x=9 because the triangle is equilateral which means every side is equal to 60. When you do the math you get 7x-3=60 which is 7x=63 and 63/7=9

x = 9

The triangle has all 3 sides congruent and is thus an equilateral triangle.

Each angle = 60°

equate 7x - 3 = 60 and solve for x ( add 3 to both sides )

7x = 63 (divide both sides by 7 )

x = $\frac{63}{7}$ = 9

Which linear equation below represents the line that goes through the point (3.4) and has a slope of 2?

Ad libitum [116K]

Answer:

Linear equation with a slope of 2 that goes through the point (3, 4) is $y = 2\cdot x -2$ .

Step-by-step explanation:

From statement we know the slope of the line and a point contained in it. Using the slope-point equation of the line is the quickest approach to determine the appropriate equation, whose expression is:

$y-y_{o} = m \cdot (x-x_{o})$

Where:

$m$ - Slope, dimensionless.

$x_{o}$ , $y_{o}$ - Components of given point, dimensionless.

$x$ , $y$ - Independent and dependent variable, dimensionless.

If we know that $m = 2$ , $x_{o} = 3$ and $y_{o} = 4$ , the linear equation is found after algebraic handling:

1) $y-4 = 2\cdot (x-3)$ Given

2) $y = 2\cdot (x-3) +4$ Compatibility with Addition/Existence of Additive Inverse/Modulative Property

3) $y = 2\cdot x -2$ Distributive Property/ $(-a)\cdot b = -a\cdot b$ /Definition of sum/Result

Linear equation with a slope of 2 that goes through the point (3, 4) is $y = 2\cdot x -2$ .

If on the unit circle C, the distance from P(1, 0) to the point T ( 4/5 , 3/5 ) is x, determine the coordinates of the point at

AveGali [126]

Answer:

$(\frac{4}{5}, -\frac{3}{5} )$

Step-by-step explanation:

The point P(1,0) and T $(\frac{4}{5}, \frac{3}{5} )$ are on the unit circle C and the arc length from P to T is x.

Let us assume that point P - x i.e. the point obtained by moving clock wise direction along the circle from P is T'.

Because of the symmetry of the circle about the coordinate axes, the x-coordinate of point T' will be $\frac{4}{5}$ and the y-coordinate will be $-\frac{3}{5}$ .

So, coordinates of T' are $(\frac{4}{5}, -\frac{3}{5} )$ .

Here we must notice that point T' is the reflection point of T with respect to X-axis. (Answer)
