(1,-2)(5,4) find the mid point
Answer:
Step-by-step explanation:
Given points A ( 1 , - 2) and B ( 5 , 4)
Mid point of AB is
= ( ( x1 +x2)/ 2 , ( y1+ y2)/ 2 )
= ( ( 1 + 5)/2 , ( - 2 + 4)/2 )
= ( 3 , 1 )

Determine the coordinates of the y-intercept of 3x − 4y = 24.
Answer:
(0, -6)
Step-by-step explanation:
At the y-intercept, the x-coordinate equals zero.
3x - 4y = 24
3(0) - 4y = 24
-4y = 24
y = -6
Answer: (0, -6)
Put the following equation of a line into slope-intercept form, simplifying all fractions. y - 3x = -1
Answer:
y=3x-1
Step-by-step explanation:
y-3x=-1
y-3x+3x=-1+3x
y=3x-1
Answer:
y=3x-1
Step-by-step explanation:
y-3x=-1
y=3x+(-1)
y=3x-1

Answer:
Neither
Step-by-step explanation:
y - 4 = 7(x - 6)
y - 4 = 7x - 6
+4 +4
y = 7x - 2
______________
y = 5
x = 4
5 = 7(4) - 2
5 = 28 - 2
5 = 26
No
______________
y = 5

What is the greatest factor of 48x²and 32x³
Answer:
Step-by-step explanation:
Write the prime factors making up the two expressions
48x^2: 2 * 2 * 2 * 2 * 3 * x * x
32x^3: 2 * 2 * 2 * 2 * 2 * x * x * x
Underline what is common to both
The highest common factor is 2 * 2 * 2 * 2 * x * x
The highest common factor is 16x^2
This may look very simplistic, but try a question like this
5397691 and 3271021

11/6=n+7/9 what does n equal
Answer:
n = 19/18
Step-by-step explanation:
11/6 = n + 7/9
-n + 11/6 = 7/9
-n = 7/9 - 11/6
-n = -19/18
n = 19/18
Answer:
n = 19/18
Step-by-step explanation:
The equation 11/6=n+7/9 has fractions with two different denominators (6 and 9). The LCD is 18, which is the smallest number evenly divisible by 6 and 9. Thus, we can rewrite 11/6=n+7/9 as:
33/18 = (18/18)n + 14/18 (Now all three denominators are the same: 18)
Then 33 = 18n + 14, or
19 = 18n
Dividing both sides by 18, we get n = 19/18
Check: Is 11/6 = 19/18 + 7/9 true? YES

How is it 86 I neeeed Explainatiob pleaseeee!!!!!
Answer:
it is 86
Step-by-step explanation:
House 1 has 6 sticks. House 2 has 11, house 3 has 16, and the pattern goes on. Each following house uses 5 more sticks. At design 17, we can use this pattern to solve for it. We would do 5*17, remembering to add 1 as house 1 has its own additional stick. 5*17 + 1 = 86

Find angles A, B, C, D, & E.
Answer:
Step-by-step explanation:
B = 35 {Alternate interior angles}
C = 75 {Corresponding angles}
D + 75 = 180 {Linear pair}
D = 180 - 75
D = 105
A = C {Corresponding angles}
A = 75
E = A {Alternate interior angles}
E = 75
