Please help...Here's a graph of a linear function. Write the equation that describes that function
Answers
Answer:
y = 6x - 4
Step-by-step explanation:
Slope formula: y = mx + b
m = slope, found by figuring out the change in y over the change in x. A fancy way to say find the simplest rate of how far up it goes over how far right it goes. In this case, the line goes up 6 for every time it goes right one; 6/1. This can be simplified as 6.
b = y-intercept, meaning where the line crosses the y line. In this line, you can see that it crosses at -4.
Hope this helps!

solve the equation below for x when y= 290
Answers
Answer:
If y = 290, x = 30
Step-by-step explanation:
y = 200 + 3x If y = 290
290 = 200 + 3x
290 - 200 = 3x
90 = 3x
90/3 = x
30 = x

Find the input (x) of the function y = 3x - 7 if the output
(y) is 5.
Answers
Answer:
The input (x) = 4
Step-by-step explanation:
Since we know what the output (y) is, you can substitute it into the equation to get:
5 = 3x - 7
Then, solve for x, and you’ll get x = 4. The image below shows step-by-step on how to solve for x.

6x - 7 = 4x + 7
2x = 14
x = 7
Or you can also do supplementary angles

26x = 182
x = 7
The answer is x = 7

For a celebration a town is going to pass out miniature replicas of the town's
bell. The replicas are 9 in. tall. If the scale of the replica is l in. : 0.5 ft, how
tall is the actual bell?
Answers
Answer:
The bell is 4.5 feet tall
Step-by-step explanation:
The ratio of the replicas are 1in : 0.5ft, so each inch of the model is 0.5 feet in real life.
The replicas are 9 inches tall, so you would multiply by the scale factor, 0.5 feet. You want the units to end up being feet, so you position the fractions to cancel out inches.
[tex]\frac{9}{1}[/tex] in x [tex]\frac{0.5}{1}[/tex] [tex]\frac{ft}{in}[/tex]
the inches cancel out and you are left with:
9 x 0.5 ft
Simplify.
4.5 ft
A cylinder has a height of 7 feet and a radius of 12 feet. What is its volume? Use ≈ 3.14 and round your answer to the nearest hundredth.
Answers
Which equals 3165.1 (I believe)
Answer: 461.6 ft^3
Step-by-step explanation:
Substitute r and h into the volume formula. In this case, the height is 12, so h = 12. The diameter is 7, so the radius is half that, or 3.5. Substitute into the formula and simplify: V=π(3.5)2(12)V=π(12.25)(12)V=147π
So the exact volume of the cylinder is 147π ft3
.
To find the approximate volume, substitute 3.14 for π
and simplify:V≈147(3.14)≈461.58
. Rounded to the nearest tenth, the approximate volume of the cylinder is 461.6 ft3
.

suppose that when you factor 4t^6-r^10, you get (2t^x+r^y)(2t^x-r^y). determine the sum of t and r.
Answers
Answer:
8
Step-by-step explanation:
Given the expression
4t^6-r^10 we are to factorize in the form;
(2t^x+r^y)(2t^x-r^y)
First we need to factorize (2t^x+r^y)(2t^x-r^y)
[tex]= (2t^x+r^y)(2t^x-r^y)\\= 4t^{2x}-2t^xr^y + 2t^xr^y - r^{2y}\\= 4t^{2x}-r^{2y}[/tex]
Compare [tex]4t^{2x}-r^{2y} \ with \ 4t^6-r^{10}[/tex]
[tex]4t^{2x} = 4t^6\\t^{2x} = t^6\\equate \ the \ powers\\2x = 6\\x = 3\\[/tex]
Get y;
[tex]r^{2y} = r^{10}\\2y = 10\\y = 5\\Hence \ x + y = 3+5 = 8[/tex]
Hence the sum of x and y is 8
