Answer:

y-4=5(x+2)

Step-by-step explanation:

We want to find the equation in point-slope form of the line that passes through the point (-2,4) and has slope  m=5.

The point-slope form is given by the formula;

y-y_1=m(x-x_1)


where m=5 is the slope and

(x_1,y_1)=(-2,4) is a point on the line,


We substitute the values into the formula to obtain;

The required equation is  y-4=5(x+2)

For what values of x is the area of the rectangle greater than the perimeter?
soldier1979 [14.2K]
Area = 7(x + 2) = 7x + 14
Perimeter = 2(7 + x + 2) = 2(9 + x) = 18 + 2x
7x + 14 > 18 + 2x
7x - 2x > 18 - 14
5x > 4
x > 4/5

Solve the following Simultaneous equation<br>Using any suitable method<br> x+6y=2, 3x +2y =10​
uranmaximum [27]

Answer:

x = 0.5

y = -1/4 or -0.25

Step-by-step explanation:

x + 6y = 2

3x + 2y = 10

Multiply a number by any of the equations to get numbers of the same variable

3x + 18y = 6

3x + 2y = 10

3x - 3x = 0

NB: subtract evenly if u subtract down from top make sure u subtract down from top throughout

16y = -4

16y/16 = -4/16

y = -1/4 or -0.25

to find the x value, any where you see y u put in the y value(-0.25)

So u'll pick just one of the equations above

x + 6(0.25) = 2

x + 1.5 = 2

x = 1.5 + 2

x = 0.5

Add. <br> (−2+6x^3−3x^2)+(4x^3−5+x^2)
Gemiola [76]

Answer:

10x^3 - 2x^2 -7

Step-by-step explanation:

To subtract polynomials, you want to subtract the biggest exponent from the first polynomial to the second

so 6x^3 + 4x^3 and that would be 10x^3

then -3x^2 + x^2 and the negative is larger so it would be -2x^2

and finally -2 + -5 and that is -7

hope this helps! :)
