Answer:
-7
Step-by-step explanation:
y-3=-2(x+5)
So we need to put this in slope-intercept form...
y - 3 = -2x -10 (You use the distributive property)
Then shift the -3 over to meet the other constant -10 by addition.
y - 3 = -2x -10
+3 + 3
y = -2x -7 since y = mx + b is in slope intercept form m = slope and b = y intercept, therefore the y intercept is -7

Answer is YES
Because
2 ones = 2 x 1 = 2 and 20 tenths = 20 x 0.1 = 2
Answer:
-15/6
Step-by-step explanation:
If you look at the first number in each point, the x coordinate, you see the 2nd point is 6 forward from the 1st point. Now the 2nd number is the y coordinate, and you can see it goes down 15 from the 1st coordinate. So y/x is the slope.
Answer:
George has 64 nickel and 32 dimes.
Step-by-step explanation:
Normally, we have:
One nickel = 5 cents
One dime = 10 cents
One dollar = 100 cents
Therefore, total number of cents that George has can be calculated as follows:
Total number of cents = $6.40 * 100 = 640 cents
Based on the above, we have:
640 cents = 640 / 5 = 128 nickel
640 cents = 640 / 10 = 64 dimes
Therefore, we have:
128 nickel = 64 dimes
Divide through by 2 in order to share 640 cents equally, we have:
128 nickel / 2 = 64 dimes / 2 => 64 nickel = 32 dimes
Since 64 minus 32 is equal to 32, it therefore implies that George has 64 nickel and 32 dimes.
