Answer: Grace is correct because a rhombus does not have right angles
Step-by-step explanation:
Grace's assertion is on point. Right angles are not present in all quadrilaterals.
What is quadrilateral?A quadrilateral in geometry is a four-sided polygon with four edges and four corners.
As per the definition of Quadrilateral and rectangle, the rectangle is the type of quadrilateral that has 4 right angles.
Other varieties of quadrilaterals consist of:
Trapezium: Doesn't must have four right angles, but has one pair of opposite sides that are parallel.
A parallelogram has four right angles, but not necessarily two sets of opposite sides that are parallel.
All four sides of a rhombus are equal in length, although there aren't always four right angles.
Kite: Does not must have four right angles, but two adjacent pairs of sides that are equal in length.
Therefore, Grace's assertion is right.

How do we write 8x-2y=10 in slope intercept form?
[tex]\blue\textsf{\textbf{\underline{\underline{Answer and Solution:-}}}}[/tex]
First subtract 8x on both sides:-
-2y=10-8x
or
-2y=-8x+10
Now divide by -2 on both sides:-
y=2x-5
This is our equation in slope intercept form.
Good luck.

Work out the surface area of this solid prism.
Find the value of x if the area of the trapezoid is 54.
Answer:
11
Step-by-step explanation:
area = (side a + side b)/2 times height
side a = (2 times (area ÷ height)) - side b
side a = (2 times (54+6)) - 7
side a = (2 times (9)) - 7
side a = 18 - 7
side a = 11

Solve the simultaneous equations
4x + 3y = 21
and
4x + 2y = 16
Answer:
x= 1.5
y=5
Step-by-step explanation:
do equation 1 and 2 then,
subtract the equation
find the value of y by subtracting
and put the value of y in any equation and get the value of x
Step-by-step explanation:
4x+3y=21
4x+2y=16
If we add both the equation:
4x + 3y = 21
4x + 2y = 16
(-) (-) (-)
4x + 3y = 21
-4x - 2y= -16
=> 0+1y= 5
y=5
substituting Y in eq 1
4x+3y=21
4x+3(5)=21
4x+15=21
4x=21-15
4x=6
x=1.5
x=1.5 and y=5MARK ME AS BRAINLISTPlease i really need help, i really need this i will give a brainliest to the people that answer correctly
Answer:
Step-by-step explanation:
so to go forward we input x and get out y, to go backwards ( the inverse) we plug in y and get out x , so just solve the equation for x
f(x) = 8x - 5
remember that f(x) = y
so,
y = 8x - 5
now solve for x
y+5 = 8x
(y+5) / 8 = x
then remember that we want to swap x and y ,
(x+5) / 8 = y
now y = [tex]f^{-1}[/tex](x), it's kinda confusing.
[tex]f^{-1}[/tex](x)= [tex]\frac{x+5}{8}[/tex]

Evaluate 1/4r+7/24 when r=1/6
Step-by-step explanation:
If r is 1/6 then we'll have 1/4*1/6+7/24.
Firstly we will multiply 1/4 and 1/6 which will give us 1/24.
Then we will add 1/24 and 7/24 which will give us 8/24.
Then we reduce it to it's lowest term that is 1/3.TRY THIS.

What are the solutions to the system of equations? y=x2−7x+12y=−x+7
Answer:
x = 1, y = 6
or
x = 5, y = 2.
Step-by-step explanation:
y=x2−7x+12
y=−x+7
Substitute for y in the first equation:
- x + 7 = x^2 - 7x + 12
x^2 - 7x + x + 12 - 7 = 0
x^2 - 6x + 5 = 0
(x - 1)(x - 5) = 0
x = 1, 5.
When x = 1, y = -1 + 7 = 6.
when x = 5, y = -5+7 = 2.

Answer:
[tex]\frac{10x^2+3}{y^2+4}[/tex]
Step-by-step explanation:
When adding rational numbers, if the denominator is the same you simply keep the denominator (bottom of fraction) as it is and apply the operation given to the numerator ( top of fraction )
So we have [tex]\frac{6x^2+5}{y^2+4} +\frac{4x^2-2}{y^2+4} =\frac{(6x^2+5)+(4x^2-2)}{y^2+4}[/tex]
==> remove parenthesis and apply signs
[tex]\frac{x^2+5+4x^2-2}{y^2+4}[/tex]
==> simplify numerator by combining like terms
[tex]\frac{10x^2+3}{y^2+4}[/tex]
and we are done!
Note:
like terms are terms with the same variable and exponent
An example of like terms are 6x^7 and 3x^7 as they have x as a variable and a power of 7
The like terms being combined here were (6x² and 4x²) and (5 and -2)

combone the like terms

7. The cost, c(x), for a carriage ride is given by c(x) = 2x + 4, where “x” is the number of minutes. Graph c(x), including the correct axis labels.
As m is a constant that is applied to x, it has to have something to do with minutes, eliminating A and B. As the constant is 2, it has to have something to with 2, eliminating D, meaning your answer is C. This is because a slope is the rate of change of y in relation to x, so it would be rate of change of y is a (a being your constant, in this case 2) per x. With your case, y is cost and x is minutes, leading to answer choice C.
