Answer:
x= 9
Step-by-step explanation:
Solve (x + 9)^2 = 25.
square root of (x + 9)^2 = + or - square root of 25
1. Apply the square root property of equality:
2. Isolate the variable.
If x + 9 = 5, then x=
If x + 9 = -5, then x =
if x + 9 = 5 then x = -4
if x + 9 + -5 then x = -14
Answer:
if x + 9 = 5 then x = -4
if x + 9 + -5 then x = -14

Round 958.989730738 to the nearest hundred
Answer:
958.990
Step-by-step explanation:
958.990 is the Round off to the nearest hundred.
What is rounding a number to some specific place?Rounding some number to a specific value is making its value simpler (therefore losing accuracy), mostly done for better readability or accessibility.
Rounding to some place keeps it accurate on the left side of that place but rounded or sort of like trimmed from the right in terms of exact digits.
The digit 5 acts as a limit.
If the digit on right is 5, and after it there is only zeros or no value, then we round up (increase by 1, as we did in 347500 -> 34800 ) (Well there are many detailed rules of rounding)
WE have to Round 958.989730738 to the nearest hundred.
Hence, 958.990 is the Round off to the nearest hundred.

((2 x^2 + 1)^2)/(x^2)
Step-by-step explanation:
Simplify the following:
(2 x + 1/x)^2
Hint: | Put the fractions in 2 x + 1/x over a common denominator.

-3x - 4y = 5
- 2x + 3y = -8
Answer:
x = 1 ,y = -2
Step-by-step explanation:
Solve the following system:
{-4 y - 3 x = 5 | (equation 1)
3 y - 2 x = -8 | (equation 2)
Subtract 2/3 × (equation 1) from equation 2:
{-(3 x) - 4 y = 5 | (equation 1)
0 x+(17 y)/3 = -34/3 | (equation 2)
Multiply equation 2 by 3/17:
{-(3 x) - 4 y = 5 | (equation 1)
0 x+y = -2 | (equation 2)
Add 4 × (equation 2) to equation 1:
{-(3 x)+0 y = -3 | (equation 1)
0 x+y = -2 | (equation 2)
Divide equation 1 by -3:
{x+0 y = 1 | (equation 1)
0 x+y = -2 | (equation 2)
Collect results:
Answer: {x = 1 ,y = -2

Answer:
[tex]y=-\frac{3}{2}x+1[/tex]
Step-by-step explanation:
Slope-intercept form means
[tex]y=mx+c[/tex]
where m is given its the slope which is [tex]-\frac{3}{2}[/tex] and we have the coordinates x and y which is (4, -5) and we need to find the value of c which is the y-intercept so we insert all these values into the equation so ,
[tex]y=mx+c[/tex]
[tex]-5 = -\frac{3}{2}(4)+c[/tex]
[tex]-5=-6+c[/tex]
[tex]c=1[/tex]
now we know the value of slope which is given [tex]-\frac{3}{2}[/tex] and we found the value of which is 1 so we put these values into our original slope-intercept form equation
[tex]y=mx+c\\\\y=-\frac{3}{2}x+1[/tex]

Decide whether the pair of lines is parallel, perpendicular, or neither.
Ly: 2x + 3y = 8
L2:3x + 2y = 7
Choose the correct answer below.
A. The lines are neither parallel nor perpendicular.
B. The lines are perpendicular.
C. The lines are parallel.
Answer:
A
Step-by-step explanation:
We can solve for y for both of the lines' equations to get the point-slope form.
L1: [tex]y=\frac{-2}{3} x+\frac{8}{3}[/tex]
L2:[tex]y=\frac{-3}{2}x+\frac{7}{2}[/tex]
So, the slopes of the two lines are [tex]\frac{-2}{3}[/tex] and [tex]\frac{-3}{2}[/tex].
Remember that parallel lines have the same slope, and perpendicular lines have opposite and reciprocal slopes. These slopes are reciprocal but not opposite.

a prime number is a factor of 42 and 45 what is the prime number
Answer:
Common factors between the two numbers is 3 and 1.
Step-by-step explanation:
The factors of 42 are 42, 21, 14, 7, 6, 3, 2, 1.
The factors of 45 are 45, 15, 9, 5, 3, 1.
The value of the prime number which is a factor of 42 and 45 would be 3.
Used a concept of prime number that states,
A prime number is a whole number greater than 1 whose only factors are 1 and itself. A factor is a whole number that can be divided evenly into another number. Numbers that have more than two factors are called composite numbers.
Given that the two numbers are 42 and 45
Now, factors of numbers 42 and 45 are,
The Factor of 42 are
1, 2, 3, 6, 7, 14, 21, 42
And, The factors of 45 are
1, 3, 5, 9, 15, 45
So, the prime number that is a factor of 42 and 45 is 3.

A foreign country uses the stellar as its currency. Before a trip to that country, Mia wants to exchange $1700 to steller's. Which of Bank A and Bank B has the better exchange rate? How many more steller's would she get if she exchanged her $1700 at the better exchange rate instead of at the other rate?
Answer and explanation:
Stellar is a Brazilian cryptocurrency that is used to facilitate low cost and flexible payment. It was renamed lumens and is denoted XLM.
One stellar lumen is currently equal to $0.219096
For the purpose of the question and since it does not specify exchange rates for each bank, let's assume:
Bank A= 0.219097 to 1 US dollar
Bank B= 0.219099 to 1 US dollar
Using Bank A to exchange $1700 for stellars= $1700*0.219097= 372.464 stellars
Using Bank B to exchange $1700 for stellars= $1700*0.229042= 389.3714 stellars
From the above, we can see that Bank B has a better exchange rate as it is cheaper than Bank A(gives more stellar) . She should therefore use Bank B for her exchange.
jerry bought 5 candy bars for $14.75. if the king size candy bar cost $3.75 and a regular size candy bar cost $1.75, how much of each candy bar did he buy?
one equation looks like:
3.75x+1.75y=14.75
Answer:
King size(x): 3
Regular size(y): 2
Steps:
System of Equations:
x+y = 5
3.75x+1.75y = 14.75
Multiply 3.75 on all sides.
3.75x+3.75y = 18.75
3.75x+1.75y = 14.75
Subtract top and bottom
2y = 4
/2 /2
y = 2
After you know regular size amount, figure out king size ----3.
5-2 = 3.
