Find the inequality for this graph

Arada [10]

ANSWER

$y \geqslant - 2x - 5$

EXPLANATION

First we need to find the equation of the boundary line which passes through (-1,-3) with a y-intercept of -5.

The slope of this line is

$m = \frac{ -5 - - 3}{0 - - 1} = - 2$

The equation of this line is

$y = - 2x - 5$

Since the boundary line is solid and the upper half plane is shaded the required inequality is

$y \geqslant - 2x - 5$

A new alloy is made by mixing 72 grams of iron with 9 grams of zinc. How many grams of iron are required to make the alloy when

iren2701 [21]

1152 grams of iron are required to make the alloy when combined with 144 grams of zinc

Step-by-step explanation:

We will use the proprtion to solve the problem

Let x2 be the quantity of iron when combined with 144 grams of zinc

So,

zinc in first alloy = z1 = 9 gm

Iron in first alloy = x1 = 72 gm

Zinc in second alloy = 144 gm

So,

$x_1:z_1::x_2:z_2\\72:9:: x_2 : 144\\\frac{72}{9} = \frac{x_2}{144}\\8 = \frac{x_2}{144}\\x_2 = 144*8\\x_2 = 1152$

Hence,

1152 grams of iron are required to make the alloy when combined with 144 grams of zinc
