15. Identify the slope of the line below and state the equation of the line.

mamaluj [8]

Answer:

Slope: m = 0

Equation: y = 3

Step-by-step explanation:

The equation of a line has the following format:

$y = mx + b$

In which m is the slope.

We choose two points which the equation crosses.

I am going to choose (0,3) and (1,3)

(0,3)

When x = 0, y = 3. So

$y = mx + b$

$3 = 0m + b$

$b = 3$

(1,3)

When x = 1, y = 3. So

$y = mx + 3$

$3 = 1m + 3$

$m = 0$

Slope: m = 0

Equation: y = 3

Find the solution of the system of equations.<br> 15x – 4y = -50<br> 3x – 2y = –16

rusak2 [61]

Answer:

x=-2, y=5. (-2, 5).

Step-by-step explanation:

15x-4y=-50

3x-2y=-16

---------------

15x-4y=-50

-5(3x-2y)=-5(-16)

------------------------

15x-4y=-50

-15x+10y=80

-------------------

6y=30

y=30/6

y=5

3x-2(5)=-16

3x-10=-16

3x=-16+10

3x=-6

x=-6/3

x=-2

What’s the answer to the top question and steps how to solve?

Leviafan [203]

Answer:

-3.69

Step-by-step explanation:

Exponential equations can be solved by taking Ln (natural logarithm) of both sides. The rule we need to know is:

$Ln(a^b)=bLn(a)$

Now lets work out this problem:

$16^{2x+3}=13^{x-1}\\Ln(16^{2x+3})=Ln(13^{x-1})\\(2x+3)Ln(16)=(x-1)Ln(13)$

Using calculator, we take the values of Ln 16 and Ln 13 as:

Ln 16 = 2.7726

Ln 13 = 2.5649

Now, we can solve for x:

$(2x+3)Ln(16)=(x-1)Ln(13)\\(2x+3)2.7726=(x-1)2.5649\\5.5452x+8.3178=2.5649x-2.5649\\2.9803x=-10.8827\\x=-3.69$

x is -3.69 (rounded to 2 decimal places)

3x-2y=18<br> Solve for y

suter [353]

Now all you have to do is divide -3x by -2 and 18 by -2 which would be:

Y= 3/2x-9
