Find the value of x. 3x(5+2)=16

Mathematics

Iteru [2.4K]4 years ago

Answer:

16/21

Step-by-step explanation:

We are given the equation 3x(5 + 2) = 16.

By order of operations, let's add the two numbers in the parentheses first:

3x(5 + 2) = 16

3x(7) = 16

Now, we must multiply 3x by 7:

3x * 7 = 16

21x = 16

Divide both sides by 21:

x = 16/21

The answer is thus 16/21.

Answer: x=0.8

Step-by-step explanation:

Distribute

3x*5=15x

3x*2=6x

15x+6x=21x

21x=16

divide 21 on both sides

x=0.76

round

x=0.8

Find the horizontal and vertical intercepts for
allsm [11]

Here, we are required to find the vertical and horizontal intercepts for r⁴ + s² − r s = 16.

The vertical and horizontal intercepts are s = ±4 and r = ±2 respectively.

According to the question;

  • the r-axis is the horizontal axis.
  • the s-axis is the vertical axis.

Therefore, to get the horizontal intercepts, r we set the vertical axis, s to zero(0).

  • i.e s = 0
  • the equation r⁴ + s² − r s = 16, then becomes;
  • r⁴ = 16
  • Therefore, r = ±2.

Also, to to get the vertical intercepts, s we set the horizontal axis, r to zero(0).

  • i.e r = 0.
  • the equation r⁴ + s² − r s = 16, then becomes;
  • s² = 16.
  • Therefore, s = ±4.

Therefore, the vertical and horizontal intercepts are s = ±4 and r = ±2 respectively.

PLEAAASE HELPP that would be very much appreciated
DIA [1.3K]

Answer:

h(x) = (x + 4)^2 - 2

Step-by-step explanation:

Start with the red graph:  f(x) = x^2

First we move the entire graph 4 units to the left.  The resultant function is g(x) = (x + 4)^2.

Next, we move this latest graph 2 units down.  The resultant function (and answer to this question) is h(x) = (x + 4)^2 - 2
