[tex]49 = \frac{x}{7} [/tex]
Multiply both sides of the equation by 7
[tex]49 \times 7 = \frac{x}{ \cancel7} \times \cancel7[/tex]
[tex]343 = x[/tex]
[tex]x = 343[/tex]

Answer:
Step-by-step explanation:
3x^2 + 8x - 16 - SOMETHING = x^2 - 4
Re-arranging left and right:
SOMETHING = 3x^2 + 8x - 16 - x^2 + 4
= (3x^2 - x^2) + 8x - 16 + 4
= 2x^2 + 8x - 12
Answer:
Original expression: [tex]3x^2+8x-16[/tex]
Let [tex]a[/tex] be the quantity Amir subtracted from the original expression.
Expression after subtraction: [tex]x^2-4[/tex]
[tex]\implies (3x^2+8x-16)-a=x^2-4[/tex]
Solve for [tex]a[/tex]:
[tex]\implies 3x^2+8x-16-a=x^2-4[/tex]
Add 4 to both sides:
[tex]\implies 3x^2+8x-12-a=x^2[/tex]
Subtract [tex]x^2[/tex] from both sides:
[tex]\implies 2x^2+8x-12-a=0[/tex]
Add [tex]a[/tex] to both sides:
[tex]\implies 2x^2+8x-12=a[/tex]
Therefore, Amir subtracted [tex]2x^2+8x-12[/tex] from the original expression.

Answer:
Step-by-step explanation:
Two possible equations, depending on how you read the question.
1. Is there a shipping and handling per disc?
If so:
[tex]C = 13n + 1.95n[/tex]
2. Shipping and handling is only charged once?
If so:
[tex]C=13n+1.95[/tex]

PLEASE HELP! math is stressing me
Answer:
Sin theta= a/c
= 5/7.8
= 0.64
= 1
Step-by-step explanation:
Lets find the hypotenuse first by applying Pythagorean theorem.
a^2+b^2=c^2
(6)^2+(5)^2=c^2
36+25=c^2
61=c^2 (FIND SQUARE ROOT)
7.8=c
Sin theta= a/c
= 5/7.8
= 0.64
= 1
Cos theta= b/c
= 6/7.8
Tan theta= a/b
= 5/6

Step-by-step explanation:
Vertex of function f(x)
From inspection of the graph, the vertex of f(x) is (2, 1)
Vertex of function g(x)
Given: [tex]g(x)=2x^2-8x+1[/tex]
Standard form of a parabola is [tex]y=ax^2+bx+c[/tex]
Vertex form of a parabola is [tex]y=a(x-h)^2+k[/tex]
(where (h, k) is the vertex)
To convert from standard to vertex form, complete the square.
Set the equation to zero:
[tex]\implies 2x^2-8x+1=0[/tex]
Add 7 to both sides:
[tex]\implies 2x^2-8x+8=7[/tex]
Factor out common term 2 on left side:
[tex]\implies 2(x^2-4x+4)=7[/tex]
Factor expression inside brackets:
[tex]\implies 2(x-2)^2=7[/tex]
Subtract 7 from both sides:
[tex]\implies 2(x-2)^2-7=0[/tex]
Therefore:
[tex]g(x)=2(x-2)^2-7[/tex]
So the vertex of g(x) is (2, -7)
Solution
y-value of the vertex of f(x) = 1
y-value of the vertex of g(x) = -7
y-value of vertex of f(x) subtracted from the y-value of the vertex of g(x):
-7 - 1 = -8
The solution to an absolute value inequality is shown on the graph below.

Insert three arithmetic means between -16 and 4.
Answer:
Three arithmetic means between -16 and 4 are : 20 , 10 and [tex]\frac{20}{3}[/tex]
Step-by-step explanation:
we have to find out three arithmetic means between -16 and 4
-16 , ____ , ____ , ____ 4
so , lets take the mean like this ,
-16 , -16+d , -16+2d ,-16+3d , 4
First mean -: -16 +d = 4
d= 4+16
d = 20
second mean -: -16 +2d = 4
2d= 4+16 = 20
d= [tex]\frac{20}{2}[/tex]
d= 10
third mean -: -16+3d = 4
3d = 20
d=[tex]\frac{20}{3}[/tex]
Therefore , all the three arithmetic means between -16 ad 4 are 10 , 20 and [tex]\frac{20}{3}[/tex] .

17. Carol and Cathy are each saving money for a vacation. Carol started with $25 and saves
$7.50 a week. Cathy started with $10 and saves $10 a week. When will they have saved
the same amount?
Answer:
6 weeks
Step-by-step explanation:
Let x represent the weeks
[tex]25=10+ (10x-7.5x = 2.5)[/tex]
[tex]25-10=2.5x = 15[/tex]
[tex]\frac{15}{2.5}=x \\(150/25)\\x=6[/tex]
Carol and Cathy will have same saved amount after 6 weeks.
What do you mean by algebraic expressions ?
Algebraic expression is an equation which consists of variables and the arithmetic operations such as division , multiplication , etc.
It is given that Carol started with $25 and saved per week an amount of $7.50 whereas Cathy started with $10 and saved per week amount of $10.
Let's assume that after x no. of weeks they will have same saved amount.
So , we can write an algebraic expression which is :
25 + (7.5 × x) = 10 + (10 × x)
Now , reordering the like terms we get :
10x - 7.5 x = 25 - 10
Simplifying this we get :
2.5 x = 15
or
x = 15 ÷2.5
or
x = 6 weeks
Therefore , Carol and Cathy will have same saved amount after 6 weeks.

Snow is falling steadily in Syracuse, New York. After 2 hours, 4 inches of snow has fallen
If it continues to snow at the same rate, how many inches of snow would you expect after 6.5 hours? If you get stuck, you can use the table to help.
Answer:
13
Step-by-step explanation:
2 hours = 4 inches
2/2 equals 1 hour
4/2 equals 2 inches
2 inches of snow per hour
6.5*2 is 13
you should expect 13 inches of snow in 6.5 hours

Explain why the condition a=/ 0 must be stated to ensure that y = ax2 + bx + c is a quadratic relation.
Answer:
a = 0 makes the equation a linear equation, not quadratic
Step-by-step explanation:
A polynomial expression is quadratic if and only if its highest degree is 2. If the coefficient of the squared term is zero, then the polynomial does not contain a term of degree 2, so is not a quadratic. The coefficient of the squared term must be non-zero.
