into point slope form
Multiply by 3 both sides
3y-33=-4(x+7)
3y-33=-4x-28
3y+4x=33-28
3y+4x=5 -----> equation of the line into standard form
Answer:
a. (2+3)×4²+1=81
b. (2+3)×(4²+1)=85
c. 2+(3×4²)+1=51
d. 2+3×(4²+1)=53
Step-by-step explanation:
a. Parentheses about the 2 + 3 - then use PEMDAS to give 5 * 16.
b Inserting 2 parentheses makes it 5 * 17 = 85.
c.Inserting the parentheses simplifies it to 2 + 48 + 1 = 51.
d. Inserting the parentheses makes it 2 + 3*17 = 53
I think is D i just had the question hope it helps
Answer:
20
Step-by-step explanation:
Order the numbers from smallest to largest, then cross one number off until you have one or two numbers left.
If there is an EVEN number of numbers(like this one): there will be two numbers left, therefore you add those two numbers together, then divide by two.
If there is an ODD number of numbers: there will be one number left, therefore that is your answer!
Hope this helps!

Given:
A rope tied from a tent pole to a stake in the ground forms 55 degrees angle with the ground.
The pole is 3 feet from the stake.
To find:
The length of the rope to the nearest tenth of a foot.
Solution:
First draw a diagram according to the given information as shown below.
We know that, in a right angled triangle,
In triangle ABC,
Therefore, the length of the rope is 5.2 foot.
