<h3><u>The correct answer is: B.</u></h3>
We could use a graphing calculator to solve this easily, but let's just solve it by looking at the equation.
We'll need to turn this standard form equation into a slope-intercept form equation to be able to easily solve it.
Isolate y.
2x - 3y = 7
<em><u>Add 3y to both sides.</u></em>
2x = 3y + 7
<em><u>Subtract 7 from both sides.</u></em>
3y = 2x - 7
<em><u>Divide both sides by 3.</u></em>
y = 2/3x -7/3
Now, we can plug each x value in the answer choices into x to find the corresponding y value.
y = 2/3(7) - 7/3 = 2.34
As this y value does not match, A is not the answer.
y = 2/3(-4) - 7/3 = -5
This y value does match, so B is the correct answer.
y = 2/3(-9) - 7/3 = -8.34
This y value doesn't match either, so C is not the answer.
y = 2/3(9) - 7/3 = 3.67
This y value doesn't match either, so D is not the answer.
Answer:
t = -1
Step-by-step explanation:
8 + 9t - 3 + 4
Combine like terms
(8 - 3 + 4) + 9t
9 + 9t
9t + 9
Get <em>t</em> by itself
9t + 9 = 0
-9 -9
9t = -9
Divide both sides by 9 to find <em>t</em>
t = -1
Answer: s=a11-r (a1 = first term and r = common ratio)
Step-by-step explanation:
Answer:
x=12.124
Step-by-step explanation:
here 7 and x are the legs of the triangle where as 14 is hypotenuse because it is opposite opposite to 90 degree.
using pythagoras theorem
a^2 + b^2 = c^2
here and b are legs and c is hypotenuse
7^2 + x^2 = 14^2
49 + x^2 = 196
x^2 =196-49
x^2 =147
x=
x=12.1243
x=12.124 (after converting to the nearest hundredth)
