4 0

Answer:

$x = 40$

$y = 5$

Step-by-step explanation:

$4x = 2x+80\\2x = 80\\x = 40$

Edit: Solve for Y

A straight line is 180 degrees so one side (the x side) is 160°, The Y side is 20, and you can work backwards by -

$8y - 20 = 20\\8y = 40\\y = 5$

Which function has the graph with the greatest y-intercept?

Lubov Fominskaja [6]

Answer:

The greatest y-intercept c = 6

Step-by-step explanation:

we know that

slope-intercept form y = mx +c

a) Given that f(x) = $6x + \frac{1}{6}$

$y = 6x + \frac{1}{6}$

comparing y = mx +c

slope of the line m = 6 and Y - intercept c= 1/6

b) Given that f(x) = $6x -6$

y = 6x -6

comparing y = mx +c

slope of the line m = 6 and Y - intercept c= -6

Given that f(x) = $\frac{1}{6} x +6$

y = $\frac{1}{6} x +6$

comparing y = mx +c

slope of the line m = $\frac{1}{6}$ and Y - intercept c= 6 ( greatest intercept)

Given that 6 k(x) = x

k(x) = $\frac{1}{6} x$

y = $\frac{1}{6} x$

comparing y = m x +c

The slope of the line m = $\frac{1}{6}$ and Y-intercept c=0

Final answer:-

The greatest y-intercept c = 6

Art wants to cover an isosceles triangle with a height of 9 centimeters and a base of 7 centimeters in fabric. How much fabric d

s2008m [1.1K]

Answer:

31.5 cm²

Step-by-step explanation:

Calculate area of a triangle with this formula:

Area = $\frac{1}{2}$ base * height

Substitute in known values

Area = $\frac{1}{2}$ 7 * 9

Multiply 7 by 1/2

Area = 3.5 * 9

Multiply

Area = 31.5 cm²

Hope this helps :)

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..
