Answer:

y = 3x -1

Step-by-step explanation:

always remember the formula y = mx + c

m is the gradient and c is the y intercept

you already know the gradient to be 3 since the line is parallel. so, let's just imagine you are standing on the point -4, 1

for every 1 step you move on the x axis, your y value will increase by 3

thus your y intercept will be -4 + (1x3) which is - 1

by substituting the values you have just gotten, you will get your answer

Step-by-step explanation:

Answer:

46

Step-by-step explanation:

180-70=110

now we can take a guess on the other two. What two numbers added up make 110 and are 18 apart? 46 and 64 have 4 and 6. That makes 10. So now I know that the first and second angles are 46 and 64. According to the question, the first angle is smaller. So the first angle is 46.

Answer:

first angle = 46 and the second angle = 64

Step-by-step explanation:

(x,x-18,70)

x+x-18+70=180

2x+52=180

2x=180-52

2x=128

x=64

(x+x-18+70) since x is 64 replace;

x=64

x-18= 64-18= 46

Answer:

  g(x) decreasing: (-4, 0)

  f(x) ≤ g(x) on [-4, -2] U [2, 3]

Step-by-step explanation:

I agree with most of your answers.

Any point where there is a horizontal tangent will not be in that interval. That excludes x=-4 and x=0. The "decreasing" interval of g(x) is (-4, 0), with round brackets.

The domain of g is only [-4, 3], so functions f and g can only be compared on their joint domain. f(x) ≤ g(x) on the intervals [-4, -2] U [2, 3].

El consumo de agua en el año, hasta el 1 de septiembre, de la casa mencionada en el ejercicio es:

Cálculo de consumo de agua en metros cúbicos.

Para realizar el cálculo del consumo de agua en el año, debes tener en cuenta primero el consumo total de enero a noviembre brindado por el ejercicio, el cual es de:

Consumo total de enero a noviembre = 200 [tex]m^{3}[/tex]

Pero, recuerda que la casa fue arrendada el 1 de septiembre, por lo cual un arrendador requeriría verificar el agua consumida antes del arrendamiento (1 de septiembre) y el agua consumida después del arrendamiento, teniendo como base el consumo total mencionado, por tal motivo se utiliza la siguiente fórmula:

En el cálculo se resta el consumo de septiembre puesto que el arrendamiento inicia el 1 de septiembre, cuando apenas inicia el mes y por lo tanto, aún no se ha consumido agua en la casa.

Usando los valores en metros cúbicos dados por la gráfica, se procede a reemplazar la fórmula:

Y se procede a operar:

De esta manera, puedes identificar que el consumo de agua en el año, hasta el 1 de septiembre fue de 146 [tex]m^{3}[/tex].

We need more than two operations to solve a linear equation . If an equation contains fractions, multiply both sides of the equation by the least common denominator (LCD) to clear fractions.

Answer:

500g plain flour, 350g butter, 200g caster sugar, 100g smooth peanut butter, 100ml milk

Step-by-step explanation:

20÷8= 2.5

multiply each by 2.5

200n (n=2.5) = 500

140n = 350

80n = 200

40n = 100

40n = 100

Based on the information given the side length of square 3 is 10 feet.

Given:

Perimeter of square 1 =104 ft

Area of square 2=576 ft

Side length of square 3=?

Using Pythagorean theorem formula to determine the side length of square 3.

Hence,

AB=1/4×104=26ft

BC=√576=24ft

Thus,

AC=√AB²-BC²

AC=√26²-24²

AC=√676-576

AC=√100

AC=10 feet

Inconclusion the side length of square 3 is 10 feet.

Answer:

(A) Two acute angles add to an obtuse angle

It's sometimes because for example if you take two acute angles

one is 30 and other is 20

they add to 50 and not greater than 90 so it can be sometimes greater but not always

(B) Two adjacent angles make a line

Its also sometimes because a line means it should be 180 degrees so two adjacent angles can out always be equal to 180 that is a line

(C)Two obtuse angles are supplementary

It's Never true because obtuse angles start from 90 so if you take 91 also and other 91 too so if we add them up  that will be 182 not 180

as we know 180 = supplementary angle that's why

Answer:

It is 270, 810 and 2430

Step-by-step explanation:

10 x 3 = 30

30 x 3 = 90

90 x 3 = 270

270 x 3 = 810

810 x 3 = 2430

Answer:

Step-by-step explanation:

1) x² + 6x + 11 = 0

a = coefficient of x² = 1

b = coefficient of x = 6

c = Constant = 11

Roots = (-b ± √b² - 4ac)/2a

[tex]D = \sqrt{b^{2}-4ac}\\\\=\sqrt{6^{2}-4*1*11}\\\\=\sqrt{36-44}\\\\=\sqrt{-8}\\\\=\sqrt{8i^{2}}\\\\ = 2i\sqrt{2}[/tex]

Roots = [tex]\dfrac{-6 \± 2i\sqrt{2}}{2}\\[/tex]

          [tex]= \dfrac{2(-3 \± i\sqrt{2})}{2}\\\\=-3 \± i\sqrt{2}[/tex]

2) 2x² - 16x = 50

Divide the whole equation by 2

x² - 8x = 25

Divide the coefficient of x  (i. e 8 ) by 2 = 8/2 = 4, Now add 4 to both sides of the equation

x² - 8x + 4 = 25 + 4

x² - 2*4*x + 2² = 29

(x - 2)² = 29

Take square root both side

[tex]x - 2 = \± \sqrt{29}\\\\x = 2 \± \sqrt{29}[/tex]

Angles DUT and VUD sum to VUT. We can create an equation to model this.

DUT + VUD = VUT

Now, let's plug our values into the equation.

24x + 5 + 46 = 35x - 4

Simplify the left side.

24x + 51 = 35x - 4

Subtract 24x from both sides and add 4 to both sides.

55 = 11x

Divide both sides by 11.

5 = x

Answer:

2,4 8,8

Step-by-step explanation:

im not sure

hi <3

lets create variables for our unknowns

width = n

length = 4.5n

now lets input the information we know:

4.5n x n = 36

simplify:

4.5n^2 = 36

divide both sides by 4.5:

n^2 = 8

n = square root of 8

therefore, the width is 2.83 (to 2dp) and length is 12.73 (to 2dp)

hope this helps :)
