11 = 1 + 3r + 2r

I really need help with this!!

Answers

Answer 1

Answer:

r = 2

Step-by-step explanation:

I'm assuming we're finding r

11 = 1 + 3r + 2r

Add up the numbers with r

11 = 1 + 5r

Subtract both sides by 1

11 = 1 + 5r

-1  -1

10 = 5r

Divide both sides by the coefficient, 5, to isolate the variable, r

10/5 = 5r/5

r = 2

Answer 2

Step-by-step explanation:

11=1+5r

11-1=5r

5r=10

r=10/5

r=2

Tina chose A as the correct answer. How did she get that answer?

Answers

Answer: Tina is correct

Step-by-step explanation:

this is because in one foot there are 12 inches and there are 5 feet so 5 X 12= 60 and aaron is 63inches so he is tall enough and 63-60=3 inches so he is 3 inches taller than 5 feet.

Pls give me brainliest!!!

Answer:

Yes. He is 3 inches taller than 5 feet

Step-by-step explanation:

We know that 1 ft is 12 inches

5 ft  * 12 inches/ 1 ft = 60 inches

You must be 60 inches to ride and Aaron is 63 inches

He is 3 inches taller

63 - 60 = 3 inches

Find the coordinates of the intersection of the diagonals of parallelogram GHJK with vertices G(−4, 5), H(3, 5), J(2, −1), and K(−5, −1).

Answers

Answer:  1,2.4

i'm not sure thoo

Step-by-step explanation: :3

The coordinates of the intersections of the diagonal of parallelogram GHJK will be ( -1, 2 ).

What is parallelogram?

A parallelogram is a quadrilateral having four sides and the two opposite sides are equal and parallel to each other.

Given that:-

The coordinates the intersection of the diagonals of parallelogram GHJK with vertices G(−4, 5), H(3, 5), J(2, −1), and K(−5, −1).

The intersection point will be the midpoint between the points G and J or points K and H.

The coordinates of the points H and K are ( 3,5)  and K ( -5,-1). So the midpoint will be calculated as:-

Midpoint = [tex]\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}[/tex]

Midpoint = [tex]\dfrac{-5+3}{2},\dfrac{5-1}{2}[/tex]

Midpoint = [tex]-\dfrac{2}{2},\dfrac{4}{2}[/tex]

Midpoint = (-1,2)

Therefore the coordinates of the intersections of the diagonal of parallelogram GHJK will be ( -1, 2 ).

The equation of the line of best fit relating age (in years, x) and the median height (in cm, y) of boys is given.

y = 6.5x + 75.5y=6.5x+75.5
Predict the median height of boys age 13.

help plss

Answers

Answer:

160 cm

Step-by-step explanation:

y=6.5(13)+75.5

y=160 cm

Or about 5.2ft

If the equation of the line of best fit is y = 6.5x + 75.5, the predicted median height of boys at age 13 is 160 cm.

To predict the median height of boys age 13, we can use the equation of the line of best fit relating age (x) and median height (y) for boys, which is given as:

y = 6.5x + 75.5

To find the predicted median height at age 13, we substitute x = 13 into the equation and solve for y.

Plugging in x = 13, we have:

y = 6.5(13) + 75.5

Calculating the expression, we get:

y = 84.5 + 75.5

Simplifying further, we have:

y = 160

Using the equation of the line of best fit, we can estimate the relationship between age and median height for boys. In this case, plugging in x = 13 into the equation, we find that the predicted median height at age 13 is 160 cm.

Answer:

f(x)5.79(3)^2 for task 1

Step-by-step explanation:

Answer:

Step-by-step explanation:

Task 1:

Non linear systems of equations:

x + y = 1 -------------------(I)     {Linear equation}

     y =  1 - x

y = x² - 5 ---------------(II)   {Quadratic equation}

Substitute y =1 - x in equation (II)

(II) -->   1 -x = x² -5

Add 'x' to both sides

1 = x² + x - 5

0 = x² + x - 5 - 1   {Subtract 1 from both sides}

x² + x - 6 = 0

x² + 3x - 2x - 6 = 0    {Rewrite the middle term}

x( x + 3) - 2(x + 3) = 0    

(x + 3)(x - 2) = 0

x + 3 = 0       ;  x - 2 = 0

x = - 3   ; x = 2

When x =  - 3 ,   y = 1 -(-3 )

                              = 1 + 3

                             y = 4

When x = 2  ; y = 1 - 2 = -1

Solution of the equations:  (-3,4)  & ( 2,-1)

Task 2:

Part 1: x = 40   ; y = 30

(x - y)² = x² - 2xy + y²

(40 - 30)² = 40² - 2*40*30 + 30²

               = 1600 - 2400 + 900

               = 2500 - 2400

                = 100

Part 2:

a = 10 , b = 11

a³ + b³ = (a + b)(a² - ab +b²)

(10)³ + (11)³ = (10 +11)(10² -10*11 + 11² )

              = 21* (100 - 110 + 121)

              = 21 * ( 221 - 110)

              = 21 * 111

              = 2331
