triangle TCL is similar to triangle AEN. solve for x and y
Answer:
y = 6.7
x = 8
Step-by-step explanation:
3^2 + 6*2 = y
√9 + 36 = y
6.7 = y
10^2 = 6^2 + x
100 = 36 + x
100 (-36) = 36 (-36) +x
√64 = x
8 = x

so
2.25 pound cost #8
1 pound will cost x
cross multiply
x=8/2.25
x=$3.55 for one pound.
step two:
Hence if 1 pound cost $3.55
4 pound will cost = 3.55*4= $14.22

Answer: -3 bc the exponent is adding -1 each time
Answer: -3 for the exponent box
Step-by-step explanation: Hi there! Let's get started.
We know that a negative exponent is going to decrease by a power of 10 every time for example 10 x 10^-1 = 1 because the -1 says we need to move the decimal point one to the left.
So with this we take 2.345 x 10^-3 = 0.002345.
We moved the decimal point 3 to the left from 2.345 to get 0.002345.
Hope this helps! :)

17 What are the x-intercept to the function f(x)=2x-31+2 ?
A {0}
B{-5/2,5/2}. C{ } D{-5/2,-1/2}
Answer:
See below
Step-by-step explanation:
It seems to be a typo.
[tex]f(x)=2x-31+2[/tex]
[tex]f(x)=2x-29[/tex]
The x-intercept is when the function is equal to zero. Once the function is linear, there will be one x-intercept.
[tex]0=2x-29[/tex]
[tex]x=\dfrac{29}{2}[/tex]
Once there are alternatives with two values, your function is probably a quadratic function.
[tex]f(x)=2x^2-31x+2[/tex], but the roots are not in the alternatives.
This equation shows how the length of Rob's essay depends on the number of hours he spends writing this week. p = h + 11 The variable h represents the number of hours he spends writing this week, and the variable p represents the total number of pages that have been written. How many hours will Rob have to spend writing this week in order to have written a total of 16 pages?
Answer:
Rob will have to spend 5 hours writing this week in order to have written a total of 16 pages.
Step-by-step explanation:
From the information given, you can use the formula p=h+11 and solve for h. Then, you have to replace p with 16 to get the amount of hours that Rob will have to spend writing this week in order to have written a total of 16 pages:
p=h+11
h=p-11
h=16-11
h=5
According to this, the answer is that Rob will have to spend 5 hours writing this week in order to have written a total of 16 pages.

Answer:
y = -1/4x-6
Step-by-step explanation:
y=mx+b
Use slope equation m = (y1 - y2) / (x1 - x2)
b is the y intercept : -6
Answer:
y=-1/4x+(-6)
Step-by-step explanation:
Slope intercept form is y=mx+b. To find the slope, pick 2 points the line crosses through and divide the rise by the run. You can see the y-intercept on the graph. Therefore the equation should be y=-1/4x+(-6).
