Step-by-step explanation:

❁ $\underline{ \underline{ \large{ \tt{ \: G \: I \: V \: E \: N}}}} :$

Marked price ( MP ) = $ 50
Discount % ( Dis % ) = 30 %

❁ $\underline{ \underline{ \large{ \tt{ T \: O \: \: F \: I \: N \: D}}}} :$

Discount amount = ?

❁ $\underline{ \underline{ \large{ \tt{S \: O \: L \: U \: T \: I \: O \: N}}}} :$

$\boxed{ \sf{Discount \: amount = Dis\% \: of \:MP}}$

Plug the known values :

➝ $\large{ \tt{30\% \: of \: 50}}$

Convert 30% to fraction. For that divide 30 by 100 and remove the percentage symbol.

➝ $\large{ \tt{ \frac{30}{100} \times 50}}$

➝ $\large{ \tt{ \bold{ \$ \: 15}}}$

$\large{ \underline{ \pink {\boxed{ \boxed{ \tt{Our \: final \: answer : \boxed{ \underline{ \bold{ \tt{ \bold{ \$ \: 15}}}}}}}}}}}$

Hope I helped ! ♡

Have a wonderful day! ツ

Solve the following simultaneous linear equations.<br>2x + y = 5<br>4x – 3y = -10

Jet001 [13]

Answer:

(1/2,4)

Step-by-step explanation:

First, determine y in first equation: 2x+y=5 or y=5-2x

replace value of y determined in first equation (5-2x) into 2nd equation

4x-3(5-2x)=-10

4x-15+6x=10

10x=5

x=1/2

put value of x into either equation to solve for y so

2(1/2)+y=5

1+y=5

y=4

answer: x=1/2, y=4

check answer by substituting x and y into either equation:

4x-3y=-10

4(1/2)-3(4)=-10

2-12=-10

-10=-10

2x+y=5

2(1/2)+4=5

1+4=5

5=5

At what point on the parabola y = 3x^2 + 2x is the tangent line parallel to the line<br> y = 10x −2?

oksian1 [2.3K]

Answer:

( $\frac{4}{3}$ , 8 )

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 10x - 2 ← is in slope- intercept form

with slope m = 10

Parallel lines have equal slopes

then the tangent to the parabola with a slope of 10 is required.

the slope of the tangent at any point on the parabola is $\frac{dy}{dx}$

differentiate each term using the power rule

$\frac{d}{dx}$ (a $x^{n}$ ) = na $x^{n-1}$ , then

$\frac{dy}{dx}$ = 6x + 2

equating this to 10 gives

6x + 2 = 10 ( subtract 2 from both sides )

6x = 8 ( divide both sides by 6 )

x = $\frac{8}{6}$ = $\frac{4}{3}$

substitute this value into the equation of the parabola for corresponding y- coordinate.

y = 3( $\frac{4}{3}$ )² + 2

= (3 × $\frac{16}{9}$ ) + 2

= $\frac{16}{3}$ + $\frac{8}{3}$

= $\frac{24}{3}$

= 8

the point on the parabola with tangent parallel to y = 10x - 2 is ( $\frac{4}{3}$ , 8 )
