Answer:
f(9/2) = 17/2
Step-by-step explanation:
f(x) = 3x-5
let x=9/2
f(9/2) = 3*9/2 -5
f(9/2) = 27/2 - 5
get a common denominator
f(9/2) = 27/2 - 10/2
f(9/2) = 17/2
1. count how many sig figs are in the number with least sig figs
2. multiply
3. cut the result off at the number of sig figs on top
15.05 has 4 sig figs
341.2
C
Answer:
24x+18y = 1
Step-by-step explanation:
any linear equation with 2 variables will have a virtually infinite amount of solutions
Hope this helps :)
Answer:
<h2>x = 54</h2>
Step-by-step explanation:
The line is tangent. Therefore, the angle between the tangent and the radius is the right angle.
We know: the sum of the angles measures in a triangle is 180°.
Therefore we have the equation:
<em>combine like terms</em>
<em>subtract 126 from both sides</em>

Answer:






Step-by-step explanation:
step 1
Find the value of x
we know that
----> by alternate interior angles
solve for x
Group terms


step 2
Find the measure of angle a
we know that
----> by vertical angles
substitute the value of x

step 3
Find the measure of angle b
we know that
----> by supplementary angles (form a linear pair)
we have

substitute


step 4
Find the measure of angle c
we know that
----> by vertical angles
we have

therefore

step 5
Find the measure of angle d
we know that
----> by corresponding angles
we have

therefore

step 6
Find the measure of angle e
we know that
----> by alternate exterior angles
we have

therefore

step 7
Find the measure of angle f
we know that
----> by vertical angles
we have

therefore
