Answer:
Observation : No two such factors can be found !! Conclusion : Trinomial can not be factored. Equation at the end of step 2 : 2n2 - 7n - 5 = 0. Step 3 : Parabola ...
Step-by-step explanation:
Tell whether the angle measures can be those of a triangle.
20°, 160°, 20°
Yes, can be those of a triangle.
No, cannot be those of a triangle.
No.
The 3 angles of a triangle need to equal 180 degrees.
The sum of the 3 given angles is greater than 180 ( 160 + 20 + 20 = 200) so it cannot form a triangle.
What is the slope of the line passing through the points (-9,-3) and (7,-7)
Answer:
The slope is [tex]\frac{1}{4}[/tex]
Step-by-step explanation:
[tex]\frac{Y_{2} -Y_{1} }{X_{2}-X_{1} }[/tex]
-7-(-3)= -7+3= 4
4/?
7-(-9)= 7+9 = 16

Describe how to find the sale price of an item that has been discounted 15%.
Multiply the original price by
% to find the sale price.
Multiply the discount percent to the marked price and subtract from the marked price.
What will be the selling price?As we know that the discount is always given on the marked price of the product.
We will take one example to understand it supposes the marked price of any object is MP= 100 and the discount =15% so to find the SP
First, find the discount amount
[tex]MP\times Discout \ percent =100\times \dfrac{15}{100} =15[/tex]
Now to find the SP subtract the discount from the MP
[tex]SP=MP-Discount[/tex]
[tex]SP=100-15=75[/tex]
So for finding SP multiply the discount percent to the marked price and subtract from the marked price.

If you add Natalie's age and Fred's age, the result is 42. If you add Fred's age to 3 times
Natalie's age, the result is 70. Write and solve a system of equations to find how old Fred and
Natalie are.
Answer:
N+F=42 & F+3N=70 System Solved: Natalie is 14 and Fred is 28
Step-by-step explanation:
Using variables N=natalies age and F=Freds age
N+F=42 ----> N=42-F (take this and plug it into the other equation)
F+3N=70 so F+3(42-F)=70 [simplify] F+126-3F=70 [further simplify]
-2F=-56 [divide -56 by -2] F=28 [then plug this number into the orig. equation]
So N+28=42 or N=14.

Answer:
4x + 12x = 320
16x = 320
x = 20
Step-by-step explanation:
This is because the diagram shows 4x + 12x and the total being, 320.
4x + 12x = 16x
and 320/16 = 20
so x = 20

John buys 6 shirts. For every shirt you purchase, you get one for 30% off. If the normal
price for each shirt is $20.00, how much money did John spend on his shopping trip? (Tax is not being calculated.)
Answer:
$36
Step-by-step explanation:
Basically, every shirt is $6 because 30% of 20 is 6. If he buys 6 shirts, then 6 times 6 is 36 dollars spent, tax not included.

Answer:14 is obtuse
15 is A
Step-by-step explanation:
For 14 the only remaining angle is over 90
For 15 the first triangle has all same side and angle measures
second triangle has 2 equal side measures
and third has none
Answer:
1: Obtuse
2: A
Step-by-step explanation:
One angle is 57° and another is 12°. If we add them, we get 69. Subtract 69 from 180 to get missing angle: 180-69=111
the missing angle is 111°. We know this is not a right triangle because those have a 90° angle. Since one angle is bigger than 90 (111°), the triangle is obtuse.
For the second one, we see that the first triangle is equal on all sides, so it is equilateral. The second triangle has just two equal sides, so it is isosceles. The thrid one is different side length on all of them, so it is scalene. the answer is A.

