Please help me

Answer 1

Answer:

Given:

The figure of a right angle triangle.

A line segment intersect the two sides and parallel to third side of the triangle

To find:

The value of x.

Solution:

According to basic proportionality theorem, if a line segment intersect the two sides and parallel to third side of the triangle, then it divides the two sides proportionally.

Using basic proportionality theorem, we get

$(8)/(20-8)=(6)/(x)$

$(8)/(12)=(6)/(x)$

$(2)/(3)=(6)/(x)$

On cross multiplication, we get

$2* x=6* 3$

$2x=18$

$x=(18)/(2)$

$x=9$

Therefore, the value of x is 9.

Solve the equation for y. 8x – 9y = 11a. .y=-9/8x-9/11
b. .y=9/8x 11/8
c. .y=-8x-11
d. .y=8/9x-11/9

Answers

8x - 9y = 11 (subtract 8x from each side)

- 9y = -8x + 11 (divide -9 from each side)

$(-9y)/(-9) = (-8x+11)/(-9)$

y = $(-8)/(-9) x - (11)/(9)$

D. $y=(8)/(9) x - (11)/(9)$

A set of equations is given below: Equation C: y = 5x + 10 Equation D: y = 5x + 2 Which of the following best describes the solution to the given set of equations? One solution No solution Two solutions Infinitely many solutions

Answers

The system of equations has no solution.

What is equation?

An equation is arrangement of variables and coefficient which provides to understand given statement in form of numbers .That means a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.

How to solve?

Given equation y=5x+10 and other equation y=5x+2

to check if two have any solution possible we will substitute value and check if RHS=LHS or not

∴y=5x+10=5x+2

=5x+10=5x+2

⇒0= -8

hence RHS≠ LHS hence no solution is possible

#SPJ2

The system of equations
$\left \{ {{y = 5x + 10 } \atop { y = 5x + 2}} \right.$

you can easily see that they are contrary to the equation . We not solve them . However prove it.

by substitution .
We substitute the value of y from the first equation to the second equation

y = 5x + 10
y = 5x + 2

y = 5x + 10
5x + 10 = 5x + 2

y = 5x + 10
5x - 5x = 2 - 10

y = 5x + 10
0 ≠ -8

or by opposing coefficients
y = 5x + 10 [* (-1)
y = 5x + 2

-y = -5x - 10
y = 5x + 2
----------------- sum
0 ≠ -8

Answer. No solution

Her results are shown in the table.How does the experimental probability of choosing a Queen compare with the theoretical probability of choosing a Queen?

The experimental probability is 4 less than the theoretical probability.
The experimental probability is 1/15 less than the theoretical probability.
The experimental probability is 1/15 more than the theoretical probability.

Answers

The experimental probability is 1/15 less than the theoretical probability.

Given

A set of face cards contains 4 Jacks, 4 Queens, and 4 Kings.

Carlie chooses a card from the set, records the type of card, and then replaces the card.

She repeats this procedure a total of 60 times. Her results are shown in the table.

What is experimental probability?

Theoretical probability describes how likely an event is to occur.

The theoretical probability of choosing a Queen is;

$\rm Theoretical\ probability= (Observed \ frequency)/(Probability \ of \ selecting \ Queen)\n\n Theoretical\ probability= (16)/(4)\n\n Theoretical\ probability= (4)/(1)$
