Which of these describes the equation –18x + 9y = –416?
A
The equation is not linear because it has 2 variables, not 1.
B
The equation is not linear because it is not in the form y = mx + b.
С
The equation is linear because it has variables with exponents of 0.
D
The equation is linear because it can be rewritten in the form y = mx + b.
Answers
Answer:
We conclude the equation is linear because it can be rewritten in the form [tex]y = mx + b[/tex].
Hence, option D is correct.
Step-by-step explanation:
The slope-intercept form of the line or linear equation
[tex]y = mx+b[/tex]
where
[tex]m[/tex] is the slope[tex]b[/tex] is the y-intercept
Important Tip:
The graph of a linear equation is always a straight line.
Convert the given equation in the slope-intercept form
[tex]18x + 9y = -416[/tex]
subtract 18x from both sides
[tex]18x+9y-18x = - 18x-416[/tex]
simplify
[tex]9y = -18x - 416[/tex]
divide both sides by 9
[tex]y=-2x-\frac{416}{9}[/tex]
Now, comparing the equation [tex]y=-2x-\frac{416}{9}[/tex] with a slop-intercept form of linear equation
The slope m = -2The y-intercept b = -416/9Therefore, we conclude the equation is linear because it can be rewritten in the form [tex]y = mx + b[/tex].
From the attached graph, is also clear that the graph of the equation [tex]y=-2x-\frac{416}{9}[/tex] is a straight line.
Hence, option D is correct.

Jamie drank 4 times as much juice as Brodie. Jamie drank 280 milliliters of juice.How much did Brodie drink ?
Answers
Answer:
Brodie drank 70 milliliters
Step-by-step explanation:
280 divided by 4 equals 70
To check: 70 x 4 = 280
Hence, the Brodie drink [tex]280[/tex] milliliters.
What is the simplification?
Simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.
Here given that,
Jamie drank four times as much juice as Brodie. Jamie drank [tex]280[/tex]milliliters of juice.
So,
[tex]\frac{280}{4}=70[/tex] millilitres
And, Jamie drank four times as much juice as Brodie

what is 512.3 divided by 10
Answers
Answer:
51.23
Step-by-step explanation:
Hi !
So basically all you need to do with an equation like this move the decimal.
And the direction you move it depends on the value of the largest digit as well as if it is larger or smaller than 0.
So lets look at 10 and make it 10.0 so its a decimal and make things a bit easier.
So 10.0 is just one digit moved in the decimal world. (100.0 would be 2, 1000.0 would be 3, and so on.)
And 10.0 is greater than 0.
Greater than 0 = Move decimal left
Less than 0 = Move decimal right
So now we know to move one space to the left.
512.3
>
One to the left
>
51.23
And its that easy, that is your answer.
I hope this helps!

F(x)=bx^2+32 For the function f defined above, b is a constant and f(2)=40. What is the value of f(-2)?
Answers
Answer:
f(-2) = 0
Step-by-step explanation:
Given that:
f(x) = bx^2 + 32
f(2) = b(2)^2 + 32
f(2) = 4b + 32
f(2) = 4b = -32
f(2) = b = -32/4
f(2) = b = -8
Thus;
f(-2) = -8(-2)^2 + 32
f(-2) = -8(4) + 32
f(-2) = -32 + 32
f(-2) = 0

Ms.Lee bought some Reese and a bag of chips. They cost $4.36 altogether. The chips cost $1.60 more than the Reese. How much did the Reese cost?
Answers
Answer: $1.38
Step-by-step explanation:
Let the value of the Reese be represented by x
Since the chip cost $1.60 more than the Reese, then the chip will be:
= x + 1.60
Since they cost $4.36 altogether, the value of the Reese will be:
x + (x + 1.60) = 4.36
2x + 1.60 = 4.36
2x = 4.36 - 1.60
2x = 2.76
x = 2.76/2
x = 1.38
The Reese cost $1.38

1.36
