m= y2 -y1 over
x2- x1
b = any y point you choose
[tex] - 6 - 3 = - 9[/tex]
[tex]3 - 0 = 3[/tex]

Answer:
5025.41
Step-by-step explanation:
$50.50 and 16 cents - $40.50 and 9 cents = $40.00 and 10 cents per mile. For x miles, we multiply $40.00 and 10 cents by x miles.
Also, we could convert dollars to cents by multiply it by 100 Since $1 =100 cents.
5066 - 40.59 cents = 5025.41 cents. For x miles, 5025.41 cents.
Write the equation of a line that is perpendicular to y = 1/2x - 7 with a y-intercept of 15.
What is the perpendicular slope?
What is the new equation?
Answer:
m = -2
y = -2x + 15
Step-by-step explanation:
so it's asking for the perpendicular slope so perpendicular means negative reciprocal so the negative reciprocal of 1/2 is -2
and since the question has already provided the y intercept, just write out the new equation in slope intercept form so y = -2x + 15. hope this helps

Nats sister has 5/6 as many songs on her mp player as he has on his mp player. His sister has 35 songs. How many songs does Nat have?
Answer:
29 songs
Step-by-step explanation:
Multiply 35 by 5/6 to get the number of songs Nat's sister has.
35*5/6=175/6
Or 29 1/3
But you can't have 1/3 of a song so...
29 songs

Then what is ∠ACB
degrees.
Answer:
67 degrees
Step-by-step explanation:
1. The exterior angle theorem states that the measure of an exterior angle of a triangle is equal to the sum of the two remote angles.
2. Given the information above, we can say that x + 60 = 127.
[tex]x + 60 = 127[/tex] [tex]x + 60 - 60 = 127 - 60[/tex] (Subtract 60 from both sides)[tex]x = 67[/tex]Therefore, m∠ACB is 67 degrees.

which binary value is equal to the decimal number 210?
Answer is 11010010.
What are the Rules to Convert Decimal to Binary?
Write down the number.
Divide it by 2 and note the remainder.
Divide the quotient obtained by 2 and note the remainder.
Repeat the same process till we get 0 as the quotient.
Write the values of all the remainders starting from the bottom to the top.
Step by step solution:
Step 1: Divide (210) successively by 2 until the quotient is 0:
210/2 = 105, remainder is 0
105/2 = 52, remainder is 1
52/2 = 26, remainder is 0
26/2 = 13, remainder is 0
13/2 = 6, remainder is 1
6/2 = 3, remainder is 0
3/2 = 1, remainder is 1
1/2 = 0, remainder is 1
Step 2: Read from the bottom (MSB) to top (LSB) as 11010010.
So, 11010010 is the binary equivalent of decimal number 210 (Answer).

Given that x = 2.2 correct to 1 decimal place, find the interval that
contains the value of 4x + 3. Give your answer as an inequality.
Answer:
11.8
Step-by-step explanation:
The solution is 11.0 < 4x + 3 < 12.0
The inequality equation is 11.0 < 4x + 3 < 12.0 , where the value of the equation 4x + 3 = 11.8 , when x = 2.2
What is an Inequality Equation?
Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the equation is P = 4x + 3
The value of x = 2.2
Correcting the value of x to one decimal place , we get x = 2.2
Substitute the value of x in the equation , we get
P = 4x + 3
when x = 2.2
P = 4 ( 2.2 ) + 3
P = 8.8 + 3
P = 11.8
Now , the inequality equation is 11.0 < 11.8 < 12.0
Hence , the inequality equation is 11.0 < 4x + 3 < 12.0 , where 4x + 3 = 11.8

The sum of two consecutive integers is -351. Find the larger integer.
Answer:
answer is -175
step to step explanation:
let's say that first integer is x and second is x+1
(x+1) + x = -351
2x +1 = -351
2x = -351 -1
2x = -352
x = -176
small integer is -176 and the largest integer will be -176+1 = -175
Square will be centered at the origin on the coordinate plane. A rigid transformation of preimage is performed to image ′′′′. Determine which of the following characteristics or corresponding parts will not remain the same.
A. The measure of ∠′ after a reflection across the line y = x
B. The coordinates of A' after rotations of 360°
C. The coordinates of B' after a translation of 3 units left and 2 units up
D. The perimeter of square A'B'C'D'
Answer:c
Step-by-step explanation:
Transformation involves changing the position of a shape in a coordinate plane.
The corresponding parts that will not remain the same is (c) the coordinates of B' after a translation of 3 units left and 2 units up
Reflection is a rigid transformation;
This means that, options (a) and (d) will remain unchanged for the image and the pre-image of square ABCD
Rotating a shape 360 degrees will return the shape to its original position.
This means that: (b) will remain unchanged
The coordinates of B' after translation will not remain the same, because the points will move to (x + 3, y + 2).
Hence, option (c) is true
