The equivalent value of the function f(x) = –2x^2 – 3x + 5 if x = -3 is -4

We are to evaluate the function f(x) = –2x2 – 3x + 5 for the input value –3.

Given the function:

  • f(x) = –2x^2 – 3x + 5

For x = -3, we will have to substitute x = -3 into the expression to have:

f(-3) = –2(-3)^2 – 3(-3) + 5

f(-3) = -2(9) + 9 + 5

f(-3) = -18 + 14

f(-3) = -4

Hence the equivalent value of the function f(x) = –2x^2 – 3x + 5 if x = -3 is -4

Find the larger of two consecutive integers if the larger is 149 less than twice the smaller.
snow_tiger [21]

Answer:

151

Step-by-step explanation:

Let x = the smaller integer and y = the larger integer.

We have two conditions:

(1)   x + 1 = y

(2)       y =  2x - 149      Substitute (1) into (2)

    x + 1 = 2x - 149        Add 150 to each side

x + 150 = 2x                 Subtract x from each side

        x = 150                Substitute into (1)

150 +1 = y

       y = 151

The larger integer is 151.

<em>Check: </em>

(1) 150 + 1 = 151

          151 = 151

(2)       151 = 2×150 -149

          151 = 300 -149

          151 = 151

A rectangular garden covers 16,000 ft2. Its length is 60 ft longer than its width.
tatiyna
The width is x 
<span>The length is x+60 </span>

<span>so x(x+60) = 16000 
</span>
<span>x^2 + 60x = 16000 
</span>
<span> </span>
<span>x^2 + 60x + 900 = 900+16000 
</span>
<span>(x+30)^2 = 16900
 </span><span> </span>
<span>x+30 = 130
 </span>
<span>x = 100

So your answer is 100. </span>

Which is the solution of x/5 -10 =20 ?
andreyandreev [35.5K]

Add 10 to both sides

x/5 = 2 + 10

Simplify 20 + 10 to 30

x/5 = 30

Multiply both sides by 5

x = 30 × 5

Simplify 30 × 5 to 150

<u>x = 150</u>
