Why are we unable to see x-rays?
btw I know this is not math but I put it as math because if I put it as physics no one would see it ;-;
Answer:
they're similar to visible light except their wave length is much shorter, causing them to be invisible to the naked eye
Answer:
We are unable to see x-rays because x-ray light it is too blue for us to see.
Step-by-step explanation:
Too much blue light can cause retina damage to the eye or eye strain. Their are kinds of lens that help protect you from blue light. There are good things about blue light but this is why we can't see x-rays.
I hope this helps!
if the answer to a system of equations is x = 4 y = 0, if you were to graph the solution at what point(X,Y) would you expect to see the two lines intersecting. Explain your answer.
Answer:
Step-by-step explanation:
We can find the solution to a system of equations by graphing the equations. Let's do this with the following systems of equations:
\goldD{y=\dfrac{1}{2}x+3}y=
2
1
x+3start color #e07d10, y, equals, start fraction, 1, divided by, 2, end fraction, x, plus, 3, end color #e07d10
\greenE{y=x+1}y=x+1start color #0d923f, y, equals, x, plus, 1, end color #0d923f
First, let's graph the first equation \goldD{y=\dfrac{1}{2}x+3}y=
2
1
x+3start color #e07d10, y, equals, start fraction, 1, divided by, 2, end fraction, x, plus, 3, end color #e07d10. Notice that the equation is already in yyy-intercept form so we can graph it by starting at the yyy-intercept of 333, and then going up 111 and to the right 222 from there.
Next, let's graph the second equation \greenE{y=x+1}y=x+1start color #0d923f, y, equals, x, plus, 1, end color #0d923f as well.

Answer:
baby has f pieces of candy then her friend gave her 5 more pieces and after she counted all her candy and she had 9 total pieces . how many pieces of candy was f ?
Please help with this question! Have attached a picture!!!
Answer:
The answer is E.
Step-by-step explanation:
Plug all the values into the inequalities.
For these, we need only one equation to be true for the x's to work.
When those x-values are plugged in to the first equation, they are less than 18, so this equation doesn't work with our values.
The second equation does work, as all the values are less than or equal to -4. That means that anything in between those number would work as well, so E has to be the correct answer.

Step-by-step explanation:
11) slope and y-intercept, if the answer ignore this if you do know the answer than plz answer
Answer:
Slope : -1
Y-intercept : (0,6)
Step-by-step explanation:
Answer:
Slope: -1
y-intercept: 6
Step-by-step explanation:
Lets figure out the slope with the formula, [tex]\frac{y2 - y1}{x2-x1}[/tex]. Take 2 coordinates and substitute them in. Lets take (-3,9) and (-1,7). Here are the steps:
[tex]\frac{7-9}{-1-(-3)}[/tex]
[tex]\frac{-2}{-1+3}[/tex]
[tex]\frac{-2}{2}[/tex]
[tex]-1[/tex]
Now we know that the slope is -1, so m = -1.
Lets figure out the y-intercept. We have to have an equation with the slope in it. Since we don't know the y-intercept yet, we will use the equation y = -x + b. Lets take the coordinate (5,1). Substitute the coordinates in. Here are the steps:
1 = -5 + b
b = 6
Now we know that the y-intercept is 6, so b = 6. I hope this helped!

heheheh I do math lol
Answer:
-8x^2+62y^2+46
Step-by-step explanation:
55x^ 2 + 62y^2 + 38 − 63X^ 2 + 8
Look at all variables that are similar and bring them next to each other
(55x^2 -63x^2)+(62y^2)+(38+8)
Add them together
-8x^2+62y^2+46
