Sergio and Allen ate lunch together in the school cafeteria. Each boy ordered a cheeseburger with fries. Sergio only ate 1/7 of his cheeseburger, while Allen ate 3/7 of his cheeseburger. How much cheeseburger did they eat together?
Answer:
4/7
Step-by-step explanation:
The word together symbolizes that we are adding.
We add the numerators but keep the denominator the same since it is already the same.
1+3 is 4, so that is our new numerator.
1 3 4
__ + __ = __

Solve 4x + 8y = 16 for x.
O A. x=-8y + 4
O B. x= -2y+ 16
O C. x= -2y+ 4
D. X = 8y + 16
4x + 8y = 16
4x = 16 - 8y
4x = 4 (4 - 2y)
x = 4( 4 - 2y)/4
X = 4 - 2y
X = -2y + 4
1) Slope = -4, y-intercept = 2
Solve for y y + 7 = 9
Answer:
y = 2
Step-by-step explanation:
Given
y + 7 = 9 ( subtract 7 from both sides )
y = 2
Simplifying
y + 7 = 9
Reorder the terms:
7 + y = 9
Solving
7 + y = 9
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Add '-7' to each side of the equation.
7 + -7 + y = 9 + -7
Combine like terms: 7 + -7 = 0
0 + y = 9 + -7
y = 9 + -7
Combine like terms: 9 + -7 = 2
y = 2
Simplifying
y = 2

Write an equation that represents the transformations formed by the following items:
(a) horizontally shifting the graph 4 units to the left of f(x) = √x and then vertically compression by a factor of 1/3
(b) vertically stretching the graph by a factor of 4 of f(x) = √x and then vertically shifting the graph 3 units up
(c) horizontally stretching the graph of f(x) = √x by a factor of 2 and then vertically shifting the graph 6 units down
Answer:
a) [tex]f(x) = \frac{1}{3} \sqrt{x+4}[/tex]
b) [tex]f(x)=4\sqrt{x} + 3[/tex]
c) [tex]f(x) = 2\sqrt{x} -6[/tex]
Step-by-step explanation:
a) The function will be;
⇒ f (x) = 1/3 √(x + 4)
b) The function will be;
⇒ f (x) = 4√x + 3
c) The function will be;
⇒ f (x) = 2√x - 6
What is Translation?
A transformation that occurs when a figure is moved from one location to another location without changing its size or shape is called translation.
Given that;
There are some transformations are given.
Now,
For (a);
The function is horizontally shifting the graph 4 units to the left of
f(x) = √x.
So, The function become;
f (x) = √(x + 4)
And, Then vertically compression by a factor of 1/3.
So, The function become;
f (x) = 1/3 √(x + 4)
For b:
The function is vertically stretching the graph by a factor of 4 of f(x) = √x.
So, The function become;
f (x) = √x + 3
And, Then vertically shifting the graph 3 units up.
So, The function will be;
⇒ f (x) = 4√x + 3
For c;
The function is horizontally stretching the graph of f(x) = √x by a factor of 2.
So, The function become;
f (x) = 2√x
And, Then vertically shifting the graph 6 units down.
So, The function will be;
⇒ f (x) = 2√x - 6
Thus,
a) The function will be;
⇒ f (x) = 1/3 √(x + 4)
b) The function will be;
⇒ f (x) = 4√x + 3
c) The function will be;
⇒ f (x) = 2√x - 6

what is the coefficient of -2x+8=10
Step-by-step explanation:
Let's solve your equation step-by-step.
−2x+8=10
Step 1: Subtract 8 from both sides.
−2x+8−8=10−8
−2x=2
Step 2: Divide both sides by -2.
−2x−2=2−2
x=−1
Answer:
Answer:
-2
Step-by-step explanation:
The coefficient of an equation or expression is any constant that precedes a variable. So, in this case, the only variable is x, so the coefficient is the preceding number, -2.

