Answer:

24 - 3y

Step-by-step explanation:

Since the sum of the two numbers is 8, the larger number is 8 - y.

Three times the larger number: 3 (8 - y).

Simplify using Distributive property: 3 (8 - y) = 24 - 3y.

So the answer is 24 - 3y

Answer:

x  = 24  minutos

Step-by-step explanation:

Llamaremos  "y" el costo fijo mensual y "x" la cantidad de minutos consumidos al mes, según lo cual:

El enunciado del problema establece que la facturación en pesos es igual a un costo fijo  y   más el consumo en minutos del mes, entonces

En Abril    52,50  =  y  +  b*x     ⇒   52,5  =  y  +  69*b

y en Mayo   32   =  y  +  b*x      ⇒   32  =  y  + 28*b

Así obtuvimos un sistema de dos ecuaciones con dos incógnitas, que resolveremos y obtendremos los valores de b y de y

y  =  52,50  -  69*b

32 = ( 52,50  -  69*b ) + 28*b

- 20,50  =  - 41*b

b  =  0,5

y    y  =  52,5  - 69*0,5

y =  18

Entonces la ecuación de facturación es :

F(x) = 18  + 0,5*x

Para pagar como máximo 30 pesos en el mes siguiente

F(x) =  30  =  18 + 0,5*x

30 -  18  =  0,5*x

x  = 24  minutos

Answer:

B. ZJ = 85

C. KH = 68

Step-by-step explanation:

Given that ZK, ZL, ZM are perpendicular bisectors of ∆GHJ, they form a circumcenter which is equidistant from the vertices of ∆GHJ. According to the circumcenter theorem, ZH = ZG = ZJ = 85.

Also each median formed is equal. This means: KH = GH, LH = LJ, MG = MJ

Since HG = 136, KH = ½ of 136 = 68.

The two options that are true are:

B. ZJ = 85

C. KH = 68

Answer:

1) [tex]a=\dfrac{F}{m}[/tex]

2) [tex]m=\dfrac{p}{v}[/tex]

Step-by-step explanation:

1) The given equation is

[tex]F=ma[/tex]

We need to solve this for a.

In the given triangle place single variable i.e., F, on the top and variables in the product in the bottom (order of m and a does not matter) as shown in the below figure.

Using the triangle and the operations (× and ÷), we get

[tex]F=ma[/tex]

[tex]a=\dfrac{F}{m}[/tex]

[tex]m=\dfrac{F}{a}[/tex]

Therefore, the required answer is [tex]a=\dfrac{F}{m}[/tex].

2) The given equation is

[tex]p=mv[/tex]

We need to solve this for m.

In the given triangle place single variable i.e., p, on the top and variables in the product in the bottom (order of m and v does not matter) as shown in the below figure.

Using the triangle and the operations (× and ÷), we get

[tex]p=mv[/tex]

[tex]m=\dfrac{p}{v}[/tex]

[tex]v=\dfrac{p}{m}[/tex]

Therefore, the required answer is [tex]m=\dfrac{p}{v}[/tex].

Answer:

Here given

Here the length of ladder is equal to hypotenuse of ∆ so formed.

Now in a right angled ∆ ,

=> (hypotenuse)² = (pependicular)²+(base)².

=> h ² = (12m)²+(5m)²

=> h² = 144m² + 25m².

=> h² = 169m².

=> h = √169m².

=> h = 13m.

Hence the required answer is 13m.

Answer:

56

Step-by-step explanation:

First, convert the 70% so that we can use it with the 80 cups. To do this, convert the percent to a decimal by moving the decimal 2 spaces to the left:

70% → 70.00 → 0.70 → 0.7

70% percent can be seen as 0.7. Multiply this by 80:

[tex]80*0.7=56[/tex]

So, 70% of 80 is 56. Desmond sold 56 cups on the second Saturday.

