approximate the solutions to this system.
y = 3x2 + x − 6
y = x − 4
Round your answers to the nearest hundredth.
Answer:
[tex] \displaystyle ( x_{1},y_{1}) = (0.82, - 3.18) \\ ( x_{2},y_{2}) = ( - 0.82, - 4.82)[/tex]
Step-by-step explanation:
we are given a system of quadratic and linear equation
we want to figure out x and y
in other words the coordinates where the linear function intercept quadrilateral function
to do so
you can use substitution method
since y equals to both equation so substitute:
[tex] \displaystyle {3x}^{2} + x - 6 = x - 4[/tex]
move right hand side expression to left hand side and change its sign so there's only 0 left on the left hand side:
[tex] \displaystyle {3x}^{2} + x - 6 - x + 4= 0[/tex]
simplify addition:
[tex] \displaystyle {3x}^{2} -2=0[/tex]
add 2 to both sides:
[tex] \displaystyle {3x}^{2} = 2[/tex]
divide both sides by 3
[tex] \displaystyle \frac{ {3x}^{2} }{3} = \frac{2}{3} [/tex]
[tex] \displaystyle {x}^{2} = \frac{2}{3} [/tex]
square root both sides:
[tex] \displaystyle {x} = \sqrt{\frac{2}{3} } \\ x = \frac{ \sqrt{2} }{ \sqrt{3} } [/tex]
rationalise the denominator by multiplying √3/√3:
[tex] \displaystyle x = \pm\frac{ \sqrt{6} }{3} = \pm0.82[/tex]
now let's figure out y
substitute the value of x to the linear equation:
[tex]y = \pm0.82 - 4[/tex]
when positive
[tex]y = - 3.18[/tex]
when negative
[tex]y = - 4.82[/tex]
Answer:
(x1,y1) = (0.82, - 3.18)
(x2,y2) = (-0.82, -4.82)

In the week leading up to Christmas the galaxy shopping center gives away 6700 candy canes to first 83 children visiting the center each child gets same number of candy canes how maby candy canes does each child get round your answer to nearest tenth
Answer: 80.7
Step-by-step explanation:
From the question, we are informed that in the week leading up to Christmas the galaxy shopping center gives away 6700 candy canes to first 83 children that visits the center and that each child gets same number of candy canes.
If it's shared equally among the children, each child will get:
= 6700 / 83
= 80.7 to the nearest tenth.
Linda needs 6/9 cup of strawberries and 3/4 cup mashed peach for a recipe. She wants to find whether she needs more peaches or strawberries. How can you write 6/9 and 3/4 as a pair of fractions with a common denominator?
Answer: Smashed Peach i.e. [tex]\dfrac{27}{36}[/tex]
Step-by-step explanation:
Given
Linda needs [tex]\frac{6}{9}[/tex] cup of strawberries
and [tex]\frac{3}{4}[/tex] cup of mashed peach for a recipe
For two fractions to have the same denominator, take L.C.M. of the denominator
[tex]\Rightarrow \text{L.C.M.(4,9)}=36[/tex]
[tex]\therefore \dfrac{6}{9}=\dfrac{6\times 4}{36}=\dfrac{24}{36}\\\\\Rightarrow \dfrac{3}{4}=\dfrac{3\times 7}{36}=\dfrac{27}{36}[/tex]
Therefore, she needs more mashed peach for the recipe.

The drawing plan for an art studio shows a rectangle that is 19.2 inches by 8
inches. The scale in the plan is 4 in.: 5 ft. Find the length and width of the actual studio. Then find the area of the actual studio. The length is feet, the width is feet, and the area is square feet.
Answer:
24 ft by 10 ft
240 ft
Step-by-step explanation:
19.2/4 = 4.8
4.8 · 5 = 24
8/4 = 2
2 · 5 = 10

PLEASE HELP! NO LINKS!!What is the slope of the line in the graph?
Someone help me please and no links!!!!! find the value of x
Answer:
x = 15
Step-by-step explanation:
37*2 = 74
360-74 = 286
286 = 2(9x + 8)
143 = 9x+8
135 = 9x
15 = x
Un alumno multiplica un número por 32 en lugar de multiplicarlo por 23, obteniendo un producto mayor en 54 al producto original. Halla la suma de cifras del producto original
Answer:
La suma de cifras del producto original es igual a 12.
Step-by-step explanation:
De acuerdo a la información proporcionada, si multiplicas un número "x" por 32 su resultado sería igual al producto original "y" más 54 dado que dice que se obtiene un producto mayor en 54 al producto original, lo que se puede expresar de la siguiente forma:
32x=y+54
Además, se puede inferir a partir del enunciado que si el número x se hubiera multiplicado por 23 el resultado habría sido el producto original que lo denominamos como "y", por lo que puedes decir que:
y=23x
Ahora puedes reemplazar y=23x en 32x=y+54 y despejar x:
32x=23x+54
32x-23x=54
9x=54
x=54/9
x=6
Finalmente, puedes reemplazar el valor de x en y=23x:
y=23x
y=23*6
y=138
Suma de cifras: 1+3+8 = 12

An unknown number y is 15 more than an unknown number x. The number y is also x less than 8. The equations to find x and y are shown below.
y = x + 15
y = −x + 8
Which of the following statements is a correct step to find x and y?
and could somebody please give me a step by step explanation
Answer:
x = −3.5
y = 11.5
Step-by-step explanation:
y = x + 15
y = −x + 8
[We know that y is 15 units more than x, and that −x is 8 units less than y. That can be combined into −x + 8 = x + 15 for the first variable (x), and for the second variable (y), y − 15 = −y + 8]
↓
In order to solve this, solve for the first variable in one of the equations, then substitute the result into the other equation.
↓
x = −[tex]\frac{7}{2}[/tex] = −3.5
y = [tex]\frac{23}{2}[/tex] = 11.5
what are the solutions to the expression x^2-8x=24
Answer: x= 2(2+sqrt(10)) , x=2(2-sqrt(10)
Step-by-step explanation:
x^2-8x=24 <- subtract 24 from both sides
x^2-8x-24 <- take quadratic formulat (-2+/- Sqrt(b^2 - 4ac)/2a
-(-8) +/- sqrt((-8)^2 - 4(1*-24) all over (2*1) <- simplify
(-(-8) +/- 4sqrt(10) )/2 <- sepereate
(-(-8) +/4sqrt(10) )/2 , (-(-8) - 4sqrt(10) )/2 <- simplify
2(2+sqrt(10)) , 2(2-sqrt(10) =x
