Answer:
9 1/2
Step-by-step explanation:
The answer is B.
Slope is 3; point (2,7)
7=3(2)+B
7=6+B
1=B
M=3
y=3x+1 slope intercept form
3x -y = -1 standard form
Answer:
x=-1 and y=4
Step-by-step explanation:
y=-3x+1
2x+5y=18
Put x and y on the same side for 1st equation
3x+y=1
2x+5y=18
Multiply top by -5
-15x-5y=-5
2x+5y=18
Add both equations onto each other
-13x=13
x=-1
Plug x=1 into any equation used
2(-1)+5y=18
-2+5y=18
5y=20
y=4
Answer:
f(-5)= 28
Step-by-step explanation:
The function is:
f(x)= x^2-2x-7
To find the answer put the value of -5 for all x's.
f(x)= x^2-2x-7
f(-5)=(-5)^2 - 2(-5)-7
f(-5)=25+10-7
f(-5)=35-7
f(-5)= 28 ...
Answer:
excluded value is 1/2
Step-by-step explanation:
The excluded value is the value when the denominator is equal to zero
1 -2x =0
Subtract 1 from each side
-2x = -1
Divide by -2
-2x/-2 = -1/-2
x = 1/2
The excluded value is 1/2
