Answer:

The value of x is -10.

Step-by-step explanation:

Given : Expression $3x-8=\frac{8x+4}{2}$

To find : What is the value of x?

Solution :

Step 1 - Write the expression,

$3x-8=\frac{8x+4}{2}$

Step 2 - Cross multiply,

$6x-16=8x+4$

Step 3 - Take like terms together,

$6x-8x=4+16$

Step 4 - Solve,

$-2x=20$

$x=-\frac{20}{2}$

$x=-10$

Therefore, The value of x is -10.

what is the equation, in slope-intercept form, of the line that is perpendicular to the line y – 4 = –2/3 (x – 6) and passes thr

velikii [3]

For perpendicular lines, m2 = -1/m1 = -1/(-2/3) = 3/2 [m1 = -2/3]

Required equation is y + 2 = 3/2(x + 2) => y + 2 = 3/2 x + 3 => y = 3/2 x + 1

Daniel guesses that he scored a 95 on his science test.His actual score is 91. What is the percent error in Daniel's guess? Roun

Kamila [148]

1) Formula for the percent of error:

                               [estimated measure - real measure]
Percent of error = ---------------------------------------------------- x 100
                                            real measure

2) Calculations:

                             [95 - 91]
Percent error = --------------- x 100 = 4.4 %
                                 91

Answer: 4.4%

Divide (x^2+9x+19)÷(x+5)

gayaneshka [121]

Since this can’t be factored easily, you have to use synthetic division. This makes the answer x+4+(-1/x+5)
