9.50*30= 285
9.50*10.5=99.75
9.50*2*5= 95
Total: 479.75

Answer:

It looks like the third one, C

Step-by-step explanation:

Every time c increases by 1, d increases by 2

That means the slope will be 1/2

That means the slope is positive

Answer:

<em>Answer is option</em><em> </em><em>b</em><em>)</em><em> </em>

<em> ${(x - 3)}^{2} + {(y - 4)}^{2} = 400$ </em>

<em>Your</em><em> </em><em>guess</em><em> </em><em>was</em><em> </em><em>right</em><em>.</em>

Step-by-step explanation:

$the \: question \: states \: that \: \\ distance \: between \: two \: points \: is \: 20 \: units \: \\ and \: the \: two \: points \: are \: (x,y) \: \: and \: \: (3 ,- 4) \\ distance \: formula \\ = \sqrt{ {(x1 - x2) }^{2} + {(y1 - y2)}^{2} } \\ on \: substituting \: the \: values \: in \: formula \\ 20 = \sqrt{ {(x - 3)}^{2} + {(y - ( - 4))}^{2} } \\ 20 = \sqrt{ {(x - 3)}^{2} + {(y + 4)}^{2} } \\ now \: squaring \: on \: both \: sides \\ 400 = {(x - 3)}^{2} + {(y + 4)}^{2} \\ hence \: the \: answer \: is \: option \: b)$

What is the solution of the system?

Serjik [45]

Answer:

(-13,-4)

Step-by-step explanation:

4x-8y=-20

9x+113=y

Substitute in y for 9x+113

4x-8y=-20

Substitute

4x-8(9x+113)=-20

Simplify

4x-72x-904=-20

Simplify

-68x-904=-20

Additive Prop. of Equality

-68x-904+904=-20+904

Simplify

-68x=884

Isolate the variable(x)

<u>-68x</u>=<u>884</u>

-68x -68x

Simplify

x=-13

Solve for y

9x+113=y

9(-13)+113=y

-117+113=y

-4=y

Check

4x-8y=-20

4(-13)-8(-4)=-20

-52+32=-20

-20=-20

9x+113=y

9(-13)+113=-4

-117+113=-4

-4=-4

I need to know how to find the value of x

anzhelika [568]

x = 15°

The angle of a straight line is 180°.

37 + 9x + 8 = 180
9x + 45 = 180
9x = 135
x = 15°

Three collinear points on the coordinate plane are r(x,y), s(x+8h, y+8k), and p (x+6h, y+6k)

Karo-lina-s [1.5K]

Answer:

A. $\frac{RP}{SP}=3$

B. $\frac{RP}{RS}=\frac{3}{4}$

Step-by-step explanation:

<u><em>The complete question is</em></u>

Three collinear points on the coordinate plane are R(x, y), S(x+8h, y+8k), and P(x+6h, y+6k).

<em>Part A: Determine the value of RP/SP</em>

<em>Part B: Determine the value of RP/RS</em>

we know that

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

we have

$R(x,y),S(x+8h,y+8k) and P(x+6h,y+6k)$

Part A.We have to find the value of $\frac{RP}{SP}$

step 1

Find the distance RP

$R(x,y),P(x+6h,y+6k)$

substitute the values in the formula

$RP=\sqrt{(x+6h-x)^2+(y+6k-y)^2}$

$RP=\sqrt{36h^2+36 k^2}$

$RP=6\sqrt{h^2+k^2}$

step 2

Find the distance SP

$S(x+8h,y+8k),P(x+6h,y+6k)$

substitute the values in the formula

$SP=\sqrt{(x+6h-x-8h)^2+(y+6k-y-8k)^2}$

$SP=\sqrt{4h^2+4k^2}$

$SP=\sqrt{4(h^2+k^2)}$

$SP=2\sqrt{h^2+k^2}$

step 3

<em>Find the ratio RP/SP</em>

$\frac{RP}{SP}=\frac{6\sqrt{h^2+k^2}}{2\sqrt{h^2+k^2}}$

$\frac{RP}{SP}=3$

Part B. We have to determine the value of $\frac{RP}{RS}$

step 1

Find the distance RS

$R(x,y),S(x+8h,y+8k)$

$RS=\sqrt{(x+8h-x)^2+(y+8k-y)^2}$

$RS=\sqrt{64h^2+64k^2}$

$RS=\sqrt{64(h^2+k^2)}$

$RS=8\sqrt{h^2+k^2}$

step 2

<em>Find the ratio RP/RS</em>

$\frac{RP}{RS}=\frac{6\sqrt{h^2+k^2}}{8\sqrt{h^2+k^2}}$

$\frac{RP}{RS}=\frac{3}{4}$
