If h(x) = 5x − 3 and j(x) = −2x, solve h[j(2)] and select the correct answer below. (1 point) 17 23 −17 −23

Given h(x)=5x-3 and j(x)=-2x.

So, j(2) = -2*2 = -4

So, h[j(2)] =  h(-4)= (5*-4) -3 = -20-3 = -23

Hence option D is correct.

Find the value of x when : 2^30/8^9=2^x
artcher [175]

Answer:

x = -3

Step-by-step explanation:

Okay, the first thing to do is get that 8 away from the fraction. How can we do it? When you have 2³ you have 8, is the same thing, so let's do it:

2³⁰/(2³)⁹ = 2^x

When you have a number with the shape (a^x)^y, you can write it as a^(x•y), so:

(2³)⁹ = 2^3•9 = 2²⁷

Now we have:

2³⁰/2²⁷ = 2^x

When you have a division like this: (a^x)/(a^y), you can write it as a^(x-y), so:

2^(30-27) = 2^x

2^-3 = 2^x

Now you know that x = -3

Find the square root of the following using division method . iv) 36360
sveticcg [70]

Answer:

190.684

Step-by-step explanation:

To find the square root of 36360, we place a bar over the numbers that we want to find their square root in pairs

    ,    1       \dot{3} \overline{63}  \overline{60}

       , 1       1

2,       <u>9</u>      2  \overline{63}

         9      261  

38,      <u>0</u>            2 60

          0            0

         .    

380,    6            26000

        ,  6           22800

3806,  8          320000

         ,  8          304480

38068, 4       1552000

           ,4

Which gives 190.684

3             63 60

We select the divisor to be the largest number which when squares will be equal to the largest number on the left which is 1

We have 1 * 1 = 1

We subtract it from the 3 to get 2

We add the 1's to get 2

We bring down the next pair which is 63 to form the next dividend, 263

We look for a number which will multiply itself to get 263, which is 9, we then have 29 × 9 = 261

We continue till we arrive at the vertical paired numbers which is 190.684.

Five times the sum of a number and 3 is the same as 3 multiplied by 1 less than twice the number ​
Aneli [31]

Answer:-2

Step-by-step explanation:

(n + 3) 5 = 3 x 1 - n

distribute so 5n + 15= 3 - n

subtract three from both sides

5n - 12 = -n

subtract 5n from both sides

12 = −6n

Divide both sides by -6

n=-2

Which of the following relations is NOT a function?
topjm [15]
According to Wikipedia: "<span>In mathematics, a function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output."

So based of this we need to look for a set where one of the x values or the y values is the same, and the other number is different.

Answer:
B.
(1,4) and (1,1) both have the same x, but different y!
