look at the pic attached:
Which shows the equation below written in the form ax2 + bx + c = 0? 2x2 - 3 = -6x - 2
A. 2x2 + 6x - 5 = 0
B. 2x2 - 6x - 1 = 0
C. 2x2 + 6x - 1 = 0
D. 2x2 - 6x - 5 = 0
Answer:
C. 2x² + 6x - 1 = 0
Step-by-step explanation:
2x² - 3 = -6x - 2
2x² - 3 + 6x = -6x + 6x - 2
2x² - 3 + 6x = -2
2x² - 3 + 6x + 2 = -2 + 2
2x² + 6x - 1 = 0
Hope that helps.

A bike rental company charges a rental fee plus $8 per hour. If 6 hours costs $73, how much is the rental fee? Solve using an ALGEBRAIC EQUATION
Answer:
The rental fee is 25
Step-by-step explanation:
Total cost = rental fee plus cost per hours * number hours
t = f + 8*h where t = total cost, f = rental fee, h = hours
73 = f + 8*6
73 = f+ 48
Subtract 48 from each side
73 - 48 = f+48-48
25 = f
The rental fee is 25
What is the equation of the line that passes through the point (−6,3) and has a slope of -2/3?
Answer:
It's probably;
[tex] y = \frac{ - 2x + 21 }{3} [/tex]
Step-by-step explanation:
The Formular for equation on the line is given as m=y-y1/x-x1Where m = -2/3 , y1=3 and x1 = -6Then you substitute and solveII. Mr. Roy sold a cupboard to Mohan for RO 60 and earned a profit of RO 10. Mohan spent RO 27 to polish and repair the cupboard. He then sold it to Gopi at a profit of RO 8. After using the cupboard for a year , Gopi sold it to a furniture dealer for RO 90. Did Gopi make a profit or a loss in the deal? *
Answer:
Gopi made a loss in the deal
Step-by-step explanation:
To solve this question, we'll analyse each statement in the question one after the other.
From Roy to Mohan,
[tex]Selling\ Price = Ro.\ 60[/tex]
The profit of [tex]Ro.\ 10[/tex] goes to Roy
Mohan spent [tex]Ro. 27[/tex] on polish and repairs.
So, the cost price of the cupboard becomes
[tex]Cost\ Price = Ro.60 + Ro.27[/tex]
[tex]Cost\ Price = Ro.87[/tex]
He sells at a profit of [tex]Ro.8[/tex]. to Gopi
So, the selling price is:
[tex]Selling\ Price = Ro.8 + Ro.87[/tex]
[tex]Selling\ Price = Ro.95[/tex]
At this stage, the cost price of the cupboard to Gopi is:
[tex]Cost\ Price = Ro.95[/tex]
and
[tex]Selling\ Price = Ro.90[/tex]
Profit is calculated as:
[tex]Profit = Selling\ Price - Cost\ Price[/tex]
[tex]Profit = Ro.90 - Ro.95[/tex]
[tex]Profit =- Ro.5[/tex]
Because; the profit is negative, then it is a loss.
[tex]Loss = Ro.5[/tex]
Gopi made a loss in the deal

Answer:
Since dilation is not mentioned in the answer options, thus, the correct option is 'None of the above'.
Step-by-step explanation:
We know that when an object is dilated by a scale factor, it gets reduced, stretched, or remains the same, depending upon the value of the scale factor.
If the scale factor > 1, the image is enlarged If the scale factor is between 0 and 1, it gets shrunk If the scale factor = 1, the object and the image are congruentThe figure seems to have enlarged by a certain scale factor. Thus, the figure b is a result of dilation of the original figure by a certain scale factor.
Rotation, Reflection, and translation do not affect the size of the original figure.
Since dilation is not mentioned in the answer options, thus, the correct option is 'None of the above'.

Answer:
16.8
Step-by-step explanation:
you get this by taking the ratio of 12:30 and applying it to 42
you get 30 by taking the total of 12 + 18
you then divide 12 / 30 which equals 0.4
you then multiply 0.4 * 42 which gives you 16.8
if you were to solve for the other ratio you would divide 18 / 30
and then take the answer of that, 0.6 and multiply it by 0.6 * 42
then you have the other part of the ratio.

