Answer:
y= -2/7x-7
Step-by-step explanation:
slope intercept form is just a fancy way of saying y=mx+b
x being your input, y your output, m your slope, and b your y intercept
you can use the slope to determine your equation will look something like: y=-2/7x+b. To find your y-intercept all you do is determine how much the point will increase or decrease so it is equal to (0, y). In this case it will increase by 14 on the x's (so x is equal to 0) and 14*-2/7. When you have determined your y-int and slope you can then plug them into the equation instead of the variables.

Inverse trig for this
So we are given adjacent and opposite legs for this part. So tangent is used except because we are finding angle(tan^-1 is used) tan^-1 is not 1/tan
tan^-1(56/47)
We get 49.993744 and so on
So rounded to the nearest degree, that is 50.

Step-by-step explanation:
Lucia is 5.5 feet tall. She is standing on the roof of a building that is 80 feet tall. She spots a fountain at ground level that she knows to be 122 feet away from the base of the building. What is the measure of the angle of depression formed by Lucia's horizontal line of sight and her line of sight to the fountain? Round your answer to the nearest degree.
Answers
Answer:
125°
Step-by-step explanation:
So we know that the total height is 85.5 (building height plus Lucia's height) and that the distance between Lucia and the fountain is 122ft away. As seen in the badly drawn picture below, the question asks us to solve for x, we can do this by first solving for y by using tangent to calculate its value which is the following
tan(y) = opposite / adjacent
tan(y) = 122 / 85.5
tan(y) = 1.4269
y = [tex]tan^{-1}[/tex](1.4269)
y = 54.97
Now that we have the value of y and we know that a straight line has a degree of 180, we can simply subtract the degree of y from 180 to get the degree of x
180 - 54.97 = 125.03
Answer:
about 35°
Step-by-step explanation:
tan^-1(85.5/122)
35.02352736°
=35°
Write the equation of a line that is perpendicular to y=2/7x +9 and that passes through the point (4,-6).
Answers
Answer:
[tex]y=-\frac{7}{2}x+8[/tex]
Step-by-step explanation:
Given the equation
[tex]y\:=\:\frac{2}{7}x+9[/tex]
comparing the equation with the slope-intercept form
[tex]y =mx+b[/tex]
Here,
m is the slope y is the interceptso the slope of the line is 2/7
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so
the slope of the perpendicular line will be: -7/2
Therefore, the point-slope form of the equation of the perpendicular line that goes through (4,-6) is:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
[tex]y-\left(-6\right)=\frac{-7}{2}\left(x-4\right)[/tex]
[tex]y+6=\frac{-7}{2}\left(x-4\right)[/tex]
[tex]y+6-6=\frac{-7}{2}\left(x-4\right)-6[/tex]
[tex]y=-\frac{7}{2}x+8[/tex]

Verona is solving the equation -3 + 4x = 9. In order to isolate the variable term using the addition property of equality, which number should she add to both sides of the equation?
–4
3
–3
4
Answers
Answer: 3
Step-by-step explanation:
-3 + 4x = 9
if u add 3 to 9, u get 12. 12 divided by 4 is 3
Add 3 to both sides of the equation to isolate the variable term. Therefore, option B is the correct answer.
The given equation is -3 + 4x = 9.
What is addition property of equality?The addition property of equality tells us that adding the same number to each side of an equation gives us an equivalent equation.
Now, add 3 on both sides.
That is, -3 + 4x +3= 9+3
⇒4x=12
⇒x=3
Therefore, option B is the correct answer.
