Answer:
x=15 y=3
Both (4x+10y) and (6x) equal 90 degrees, as angle 4x+10y is vertical to a 90 degree right angle, and angle 6x is directly beneath the right angle, making it equivalent. To find x, you simply do 90/6, which is 15, meaning x=15. Now plug in that into 4x+10y=90, which will make it 60+10y=90. Subtract 60 from 90, and divide the difference, 30, by 10, giving you 3, thus showing that y=3. You can double check by plugging in the x and y values.

Answer:
(5,1)
If you use substitution it'll be very easy.
In this case substitute the second equation into the first so you get y+4+y=6. Then simplify and you'll get 2y=2. Then solve for y and you'll get 1. Now plug in the 1 for y into either of the equations. Let's plug it into the second equation. X=1+4. X=5.
Final answer is (5,1).
The solution to the system of equations is x = 5, y = 1
The given system of equations is:
x + y = 6......(1)
x = y + 4......(2)
Substitute the equation x = y + 4 into the equation x + y = 6
y + 4 + y = 6
Collect like terms
y + y = 6 - 4
2y = 2
y = 2/2
y = 1
Substitute y = 1 into equation (2)
x = 1 + 4
x = 5
The solution to the system of equations is x = 5, y = 1

express the trinomial (3x+8)(x-2)
Answers
Answer:
3x² + 2x -16
Step-by-step explanation:
(3x+8)(x-2)
=> 3x(x) + 3x(-2) + 8(x) + 8(-2)
=> 3x² - 6x + 8x - 16
=> 3x² + 2x -16
The expanded form of the trinomial (3x+8)(x-2) is 3x² + 2x -16
To expand the trinomial (3x+8)(x-2), we can use the distributive property.
First, we multiply the first terms of each binomial: 3x * x = 3x^2.
Next, we multiply the outer terms: 3x * -2 = -6x.
Then, we multiply the inner terms: 8 * x = 8x.
Finally, we multiply the last terms of each binomial: 8 * -2 = -16.
Putting it all together, we have:
(3x+8)(x-2)
=> 3x(x) + 3x(-2) + 8(x) + 8(-2)
=> 3x² - 6x + 8x - 16
=> 3x² + 2x -16

classify ∠2 and ∠6. Compare angle measures, and give the postulate or theorem that justifies it.
Answers
Answer:
Explanation
Step-by-step explanation:
Angles 2 and 6 are corresponding angles in a transversal meaning they have the same measure.
The two straight lines are parallel and the co-position angles are equal, ∠2 =∠6
What is angle?
An angle is formed when two straight lines as well as rays meet at a single endpoint. The point where two points converge is known as an angle's vertex. The term "angle" comes from the Latin word "angulus," that also means "corner."
Parts of Angles:Vertex: A vertex is a corner of an angle or the intersection of two lines or sides.
Arms: The angle's two sides joined at a single end.
Initial Side: A straight line from which an angle is drawn is referred to as the reference line as well.
The side that the angle measurement is done up to is known as the terminal side.
Acute angles have a vertex angle that is less than 90 degrees.
Obtuse angles range from 90° to 180°.
At its vertex, a right angle has an exact measurement of 90°.
A straight angle is one that is 180° in length.
Reflex angles range from 180° to 360°.
A 360° angle is a full circle.
Solution:
The third straight line intersects the two parallel lines, creating angles 2 and 6.
∴ ∠2 and ∠6 are on the same side of the section line, and on the same side of the truncated parallel line.
∴ ∠2 and ∠6 are co-positions angles.
∴ ∠2 =∠6
Theorem :
The two straight lines are parallel and the co-position angles are equal.

Range: {-6, 1, 5, 6}
The domain of a relation is the x-values and the range is the y-values. In a coordinate pair the first digit is x and the second is y. So to find the domain put the first digits of each pair in order from least to greatest. Then to find the range do the same with the second digits in each pair. However, if a value repeats in the domain or range only put it once.

A solid with dimensions of 3.0 cm X 4.0 cm X 2.0 cm has a mass of 28 g. Will this solid float in

Answers
Answer:
no because the density is higher than water at 1.166667
Step-by-step explanation:
No, this solid doesn't float in water because the density is higher than water at 1.166667.
To find solid float in water or not.
What is density?Density is the measurement of how tightly a material is packed together.
It is given that :
dimensions of solid is 3.0 cm X 4.0 cm X 2.0 cm
The volume in milliliters is equal to the cubic centimeters.
So volume=3.0 cm X 4.0 cm X 2.0 cm
volume=24 [tex]cm^{3}[/tex]
Mass=28 g
Density= 1.00 g/ml
By the formula,
Density=Mass/ volume
1.00 g/ml=28 g/24 [tex]cm^{3}[/tex]
1.00 g/ml<1.166667
density of solid >density of water
So, the solid sink in water because the density is higher than density of water at 1.166667.
