Can you please help me solve this and show the solution 4y⁴+6y?
Answer:
4y^4 + 6y = 256y + 6 = 262y
Step-by-step explanation:
Remove the variables for a second and think of the problem as a normal expression; 4^4 + 6
Simplify the first term; 4^4 = 256
Now, add 6; 256 + 6 = 262
Add back in the variable; 262y
Answer:
2y(2y+3)
Step-by-step explanation:
2y(2y) +6y factor 2y out of 4y^2
2y(2y)+2y(3) factor 2y out of 6y
2y(2y + 3) factor 2y out of 2y(2y)+2y(3)

The midpoint of the points R(-3,3) and S(1,6) is (-1,4.5).
What is a midpoint?A location that is halfway between two other points is considered to be a line segment's midway. The distance between the midway and each endpoint is the same.
The midpoint is calculated by using the formula:- ( x₁ + x₂ ) / 2 , ( y₁ + y₂ ) / 2.
Given points are R(-3,3) and S(1,6). The midpoint of the given points are calculated as below:-
M = (-3+1 ) / 2 , ( 3 + 9 ) / 2
M = ( -1,4.5)
Therefore, the midpoint of the points R(-3,3) and S(1,6) is (-1,4.5).

how do I find the value of x so f(x)=7
Answer:
x=5
Step-by-step explanation:
Here we are given with a graph.
we have been asked to find the value of x for which
As we know that , to find the value of x for the given value of f(x), we need to look onto the vertical axis, and mark a dot on the given value now draw a line perpendicular to vertical axis so that it cut the given straight line, and where they intersect draw another line perpendicular to the horizontal axis and you will get the value where it crosses the horizontal axis.
Hence we get x=5, then f(x)=7.

Answer:
C) 18 eating gummy bears
Step-by-step explanation:
The angles indicated with x-expressions are supplementary, so we have ...
(5x) +(7x+24) = 180
12x +24 = 180 . . . collect terms
x +2 = 15 . . . . . . divide by 12
x = 13 . . . . . . . . . subtract 2
Then the obtuse angle is ...
7x +24 = 7(13) +24 = 115
__
The angle marked with a y-expression is a corresponding angle to this, so has the same measure.
6y +7 = 115
6y = 108 . . . . subtract 7; next divide by 6
y = 18
Answer:
y=18
Step-by-step explanation:
5x+7x+24=180

Which functions represent the arithmetic sequence 8, 1.5, –5, –11.5 . . . ? Check all that apply.
f(n) = –6.5n + 14.5
f(n) = –1.5n + 9.5
f(n) = 6.5n + 1.5
f(1) = 8, f(n + 1) = f(n) – 6.5
f(1) = 8, f(n + 1) = f(n) – 1.5
f(1) = 8, f(n + 1) = f(n) + 6.5

Which value of x makes the equation -5x-(-7-4x) =-2(3x-4 true?
Answer:
x = 1/5
Step-by-step explanation:
Step 1: Write equation
-5x - (-7 - 4x) = -2(3x - 4)
Step 2: Solve for x
Distribute: -5x + 7 + 4x = -6x + 8Combine like terms: -x + 7 = -6x + 8Add 6x to both sides: 5x + 7 = 8Subtract 7 on both sides: 5x = 1Divide by 5 on both sides: x = 1/5Step 3: Check
Plug in x to verify it's a solution.
-5(1/5) - (-7 - 4(1/5)) = -2(3(1/5) - 4)
-1 - (-7 - 4/5) = -2(3/5 - 4)
-1 - (-39/5) = -2(-17/5)
-1 + 39/5 = 34/5
34/5 = 34/5

5+4(8n-8)=-1+6 for n
Answer:
n=1
Step-by-step explanation:
5+4(8n-8)=-1+6
5+32n-32=5
5+32n-32=5
-27+32n=5
32n=32
n=1
Answer:
n = 1
Step-by-step explanation:
5 + 4(8n - 8) = -1 + 6
First you have to distribute the 4 leaving the equation to look like this...
5 + 32n - 32 = -1 + 6
Now solve the constants (normal numbers without a variable)
-27 +32n = 5
+27 +27 You have to add 27 to BOTH sides
32n = 32
n = 1

13x - 15 = 12x + 16
Answer:
x = 31
Step-by-step explanation:
I will make the explanation easy for you to understand.
Step 1: Subtract 12x from both sides.
13x − 15 − 12x = 12x + 16 − 12x
x − 15 = 16
Step 2: Add 15 to both sides.
x − 15 + 15 = 16 + 15
x = 31

How do I do this problem im confused?
Answer: 54800
Step-by-step explanation: plug in 6 instead of t in both the equations. Start with the first equation

Then do the other equation
500t+200000
500(6)+200000= 20300
Subtract both

Two buses are traveling to a state park. One bus leaves the terminal at 4:00 pm, and travels at 40 miles per hour. The second bus
leaves the terminal at 5:00 p.m. and travels at 60 miles per hour.
At what time does the second bus catch up with the first bus?
Answer:
Step-by-step explanation:
When the second bus catches up to the first bus, this means that the distance they have travelled is equal.
So for bus 1, you know it travels at 40 miles per hour.
4pm = 0 miles
5pm = 40 miles
6 pm = 80 miles
7pm = 120 miles
For bus 2, you know it travels at 60 miles per hour
5pm = 0 miles
6pm = 60 miles
7pm = 120 miles.
So you can see that at 7pm, they will both have travelled 120 miles.

Find the measure of the exterior angle.
Answer:
108°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
2a is an exterior angle, thus
2a = a + 10 + 44 = a + 54 ( subtract a from both sides )
a = 54
Thus 2a = 2 × 54 = 108° ← exterior angle
Angle B=48 and angle E=x+4.

r=22
Step-by-step explanation:
Answer:
r = 22
Step-by-step explanation:
Given
[tex]\frac{1}{2}[/tex] r + 4 = [tex]\frac{3}{4}[/tex] r - [tex]\frac{3}{2}[/tex]
Multiply through by 4 to clear the fractions
2r + 16 = 3r - 6 ( subtract 2r from both sides )
16 = r - 6 ( add 6 to both sides )
22 = r
