write the equation of the line

Answers

Answer:

y = (3/-2)x + 4.

Step-by-step explanation:

slope intercept form is y = mx + b

1. Lets first look for the y intercept (b). On the graph the line intercepts the y axis at 4. 4 is our b.

2. To find the slope (m) remember rise over run. Counting from lower dot, it goes up 3 and left 2. 3/-2. The two is negative because it is decreasing (towards the left of the graph).

3. Now plug the numbers into slope intercept form. y = (3/-2)x + 4.

Answers

Answer: 150 pounds

Step-by-step explanation:

Let the the astronaut weight on Earth be represented by x.

Based on the information given in the question, thus can be formed into an equation as:

16.5% of x = 24.75

16.5% × x = 24.75

16.5/100 × x = 24.75

0.165x = 24.75

x = 24.75/0.165

x = 150 pounds

The astronaut weigh 150 pounds on Earth.

Hola, antes de dar la respuesta quisiera recomendarte una app llamada m a t h w a y (sin espacios) esto te va a ayudar con preguntas sobre matematica y super rapido.

Step-by-step explanation:

(2,3) pendiente de -2

                                           1. Usa la fórmula de la ecuación de la recta para

                                              hallar b

y = mx + b

                                          2.  Substituye el valor de m, x y "y" en la ecuacion

3 = (-2) · (2) +b                      

                                           3. Calcula para hallar el valor de b

b = 7

                                          4. Ahora con el valor de b, calcule de nuevo

y = mx + b

3 = -2x +7

Answers

Answer: m=−3

Step-by-step explanation: −40−2(3m+1/2)=7m−2

−40+(−2)(3m)+(−2)(1/2)=7m+−2

−40+−6m+−1=7m+−2

(−6m)+(−40+−1)=7m−2

−6m+−41=7m−2

−6m−41−7m=7m−2−7m

−13m−41+41=−2+41

−13m/−13=39/−13

m=−3

What mistake I guess Keith did make is he subtracted 2 from -39 which equaled to -37 which caused him divide -37 by 13 when it should have been 39 divided by 13 because he should have left 39 alone and not have subtracted 2 from it also it should not have been negative basically what I'm trying to say is that he did his division and subtraction wrong.

 

m = -3, hope it was helpful! :)

Ali can bake 105 cookies in 3 hours. At that rate, how many cookies can she bake in 5 hours?

Answers

so first you find out how many she can bake in 1 hour so you divide 105 and 3 which is 35

so since she bakes 35 cookies and hour you multiply 35 by how many hours she cooks

so 35 x 3 =105                    35 x 5=175

Ali cooks 175 cookies in 5 hours

175 cookies is the correct answer105 ÷ 3 = 3535 x 5 = 175Please let me know if I am wrong.
