What is the solution to the system of equations?

2x+y=11
1/2x-5y=8

please help!!!

Answers

Answer 1

Answer: ( x,y ) = ( 96/43, 152/43 )

Step-by-step explanation:

Answer: ( x,y ) = ( 96/43, 152/43 )

Step-by-step explanation:

rewrite the expression

2x + y=8

11 1/2 x X - 5y=8

mixed fraction btw.

simplify

2x + y =8

23x - 10y = 16

multiply both sides

20x + 10y = 80

23x - 10y = 16

eliminate one variable by adding the equations

43x =96

divide both sides

x = 96/43

substitute the value of x

2 x 96/43 + y = 8

solve the equation

y = 152/43

a possible solution is

( x,y ) = ( 96/43, 152/43 )

check solution

simplify

8 = 8 = 8

the ordered paired is a solution!

final answer: ( x,y ) = ( 96/43, 152/43 )

Answer 2
rewrite the first equation as y = -2x+11
plug in this equation into the second equation
solve for x
x=6

plug x=6 into the first equation
solve for y
y=-1

THE ANSWER IS (6,-1)

you can also graph the two equations on desmos and the point where the two lines intersect is the answer

Find the area of a triangle with a base length of 3 units and a height of 4 units.

Group of answer choices

3 units

7 units

Answers

Answer:

[tex]6[/tex] square units

Step-by-step explanation:

The area of a triangle can be calculated by multiplying the triangle's base by its height, and then dividing the result by [tex]2[/tex]. As an algebraic expression, this would be [tex]\frac{bh}{2}[/tex], where [tex]b[/tex] is the triangle's base and [tex]h[/tex] is the triangle's height. In this case, we know that [tex]b=3[/tex] and [tex]h=4[/tex]. Therefore, the area of this triangle is [tex]\frac{3*4}{2} =\frac{12}{2} =6[/tex] square units. Hope this helps!

the area is 6 units.

the area of the parallelogram shown is 9 square inches set up and solve an equation to find the value of

Answers

ANSWER: X = 45
First, you have to set up the equation.
If the area of the square is 9, and one side is 3 square units, then the other side must also be 3 units because 3X3=9.
When finding the value of a variable, you ALWAYS want to get the variable alone on one side.
So now, you take the equation, 1/9x-2 and make is equivalent to 3.
1/9x-2=3
Now, to simplify, you add to to undo the -2, and add 2 to the 3
1/9x-2(+2)=3+2
So now the equation is 1/9x=5
To undo a fraction, think of it as a division problem. To undo a division problem, you must multiply the fraction by the denominator.
1/9x(9)=5(9)
5X9 is 45
So the answer is X=45
And is you want to check it:
1/9(45)-2=3
1/9X45 is 45/9 or 5
5-2=3
3=3
The answer is X=45

If the area of the parallelogram shown is 9 square inches. The value of x will be 45.

What is parallelogram?

In two-dimensional geometry, it is a plane shape having four sides, in which two pairs of sides are parallel to each other and equal in length. The sum of all angles in a parallelogram is 360°. Similar to how the area of a rectangle is calculated, the formula for calculating the area of a parallelogram is base times height.

It is given that the sides of the parallelogram are (1/9x-2) and 3 and the area is 9 square inches.

The area of the parallelogram will be the product of their sides as,

Area = Side A × Side B

A =  (1/9x-2) 3

9 = 1/3x-6

Simplify the equation to find the value of x,

9+6 = 1/3x

15=1/3x

x=45

Thus, if the area of the parallelogram shown is 9 square inches. The value of x will be 45.

Examine the linear graph. Determine the y-intercept and write the y-intercept in coordinate form. Then write the equation of the line in slope-intercept form.

Answers

Answer:

y-intercept: 100 (0, 100)

[tex]y=\frac{8}{7}x+100[/tex]

Step-by-step explanation:

The y-intercept is the point on a graph that crosses the y-axis, this line crosses the y-axis at 100.

slope-intercept form is: [tex]y=mx+b[/tex]

[tex]m=slope[/tex]

[tex]b=y-intercept[/tex]

This line has a slope of 8/7 and the y-intercept is 100 so the equation would be: [tex]y=\frac{8}{7}x+100[/tex]

y=8/3x+100 is the equation of the line in slope-intercept form.

What is Slope of Line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

From the given graph let us consider two points through which the line is passing.

(0, 100) and (42, 148)

Slope=148-100/42

=48/42=8/3

Now let us find the y intercept

100=8/3(0)+b

b=100

So slope intercept form is y=8/3x+100

Hence, y=8/3x+100 is the equation of the line in slope-intercept form.
