Quadratic binomial
Linear binomial
PLS HELP
Answer:
Quadratic trinomial
Step-by-step explanation:
(8x^2 + 3x) - (12x^2 - 1)
= 8x^2 + 3x - 12x^2 + 1
= 8x^2 - 12x^2 + 3x + 1

Answer:
The equation y = x/3 describes the relationship.
Step-by-step explanation:
Let's take two points. (0,0) and (3,1)
slope(m) = ((1-0)/(3-0)
= 1/3
now
y=mx+b
or, 1 =1/3 × 3 + b
or, 1 = 1+b
so, b = 0
now
y = mx+b
or, y = 1/3 × x +0
or, y = x/3
A tennis ball machine can launch 60 tennis balls in 12 minutes.
At this rate, how many tennis balls can it launch in an hour?
It's 300 because you divide 60 by 12 which gives you 5, then multiply 60 and 5.
Steps on how to solve a Surd
Answer:
There are two simple steps to surd simplification.
STEP - 1: Split the number within the root into its prime factors. √50=√(5×5×2)
STEP-II: Based on the root write the prime factors, outside the root. In case of square root, write one factor outside the root, for every two similar factors within the root. ...

The triangle shown below has an area of 32 units^2
2
squared.
Find the missing side.
=x, equals
units
Answer: Varies, missing side lengths could be 1, 2, 4, 8, 16, 32, 64, choose the one that works BEST for answering your problem, as there was no image
Step-by-step explanation:
for the triangle to have an area of 32, the "square" that it would make when multiplying the area by 2 would be 64...
so factors of 64 are 1, 2, 4, 8, 16, 32, and 64.
1 and 64 don't seem like good dimensions for the triangle, but could work
2 and 32 is another possibility
4 and 16 can work too
8 and 8 also is possible...
so pluging the lengths into the formula for a triangle...
(b* h)/2 should get you to 32.
Write an equation in slope-intercept form of the line that passes through (−2, 5) and (−4, −5).
Answer:
y = 5x + 15
Step-by-step explanation:
Slope m = (y2-y1)/(x2-x1)
m = (-5 - 5)/(-4 - -2) = -10/-2 = 5
y = 5x + b
Using (-2,5) then
5 = 5(-2) + b
5 = -10 + b
b = 15
then y = 5x + 15
Write an equation of the line (2,-1) and parallel to the line y=-3x+8
An equation of the parallel line is y= ?
Answer:
[tex]y=-3x+5[/tex]
Step-by-step explanation:
A line being parallel to another means it has the same slope, so the slope of the new line is also -3.
Slope-intercept form is:
[tex]y=mx+b[/tex]
where m is the slope, b is the y-intercept, and (x, y) is any point on the line. There are 4 variables in this equation, and we're already given 3 of them (slope, x, and y), so we can solve for the 1 unknown variable (y-intercept).
Plug in all known values:
[tex]\rightarrow y=mx+b\\\rightarrow(-1)=(-3)(2)+b[/tex]
Now, you can solve for b.
[tex]\rightarrow-1=(-3\times2)+b\\\rightarrow-1=-6+b\\\rightarrow5=b\\\rightarrow b = 5[/tex]
Finally, with both the slope and y-intercept, you can write the equation of the line:
[tex]y=-3x+5[/tex]

It took Daniela 3/4 of an hour to do her mouth and work it took her 4/5 of an hour to do the English homework how much more time do Daniela spend on her English homework then on her math homework
Answer:
Daniela spent 1/20 of an hour longer on her English homework than her Math homework.
Step-by-step explanation:
I think what your asking is how much longer Daniela took on her English homework then her math homework. If that's what your asking, you need to subtract 3/4 from 4/5.
First, the denominators need to be the same (meaning we have to multiply them):
4/5 * 4 = 16/20
3/4 * 5 = 15/20
Finally, we subtract the two fractions:
16/20 - 15/20 = 1/20
Question no. viii). In the given figure, O is centre of the circle. Find the value of x and y?
This is my last question.
Answer:
•x = 45° and
•y = 45°
Step-by-step explanation:
Given,
O is the centre of the circle
Let P be the exterior point
PA is the tangent
The angle between the radius of the circle and the tangent at the point of contact is 90°
angle BAP = 90°
So, ∆ BAP is a right angled triangle
Given that
BA and AP are equal
⇛angle APB = angle ABP
Since the angles opposite to equal sides are equal.
x = y
We know that
The sum of all angles in a triangle is 180°
⇛∠BAP+∠APB+∠ABP
Substitute the value in equation then, we get
⇛90°+x+y = 180°
⇛90°+x+x = 180°
⇛90°+2x = 180°
⇛2x = 180°-90°
⇛2x = 90°
⇛x = 90°/2
⇛x = 45°
⇛y = 45°
.°. x = y = 45°
Answer: Hence, the value of x = 45° and y = 45°.
Note: The angle between the radius of the circle and the tangent at the point of contact is 90°.

