Answer:

The equation is y-(-8) = 4(x-2).

Step-by-step explanation:

The point-slope form of a line is represented by the formula y-y_1 = m (x-x_1). In order to write an equation of a line in point-slope form, we would need to substitute real values for the m, x_1, and y_1 in the formula.

Since m represents the slope of the line, substitute 4 in its place. Since x_1 and y_1 represent the x and y values of one point the line intersects, substitute the x and y values of (2,-8) in the formula as well. Substitute 2 for x_1 and -8 for y_1. This results in the following equation and answer:

y-(-8) = 4(x-2)

(Usually, we would simplify the double negatives on the left side to a positive, but because you have to type the values in to answer the problem and cannot change the written negative sign already visible in the equation, that would be the answer. I believe you can just type in -8 for the first box.)

What is the value of the 1 in 178
Igoryamba
The value of 1 in 178 is 100 since it is in the hundreds place.  The value of 7 in 178 is 70 and the value of 8 in 178 is 8.  The hundreds place carries numbers from 1 to 9.  Once you get to 10, you add a digit to the number such that you now have four total numbers and the first digit is in the thousands place.

The temperature in Miami, Florida is 22 degrees warmer than three times the temperature in Bangor, Maine. The temperature in Mia
Nastasia [14]

Answer:

y=\frac{x-22}{3} ; y=20

Step-by-step explanation:

Let Temperature of Maimi T_{m}  and that of Bangor be T_{b}

Given in the condition is T_{m} is 22 more than 3 times  T_{b}

i.e. T_{m} = 22+ 3 * T_{b}

Hence

T_{m} - 22 = 3 * T_{b}

T_{b} = \frac{T_{m}-22}{3}

Here also we are given that T_{m}=82

T_{b} = \frac{82-22}{3}

T_{b} = \frac{60}{3}

T_{b} = 20

An isosceles triangle has base angles that each measure 39 °. Which equation can be used to fi nd t, the measure of the third an
Montano1993 [528]

Answer: 102°

Step-by-step explanation:

First and foremost, we should note that an isosceles triangle has two sides that are equal and that the sum of angles in a triangle equals to 180°.

Since we are told that the isosceles triangle has base angles that each measure 39°, the third angle will be:

t + 39° + 39° = 180°

t + 78° = 180°

t = 180° - 78°

t = 102°

The third angle is 102°.
