Answer:
Step-by-step explanation:
-2x - 20y = -34
2x + 6y = 6
-14y = - 28
y = 2
x + 20 = 17
x = -3
(-3,2)
The answer is A
solve for x −7.8(x+6.5)=−25.74
Answer:
the correct answer is x= -312/85

Gina takes three hours of dance classes for x weeks. Which expression shows the number of hours Gina dances?
x - 3
x + 3
3x
x ÷ 3
Answer:
3x
Step-by-step explanation:
x = number of weeks.
When you plug in the number of weeks for x you'll get the amount of hours she had for dance classes.
Example: She has been doing classes for 3 weeks, how many hours did she do?
3x
3(3)
= 9(She had 9 hours of dance class combined for the past three weeks).

como seria una ecuacion de (2,3) si la pendiente es -2
Answer:
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
Espero esto haya ayudado en algo, sino puedes intentar buscando en el sitio que recomende.

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.
Solve for r when
- 5 = – 4
-
20
r=
What is r?
Answer:
r is 19
Step-by-step explanation:
-4 - 20 = -24
-24 - r = -5
r = 19
Answer:
r=1/20
Step-by-step explanation:
-5=-4-20r (+4 both sides)
-1=-20r (times -1 both sides)
1=20r (divide by 20)
1/20=r

write the equation of the line
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.
The difference between two numbers is 85. The smaller number is 237, what is the larger number?
Answer:
322 is the bigger number
Step-by-step explanation:
Answer: 322
Step-by-step explanation:
d = difference
l = larger number
237 + d = l
237 + (85) = l
l = 322

A line passes through points with coordinates
(3,7) and (-2,-3). What is the equation of the
line?
1) y = 2x + 1
2) y = 2x + 4
3) y = -2x +1
4) y = = -2x + 13
Answer:
y = 2x + 1
Step-by-step explanation:
[tex]m = \frac{-3 - 7}{-2 - 3}\\ = \frac{-10}{-5}= 2\\y = mx + b \\y = 2x + b\\7 = 2(3) + b\ -> 7 = 6 + b \\b = 1 \\y = 2x + 1[/tex]
20yz/28xyz simplify.
Answer:
5/7X
Step-by-step explanation:
cancel Y and Z from both sides
get the HCF (highest common factor) between 20 and 28 which is 4
then divide both sides with 4
the final answer will be:
5/7X

Answer:
GCHE
Step-by-step explanation:
Answer and Explanation:
Problem 1:
4x - 12 = 16
4x = 28
x = 28 / 4
x = 7, G
Problem 2:
5x + 10 = - 25
5x = - 35
x = - 35 / 5
x = -7, C
Problem 3:
x / 2 + 11 = 12
x / 2 = 12 - 11 = 1
x = 2 * 1
x = 2, H
Problem 4:
7.5 * x + 10 = -5
x = -2, E
(Not sure about this one)
Code: GCHE
