Answer:

13) x = 30

14) x = 22.5

15) x = 36

Step-by-step explanation:

13) 4x+2x = 180

6x = 180

x = 30

14) 3x+5x = 180

8x = 180

x = 22.5

15) 2x+3x+2x+3x = 360

10x = 360

x = 36

What is the solution to the system of equations y= -5x + 30 x = 10
Arturiano [62]

Answer:

We have been given the equation:

y=-5x+30

And x=10

Substitute the given x in the given equation we get:

y=-5(10)+30

y=-50+30

On simplification we get:

y=-20

Required solution is:  x= 10 and y=-20

The solution to the system of equation is those points that satisfy the given system of equations.

What is the 6th term of the geometric sequence where a1 = -4096 and a4 = 64?
Akimi4 [234]
\bf \begin{array}{llccll}
term&value\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
a_1&-4096\\
a_2&-4096r\\
a_3&-4096rr\\
a_4&-4096rrr\\
&-4096r^3\\
&64
\end{array}\implies -4096r^3=64
\\\\\\
r^3=\cfrac{64}{-4096}\implies r^3=-\cfrac{1}{64}\implies r=\sqrt[3]{-\cfrac{1}{64}}
\\\\\\
r=\cfrac{\sqrt[3]{-1}}{\sqrt[3]{64}}\implies \boxed{r=\cfrac{-1}{4}}\\\\
-------------------------------

\bf n^{th}\textit{ term of a geometric sequence}\\\\
a_n=a_1\cdot r^{n-1}\qquad 
\begin{cases}
n=n^{th}\ term\\
a_1=\textit{first term's value}\\
r=\textit{common ratio}\\
----------\\
r=-\frac{1}{4}\\
a_1=-4096\\
n=6
\end{cases}
\\\\\\
a_6=-4096\left( -\frac{1}{4} \right)^{6-1}\implies a_6=-4^6\left( -\frac{1}{4} \right)^5

Need help on this please this one is hard for me
pshichka [43]

9514 1404 393

Answer:

  y = -7x

Step-by-step explanation:

The line goes through the origin, so the y-intercept is b=0.

The line goes through the point (1, -7), so has a "rise" of -7 for a "run" of 1. The slope is ...

  m = rise/run = -7/1 = -7

Then the slope-intercept form equation is ...

  y = mx + b

  y = -7x
