Line m passes through point (5,- 8) and has a slope - 3. What is the equation for the line point slope form

Mathematics
1 answer:
skad [1K]3 years ago
7 0

Answer:

y + 8 = -3(x-5)

Step-by-step explanation:

Point Slope form is:

y - y_1 = m(x-x_1)\\\rule{150}{0.5}\\\text{ m - slope}\\(x_1,y_1) \text{  - point}\\\rule{150}{0.5}

We are given the point (5, -8) and the slope of -3.

y-y_1=m(x-x_1)\rightarrow y - (-8) - -3(x-5)\rightarrow \boxed{y+8=-3(x-5)}

The prices for different types and amounts of building bricks are given. Select the options that have the same cost per brick.
pickupchik [31]

Answer:

35 bricks for $25.90

35 bricks for $25.90

230 bricks for $170.2

Step-by-step explanation:

Cost per brick = number of bricks / price of bricks

1500/$1110 = $1.35

1300 / $845 = $1.54

230 / $170.20 = $1.35

100 / $75 = $1.33

35 / $25.90 = $1.35

Based on these calculations, the bricks that have the same cost per brick are :

35 bricks for $25.90

35 bricks for $25.90

230 bricks for $170.20

PLEASE NEED HELP NOW WILL GIVE BRAINLIEST<br> What is the value of B?
Tresset [83]
So all the angles of triangle add up to 180 degrees. So you add up the the two other sides and subtract 180 by the answer.

61 + 58 = 119

180 - 119 = 61

So, you’re answer would be 61 degrees. Hope that helped :)

What is the multiplicative rate of change for the exponential function graphed to the left?
schepotkina [342]

Answer:

The multiplicative rate of change is 3

Step-by-step explanation:

The given graph passes through the points:

(-2,\frac{2}{9}),(-1,\frac{2}{3}),(0,2),(1,6),(2,18),(3,54)

The multiplicative rate of change is the factor that multiplies each y-value to give the subsequent y-values.

We can find that factor by dividing a y-value by the previous y-value of any two consecutive y-value.

The multiplicative rate of change is \frac{6}{2}=3 or \frac{18}{6}=3 or \frac{54}{18}=3  or \frac{2}{\frac{2}{3} } =3.

Consider the graph and equation, y = 3x, that represent Alonso’s walking speed. What relationship is represented by this equatio
natita [175]

Answer:

The equation, y=3 x,

Step-by-step explanation:

y=Distance traveled

x =Total time

Also, in terms of straight line

Slope =3= uniform Velocity

Point (3,9) and (5,15) represents Distance traveled in 3 (unit of time) =9 unit, and 15 unit=Distance traveled in 5 (Unit of time).

→Alonso is moving with uniform speed=3 (unit of time), as velocity remains constant in the entire process.
