Graph the solution of the system of linear inequalities.<br> y≤−4x−4<br> y≥x+2
tamaranim1 [39]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

y\leq -4x-4 ----> inequality A

The solution of the inequality A is the shaded area below the solid line y=-4x-4

The y-intercept of the solid line is -4

The x-intercept of the solid line is -1

The slope of the solid line is negative

y\geq x+2 ----> inequality B

The solution of the inequality B is the shaded area above the solid line y=x+2

The y-intercept of the solid line is 2

The x-intercept of the solid line is -2

The slope of the solid line is positive

The solution of the system of inequalities is the shaded area between the two solids line

see the attached figure

stephen and bridget win some money and share it in the ratio 5:2. stephen gets £65. how much does bridget get
katen-ka-za [31]

Answer:

Bridget will get the amount as £26.

Step-by-step explanation:

Given:

Amount Stephen gets = £65

Amount shared in ratio = 5:2

We need to find the amount Bridget gets.

Solution:

Let the common factor in the ratio be 'x'.

Amount Stephen gets = 5x

Amount Bridget gets = 2x

But we know that;

Amount Stephen gets = £65

so we can say that;

5x=65

Now dividing both side by 5 we get;

\frac{5x}{5}=\frac{65}{5}\\\\x=13

So now we get;

Amount Bridget gets = 2x=2\times 13 = \£26

Hence Bridget will get the amount as £26.

the snake slithered 2.25 m before resting on a rock. Then the snake slithered twice as far as it did before, to catch a rat. Whe
NemiM [27]

Answer:

Step-by-step explanation:

2.25m + 2(2.25m) + 90 cm =

2.25m + 4.50m + 90 cm

6.75m + 90 cm

1 cm = 0.01m...so 90 cm = 90 * 0.01 = 0.9m

6.75m + 0.9m = 7.65m <===
