Functions f (solid) and g (dashed) are graphed. What is the equation of g in terms of f?
HELP ME PLEASE I NEED HELP
Answers
Answer:
-f(-x)
Step-by-step explanation:
We need to reflect this across both the x and y axis
which means that we need it to look kind of like this -f(-x)
given f(x) = 2x - 3, find f(½)
Answers
f(1/2)=2(1/2)-3
f(1/2)= 1-3
f(1/2)= -2
f(1/2) = 2(1/2) - 3
f (1/2) = -2
The first snack is 270 calories for 3 servings, and the second snack is 450 calories How many servings does the snack have to have in order to equivalent to the first snack?
Answers
Answer:
5 servings
Step-by-step explanation:
Given that:
For a particular first snack to be = 270 calories;
the servings = 3
Then, for the second snack, the calories = 450.
To estimate the servings for the second snack; we need to equate the first snack with the second snack.
Let y be the value of the unknown second snack
Then:
270 calories = 3 servings
450 calories = y servings
y servings = (450 calories × 3 servings) / 270 calories
y servings = 5 servings
Thus; the second snack needs to have 5 servings in order to be equivalent to the first snack

Hamburger Heaven is having a lunch special where customers buy one 3/4-pound cheeseburger and get one free. If they set aside 130 2/3 pounds of meat, how many 3/4-pound cheeseburgers can they make?
Answers
Answer:
174 cheeseburgers
Step-by-step explanation:
The computation of the number of 3 by 4 pound cheese burgers made is shown below:
3 by 4 would be written as 0.75 pound
And, 130 2 ÷ 3 = 130.66667 pounds
Now the number of 3 by 4 pound cheese burgers made is
= 130.66667 pounds ÷ 0.75 pound
= 174.22
= 174 cheeseburgers

Step-by-step explanation:
90+2x+x=180
3x=90
x=30
Answer:
30
Step-by-step explanation:
First we can find the total angle that we are "adding" to. This total angle is 180 degrees. Now since there is a right angle, H,E,G, we can remove 90 from that total to get 90. Now for x. Since there is a total of 3 x's, we divide 90 by 3 to get 30.

To find:
The simplified form of the given expression.
Solution:
We have,
[tex]-3\sqrt{50a^2b^2}[/tex]
It can be written as
[tex]=-3\sqrt{2\times 25a^2b^2}[/tex]
[tex]=-3\sqrt{2\times 5^2a^2b^2}[/tex]
Using the properties of radical and logarithm, we get
[tex]=-3\sqrt{2\times (5ab)^2}[/tex] [tex][\because (mn)^x=m^xn^x][/tex]
[tex]=-3\sqrt{2}\times \sqrt{(5ab)^2}[/tex] [tex][\because \sqrt{mn}=\sqrt{m}\sqrt{n}][/tex]
[tex]=-3\sqrt{2}\times 5ab[/tex]
[tex]=-15\sqrt{2}ab[/tex]
Therefore the simplified form of the given expression is [tex]-15\sqrt{2}ab[/tex].

What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
As, we know that The median (also called a midline or midsegment) is a line segment half-way between the two bases.
median = (a+ b ) / 2
So, 12.5 = (3x+1 + 15) / 2
12.5 = 3x + 16 / 2
25 = 3x + 16
3x = 9
x= 3
Hence, the value of x is 3.