Out of 12 students, 3 liked Hamlet 3/12 is 1/4 simio lidies and 1/4 can be 25%
Answer:
1/4 would be the answer
Step-by-step explanation:
There are 12 total students in the class, and 3 of them liked Hamlet best. So the chances of randomly picking a Shakespeare student that likes Hamlet best is 3/12. If we simplify this answer, we would get 1/4.
During his shift at Pennant Sports Shop, Sam compared the items sold during last weekend's sale. There were 25 lacrosse sticks sold on Friday, 10 of which were defense sticks. There were 50 lacrosse sticks sold on Saturday, 15 of which were defense sticks. Did Pennant Sports Shop sell the same ratio of defense sticks to total lacrosse sticks on both days?
Answer: No. Pennant Sports Shop did not sell the same ratio of defense sticks to total lacrosse sticks on both days.
Step-by-step explanation:
On Friday, there were 25 lacrosse sticks sold, 10 of which were defense sticks. The ratio of defense sticks to lacrosse will be:
= 10/25 = 2/5 = 2:5
On Saturday, there were 50 lacrosse sticks sold, 15 of which were defense stick. The ratio of defense sticks to lacrosse will be:
= 15/50 = 3/10 = 3:10
Based on the calculation above, Pennant Sports Shop did not sell the same ratio of defense sticks to total lacrosse sticks on both days

Answer:
C) Line A does not intersect Line B.
Step-by-step explanation:
Line A passes through (6 ,-30) & (-2 , 10)
Line B passes through (-4 , 28) & (2 , -2)
Find the slopes for each line. To find the slope, use the slope formula:
slope (m) = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
Line 1:
Let:
[tex](x_1 , y_1) = (6 , -30) \\(x_2 , y_2) = (-2 , 10)[/tex]
Plug in the corresponding numbers to the corresponding variables:
m = [tex]\frac{10 - (-30)}{-2 - 6} = \frac{10 + 30}{-8} = \frac{40}{-8} = \frac{-5}{1}[/tex]
Line 2:
Let:
[tex](x_1 , y_1) = (2 , -2)\\(x_2 , y_2) = (-4 , 28)[/tex]
Plug in the corresponding numbers to the corresponding variables:
m = [tex]\frac{28 - (-2)}{-4 - (2)} = \frac{28 + 2}{-4 - 2} = \frac{30}{-6} = \frac{-5}{1}[/tex]
The two lines share the same slope, therefore, they are parallel to each other. This means that they do not intersect at any given point.

Function notation ? G (x)=x-3 ; find g(-6) .. how do I answer this?
Answer:
The value of g(-6) will be "-9".
Step-by-step explanation:
The given function is:
⇒ [tex]g(x)=x-3[/tex]
then,
⇒ [tex]g(-f)=?[/tex]
On putting the value "-6" at the place of "x", then we get
⇒ [tex]g(-6) = (-6)-3[/tex]
⇒ [tex]=-6-3[/tex]
⇒ [tex]=-9[/tex]
Thus the above is the correct solution.

cos 60º =
BIV x
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete as the image that illustrates the scenario is not given.
However, I can deduce that the question is about a right-angled triangle.
So, I will give a general explanation on how to find each of the side of the triangle, given a side and an angle.
For triangle A (solve for b)
Using cosine formula.
[tex]\cos \theta = \frac{Adjacent}{Hypotenuse}[/tex]
[tex]\cos 60= \frac{5}{b}[/tex]
Make b the subject
[tex]b= \frac{5}{\cos 60}[/tex]
For triangle B (solve for b)
Using cosine formula.
[tex]\sin \theta = \frac{Opposite}{Hypotenuse}[/tex]
[tex]\sin 60= \frac{b}{5}[/tex]
Make b the subject
[tex]b = 5\sin 60[/tex]
For triangle C (solve for b)
Using cosine formula.
[tex]\tan \theta = \frac{Opposite}{Adjacent}[/tex]
[tex]\tan 60= \frac{b}{5}[/tex]
Make b the subject
[tex]b = 5\tan 60[/tex]

Answer:
7.5 in.
Step-by-step explanation:
Answer:
7.5 in
Step-by-step explanation:
using pythagorean theorem
Hyp²= Opp² + Adj ²
where 9= hyp
5= adj
and x = opp
9²=x²+5²
81=x² + 25
collect like terms
81-25=X²
56=X²
since we're looking for X and not X²
we square root both sides
√x²=√56
x=7.483 approximately 7.5
