Its would be orange because only two people liked it out of all the kids asked.
Use the integer rule if the negative sign in bigger than the positive minus but the answers sign should be negative, if they switch sides it doesn’t matter you need to see what value it is and, if you want to minus with a negative you have to plus them and then add the negative sign, if you get something like this (-2- -10) you have to change it to (-2 + 10), it’s a math rule to negatives to gather represents addition.
Answer:
In technical terms, the slope of the line is the change in y over the change in x. But I just like to think of it as rise over run. To find the slope of the line, pick two points on the line
Answer:
2.5 hours is the time it will take.
Step-by-step explanation:
50t + 55t-30 = 235
105t = 265
T = 2.5 hours (rounded to one d.p)
Answer:
x = 4 or x = -13/4 = -4.33
Step-by-step explanation:
log (3x - 2) + log (x + 1) = 2 - log 2
Note 2 is also equals to log 100
log (3x - 2) + log (x + 1) = log 100 - log 2
log (3x - 2)(x + 1) = log (100/2)
log 3x² + 3x - 2x - 2 = log 50
log 3x² + x - 2 = log 50
3x² + x - 2 = 50
3x² + x - 2 - 50 = 0
3x² + x - 52 = 0
find the number to multiply that will give you -52 × 3 = -156 and add to give you 1. The numbers are -12 and 13.
3x² - 12x + 13x - 52 = 0
3x(x - 4) + 13( x - 4) = 0
(3x + 13)(x - 4) = 0
x = 4 or x = -13/4 = -4.33
If you insert 4 in the logarithm equation you will see that the left side is equal to the right
log (3x - 2) + log (x + 1) = log 100 - log 2
log 10 + log 5 = log 50
log 50 = log 50