Answer:
x = 20
Step-by-step explanation:
You can use Pythagorean theorem which is [tex]a^2 + b^2 = c^2[/tex]
a = 12
b = 16
and c would be x.
12^2 + 16^2 = c^2
144 + 256 = c^2
400 = c^2
square root
c = 20 or x = 20
Stella solves the following system of equations using the substitution method.
y=−4x−65x−y=10
What is the single-variable equation she solves after substituting?
5x−4x−6=10
5x−(−4x−6)=10
5x+10=−4x−6
5x+10=−(4x−6)
Answer:
5x-(-4x-6) = 10
Step-by-step explanation:
Given the expression
y=−4x−6 ..... 1
5x−y=10... 2
To get the required equation we will substitute equation 1 into 2
5x-y = 10
5x-(-4x-6) = 10
5x+4x+6 = 10
9x+6 = 10
9x = 4
x = 4/9the required equation is 5x-(-4x-6) = 10

Answer:
Triangle ADB is congruent to triangle DBC
Step-by-step explanation:
In geometry, a median of a triangle is a line segment joining a vertex to the midpoint of the opposite side, thus bisecting that side. Every triangle has exactly three medians, one from each vertex, and they all intersect each other at the triangle's centroid. In the case of isosceles and equilateral triangles, a median bisects any angle at a vertex whose two adjacent sides are equal in length.
Zoe paid 18.60 in sales tax and tips for dinner. The sales tax is 11% and she tipped 20%. What was the price of Zoe’s dinner before sales tax and tip?
Answer:
$60 was the price of Zoe's dinner, before sales tax and tip.
Step-by-step explanation:
Sales tax = 11% * original price = 0.11 * x= 0.11xTips for dinner = 20% * original price = 0.20 * x = 0.2x0.11x + 0.2x = 18.600.31x = 18.60x = 60$60 was the price of Zoe's dinner, before sales tax and tip.Answer:
$60 was the price of Zoe's dinner, before sales tax and tip.
Step-by-step explanation:
1. Sales tax = 11% times original price = 0.11 times x= 0.11x
2. Tips for dinner = 20% times original price = 0.20 times x = 0.2x
3. 0.11x + 0.2x = 18.60
4. 0.31x = 18.60
5. x = 60

the equation is 7x-3 over 9 > 8-2x
Answer:
solving the inequality we get [tex]\mathbf{x\geq 3}[/tex]
The graph is attached below.
Option C is correct option.
Step-by-step explanation:
We need to solve the inequality [tex]\frac{7x-3}{9}\geq 8-2x[/tex]
First we will solve the inequality to find value of x
Solving:
[tex]\frac{7x-3}{9}\geq 8-2x[/tex]
Step 1: Multiply both sides by 9
[tex]9(\frac{7x-3}{9})\geq 9(8-2x)\\7x-3\geq 72-18x[/tex]
Step 2: Adding 3 on both sides
[tex]7x-3+3\geq 72-18x+3\\7x\geq 75x-18x[/tex]
Step 3: Add 18x on both sides
[tex]7x+18x\geq 75-+18x\\25x\geq 75[/tex]
Step 4: Divide both sides by 25
[tex]\frac{25x}{25}\geq \frac{75}{25}\\x\geq 3[/tex]
So, solving the inequality we get [tex]\mathbf{x\geq 3}[/tex]
The graph is attached below.
Option C is correct option.

Sandy has 15 roses, 5 daisies, and 10 tulips. She wants to arrange all the flowers in bouquets. Each bouquet has the same number of flowers and the same type of flower. What is the greatest number of flowers that could be in a bouquet?
Answer:
5
Step-by-step explanation:
Sandy has 15 roses, 5 daises and 10 tulips
She wants to arrange the flower in such a way that each bouquet will have the same flower in it
Therefore the greatest number of flowers that will be in each bouquet is 5 flowers this is so inorder to make each bouquet contain equal number of flowers, this means that one bouquet must not be greater than the other.
