Find the sum of
(9c+8)+(5x-2)+(3y+7)
Answer:
9c + 5x + 3y + 13
Step-by-step explanation:
you can't combine any of the numbers wwith variables because the variables aren't the same but you can combine the other numbers (8, -2, 7)
8 - 2 = 6
6 + 7 = 13
put the equation back together but instead replace the 8, -2, and 7 with 13 giving you
9c + 5x + 3y +13
2/4 notes equal to how many eighth notes
Answer:
Two eighth notes equal one quater note in duration.
Step-by-step explanation:
9514 1404 393
Answer:
4/8
Step-by-step explanation:
Multiply numerator and denominator by the same value to find the equivalent fraction. You know that 2×4 = 8, so the desired value is ...
[tex]\dfrac{2}{4}=\dfrac{2}{4}\times\dfrac{2}{2}=\dfrac{2\times 2}{4\times 2}=\dfrac{4}{8}[/tex]
2 quarter-notes equal 4 eighth notes.

solve for x and Y will give brainliest
Answer:
x = - 5, y = - 9
Step-by-step explanation:
Given
x + 9i = - 5 - yi
For the 2 sides to be equal then the coefficients of like terms must be equal.
x = - 5 and 9 = - y ⇒ y = - 9
Answer:
X= Subtract 9 i from both sides of the equation.
Y= Isolate the variable by dividing each side by factors that don't contain the variable.
Answer:
x = − 5 − y i − 9 i
y = x i − 9 + 5 i
AB is a line of symmetry of this arrow shape. A)Calculate The Perimeter of the shape.
B) The Value of H
C) The area of the shape
Answer:
A)58cm
B)[tex]h=4\sqrt{5}cm[/tex]
C)125.55square cm
Step-by-step explanation:
AB is a line is symmetry
Total length of left half part=12cm+9cm+3cm+5cm
Total length of left half part=29 cm
Length of left half part=Length of right half part
Therefore, length of right half part=29 cm
A) Perimeter of the shape=29cm+29cm=58cm
B)
Pythagoras theorem
[tex](Hypotenuse)^2=(Base)^2+(Perpendicular\;side)^2[/tex]
Hypotenuse=12 cm
Base=5+3=8cm
In triangle ADC
Now, using Pythagoras theorem
[tex](12)^2=8^2+h^2[/tex]
[tex]144=64+h^2[/tex]
[tex]h^2=144-64=80[/tex]
[tex]h=\sqrt{80}=4\sqrt{5}cm[/tex]
C)
Area of shape=Area of triangle+ area of rectangle
Area of shape=[tex]\frac{1}{2}\times b\times h+l\times b[/tex]
Where l=9cm
breadth=3+3=6cm
h=[tex]4\sqt{5}cm[/tex]
base=2(5)+3(2)=16cm
Area of shape=[tex]\frac{1}{2}\times\times 16\times 4\sqrt{5}+9\times 6[/tex]
Area of shape=125.55 square cm
A bakery needs to make 4 batches of bagels before opening in 3 hours. Each batch of bagels takes 2/4 of an hour to make. How many bagel batches can the bakery make before they open
Answer:6
Step-by-step explanation:
Since each batch of bagels takes 2/4 of an hour to make. This means that in one hour, 2 batches would be made.
Therefore, in 3 hours, the number of batches that would be made will then be:
= 2 × 3
= 6
Therefore 6 batches can be made before opening
Lina spent 1/3 of her money. She now has $20 left. How much money did she have originally
P.s it is not 60
Answer:
$30
Step-by-step explanation:
3/3 - 1/3 = 2/3
The fraction shows how much she has left.
2/3 = $20
1/3 = $20 ÷ 2 = $10
3/3 = $10 x 3 = $30

Which polynomial function f(x) has a leading coefficient of 1, roots –4, 2, and 9 with multiplicity 1, and root –5 with multiplicity 3?
Answer:
f(x) = (x + 5)(x + 5)(x + 5)(x + 4)(x - 2)(x - 9)
Step-by-step explanation:
The polynomial function f(x) possessing a key coefficient of 1:
[tex](x+4)(x-2)(x-9)(x+5)^{3}[/tex] = 0
By opening the above equation;
f(x) = (x + 5)(x + 5)(x + 5)(x + 4)(x - 2)(x - 9)
∵ Thus, the above polynomial function makes the coefficient 1 with a multiplicity of 3 for root - 5 and 1 for -4, 2, and 9.
Answer:

Is (1, 1) a solution to this system of equations?
8x + 2y = 10
X + 9y = 10
Answer:
Yes.
Step-by-step explanation:
[tex]8x + 2y = 10 \\ x + 9y =10 \\ x = 10 - 9y \\ 8(10 - 9y) + 2y = 10 \\ 80 - 72y + 2y = 10 \\ - 70 y = - 70 \\ y = 1 \\ x = 10 - 9y[/tex]
[tex]x = 10 - 9 \times 1 \\ x = 1[/tex]

