Answer:
x-intercept = 6.2 , y-intercept = 3.1
Step-by-step explanation:
First turn 2x + 4y = 12.4 to slope-intercept form (y = mx + b) where m is slope and b is y-intercept.
Subtract 2x on both sides to move it to the other side, and get 4y by its self. Now it looks like 4y = -2x + 12.4 (since 2x and 12.4 aren't like terms, you wouldn't combine them).
Next, divide 4 on both side to get rid of it, and to get y by its self. Now you'll have
y = -2/4 x + 3.1 (since 12.4 can be divided by 4, that's how you get 3.1). You can already tell, just by looking at
y = -2/4 x + 3.1 , that the y-intercept is 3.1
Now we graph, to find out what the x-intercept is. I did it for you above.⤴⤴⤴
Answer:
(x, y) = (-2, 7), (0, -1), (3, -13), (-1, 3)
Step-by-step explanation:
To fill in the y-values, you need to put the x-value in the equation and evaluate.
<u>for x=0</u>
y = -4(0) -1 = -1
<u>for x=-1</u>
y = -4(-1) -1 = 4 -1 = 3
__
To fill in the x-values, we can solve for x and then do as we did above.
y = -4x -1
y +1 = -4x . . . . add 1
-(y +1)/4 = x . . . divide by -4
<u>for y=7</u>
x = -(7 +1)/4 = -2
<u>for y=-13</u>
x = -(-13+1)/4 = -(-12/4) = 3
__
Then the table is ...
(1, 3 )
to determine if the given points are a solution to the equation
They must lie on the given line to be a solution
the only one that is on the line is (1, 3 ) and is therefore the only solution
By applying the Tan trigonometric formula, the value of the tangent for angle A is equal to: A. 3√91/91.
<h3>How to find the value of the tangent for <A?</h3>
In order to determine the value of the tangent for <A, we would apply Pythagorean theorem:
AB² = AC² + BC²
40² = AC² + 12²
AC² = 1600 - 144
AC = √1456
AC = 4√91 in.
Now, we can determine the value of the tangent for <A by applying the Tan trigonometric formula:
TanA = Opp/Adj
TanA = BC/AC
TanA = 12/4√91
TanA = 3√91/91.
