D. -15x + 6x? - X+9
Please I need help immediately
Note: Your answer choices remain a little unclear. But, I have solved the concept and solution, so you can easily figure it out.
Answer:
[tex]\left(-7x^0+5x^2-x+6\right)-\left(-8x^2+x+3\right)=13x^2-2x-4[/tex]
Step-by-step explanation:
Given the expression
[tex]\left(-7x^0+5x^2-x+6\right)-\left(-8x^2+x+3\right)[/tex]
solving the expression
[tex]=-7x^0+5x^2-x+6-\left(-8x^2+x+3\right)[/tex]
apply the rule: [tex]a^0=1,\:a\ne \:0[/tex]
[tex]=-7+5x^2-x+6-\left(-8x^2+x+3\right)[/tex]
[tex]=-7+5x^2-x+6+8x^2-x-3[/tex]
simplify
[tex]=13x^2-2x-4[/tex]
Therefore, the simplified form is:
[tex]\left(-7x^0+5x^2-x+6\right)-\left(-8x^2+x+3\right)=13x^2-2x-4[/tex]
Note: Your answer choices remain a little unclear. But, I have solved the concept and solution, so you can easily figure it out.

Answer:
13.7
Step-by-step explanation:
Pythagorean theorem converse
Answer:
The value of x is 13.7.
Step-by-step explanation:
☆We are going to use the Pythagorean theorem to solve this.
☆Pythagorean Theorem:
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
☆Remmeber: a = leg, b = leg, c = hypotenuse or the diagonal.
☆Let's plug in according to the pythagorean theorem and solve!
[tex] {a}^{2} + {b}^{2} = {c}^{2} \\ {x}^{2} + {9.2}^{2} = {16.5}^{2} \\ {x}^{2} + 84.64 = 272.25 \\ \frac{ \: \: \: \: \: \: \: \: - 84.64 = - 84.64}{ {x}^{2} = \sqrt{187.61} } \\ x = 13.7[/tex]
A baker needs 8 1/2 cups of flour for a sheet cake recipe. He has 4 2/3 cups of flour in a canister and buys 5 1/4 cups more.
How much flour does he have left after he makes the sheet cake?
Enter your answer as a mixed number in simplest form.
I dont know if i asked this question already but, I cant find it, but i need help now!
Answer: 1 5/12 cups of flour leftover
Step-by-step explanation: First, add 4 2/3 + 5 1/4. This gives you 9 11/12. 9 11/12 - 8 1/2 = 1 5/12.
The baker has [tex]1\frac{5}{12}[/tex] cups of flour left after making the sheet cake.
What is Fraction?A fraction represents a part of a whole.
Given that baker needs [tex]8\frac{1}{2}[/tex] cups of flour for a sheet cake recipe.
Baker has [tex]4\frac{2}{3}[/tex] cups of flour in a canister and buys [tex]5\frac{1}{4}[/tex] cups more.
The flour he has in total = [tex]4\frac{2}{3}[/tex] + [tex]5\frac{1}{4}[/tex]
=14/3 +21/4
=56+63/12
=119/12
To find how much flour the baker has left after making the sheet cake, we can subtract the amount needed from the total amount:
119/12 - 17/2 = (119 - 102) / 12 = 17/12
Therefore, the baker has [tex]1\frac{5}{12}[/tex] cups of flour left after making the sheet cake.

CAN SOMEONE HELP ME ??? This is areas and volumes of similar solids!!!!!! It’s urgent!!
Answer:
Step-by-step explanation:
let x be the unknown volume
5/7=50/x
x=70
Answer:
137.2 m³
Step-by-step explanation:
Given the ratio of sides a : b , then
ratio of volumes = a³ : b³
Here ratio of sides = 5 : 7 , then
ratio of volumes = 5³ : 7³ = 125 : 343
let x be the volume of the larger prism then by proportion
[tex]\frac{50}{125}[/tex] = [tex]\frac{x}{343}[/tex] ( cross- multiply )
125x = 17150 ( divide both sides by 125 )
x = 137.2
That is volume of larger prism is 137.2 m³

