which is an equation of the line
a. y = x - 1
b. y= x + 1
c. y= -x -1
d. y= -x + 1
Answer:
the form is y = mx + b an db is the y intercept. the y intercept is 1 so it is not a or c. The slope is positive, so it is b!!!

Lin's family has completed 80% of a trip. They have traveled 32 miles. How long is the whole trip?
Answer: 50 miles
Find t:
0.70t = 35. Dividing both sides by 0.70, we get:
35
t = ----------- = 50
0.70
The total trip length is 50 miles.

which value for d makes the expressions 3d-4 and 12d÷6 is equivalent
a. 2
b.3
c.4
d.4
Answer:
"Evaluation" mostly means "simplifying an expression down to a single numerical value". Sometimes you will be given a numerical expression, wher all you have to do is simplify; that is more of an order-of-operations kind of question. In this lesson, I'll concentrate on the "plug and chug" aspect of evaluation: plugging in values for variables, and "chugging" my way to the simplified answer.

Find the distance between the points (-4.4, 9.9) and (-4.4, -5.6).
Answer:
14.3 and -1.2
Step-by-step explanation:
To find the distance between both points subtract the larger point from the smallest and that should give you the answer.
Select the solution(s) to the following equation: (3x−2)(x+5)=0 SELECT ALL THAT APPLY
x=3/2
x=5
x=-5
x=2/3
x=-2/3
x=-3/2
Answer:
Step-by-step explanation:
Check by direct substitution. If we begin by checking x = 3/2, we substitute 3/2 for x in (3x - 2)(x + 5), obtaining (9/2 - 2)(3/2 + 5), which is NOT zero. Therefore x = 3/2 is not a solution.
(3*5−2)(5+5)=0 False. x = 5 is not a solution.
(3*[-5]−2)([-5+5)=0 True. x = -5 is a solution
x = 2/3: (3*2/3 - 2)( ) = 0. True x = 2/3 is a solution
x = -2/3: ( )( ) = -17 1/3; so x = -2/3 is not a solution
x = -3/2: ( ) ( ) = -22 3/4; so x = -3/2 is not a soution

complete the statement of each of these rules:
a (+)×(?)=(+)
b (-)×(+)=?
c (?)×(-)=?
Answer:
a) (+) × (?) = (+)
(?) = (+)
b) (-) × (+) = ?
? = (-)
c) (?) × (-) = ?
? is undefined
Step-by-step explanation:
a) (+) × (?) = (+)
From the given equation in the question, by dividing both side of the equation by (+), we have;
((+) × (?))/(+) = (+)/(+)
(?) = (+)/(+) = (+)
Therefore, we have;
(+) × (+) = (+)
(?) = (+)
b) (-) × (+) = ?
From the given equation in the question we apply the operation rules as follows;
(-) × (-) = (+)
(-) × (+) = (-)
Therefore;
(-) × (+) = ? = (-)
? = (-)
c) (?) × (-) = ?
From the rules of multiplication, we have;
(-) × (-) = (+)
(+) × (-) = (-)
Therefore, when (?) = (-), ? = +, from which we have;
(?) ≠ ?, which is an error
Similarly, when (?) = (+), ? = -, therefore, (?) and ?, always changes sign
Therefore, the equation, (?) × (-) = ?, is undefined.

Find the slope of the points given, and show work
(2,4) and (-3,3)
Answer: 1/5
Step-by-step explanation:
Let's find the slope between your two points.
(2,4);(−3,3)
(x1,y1)=(2,4)
(x2,y2)=(−3,3)
Use the slope formula:
m=y2−y1/x2−x1
=3−4/−3−2
=−1/−5
=1/5

The perimeter of a rectangular area is 16ft.
Write an expression for the sum of the length and width.
Answer:
Length + Width = 8 ft
Step-by-step explanation:
"The perimeter of a rectangle is 16 ft."
A perimeter is the sum of four sides of a rectangle.
OR...
Perimeter = Side 1 + Side 2 + Side 3 + Side 4
A rectangle has "matching sides", so...
Length: Side 1 = Side 3
Width: Side 2 = Side 4
Therefore we can just say that:
Perimeter = (Length * 2) + (Width * 2)
We can pull the 2 out:
Perimeter = 2 * (Length + Width)
Since Perimeter = 18
16 = 2 * (Length + Width)
Divide both sides by 2
8 = Length + Width
Length + Width = 8 ft

You roll a number cube. Determine the theoretical probability of rolling a 4 or a 6.
Answer:
Both of them would have a 1/6 chance of being chosen
Step-by-step explanation:
Sorry I don't know if this is the answer you are looking for :(
Answer:
2/6 is read as "2 out of 6" or "2 in 6"
Step-by-step explanation:
Since there are 6 sides on a dice you have a 2 in 6 chance of rolling either a 4 or a 6. The probability of rolling one over the other would be 1/6
Hope this helps!

Answer:
A=35, B=55, and C=25
Step-by-step explanation:
Angle A and the angle next to it are linear pairs, so you can subtract 145 from 180.
if you already know Angle A, and that the other angle is 90 degress, you can add 90+35 and subtract it from 180 to get Angle B
Angle C is paired with the angle across from it (I forgot what the term is called) so it is 25 degrees.
