I'll help with a few because no-one wants to just do your homework

there is the formula way or the intuitive way

(-19, -2) (-17, -10)

now slope is (difference in y)/ (difference in x)

(y2 - y1)/(x2 - x1) the formula. where x2 just means the second x

<u>formula way:</u>

(-19, -2) (-17, -10)

(-10 - (-2))/ (-17 - (-19)) ReM: Negative on number and in the formula

(-10 + 2)/ (-17 +19) = -8/2 slope is - 8/2

<u>intuitive way</u>

(-19, -2) (-17, -10)

(difference in y)/ (difference in x)

lets looks at the ys

-2 and -10; how many steps from -2 to -10? -8 the diff in y

lets looks at the xs

-19 to -17; how many steps from -19 to -17? + 2 the diff in x

so its -8/2

Multiples of 8 that are less than 60: 8,16,24,32,40,48,56,
so the 8th run is at 8.4 am ; the 10th run is at 8.20 so u only have to wait a minute.
2-I suppose it's the third answer.
3-we can't know how many cars drive by in x minutes without knowing the value of x!

Remember, you can do anything to an equation as long as you do it to both sides

we hates fractions
times both sides by 3
(we could have added 1/3b to both sides but I'm lazy)

4b+6=12-b
add b to both sides
5b+6=12
minus 6 both sides
5b=6
divide both sides by 5
$b=\frac{6}{5}$

A student solved a quadratic equation as shown here:

djverab [1.8K]

Answer:

x = 3/2 or x = -4

Step-by-step explanation:

The identifiable error the students have is that before the left hand side of the equation is factorized, the right hand side value of 12 ought to be brought to the left hand side, leaving a net value of zero on the right hand side. Then whatever is factored on the left hand side is then equated to zero and then we can find the two values of x after setting each of the individual factors to zero

We proceed as follows;

$2x^{2} + 5x = 12\\2x^{2} + 5x - 12 = 0\\2x^{2} + 8x -3x -12 = 0\\2x(x+4) -3(x+4) = 0\\(2x-3)(x+4) = 0\\2x-3 = 0 or x+4 =0\\2x=3 or x=-4\\x = 3/2 or x= -4\\x = 1.5 or- 4$
