Answer:

-2/9

Step-by-step explanation:

The slope is found by

m= (y2-y1)/(x2-x1)

   = (-12- -14)/(3-12)

    =(-12+14)/(3-12)

    =2/-9

   = -2/9

A and B are sumplimenteey . m B =121 find m A
vichka [17]

Answer:

m∠A = 59°

Step-by-step explanation:

Supplementary angles mean that, when the two are combined, their total measurement will equal 180°.

It is given that one of the angles is 121°. Subtract 121 from 180:

180 - 121 = 59

m∠A = 59°

Solve by substitution y=2x-1 y=3x+1
kupik [55]
Answer: x = -2

Step-by-Step Explanation:

Since the two expressions both equal y, you can set them equal to each other.

2x-1 = 3x+1

Subtract 2x from both sides.

-1 = x+1

Subtract 1 from both sides.

-2 = x

Can someone plz help me with Algebra 2....... :) Will give Brainliest!!
Anarel [89]
Using logarithms property of log(x)+log(y)=log(xy)
so here, you can sum the equation to;
log((x+6)*(x-6))=2
so you can simply say that;
log_{8}((x+6)( x-6))=2
and by multiplying (x+6)*(x-6)
log_{8}(x^2-36)=2
and as you know also that;
a^{b}=c is same as log _{a}c=b
so you can simply state it as;
8^2=x^2-36&#10;64=x^2-36&#10;64+36=x^2&#10;x^2=100&#10;x=10
And you can check your work by substituting with 10 instead of x in the original function.
Hope this helps!

At midnight, the temperature was -8oF. At noon, the temperature was 23oF. Which expression represents the increase in temperatur
irinina [24]

Answer:

23^oF-(-8^oF)

Step-by-step explanation:

We have been given that at midnight, the temperature was -8^oF. At noon, the temperature was 23^oF.

Since our temperature has increased to 23 degree Fahrenheit from -8 degree Fahrenheit, we can represent this increase in temperature as:

\text{The increase in temperature}=23^oF-(-8^oF)

Therefore, the expression 23^oF-(-8^oF) represents the increase in temperature.
