what is 4x ^2 + 20x in square to form a perfect square trinomial
25/5
Step-by-step explanation:
first make the coefficient of x alone... So that you should take the 4 out... then you get 4times x squared + 5x then you should didvide the x term by 2(always) and then you get 5/2...So then the third term or the constant is tye square of that..
Solve the system of linear equations using elimination.
10x + 7y = 12
8x + 7y = 18
A) (3, 6)
B) (3, −6)
C) (−3, 6)
D) (−3, −6)
Answer:
C. (-3,6)
Step-by-step explanation:
Take 10x + 7y = 12 as first equation and 8x + 7y = 18 as second equation.
Subtracting both equations, you will get
10x + 7y - 8x - 7y = 12 - 18
2x = -6
x = -3
Substitute value of 'x' in any of the given equation :-
10x + 7y = 12
10 * -3 + 7y = 12
7y = 12 + 30
y = 42/7
y = 6
Answer:
C) (−3, 6)
Step-by-step explanation:
10x + 7y = 12 ___ (−3, 6)
10×(-3) + 7×6 = -30 + 42 = 42 - 30 = 12
8x + 7y = 18 ___ (−3, 6)
8×(-3) + 7×6 = -24 + 42 = 42 - 24 = 18
what is the value of 2^-3 as a fraction
Answer:
1/8
Step-by-step explanation:
2⁻³ = 1 / 2³ = 1 / (2*2*2) = 1/8
so the minus sign in the exponent means you can put that factor in the denominator without the minus sign.

if f(x) = 3/x + 2 - x-3, complete the following statement ( round your answer to the nearest hundredth):
f(7) =
Answer:
-1.67 is what I got
Step-by-step explanation:
solved it
The value of f(7) is -1.73 for the function f(x)=3/(x+2)-√x-3.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
A relation is a function if it has only One y-value for each x-value.
The given function is f(x)=3/(x+2)-√x-3
We need to find the value of f(7)
Replace x with 7 in the given function.
f(7)=3/7+2 - √7-3
f(7)=3/11-√4
=3/11-2
=3-22/11
=-19/11
=-1.73
Hence, the value of f(7) is -1.73 for the function f(x)=3/(x+2)-√x-3.

Answer:
Jerry's weight is 36kg and tom's weight is 66kg
Step-by-step explanation:
According to the given condition:
Let,tom's weight =x
Jerry's weight=y
So,
X=2y-6 ---(1)
X+y=102-----(2)
Put value of x from eq 1 in 2
2y-6+y=102
3y-6=102
3y=102+6
3y=108
Y=108/3=36
Jerry's weight is 36.
Put value of y in eq 1
X= 2(36) -6
X=72-6
X=66
So, Tom's weight is 66kg

8x4 x 3 = 96
4 x 3.5 x .5 x 2 = 14
96 + 14 = 110
Answer:
Total=110 in²
Step-by-step explanation:
Basically just do all of the shapes individually so the triangles would equal 7 each b/c 4x3.5 divided by 2 so those would be 14 and the rectangles eahc equal 32 so multiply that times 3 and u get 96 then add the two triangles (7 each) which gets u 110 in²

Step-by-step explanation:
Georgia has some 4-inch cubes like the one shown below. Georgia will put the cubes in the box shown below.
The question is incomplete. The complete question is :
Georgia has some 4-inch cubes like the one shown below. Georgia will put the cubes in the box shown below. What is the total number of cubes that Georgia needs to exactly cover the bottom of the box with a layer one cube deep?
Solution :
It is given that :
There are small cubes that has a dimension of 4 in x 4 in x 4 in.
There is also a box which has a dimension of 24 in x 20 in x 12 in.
We need to find out how many small cubes will Georgia need to cover the bottom of the box.
So, we need to find out the surface area of the one cube and the box.
Therefore, the surface area of one cube = side x side
= 4 inch x 4 inch
= 16 square inches
Similarly the area of the box can be find by = length x breath
= 24 in x 20 in
= 480 square inches
Therefore, dividing the area of the box by the area of the cube, we get
[tex]$=\frac{480}{16}$[/tex]
= 30
So Georgia will require exactly 30 cubes to cover the bottom of the box with a layer of one cube deep.
The measures of angles X and Y are the same, x degrees. The measure of angle Z is twice the measure of angle Y.
Answer:
If you're trying to find the measurement of angle z then it'd be 2x degrees, since its twice that of angle y, which is x degrees

This week at the farmers market the price of oranges per pound decreased by 20% compared to last week if the price of oranges this week is $3.89 which equation would represent the sales price of oranges?
Answer:
Orange per pound= $4.86
Step-by-step explanation:
Giving the following information:
Decrease rate= 20%
Price this week= $3.89 per pound
To calculate the price of oranges last week, we need to use the following formula:
Orange per pound= price this week / (1 - decrease rate)
Orange per pound= 3.89 / (1 - 0.8)
Orange per pound= $4.86
Draw fraction strips to add 1/4 and 1/6 Write an equation.
Answer:
fraction strips would just be;
1 box split into 12 parts because 12 is the common denominator, and 1/4 is equal to 3/12, so you would shade in 3 of the parts, and then 1/6 = 2/12, so you would shade in 2 parts. In the end, you should have a box (or rectangle) with 12 parts, and only 5 of those parts should be shaded in.
The equation would be as follows:
1/4+1/6 = 3/12+2/12 = 5/12

The number of views on a cat video and a dog video after they're uploaded are represented by the following tables:
Answer:
Cat video: exponential function
Dog video: linear function
Step-by-step explanation: I did it until I got it right.
The cat video is a exponential function and dog video is a linear function .
What is linear function?Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx. A linear function has one independent variable and one dependent variable. The independent variable is x and the dependent variable is y.
What is exponential function?An exponential function is a mathematical function of the following form:
f ( x ) = . where x is a variable, and a is a constant called the base of the function. The most commonly encountered exponential-function base is the transcendental number e , which is equal to approximately 2.71828.
According to the question
The tables for
Cat video
Time(month) Views
0 50
5 313
10 1950
15 12210
20 76300
So, as we can observe that values of views are increasing rapidly which can only be possible if function is exponential .
Dog video
Time(days) Views
0 10
6 452
12 889
18 1330
24 1770
So, as we can observe that values of views are increasing in constant pace which can be possible if function is linear .
We can plot graph of both the tables to check for the function nature .
Hence, the cat video is a exponential function and dog video is a linear function .
