The solution of the system is

Answer:

3x+4y+7y = 3x + 11 y

Step-by-step explanation:

We need to simplify the given expression i.e.

3x+4y+7y

We know that, the like terms gets add up i.e. the sum of 4y and 7y equals 11 y

So,

3x+4y+7y = 3x + 11 y

Hence, the final simplification should be 3x + 11 y.

Answer: The equation in slope-intercept form: [tex]y=-5x+2[/tex]

Step-by-step explanation:

The given equation of a line : [tex]y+3= -5(x-1)[/tex]

The equation of a line in slope -intercept form: y=mx+c, where m= slope , c=y-intercept.

We first use distributive property(a(b+c)=ab+ac) to simplify the given equation, we get

[tex]y+3=-5x+5[/tex]

Subtract 3 from both sides, we get

[tex]y=-5x-2[/tex]

Hence, the equation in slope-intercept form: [tex]y=-5x+2[/tex]

Answer:

y = -28/5

Step-by-step explanation:

R = 7x +5y

35 = 7(9) + 5y

35 = 63 +5y

-5y= 63- 35

-5y/-5 = 28/-5

Y = -28/5

Answer:

Y = - [tex]\frac{28}{5}[/tex]

Step-by-step explanation:

Given

R = 7X + 5Y ← substitute X = 9, R = 35

35 = 7(9) + 5Y

35 = 63 + 5Y ( subtract 63 from both sides )

- 28 = 5Y ( divide both sides by 5 )

- [tex]\frac{28}{5}[/tex] = Y

All the correct congruence statements are,

⇒ ∠R = ∠C

⇒ AB = PQ

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

Triangles ABC and PQR are congruent.

Now, By definition of congruency we get;

All the correct congruence statements are,

⇒ ∠R = ∠C

⇒ AB = PQ

Thus, All the correct congruence statements are,

⇒ ∠R = ∠C

⇒ AB = PQ

Answer:

  an = 5 +3(n -1)

Step-by-step explanation:

The n-th term of an arithmetic sequence is ...

  an = a1 +d(n -1)

Here, you have first term a1=5 and common difference d=8-5=3, so the n-th term is ...

  an = 5 +3(n -1)

_____

If you like, you can simplify this to ...

  an = 5 +3n -3

  an = 3n +2

Answer:

g(x) = [tex]2^{x}[/tex] + 4

Step-by-step explanation:

Given f(x) then f(x) + c is a vertical translation of f(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Here the shift is 4 units up , then

g(x) = [tex]2^{x}[/tex] + 4

Answer:

the answer is B g(x)=2^x+4

Answer:

See explanation

Step-by-step explanation:

Recall that all the sides of the square are equal

Hence;

Area of a rectangle= l * b ------- equation 1

Perimeter of a rectangle = 2(l + b)----------equation 2

Area of the rectangle = 140 square centimeters

140 = lb

l = 140/b

Perimeter of the rectangle =  54 centimeters

substituting l = 140/b into equation 2

54 = 2(140/b + b)

Multiplying through by b

54b = 280 + 2b^2

Hence;

2b^2 - 54b + 280 = 0

Solving the quadratic equation

b=20 or b=7

substituting b=20 or b=7 into l = 140/b

l = 140/20 or l = 140/7

l = 7 or 20

THEREFORE;

b=20 cm or b=7 cm

l = 7cm or 20cm

Answer:

x=-5/11, y=-9/11. (-5/11, -9/11).

Step-by-step explanation:

3x+2y=-3

y=4x+1

---------------

3x+2(4x+1)=-3

3x+8x+2=-3

Answer:

The value of b is either + 6 or -6

Step-by-step explanation:

Here, given that we have the value for the discriminant, we want to calculate the value for the coefficient of x

mathematically, the discriminant can be calculated using the equation;

D = b^2 - 4ac

a represents the coefficient of x^2 which is 3

b represents the coefficient of x given as b

2 represents the last number

D is the discriminant = 12

So we have that;

12 = b^2 - 4(3)(2)

12 = b^2 - 24

b^2 = 24 + 12

b^2 = 36

b = √36

b = +6 or -6
