Answer:

m=2-2

m=0

Step-by-step explanation:

U need to do substitution

So u carry both 2 from that side to cross the equal to sign. One becomes positive because it is carrying a negative sign at the other side

A quadratic function is given. f(x) = 1 + x − 7 x2 (a) Use a graphing device to find the maximum or minimum value of the quadrat

Virty [35]

Answer:

a) $P (x,y) \approx (0.1,1.05)$ , b) $P(x,y) = (0.07,1.04)$ .

Step-by-step explanation:

a) The graphic is enclosed to the problem. By visual inspection, an absolute maximum is found.

$P (x,y) \approx (0.1,1.05)$

b) The exact method consists in the application of the First and Second Derivative Tests. First and second derivatives are, respectively:

$f'(x) = 1 - 14\cdot x$

$f''(x) = -14$

The First Derivative Test consists in equalizing the first derivative to zero and solving the expression:

$1 - 14\cdot x = 0$

$x = 0.07$

According to the second derivative, the critical point leads to a maximum. The remaining component is determined by evaluation the polynomial:

$y = 1 +0.07-7\cdot (0.07)^{2}$

$y = 1.04$

The exact solution is $P(x,y) = (0.07,1.04)$ , indicating that graphic solution leads to a good approximation.

On the grid draw the graph of x + 2y =7

Elena-2011 [213]

Answer:

See attachment for graph

Step-by-step explanation:

Given

$x + 2y = 7$

Required

Draw the graph

First, we identify at least 2 possible values of x and y

Let $x = 1$

Solve for y

$x + 2y = 7$

$1 + 2y = 7$

$2y = 6$

$y = 3$

So, a point is: $(1,3)$

Let $x = 3$

Solve for y

$x + 2y = 7$

$3 + 2y = 7$

$2y = 7 -3$

$2y = 4$

$y = 2$

So, another point is: $(3,2)$

<em>Plot </em> $(1,3)$ <em> and </em> $(3,2)$ <em> on the graph, then draw a straight line through both points</em>
