Which equation represents the line that passes through (-5,-2) and has a slope of 3

Mathematics

MrRa [10]3 years ago

You already know the slope is 3 and you have the point, so you would plug it into y = mx + b

-2 = y

3 = m

-5 = x

Plug in:

-2 = 3(-5) + b

Solve:

-2 = -15 + b

-2 (+15) = -15 + b (+15)

13 = b

Now you have b, so you can form the equation where the slope is 3x and the y-intercept is 13.

Final answer: y = 3x + 13

Billy's plant grows at least 2 inches a month.
emmainna [20.7K]
We can assume that this growth rate can be expressed as y = mx + b as long as the slope is constant, because a quadratic or exponential formula wouldn't make much sense in this situation. If it is growing at least 2 inches a month, the slope (m) will be 2. As x (month) increases by 1 month, y (plant's height) increases by 2 inches. You could make it more, but as long as you plot the points in such a way that the slope for these points are 2 or higher, you will get the answer correct. If you have any other questions or need to clarify more about what you wanted let me know and I'll help.

Automobile mechanics conduct diagnostic tests on 150 new cars of particular make and model to determine the extent to which they
galben [10]

Answer: 0.0944

Step-by-step explanation:

Given : Sample size of cars : n= 150, sample size is greater than 30 , so we use z-test.

Number of cars tested do have faulty catalytic converters =42

Then the proportion of cars   have faulty catalytic converters : \hat{p}=\dfrac{42}{150}=0.28

Critical value of z for 99% confidence level : z_{\alpha/2}=2.576

Formula for Margin of error :

E=z_{\alpha/2}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}

E=(2.576)\sqrt{\dfrac{0.28(1-0.28)}{150}}\\\\=0.0944377199216\approx0.0944\ \text{Rounded to four decimal places}

Hence, the required margin of error = 0.0944

5(2y-3)-4y=8-2y-15
dezoksy [38]
The answer is Y=1
5(2y-3)-3y=8-2y-15
10y-15-4y=8-2y-15
4y= 4y
———————————-
10y-15= 8+2y-15
15= 15
———————————
10y= 8+2y
-2y= -2y
———————————-
8y=8
—— —-
8 8
