Answer: X = 34

Step-by-step explanation:

Let's solve your equation step-by-step.

x+30=2x−4

Step 1: Subtract 2x from both sides.

x+30−2x=2x−4−2x

−x+30=−4

Step 2: Subtract 30 from both sides.

−x+30−30=−4−30

−x=−34

Step 3: Divide both sides by -1.

−x

−1

=

−34

JulijaS [17]

Answer:

The drone takes 2.25 seconds to be higher than the basketball.

Step-by-step explanation:

Based on the definitions given on statement and the image attached below, the red line represents the height of the basketball and the blue line represents the height of the drone, respectively. The height of the drone is higher than the height of the basketball when the y-value of the former is higher than the y-value of the latter. The time is contained in the +x semiaxis.

According to the figure, the drone takes 2.25 seconds to be higher than the basketball.

Which ordered pair maximizes the objective function p = 3x 8y? (0, 0) (2, 7) (5, 6) (8, 1)
Degger [83]

The ordered pair maximizes the objective function p = 3x + 8y will be (5, 6) .Option C is correct.

<h3>What is the objective function?</h3>

The objective function is simply an equation that represents the goal production capability that relates to maximizing profits in relation to manufacturing.

On putting the values we will get the values one by one. We get;

1. (0, 0)

3 (0)+8(0) = 0

2. (2,7)

3(2)+8(7)=62

3. (5,6)

3(5)+8(6)=63

4. (8,1)

3(8)+8(1)=42

The maximum value obtained from the 63. Obtained from option C. The ordered pair maximizes the objective function p = 3x + 8y will be (5, 6)

Hence option C is correct.

What value of k makes the equation true? (5a^2 b^3)(6a^k b)=30a^6 b^4
Ratling [72]

we are given

(5a^2 b^3)(6a^k b)=30a^6 b^4

Firstly, we will simplify left side

and then we can solve for k

Left side is

(5a^2 b^3)(6a^k b)

we can arrange like terms

(5a^2 6a^k)(b^3 b)

(5\times 6 a^2a^k)(b^3 b)

(30 a^2a^k)(b^3 b^1)

now, we can use property of exponent

a^m \times a^n=a^{m+n}

(30 a^{2+k})(b^{3+1})

30a^{2+k}b^{4}

now, we can equate it with right side

and we get

30a^{2+k}b^{4}=30a^6 b^4

We can see that both sides have 30 , a and b

and they are equal

so, exponent of a must also be equal

2+k=6

now, we can solve for k

2+k-2=6-2
