Answer:
b = 2a + 3
Step-by-step explanation:
Here, we want to write an expression for b in terms of a
Mathematically, the formula for the slope of a line is
m = (y2-y1)/(x2-x1)
m is 2
(x1,y1) = (-1,1)
(x2,y2) = (a,b)
Substituting these values
2 = (b-1)/(a-(-1))
2 = b-1/a + 1
2(a + 1) = b-1
2a + 2 = b- 1
2a + 2 + 1 = b
b = 2a + 3

What are Factors of a Number?
Numbers that divide an original number evenly or precisely are known as its factors. A factor is a whole number that can divide a larger number in two equal parts. A factor is a number that divides another number, leaving no remainder
Given data ,
The number = 42
The number has both negative and positive factors
The factors of the number 42 are
The positive factors of 42 are 1 , 2 , 3 , 6 , 7 , 14 , 21 , 42
The negative factors of 42 are -1 , -2 , -3 , -4 , -6 , -7 , -14 , -21 , -42
Product of -14 and -3 = -14 x -3
= 42
Sum of -14 and -3 = ( -14 ) + ( -3 )
= -17
Hence , -14 and -3 are the two factors of 42 which has as a sum of -17

its a function or not fuction?
answer:
it's a function
step-by-step explanation:
according to g00gle- in mathematics, a function is a binary relation between two sets that associates to each element of the first set exactly one element of the second set. typical examples are functions from integers to integers, or from real numbers to real numbers.
but the simple definition is that a function is when the x value isn't being repeated. and since in your case it isn't, the table is a function
another way to solve-
for this, we will put the pairs into a graph then perform the line test-
as you can see each point has its own individual line, therefore, meaning it passed the vertical line test
good luck :)

Answer:
3054
Step-by-step explanation:
When you round to the nearest unit, in this case inch, you need to look at the tenths place.
5 or more raise the score
4 or less, let it rest.

Step one
given
A coat at a store is originally priced at $54.99
The store marks down the price down to $32.99
Required
the percent decrease
Step two:
the percent decrease= change in price/ old price*100

A label is placed around the juice box below, not including the bases. Determine the surface area of the label
Answer:
3 In²
Step-by-step explanation:
Talking about surface area, the total area of an object is taken into consideration.
NB: Kindly check the attached picture for the diagram of the 3D object.
In this question, the surface area has to be determined and we will have to take into consideration all the area of the 3D object given in the question.
Surface Area = 6 × k².
Surface area = 6 × ( 1.8 × 1.8) cm².
Surface Area = 19.44 cm².
The next thing to do here is to convert the cm² to in². Therefore, 19.44 cm² ------> x in².
19.44 × 0.155 in² = 3 in².
The circumference of each of the smaller circles is 12 mm. Find the area of the shaded region.
Answer:
11.45mm^2
Step-by-step explanation:
Given data
Circumference= 12mm
The expression for the circumference is
C= 2πr
12= 2*3.14*r
12= 6.28r
r= 12/6.28
r= 1.91mm
Hence the area of each small circle is
A= πr^2
A= 3.14*1.91^2
A= 3.14*3.6481
A=11.45mm^2

The grades for 200 students at a middle school are represented in the graph below how many more students earned Cs then Ds
Answer:
B. 60
Step-by-step explanation:
There are a total of 200 students here, and 45% got Cs, to find how many got Cs, multiply 200 by 45%, or 0.45: 200*0.45 = 90, 90 people got Cs.
15% got Ds, multiply 200 by 15%, or 0.15 to get 30, 30 got Ds
The amount who got Cs minus the amount who got Cs is 90 - 30 = 60, 60 more students got Cs than Ds
