Answer:
(A)The lines will have the same slope but different y-intercepts.
Step-by-step explanation:
If the system of equations had infinitely many solutions that must mean that they are the exact same graph. This means that the lines will have the same slope but different y-intercepts.
A scientist looks at a bacterium and a virus in a lab. The bacterium has a diameter of 10 Superscript negative 6 meters. The virus has a diameter of 10 Superscript negative 7 meters. Which statement accurately compares the sizes of the specimens?

13.two quantities ,x and y, vary directly, if x=5 and y=20, find y when x=45.
14.two quantities ,x and y, vary directly, if x=8 and y=48, find y when x=32.
Answer: 13. 180, 14. 192
Step-by-step explanation:
13.
What is the relationship of 5 and 20?
4x5 is 20.
That means y is 4 times more than x.
So, if you apply this to x= 45, what is y?
45x4 =180
This can be used as a ratio
5:20
45: ?
To get 5 to 45, multiply by 9
That means you have to equal out the equation by multiply 20 by 9, = 180.
14.
8: 48
32: ?
8x4 is 32
48x4=192
y= 192
Select the sets of angles that could be the interior angle measures of a triangle.
85°, 43°, and 52°
90°, 37°, and 51°
37°, 65°, and 78°
120°, 12°, and 40°
162°, 2°, and 16°
Answer:
85 43 and 52
37, 65, and 78
162 2 and 16
Step-by-step explanation:
It should add up to 180 because the degree for a square is 360 and a triangle is half of it.
Answer:
85 43 and 52
37, 65, and 78
162 2 and 16

Answer: x is less then 5 over 4. Open circle on 1.25 shading to the left on the number line.
Step-by-step explanation:
Step 1: 16x is less than 20
step 2: divide by 16, 16x over 16 is less than 20 over 16.
step 3: x is less than 5 over four (1.25)

Tell whether the angles are complementary or supplementary. Then find the value of x.
I don't know how to find the value of x T^T and If I see links your getting reported >:( I'm tired of them.
Answer:
The angles are complementary; X = 15
Step-by-step explanation:
When angles are complementary, they always add up to 90 degrees angles, which is a right angle. Supplementary angles add up to 180 degree angles, which is a straight line. When telling the difference, my math teacher taught me to remember the saying "complementing is always the right thing to do" (it's corny, I know, but it worked for me lol)
To find x, you would do 90 minus the other angle, which is 45, to get 45. Then, you would divide by 3, to get 15 as x.
Help me please, the question is in the picture! :))

slope intercept form is y = mx + b.
the m represents slope and the b represents the y-intercept.
therefore, the answer to your problem would be: y = -1/7x - 8/7

Answer:
y=2x-46
Step-by-step explanation:
Select any two coordinate points. I'm picking (1,-44) and (2, -42).
x1 and y1 are the first coordinates. x2 and y2 are the second coordinates. The formula for finding the slope of a linear fuction is (y2-y1)/(x2-x1). Substiute the numbers into this formula:
-42-(-44)/2-1
=-42+44/1
=2
This is the slope. In y=mx+b, plug in your newly found slope. Next, to find the y-intercept, plug any pair of coordinate points into your incomplete formula y=2x+b. I'm going to use (1,-44) again.
-44=2(1)+b
-44=2+b
b=-46
Now, plug this into your formula, and you'll get y=2x-46.
