Given that we have the slope and a point on the graph we can use the point slope formula to find the equation of the line.
Point-Slope Formula:
y−y1=m(x−x1), where m is the slope of the line and x1 and y1 are x and y coordinates of a given point
Solve the system by substitution.
-9y - 10 = x
5x+ 6y = -11
Step-by-step explanation:
-9y - 10 = x
x = -9y - 10
5x + 6y = -11
5(-9y - 10) + 6y = -11
-45y - 50 + 6y = -11
(-45 + 6)y = -11 + 50
-39y = 39
y = 39/-39
y = -1
x = -9y - 10
x = -9(-1) - 10
x = 9 - 10
x = -1
solve the system of equations.
y=x^2+x+5
y=x+1
A x=-2,-2
B no solution
C (-2,0) and (2,0)
D (-2,-1) and (2,3)
Step-by-step explanation:
y = x² + x + 5
y = x + 1
x² + x + 5 = x + 1
x² + 4 = 0
x² = -4
x = ±√-4 undefined
No solutions

I need help with this I don’t understand at all
Answer:
first, simplify the equation, 5x-8x is -3x. So 6-7x = -3x+10
now subtract 6 from both sides, -7x = -3x+4
now add 3x on both sides. -4x = 4. now divide 4/-4 is -1. Thus X=-1
Answer:
x=-1
Step-by-step explanation:
6 - 7x = 5x - 8x + 10
First move the variables (x) to one side:
6 - 7x = 5x - 8x + 10
+7x +7x
6 = 5x - 8x + 7x + 10
Subtract 10 from both sides:
6 = 5x - 8x + 7x + 10
-10 -10
-4 = 5x - 8x + 7x
Simplify:
4x = -4
Divide by 4 to isolate x:
4x = -4
÷4 ÷4
x=-1

Hello I need help At a certain temperature, the speed of sound in the air is 330 meters per second.
Which of the following expressions would convert this speed into kilometers per second?
Answer:
Firstly, we are told that the value we are supposed to convert is "330 meters per second." When we see the word "per," we know that the unit should be divided.
So, really, the value is:
[tex]330\ \frac{meters}{second}[/tex]
Which can be abbreviated to:
[tex]\frac{330\ m}{1\ sec}[/tex]
We can scratch off the last two answers because they involve an x, and that is not our given value.
We can also eliminate the second answer because we are supposed to convert to kilometers, which is abbreviated by "km."
So, the answer is A or:
[tex](\frac{330\ m}{1\ sec})(\frac{1\ km}{1000\ m})[/tex]
The equivalent expression is [tex](a)\ \frac{330m}{sec} \times \frac{1\ km}{1000\ m}[/tex]
SpeedSpeed is the rate of change of distance over time
The speed in meter per second is given as:
[tex]Speed =330m/sec[/tex]
Equivalent expressionTo convert from meters to kilometers, we simply multiply the distance by 0.001.
So, we have:
[tex]Speed =\frac{330m}{sec} \times 0.001[/tex]
Express 0.001 as 1/1000
[tex]Speed =\frac{330m}{sec} \times \frac{1}{1000}[/tex]
Rewrite as:
[tex]Speed =\frac{330m}{sec} \times \frac{1\ km}{1000\ m}[/tex]
Hence, the equivalent expression is [tex](a)\ \frac{330m}{sec} \times \frac{1\ km}{1000\ m}[/tex]

Use the given root to find the remaining root of the function. Root: x = - 3 Function: f(x) = x ^ 2 + x - 6
Answer:
x = 2
Step-by-step explanation:
Since we know one root is -3, we know one factor of the equation is (x+3)
From there we can use the factor we know to factor the rest of the equation:
x^2 + x - 6 = (x+3) * ?
Since know -6 is just 3 * -2 and since 3-2 is 1,
(x+3)(x-2) = x^2 + x - 6
From there,
x - 2 = 0
x = 2

A road running north to south crosses a road going east to west at the point P. Car A is driving north along the first road, and an airplane is flying east above the second road. At a particular time the car is 15 kilometers to the north of P and traveling at 60 km/hr, while the airplane is flying at speed 185 km/hr 10 kilometers east of P at an altitude of 2 km. How fast is the distance between the car and the airplane changing?
Answer:
D^2 = (x^2 + y^2) + z^2
and taking derivative of each term with respect to t or time, therefore:
2*D*dD/dt = 2*x*dx/dt + 2*y*dy/dt + 0 (since z is constant)
divide by 2 on both sides,
D*dD/dt = x*dx/dt + y*dy/dt
Need to solve for D at t =0, x (at t = 0) = 10 km, y (at t = 0) = 15 km
at t =0,
D^2 = c^2 + z^2 = (x^2 + y^2) + z^2 = 10^2 + 15^2 + 2^2 = 100 + 225 + 4 = 329
D = sqrt(329)
Therefore solving for dD/dt, which is the distance rate between the car and plane at t = 0
dD/dt = (x*dx/dt + y*dy/dt)/D = (10*190 + 15*60)/sqrt(329) = (1900 + 900)/sqrt(329)
= 2800/sqrt(329) = 154.4 km/hr

Answer:
[tex]1\frac{1}{2}[/tex]
Step-by-step explanation:
The first step to solving this problem is to convert these into improper fractions.
[tex]7\frac{2}{3} =\frac{21+2}{3}=\frac{23}{3}[/tex]
[tex]5\frac{1}{9} =\frac{45+1}{9}=\frac{46}{9}[/tex]
The second step is to determine the reciprocal of the second term.
Reciprocal of [tex]\frac{46}{9} =\frac{9}{46}[/tex]
The third step is to multiply the first term by the reciprocal of the second term.
[tex]\frac{23}{3}*\frac{9}{46}=\frac{207}{138}[/tex]
The fourth step is to reduce this fraction.
[tex]\frac{207}{138}=\frac{3(69)}{3(46)}=\frac{23(3)}{23(2)}=\frac{3}{2}=1\frac{1}{2}[/tex]
Answer:
1 1/2 or 3/2
Step-by-step explanation:
First you need to make your fractions improper.
7 times 3 + 2 = 23, so the fraction is 23/3
5 times 9 + 1 = 46, so the fraction is 46/9
Since this is division, flip the second fraction.
So instead of 46/9, it's now 9/46
Now you can multiply.
23/3 + 9/46 = 207/138
207/138 simplified is 3/2, or 1 1/2
