Find the equation of the line with slope = -7 and passing through (-7,51). write your equation in the form y=mx+b

Answers

Answer:

y = -7x + 2

Step-by-step explanation:

Since we do not have the y-intercept (or, when the x is 0) We will use the Slope Form Formula (y - y1 = m(x - x1)) to find the Slope Intercept Form Formula (y = mx + b)

Point: (-7,51)

Slope: -7

y - y1 = m(x - x1)

y - 51 = -7(x - (-7))

y - 51 = -7(x + 7)

y - 51 = -7x - 49

y = -7x - 49 + 51

y = -7x + 2

The three angles of a triangle measure 2x – 6, 3x + 5, and 2x + 20. What is the measure of the smallest angle in degrees?

Answers

Answer:

The smallest angle is 40.

Step-by-step explanation:

2x-6+3x+5+2x+20=180

7x+19=180

7x=180-19

7x=161

x=161/7

x=23

Now,

= 2x-6

= 2×23-6

= 40

= 3x+5

= 3×23+5

=74

=2x+20

=2×23+20

=66

The equation f = v + at represents the final velocity of an object, f, with an initial velocity, v, and an acceleration rate, a, over time, t. Which is an equivalent equation solved for a?

StartFraction f minus v Over t EndFraction equals a. = a
StartFraction f Over t EndFraction plus v equals a.– v = a
StartFraction f plus v Over t EndFraction equals a. = a
StartFraction f Over t EndFraction plus v equals a.+ v = a

Answers

Answer:

StartFraction f minus v Over t

EndFraction =a

Step-by-step explanation:

The equation for acceleration is a= f-v

                                                             -----

                                                                t

Rearrange f=v+at

solve for a

f= v+at   minus v

-v -v

get a by itself. multiplication is happening a between and t so divide

f-v=at

A dinner costs $4.99. Joanie plans to tip the waitress 15%. How much is the tip? (TEKS
7.4D-R)
A $0.15
B $0.75
C $5.14
D $5.74

Answers

Answer:

The tip given to waitress is $0.75. Option B is correct.

Step-by-step explanation:

Cost of Dinner = $4.99

Tip to be given to waitress = 15%

We need to find the cost of tip.

The tip would actually be given 15% of the dinner cost i,e

Tip = 15% of 4.99

Solving to find tip cost

[tex]Tip = 15\% \ of \ 4.99\\Tip=15\% \times 4.99\\Tip=\frac{15}{100} \times 4.99\\Tip=0.75[/tex]

So, the tip given to waitress is $0.75. Option B is correct.

Answers

Answer:

5 sessions

Step-by-step explanation:

For this problem, we will simply take the total cost for each gym and set them equal to each other with the missing amount of sessions represented as x.

25 + 30x = 75 + 20x

Now, we will solve for x to find how many sessions it would take for these two total costs to be equal.

25 + 30x = 75 + 20x

10x = 50

x = 5

So after 5 sessions, Ms. Pictum will have spent the same amount at both gyms.

Cheers.

Answer:

4 personal training sessions

Step-by-step explanation:

$25 + $30 = the month membership + 1 training session = $55

$75 + $20 = the month membership + 1 traing session = $95

then you would add every time she went to get a training session till you get the same number

$55 + $30 = 2 sessions and so on

$95 + $20 = 2 sessions and so on
