Answer:
x + y = 14
Step-by-step explanation:
Parallel lines have the same slope, so the line's slope will be -1.
Plug this slope and the given point into y = mx + b to find b:
y = mx + b
4 = -1(10) + b
4 = -10 + b
14 = b
Then, plug this and the slope into y = mx + b
y = -x + 14
Then, put this into standard form by moving the x to the other side:
x + y = 14 is the equation in standard form
Answer:
See below.
Step-by-step explanation:
So, we have:
PART A:
Find the GCF. Notice that we have a 3 in every term and a p in every term. Thus, the GCF is 3p:
This is the most we can do.
PART B:
Continue from where we left off. Factor the entire expression:
Answer: -16
Step-by-step explanation:
Let the number be y
Four times a number minus twenty-one can be written as:
(4 × y) - 21 = 4y - 21
Six times the number plus eleven can be written as:
(6 × y) + 11 = 6y + 11
Combining both equations will give:
4y - 21 = 6y + 11
4y - 6y = 11 + 21
-2y = 32
y = 32/-2
y = -16
The number is -16
Answer:
BC = 10.24
Step-by-step explanation:
You can use the Pythagoras theorem for this question
+ 
= 
a = 8cm
b = ???
c = 13cm
We will solve for B (length BC)
+ =
+ = 
Rearrange for b
= -
= 105
b = 
b = 10.24
Answer: True
Step-by-step explanation:
This is true because for a square, all angles and sides are equal. That is no side has a longer length than the other. The diagonals of a square are therefore perpendicular bisectors of each other.
