Answer: y=8x
Step-by-step explanation:
Slope-intercept form is y=mx+b, where m is slope and b is y-intercept. To find slope, we take any two points and plug them into [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]. Let's use (1,8) and (2,16).
[tex]m=\frac{16-8}{2-1}=\frac{8}{1} =8[/tex]
Now, we know that m=8. Looking at the graph, we can see that the y-intercept is b=0 because the line passes through the y-axis at (0,0). To be sure, let's plug in a point into our equation to see if the y-intercept is correct.
y=8x+b [plug in (1,8)]
8=8(1)+b [multiply]
8=8+b [subtract both sides by 8]
b=0
Therefore, our equation is y=8x.

Answer:
Step-by-step explanation:
i.
(10y+x) - (10x+y) = 63 ---> This subtracts the original from the number with the reversed digits, and makes it equal to 63, so the number increases by 63
y - x = 7 ---> We have to prove this is true, so put it into the original equation
y = 7 + x ---> manipulate the above equation, and substitute it into the original equation
[10 (7 + x) + x] - [10x + (7 + x)] = 63
(70 + 11x) - (11x + 7) = 63
63 = 63 ---> Solve the equation, and because it comes out to be true, you proved that y - x = 7
ii. a.
(10x + y) + (10y + x) = 99 ---> The sum of the original and reversed numbers
x + y = 9
y = 9 - x ---> substitute this into the original equation
[10x + (9 - x)] + [10 (9 - x) + x] = 99
(9x + 9) + (90 - 9x) = 99
99 = 99

A bakery sells six cookies for every one cake. Yesterday the store
sold 154 cookies and cakes combined. How many cakes were sold?
Answer:
22 cakes were sold.
Step-by-step explanation:
In order to solve this, add the cookies and cakes together (6+1=7) to get 7. Next, divide the cookies and cakes sold combined and divide that by the 7. 154/7=22. You sold 22 cakes and 132 cookies.
To check this answer multiply 6*22=132. Then multiply 22*1=22.
And add; 132+22=154.

An ice cream truck driver used the equation Y=KX to show how much money he made selling 9 ice cream bars. He determined he'd make $24.93. How much did he make per bar sold?
Answer:
$2.77 per bar sold
Step-by-step explanation:
Hi there!
We're given that selling 9 ice cream bars could make the truck driver $24.93. To find how much he'd make per bar sold, divide $24.93 by 9 ice cream bars:
24.93 ÷ 9 = 2.77
Therefore, the truck driver would make $2.77 per bar sold.
We could also find this answer using the given equation, y=kx.
y=kx
Let y equal the earnings. Let x equal the number of ice cream bars sold. Let k equal how much the driver would make per bar sold.
24.93=k(9)
24.93=9k
x=2.77

Step-by-step explanation:
8x-27=6x+7
8x=6x+34
2x=34
x=17
8(17)-27= 109
Answer: 109
Step-by-step explanation:
i'm not entirely sure of this answer as its been a while since ive done problems like this, however, i think the steps to solve are setting (8x-27) equal to (6x+7). Once you do that, you can solve for x. Substitute x into angle DBC to find the answer.
What is this? I don’t know the answers plz help
Answer:
C
Step-by-step explanation:
Answer:
c.
Step-by-step explanation:
Starting with the multiplications, first the multiply matrix A by -4, so we multiply every value in the matrix by -4 and we get
16 16 -4
-4 -16 -28
-8 -12 -12
Then we do the next multiplication which is 8 by matrix B, so once again we multiply every value in the B matrix by 8
16 72 -72
64 64 -16
32 80 8
Now that we did both multiplications, just need to sum the results, so we sum each value of matrix A with the value on the matrix B that's on the same spot
16 + 16 16 + 72 -4 + (-72)
-4 + 64 -16 + 64 -28 + (-16)
-8 + 32 -12 + 80 -12 + 8
And the final result is
32 88 -76
60 48 -44
24 68 -4
So it's option c

what are factors of -12 that add up to -2
Answer:
Step-by-step explanation:
the only factors of -12 is: 12 and -1 or -12 and 1, 2 and -6 or -2 and 6, and finally 3 and -4 or -4 and 3. There is no even factor of 12 that adds to -2, unless you use decimals which even then I don’t think there is an awnser. So the awnser would be nonfactorable.

The value of x is 108.
What is HCF?The highest common factor is defined as the set of numbers with the highest common multiple. The highest positive integer with more than one factor in the set is HCF.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
We have been given that the HCF of 90 and x is 18.
And the LCM of 90 and x is 540.
We have to determine the value of x.
Since the product of two numbers equals the product of their HCF and LCM.
So 90 × x= HCF × LCM
Substitute the values of given data,
⇒ 90×x = 18×540
⇒ 90×x = 9720
⇒ x = 9720/90
⇒ x = 108
