Answer: 2
33 degrees C
Step-by-step explanation:
On the integer scale, the numeric values can be added thus
23 to -10
23 to 0 and 0 to -10
23-0 = 23
0 -(-10) = 10
23 + 10 = 33
Thus, 33 degree C is the difference between the two temperatures.
Answer is 36.
First use the negative exponent rule. When a number is put to the negative power it becomes a fraction
4/3^2
Now 3 to the second power is 9
4/1/9 (4 over 1/9)
Now multiply 4 x 9 (dividing by 1/9 is the same as multiplying by 9)
4 x 9= 36
Answer:
2. y = 7/2 x -2
3. y = 3/4x-1
Step-by-step explanation:
points (0,-2) (4,12)
slope = (y2-y1)/(x2-x1)
slope = (12--2)/(4-0)
= (12+2)/4
= 14/4 = 7/2
the slope is 7/2 and the y intercept is -2
y = mx+b
y = 7/2 x -2
points (0,-1) (4,2)
slope = (y2-y1)/(x2-x1)
slope = (2--1)/(4-0)
= (2+1)/4
= 3/4
the slope is 3/4 and the y intercept is -1
y = mx+b
y = 3/4x-1
