16 is 25 percent of the number so if you multiply 4 on top and bottom, you get 64.

4x-5y=-15 <br> 7x-2y=21 <br> X=<br> Y=

Helen [10]

Answer:

The values of x and y to the given equations are x=5 and y=7

Step-by-step explanation:

Given equations are $4x-5y=-15\hfill (1)$

$7x-2y=21\hfill (2)$

To solve the given equations by elimination method :

Multiply the equation (1) into 2 we get

$8x-10y=-30\hfill (3)$

Multiply the equation (2) into 5 we get

$35x-10y=105\hfill (4)$

Now subtracting the equations (3) and (4) we get

$8x-10y=-30$

$35x-10y=105$

_________________

$-27x=-135$

$x=\frac{135}{27}$

Therefore x=5

Now substitute the value of x=5 in equation (1) we get

4(5)-5y=-15

20-5y=-15

-5y=-15-20

-5y=-35

$y=\frac{35}{5}$

Therefore y=7

The values are x=5 and y=7

How do I find the form of an equation. Is it Slope intercept form standard form or point slope form.

natulia [17]

Answer:

Step-by-step explanation:

slope intercept is y=mx+b

standard form is Ax+By=C.

point slope form is y-y₁=m(x-x₁)

so y=2/3x+2 is slope intercept

Answer:

Step-by-step explanation:

X^4+x=0

X(X^3+1)=0

X(X+1)(x^2-x+1)=0

X=0, x=-1, x=(1+3^1/2i)x=(1-3^1/2i）
