Which number is a solution of the inequality x(7-x)>8

Mathematics
1 answer:
Lunna [17]3 years ago
7 0
X(7 - x) > 8

First solve x(7 - x)  = 8

x^2 - 7x + 8 = 0

x = 5.56, 1.44

If we plug in these values into the original equation weel see that solution is

1.44 < x < 5.56

4. Give 5 possible solutions to the equation: y = -2x + 5<br> X<br> Y
barxatty [35]

Answer:

(0, 5), (1, 3), (2, 1), (3, -1), (4, -3)

Step-by-step explanation:

To find the possible solutions, we just plug in a random value for x and then solve for y. When x - 0, y = 5. When x = 1, y = 3. We just continue doing this until we have 5 different solutions.

riangle A″B″C″ is formed using the translation (x + 0, y + 2) and the dilation by a scale factor of 2 from the origin. Which equ
Shtirlitz [24]

The relationship between segment AC and segment A double prime C double prime is AC = A''C'' /2.

<h3>What is a Scale Factor ?</h3>

The ratio by which the new image is bigger or smaller than the original image is the scale factor.

It is given that

Triangle A″B″C″ is formed using the translation (x + 0, y + 2)

and the dilation by a scale factor of 2 from the origin.

coordinate plane with triangle ABC at A (- 3,  3), B (1, - 3), and C (- 3, -3).

segment AC is equal to A''C'' over 2

Scale factor = 2

The coordinates are

A (- 3,  3), B (1, - 3), and c (- 3, -3) is translated using  (x + 2, y + 0),

new coordinates

A'(- 1,  3), B'(3, - 3), and C'(- 1, -3).

The dilation by a scale factor of from the origin

A″ (-2, 6), B″ (6, -6) and C″(-2, -6)

By the distance formula

AB = \rm \sqrt {52}

A''B'' = \rm \sqrt{ 8^2 + 12^2}\\ = 2 \rm \sqrt {52}

Therefore

AB = A''B'' /2

Similarly AC = A''C'' /2

The relationship between segment AC and segment A double prime C double prime is AC = A''C'' /2.

Find the measures of the supplementary angles if:<br><br> Their difference is equal to 35°
schepotkina [342]
Sum of <span>supplementary = 180
180 - 35 = 145

145/2 = 72.5

so
one angle = 72.5
and
its supplement = 72.5 + 35 = 107.5
