What is the solution of the equation?The solution of the equation means the value of the unknown or variable.
Kat has 19 coins, all quarters and dimes, that are worth a total of $4.
The system of equations that can be used to find the number of quarters, q, and the number of dimes, d, she has is shown.
q + d = 19
d = 19 – q ...1
0.25q + 0.1d = 4 ...2
Solve the equation, we have
0.25q + 0.1(19 – q) = 4
0.25q – 0.1q + 1.9 = 4
0.15q = 2.1
q = 14
Then the correct option is C.

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define systems
2x + 5y = 16
3x - 5y = -1
Step 2: Solve for x
Eliminate y (add equations): 5x = 15Divide 5 on both sides: x = 3Step 3: Solve for y
Define equation: 2x + 5y = 16Substitute in x: 2(3) + 5y = 16Multiply: 6 + 5y = 16Subtract 6 on both sides: 5y = 10Divide 5 on both sides: y = 2Answer:
(3, 2)
Step-by-step explanation:
2x + 5y = 16 ........ (1)
3x - 5y = - 1 ......... (2)
(1) + (2)
( 2x + 3x ) + [ 5y + ( - 5y)] = 16 + (- 1)
5x = 15 ⇒ x = 3
2(3) + 5y = 16 ⇒ y = 2

Answer:
We assign the older value to variable A and the newer value to variable B. Units, in this case the dollars, are always stripped or canceled out in percent change problems since we’re looking for increases or decreases in percentage.

What is an equation of the line that passes through the point (2,3) and is parallel to the line x+y=4
Answer:
The equation of required line is: [tex]\mathbf{x+y=5}[/tex]
Step-by-step explanation:
We need to find an equation of the line that passes through the point (2,3) and is parallel to the line x+y=4
For finding an equation of line, we need to find slope and y-intercept of the line.
Finding slope:
If the lines are parallel their slope is same
We are given: x+y=4
Writing in slope-intercept form: [tex]y=mx+b[/tex] where m is slope and b is y-intercept
[tex]x+y=4\\y=-x+4[/tex]
Comparing [tex]y=-x+4[/tex] with [tex]y=mx+b[/tex] the slope m is -1
So, slope of given line is -1
It is parallel with required line, so they have same slope.
The slope of required line is m=-1
Finding y-intercept
Using slope m=-1 and point(2,3) we can find y-intercept
Using slope-intercept form: [tex]y=mx+b[/tex]
[tex]y=mx+b\\3=-1(2)+b\\3=-2+b\\b=3+2\\b=5[/tex]
So, y-intercept is: b=5
The equation of required line having slope m=-1 and y-intercept b = 5 is
[tex]y=mx+b\\y=-1x+5\\y=-x+5\\x+y=5[/tex]
So, equation of required line is: [tex]\mathbf{x+y=5}[/tex]
The equation of the line that passes through the point (2,3) and is parallel to the line x+y=4 is y = -x + 5
Two equations are parallel if they have equal slope
For the equation x + y = 4
Rewrite the equation in the form y = mx + c
y = -x + 4
Compare y = -x + 4 with y = mx + c
The slope, m = -1
The equation parallel to x + y = 4 will also have a slope, m = -1
The line passes through the point (2, 3)
That is, x₁ = 2, y₁ = 3
The point-slope form of the equation of a line is:
y - y₁ = m(x - x₁)
Substitute x₁ = 2, y₁ = 3 into y - y₁ = m(x - x₁)
y - 3 = -1(x - 2)
y - 3 = -x + 2
y = -x + 2 + 3
y = -x + 5
The equation of the line that passes through the point (2,3) and is parallel to the line x+y=4 is y = -x + 5

Answer:
Step-by-step explanation:
Remark
The first step is the critical one. Take the base and raise it to x. Then take the log of the base and the number whose log you need. x (the power)is brought down and the logs divided.
2^x = 1024
log 2^x = log(1024)
x log(2) = log(1024)
x * 0.30102 = 3.0102
x = 30102/0.30102
x = 10
You could use the e system to solve this as well
2^x = 1024
ln(2^x) = ln(1024)
x * ln(2) = ln(1024)
x 0.6931 = 6.9315
x = 6.9315/0.69315
x = 9.999959
x = 10

