Answer:

x≥ 21 2/3

Step-by-step explanation:

81 - 1 1/5x ≤ 55

Subtract 81 from each side

81 -81- 1 1/5x ≤ 55-18

- 1 1/5x ≤ -26

Change the mixed number to an improper fraction

-(5*1+1)/5 x ≤ -26

-6/5 x ≤ -26

Multiply each side by -5/6, remembering to flip the inequality

-5/6 *-6/5x≥ -26 * -5/6

x≥130/6

Changing back to a mixed number

x≥ 21 2/3

Answer:

Answer: A

Step-by-step explanation:

[tex]81 - 1 \frac{1}{5} x \leqslant 55[/tex]

subtract 81 from both sides:

[tex](81 - 1 \frac{1}{5} x) - 81 \leqslant 55 - 81 \\ \\ - 1 \frac{1}{5} x \leqslant - 26[/tex]

express the mixed fraction into a proper fraction:

[tex] - \frac{6}{5}x \leqslant - 26[/tex]

multiply -5 on both sides:

[tex] ( - \frac{6}{5} x) \times 5 \leqslant ( - 26 \times - 5) \\ \\ 6x \leqslant 130[/tex]

divide all sides by 6:

[tex] \frac{6x}{6} \leqslant \frac{130}{6} \\ \\ x \leqslant 21 \frac{2}{3} [/tex]

As it is impossible to understand who have done what ,

the correct construction should be :

You are given point A, point B and point C.

Construct a line parallel to that line AB passing through point C.

1) Place the compass on point B, and swing an arc that crosses line AB and line BC.

 Label the points D and E.

2) Keep the compass at the same width, and place it on point C.

3) Swing an arc that crosses line BC, and label the point F outside the segment [BC] .

4) Open the compass to the width between points D and E.

 Keeping the compass at the same width, place it on point F.

5) Swing an arc that intersects the arc created from line BC at point C.

6) Mark the intersection of the two arcs as point G.

7) Draw a line through point C and point G.

You just have to discover who has done that.

Answer:

$80

Step-by-step explanation:

the original price (in percent) = 100%

the discount (25% off) = - 25%

_________________

the sale price (in percent) = 75% =>

equal to $60

so, the original price =

100/75 × $60 = $80

Now

[tex]\\ \rm\longmapsto 100-25=75\%[/tex]

[tex]\\ \rm\longmapsto \dfrac{75}{100}x=60[/tex]

[tex]\\ \rm\longmapsto x=60\times \dfrac{100}{75}[/tex]

[tex]\\ \rm\longmapsto x=80[/tex]

Answer: f(-3) = 81

Step-by-step explanation:

f(-3) = 9(-3^2)

f(-3) = 9(9)

f(-3) = 81

Answer:

f(- 3) = 81

Step-by-step explanation:

Substitute x = - 3 into f(x) , that is

f(- 3) = 9(- 3)² = 9(9) = 81

Degree of h(x) is 5 because there are 5 x intercepts

Given :

The function h(x) has a zero of x = 2 + 7i with a multiplicity of one.

Every x intercept has multiplicity 1

Explanation

x intercept x=2+7i has multiplicity one

For complex intercepts occurs in pairs

So another x intercept is x=2-7i

From the given table , when h(x) is 0 then x is the x intercepts

other x intercepts from the given table are  -5, 4,10

There are 5 x intercepts with multiplicity one

h(x) has 5 x intercepts . so , the degree of h(x) is 5

Answer:

B(5,-1)

Step-by-step explanation:

So, x1=1 and x2=x. And y1=-3 and y2=y.

So,

(1+x)/2=3, then manipulating it gives x=5.

And,

(-3+y)/2=-2, then manipulating the equation gives y=-1.

Hence B(5,-1)

Answer:

y=2x

Step-by-step explanation:

we can set x=number of week, and y=inches

as you can see, 1 week-> x=1 :y=2(1) = 2 inches

                         2 week-> x=2 :y=2(2)=4 inches

**if we substitute x to  y = 2x + 2 and y = 4x + 2, it will not works.

Answer:

[tex] \sqrt{50} + \sqrt{18} - 8 \sqrt{2} \\ \\ 5 \sqrt{2} + 3 \sqrt{2} - 8 \sqrt{2} \\ \\ 8 \sqrt{2} - 8 \sqrt{2 } \\ \\ = 0[/tex]

Given the expression:

[tex] \displaystyle \large{ \sqrt{50} + \sqrt{18} - 8 \sqrt{2} }[/tex]

Since we have 2 in the square root from 8√2. We will be converting terms in √2 form so we can. evaluate.

As we know, 50 comes from 5×10 = 5×5×2

and 18 comes from 9×2 = 3×3×2.

[tex] \displaystyle \large{ \sqrt{5 \times 5 \times 2} + \sqrt{3 \times 3 \times 2} - 8 \sqrt{2} }[/tex]

In the square root, if there are two same numbers, we can pull it out as one.

Ex. √5×5 would be 5. Refer to below:

[tex] \displaystyle \large{ \sqrt{a \times a} = \sqrt{ {a}^{2} } = |a| }[/tex]

Since there are two fives and two threes in the square root, we pull these numbers out only one.

[tex] \displaystyle \large{ 5\sqrt{2} + 3 \sqrt{2} - 8 \sqrt{2} }[/tex]

Because these terms have the same square root of 2, we can evaluate 5+3-8.

[tex] \displaystyle \large{ 8 \sqrt{2} - 8 \sqrt{2} } = 0[/tex]

Of course, like term - like term = 0

Hence, the answer is 0.

thats what it is in khan i think

Step-by-step explanation:

The presence of a midpoint will result in congruent segment.

The type of segment that the presence of a midpoint will result in is called; Congruent Segments

Now, when we are talking about congruency, we are simply referring to the concept of equality.

Thus, when we say that two angles are congruent, it simply means they are equal.

Now, when we introduce a mid point to a line segment, what this does is to divide the line into two equal parts.

Equal segments are congruent and as such we can say that congruent segments are formed.

Answer:

y = 64

Step-by-step explanation:

x = 1/8

Substituting x in the equation,

=> 2/(1/8) = y/4

=> 2 x 8 = y/4

=> 16 = y/4

=> y/4 = 16

=> y = 16 x 4

=> y = 64

The value of y will be;

⇒ y = 64

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ 2/x = y/4

Now,

Since, The expression is,

⇒ 2/x = y/4

Substitute x = 1/8, we get;

⇒ 2/(1/8) = y /4

⇒ 2 × 8 = y / 4

⇒ 16 × 4 = y

⇒ y = 64

Thus, The value of y = 64
