Answers

Answer 1

Answer:

40%

Step-by-step explanation:

just take a number, for example, 1, and do the math.

1 - 30% = 0.7.

1 - 50% = 0.5.

0.7 / 0.5 = 1.4.

thus the answer is 40%.

Solve for x. Enter your answer in interval
notation using grouping symbols.
x2 + x < 20

Answers

Answer:

x<18

Step-by-step explanation:

2+x<20

Answer:

(-5, 4)

Step-by-step explanation:

x^2 + x < 20 can be rewritten as a quadratic in standard form: x^2 + x - 20 < 0. Recognize that the graph of x^2 + x - 20 is that of a parabola that opens up. Because the y-intercept (0, -20) is below the x-axis, we know for certain tht the graph intersects the x-axis in two places. Our job is to determine the two horizontal intercepts, which in turn determine the solution set.

x^2 + x - 20 = 0 factors as follows: (x + 5)(x - 4) = 0, whose roots are -5 and 4.

These two roots form 3 intervals: (-infinity, -5), (-5, 4) and (4, infinity). We now must identify on which intervals x^2 + x - 20 is less than 0 (that is, on which intervals the graph is below the x-axis). Choose three test values for x: the first could be -6 (which is in the set (-infinity, -5) ); x^2 + x - 20 is + there, and so the graph is above the x-axis and x^2 + x - 20 is positive. Reject this.

Next, test x = 0; x^2 + x - 20 is negative there, meaning that x^2 + x - 20 < 0 and that x^2 + x < 20. Thus, the solution is (-5, 4). It can be shown that x^2 + x - 20 is positive again for x-values within the interval (4, infinity).

Evaluating

5 donuts and 2 cups of hot Chocolate costs 24$. 2 donuts and 3 cups of hot chocolate costs 14$.How much does each donut and each cup of hot chocolate cost

Answers

Answer:cost of each donut =$4

and cost of each cup of hot chocolate =$2

Step-by-step explanation:

Step 1

Let donuts be represented as d

and cups of hot chocolate be rep as c so that

5 donuts and 2 cups of hot Chocolate costing 24$ will be expressed as

5 d+ 2 c= 24

And 2 donuts and 3 cups of hot chocolate costing 14$ will be expressed as

2d +3 c= 14

Step 2

Using elimination method,Multiply equation 1 by 3 and equation 2 by 2

15d+ 6c= 72----equation 3

4d+ 6c= 28-----equation 4

Subtracting equation 4 from equation 3 gives us

11 d=44

d= 44/11

d= 4

To find c, using equation 1

5 d+ 2 c= 24

5 x 4+ 2c=24

20+2c=24

2c=24-20

2c=4

c=4/2 =2

cost of each donut =$4

and cost of each cup of hot chocolate =$2

Answers

Answer:

y = 23x - 136

Step-by-step explanation:

Since the lines are parallel, they have the same slope. So, the slope of the new line is 23 as well.

Now we have: y = 23x + b

plug in the points that are on this line (6,2) :

2 = 23 x 6 + b

2 = 138 +b

From room to room they went, hand in hand, lifting here, opening there, making surea ghostly couple.Here we left it, she said. And he added, Oh, but here too! Its upstairs, she murmured. And in the garden, he whispered Quietly, they said, or we shall wake them.But it wasnt that you woke us. Oh, no.Theyre looking for it; theyre drawing the curtain, one might say, and so read on a page or two. Now theyve found it, one would be certain, stopping the pencil on the margin. And then, tired of reading, one might rise and see for oneself, the house all empty, the doors standing open, only the wood pigeons bubbling with content and the hum of the threshing machine sounding from the farm.What did I come in here for? What did I want to find? My hands were empty. Perhaps its upstairs then? The apples were in the loft. And so down again, the garden still as ever, only the book had slipped into the grass.But they had found it in the drawing room. Not that one could ever see them. The window panes reflected apples, reflected roses; all the leaves were green in the glass. If they moved in the drawing room, the apple only turned its yellow side.Yet, the moment after, if the door was opened, spread about the floor, hung upon the walls, pendant from the ceilingwhat? My hands were empty. The shadow of a thrush crossed the carpet; from the deepest wells of silence the wood pigeon drew its bubble of sound. Safe, safe, safe, the pulse of the house beat softly. The treasure buried; the room . . . the pulse stopped short. Oh, was that the buried treasure? A moment later the light had faded. Out in the garden then? But the trees spun darkness for a wandering beam of sun. So fine, so rare, coolly sunk beneath the surface the beam I sought always burnt behind the glass. Death was the glass; death was between us; coming to the woman first, hundreds of years ago, leaving the house, sealing all the windows; the rooms were darkened. He left it, left her, went North, went East, saw the stars turned in the Southern sky; sought the house, found it dropped beneath the Downs. Safe, safe, safe, the pulse of the house beat gladly. The Treasure yours.The wind roars up the avenue. Trees stoop and bend this way and that. Moonbeams splash and spill wildly in the rain. But the beam of the lamp falls straight from the window. The candle burns stiff and still. Wandering through the house, opening the windows, whispering not to wake us, the ghostly couple seek their joy. Here we slept, she says. And he adds, Kisses without number. Waking in the morning Silver between the trees Upstairs In the garden When summer came In winter snowtime The doors go shutting far in the distance, gently knocking like the pulse of a heart.Nearer they come; cease at the doorway. The wind falls, the rain slides silver down the glass. Our eyes darken; we hear no steps beside us; we see no lady spread her ghostly cloak. His hands shield the lantern. Look, he breathes. Sound asleep. Love upon their lips.Stooping, holding their silver lamp above us, long they look and deeply. Long they pause. The wind drives straightly; the flame stoops slightly. Wild beams of moonlight cross both floor and wall, and, meeting, stain the faces bent; the faces pondering; the faces that search the sleepers and seek their hidden joy.Safe, safe, safe, the heart of the house beats proudly. Long years he sighs. Again you found me. Here, she murmurs, sleeping; in the garden reading; laughing, rolling apples in the loft.
