Answer: -1/3

Step-by-step explanation:

Slope is the difference between the y coordinate points divided by the x coordinate points

We have (-1, 2) and (-4, 3)

Slope = 3 - 2/ -4 - (-1)

Slope = -1/3

So I have this question I cannot figure out 3w+w2+1=10−w

Mandarinka [93]

Answer:

Answer: w is 1.6 or. -5.6

Step-by-step explanation:

• I guess the question asks to find the value of w

${ \rm{3w + {w}^{2} + 1 = 10 - w }}$

• arrange the equation in a quadratic equation format. i.e; ax² + bx + c = 0

${ \rm{ {w}^{2} + (3w + w) + 1 - 10 = 0 }} \\ \\ { \rm{ {w}^{2} + 4w - 9 = 0 }}$

• let's solve the equation using the quadratic formular

$\hookrightarrow \: { \tt{w = \frac{ - b \pm \sqrt{ {b}^{2} - 4ac} }{2a} }} \\$

a is 1
b is 4
c is -9

• Substitute following the mathematical operation rules:

${ \rm{w = \frac{ - 4 \pm \sqrt{ {4}^{2} - (4 \times 1 \times - 9) } }{(2 \times 1)} }} \\ \\ { \rm{w = \frac{ - 4 \pm \sqrt{52} }{2} }}$

• split the result:

${ \rm{either \: \{w = \frac{ - 4 + \sqrt{52} }{2} \} \: \: or \: \: \{w = \frac{ - 4 - \sqrt{52} }{2} \} }} \\ \\ { \rm{either \: \{w = 1.6 \} \: \: or \: \: \{w = - 5.6 \}}}$

Please explain step by step.

The slope of the line is going to be 0.25m, since the 0.25 is the cost per mile and will change as more miles are added.
the delivery fee is always going to stay the same, so that will act as the “y intercept”
t = 0.25m + 3

I am asking the same question again in the hope of finding a more detailed answer. Explain why the two figures below are not sim

Gwar [14]

The length from G to F in the larger shape is 1. Since the dilation from the first shape to the second one is 1/2, the length from N to M should be .5.
