Graph the line with slope -1 passing through the point (2,-4)
Answer:
put a dot on point (2,-4) then go one to the right and one down hope this helps
Step-by-step explanation:
The equation of the line having a slope of -1, and passing through the point (2, -4) is x + y = - 2.
What is the equation of a line?
The equation of a line is the relation between the x-coordinates and y-coordinates of the points on the line, such that all (x, y) points, satisfies this equation.
The slope-intercept form of a line is y = mx + b, where m is the slope and b is the y-intercept of the line.
How to solve the question?In the question, we are asked to graph the line with slope -1, and passing through the point (2, -4).
We know that, the slope-intercept form of a line is y = mx + b, where m is the slope and b is the y-intercept of the line.
Substituting m = -1, x = 2, and y = -4, in the equation, we get:
-4 = -1(2) + b,
or, b = -4 + 2 = -2.
Thus, the equation of the line is: y = -1(x) - 2,
or, x + y = -2.
Thus, the equation of the line having a slope of -1, and passing through the point (2, -4) is x + y = - 2.
The graph for the equation is attached.

If 6×2 + 6y2 = 13xy, what is the ratio of x to y?
Answer:
Since 6X2 + 6Y2 = 13 xy
-- 6X2 / XY + 6Y2/XY =13
---> 6 X/Y + 6 Y/X =13
6a + 6/a =13
---> 6a2 + 6 =13a
---> 6a2 -13a +6 =0
---> 6a2 -9a - 4a +6 =0
---> (2a-3) (3a-2) =0
2a-3 = 0
a= 3/2
So the Ratio will be = 3:2

Explain how an enlargement of reduction in the dimensions of a building would cause a change in the scale factor.
Answer:
The scale factor represents a proportional relationship between the scale drawing and the building’s dimensions. If the dimensions change, then the scale factor must also change to preserve the relationship.
Step-by-step explanation:
Answer:
The scale factor is a proportional relationship. The scale factor represents a proportional relationship between the scale drawing and the building’s dimensions. If the dimensions change, then the scale factor must also change to preserve the relationship. Enlargements have a scale factor greater than 1. Reductions have a scale factor between 0 and 1. The proportion should be preserved.

What does x equal in this equation x= .49x^2
Answer:
x=0, 2.04 (2dp)
Step-by-step explanation:
Assuming is it 0.49, our equation currently looks like this:
x = 0.49x^2
The first step is to move all x terms to one side which we can se by subtracting an x from both sides.
x - x=0.49x^2 - x
0 = 0.49x^2 - x
Now we can factorize by pulling out the x, which is a common factor:
0=x(0.49x-1)
We can now see that one of the solutions is x = 0, because anything in the brackets multiplied by 0 is 0.
To find the other solution we can divide both sides by x and solve:
0/x=x(0.49x - 1)/x
0=0.49x-1
1=0.49x
Now we just divide both sides by 0.49 to get our second answer!
1/0.49=0.49x/0.49
2.04=x
x = 0, 2.04 (2dp)

What is a double-number line?In a double number line diagram, equivalent ratios are represented by two parallel number lines.
Given that, the hen takes 25 hours to produce 1 egg.
1 egg = 25 hours
3 eggs = 25 × 3 hours
3 eggs = 75 hours
Similarly,
100 eggs = 2500 hours
and,
12 eggs = 300 hours
Hence, the completed table is:

3 medium cars to 1 small car
18 medium cars to 6 small cars
Answer:
Yes
Step-by-step explanation:
3 medium cars to 1 small car can be made into a fraction like this: [tex]\frac{3}{1}[/tex] or [tex]\frac{1}{3}[/tex]. But you must be consistent if the denominator represents medium cars or small cars.
For this, I'm just going to make medium cars the numerator.
18 medium cars to 6 cars can be made into a fraction like this : [tex]\frac{18}{6}[/tex].
When you divide both fractions in a calculator (or in your head), you will realize that they both are the same value (equivalent).
[tex]\frac{3}{1}=\frac{18}{6} = 3[/tex]
[tex]\frac{1}{3} = \frac{6}{18} = .3333333[/tex]
These ratios are equivalent.

Answer:
The function values of [tex]{q(2)}[/tex] is [tex]\bold{\dfrac{11}{4}}[/tex], [tex]q(0)[/tex] is UNDEFINED and [tex]q(-x)[/tex] is [tex]\bold{2+\dfrac{3}{x^2}}[/tex]

[tex]q(t)=\dfrac{2t^2+3}{t^2}[/tex]
Part (a)
Find [tex]q(2)[/tex]
Put [tex]2[/tex] for [tex]t[/tex] for finding the value of the function [tex]q(2)[/tex].

Lillian earned $397.50 at her job when she worked for 25 hours. What was her hourly wage, in dollars per hour? On the double number line below, fill in the given values, then use multiplication or division to find the missing value.
Answer:
$15.9
Step-by-step explanation:
$397.5 = 25 hour
=> x dollars = 1 hour
=> 397.5 * 1 = 25 * x
=> 397.5 = 25x
=> 397.5/25 = 25x/25
=> 15.9 = x
So, for 1 hour he earns $15.9
