3(1-2x)=1/4(6x+9) what does x equal?
A) x=1/10
B) x=7/10
C) x=-12/7
D)x=-1/5
Answer:
A
Step-by-step explanation:
3(1-2x)=1/4(6x+9)
3-6x=1 1/2x+2 1/4
-2 1/4 -2 1/4
3/4-6x=1 1/2x
+6x +6x
3/4=7 1/2x
/7 1/2 /7 1/2
1/10=x
Answer:
A
Step-by-step explanation:
$3\left(1-2x\right)=\frac{1}{4}\left(6x+9\right)\quad:\quad x=\frac{1}{10}\quad\left(\mathrm{Decimal}:\quad x=0.1\right)$
3\left(1-2x\right)=\frac{1}{4}\left(6x+9\right)
$3\left(1-2x\right)$
$\mathrm{Apply\:the\:distributive\:law}:\quad\:a\left(b-c\right)=ab-ac$
$a=3,\:b=1,\:c=2x$
$=3\cdot\:1-3\cdot\:2x$
=3-6x
3-6x=\frac{3}{2}x+\frac{9}{4}
3-6x-3=\frac{3}{2}x+\frac{9}{4}-3
-6x=-\frac{3}{4}+\frac{3}{2}x
-6x-\frac{3}{2}x=-\frac{3}{4}+\frac{3}{2}x-\frac{3}{2}x
-\frac{15}{2}x=-\frac{3}{4}
2\left(-\frac{15}{2}x\right)=2\left(-\frac{3}{4}\right)
-15x=-\frac{3}{2}
\frac{-15x}{-15}=\frac{-\frac{3}{2}}{-15}
x=\frac{1}{10}

A coordinate grid with one line labeled y equals 3 x plus StartFraction 3 over 4 EndFraction. The line passes through points at (negative 1, negative 2) and (0, 1). Tomas wrote the equation y = 3x +y equals 3 x plus StartFraction 3 over 4 EndFraction.. When Sandra wrote her equation, they discovered that her equation had all the same solutions as Tomas’s equation. Which equation could be Sandra’s? –6x + y = negative 6 x plus y equals StartFraction 3 over 2 EndFraction. 6x + y = 6 x plus y equals StartFraction 3 over 2 EndFraction. –6x + 2y = negative 6 x plus 2 y equals StartFraction 3 over 2 EndFraction. 6x + 2y = 6 x plus 2 y equals StartFraction 3 over 2 EndFraction.
Answer:
the answer is c
mark me brainiest plz
Step-by-step explanation:
Sandara equation is -6x + 2y = 3/2.
The correct option is (C)
What is graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
Given:
Tomas equation:
y = 3x + 3/4..........(1)
-3x + y = 3/4
and, if we multiply by 2
-6x + 2y = 3/2...............(2)
As, equation (1) and (2) are equal.
So, Sandara equation is -6x + 2y = 3/2.

What is a transformation of a shape?A point, line, or mathematical figure can be converted in one of four ways, and each has an effect on the object's structure and/or position.
Rotation does not change the shape and size of the geometry. But changes the orientation of the geometry.
The preimage is bigger than the image. That means the scale factor is less than one. Then the scale factor is given as,
Scale factor = 2 / 4
Scale factor = 1/2
The preimage is rotated by 180° about the origin to form the image.
The sequence of transformations will be dilated with a scale factor of 1/2 and rotated by 180°. Then the correct option is C.

Write a linear function f with f(5)=−1 and f(0)=−5
Answer:
Ok
Step-by-step explanation:
Answer:
If you give some thought to the given facts, you will realize that f(5) = -1 means point (5,-1).
Similarly, there's a second point given.
Having two points enables you to find slope.
Then you can use the Point Slope form of the equation to write a formula for the line, involving x and y by using either of the ordered pairs as (x1, y1).
Solve for y, in terms of x, and then relabel that f(x)...because in graphs, y = f(x

On a coordinate plane, a dashed straight line with negative slope goes through (negative 2, 2) and (0, negative 1). Everything to the left of the line is shaded.
Answer: Its C
Step-by-step explanation:
On a coordinate plane, a dashed straight line with a negative slope goes through (negative 2, 0) and (0, negative 1). Everything to the right of the line is shaded. Option C is correct.
It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
It is given that the inequality is,
2x + 3y > –3
A dashed straight line with a negative slope passes between (negative 2, 0) and the graph in the coordinate plane (0, negative 1). Shaded areas around the line to the right.
Thus, on a coordinate plane, a dashed straight line with a negative slope goes through (negative 2, 0) and (0, negative 1). Everything to the right of the line is shaded. Option C is correct.

What is a coordinate system?A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A function is defined as the expression that set up the relationship between the dependent variable and independent variable.
The graph of the function is represented on the coordinate plane. In the graph, the values under the mode will always be positive. And the values of the function g(x) = |x – 1| + 3 start from the coordinate ( 1, 3). The graph of the function g(x) = |x – 1| + 3 is attached with the answer below.
Therefore, the equation that represents the function graphed on the coordinate plane is g(x) = |x – 1| + 3. The correct option is C.
