−4m2 + 2m + 5
A. The constant is 5.
B. There are three terms.
C. The variable in the first term is m.
D. The coefficient in the second term is 2m.
Answer:
D
Step-by-step explanation:
A coefficient is the number before a variable. The D statement isn't true because the coefficient would be 2 instead of 2m. 2m would be the whole term.
Answer:
D
Step-by-step explanation:
The coefficient is the number in front of the variable. the number in front of the second variable is 2, not 2m

Equation
(3x - 1) * 3 = 12*(x -2) Remove the brackets.
Solution
9x - 3 = 12x - 24 Add 24 to both sides.
9x - 3 + 24 = 12x - 24 + 24 Combine
9x + 21 = 12x Subtract 9x from both sides
9x - 9x +21 = 12x - 9x

56+(-56)
-240+370
-5.7+(-4.2)
Answer:
Step-by-step explanation:
well thie first one is 0 because the negative multiply by the posivive is negtive that will brake the parentisis 56-56 and that gives 0
the second one is 130 and it isnt negetive because the 370 us bigger than -240
the second one is -9,9 same one as the last ones
Answer:
0, 130, and -9.9
Step-by-step explanation:
56 + (-56) aka 56 - 56 = 0
-240 + 370 = 130
-5.7 + (-4.2) aka -5.7 - 4.2 = -9.9

Two families went to the movies. The Davis family paid $39 for 2 adult
tickets and 3 student tickets. At the same theater, the Tyler family paid $23
for 1 adult ticket and 2 student tickets. What is the price of a student
ticket?
Answer:
$7
Step-by-step explanation:
Let a be the price of the adult ticket and s be the price of the student ticket
That means that:
2a+3s=39
and
a+2s=23
Using elimination
-2(a+2s=23)
-2a-4s=-46
-2a-4s=-46
2a+3s=39
Eliminate a:
-s = -7 ; s = 7

How do you know
the quotient of 639 /
6 is greater than
100 before you actually divide
Answer:
because since the question is 639 / 6
we immediately know that 600 / 6 is 100
639 / 6 = 106.5
Answer:
You just need a little conversion to get the answer.
[tex]\frac{639}{6}=\frac{600}{6}+\frac{39}{6}\\ = 100+\frac{39}{6} >100[/tex]

a polynomial function with rational coefficients has the given roots. find two additional roots -2i and square root of 10
Answer:
(-2)(100) or 10^2 is 100
Step-by-step explanation:
(x -2)(x+100) =x
Additional roots of polynomial function P(x) with rational coefficients are (2i) and (- √10).
What is conjugate of complex number?
" If z = a +bi be the given complex number, then its conjugate is represented by [tex]\bar{z}[/tex] = a -bi , where real parts remain same only imaginary part get changed with opposite sign."
Theorem used
Conjugate Root theorem
Complex conjugate root theorem states that if P(x) is a polynomial in one variable with real coefficient , for P(x) if one root is a + bi with real numbers a and b then its conjugate that is a - bi is also another additional root of P(x).
According to the question,
Two given roots of polynomial function with rational coefficients are -2i and √10.
As per Conjugate root theorem,
Here one root is 0 - 2i then other root is its conjugate 0 + 2i
Also one root is 0 + √10 then another root is 0 - √10.
Therefore, two additional roots are 2i and -√10.
Hence, additional roots of polynomial function P(x) with rational coefficients are (2i) and (- √10).

Please help, please please
Answer:
y=90
x= 53
Step-by-step explanation:
Angles x,y and 37, when added together must equal 180. Because they create a straight angle.
the square u see on angle y, indicates its a right angle. Therfore 90.
so 90+37= 127 degrees.
and now we have to find what angle x is, which will make the degree 180.
so u do 180-127= 53 degrees
Answer:
Step-by-step explanation:
x+37=90
x=53
y=90+53
y=143
CAN SOMEONE PLEASE HELP THIS IS DUE AT MIDNIGHT (I’ll give brainlist)
Answer:
d° = 62°
e° = 90°
f° = 27°
g° = 27°
h° = 118°
j° = 62°
k° = 63°
Step-by-step explanation:
The relationship between the given angles are;
k° = 63° (Vertically opposite angles)
63° + f° = 90° (Given complementary angles)
∴ f° = 90° - 63° = 27°
f° = 27°
g° = f° (Vertically opposite angles)
∴ g° = f° = 27°
g° = 27°
e° + 63° + f° = 180° (The sum of angles on a straight equals 180°)
∴ e° = 180° - (63° + r°) = 180° - (63° + 27°) = 90°
e° = 90°
h° = 118° (Vertically opposite angles)
118° + d° = 180° (The sum of angles on a straight equals 180°)
∴ d° = 180° - 118° = 62°
d° = 62°
j° = d° (Vertically opposite angles)
∴ j° = d° = 62°
j° = 62°

