Determine the slope and the y-intercept of the line represented by the equation y=-7/9x +3 ​

Answer:

Step-by-step explanation:

1).b).  2x - 3y > 5

   For (2, 1),

   2(2) - 3(1) > 5

    1 > 5

    False.

   So the answer is NO.

c). For (6, 2),

    2(6) - 3(2) > 5

    12 - 6 > 5

    6 > 5

    True.

    Therefore, the answer is YES.

2). a). 3y + x ≤ 12

    For (3, -2),

    3(-2) + 3 ≤ 12

    -6 + 3 ≤ 12

     -3 ≤ 12

     True.

     Therefore, answer is YES.

b). For (4, 6),

    3(6) + 4 ≤ 12

     18 + 4 ≤ 12

     22 ≤ 12

     False.

     Therefore, answer is NO.

c). For (-1, -2),

    3(-2) + (-1) ≤ 12

     -6 - 1 ≤ 12

     -7 ≤ 12

     True.

     Therefore, answer is YES.

3). a). y < 3x - 15

      For (5, -3),

      -3 < 3(5) - 15

      -3 < 0

       True.

      Therefore, answer is YES.

 b). For (7, 5),

      5 < 3(7) - 5

      5 < 21 - 5

      5 < 16

      True.

      Therefore, answer is YES.

  c). For (3, -5),

       -5 < 3(3) - 5

       -5 < 9 - 5

       -5 < 4

        True.

       Therefore, answer is YES.

Answer: C.  A Ball Rolls from top to the bottom of a Hill

Step-by-step explanation: In order for this to be a displacement of 0, we need a vector quantity, so we need to specify a magnitude and direction in order to fully characterize it. Unlike distance, which can only get larger on any path taken, displacement can be positive, negative, or zero. Displacement is zero when you start and end at the same spot.

Step-by-step explanation:

step 1. slope intercept form: y = mx + b

step 2. m (slope) = (4 - 5)/(3 - 0) = -1/3.

step 3. Pick one of the points: (0, 5).

step 4. b is 5, the y intercept.

step 5. y = (-1/3)x + 5.

Answer:

Answer:

3 3/4 or 3.75

Answer:

5^12 = $244,140,625.00

Step-by-step explanation:

Step-by-step explanation:

For no 1

25 - 3x = 40

- 3x = 40 - 25

- 3x = 15

- x = 15 / 3

Therefore x = - 5

Now for no. 2

1/3 ( x - 10) = - 4

( x - 10 ) = - 12

x = - 12 + 10

Therefore x = - 2

Hope it will help :)

Answer:

1.- 5

2. - 2

Step-by-step explanation:

Answer:

48,400 yd²

Step-by-step explanation:

(220+180)/2*260=52000

1/2(180)(60)=5400

So the total area is 52000+5400=57400

Basketball court=2400

Picnic area = 4200

Playground = 40x50 + 10x40=2400

2400+4200+2400=9000

57400-9000=48400

Answer:

25520 yds

Step-by-step explanation:

Answer:

25,520

Step-by-step explanation:

The formula for yards to miles is that you have multiply the length value by 1760.

So 14.5 * 1,760 = 25,520

Answer:

333.29 cm3

Step-by-step explanation:

Answer:

$2400

$12,400

Step-by-step explanation:

Simple interest equation:

PV(1+it)

we have

10000(1+.06*4)

10000(1.24)

12400

Subtract the PV to get the interest earned

12400-10000= 2400

We just found that the total would be 12,400 and so part B is already solved

Answer:

C.

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

it is trust me

−10x+5y=10

x−5y=−28

Rewrite equations:

x−5y=−28

−10x+5y=10

Step: Solve:

x−5y=−28

x−5y+5y=−28+5y(Add 5y to both sides)

x=5y−28

Step: Substitute:

−10x+5y=10

−10(5y−28)+5y=10

−45y+280=10(Simplify both sides of the equation)

−45y+280+−280=10+−280(Add -280 to both sides)

−45y=−270

−45y

−45

=

−270

−45

(Divide both sides by -45)

y=6

Step: Substitute:

x=5y−28

x=(5)(6)−28

x=2(Simplify both sides of the equation)

Answer:

x=2 and y=6

Answer:

Answer:

7/10

Step-by-step explanation:

Answer: [tex]-\frac{7}{10}[/tex]

Step-by-step explanation:

Ordered pairs are written as (x,y)

The difference between the x coordinates is -10

The difference between the y coordinates is -7

Slope is written as [tex]\frac{rise}{run}[/tex]

So, the slope is [tex]-\frac{7}{10}[/tex]

Answer:

[tex]\displaystyle \tan A=\frac{4}{3}[/tex]

Step-by-step explanation:

Funciones Trigonométricas

La identidad principal en trigonometría es:

[tex]sen^2A+cos^2A=1[/tex]

Si sabemos que A es un ángulo agudo (que mide menos de 90°), su seno y coseno son positivos.

Dado que Sen A = 4/5, calculamos el coseno:

[tex]cos^2A=1-sen^2A[/tex]

Sustituyendo:

[tex]\displaystyle cos^2A=1-\left(\frac{4}{5}\right)^2[/tex]

[tex]\displaystyle cos^2A=1-\frac{16}{25}[/tex]

[tex]\displaystyle cos^2A=\frac{25-16}{25}[/tex]

[tex]\displaystyle cos^2A=\frac{9}{25}[/tex]

Tomando raíz cuadrada:

[tex]\displaystyle cos\ A=\sqrt{\frac{9}{25}}=\frac{3}{5}[/tex]

La tangente se define como:

[tex]\displaystyle \tan A=\frac{sen\ A}{cos\ A}[/tex]

Substituyendo:

[tex]\displaystyle \tan A=\frac{\frac{4}{5}}{\frac{3}{5}}[/tex]

[tex]\displaystyle \tan A=\frac{4}{3}[/tex]

So I didnt really understand the beginning but what I did was $325x24=$7800 payed in 24 months if we are adding the $4500 it would be

$7800+$4500=$12300

Given:

The function is

[tex]f(x)=(x+3)^2[/tex]

To find:

The domain of the given function in interval notation.

Solution:

We have,

[tex]f(x)=(x+3)^2[/tex]

Domain is the set of x-values or input values.

The given function is a quadratic function and domain of the quadratic function is all real number. The function is defined for all values of x. So, domain of the given function is the set of all real numbers.

Domain = Set of all real numbers

Domain = (-∞,∞)

Therefore, the domain of the given function is (-∞,∞).