Graph the line that passes through the points (3,-4) and (3,-1) and determine
the equation of the line.
Answer:
The equation of a line:
x = 3The graph of the line is attached below.
Step-by-step explanation:
Given the points
(3, -4)(3, -1)Finding the slope between (3,-4) and (3,-1)
(x₁, y₁) = (3,-4)
(x₂, y₂) = (3, -1)
Using the slope formula
m = y₂-y₁ / x₂-x₁
= -1-(-4)) / 3 - 3
= -1 + 4 / 0
m = ∞
The slope of the line is undefined, then, by definition, the line would be a vertical line.
As the line that passes through the points (3,-4) and (3,-1)
For a vertical line, the value of x is the same for each and every value of y.Thus, the equation of a line:
x = 3The graph of the line is attached below.

PLEASE ANSWER FAST:
Zoey and her children went into a grocery store where they sell apples for $2 each and bananas for $0.50 each. Zoey has $8 to spend and must buy a minimum of 7 apples and bananas altogether. If x represents the number of apples purchased and y represents the number of bananas purchased, write and solve a system of inequalities graphically and determine one possible solution.
Answer:
(2,7)
Step-by-step explanation:
Variable Definitions:
x=
x=
\,\,\text{the number of apples}
the number of apples
y=
y=
\,\,\text{the number of bananas}
the number of bananas
\text{\textquotedblleft a minimum of 7 items"}\rightarrow \text{7 or more items}
“a minimum of 7 items"→7 or more items
Use a \ge≥ symbol
Therefore the total number of apples and bananas, x+yx+y, must be greater than or equal to 7:7:
x+y\ge 7
x+y≥7
\text{\textquotedblleft \$8 to spend"}\rightarrow \text{can spend \$8 or less}
“$8 to spend"→can spend $8 or less
Use a \le≤ symbol
One apple costs $2, so xx apples cost 2x.2x. One banana costs $0.50, so yy bananas cost 0.50y.0.50y. The total 2x+0.50y2x+0.50y must be less than or equal to \$8:$8:
2x+0.50y\le 8
2x+0.50y≤8
\text{Solve each inequality for }y\text{:}
Solve each inequality for y:
\begin{aligned}x+y\ge 7\hspace{30px}& 2x+0.50y\le 8 \\[0.8em] y\ge 7-x \hspace{30px}& 0.50y\le 8-2x \\[0.8em] \hspace{30px}& y\le \frac{8-2x}{0.50} \\[0.8em] & y\le 16-4x\end{aligned}
x+y≥7
y≥7−x
2x+0.50y≤8
0.50y≤8−2x
y≤
0.50
8−2x
y≤16−4x
Graph y\ge 7-xy≥7−x by shading up and graph y\le 16-4xy≤16−4x by shading down:
0
the number of apples
the number of bananas
x
y
0
the number of apples
the number of bananas
(2, 7)
Since the point (2, 7(2,7) is inside the double shaded region, one possible solution to the system of inequalities would be:
Zoey could buy 2 apples and 7 bananas.
Suppose the linear regression line y = 2.1x + 130 predicts sales based on the
money spent on advertising. If x represents the dollars spent in advertising,
and y represents the company sales in dollars, about how much can the
company expect in sales if it spends $150 in advertising?
Answer:
$445
Step-by-step explanation:
Linear regression line y=2.1x+130 predicts sales based on the money spent on advertising.
Linear regression represents the relationship between two variables. the value of y depends on the value of x.
x represents the dollars spent in advertising and y represents the company sales in dollars.
We need to find out sales y when $150 spends on advertising.
Plug in 150 for x and find out y
y = 2.1 x + 130
y = 2.1 (150) + 130
y= 445
The company expects $445 in sales
The company expects $445 in sales.
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
Linear regression line y = 2.1x + 130 predicts sales based on the money spent on advertising.
Now, Linear regression represents the relationship between two variables. the value of y depends on the value of x.
Here, x represents the dollars spent in advertising and y represents the company sales in dollars.
We need to find out sales y when $150 spends on advertising.
Plug in 150 for x and find out y as;
y = 2.1 x + 130
y = 2.1 (150) + 130
y = 445
Thus, The company expects $445 in sales.
