What multiplies to 42 and adds to -27

1 answer:

5 0

Consider ways to multiply to get 42. Then see if the numbers can be used to make -27.

42 = 21 × 2...not going to work.
42 = 14 × 3...not going to work. (Though -14 and -3 add to -<em>17</em>)
42 = 7 × 6...not going to work.

There are no whole number solutions to this question.

If h(-8), find 1/3*h(x) = x^2-5x+7

Lynna [10]

The value is 333

<h3>How to determine the function</h3>

From the information given, we have:

x = - 8
1/3*h(x) = x^2-5x+7

Now, let's substitute the value of 'x' in the function:

1/3*h(x) = x^2-5x+7

1/ 3 × h(-8) = ( - 8)² - 5 ( -8) + 7

Make 'h ( -8)' the subject of formula

h ( -8) = $\frac{( -8)^2 - 5(-8) + 7}{1/ 3}$

h ( -8) = $\frac{64 + 40+ 7 }{1/ 3}$

Take the sum of the numerator

h ( -8) = $\frac{111}{1/3}$

Take the inverse of the denominator and multiply

h ( -8) = 111 × 3/ 1

h ( -8) = 333

We can see that through the substitute of the value of x as - 8, we get 333

Thus, the value is 333

a repair bill for your car is 553. the parts cost 265. the labor cost is 48 per hour write and solve an equation to find the num

Effectus [21]

Let's represent the number of hours with the variable 'h' (or whatever letter you want it to be):

265 + 48h = 553

Substract both sides by 265:

48h = 288

Divide:

h = 6

6 hours of labor was spent

line k has a slope of -5. line j is perpendicular to line k and passes though the point (5,9) create the equation for line j

Anna71 [15]

Answer:

y = 1/5x + 8

Step-by-step explanation:

The first thing you should know is that the slope of a perpendicular line is the opposite reciprocal. So, the slope of line j is 1/5. This is your current equation: y=1/5x + b. Plug in your coordinate to the equation, it should look like this: 9=1/5(5)+ b. 1/5 times 5 equals 1, so this is what it should look like: 9=1 + b. Subtract 1 from both sides to get 8 = b. Go back to your original equation and plug in 8 to b. This is your final equation: y = 1/5x + 8. Hope this helped!
