Answer: g(-3) is 9 .
Step-by-step explanation:
So there are two functions and the first function says that to get the solution x has to be greater than 4 and -3 which is the input is not greater than 4 so you can't use that function to solve for g(-3).
using the second function , it says that x has to be less or equal to 4. And -3 is indeed less than 4 so you have to use the second function to solve for g(-3)
g(x) = -2x + 3 Input -3 and solve
g(-3) = -2(-3) + 3
g(-3) = 6 + 3
g(-3) = 9

Camilla has twice as many blueberry jelly beans as cherry jelly beans. After eating 10 pieces of each kind, she now haas three times as many blueberry jelly beans as cherry jelly beans. How many blueberry jelly beans did she originally have?
Answers
Answer:
40 blueberry jelly beans
Step-by-step explanation:
Let us represent blue berry beans = b
Cherry jelly beans = c
Camilla has twice as many blueberry jelly beans as cherry jelly beans.
Hence,
b = 2c .........Equation 1
After eating 10 pieces of each kind, she now has three times as many blueberry jelly beans as cherry jelly beans.
hence,
b - 10 = 3(c - 10)
b - 10 = 3c - 30
Collect like terms.
- 10 + 30 = 3c - b
20 = 3c - b .........Equation 2
Subtitute 2c for b in Equation 2
20 = 3c - 2c
20 = c
Hence, she had 20 cherry jelly beans.
In the question, we are asked to find how many blueberry jelly beans she had.
Hence,
b = 2c .........Equation 1
Substituting 20 for c in Equation 1
b = 2 × 20
b = 40
Therefore, she originally had 40 blueberry jelly beans
Planes A and B both intersect plane S. Vertical plane S intersects horizontal plane A and horizontal plane B. Plane S and plane A intersect at line f. Line f contains points N and K. Plane S and plane B intersect at line g. Line g contains points P and Q. Line d intersects plane A at point L. Which statements are true based on the diagram? Select three options. Points N and K are on plane A and plane S. Points P and M are on plane B and plane S. Point P is the intersection of line n and line g. Points M, P, and Q are noncollinear. Line d intersects plane A at point N.
Answers
Answer:
Points N and K are on a plane A and plane S ( True )
Points P and M are on a plane B and plane S
Point P is the intersection of line n and line g ( True )
Points M, P, and Q are noncollinear ( True )
Line d intersects plane A at point N.
Step-by-step explanation:
Just took the test and got it right :)
The true are 1, 3, 4 and false are 2, 5.
To choose the statement are true or false.
What is plane?A surface in which if any two points are chosen a straight line joining them lies completely in that surface. A plane is a flat, two-dimensional surface that prolongs infinitely far.
Given that:
1. Points N and K are on plane A and plane S.
From that points N and K are on the plane A and on the plane S. Thus, this option is true.
2. Points P and M are on plane B and plane S.
From points P and M are on the plane B, but point M doesn't lie on the plane S. So, this option is false.
3. Point P is the intersection of line n and line g.
Point P lies on the line n as well as on the line g, therefore it is the point of intersection of these two lines. This option is true.
4. Points M, P, and Q are noncollinear.
It is true, because points M, P and Q do not lie on the same line at one time, that means they are noncollinear.
5. Line d intersects plane A at point N.
From the line d intersects plane S at point L, not at point N, then this option is false.

Answer:

Step-by-step explanation:

x=5
Answer:
One solution, x=5.
Step-by-step explanation:
4x-8=12
To find the solution we have to find the value of x.
to find the value of x, we have to add 8 to BOTH sides.
4x-8=12 (Why add 8? because we have to do the opposite of the sign!)
+8 +8
4x=20
Now to find X we have to ISOLATE IT.
So we take out 4, How? We do the opposite to both sides.
4/4 Cancels out
20/4 = 5
So now we know X=5
Insert in the main problem to check.
4(5)-8=12

Point T is on line segment SU. Given ST = 2x + 6, TU = 4, and SU = 4x, determine the numerical length of ST
Answers
Step-by-step explanation:
Point T is between Points S and U, where all 3 points are collinear.
Therefore ST + TU must be equal to SU.
(2x + 6) + 4 = 4x
2x + 10 = 4x
2x = 10
x = 5.
Hence, length of ST = 2(5) + 6 = 16.
The length of ST will be 16 units.
What is a line segment ?A line segment is basically a line with two end points.
two or more than two co-linear points is needed to form a line segment.
In the given question
Line segment is SU
Point T is in between point S and point U here all the points are co-linear
SU = ST + TU
4x = (2x + 6) + 4
4x = 2x + 10
2x = 10
x = 5
∴ The length of ST = 2x + 6 = (2×5) + 6 = 16 units

Given:
Distance = 15 1/2 miles
Time = 1/3 hour
Distance =?
Time = 1 hour
Distance : time
15 1/2 miles : 1/3 hour = ? miles : 1 hour
31/2 miles ÷ 1/3 bout = x miles / 1 hour
31/2 × 3/1 = x / 1

Write a paragraph proving that x=8 in the equation 7x-28=28
Answers
Answer:
[see below]
Step-by-step explanation:
We would need to undo the equation and preform inverse operations to get 'x' on one side. First, we need to get rid of 28 by adding 28 to each side. This would leave us with 7x on one side. Then, we wound divide each side by 7. This would leave us with 'x = 8'. If we plugged in the value, then it would satisfy the equation.
[tex]7x-28=28\\\\7x-28+28=28+28\\\\7x=56\\\\\frac{7x=56}{7}\\\\ \boxed{x=8}[/tex]
Checking the answer:

Answer: 3⁴
Explanation: Exponential form contains a base and an exponent.
The base is the number that is multiplied.
So in this case, 3 is the base.
Next we write the exponent which is the
number of times that the base is multiplied.
Since 3 is multiplied four times, the exponent is 4.
So in exponential form, 3 · 3 · 3 · 3 can be written as 3⁴.

If your car can drive 433 miles on a full tank of gas, find the miles per gallon if your gas tank holds 17.2 gallons? How much does it cost to fill your tank if gas is $2.85 per gallon?
Answers
Answer:
-25.17 miles per gallon.
-It costs $49.02 to fill your tank.
Step-by-step explanation:
-To find the miles per gallon, you can use a rule of three:
17.2 gallons → 433 miles
1 gallon → x
x=(1*433)/17.2= 25.17
If your gas tank holds 17.2 gallons, you car can drive 25.17 miles per gallon.
-To find the cost to fill your tank, you have to multiply the price per gallon for the amount of gallons that the tank can hold:
$2.85*17.2=$49.02
It costs $49.02 to fill your tank.