Answer:
The approx. length of a reptile that has a mass of 20.5 grams is 75
Step-by-step explanation:
y=0.3x-2
Okay so the value for y in the equation would be 20.5 so plug the value of y into the equation:
20.5 = 0.3x-2
And we are wanting to find the approximate length of a reptile that has a mass of 20.5 grams.
1. 20.5=0.3x-2
2. [tex]20.5=\frac{3x}{10} -2[/tex]

Which of the following are true about x? Check all that apply. X ∉ A x ∈ B x ∉ C x ∈ A ⋃ B x ∈ A ⋃ C x ∈ A ⋂ B.
You can use those given Venn diagram to deduce where does x lies.
The options that are true are:
Option B: x ∈ B
Option C: x ∉ C
Option D: x ∈ A ⋃ B
Option E: x ∈ A ⋃ C
Option F: x ∈ A ⋂ B
When do we say that x belongs to some set S?If x resides inside the set S, then we say that x belongs to set S and we write this fact symbolically as:
[tex]x \in S[/tex]
If x doesn't belong inside the set S, then we write it as:
[tex]x \notin S[/tex]
Example, if S = {1,2,3}, then let x = 3, then we say that 3 ∈ S
What are union and intersection of two sets A and B?For given Venn diagram, we can see that x lies inside A and B and the area where both A and B lies (A intersection B, written as A ⋂ B)(intersection of A and B is common area of both A and B).
Union of A and B is the whole area where A and B lies. It is denoted by
A ⋃ B
Since in this whole area, x is present, thus we say x ∈ A ⋃ B
Since x lies in the union of A and C too( the area where A and B wholly lie), thus we write x ∈ A ⋃ C
Thus, we have:
[tex]x \in A\\ x \in B\\ x \in A \cap B\\ x \in A \cup B\\ x \in A \cup C[/tex]
since x doesn't belongs to C, thus we can write [tex]x \notin C[/tex]
Thus, these options are correct:
Option B: x ∈ B
Option C: x ∉ C
Option D: x ∈ A ⋃ B
Option E: x ∈ A ⋃ C
Option F: x ∈ A ⋂ B

Which of the following is true for a circle with a circumference of approximately 100 feet:
A The radius is 16 feet and the area is 804 feet. B The diameter is 16 feet and the area is 804 feet.
C The radius is 16 feet and the area is 804 square feet.
D The diameter is 16 feet and the area is 804 square feet.
Answer:
C. The radius is 16 feet and the area is 804 square feet
Step-by-step explanation:
In A, it doesn't use the correct unit because it is supposed to say 804 feet square. In B, the diameter would be 50 I think, and again it doesn't say feet square for area. In C, the radius is 16 feet and the area is 804 square feet, so that is correct. In D, it says the diameter is 16 feet, but it had the correct area.

I keep putting in 24 minutes but it says I’m wrong? Someone help please!
Answer:
you are right
it is 24
Step-by-step explanation:
100% = 60
divide by 10 to get 10%
10%=6
x by 4 to get 40%
40%= 24
Answer:
40% of 60 minutes is x
is/of = %/100
x/60 = 40/100
100 * x = 60 * 40
100x = 2400
x = 2400/100
x = 24
So, 40% of one hour is 24 minutes.
40% of 1 hour is x
is/of = %/100
x/1 = 40/100
100*x = 40*1
100x = 40
x = 40/100
x = 0.4 hour... maybe they want you to write the answer in hours? So 0.4 hour instead of 24 minutes? Not sure.
