t = -3 (combine like terms)</span>
Answer: slope is -3 and y-intercept is -2
Step-by-step explanation:
when x= 0, y=-2
when x=1, y=-5
i believe you have just to change the value of the letter x in the equation to find the value of y
Answer and explanation:
Temperature:
If it was -5°C, you know that it is very cold and below freezing point (0°C), but if it was 20°C you know the weather is quite warm.
0°C is freezing point and is used as a reference point to be able to tell if the temperature is warm or not.
Answer:
1. C)
2. D)
Step-by-step explanation:
We know that:
1/3 is afraid of spiders
1/12 fears spiders and snakes
Then, the proportion of children who fear spiders and also snakes is calculated as:
Option C)
Of the 1/3 of children who fear spiders, 1/4 of them also fear snakes.
Now:
1/2 is afraid of the serientes
1/12 fears spiders and snakes
Then, the proportion of children who fear spiders and also snakes is calculated as:
Option D)
Of the 1/2 of children who fear snakes, 1/6 of them also fear spiders
Answer:
The slope is 9/8, and the y-intercept is -10/3
Step-by-step explanation:
y = mx + b
in this case:
m = 9/8
b = -10/3
and the m in the equation is the slope while the b is the y-intercept