a triangle has base 2x+1 and height 6x-3. What value of x would give an area of 240m2?
Answer:
The values of x which would give an area of 240m² would be:
[tex]x=-\frac{\sqrt{161}}{2},\:x=\frac{\sqrt{161}}{2}[/tex]
Step-by-step explanation:
Given
The base of triangle b = 2x+1
The height of triangle h = 6x-3
The Area of the triangle A = 240 m²
The Area of the triangle has the formula
A = 1/2 × b × h
substituting b = 2x+1, h = 6x-3 and A = 240
[tex]240\:=\:\frac{1}{2}\:\left(2x+1\right)\:\times \left(6x-3\right)[/tex]
[tex]480=\left(2x+1\right)\left(6x-3\right)[/tex]
[tex]480=12x^2-3[/tex]
Subtract 480 from both sides
[tex]12x^2-3-480=480-480[/tex]
[tex]12x^2-483=0[/tex]
[tex]3\left(4x^2-161\right)=0[/tex]
[tex]3\left(2x+\sqrt{161}\right)\left(2x-\sqrt{161}\right)=0[/tex]
Using the zero factor principle
if ab=0, then a=0 or b=0 (or both a=0 and b=0)
[tex]2x+\sqrt{161}=0\quad \mathrm{or}\quad \:2x-\sqrt{161}=0[/tex]
solving
[tex]2x+\sqrt{161}=0[/tex]
[tex]2x=-\sqrt{161}[/tex]
Divide both sides by 2
[tex]\frac{2x}{2}=\frac{-\sqrt{161}}{2}[/tex]
[tex]x=-\frac{\sqrt{161}}{2}[/tex]
also solving
[tex]2x-\sqrt{161}=0[/tex]
[tex]2x=\sqrt{161}[/tex]
Divide both sides by 2
[tex]\frac{2x}{2}=\frac{\sqrt{161}}{2}[/tex]
[tex]x=\frac{\sqrt{161}}{2}[/tex]
Therefore, the values of x which would give an area of 240m² would be:
[tex]x=-\frac{\sqrt{161}}{2},\:x=\frac{\sqrt{161}}{2}[/tex]

The table shows values for functions f(x) and g(x)
What is the solution to f(x)=g(x)
Select each correct answer
X= -3
X= -2
X=-1
X=0
X=1
X=2
X=3
Answer:
we conclude that at x = -2 and x = -1, the value of f(x) = 2⁻ˣ and g(x) = -2x is the same.
Therefore, the solution to f(x) = g(x) is:
x = -2
x = -1
Step-by-step explanation:
Given the table
x f(x) = 2⁻ˣ g(x) = -2x
-3 8 6
-2 4 4
-1 2 2
0 1 0
1 1/2 -2
2 1/4 -4
3 1/8 -6
If we carefully observe, we can determine that
at x = -2, the value of f(x) = 2⁻ˣ and g(x) = -2x is the same.
In other words,
at x = -2
f(-2) = 4 g(-2) = 4Thus,
at x = -2
f(x) = g(x)
Also at x = -1, the value of f(x) = 2⁻ˣ and g(x) = -2x is the same.
In other words,
at x = -1
f(-1) = 2 g(-1) = 2Thus,
at x = -1
f(x) = g(x)
Summary:
Thus, we conclude that at x = -2 and x = -1, the value of f(x) = 2⁻ˣ and g(x) = -2x is the same.
Therefore, the solution to f(x) = g(x) is:
x = -2
x = -1
The height of a vase is 45.7 centimeters when rounded to the nearest tenth of a centimeter. What is the shortest possible height of the vase? Give your answer to 3 decimal places.
Answer:
45.650 centimeters
Step-by-step explanation:
The height of a vase is 45.7 centimeters when rounded to the nearest tenth of a centimeter. What is the shortest possible height of the vase? Give your answer to 3 decimal places
Given that :
Height of vase = 45.7 when rounded to the nearest tenth
The shortest possible height of the vase : will be 45.65, this is because, the subsequent digit (hundredth) after the tenth digit is the figure rounded to give a tenth digit of 7
From the we know that the tenth digit before rounding is 7 - 1 = 6
And smallest possible value the hundredth placed digit could have in other to be rounded to 1 is 5.
To three decimal place, the thousandth placed value could take the least possible value in a digit series, which is 0
Hence, the shortest possible height of the vase = 4.650

Which expression is equivalent to 4 x 4 x 4 x 5 x 5 ?
Answer:
4³×5² or 4³5²
Step-by-step explanation:
This is because there are three consecutive 4s, so you have to put the 4 into exponential form 3 times. So the exponential form for the 4s will be 4³. There are also 2 consecutive 5s so you have to include 2 in the exponential form. So, the exponential form of the 5s is 5². Now you have to somehow multiply them together. You could do this by putting a multiplication sign, (4³×5²) or you could bunch them together and it will mean the same thing (4³5²).
Hope this helps :)

Identify the correct slope and the y-intercept of
3x - 2y = 12
Answer:
The answer is C
Step-by-step explanation:
3x-2y=12
-3x -3x
-2y=-3x+12
y=3/2x-6
slope = 3/2
y-intercept = -6
Answer:
C) m=3/2 and b=-6
Step-by-step explanation:
The easiest way to do this is by converting the equation into slope-intercept form, which is written y=mx+b. So...
3x-2y=12 Subtract 3x from both sides.
-3x -3x
-2y=-3x+12 Divide both sides by -2.
/-2 /-2
y=3/2x-6
The slope (m) is always right next to x, which, in this case, is 3/2.
The y-intercept (b) is the (simplified) regular number in the equation.
So, the correct answer is C) m=3/2 and b=-6.
Hope this helps you out! Have a nice day :3
