Answer:
it is negative
Step-by-step explanation:
a negative plus a negative make a more negative number
Answer:
Y= 5/3x + -9
Step-by-step explanation:
Well its
y=mx+b
m is slope
B is y intercept
To fidn y intercept, just make sure the X value of any coordiante given is 0 and the y value is not 0. So basically anything with (0, y), thats your y intercept.
Slope Is just
(y2-y1) / (x2-x1)
You didn’t attach the line plot but I’ll do my best.
1 pound = 16 ounces
It says of a pound dog toys, meaning that we will have to do multiplication:
1/2 * 1 pound
= 1/2 * 16 ounces
= 8 ounces
5/8 * 16 ounces
= 10
Next, find the difference:
10 - 8 = 2
The total weight of 5/8 of a pound of dog toys is 2 ounces greater than 1/2 of a pound of dog toys.
Also, the last bit of the question is worded incorrectly. 5/8 > 1/2 right off the bat. I’m not sure who designed the question but I think you should let them know since it would likely confuse individuals who encounter this question. Hope this helps!
Follow the steps for 8
(1) 8 * 2 = 16
(2) 16 * 5 = 80
Note: you could just combine the first 2 steps and multiply by 10 to start with. Much easier: just add a 0 onto 8.
(3a) 12 * 8 = 96
(3b) 96 - 24 = 72
(3c) So you want to take 1/2 72 which is 36
(4) 36 + 80 = 116
Let's try this with x.
(2) x * 10 = 10x
(3) 1/2 (12*x - 24)
(3) 10x + 1/2 (12x - 24)
(3) 10x + 6x - 12
(4) 16x - 12
Problem B
Math wiz would add 12 to the number given to her and then divide by 16. That's pretty complicated to do quickly.
For example Let the original number be 1221
(2) Multiply by 10 12210
(3) Take 1/2 the difference between 12 times 1221 and 24 which is 1/2(14652 - 24) = 7314
And add this result to 12210
7314 + 12210 = 19524
Tell her the number. She has to add 12
19524 + 12 = 19536 And divide by 16
to get 1221.
Pretty complex even for a wizard.