Geometry! Find the length of a-b. Give answer in simplest radical form.
Answer:
Length of AB is [tex]\sqrt{106}[/tex]
Step-by-step explanation:
Let us use the rule of the distance To find the length of AB
∵ A = (9, -3)
∵ B = (0, 2)
∴ x1 = 9 and y1 = -3
∴ x2 = 0 and y2 = 2
∵ AB = [tex]\sqrt{(x2-x1)^{2}+(y2-y1)^{2}}[/tex]
→ Substitute the values of x1, x2, y1, and y2 in the rule to find AB
∴ AB = [tex]\sqrt{(0-9)^{2}+(2--3)^{2}}[/tex]
∴ AB = [tex]\sqrt{(-9)^{2}+(2+3)^{2}}[/tex]
∴ AB = [tex]\sqrt{81+(5)^{2}}[/tex]
∴ AB = [tex]\sqrt{81+25}[/tex]
∴ AB = [tex]\sqrt{106}[/tex]
→ The square root of 106 is the simplest radical form
∴ Length of AB is [tex]\sqrt{106}[/tex]

The following tables describe arithmetic sequences
(a) what is the common difference of the sequence xn?
(b) what is x8? what is x12?
(c) what is the common difference of the sequence am?
(d) what is a12? what is a15?
Answer:
a) the common difference is 20
b) [tex]x_8=115 , x_{12}=195[/tex]
c) the common difference is -13
d) [tex]a_{12}=52, a_{15}=13[/tex]
Step-by-step explanation:
a) what is the common difference of the sequence xn
Looking at the table, we get x_3=16, x_4=36 and x_5= 56
Deterring the common difference by subtracting x_4 from x_3 we get
36-16 =20
So, the common difference is 20
b) what is x_8? what is x_12
The formula used is: [tex]x_n=x_1+(n-1)d[/tex]
We know common difference d= 20, we need to find [tex]x_1[/tex]
Using [tex]x_3=16[/tex] we can find [tex]x_1[/tex]
[tex]x_n=x_1+(n-1)d\\x_3=x_1+(3-1)d\\15=x_1+2(20)\\15=x_1+40\\x_1=15-40\\x_1=-25[/tex]
So, We have [tex]x_1 = -25[/tex]
Now finding [tex]x_8[/tex]
[tex]x_n=x_1+(n-1)d\\x_8=x_1+(8-1)d\\x_8=-25+7(20)\\x_8=-25+140\\x_8=115[/tex]
So, [tex]\mathbf{x_8=115}[/tex]
Now finding [tex]x_{12}[/tex]
[tex]x_n=x_1+(n-1)d\\x_{12}=x_1+(12-1)d\\x_{12}=-25+11(20)\\x_{12}=-25+220\\x_{12}=195[/tex]
So, [tex]\mathbf{x_{12}=195}[/tex]
c) what is the common difference of the sequence [tex]a_m[/tex]
Looking at the table, we get a_7=104, a_8=91 and a_9= 78
Deterring the common difference by subtracting a_7 from a_8 we get
91-104 =-13
So, the common difference is -13
d) what is a_12? what is a_15?
The formula used is: [tex]a_n=a_1+(n-1)d[/tex]
We know common difference d= -13, we need to find [tex]a_1[/tex]
Using [tex]a_7=104[/tex] we can find [tex]x_1[/tex]
[tex]a_n=a_1+(n-1)d\\a_7=a_1+(7-1)d\\104=a_1+7(-13)\\104=a_1-91\\a_1=104+91\\a_1=195[/tex]
So, We have [tex]a_1 = 195[/tex]
Now finding [tex]a_{12}[/tex] , put n=12
[tex]a_n=a_1+(n-1)d\\a_{12}=a_1+(12-1)d\\a_{12}=195+11(-13)\\a_{12}=195-143\\a_{12}=52[/tex]
So, [tex]\mathbf{a_{12}=52}[/tex]
Now finding [tex]a_{15}[/tex] , put n=15
[tex]a_n=a_1+(n-1)d\\a_{15}=a_1+(15-1)d\\a_{15}=195+14(-13)\\a_{15}=195-182\\a_{15}=13[/tex]
So, [tex]\mathbf{a_{15}=13}[/tex]
