Answer:

y = -3/4x +1

Step-by-step explanation:

Parallel lines have the same slope, so the slope of the line you want is -3/4. The point-slope form of the equation of a line is useful when you have this information:

y -k = m(x -h) . . . . . . line with slope m through point (h, k)

y -(-2) = -3/4(x -4)

If you want slope-intercept form, you can rearrange this ...

y +2 = -3/4x +3

y = -3/4x +1 . . . . . . subtract 2 from both sides

Circle 1 has center (−4, 5) and a radius of 6 cm. Circle 2 has (2, −3) and a radius 9 cm.

zheka24 [161]

First translate the circle from (-4,5) to (2,-3) [ a translation of (+6, -8) ] by the transformation rule
(x,y)->(x+6, y-8)
the scale factor would be the ratio of the radii of image (circle 2) divided by that of preimage (circle 1)
=9/6=3/2

1) A grocer sold 5 kg of wheat flour at Rs 30 per kg and gained 20%. If he had sold

natita [175]

Answer:

given,

selling price (sp)=rs 5 ×30

=rs 150

now, gain %=20%

cost price (cp)=

$\frac{sp \times 100}{100 + gain\%}$

$= \frac{150 \times 100}{100 + 20}$

therefore cp= rs125

now,

again in 2nd case

sp= rs 27×5

therefore sp=rs 135

and cp= rs125

now, sp>cp so,

$gain\% = \frac{sp - cp}{cp} \times 100\%$

or, gain=

$= \frac{135 - 125}{125} \times 100\%$

therefore gain %= 8%.... is answer

hope it helps..

Solve for v. 3y+17 = 62 Simplify your answer as much as possible.

TEA [102]

Answer:

Hi there!

Your answer is 15

Step-by-step explanation:

3y+17=62

Step 1 : isolate y by subtracting 17 from both sides.

3y= 62-17

3y = 45

Step 2: Divide out the 3 so you have 1y.

3y=45

/3. /3

y= 15
