Answer:
n = -1
n = 8
Step-by-step explanation:
3n^2=21n+24
0=-3n^2+21n+24
0=-3(n^2-7n-8)
0=-3(n+1)(n-8)
0=n+1
n=-1
0=n-8
n=8
Answer:
N = 8 n N = -1
just substitute the values of n in the equation

Step-by-step explanation:
To solve slope with points, use the equation: [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]. In this case it would be: [tex]\frac{7 - (-2) }{-6- (-7) }[/tex]. 7 - -2 is also 7 + 2 or 9. -6 - - 7 is also -6 + 7 or 1. So the final fraction is [tex]\frac{9}{1}[/tex] or 9.

Each serving for a box of trail mix is 3/8 of a cup.
Enter the number of 3/8 -cup servings there are in 1 1/2 cups of trail mix.
Answers
Answer:
It's 4
Step-by-step explanation:
It asks how many 3/8 cups are in 1 1/2 cups. So, we divide.
1 1/2 ÷ 3/8. We have to change the 1 1/2 into a improper fraction. 1 1/2 = 3/2. 3/2 ÷ 3/8 = 3/2 ÷ 8/3 = 24/6. Simplify, and you get 4. :)

Number 13 Find the measures of angles 1, 2, and 3.
Answers
Answer:
1. 37
2. 26
3. 26
Step-by-step explanation:
Subtracting 63 from 180, you find the linear pair, being 117 which helps find an angle in the lower triangle. The sum of all angles is 180, and to find 2, you subtract the known angles ( 180-(37+117)) which equals 26. Knowing the shape is a parallelogram, and the opposite sides are parallel, we can say 2 and 3 are congruent through the alternate interior angles theorem. 1 is found through applying the same theorem.

b.) 6m, 9m, 16m
c.) 16m, 24m, 38m
d.) 22m, 28m, 51m
Answers
Answer:
the largest angle=<PQR
c.) 16m, 24m, 38m
The largest angle of the triangle is ∠PQR and the measurements of the triangles are 16m, 24m, 38m
What is a Triangle?A triangle is a three-sided flat figure or polygon with three angles.
A triangle has three vertices, and the internal angles amount to 180°.
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x L x B
For a right angle triangle
From the Pythagoras Theorem ,
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the triangle be represented as ΔPQR
Now , the measure of side PQ = 7
The measure of side QR = 8
The measure of side PR = 14
Now , for a triangle , the angle opposite the smallest side of a triangle has the smallest measure.
And , the angle opposite the largest side has the largest measure
So , the angle opposite to the side PR = ∠PQR
Therefore , The triangle's largest angle is ∠PQR
Now , the measure of the sides of the triangles are given and
a + b > c
when a = 16 , b = 24 and c = 38
16 + 24 > 38
40 > 38
Therefore , the measures 16m, 24m, 38m form a triangle
Hence , the triangles are solved

For the first question the answer is 50(0.2 + 1)^2 = 72
For the second question it is y = 32
Step-by-step explanation:
In case you need to see how i got it...it's below
For number 1, y is proportional to (x + 1)^2
The equation would be y(x +1)^2 = k(the constant). Then I substituted numbers you gave me in the equation which was : 50(0.2 + 1)^2 = k(72)
For number 2 I used this equation: y (x + 1)^2 = 72. I substituted x for 0.5. The equation will be: y(0.5 + 1)^2 = 72. Then I got 32 for y.
Hope this helps:)

What conclusion can the mechanic make about the two kinds of motor oil?
A
The rate of temperature increase for the first motor oil is 0.5°F greater than that of the second motor oil.
B
The rate of temperature increase for the first motor oil is 3°F greater than that of the second motor oil.
C
The rate of temperature increase for the second motor oil is 3°F greater than that of the first motor oil.

Which variable should an expression be substitute for?
Answers
9514 1404 393
Answer:
x
Step-by-step explanation:
There is already an expression given for x, so that is the easiest variable to substitute for.
Substituting for x using the second equation, you have ...
-3(-2y+14) +y = -14
6y -42 +y = -14
7y = 28
y = 4
x = -2(4) +14 = 6
The solution is (x, y) = (6, 4).
_____
Substitution for x is the easiest.
__
The first equation could be rearranged to give an expression for y:
y = 3x -14
Then that can be used to substitute for y in the second equation. My lazy brain judges that to be more work.
