Answer:

5/4 is the slope

Step-by-step explanation:

y= 5/4c- 7/4

This is in the slope intercept form

y = mx+b where m is the slope and b is the y intercept

5/4 is the slope and -7/4 is the y intercept

Answer:

5/4

Step-by-step explanation:

This equation is in slope intercept form (y=mx=b) so when interpreting the information we see that the slope is 5/4.

y = y

m = slope

x = x or in this case they use c

b = y intercept

This equation represents a line that intercepts at -7/4 and has a slope of 5/4. This can be checked by plugging in any point on the line for x and y.

Hope this helps!

- What is the area of the figure below? Use 3.14 for T. 7 cm 22 cm 18 cm

ziro4ka [17]

Answer: $\Large\boxed{Total~area=586.17~cm^2}$

Step-by-step explanation:

<h2>PART I: Find the area of the triangle</h2>

Given information

$Height=7~cm$

$Base=18~cm$

Given formula

$A=b\times h\times\dfrac{1}{2}$

$A=Area\\b=base\\h=height\\$

Substitute values into the formula

$A=(7)\times (18)\times\dfrac{1}{2}$

Simplify by multiplication

$A=(7)\times 9$

$A=63~cm^2$

<h2>PART II: Find the area of the rectangle</h2>

Given information

$Height = 18~cm$

$Base=22~cm$

Given formula

$A=b\times h$

$A=Area\\b=base\\h=height\\$

Substitute values into the formula

$A=(22)\times (18)$

Simplify by multiplication

$A=396~cm^2$

<h2>PART III: Find the area of the half-circle</h2>

Given information

Diameter = 18 cm

Given formula

$A=(\dfrac{d}{2} )^2\times \pi \div2$

$A=Area\\d=diameter$

Substitute values into the formula

$A=(\dfrac{18}{2} )^2\times (3.14) \div2$

Simplify the fraction

$A=(9 )^2\times (3.14) \div2$

Simplify the exponents

$A=81\times (3.14) \div2$

Simplify by multiplication

$A=254.34\div2$

Simplify by division

$A=127.17~cm^2$

<h2>PART IV: Find the total area</h2>

Given formula

$Total~area=Triangle+Rectangle+circle~(half)$

Substitute values into the formula

$Total~area=(63)+(396)+(127.17)$

Simplify by addition

$Total~area=459+(127.17)$

$\Large\boxed{Total~area=586.17~cm^2}$

Hope this helps!! :)

Write 5/10 in three equivalent forms

krek1111 [17]

equivalent fractions are fractions which have the same value.

equivalent fractions all have the same simplified form

we can write equivalent fractions by multiplying both numerator and denominator by the same number. We can also write equivalent fractions by dividing both numerator and denominator by the same number

so 5/10

we can get the equivalent fractions by multiplying by a common number

when we multiply by 2

$\frac{5}{10}* 2= \frac{5*2}{10*2} = \frac{10}{20}$

when we multiply by 3

$\frac{5}{10}* 3 = \frac{5*3}{10*3} = \frac{15}{30}$

when we multiply by 4

$\frac{5}{10} *4 = \frac{5*4}{10*4} = \frac{20}{40}$

the three equivalent fractions are

10/20 , 15/30, 20/40

9x-2y=11 5x-2y=15 what is the solution to the above system of equations ASAP

natali 33 [55]

9x - 2y = 11 ... (i)

5x - 2y = 15 ... (ii)

Subtracting equation (ii) from (i) we get;

4x + 0 = -4

4x=-4 , x = -1

Replacing x = -1 in equation (i) we get;

9(-1) - 2y = 11

-9 - 2y = 11

-2y = 20

y = 20 ÷ -2 = -10

The solution to the system of equations is (-1,-10).
