Answer:
Now how did I get the translation rule (x + 1, y + 3). Well basically, I did this :-
-4 - (-5) = 1
12 - 9 = 3
Now let us plug it in the translation rule to see if I get (-4, 12).
(x + 1, y + 3)
(-5 + 1, 9 + 3)
(-4, 12)
I get the same answer given in the problem. Hope this helps, thank you !!

which graph shows a system of equations that can be entered into a graphing calculator to solve 16.9x-3.2x+18
Answer:
36.08
Step-by-step explanation:
This my answer thanks
The equation that can be entered into a graphing calculator to solve 16.9x–2.3=3.2x+18 are y = 16.9x - 2.3 and y = 3.2x + 18 respectively. Option B is correct.
What is the equation?The equation is the relationship between variables and represented as y = ax + b is an example of a polynomial equation.
The equation is
16.9x - 2.3 = 3.2x + 18
From options
y = 16.9x - 2.3 and y = 3.2x + 18
Hence, the equation that can be entered into a graphing calculator to solve 16.9x–2.3=3.2x+18 are y = 16.9x - 2.3 and y = 3.2x + 18 respectively.

look at the graph of a line and write its equation
Answer:
y=-2/3x-1
Step-by-step explanation:
You can fins the slope (or the m in y=mx+b) by counting how many units up/down and over it takes to get to another solid point and configuring it into a fraction rise/run. in this case you go down 2 units and over 3 units to get -2/3
to get the y-intercept (the b in y=mx+b) you look at where the lince intercepts the y-axis in this case it is at -1

For the expression 6 - y + 3, determine the coefficient for the variable
term.
-1
0
3
6
Answer:
Step-by-step explanation:
The coefficient of a variable is always the number before the variable, if there is no number before a variable the coefficient is always 1.
In this case, since the subtraction sign is before the variable, you will need to make the variable positive by making the coefficient of variable y, -1.
In short terms, your answer is -1. :)
How is 4.4^x the same as 4^x+1????
Answer:
Step-by-step explanation:
From laws of indices, we know that;
a^(x) × a^(y) = a^(x + y)
Similarly, in our question, 4 • 4^(x) implies that; 4¹ × 4^(x)
Since 4 can be also expressed as 4¹.
Thus,this equals; 4^(x + 1)
This expression is same as the other one given in the question as 4^(x + 1).
Thus, 4 • 4^(x) is the same as 4^(x + 1).

14. Write the equation in slope-intercept form that passes through the two points.
(1, 2) and (3,-8)
Answer: y=5x+7
Step-by-step explanation:
If you draw a graph or use a graphing calculator the points and then connect them you will see that the y-intercept is 7 and the slope is 5/1. Slope intercpt form is y=mx+b. So the equation is y=5x+7.
Answer:
let (x1,y1)=(1, 2)
and(x2,y2)=(3,-8)
Step-by-step explanation:
we have
y-y1=(y2-y1)(x-x1)/(x2-x1)
y-2=(-8-2)(x-1)/(3-1)
y-2=-10(x-1)/2
y-2=-5(x-1)
y-2=-5x--5
y+5x=5+2
5x+y=7 is the required equation.note :-×-=+
–19w + 11 = –17w − 19
w=
Please help, will mark brainliest to correct answer!
Answer:
w = 15
Step-by-step explanation:
We have an expression and are asked to solve for w.
-19w + 11 = -17w - 19
Subtract 11 from both sides :
-19w = -17w - 30
Add 17w to both sides :
-2w = -30
Divide -2 from both sides to isolate w :
w = 15
What is the unit rate of y = 6x?
The unit rate when y should be equivalent to 6x should be considered as the 1:6.
Calculation of the unit rate:Since the equation be y = 6x
So, it can be like
y = 1 :6
Hence, we can conclude that The unit rate when y should be equivalent to 6x should be considered as the 1:6.

Ann and bill shared £440 in the ratio 9:2 Ann gives bill some of her money Bill now has the same amount as ann
Answer:
Bill gave Ann £220
Step-by-step explanation:
plz mark brainliest :D
Ann shared £360 and Bill shared £80.
What is ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
Given:
Ann and bill shared £440
Ratio = 9:2
Total is = 9+ 2= 11
So, Anna shred
= 9/11 x 440
= 360
and Bill shred
= 2/11 x 440
= 80
