Algebra 2 Honors High school
Answer:
x = 59
Step-by-step explanation:
[tex]\sqrt[3]{2x+7}[/tex] = 5 ( raise both sides to the power of 3 )
([tex]\sqrt[3]{2x+7}[/tex] )³ = 5³
2x + 7 = 125 ( subtract 7 from both sides )
2x = 118 ( divide both sides by 2 )
x = 59
Based on the Pythagorean Theorem, which of
the following is NOT true?
F b2 + a2 = c2
G b2 + c2 = a 2
H C2 - a2 = 62
J c2-b2 = a2
Answer:
G is not TRUE.
Step-by-step explanation:
using the law A+B = B+A
PYTHAGOREAN THEOREM
A²+B² =C² is equal to B² +A² = C²
So for A²,
B² - c² = A. remember if a positive number move from the left to the right over an equal sign it becomes negative and vice versa
B²
C² - A²= B²
A blood bank needs 5 people to help with a blood drive. 10 people have volunteered.
Find how many different groups of 5 can be formed from the 10 volunteers.

What is the permutation and combination?Permutation and Combination form the principles of counting and they are applied in various situations.
A permutation is a count of the different arrangements which can be made from the given set of things. In permutation the details matter, as the order or sequence is important.
Here given that,
A blood bank needs 5 people to help with a blood drive. 10 people have volunteered.
Here, We get;
The different groups of 5 can be formed from the 10 volunteers is,
⇒ ¹⁰C₅
⇒ 10! /5! 5!
⇒ 10×9×8×7×6 / 5×4×3×2
⇒ 252
Thus, The different groups of 5 can be formed from the 10 volunteers is,
⇒ 252

If Θ is in quadrant III and tanΘ >0, then x is negative. True or false.

True
Step-by-step explanation:
We know that [tex]tan\theta=\frac{sin\theta}{cos\theta}[/tex], [tex]sin\theta<0[/tex] in Quadrant III, and [tex]cos\theta<0[/tex] in Quadrant III. Thus, x is indeed negative since [tex]cos\theta<0[/tex].

Solve each system of equations using the elimination method
3x+4y=23
3x-2y=11
Answer: (x,y) = (5,2)
In other words, x = 5 and y = 2
====================================================
Explanation:
Subtract the equations straight down.
The x terms subtract to 3x-3x = 0x and they go away (hence the term "elimination").The y terms subtract to 4y-(-2y) = 6yThe right hand sides subtract to 23-11 = 12We end up with 6y = 12 which solves to y = 2 after dividing both sides by 6.
Now use this y value to find x.
If we used the first equation, then we have these steps
3x+4y = 23
3x+4(2) = 23
3x+8 = 23
3x = 23-8
3x = 15
x = 15/3
x = 5
Or we could use the second equation
3x-2y = 11
3x-2(2) = 11
3x-4 = 11
3x = 11+4
3x = 15
x = 15/3
x = 5
We get the same x value either way.
The solution is (x,y) = (5,2)
To check the answer, plug those coordinates into each equation. After simplifying, you should get the same number on both sides.
------------------
Check:
3x+4y = 23
3(5)+4(2) = 23
15+8 = 23
23 = 23 .. that works
and,
3x-2y = 11
3(5)-2(2) = 11
15 - 4 = 11
11 = 11 .. that works as well
Both original equations are true for those x and y values.
The solution is fully confirmed.
1.35 = 7x what is x ( other than 0.19285714 )
Hey there!
7x = 1.35
DIVIDE 7 to BOTH SIDES
7x/7 = 1.35/7
CANCEL out: 7/7 because it give you 1
KEEP: 1.35/7 because it give you the x-value
NEW EQUATION: x = 1.35/7
SIMPLIFY IT!
x = 0.192857
x ≈ 192,857/1,000,000
Therefore, your answer is:
x = 0.192857 or x = 192,857/1,000,000
Good luck on your assignment & enjoy your day!

Two – a third of a number is 4 more than 6 .Find the number
Answer:
-24
Step-by-step explanation:
First, at up an equation based on the problem:
2 - ⅓x = 4 + 6
Then, solve for x:
2 - ⅓x = 10
-⅓x = 8
x = -24
OR
2 = 10 + ⅓x
-8 = ⅓x
-24 = x

Answer:

In the given figure, find the value of x and y?
Answer:
x = 6 cmy ≈ 14.5°Step-by-step explanation:
The given diagram shows two points labeled B. Rename the one on segment CD as E.
We assume that AE is supposed to be the bisector of angle A. Since triangle ABC is isosceles, segment AE will be perpendicular to BC. In that case, triangle EBC is also isosceles, which means BE is also 6 cm.
Angle ABC is exterior to triangle BCD, so has a measure that is the sum of angles BDC and BCD. That is, angle ABC is 2y+y=3y. Angle CBE is also y, so angle ABE will be 3y+y=4y. This exterior angle to triangle BED is the sum of angles BED and BDE. We know BDE is 2y, so BED is 4y-2y=2y, which means triangle BED is isosceles and BD=BE=EC=x=6 cm.
__
Finding the measure of angle y is a bit tricky. We know that angle ABC is 3y, and angle EBC is y. If we say X is the midpoint of BC, where AE crosses BC, then we can write the trig relations ...
BX=BA·cos(3y)
BX=BE·cos(y)
Filling in the measures of BA and BE, we can equate expressions for BX to get ...
8cos(3y) = 6cos(y)
Using the trig identity for cos(3y), we can write this as ...
8(4cos(y)³ -3cos(y)) = 6cos(y)
32cos(y)³ -30cos(y) = 0
2cos(y)(16cos(y)² -15) = 0
This has solutions cos(y)=0 and cos(y) = ±√(15/16). We are interested in the positive solution only:
y = arccos(√15/16) ≈ 14.478°
The value of y is about 14.5°.

Answer:
S" = (-3/2, 9/2) = (-1.5, 4.5)
Step-by-step explanation:
The two dilation factors multiply each other, so the dilation of the final image relative to the initial figure is (3/2)(1/2) = 3/4.
S" = 3/4S = 3/4(-2, 6)
S" = (-3/2, 9/2) = (-1.5, 4.5)
The coordinates of point S" are (-3/2, 9/2) = (-1.5, 4.5)
What are Coordinates?This involves the use of one or more numbers to uniquely determine the position of the points or other geometric elements.
We have to multiply the dilation factors which will result in:
(3/2)(1/2) = 3/4.
S" = 3/4S = 3/4(-2, 6)
S" = (-3/2, 9/2) = (-1.5, 4.5)

WHAT IS THE VALUE OF X?
Answer:
x = 20
Step-by-step explanation:
180 - 45 = 5x + 35
180 - 45 = 135
5x + 35 = 135
5x + 35 - 35 = 135 - 35
5x = 100
5x/5 = 100/5
x = 20
Answer:
x=20
Step-by-step explantion:
180-45=135
we have,
135=5x+35
135-35=5x
100=5x

Use the sketch below and determine how many squares will be in Step 4.
From step 1 to step 2 they added 3 squares.
From step 2 to step 3 they added 5 squares.
Each step they add the next odd number in sequence: 3,5,7,9,etc.
So for step 4 they would add 7 more squares. Add 7 to the number of squares in step 3 for total squares:
7 + 9 = 16
step 4 will have 16 squares.
