A line has a y-intercept and a slope of 0. What is the line’s equation?
Gnom [1K]
The answer is y= -1

When the slope is 0, we refer to the line as a constant function. In slope intercept form, the line is equal to y = mx + b

 

"m" is the slope, and "b" is the y-intercept.

 

Let's replace those in the function.

 

y = 0*x - 1

 

0 multiplied by anything is 0

 

y = 0 - 1

y = -1

Do you know how to solve this?
Nataly_w [17]

Answer:

x=11

Step-by-step explanation:

The sum of all the angles in a triangle is always 180 degrees.

Hence,

(7x-17)+42+78=180

Remove the brackets:

7x-17+42+78=180

Add/Subtract the numbers:

7x+103=180

Subtract 103 from both sides:

7x+103-103=180-103

7x=77

Divide both sides by 7:

\frac{7x}{7}=\frac{77}{7}

x=11

timofeeve [1]
Check the picture below, so it hits the ground when h = 0, therefore,

\bf \stackrel{h}{0}=160-12t-16t^2\implies 16t^2+12t-160=0\\\\\\ 4t^2+3t-40=0
\\\\\\
\textit{now let's use the quadratic formula}
\\\\\\
~~~~~~~~~~~~\textit{quadratic formula}
\\\\
\begin{array}{lcccl}
y=& 4 t^2& +3 t& -40\\
&\uparrow &\uparrow &\uparrow \\
&a&b&c
\end{array} 
\qquad \qquad 
t= \cfrac{ -  b \pm \sqrt {  b^2 -4 a c}}{2 a}

\bf t=\cfrac{-3\pm\sqrt{3^2-4(4)(-40)}}{2(4)}\implies t=\cfrac{-3\pm\sqrt{9+640}}{8}
\\\\\\
t=
\begin{cases}
\frac{-3+\sqrt{649}}{8}\\\\
\frac{-3-\sqrt{649}}{8}

\begin{cases}
\boxed{2.81}\\\\
-3.56
