-5(x+6)=15 what is the answer?? will give brainliest

Answer:

The x-coordinate of A is:

a = 6.1

Step-by-step explanation:

For point A:

x-coordinate = a

x-coordinate + y-coordinate = 14

y-coordinate = 14 - x-coordinate

y-coordinate = 14 - a

So point A can be written as (a, 14-a)

Let (a,14) be (x₁,y₁)

Point P can be written as (3a, a²+13a-11)

Let P be (x₂,y₂)

Slope of a line passing through 2 point is given as:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

where m=7

Substitute all values

[tex]7=\frac{(a^2+13a-11)-(14-a)}{3a-a}\\7=\frac{a^2+13a-a-11-14}{3a-a}\\7=\frac{a^2+12a-25}{2a}\\14a=a^2+12a-25\\a^2-2a-25=0\\a=6.1,a=-4.1[/tex]

As A has only positive coordinates

a = 6.1

Answer:

it's not 2/5 I got it wrong the correct answer is 1/10,000

Step-by-step explanation:

Answer:

The value of x is -2.

Step-by-step explanation:

First, you have to eliminate the brackets by expanding :

[tex]2(x - 4) = 4(2x + 1)[/tex]

[tex]2x - 8 = 8x + 4[/tex]

Next, you have to move all the like-terms to one side :

[tex]2x - 8 - 8x = 4[/tex]

[tex] - 6x = 4 + 8[/tex]

[tex] - 6x = 12[/tex]

[tex]x = 12 \div ( - 6)[/tex]

[tex]x = - 2[/tex]

Answer:

[tex]x = - 2[/tex]

Step-by-step explanation:

[tex]2(x - 4) = 4(2x + 1) \\ 2x - 8 = 8x + 4 \\ 2x - 8x = 8 + 4 \\ - 6x = 12 \\ \frac{ - 6x}{ - 6} = \frac{12}{ - 6} \\ x = - 2[/tex]

Answer:

c = 2500

Step-by-step explanation:

[tex]x^2+100x + c\\x^2+2\times 50\times x + (50)^2\\=x^2+2\times 50\times x + 2500\\=x^2+100 x + 2500\\equating \: it \: with\: \\x^2+100x + c\\we\; find:\\c = 2500[/tex]

Answer:

c = 2500

Step-by-step explanation:

x² + 100x + c  where c = ?

100 x :    100x / 2x = 50

(50)² = 2500

Answer:

7 Gallons every minute

Step-by-step explanation:

We know that a total of 42 gallons of water was pumped for 6 minutes at a constant rate. Constant rate means that it will always pump the exact same amount of water each time. Eince its at a constant rate we just need to find out how much water was poured over the course of a minute, which can be done by dividing 6 (minutes) by 42 (gallons of water) = 7 gallons of water.

Answer:

Step-by-step explanation:

length (l) = 3 ft

Width (w) = 3 ft

Height (w) = 6 ft

Surface area = 2*( lw  + wh + hl)

                    = 2* (3*3 + 3*6 + 6*3)

                    = 2*(9 + 18 + 18)

                   = 2 *  45

                   = 90 square ft

Answer:

a) The graph is a horizontal shift of the parent function 2 units right.

Step-by-step explanation:

Explanation:-

Type of transformation                       Change to co-ordinate point

Vertical translation up 'd' units                   (x,y) →(x ,y+d)

Vertical translation down 'd' units               (x,y) →(x ,y- d)

Horizontal translation left 'c' units               (x,y) →(x-c ,y)

Horizontal translation right 'c' units            (x,y) →(x+c ,y)

Reflection over X-axis                                   (x,y) →(x ,-y)

Reflection over y-axis                                    (x,y) →(-x ,y)

Given graph  f(x)  = √x

The graph is a Horizontal shift of the parent function  '2' units  right

Therefore the transformation of the graph [tex]y = \sqrt{x+2}[/tex]

Answer:

x=-4

Step-by-step explanation:

Ohhh you wrote 4 on the other post, not 4x.

Okay.

6(x+3)-4x=10

6x+18-4x=10

2x=-8

x=-4

Answer:

The value of [tex]x[/tex]:

[tex]x = -4[/tex]

Step-by-step explanation:

Solve for [tex]x[/tex]:

[tex]6(x+3) - 4x = 10[/tex]

Use Distributive Property:

[tex]6(x+3) - 4x = 10[/tex]

[tex]6x + 18 - 4x = 10[/tex]

Combine [tex]6x[/tex] and [tex]-4x[/tex] together:

[tex]6x + 18 - 4x = 10[/tex]

[tex]2x + 18 = 10[/tex]

Subtract both sides by [tex]18[/tex]:

[tex]2x + 18 - 18 = 10 -18[/tex]

[tex]2x = -8[/tex]

Divide both sides by [tex]2[/tex]:

[tex]\frac{2x}{2} = \frac{-8}{2}[/tex]

[tex]x = -4[/tex]

So, therefore, the final answer is [tex]x = -4[/tex] .

The answer is 78

Answer:

x =3.

Step-by-step explanation:

This is an isosceles triangle  so the 2 sides opposite the equal angles are congruent.

So  3x + 2 = 11

3x = 9

x = 3.

Answer:

49 and 2/3

Step-by-step explanation:

3x+2+18+11=180

3x+31=180

3x=149

x=49 and 2/3

Answer:

About 188.71 feet

Step-by-step explanation:

The cosine of an angle is equivalent to the adjacent side divided by the length of the hypotenuse. Therefore:

[tex]\cos 58=\dfrac{100}{x} \\\\x=\dfrac{100}{\cos 58}\approx 188.71[/tex]

Hope this helps!

Answer:

x = 188.71

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos theta = adjacent/ hypotenuse

cos 58 = 100/x

Multiply by x

x cos 58  = 100

Divide by cos 58

x = 100/cos 58

x =188.7079915

To the nearest hundredth

x = 188.71

You can use our formula for the surface area of a rectangular prism for a cube as well. A cube is a rectangular prism where all its sides are the same. The formula to find the surface area of a rectangular prism is A = 2wl + 2lh + 2hw, where w is the width, the l is the length, and the h is the height.
