Solve equation for 5(x - 3) + 2 = 5(2x - 8) - 3​

Answer:

y = -15/8x - 35/8

Step-by-step explanation:

Find the slope = [tex]\frac{change in y}{change in x}[/tex]

                         = [tex]\frac{80 - 5}{-45 - (-5}[/tex])

                         =  [tex]\frac{75}{-40}[/tex]

                         =   [tex]\frac{-15}{8}[/tex]

Find the y-intercept    Use one point (-5, 5) and the slope  [tex]\frac{-15}{8}[/tex]

 y = mx + b

 5 =  -15/8 (-5) + b

  5 = 75/8 + b

  5 - 75/8 = b

   -35/8 = b

Write the equation  

         y = -15/8x - 35/8

Answer:

18 units²

Step-by-step explanation:

there are two ways to calculate the required area.

way 1.

the length of the side AB=7+2=9; the length of CD is 6-2=4 (note, CD⊥AC), then the required area is:

A=9*4/2=18.

way 2.

the coordinates of the vector AB=(0;-9), of vector AC=(4;-3).

The required area can be calculated using the formula: A=0.5*[ABxAC].

[tex]|A|=|\frac{1}{2}*\left[\begin{array}{ccc}0&-9\\4&-3\\\end{array}\right]|=|(-36):2|=18.[/tex]

Answer:

x = 0.15

Step-by-step explanation:

We have two equivalent ratios: 0.5 (or 1/2)/x = 2/0.6. It looks like our Giant One is 4/4, since 0.5 * 4 = 2. We can divide 0.6 by 4 to find the value of x. 0.6/4 = 0.15, so x = 0.15.

Step-by-step explanation:

The number is 15,238.1.

What is Number system?

A system of writing to express the number is called number system.

Given that;

The expression is;

''800 is 5 1/4% of number''

Now,

Let a number = x

Then, Expression is written as;

800 = 5 1/4% of x

800 = 21/4% × x

800 = 21/400 × x

x = 800 × 400 / 21

x = 15,238.1

Thus, The number is 15,238.1.

Answer:

x=-7

y=4

Step-by-step explanation:

I am assuming you want the values of x and y. We know that x=-2y+1 and 3x+8y=11. We can substitute the value of x (-2y+1) into the equation 3x+8y=11.

Therefore 3(-2y+1)+8y=11

Using the distributive property:

-6y+3+8y=11

2y+3=11

y=4

To solve for x, we will plug in 4 in -2y+1. So, x= -2(4)+1=-7.

Check: 3(-7)+8(4)=-21+32=11.

hence first one is last option. real numbers.

Using the normal distribution principle ; the probability that a randomly chosen chocolate is in the celebration box is 0.553

Zscore = (X - μ) ÷ σ

For X = 5 :

Zscore = (5 - 5.8) ÷ 1.3 = - 0.615

For X = 7 :

Zscore = (7 - 5.8) ÷ 1.3 = 0.923

Using a normal distribution table :

P(Z < 0.923) = 0.822

P(Z < - 0.615) = 0.269

P(Z < 0.923) - P(Z < - 0.615) = 0.822 - 0.269 = 0.553

Therefore, the probability of inclusion is 0.553.
