Answer:
y = 10
Step-by-step explanation:
If x = -2
10x + 4y = 20
10(-2) + 4y=20
-20+4y=20
4y= 20+20
4y=40
y=10
If x=2 and y=10
13x - 4y = -66
13(-2) - 4(10) =-66
-26 -(-40) = 66 so it all checks out!!

If John can paint half of a room in two-thirds of an hour, what part of the room can he paint in a full hour?
Answer:
0.75(3/4) part of the roomStep-by-step explanation:
Step one:
given data
we can express the given data mathematically as
John can paint 0.5room in 2/3 hours
let the part of the room he can paint in an hour be x
so
if he takes 2/3 hours to paint 0.5 room
then he will take 1 hour to paint x
cross multiply we have
x= 0.5/2/3
x=0.5*3/2
x= 1.5/2
x=0.75 part of the room
75/100= 15/20=3/4 part

The exponential function g, whose graph is given below, can be written as g(x)=a*b^x
Complete the equation for g(x)
PLEASE HELP!!!!
Answer:
g(x) = [tex]9(\frac{1}{3})^x[/tex]
Step-by-step explanation:
Exponential function 'g' that can be written as g(x) = a.bˣ
From the graph attached,
Graph of the function passes through two points (0, 9) and (1, 3)
g(0) = a.b⁰
9 = a
Similarly, g(1) = a.b¹
3 = a.b
3 = 9(b)
b = [tex]\frac{3}{9}=\frac{1}{3}[/tex]
Therefore function will be,
g(x) = [tex]9(\frac{1}{3})^x[/tex]

(3,-1) slope= 2 what is the equation?
Answer:
y = 2x - 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2, thus
y = 2x + c ← is the partial equation
To find c substitute (3, - 1) into the partial equation
- 1 = 6 + c ⇒ c = - 1 - 6 = - 7
y = 2x - 7 ← equation of line

Each morning, Stacey makes 20 cinnamon bagels for his customers at Barney's Bagels. Because of a recent increase in the popularity of cinnamon bagels, she has increased the number she bakes each morning by 80%. How many cinnamon bagels does Stacey now bake each day?
Answer: Stacey now bakes 36 cinnamon bagels.
Step-by-step explanation:
Given: Each morning, Stacey makes 20 cinnamon bagels.
She has increased the number she bakes each morning by 80%.
Number of cinnamon bagels Stacey bake = 20+80% of 20
= 20+ (0.80)x 20 [To remove % , divide number by 100, So 80%=0.08]
= 20+16 [(0.80)x 20=16 ]
= 36
Hence, Stacey now bakes 36 cinnamon bagels.

Alexandro received two quotes for new carpet for his home. The quote from Home Depot is $0.20 less per square foot than the quote from Lowe's. If Alexandro plans to buy 1,300 square feet of carpet, how do his total costs from the two companies compare? *
Answer:
Total cost as per Lowe's is $260 more than that of Home Depot.
Step-by-step explanation:
Given that:
Alexandro received two quotes for new carpet.
One from Home Depot and other from Lowe's.
Let quote from Home Depot = [tex]\$x[/tex] per sq foot
As per question statement,
The quote from Lowe's = [tex]\$x[/tex]+0.20 per sq foot
Alexandro plans to buy 1,300 square feet of carpet.
Total Cost as per Home Depot's quote = [tex]\$1300x[/tex]
Total Cost as per Lowe's = [tex]\$(x+0.20)\times 1300 = \$1300x + \$260[/tex]
Now taking the difference of the total cost:
Lowe's total cost - Total cost as per Home Depot.
[tex]\$1300x+\$260 - \$1300x \\\Rightarrow \$260[/tex]
So, the answer is:
Total cost as per Lowe's is $260 more than that of Home Depot.
Examine the following table of points, which are all on a certain line.
x y
−2 4
0 2
1 1
3 −1
What is the slope of this line?
Enter your answer as a number, like this: 42
Or, if the slope is undefined, enter a lowercase letter "u," like this: u
9514 1404 393
Answer:
-1
Step-by-step explanation:
The slope formula is useful:
m = (y2 -y1)/(x2 -x1)
m = (2 -4)/(0 -(-2)) = -2/2 = -1
The slope of this line is -1.
_____
The points on the line drop 1 unit for each 1 unit to the right.
m = rise/run = -1/1 = -1
