What is the equation of the line that passes through the point (6, 8) and has a slope 1/2
Korvikt [17]

Answer:

y=1/2x+5

Step-by-step explanation:

Plug it into the formula for a point and a slope.

(y-(y(subscript 1)))=(m)(x-(x(subscript 1)))

Y-8=1/2(x-6)

Then multiply the 1/2 to the x and -6. After you do that, move everything so that it has y by itself on the left. Your ending should be y=1/2x+5.

Two dice are rolled. Define the events as follows: A : sum of 7, B : doubles, C : sum of 8
love history [14]

Answer: for a sum of 7 would either be 6 and 1, 5 and 2 or 4 and 3. you can roll a double 1,2,3,4,5,6. the sum of 8 would be 2 and 6, 3 and 5 and a double 4,

Step-by-step explanation:

well the there are six sides on a die so 6 x 2 is 12 so the max sum you can get is 12. So you take 7 and you start adding up to 7, same thing for sum of 8. since there is 6 sides and a pair of dices you will roll six doubles

3. Find the difference between the two expressions.<br> (3/5x - 5y) - (4/5x + 2y
andriy [413]

Answer:

^{-1}/_{5}x-7y

Step-by-step explanation:

Our equation is

(^{3}/_{5}-5y)-(^{4}/_{5}+2y)

now we distribute the - and we get

^{3}/_{5}-5y-^{4}/_{5}-2y

Combine like terms

and now we have ^{-1}/_{5}x-7y
