Answer:

(- 4, - 10 )

Step-by-step explanation:

y = 5x + 10 → (1)

y = 4x + 6 → (2)

Substitute y = 5x + 10 into (2)

5x + 10 = 4x + 6 ( subtract 4x from both sides )

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

x = - 4

Substitute x = - 4 into either of the 2 equations and evaluate for y

Substituting into (1)

y = 5(- 5) + 10 = - 20 + 10 = - 10

solution is (- 4, - 10 )

<h2>>> Answer </h2>

__________

\:

\sf{y = 5x + 10...(1)}

\sf{y = 4x + 6...(2)}

  • Subtitute (1) to (2)

\sf{y = 4x + 6}

\sf{5x + 10 = 4x + 6}

\sf5x - 4x = 6 - 10

\sf{x =  - 4}

.

  • Subtitute x = -4 to (1)

\sf{y = 5x + 10}

\sf{y = 5( - 4) + 10}

\sf{y =  - 20 + 10}

\sf{y =  - 10}

.

\longmapsto \sf{( - 4 , - 10)}

vladimir1956 [14]
Let the width be w

Width = w
Length = w + 6
Area = a

a = w(w + 6)
a = w² + 6w

In the accompanying diagram of right triangle ABC, the hypotenuse if AB, AC = 3, BC = 4, and AB = 5. Sin B is equal to
Trava [24]

Answer:sin(B)=\frac{3}{5}

Step-by-step explanation:

We are given that a triangle ABC is a Right Angled Triangle. The side AB is hypotenuse, so the angle opposite to side AB which will be angle C is a Right Angle (measures 90 degrees)

We have the side length of all 3 sides. Based on this information, we can construct a triangle with given measures. The triangle is shown in the attached image.

We have to find the value of Sin(B). Sin of an angle is defined as:

sin(\theta)=\frac{\text{Opposite Side}}{\text{Hypotenuse}}

The side opposite to angle B is AC with a length of 3 and hypotenuse is side AB with length 5. So Sin of angle B would be:

sin(B)=\frac{3}{5}

What is 25% of 24?<br> What is 15% of 60?<br> 9 is what percent of 72
JulsSmile [24]

Answer:

6

9

6.48

Step-by-step explanation:

this is the easiest way to solve for percentage:

\frac{part}{whole} =\frac{part}{whole}  Where all the percents (except 100) would go in part

and the whole number would go in whole

\frac{25}{100} =\frac{?}{24}  Then multiply 24 × 25 ÷ 100 = 6

\frac{15}{100} =\frac{?}{60}  Multiply 60 by 25 then divided by 100 = 9

Then for the last one 9 is what percent of 72

all we have to do is multiply 9 and then convert 72 into a decimal (0.72)

Then 9 × 0.72 = 6.48
