Answer: 15
Step-by-step explanation:
5 = 15
6 = 18
3* the number so 3 * 5 is 15
That would be 100,000....because 115,000 is closer to 100,000 then 200,000
Step-by-step explanation:
4. 3x+7=37, 3x=37-7=30 x=30÷3=10
5. 31=7x-11, 7x=31+11=42 x=42÷7=6
6. 11k-84=92, 11k=92+84=176 k=176÷11=16
7. 4r+13=57, 4r=57-13=44 r=44÷4=11
8. z÷4+16=21, z÷4=21-16=5 z=5×4=20
9. 7=t÷6-3, t÷6=7+3=10 t=10×6=60
Answer:
17
Step-by-step explanation:
Now it says the number is 68 less than 5 times a number. x=68. Thus the number will be 17.
Answer:
<h2>(g o f)(- 4) = 570</h2>
Step-by-step explanation:
f(x)=4x+5
g(x)=4x² - 5x - 3
To find (g o f)(-4) we must first find
(g o f )(x)
To find (g of f)(x) substitute f(x) into g(x)
That's
(g o f)(x) = 4(4x + 5)² - 5(4x - 5) - 3
= 4( 16x² + 40x + 25) - 20x + 25 - 3
= 64x² + 160x + 100 - 20x + 22
(g o f)(x) = 64x² + 140x + 122
To find (g o f)(- 4) substitute the value of x that's - 4 into (g o f)(x)
Thats
(g o f)(- 4) = 64(-4)² + 140(-4) + 122
= 64(16) - 576 + 122
= 1024 - 454
We have the final answer as
<h3>(g o f)(- 4) = 570</h3>
Hope this helps you
