Answer:
a = 11 , b = 2
Step-by-step explanation:
[tex]\frac{(4-\sqrt{5})(4+\sqrt{5}) }{2\sqrt{11}} = \frac{ \sqrt{a}}{y} \\Hence,\\\frac{4^2-(\sqrt{5})^2 }{2\sqrt{11}} = \frac{ \sqrt{a}}{y}\\\frac{16-5}{2\sqrt{11} } = \frac{ \sqrt{a}}{y}\\\frac{11}{2\sqrt{11}} = \frac{ \sqrt{a}}{y}\\\frac{\sqrt{11}*\sqrt{11} }{2\sqrt{11}} = \frac{ \sqrt{a}}{y}\\\frac{\sqrt{11} }{2} = \frac{ \sqrt{a}}{y}\\a=11,b =2[/tex]

Answer:
(x, y) = (-2.5, -4)
Step-by-step explanation:
Since you are given an expression for y, it is convenient to substitute that into the second equation.
2x -3(6x +11) = 7
2x -18x -33 = 7
-16x = 40 . . . . . . add 33
x = -40/16 = -2.5
Using the equation for y, we find ...
y = 6(-2.5) +11 = -15 +11 = -4
The solution is (x, y) = (-2.5, -4).
Solve for x(one solution,no solution,or infinite solutions) -2(3x+-1)=-6x-1

d. f (5) = 5 and f (-3) = -3
Answers
Answer:
C. f(5) = 13 and f(-3) = -3
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASStep-by-step explanation:
Step 1: Define
f(x) = 2x + 3
x = 5
x = -3
Step 2: Evaluate
x = 5
Substitute: f(5) = 2(5) + 3Multiply: f(5) = 10 + 3Add: f(5) = 13x = -3
Substitute: f(-3) = 2(-3) + 3Multiply: f(-3) = -6 + 3Add: f(-3) = -3We evaluate Separately.
Let x = 5
f(5) = 2(5) + 3
f(5) = 10 + 3
f(5) = 13
Now let x = -3.
f(-3) = 2(-3) + 3
f(-3) = -6 + 3
f(-3) = -3

An art teacher needs to cut out squares of paper for an art project from a left-over sheet of paper measuring 72 x 104 inches. What size would the biggest possible square be with sides of whole number length?
Answers
Answer:
7488 inches
Step-by-step explanation:
I think that this is the correct answer. The reason is that you have to multiply 72 x 104. I´m not 100% sure.
The required maximum area of the biggest possible square is with sides of a whole number length of 7396 inches².
What is surface area?The surface area of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the exterior of a 3D shape.
Here,
Area of the leftover sheet = 72 × 104 = 7488 inches²
area of the square = 7488
a² = 7488
a = 86.53
Somehow, for the biggest possible square to be with sides of whole number length,
The area is given as,
= 86²
= 7396 inches²
Thus, the required maximum area of the biggest possible square be with sides of whole number length 7396 inches².

On a coordinate plane, two parabolas open up. The solid-line parabola, labeled f of x, goes through (negative 2, 4), has a vertex at (0, 0), and goes through (2, 4). The dashed-line parabola, labeled g of x, goes through (3, 6), has a vertex at (5, 2), and goes through (7, 6).
What is the equation of the translated function, g(x), if
f(x) = x2?
A: g(x) = (x + 5)2 + 2
B: g(x) = (x + 2)2 + 5
C: g(x) = (x – 2)2 + 5
D: g(x) = (x – 5)2 + 2
Answers
Answer:
D
Step-by-step explanation:
Option 4.
The vertex form of a parabola is
where, a is a constant (h,k) is the vertex.
The given function is
The vertex of the function is (0,0) and it goes through (-2, 4) and (2, 4).
It is given that the vertex of function g(x) is at (5,2).
Substitute h=5 and k=2 in the equation.
g(x) is passed through (3, 6).
Divide both sides by 4.
Substitute a=1 in equation (2).
The function g(x) is g(x) =(x-2)2+5) .
Therefore, the correct option is 4.

Trudy bought a $20 prepaid long distance phone card. for every minute that she talks, $0.25 is deducted from her card. The function f(m)=20-0.25m represents the amount of money f(m) she has left after talking m minutes.FInd the zero and explain what it means in the context of the situation.
Answers
Answer:
Step-by-step explanation:
Given the function f(m)=20-0.25m to represent the amount of money f(m) she has left after talking m minutes, the zero of the equation can be gotten by setting f(m) to 0
f(m)=20-0.25m
0 =20-0.25m
-20 = -0.25m
m = -20/-0.25
m = 80
Hence Trudy will have talked for 80minutes if she has no money left
Evelyn drove 248 miles in 8 hours, If she continued at the same rate, how far would she travel in 6 hours?
Answers
Answer:
Continuing at the same rate, Evelyn would travel 186 miles.
Step-by-step explanation:
8/248 6/x. then cross multiply 8*x 248*6 = 8x = 1488 x = 186
Answer:
Evelyn will have driven 186 miles
Step-by-step explanation:
Step 1: 248 miles in 8 hours: Divide 248 by 8 in order to find how much miles she travels per hour. (248/8+31)
You should get 31 miles per 1hr.
Step 2: Multiply 31miles/hr by 6hrs in order to find the distance she travels. (31*6=186)
You should get 186 miles.
Mrs. Yamo bought 2 boxes of plastic bags. She had 1,988 craft sticks. She divided the craft sticks equally into 28 plastic bags for her students. How many sticks did Mrs. Yamo put in each bag?
Answers
Answer:
71 craft sticks per plastic bag
Step-by-step explanation:
Total craft sticks = 1,988
Total plastic bags = 28
She divided the craft sticks equally into 28 plastic bags for her students.
How many sticks did Mrs. Yamo put in each bag?
Craft sticks per plastic bag = Total craft sticks / Total plastic bags
= 1,988 / 28
= 71
Craft sticks per plastic bag = 71
Mrs. Yamo put 71 craft sticks in each plastic bag

James was able to correctly 11 major highways, 4 mountains, 86 major cities, and 9 bodies of water on a map. How many places on the map did James identify? Explain how you can use compatible numbers to help calculate the sum.
Answers
Answer:
The number of places correctly identified is 110 places
Step-by-step explanation:
The number of places he correctly identified will be;
11 + 4 + 86 + 9 = 110 places
By using compatible numbers, we refer to the fact that she use an estimate by making sure each of the numbers are closer to the nearest 10th or 5
so 4 will be 5
11 will be 10
86 will be 85
9 will be 10
Adding all of these together, we have
5 + 10 + 85 + 10 = 110
