What is the value for x in the equation 3/4x-1/2(2-1/2x)=1/3
IgorLugansk [536]
- - We are finding the value of "X" 

"x" Is representing an unknown number, one that we must solve to find.

• The first step is going to be distributing our equation. 

\frac{3}{4} x + \frac{1}{4} x + - 1 = \frac{1}{3}
↓ ↓ ↓ ↓ ↓
( \frac{3}{4} x + \frac{1}{4} x )+ (- 1) = \frac{1}{3}


• Now we are going to do like terms by combining them.

x + -1 =  \frac{1}{3} 

x - 1 =  \frac{1}{3}

• Now need to add "1" to both sides of our equation to get our final answer.

x-1+1= \frac{1}{3} -1

- - Final answer; x = \frac{4}{3}

What is the equation of a line that is perpendicular to -x+2y=4 and passes through the point (-2,1)?
Usimov [2.4K]
-x + 2y = 4
2y = x + 4
y = 1/2x + 2.....slope here is 1/2. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So the slope we need is -2 (see how I flipped the slope and changed the sign)

y = mx + b
slope(m) = -2
(-2,1)...x = -2 and y = 1
now we sub and solve for b, the y int
1 = -2(-2) + b
1 = 4 + b
1 - 4 = b
-3 = b

so ur perpendicular line is : y = -2x - 3

The three inside angles of a triangle equal 180 degrees,

If one angle is 110, subtract that from 180 to find the total of the other two.

180 - 110 = 70


The other two angles equal 70 degrees.

Write the equation whose roots are 6 and 1, and whose leading coefficient is 4.
Black_prince [1.1K]

Answer:

4(x-6)(x-1) = 0

Standard form: 4x^2-28x+24=0

Step-by-step explanation:

First, let's write an equation where the roots are 6 and 1.

To do that, we can use the intercept form <em>a(x-p)(x-q) = 0</em>, where <em>a</em> is the leading coefficient, and <em>p </em>and <em>q</em> are the roots.

We can therefore plug what we know into this equation:

4(x-6)(x-1) = 0
