what are the intersections between the lines y=x squared and 6x + 3y= 24?
Answers
Answer:
The intersection points between the functions are (-4,16) and (2,4)
Step-by-step explanation:
Intersection Between Functions
We are given the functions:
[tex]y=x^2[/tex]
[tex]6x+3y=24[/tex]
To find the intersections between them, we have to solve the system of equations. Let's start by simplifying the second equation by 3:
[tex]2x+y=8[/tex]
Now we substitute [tex]y=x^2[/tex] into this equation:
[tex]2x+x^2=8[/tex]
Solve the quadratic equation by any of the available methods.
Subtract 8:
[tex]2x+x^2-8=0[/tex]
Sort the polynomial:
[tex]x^2+2x-8=0[/tex]
Factor:
[tex](x+4)(x-2)=0[/tex]
Solve:
[tex]x=-4, x=2[/tex]
Now find the y-coordinate of each solution:
[tex]y=x^2=(-4)^2=16[/tex]
The point is (-4,16)
For x=2:
[tex]y=x^2=2^2=4[/tex]
The point is (2,4)
The intersection points between the functions are (-4,16) and (2,4)

How do I write this equation? Pls help ASP
Answers
This is a question about angles and equations! Let's see how to solve this.
The angle [tex]\angle PQR[/tex] is the sum of the angles [tex]\angle MQR[/tex] and [tex]\angle PQM[/tex]. So, we can do a equation with this information and solve it:
[tex]\angle PQR = \angle MQR + \angle PQM\\\\138x -1 = 115 + 23x -1\\138x - 23x = 115 + 1 - 1\\115x = 115\\x=\frac{115}{115} \\x= 1[/tex]
Therefore, the value of x is 1.
The function f has the property that as x gets closer and closer to 4, the values of f(x) get closer and closer to 7. Which of the following statements must be true?
Answers
Answer:
C
Step-by-step explanation:
x going to 4 is given by limx->4 and closer to 7 is given by =7
The correct statement is [tex]\lim_{x \to 4} f(x)[/tex] = 7.
What is function?An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given statement:
x gets closer and closer to 4, the values of f(x) get closer and closer to 7.
So, x gets closer and closer to 4 shows
x-> 4
and, f(x) get closer and closer to 7 shows
f(x)=7
Combining both we can write using the limit function x gets closer and closer to 4 require limit
[tex]\lim_{x \to 4} f(x)[/tex] = 7.

The children also want to go for a swim at one of the 4 beaches. How many different ways can the family plan a camping trip?
Answers
Answer:
62
Step-by-step explanation:
Camping trip different ways = No of campgrounds x campsites each campground
9 x 6 = 54
Hiking trip different ways = 4 (hiking trails)
Swimming different options = 4 (beaches)
Total ways of planning trip = 54 + 4 + 4 = 62
