Answer:
86 °F = 30 °C
Step-by-step explanation:
Put the given number in the equation and solve for C.
86 = 9/5C +32
54 = 9/5C
(5/9)54 = C = 30
The equivalent is 30 degrees Celsius.
Answer:
m<2 = 57
Step-by-step explanation:
Since they are all in a straight line, the sum of the three angles = 180
Let m ∠3 = x
Thus;
2m<1 = x - 6
m<1 = (x-6)/2
m<2 = x-27
Adding all
x + x-27 + (x-6)/2 = 180
Multiply through by 2
2x + 2x -54 + x -6 = 360
5x -60 = 360
5x = 360 + 60
5x = 420
x = 420/5
x = 84
But m<2 = x -27
m<2 = 84 -27 = 57
Given:
The inequality is

To find:
The solution of the given inequality.
Solution:
We have,

Isolate the variables terms on the left side.


Divide both sides by -5 and change the inequality sign as we divide the equality by a negative value.


Therefore, the correct option is D.
Answer:
see below
Step-by-step explanation:
To graph this equation, start at the origin (0,0) since there is not y-intercept.
Because slope is characterized by rise/run ( i.e. how many units up or down depending on whether it is positive or negative and then however many units to the right.
Because the rise (up and down, numerator) is 1, we know that we will go up one unit.
The run (side to side, denominator) is 4, so we will go to the right 4 units.
This makes the first point (4, 1).
Continue doing this until you get an idea of the line and connect the points to get the graph
Answer:
A.
Step-by-step explanation:
-3x-7y = 10
In slope - intercept form
y = -3/7x - 10/7
Since the lines are parallel so the slopes will be equal
m = -3/7
Now
Point = (x,y) = (-5,-3)
So, x = -5, y = -3
Putting in slope intercept form to find b
y = mx+b
-3 = (-3/7)(-5) + b
-3 = 15/7 + b
7b = -21-15
7b = -36
b = -36/7
Now the slope intercept form for the line is
y = -3/7x-36/7
