Answer:

a). x = 10.20 in

b). x = 2.24

Step-by-step explanation:

a). By applying Pythagoras theorem in the given right angle,

    (Hypotenuse)² = (Leg 1)² + (Leg 2)²

    (15)² = x² + (11)²

     225 = x² + 121

     x² = 225 - 121

     x² = 104

     x = √104

     x = 10.198 ≈ 10.20 in

b). By applying Pythagoras theorem,

    (3x)² = (2x)² + (5)²

     9x² = 4x² + 25

     9x² - 4x² = 25

     5x² = 25

      x² = 5

    x = √5 = 2.24

Answer:

The expression to find the perimeter is [tex]12x^2-6[/tex].

Step-by-step explanation:

Given: The side lengths of the triangle are [tex](4x^2-3)[/tex] inches, [tex](4x^2-2)[/tex] inches, and [tex](4x^2-1)[/tex] inches.

To find: The expression that can be used to find the perimeter of the triangle.

Solution:

We have,

The side lengths of the triangle are [tex](4x^2-3)[/tex] inches, [tex](4x^2-2)[/tex] inches, and [tex](4x^2-1)[/tex] inches.

We know that,

The perimeter of a triangle is sum of all the sides.

So, Perimeter [tex]=(4x^2-3)+(4x^2-2)+(4x^2-1)[/tex]

[tex]\implies \text{Perimeter}=12x^2-6[/tex]

Hence, the expression to find the perimeter is [tex]12x^2-6[/tex].

Answer:

Inequality Form:  x ≤ 1

Interval Notation:  (−∞, 1]

Step-by-step explanation:

24 ≤ 8 (7 − 4x)

Rewrite so x is on the left side of the inequality.

  8 (7 − 4x) ≥ 24

Divide each term by 8 and simplify.

Divide each term in 8 (7 − 4x) ≥ 24 by 8.

  8 (7 − 4x)/8   ≥      24/8

Cancel the common factor of 8.

  7 − 4x  ≥ 24/ 8

Divide 24 by 8.

  7 − 4x  ≥ 3

Move all terms not containing x to the right side of the inequality.

  −4x  ≥ −4

Divide each term by −4 and simplify.

  x ≤ 1

The result can be shown in multiple forms.

Inequality Form: x ≤ 1

Interval Notation: (−∞, 1]

yea the  sorry

Answer:

y = 2. It is a horizontal line.

Step-by-step explanation:

The asymptote is the line that the function comes close to touching, but never will. Because the range is y > 2, you know that any value greater than 2 can and will be a y-coordinate, but the function will never have 2 as a y-coordinate. It will never touch the line y = 2, and therefore, y = 2 is the asymptote. Hope this helps!

Answer: The new container folds 100 fluid ounces.

Step-by-step explanation:

Given: A company claims that their new bottle holds 25% more laundry soap.

If original container hold 80 fluid ounces.

Then, Quantity of soap in the new container = 80 fluid ounces + 25% of 80 fluid ounces

= [80+0.25 x 800]  fluid ounces               [ 25% = 0.25]

= 80+ 20= 100 fluid ounces  

Hence, the new container folds 100 fluid ounces.

Answer:

66.25

Step-by-step explanation:

Answer:

The value of x = 13.7.

Step-by-step explanation:

Given

Hypotenuse = c = 16.5

a = 9.2

To determine

x = b ?

For a right-angled triangle with sides a, and b the hypotenuse is defined as

[tex]c=\sqrt{a^2+b^2}[/tex]

In our case, we have to get x

[tex]b=\sqrt{c^2-a^2}[/tex]

so substituting b = x, c = 16.5, a = 9.2

[tex]x=\sqrt{16.5^2-9.2^2}[/tex]

[tex]x=13.7[/tex]

Therefore, the value of x = 13.7.

Answer:

85

Step-by-step explanation:

2(-4)^2=32

-10(-4)=40

32+40+13=85

We can say that the y intercept is at the location (0,-1)

This is where the graph crosses the vertical y axis. This is 1 unit below the origin.

This is assuming each tickmark on the grid represents 1 unit.

Answer:

The y- intercept is (0,-1)

Step-by-step explanation:

A y- intercept is when a point intercepts (crosses) the y- axis. Since the dot does not cross the x- axis, that point will be 0. It is below the y- axis, meaning it will be -1.

Answer:

n < 5

Step-by-step explanation:

6(3 + n) < 48

when you see parentheses you multiply so it would be 6 x 3 which is 18 then 6 x n which would be 6n so it simplified some would be 18 + 6n < 48 then to get the numbers on the same side and 6n on the other you would -18 from both sides so the one on the left side of the equation cancels out 6n < 48 - 18 then do the math which would be 30 then you divide by 6 to get the n by itself 30/6 is 5 so n is smaller than 5 or n < 5

Answer:

[tex]\frac{9}{10}[/tex] ÷ [tex]\frac{3}{5}[/tex]

=3/5

ur daddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd

Answer:

the desired solution is (2, 2)

Step-by-step explanation:

Solve this using elimination by add'n/subtr'n.

Multiply the first equation by 2, obtaining the equivalent set of equations:

2x - 2y = 0

3x + 3y = 10

Combining like terms, we get 5x = 10, and thus x must be 2.

Subbing 2 for x in the first equation yields 2 - y = 0, or y = 2.

Then the desired solution is (2, 2).

Answer:

To make 6 cups, you will need 2 cups of lemon and 4 cups of water....6 total

TWO of the six are lemon    2/6 x 100 = 33.33% Lemon    the rest is water  100-33.33= 66.67% water

OR

FOUR out of the SIX are water    4/6 x 100 = 66.67% Water

Answer:

9x - 2y = 0

Step-by-step explanation:

Given

x - 3y = 6 → (1)

- 8x - y = 6 → (2)

Subtracting (2) from (1) term by term gives

x - (- 8y) - 3y - (- y) = 6 - 6 , that is

x + 8y - 3y + y = 0

9x - 2y = 0

Answer:

use the slope equation (y2-y1) / (x2 -x1). plug in values and solve

(-1 -7) / (9 -(-3)) (subtracting a negative is the same as adding a positive)

-8 / 12 (simplify)

m = -2/3

then, plug in one of the points and the slope into the slope-point equation.

(y - y1) = m (x - x1) (the point-slope form)

y - 7 = -2/3( x - (-3)) (plug in the slope and point 1 values, then solve)

y - 7 = -2/3x - 2 (add 7 to both sides)

y = 2/3x +5 (the answer)
