answer is D
graduent should be m¹×m²=-1
and should be the inverse of the other
Answer:

Step-by-step explanation:
We want to find the equation in point-slope form of the line that passes through the point
and has slope
.
The point-slope form is given by the formula;

where
is the slope and
is a point on the line,
We substitute the values into the formula to obtain;
The required equation is 
The answer is: [D]: " 157" .

g(x) = 8x² + 9x − 7 ;
g(4) = 8(4²) + 9(4) <span>− 7 ;
</span>
= 8(4*4) + 36 <span>− 7 ;
</span>
= 8(16) + 36 <span>− 7 ;
</span>
= 128 + 36 <span>− 7 ;
</span>
= 164 − 7 ;
= <span>157 .</span>

Answer:
Total tickets = 70
Total cost = $550
Adult's ticket = $9
Child's ticket = $5
Difference = 9 - 5 = $4
Assume all 70 are child's tickets
5 x 70 = 350
But the total cost was 550
550 - 350 = $200
The $200 must have come from Adult's tickets, which has a difference of $4.
200 ÷ 4 = 50
So there are 50 adult's tickets.
70 - 50 = 20
And there are 20 child's tickets.
