Step-by-step explanation:
is 9x=63,x=7 true or false
Answer:
True
9 * 7 = 63
Therefore when x=7 9x=63
The equation given is true since 7 is the solution.
What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign.
The two sides of an equation is usually called as left hand side and right hand side.
The given equation is 9x = 63.
There is only one variable here, x.
We have to solve this equation and find whether the solution is 7 or not.
Solution of the equation is the value of x.
9x = 63
Divide both sides of the equation by 9, then, we get,
9x / 9 = 63 / 9
9 gets cancelled in the left hand side and 63/9 = 7.
So we get,
x = 7
So the given statement is true that for 9x = 63, the solution is x = 7.
Hence the given equation is true.

Ryan invested $5000 in an account that averaged 5% growth per year. Which equation would be used to best model the situation?
Answer:
f(x)=5000(1+0.05)^x
Step-by-step explanation:
Use the formula: f(x)=P(1+b)^x
P is principal or y-intercept. 5000 is principal.
b is the percentage in decimal form. 0.05 is b.
x is time, in this case years. Since there is not a certain number of years leave x as x.
f(x)=5000(1+0.05)^x
Hope this helps!

When 3 times a number is subtracted from 45 the result is 5 plus the number. what is the number?
Answer:
n = 10
Step-by-step explanation:
let the number be n , then
45 - 3n = n + 5 ( subtract n from both sides )
45 - 4n = 5 ( subtract 45 from both sides )
- 4n = - 40 ( divide both sides by - 4 )
n = 10

Solve for x......
[tex]4x + 10 = 2x + 26[/tex]
Answer:
x=8
Step-by-step explanation:
4x+10 = 2x+26
4x-2x+10=2x-2x+26 [Subtract 2x from both sides]
2x+10=26
2x + 10 - 10 = 26 - 10 [Subtract 10 from both sides]
2x = 1
2x/2 = 16/2 [Divide both sides by 2]
x = 8
CHECK:
Does 4x+10 = 2x+26 when x is 8?
4(8)+10 = 2*(8)+26 ?
32+10 = 16+26 ?
42 = 42 YES
Answer:
[tex]\large \boxed{\sf x =8}[/tex]
Explanation:
[tex]\sf \rightarrow 4x + 10 = 2x + 26[/tex]
collect like terms
[tex]\sf \rightarrow 4x -2x = 26-10[/tex]
subtract like terms
[tex]\sf \rightarrow 2x = 16[/tex]
divide both sides by 2

Sarah’s company sells bracelets and rings. Her first customer buys 3 bracelets and 10 rings, spending a total of $48. Her second customer buys 7 bracelets and 4 rings, spending a total of $54. How much does Sarah charge for one bracelet?
Please select the best answer from the choices provided
A. $3.00
B. $6.00
C. $12.00
D. not enough information
Sarah charges $6.00 for one bracelet.
We know that a collection of one or more linear equations containing the same variables is known as a system of linear equations in mathematics.
Let Sarah charges $x and $y for one bracelet and one ring respectively.
Since her first customer spends $48 on 3 bracelets and 10 rings, we can write it as
3x + 10y = 48 ...(1)
Since her second customer spends $54 on 7 bracelets and 4 rings, we can write it as
7x + 4y = 54 ...(2)
Now, we have to solve this system of linear equations.
Multiplying (1) by 2, 6x + 20y = 96 ...(3)
Multiplying (2) by 5, 35x + 20y = 270 ...(4)
Subtracting (3) from (4), 35x + 20y - 6x - 20y = 270 - 96
i.e. 29x = 174
i.e. x = 174/29 = 6
Therefore we can conclude that Sarah charges $6 for one bracelet. Option B is correct.

A circle has a diameter with endpoints (-7, 1) and (-3, 7).
What is the equation of the circle?
r2 = ( x - 3) 2 + ( y + 4) 2
r2 = ( x + 3) 2 + ( y - 4) 2
r2 = ( x + 5) 2 + ( y - 4) 2
r2 = ( x - 5) 2 + ( y + 4) 2
Answer: (C) r² = (x+5)²+(y-4)²
Solution:-
The given endpoints are (-7,1) and (-3,7)
so the center will be at the mid point of the line connecting these two points.
hence, center ={ (-7+-3)/2, (1+7)/2 }
hence, C= (-5,4)
so, the equation of the circle is:-
⇒ (x-(-5))²+(y-4)²=r²
or, (x+5)²+(y-4)²=r²

Answer:
missing side lengths are
leg 1 is 4√2
leg 2 is 4√2
hypotenuse is 8
Step-by-step explanation:
leg 1 is y
leg 2 is 4√2
45-45-90 right triangle means
legs are equal
the longest side is the hypotenuse which is
x
pythagorean theorem =
a² + b² = c²
a and b are the legs
c is hypotenuse
(4√2)² + (4√2)² = c²
4√2 = √16*2 = √32
(√32)² + (√32)² = c²
32 + 32 = c²
64 = c²
take the square root of both sides
√64 = √c²
8 = c
c = 8

Describe three ways to determine the measure of segment YZ.
Triangle X Y Z is shown. Angle X Y Z is a right angle and angle Z X Y is 30 degrees. The length of hypotenuse X Z is 50 meters.
Step-by-step explanation:
tan 30 degre = perpendicular /base
I wrote the rule than you can easily find hope this help you
Using 3 different methods, we can find that YZ = 25m
The complete image of a triangle is attached with the answer below.
What is trigonometry?The branch of mathematics sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.
For a given triangle rectangle with a known angle θ and a hypotenuse H, we can write the trigonometric relations
sin(θ) = (opposite cathetus)/H
cos(θ) =(adjacent cathetus)/H
tan(θ) =(opposite cathetus)/(adjacent cathetus)
Now, in the given image we can see that:
θ = 30°
H = 50m
XY = adjacent cathetus
YZ = opposite cathetus.
We want to find YZ, so with the known things, we can use the first relation:
Sin 30 = YZ / 50
YZ = 50 x Sin30 = 25 meters
Now let's try another way.
We know that the sum of the internal angles of a triangle is always equal to 180°
In a triangle rectangle, we always have an angle equal to 90°.
Then the missing angle for our triangle can be computed from:
Z + 90° + 30° = 180°
Z = 180° - 90° - 30° = 60°
From this angle, the side YZ is the adjacent cathetus, then we can use the second trigonometric relation:
Cos 60 = YZ / 50
YZ = 50 x Cos 60 = 25 meters
Third way.
Whit the same angle we could find the side XY, the opposite cathetus, with:
Sin 60 = XY / 50
XY = 50Sin 60 = 43.3 meters
Now that we know one of the catheti, we can use the last trigonometric relation
tan 60 = XZ / YZ = 43.3 / YZ
YZ = 43.3 / tan 60 = 25 meters
