f(x) = 4x - 18
f(-3) - <em>put x = -3 to the equation of the function</em>
f(-3) = 4(-3) - 18 = -12 - 18 = -30
<h3>Answer: (-3, -30).</h3>
f(x) = -46
We have the equation:
4x - 18 = -46 <em>add 18 to both sides</em>
4x = -28 <em>divide both sides by 4</em>
x = -7
<h3>Answer: (-7, -46)</h3>
Answer:
138
Step-by-step explanation:
c=5
d=4
6c^2-5d+8
substitute c & d
6(5)^2-5(4)+8
6(25)-20+8
150-20+8 = 138
Use the pythagoras theorem to find the number of blocks between Shakillah's and Reyna's house
= sqrt (12^2+ 5^2) = aqrt 169 = 13 blocks
distanc,e from school to Shaquilla's house = 12 - 0 = 12 blocks
.. .. .. .. .. ... .. Reyna's house = 5 -0 = 5 blocks
So total number of blocks in entire trip = 5 + 12 + 13 = 30
Answer:
The area is 21 inches
Step-by-step explanation:
3x3=9
3x2=6
9+6=15 ( inches in the white box )
6x6=36 ( area of the whole box)
36-15= 21 ( inches in the shaded area )
