Which of the following statements must be true about the polynomial function f(x)

By solving linear inequation, it can be calculated that

The system of linear inequation represented by the graph is

What is linear inequation?

Inequation shows the comparison between two algebraic expressions by connecting the two algebraic expressions by >,<, ≥, ≤

A one degree inequation is known as linear inequation.

Here,

One line passes through (0, 8) and (-1, 7)

Slope of the line = [tex]\frac{7-8}{-1-0}[/tex] = 1

Equation of line

y - 8 = 1(x - 0)

y - 8 = x

x - y = -8

Other line passes through (-4, 4) and (-3, 1)

Slope of the line = [tex]\frac{1-4}{-3-(-4)}[/tex] = -3

Equation of line

y - 4 = -3(x - (-4))

y - 4  = -3x - 12

3x + y = 4 - 12

3x + y = -8

Now the lines are solid lines

So equality is maintained

(0, 0) is inside the shaded region

So the system of linear inequation represented by the graph is

x - y ≥ -8

3x + y ≥ -8

Because when two linear equations graph this very same line, a system of two linear simultaneous equations variables cannot be solved.

A linear equation seems to be an algebraic equation of something like the form y=mx+b, where m is the slope as well as b is the y-intercept, and only a constant and an initial-order (linear) component are included. The variables in the preceding equation are y and x, and it is occasionally referred to as a "linear equation of two variables."

2x+6y=-28       (i)

Answer:

l =  10 feet

m = 30 feet

n = 25 feet

Total Perimeter = 65 feet

Step-by-step explanation:

The perimeter of a trianlge is the sum of its three sides, and in this case is equal to 65 feet.

65 feet = l + m + n

l + m + n = 65

We also know that:

 l = (1/3)m, and

n = l+m-15

Substitute these definitions of l and n into the original equation:

l + m + n = 65

[(1/3)m] + m + [l+m-15] = 65

[(1/3)m] + m + [[(1/3)m]+m-15] = 65

Simplify:

(1/3)m + m + (1/3)m + m - 15 = 65

2m + (2/3)m = 80

(6/3)m + (2/3)m = 80

(8/3)m = 80

m = 80*(3/8)

m = (10)*(3)

m = 30 feet

Since l = (1/3)m, l = 10 feet

Since n = l+m-15, n = 10 + 30 - 15, or 25 feet

The three sides are

      l:    10 feet

     m:  30 feet

     n:   25 feet

Total = 65 feet

225 km travels in =25 ltr

1 km travel = 225 25

540 km will require = 22525 ×540=60 L

Was this answer helpful?

Answer:

1) 540 km

2) 6 liters of petrol

Step-by-step explanation:

To answer the two questions, it is easiest to fist find the relationship between kilometers (km) and liters of petrol. Since 7 liters (L) results in 315 km, we can find the km/liter petrol conversion factor (converts liters of petrol to km):

(315 km)/(7 liters) = 45 km/L

1) 12 liters times the conversion factor will tell us how many km the motorcycle will travel"

(12 liters)*(45 km/liter) = 540 km [Note that the liters unit cancles, leaving only km]

2) To find the liters of petrol to travel 270 km, we can use the same conversion factor, but now we need to divide to get the units we want, which is km:

(270 km)/(45 km/l) = 6 liters [Note that km cancels and l moves to the top, leaving liters as the only unit.

The distance between the line containing the points (0,-3) and (7,4) and the point P(4,3) is d =√2 units.

The distance between the line ax +by +c =0 and the point (x₁, y₁) is given by:

[tex]d=\frac{|ax_{1}+by_{1}+c|}{\sqrt{a^2+b^2}}[/tex]

Given that, the line passes through the points (0,-3) and (7,4).

The equation of the line is given by:

[tex]y -(-3)=\frac{4-(-3)}{7-0}(x-0)\\\\y+3=x\\\\x-y-3=0[/tex]

Now, the distance between the line x - y - 3 = 0 and point (4,3) is:
[tex]d=\frac{|1\times4+(-1)\times3+(-3)|}{\sqrt{1^2 +(-1)^2}}\\\\d=\frac{2}{\sqrt{2}}\\\\d=\sqrt{2}[/tex]

Using the formula of compound interest, the amount accumulated over 4 years is $15,849.46

Compound interest is the interest calculated on the principal and the interest accumulated over the previous period. It is different from simple interest, where interest is not added to the principal while calculating the interest during the next period. In Mathematics, compound interest is usually denoted by C.I.

The formula is often given as;

C.I = P(1 + r/n)^nt

Substituting the values into the formula

C.I = 200(1 + 0.0105/12)^12*4

However, over the period of 4 years, the Principal becomes

Principal = 200 * 4 * 12 = 9600

Rate = 1.05 * 12 = 12.6

C.I = 9600(1 + 12.6/12)^12 * 4

C.I = $15,849.46

If LMNO is a parallelogram then NM=7=OL and the value of X is 7 unit

What is a Parallelogram?

A quadrilateral having two sets of parallel sides is referred to as a parallelogram. In a parallelogram, the opposing sides are of equal length, and the opposing angles are of equal size. Additionally, the interior angles that are additional to the transversal on the same side. 360 degrees is the sum of all interior angles.

A parallelepiped is a three-dimensional shape with parallelogram-shaped faces. The base (one of the parallel sides) and height (the distance from top to bottom) of the parallelogram determine its area. A parallelogram's perimeter is determined by the lengths of its four sides.

As it is a parallelogram so, the opposite sides of the parallelogram are equal so NM=OL and ON=LM ,

according to the question ;-

NM = x+5

OL=2x+3

and NM=OL

x+5=2x+3

Step-by-step explanation:

Answer:

n = p+3q

Step-by-step explanation:

2^p x 8^q = 2^n

Exponent rules

Rewriting 8 as 2^3

2^p x 2^3^q = 2^n

Using the rule a^b^c = a^(b*c)

2^p x 2^3q = 2^n

Using the rule a^b * a^c = a^(b+c)

2 ^(p+3q) = 2^n

Since the bases are the same, the exponents are the same

p+3q = n

Answer:

[tex] \sf \: p + 3q = n[/tex]

Step-by-step explanation:

[tex]2^p*8^q=2^n[/tex]

First, write 8^q as a power of 2.

[tex]2^p*8^q=2^n\\2^p*2^3^q=2^n[/tex]

As all the bases are same, exponents are also equal.

Now add the powers.

∴ p + 3q = n

Linear equations: Any equation that can be expressed as ax + by + c = 0, where a, b, and c are all real numbers and a and b are not equal to zero.

In light of the posed query.

Khalid keeps bees and sells honey from them.

Additionally, n stands for the neighbor's honey price in dollars and r stands for the ordinary honey price in dollars.

We can determine the discount from the provided information.

7 - 4.50 = 2.50

8 - 5.50 = 2.50

10 - 7.50 = 2.50

12 - 9.50 = 2.50

Khalid gives his neighbor $2.50.

The equation for the link between the regular price r and the neighbor's price n will therefore be: r - n = 250
