How to do the problem

trapecia [35]

Step-by-step explanation:

$g(0.5) = 2 \\ \\ h(x) = g(x).f(x) \\ \therefore \: h(2) = g(2).f(2) \\ \therefore \: h(2) = 5 \times 2\\ \therefore \: h(2) = 10\\ \\ \\ j(x) = g(x) - f(x) \\ \therefore \: j(4) = g(4) - f(4) \\ \therefore \: j(4) = 9 - 8\\ \therefore \: j(4) = 1\\ \\ \\$

If w = 2, x = 3, y = 5, and z = 6 then evaluate the expression: z/2

galina1969 [7]

Answer:

Step-by-step explanation:

To evaluate the expression, we have to substitute the variable in the expression, z, for its stated value. Given that z = 6, substitute 6 for the z in the expression and solve:

$\frac{z}{2} \\= \frac{6}{2} \\= 3$

Thus, the answer is 3.

What is 238 rounded to the nesrest ten

Solnce55 [7]

238 rounded to the nearest ten would be 240 because 8 is bigger than 5. So since its bigger we move the tens place (3) a number ahead (4).

Thats how we get 238 rounded to the nearest ten would be 240.

Hope I helped ya!!

What are the solutions of the quadratic equation x2=9x+6

irina [24]

Question: What is the solution to the equation $\bold{x\cdot \:2=9x+6}$

Answer: $\boxed{\bold{x=-\frac{6}{7}}}$

Explanation: $\downarrow{\downarrow{\downarrow{}}}$

[ Step One] Subtract 9x From Both Sides Of Equation

$\bold{x\cdot \:2-9x=9x+6-9x}$

[ Step Two ] Simplify Equation

$\bold{-7x=6}$

[ Step Three ] Divide Both Sides By -7

$\bold{\frac{-7x}{-7}=\frac{6}{-7}}$

[ Step Four ] Simplify

$\bold{x=-\frac{6}{7}}$

$\bold{\rightarrow{}Rhythm \ Bot\leftarrow{}}$

A car passes a landmark on a highway traveling at a constant rate of 40 kilometers per hour. Two hours later, a second car passe

Ratling [72]

So first you want to find how much the second car gains on the first car in one hour.

Since the second car travels 65 kph, but the first travels 40, we can just subtract 40 from 65 to find how much faster the second car is than the first.

65 - 40 = 25

So the second car is 25 kph faster than the first.

Since the first car had a 2 hour head start, we first want to calculate how far away the first car got from the sign before the second car reached the sign.

So just 2 hours * 40 kph, which gives you 80 kilometers.

So now we know the second car has to gain 80 km on the first car in order to overtake it.

Since the second car gains 25 km per hour on the first car, we can just divide 80 by 25.

80 / 25 = 16/5, or in decimal form 3.2.

So the second car will overtake the first car in 3.2 hours, or 192 minutes, which is also 3 hours and 12 minutes.
