Answer:
D. 398
Step-by-step explanation:
The way to solve this equation is to subtract 7,272 on both sides to get your x-value. You should get 398 as your x value and your answer.
Express (x + 10)^2 as a trinomial in standard form.
Answer:
x2-20x+100
Step-by-step explanation:
You have to factor the expression in order to get your answer
Do this by expanding out the expression: (x-10)(x-10) Then factor by multiplying each of the components! Use the FOIL acronym to help you. FOIL stands for First, Outer, Inner, Last. Meaning multiply the first numbers of the expressions together, then the outers, then the inner two numbers, then the last two numbers of the expression.
Multiply x and x to get , multiply x and -10 to get -10x, multiply -10 and x to get -10x, multiply -10 and -10 to get 100. Add them all together: . Then combine like terms
The required trinomial in standard form is x²+20x+100.
Trinomial:Important information:
The expression is the [tex](x+10)^2[/tex].Using the formula [tex](a+b)^2=a^2+2ab+b^2[/tex], we get
[tex](x+10)^2=(x)^2+2(x)(10)+(10)^2[/tex]
[tex](x+10)^2=x^2+20x+100[/tex]
Therefore, the required trinomial in standard form is x²+20x+100.

What should be the first step in adding these equations to eliminate y?
8x + 3y = 2
+ 4x - 6y= -7
O A. Multiply the top equation by 4.
O B. Multiply the bottom equation by 8.
C. Multiply the bottom equation by 2.
D. Multiply the top equation by 2.
D. Multiply the top equation by 2.
Answer:
D
Step-by-step explanation:
Given the 2 equations
8x + 3y = 2 → (1)
4x - 6y = - 7 → (2)
Multiplying the top equation (1) by 2 and adding to (2) will eliminate y
16x + 6y = 4 → (3)
Add (2) and (3) term by term to eliminate y
20x + 0 = - 3
20x = - 3 ( y has been eliminated )

What is the solution to the system of equations below? {2y=x+63x=y+7 (5, 4) (20, 13) (13, 20) (4, 5)
Answer:
(4,5)
Step-by-step explanation:
Let's solve your system by substitution.
2y=x+6;3x=y+7
Step: Solve2y=x+6for x:
2y=x+6
2y+−x=x+6+−x(Add -x to both sides)
−x+2y=6
−x+2y+−2y=6+−2y(Add -2y to both sides)
−x=−2y+6
−x
−1
=
−2y+6
−1
(Divide both sides by -1)
x=2y−6
Step: Substitute2y−6forxin3x=y+7:
3x=y+7
3(2y−6)=y+7
6y−18=y+7(Simplify both sides of the equation)
6y−18+−y=y+7+−y(Add -y to both sides)
5y−18=7
5y−18+18=7+18(Add 18 to both sides)
5y=25
5y
5
=
25
5
(Divide both sides by 5)
y=5
Step: Substitute 5 for y in x=2y−6:
x=2y−6
x=(2)(5)−6
x=4(Simplify both sides of the equation)
using the elimination method how do I find x and y for the following problem:
3x+5y=-1
x + 5y = 4
Answer:
x is equal to -3, and y is equal to eight fifths, or 1.6
Step-by-step explanation:
Solving by elimination means to add or subtract one of the equations from the other, eliminating one of their common terms.
Because both of the provided ones have the term 5y (and no other y terms), let's use subtraction:
3x + 5y = -1
- ( x + 5y = 5 )
2x + 0 = -6
Which we can solve pretty quick:
2x = -6
x = -3
We can now solve either of the original equations for y:
x + 5y = 5
-3 + 5y = 5
5y = 8
y = 8/5, or 1.6
To make sure we're correct, let's test our results in the other equation:
3x + 5y = -1
3 × -3 + 5 × 8/5 = -1
-9 + 8 = -1
-1 = -1
So we're good!
What do you add to
5 3/7 to make 8?
Answer:
2 4/7
Step-by-step explanation:
3/7+4/7= 7/7 or 1 whole
So you add that to the 5 and get 6, then you need 2 to get to 8 because 6+2=8
Hope this helped!!!
Answer:
2 4/7
Step-by-step explanation:
let n = number to add to 5 3/7
change 5 3/7 to improper fraction: 38
7
change 8 to become 56
7
create equation:
38 + n = 56
7 7
n = 56 - 38
7 7
n = 18 or 2 4/7
7
check: 5 3 + 2 4 = 8
7 7
5 + 2 = 7 and 3/7 + 4/7 = 1
7 + 1 = 8
A 16-ounce package of cereal costs $4.00. What is the unit cost?
Answer:
$0.25/1oz
Step-by-step explanation:
$4.00 / 16oz = $0.25 per ounce
Answer:
The answer is D) $0.25 for every 1 oz
Step-by-step explanation:
In order to find a unit cost of something, you divide the amount of money per item, by the amount of the product. So, you divide 4/16 and get .25. Then you know already that that is the unit cost. So, every 1 oz of the product costs 25 cents. Hope this helps :)

Tell whether the rates are equivalent. 0.4 kilometer for every 15 minutes 0.6 kilometer for every 20 minutes
Answer:
no they are not equivalent
Step-by-step explanation:
0.4/15 = 0.026
so for every minute they travel 0.026km
0.6/20 = 0.03
so for every minute they travel 0.03km
so they are not the same/equivalent
Which shows the best use of the associative and commutative properties to
make simplifying 2.4 + 13 – 5 + 3.6 +7 easier?
O A. (2.4 + 13) + (-5 +3.6 + 7)
O B. (2.4 + (-5) + 13) + (7 + 3.6)

O D. (2.4+ 3.6) + [13 +7+(-5)]
Answer:
D
Step-by-step explanation:
So the associative and commutative properties basically say That you can change the orders of the numbers and the answer won't change (for multiplication and addition).
Your answer would be D because they added the numbers with a decimal place together, it makes it easier to look at, and add in your head.

What is the value of x when g(h(x)) = 4?
Answer:4
Step-by-step explanation:
I Took the test
The value of the x in g(h(x)) = 4 is 4 if the g⁻¹(4) = 2 and at x = 4 h(x) = 2 option (C) is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have functions g(x) and h(x) shown in the figure.
g(h(x)) = 4
Taking the inverse of a function:
h(x) = g⁻¹(4)
From the set of functions g(x)
(2, 4) belongs to g(x)
(4, 2) belongs to g⁻¹(x)
g⁻¹(4) = 2
h(x) = 2
x = 4 (from the function h(x) data set)
Thus, the value of the x in g(h(x)) = 4 is 4 if the g⁻¹(4) = 2 and at x = 4 h(x) = 2 option (C) is correct.

so SQR or x is 55 degrees
Answer:
x = 55°Step-by-step explanation:
Straight angle equals 180°
PQR = 180°
PQR = PQS + SQR angle addition postulate
180° = 125° + xx = 180° - 125°x = 55°
