8.7x – 1.9x = 116.96 Help please

Mathematics
1 answer:
jok3333 [9.3K]2 years ago
3 0

Answer: x = 17.2

Step-by-step explanation:

So we can combine 8.7x and 1.9x as they are considered like terms.

So basically since they have the same base of x we can disregard the x when subtracting.

So its more like 8.7-1.9 which = 6.8

Now add the x back

So it is 6.8x = 116.96

Now we need to isolate the variable.

To do this we need to divide the 6.8 on both sides.

So x = 116.96/6.8

x = 17.2

Using Rigid motion, explain in detail, why triangle ABC must be congruent to triangle DEF
weeeeeb [17]
Using rigid motion, both of these triangles will be congruent. The reason is because rigid motions include reflections, translations, and rotations.

None of these transformations will affect the size or shape of the figure, therefore keeping them congruent.

Dy/dx = (cos x) e^(y+sinx) and y = 0 when x = 0. find the original equation
Korvikt [17]
Find the general solution by separating the variables then integrating: 
dy / dx = cosx℮^(y + sinx) 
dy / dx = cosx℮ʸ℮^(sinx) 
℮^(-y) dy = cosx℮^(sinx) dx 
∫ ℮^(-y) dy = ∫ cosx℮^(sinx) dx 
-℮^(-y) = ℮^(sinx) + C 
℮^(-y) = C - ℮^(sinx) 
-y = ln[C - ℮^(sinx)] 
y = -ln[C - ℮^(sinx)] 

Find the particular solution by solving for the constant: 
When x = 0, y = 0 
-ln(C - 1) = 0 
ln(C - 1) = 0 
C - 1 = 1 
C = 2 
<span>y = -ln[2 - ℮^(sinx)]

1<br> What are the basic tools of Euclidean geometry?
AVprozaik [17]

Answer:

The straightedge and the compass. The name is due to the fact that connecting points with segments, prolonging segments and drawing circles with a given center and a given radius are the basic geometric constructions described in the first three Euclidean postulates.

What are the solutions of 3x2 + 14x + 16 = 0?
Leya [2.2K]

Answer:

Given the equation: 3x^2+14x+16=0

The general equation of quadratic formula for ax^2+bx+c=0 where a, b and c are constant;

then, the solution for this equation  is given by;

&#10;x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}              ......[1]

From the equation, 3x^2+14x+16=0 we have

a =2, b=14 and c=16

Substitute these values in [1] to solve for x;

&#10;x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}=\frac{-14\pm\sqrt{(14)^2-4(3)(16)}}{2(3)}              

or

x=\frac{-14\pm\sqrt{196-192}}{6} =\frac{-14\pm\sqrt{4}}{6}

Simplify:

x=\frac{-14\pm\sqrt{4}}{6} =\frac{-14\pm 2}{6}

then,

x=\frac{-14+2}{6} =\frac{-12}{6} =-2 and

x=\frac{-14-2}{6} =\frac{-16}{6} =\frac{-8}{3}

Therefore, the solutions for the given equation is; x =-2 and x =-\frac{8}{3}
