show work to determine if (1,4) is a solution to the system: y - 2x = 2 and y=4x - 6​

Answers

Answer:

not a solution

Step-by-step explanation:

To determine if (1, 4) is a solution to the system

Substitute x = 1, y = 4 into the equations and check validity

y - 2x = 2

y - 2x = 4 - 2(1) = 4 - 2 = 2 = right side ← True

4x - 6 = 4(1) - 6 = 4 - 6 = - 2 ≠ 4 ← False

First equation is satisfied but second is not

Thus (1, 4) is not a solution of the system

The value of the expression  [tex]\frac{1}{4} * \frac{1}{4}[/tex]  can be expressed as as a fraction as [tex]\frac{1}{16}[/tex]

What is fraction ?

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator. Every number of equal parts is represented by a fraction, which also represents a portion of a whole. A fraction, such as one-half, eight-fifths, or three-quarters, indicates how many components of a particular size there are when stated in ordinary English.

Given [tex]\frac{1}{4} * \frac{1}{4}[/tex]

Then we can multiply the numerators as well as the denominators which will gives us

Order the side from greatest to least.
Η.
28°
118°
K
J
side [Select ]

Answers

Answer:

HJ>KJ>HK

Step-by-step explanation:

Side opposite to the largest angle is the largest.

Side opposite to smallest angle is the smallest.

ang K = 118° ang J = 28°

ang K + ang J + ang H = 180° (Sum of all the angles in the triangle is 180°)

118°+28°+angH=180° (Putting the values of ang K & ang J)

146°+angH=180°

ang H=180°-146°

ang H=34°

128°>34°>28°

ang K>ang H>ang J

Here, ang K is the largest, so the side opposite to it i.e. HJ will be the largest side.

Smaller than ang K and bigger than ang J is ang H, so the side opposite to it i.e. KJ will be smaller than HJ but bigger than HK.

Ang J is the smallest angle, so the side opposite to it i.e. HK will be the smallest.

HJ>KJ>HK.

Idiomatically speaking, to write a function “in terms of” a given variable or variables means to write an algebraic expression using only that variable or variables. So for instance, given an equation x+2y−3z=0, we can solve for z in terms of x and y as z=13(x+2y).

b for which -x^2+8x+20=b will have no real roots​

Answers

Answer:

Step-by-step explanation:

-x² + 8x + 20 = b

-x² + 8x + 20 - b = 0

a = -1 ; b = 8 ; c = 20 - b

 There is no real roots.

So, b² - 4ac < 0

Plug in a, b and c values

8²- 4(-1)(20-b) < 0

When we multiply (-1) and (-4), we will get 4

64 + 4(20 - b) < 0

64 + 4*20 - 4b < 0

64 + 80 - 4b < 0

144  - 4b    < 0

Subtract 144 from both sides

-4b < -144

Divide both side by -4 and when we are dividing by (-4), < will change to >

b > -144/-4

b > 36

So, when value of b is greater than 36, the equation will have no real roots.

Answers

Answer:

Los turistas extranjeros fueron 3054 y los turistas nacionales fueron 5646.

Step-by-step explanation:

De acuerdo a la información proporcionada, debes calcular el 35,10% del total de turistas para determinar el número de turistas extranjeros y el 64,9% del total de turistas para encontrar el número de turistas nacionales:

8700*35,10%=3054
