The sum of 38 and twice a number x is 124. The value of "x" is 43
- 2x - 5 is equal to – 91.
<u>Solution:</u>
Given that , The sum of 38 and twice a number x is 124.
We have to find what is - 2x - 5?
Now, according to given information, 38 + 2 × x = 124
2x + 38 = 124
2x = 124 – 38
2x = 86
x = 43
So, the value of x is 43
<em><u>Now, Evaluating - 2x – 5 </u></em>
Substitute "x" = 43 to evaluate
- 2(43) – 5
- 86 – 5 = - 91
Hence, the required answer is – 91.
Answer:
Hi, I think it's DEGF
Step-by-step explanation:
for y=x－2,
just move y=x down 2 units.
for x=－2,
it's the easiest one, just see if there is a vertical crossing －2 on the x-axis.
for－2x+4,
you can see it as move y=－2x up 4 units, and for y=－2x, you can find it out by sub (1,-2) and (0,0) onto the graph.
for x²-4,
see it as y=x² moved down 4 units. for y=x², it's simply a parabola which is symmetrical along y-axis and crossing (0,0). And remember that since the coefficient of x² is positive, the graph is open upward.
Hope this will help u!!