Answer:

r = -7

Step-by-step explanation:

Solve for r:

8 r + 9 = -4 (3 - r) - 7

-4 (3 - r) = 4 r - 12:

8 r + 9 = 4 r - 12 - 7

Grouping like terms, 4 r - 12 - 7 = 4 r + (-7 - 12):

8 r + 9 = 4 r + (-7 - 12)

-7 - 12 = -19:

8 r + 9 = 4 r + -19

Subtract 4 r from both sides:

(8 r - 4 r) + 9 = (4 r - 4 r) - 19

8 r - 4 r = 4 r:

4 r + 9 = (4 r - 4 r) - 19

4 r - 4 r = 0:

4 r + 9 = -19

Subtract 9 from both sides:

4 r + (9 - 9) = -9 - 19

9 - 9 = 0:

4 r = -9 - 19

-9 - 19 = -28:

4 r = -28

Divide both sides of 4 r = -28 by 4:

(4 r)/4 = (-28)/4

4/4 = 1:

r = (-28)/4

The gcd of -28 and 4 is 4, so (-28)/4 = (4 (-7))/(4×1) = 4/4×-7 = -7:

f(5) = 22

Step-by-step explanation:

When we want to solve for f(x) = 5x - 3 when x is 5, all we have to do is plug in 5 as x into the equation.

f(x) = 5x - 3

f(5) = 5(5) - 3

5 * 5 = 25

25 - 3 = 22

C, (6, ∞)

Step-by-step explanation:

The x intercept is 6, and it continues downward for infinity. :) I had this question on my assignment today and it was right!

Interval of the domain for which function is negative is equals to ( 6, ∞).

" Function is defined as relation between two variable is such that for all the inputs there is exactly one output."

Standard equation of the line

y = mx + b

b = y-intercept

m = slope

According to the question,

For the given line in graph,

y- intercept = 4

x- intercept = 6

Therefore ,

For the function y = mx + b  we have,

b = 4

y = mx + 4

Substitute the value of x- intercept in the function y = mx +4 we get,

when x = 6 , y= 0

[tex]0 = m(6) + 4\\\\\implies m= \frac{-4}{6}\\ \\\implies m= \frac{-2}{3}[/tex]

Function [tex]y = \frac{-2}{3}x+ 4[/tex]

Interval of the domain is function is  negative.

[tex]y < 0 \\\\\implies \frac{-2}{3}x+ 4 < 0\\\\\implies -2x + 12 < 0\\\\\implies -2x < -12\\\\\implies 2x > 12\\\\\implies x > 6[/tex]

Interval of the domain is function is  negative is ( 6, ∞).

Hence, Option (C) is the correct answer.

Hello, first we can develop (x+a)(x+b)

[tex](x+a)(x+b)=x(x+b)+a(x+b)=x^2+bx+ax+ab=x^2+(a+b)x+ab[/tex]

We know that this should be equal to

So, we can identify the coefficients of the like terms

1 = 1 (terms in [tex]x^2)[/tex]

1 =  a + b (terms in x)

-72 = ab (constant term)

72 is 8 * 9 so, -72=9*(-8)

We are to consider the given expression:

x² + x - 72

The above expression is a quadratic expression and the objective is to determine its roots in form of (x + a) (x + b)

In form of (x + a) (x + b), the values of the expression x² + x - 72 in form of (x + a) (x + b) are 9 and -8 respectively.

From the given expression;

x² + x - 72

So; we will look for two factors of 72 in such a way that if those factors are multiplied together; they will give -72 and the addition of those two numbers will give +1.

So, the factors of 72 are:

From the above factors;

∴

Our factors are:  (-8)  and (9)

From  x² + x - 72, we have:

x² + (-8x) + (9x) - 72 = 0

(x² - 8x) + (9x -72) = 0

Opening the brackets by factorization;

x(x -8) + 9(x -8) = 0

(x + 9) or (x - 8) = 0

(x + 9) (x - 8) = 0

Recall that, we are to replace the values of a and b with the roots derived from the expression x^2 + x - 72.

Therefore, we can conclude that the values of a and b are 9 and -8 respectively.
