Only true statement for function f(x) =
is <u>c. if the value of x increases by 1, the value of y will triple</u>.
<u>Step-by-step explanation:</u>
<u>a. the function decreases
</u>
f(x) =
, For value of x<1 function decreases and for x>1 function increases . False statement .
<u>c. if the value of x increases by 1, the value of y will triple.
</u>
For value of x increases by 1 we have ,
. True statement.
<u>b. the function has a y-intercept of (0, 3)
</u>
At y intercept x=0, f(x) =
,
. Function has a y-intercept of (0,3). False statement.
<u>d. the function contains the point (1, 4)</u>
At x=1,
. Function contains (1,12) not (1,4) . False statement.
Answer:
Step-by-step explanation:
<u>Area of the larger circle:</u>
<u>The shaded area:</u>
- π(2r)² - πr² = 75
- 3πr² = 75
- πr² = 25
<u>Area of the larger circle:</u>
If you are talking about the area and perimeter of one of the triangular faces...
8 x 1.2 = 9.6
6 x 1.2 = 7.2
Perimeter = 9.6 + 7.2 + 7.2 = 24
Area = Linear Scale Factor²
1.2² = 1.44
7 x 1.44 = 10.08 (units)²
Answer: There were 7 children
Step-by-step explanation:
Let's use <em>x </em>to represent the children and <em>y </em>to represent the adults.
We know they combine to make a group of 25 people so x+y=25
We also know that they paid $201 and that there is $3 per child and $10 for adults so 3x+10y=201
I will solve by substitution.
Solve for y in the first equation

Sub in our value for y into the other equation and solve for x

Step 1) Simplify

Step 2) Subtract 250 from both sides

Step 3) Divide both sides by -7

Yes, (3,-1) is a solution to the graphed system of inequalities.
<h3>What are system of inequalities?</h3>
When mathematical expressions are compared, with non-strict equality, then such mathematical statements are called mathematical inequalties.
A collection of inequalities for which we consider a common solution for all inequalities is called a system of inequalities.
As we can see in the graph that the two lines are interest in the second quadrant at point such as(x, -y).
So, the point will be a solution also because it lies in the shaded region.
Therefore, Yes, (3,-1) is a solution to the graphed system of inequalities.
