Write an equation in point-slope form and slope-intercept form

liq [111]

Answer:

point-slope form: y - 1 = -4/5(x - 8)

slope-intercept form: y = -4/5x + 7.4

Step-by-step explanation:

Find slope using the points (8, 1) and (-2, 9):

m = (y₂ - y₁) / (x₂ - x₁)

= (9 - 1) / (-2 - 8)

= 8 / -10

m = -4/5

Find y-intercept using slope m from above and anyone of the given points, let's use (8, 1):

y = mx + b

1 = -4/5(8) + b

1 = -6.4 + b

b = 7.4

Use slope m and y-intercept b above to form equation of line in slope-intercept form:

y = mx + b

y = -4/5x + 7.4

For point slope form use slope m from above and a point, again let's use (8, 1):

y - y₁ = m(x - x₁)

y - 1 = -4/5(x - 8)

In the equation -3(y-2)2/3+29=-19, the values of y are

Elodia [21]

See attached explanation.: Answer: y=26 or

Step-by-step.(−3(y−2))(2)3+29=−19
Step 1: Simplify both sides of the equation.(−3(y−2))(2)3+29=−19Simplify: −2y+4+29=−19 (Distribute)(−2y)+(4+29)=−19 (Combine Like Terms)−2y+33=−19−2y+33=−19

Step 2: Subtract 33 from both sides.−2y+33−33=−19−33−2y=−52

Step 3: Divide both sides by -2.−2y−2=−52−2y=26Answer: y=26

Can someone please help I tried to attempt it but it wasn’t working for me

kakasveta [241]

b. It depends on the value you assume for the power line voltage. If you assume it is 120 volts, then the ratio to battery voltage is

... (120 volts)/(1.2 volts) = 100

Power line voltage is 100 times as large as battery voltage.

_____

Please be aware of some difficulties in this question.

1. Power line voltage, even if it is "120 volts" varies over time from -170 V to +170 V, so is not really comparable to a battery's voltage, which is steady at 1.2 V.

2. The terminology "times larger" is ambiguous. When we answer the question, "how much larger is a than b," we give the response in terms of the difference a-b. Thus, if a is 2 times larger than b, we might be talking about the difference being twice the value of b. It is preferable to say "times as large as."

The energy that generates wind comes from what source A. Soar radiation B. Magnetic attraction C. Moon's gravity D. Coriolis eff

lbvjy [14]

Answer:

A. Soar radiation

Step-by-step explanation:

Blowing wind rotates the wind turbine and generates the energy called wind energy. More the speed of wind, more the energy can be generated.

That's how, wind energy depends on the speed of the wind and the speed of the wind is due to the pressure difference in various regions.

The zone having more solar radiation has low pressure and the zone having less solar radiation have high pressure of air and winds flows from high to low-pressure zone.

Therefore, the energy that generates wind comes from what source soar radiation.

Hence, option (A) is correct.