Answer:
d = 9
Step-by-step explanation:
Given
1 = [tex]\frac{1}{3}[/tex] d - 2 ( multiply through by 3 to clear the fraction )
3 = d - 6 ( add 6 to both sides )
9 = d
Answer:
d=9
Step-by-step explanation:
First we can do same to both side by adding 2 to both sides:
1=1/3d-2
+2 +2
--------------
3 = 1/3d
Then to get the d on its own, we multiply each side by 3
3=1/3d

At the end of a snow storm, Michael saw there was a lot of snow on his front lawn. The temperature increased and the snow began to melt at a steady rate. The depth of snow on Michael's lawn, in inches, can be modeled by the equation S=-2t+20,S=−2t+20, where tt is the time, in hours, after the snow stopped falling. What is the xx-intercept of the equation and what is its interpretation in the context of the problem?
Answer:
x-intercept equals 10
interpretation is that, after 10 hours, all of the snow will be melted
Step-by-step explanation:
The linear equation can be used to solve to get the value of unknown quantities. The x-intercept of the equation is 10 and its interpretation in the context of the problem is that it shows zero depth at t = 10.
What is a Linear equation?A linear equation is a equation that has degree as one.
To find the solution of n unknown quantities n number of equations with n number of variables are required.
The given equation for the depth of the snow is as below,
S = -2t + 20
Here, S is the depth at a time t.
Suppose S is on y-axis and t on the x-axis.
Since the x-intercept of an equation is found by Substituting y = 0.
Substitute S = 0 in the given equation to get,
0 = -2t + 20
=> 2t = 20
=> t = 10
It means at t = 20, the depth of snow will become zero.
Hence, the x-intercept for the given case is 10 and it shows zero depth of the snow.

What are two points that represent Justine's function for the yards left to hike in terms of the hours she's spent hiking?
Answer:
(0,320) and (4,0)
Step-by-step explanation:
The question has missing details. So, I've added the complete question as an attachment.
From the question, we understand that:
Justine started when Michael was 320 yards from the top.
This coordinate can be represented as (0,320)
0 represents the time Justine started and 320 represents the number of yards left.
Every minute, Justine covers 80 yards.
This implies that:
At 1 minute, Justine will have: (320 - 80) yards left
At 2 minutes, Justine will have: (320 - 80 - 80) yards left
At 3 minutes, Justine will have: (320 - 80 - 80 - 80) yards left
At n minutes, Justine will have (320 - 80n) yards left
So, possible coordinates are:
[tex](x_1,y_1) = (0,320)[/tex]
[tex](x_2,y_2) = (1,320-80*1) = (1,240)[/tex]
[tex](x_3,y_3) = (2,320-80*2) = (2,160)[/tex]
[tex](x_3,y_3) = (3,320-80*3) = (3,80)[/tex]
[tex](x_4,y_4) = (4,320-80*4) = (4,0)[/tex]
Answer:
Select any two pairs of values from the given table. But, for simplicity, it’s a good idea to select coordinates with integer values. So, two points that represent Justine’s function for the yards left to hike in terms of the hours she’s spent hiking are (1, 270) and (2, 150).

What is the interest earned of 600$ at 5% for 2years
Simple interest , I, is calculated by multiplying the principal, P, by the rate,r, by the time, t, in years:
I = P * r * t
Here, P = $600
r = 0.05 (decimal value for 5%)
t = 2 years
Part a)
The interest earned will be:
I = P * r * t
I = 600 * 0.05 * 2
I = $60
Part b)
The balance in the account will be $600 plus the interest earned or:
$600 + 60 = $660
Answer:
$60 interest
Step-by-step explanation:
divide 5 by 100 = 0.05
multiply 0.05 by 600 = 30
then multiply 30 by the number of years (2) 30×2= 60
60 dollars interest