At the beginning of an environmental study, a forest covered an area of 1500 km . Since then, this area has decreased by 2.4% each year. Lett be the number of years since the start of the study. Let y be the area that the forest covers in km². Write an exponential function showing the relationship between y and t.
Answer:
[tex]y = 1500(0.024)^t[/tex]
Step-by-step explanation:
Given
[tex]a = 1500km[/tex] -- initial area
[tex]b = 2.4\%[/tex] -- rate
[tex]t = time[/tex] --- (years)
Required
Represent as an exponential function
An exponential function has the form:
[tex]y = ab^t[/tex]
Where
[tex]a = initial\ value[/tex]
[tex]b = rate[/tex] and [tex]b \ne 1[/tex]
[tex]t= time[/tex]
Substitute values for a and b, we have:
[tex]y = 1500 * (2.4\%)^t[/tex]
Convert percentage to decimal
[tex]y = 1500 * (0.024)^t[/tex]
[tex]y = 1500(0.024)^t[/tex]
Hence, the exponential function that represents the scenario is: [tex]y = 1500(0.024)^t[/tex]

find angle X on the given figure. m
Answer:
x = 61°
Step-by-step explanation:
In a rhombus, the diagonals bisect the angles, thus
∠ BAE = ∠ DAE = 29° , then ∠ A = 58°
∠ ADE = ∠ CDE = x , then ∠ D = 2x
In a rhombus, consecutive angles are supplementary
∠ A and ∠ D are consecutive angles , then
58 + 2x = 180 ( subtract 58 from both sides )
2x = 122 ( divide both sides by 2 )
x = 61°

What is the area, in square feet, of the trapezoid below?
Answer:
68.75
Step-by-step explanation:
Measure the length of the parallel sides and add them together. Then multiply this number by the height of the area. Then multiply by ½ or divide by two to find the square footage of the trapezoid.
13.6 + 5.9= 19.5
19.5 + 8 = 27.5
27.5 x 5 = 137.5
137.5 x 1/2 = 68.75

Determine which equation has the same solutions as the given equation.
x2 − 10x − 11 = 0
A.
(x − 5)2 = 21
B.
(x − 10)2 = 21
C.
(x − 10)2 = 36
D.
(x − 5)2 = 36
Answer:
D. [tex]\displaystyle (x - 5)^2 = 36[/tex]
Step-by-step explanation:
All you are doing is converting this Quadratic Equation to a Vertex Equation in Vertex Form by completing the square:
[tex]\displaystyle [\frac{b}{2}]^2 \\ \\ x^2 - 10x - 11 = 0 → x^2 - 10x + 25 - 36 = 0→ (x - 5)^2 - 36 = 0 \\ \\ (x - 5)^2 = 36[/tex]

The variable Q varies inversely as the cube of V. FK is the constant of variation, which equation represents this situation?
A. qv^3=k
B. q^3v=k
C. q/v^3=k
D. q^3/v=k
Step-by-step explanation:
When 2 variables are inversely proportional to each other, their product is a constant.
Since Q and V³ are inversely proportional to one another, QV³ = k. (B)

Step-by-step explanation:
5÷3 1/3
5/1 ÷ 10/3 because you have to get it into an improper fraction form in order to divide
5/1 × 3/10 because you have to multiply the first number by the reciprocal
5 and 10 cancel out so you would have 2 at the bottom

Lupe is the manager of the football team, and she has to plan a team dinner for Saturday night. She knows that one large pizza can feed 3 players and one sandwich tray can feed 4 players. Lupe needs to order enough food for the 72 players on the team. (a) Write a linear equation to represent the number of pizzas (x) and the number of sandwich trays (y) she could purchase to feed the football players.
Answer:
3x + 4y = 72
Step-by-step exlanation:
Number of pizzas = x
Number of sandwich trays = y
one large pizza can feed 3 players
one sandwich tray can feed 4 players
Total players = 72
The linear equation is
3x + 4y = 72
