You’re given that m=7 (slope is 7), so setup the slope-intercept form with that info: y = 7x + b.
Now you need to find b. Plug in (3,11) for x and y, x=3 and y=11.
11 = 7*3 + b
Notice the only variable left is b, so you’ll find b this way.
11 = 21 + b and then subtract 21 from both sides:
11 - 21 = b
-10 = b
Plug that back into the equation and you have y = 7x -10
Answer:
Well t has to be zero, for r+t to equal r itself. so -s is equal to r, because it's r-0. Answer is C
Answer:
(3x-2)
Step-by-step explanation:
3x² + 4x - 4
look for two factors whose product is (3)(-4)=<em>-12</em> and sum is +4
The factors will be +6 and -2
substitute these factors inplace of 4x to get:
3x² - 2x + 6x - 4
then factorize:
x(3x-2)+2(3x-2)
finally we get factors: (3x-2)(x+2)
Step-by-step explanation:
F(x)=2x
but x= 4
F(x)= 2(4)
F(x)= 8
1/8 is same as 8
