Answer:
that would be 1
Step-by-step explanation:
if it was just 3 + 4 then it would be 7
but since it is -3 + 4
then it is just like subtracting 3 - 4 and that would be 1

2x - y = -3
-2x - 8y = 12
Answer:
x= -2 y= -1
Step-by-step explanation:
stack the 2 equations on top of each other and add them together
the 2x and -2x cancel out and you are left with -9y=9
this gives you y= -1
you plug the y value into one of the equations:
2x - (-1) = -3
2x+1 = -3
2x= -4
x= -2
8. Two pedestrians walk from opposite ends of a city block to a point on the other side of the street.
The angle formed by their paths is 125 degrees. One pedestrian walks 300 ft and the other walks
320 ft. How long is the city block to the nearest foot?
Answer: 135.606 m
Step-by-step explanation:
Try using the law of cosine because if you draw the picture of the triangle out then you see it’s a SAS triangle
so in this case:
C squared equals 320 squared plus 300 squared minus 2 times 320 times 300 times cosine 25
Factor completely > 16x^2 +48xy + 36y^2
Answer:
4 (3 y + 2 x)^2
Step-by-step explanation:
Factor the following:
36 y^2 + 48 x y + 16 x^2
Hint: | Factor out the greatest common divisor of the coefficients of 36 y^2 + 48 x y + 16 x^2.
Factor 4 out of 36 y^2 + 48 x y + 16 x^2:
4 (9 y^2 + 12 x y + 4 x^2)
Hint: | Factor by grouping.
The coefficient of x^2 is 4 and the coefficient of y^2 is 9. The product of 4 and 9 is 36. The factors of 36 which sum to 12 are 6 and 6. So 9 y^2 + 12 x y + 4 x^2 = 4 x^2 + 6 x y + 6 x y + 9 y^2 = 2 x (3 y + 2 x) + 3 y (3 y + 2 x):
4 2 x (3 y + 2 x) + 3 y (3 y + 2 x)
Hint: | Factor common terms from 2 x (3 y + 2 x) + 3 y (3 y + 2 x).
Factor 3 y + 2 x from 2 x (3 y + 2 x) + 3 y (3 y + 2 x):
4 (3 y + 2 x) (3 y + 2 x)
Hint: | Combine products of like terms.
(3 y + 2 x) (3 y + 2 x) = (3 y + 2 x)^2:
Answer: 4 (3 y + 2 x)^2

Step-by-step explanation:
i need the equation from the first question
Plz Help !!!!!!!!A line goes through the points (7, 3) and (–1, 5). Write the equation of the line in slope-intercept form. Show your work for full credit. (How did you go from those two points to having the equation in slope-intercept form? Or, how did you go form having the equation in point-slope form to slope-intercept form?) Circle your answer.
Answer:
1/-4 Rise over run. So 1 would be your rise then the 4 is negative you would fall down 4.
Step-by-step explanation:
Well you would have to do the equation y2-y1 over x2-x1. You go from having two points to having it in sloe-intercept form becuase of your equation y2-y1 over x2-x1.

Write a system of linear equations for the graph below.
We need to determine the equation of both lines first.
Line 1: y = -2x + 3Line 2: y = -1/3x - 2Now that we know the equations, we can set up a system of equations for this graph where both equations are in standard form.
Line 1:
[tex]y = -2x + 3\\\\2x + y = 3[/tex]
Line 2:
[tex]y = -\frac{1}{3}x - 2\\\\\frac{1}{3}x + y = -2[/tex]
Final answer:
[tex]2x + y = 3\\\frac{1}{3}x + y = -2[/tex]

Isabela tem dois dados de um jogo, conforme a figura a seguir: O dado 1 é numrado de 1 a 6 e o dado 2 é numerado de 1 a 8. Isabela lançou os dois dados simultaneamente. A probabilidade de que a soma obtida pelos dois números sorteados seja maior que dez é de, aproximadamente: A) 14% B) 15% C) 21% D) 27% E) 29%
Responda:
C) 21%
Explicação passo a passo:
Dado que:
Dado 1: rotulado de 1 - 6
Dado 2: rotulado de 1 - 8
Espaço amostral :
8 * 6 = 48
Probabilidade = resultado necessário / resultados possíveis totais
Resultado necessário = soma maior que 10 = 10
Resultados totais possíveis = 48
P (soma> 10) = 10/48
P (soma> 10) = 0,208333
20,8333 * 100%
= 20,833%
= 21%

Lori bought a shirt and a hat at a half off sale and she spent a total of 21$ if the shirt was originally 24 how much was the original price of the hat
Step-by-step explanation:
$21
Let the amount Lori bought the shirt and the hat be $x, if she bought them at half off sale, the initial price of both item will be 2 × $x
If she spent $21 on both items, the initial price will have been 2 x $21 = $42 where x is $21
Original price of the hat and shirt is therefore $42. Since both are on half off sale, the initial price is the hat will be $42/2 = $21
What is an equivalent expression for 3x+5x-1
Answer:
8 x - 1
Step-by-step explanation:
Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(s) for the variable(s).
(HOW DO YOU SOLVE EQIVALENT EXPRESSIONS)
Answer:
8x-1
Step-by-step explanation:
3x+5x=8x
8x-1
You add up the numbers that have the same variables, then add the extra numbers to numbers you solved.

Claire walked her dog 2 1/5 miles. Carson walked her dog 1 3/4 times as far as Claire did. How many more miles did Carson walk her dog than Claire?
The word "times" means you have to multiply.
2 1/5 times 1 3/4 is 3 17/20.
The phrase "how many more" means you have to subtract.
3 17/20 minus 2 1/5 is 1 13/20.
Carson walked her dog 1 13/20 more miles than Claire did.

A cone has a radius of 5 cm
a height of 9 cm
Volume of cone =1/3πr^2h
=1/3×3.14×5×5×9
= 3.14×25×3
=3.14×75
