Answer:
All positive rational numbers greater than 50
Step-by-step explanation:
Since the delivery cost is fixed per trip, the cost incurred can be represented by the equation
y(x)=8x+50 so in case Tess wants only 1 tone, the cost will be y(x)=8(1)+50=58
Therefore, it's proper to conclude that all numbers in the possible range are positive rational numbers greater than 50
(A) <em>f(x)</em> = 7 is constant, so <em>f(x</em> + <em>h)</em> = 7, too, which makes <em>f(x</em> + <em>h)</em> - <em>f(x)</em> = 0. So <em>f'(x)</em> = 0.
(B) <em>f(x)</em> = 5<em>x</em> + 1 ==> <em>f(x</em> + <em>h)</em> = 5 (<em>x</em> + <em>h</em>) + 1 = 5<em>x</em> + 5<em>h</em> + 1
==> <em>f(x</em> + <em>h)</em> - <em>f(x)</em> = 5<em>h</em>
Then

(C) <em>f(x)</em> = <em>x</em> ² + 3 ==> <em>f(x</em> + <em>h)</em> = (<em>x</em> + <em>h</em>)² + 3 = <em>x</em> ² + 2<em>xh</em> + <em>h</em> ² + 3
==> <em>f(x</em> + <em>h)</em> - <em>f(x)</em> = 2<em>xh</em> + <em>h</em> ²

(D) <em>f(x)</em> = <em>x</em> ² +<em> </em>4<em>x</em> - 1 ==> <em>f(x</em> + <em>h)</em> = (<em>x</em> + <em>h</em>)² + 4 (<em>x</em> + <em>h</em>) - 1 = <em>x</em> ² + 2<em>xh</em> + <em>h</em> ² + 4<em>x</em> + 4<em>h</em> - 1
==> <em>f(x</em> + <em>h)</em> - <em>f(x)</em> = 2<em>xh</em> + <em>h</em> ² + 4<em>h</em>

Step-by-step explanation:
he gave 40% to his bro and spent 10% 40+10=50 so he spent 50%
Answer:
4 3/8
Step-by-step explanation:
1. We can use the formula
<em>Area = L (length) x W (width)</em>
2. The area is unknown so we can substitute it for<em> a</em>
<em> </em>The length and width are both known, so we can plug them in.
<em>a= 2 1/2 x 1 3/4</em>
3. Solve by multiplying
<em>a=4 3/8</em>
Answer:
The value of x is 27
because 2 times 27 equals 54 minus 7 equals 47
