Answer:
x = 7
Step-by-step explanation:
3x - 17 = 25 - 3x
Get the x's on one side and the integers on the other
3x + 3x = 25 + 17
6x = 42
x = 7
Answer:
(4x2 + 1) • (5x - 3)
Step-by-step explanation:
We need to add 1.45 x 10^8 and 3.9 x 10^7.
Please see..
We have given numbers in scientific form.
<em>We can't add the decimal numbers in front, because those numbers are being multiplied with 10 exponents and the exponents of 10's are not same.</em>
<em>So, we always convert the exponents of 10 as same.</em>
<em>1.45 x 10^8 could be converted to 14.5 x 10^7 to get exponent of 10 as 7 as other number 3.9 x 10^7 also has exponent of 10 as 7.</em>
<em>After this step we can just add the 14.5 and 3.9 and put × 10^7 with it.</em>
So, first correct step is:
<h3>
2. Convert 1.45 x 108 to 14.5 x 107.</h3>
We are given mid-point (-11, 18).
One end point (-5, 10).
Let us take coordinate of other end points is (x,y).
Therefore,
Given mid point (-11, 18).
Therefore,
and
Multiplying both sides by 2 in both equations, we get
x-5 = -22 and y+10 =36.
x = -22+5 and y = 36-10
x = -17 and y = 26.
<h3>Therefore, corrdinates of other end point is (-17, 26).</h3>
