Answer:
-19
Step-by-step explanation:
ok so since they give you all the variables you can substitute their values
for example instead of 3xy you can write 3*(-4)y
so that is the basic idea for this problem
after substituting, the new equation is 3*(-4)*2 +5
i plan on using order of operations, or PEMDAS
3*(-4)=(-12)
(-12)*2=(-24)
-24+5=-19
so the answer is -19
hope this helps!

1. A bag has 16 marbles in it: 6 red, 4 blue, 3 yellow, and 3 green. A marble is drawn and put back, and then another marble is drawn. What is the probability that a blue marble was drawn followed by a yellow marble?
2. A bag has 16 marbles in it: 6 red, 4 blue, 3 yellow, and 3 green. A marble is drawn and not put back, and then another marble is drawn. What is the probability that a blue marble was drawn followed by a yellow marble?
Thank you.
Answer:
1. 0.0469 (4.d.p)
2. 0.05
Step-by-step explanation:
1. First we'll find the probability of drawing a blue marble.
P = (No. favourable events)/(Total events)
In this case it's:
P = (No. blue marbles)/(Total Marbles)
Therefore P(Blue) = 4/16 = 0.25
Now we find the probability of drawing a yellow marble:
The total number will be the same because the blue marble will have been put back.
P(Yellow) = 3/16 = 0.1875
Now, since we are calculating the probability of both happening we multiply together the two individual probabilities to get the combined probability of both:
0.25 x 0.1875 = 0.0469 (4.d.p)
2. The probability of drawing a blue marble is still the same so we can keep that: P(Blue) = 0.25
But this time, the marble is not replaced. This means that the total number of marbles has changed when drawing the yellow marble:
P(Yellow) = 3/15 = 0.2
Now we multiply them together again to find the combined probability of both happening:
0.25 x 0.2 = 0.05

A person invested $2,500 in an account growing at a rate allowing the money to
doubleevery 11 years. How long, to the nearest tenth of a year would it take for the
value of the account to reach $3,800?
Answer:
Step-by-step explanation:
A person invested $2,500 in an account growing at a rate allowing the money to double every 11 years. How long, to the nearest tenth of a year would it take for the
value of the account to reach $3,800?
The formula for exponential growth given as:
A(t) = Ao (1/2)^t/t½
A(t) = Amount after time t = $3,800
Ao = Initial amount invested = $2500
t = Time in years
t½ = Time it takes to double = 11 years
Hence,
3800 = 2500(1/2)^t/11
Divide both sides by 2500
3800/2500 = 2500(1/2)^t/11/2500

Pete bought a house in 2009 for $200,000.
The value of his house increased by 10%
annually.
Answer:
Value of house in 2021 = $627,680 (Approx.)
Step-by-step explanation:
Given:
Value of house in 2009 = $200,000
Rate increased per year = 10% annually
Find;
Value of house in 2021
Computation:
Number of year = 2021-2009 = 12 year
Value of house in 2021 = Value of house in 2009[1+Rate increased per year]ⁿ
Value of house in 2021 = 200,000[1+10%]¹²
Value of house in 2021 = 200,000[1+0.1]¹²
Value of house in 2021 = 200,000[1.1]¹²
Value of house in 2021 = 200,000[3.1384]
Value of house in 2021 = $627,680 (Approx.)

Find the two stationary points
on the graph of y=x4 - 4x3
Answer: [tex](0,0), (3,-27)[/tex]
Step-by-step explanation:
Given
Curve is [tex]y=x^4-4x^3[/tex]
The stationary point on a differentiable function is the points where the differentiation of the function is zero i.e. slope is zero at that point.
Differentiate the curve [tex]f(x)=x^4-4x^3[/tex]
[tex]\Rightarrow f'(x)=4x^3-12x^2[/tex]
Equate it to zero
[tex]\Rightarrow 4x^3-12x^2=0\\\Rightarrow 4x^2(x-3)=0\\\Rightarrow x=0,0,3[/tex]
Put [tex]x=0,3[/tex] in the function [tex]f(x)=x^4-4x^3[/tex]
[tex]\Rightarrow f(0)=0\\\Rightarrow f(3)=3^4-4(3)^3\\\Rightarrow f(3)=81-108\\\Rightarrow f(3)=-27[/tex]
Therefore, the stationary points are [tex](0,0), (3,-27)[/tex]

Answer:
D. 17
Step-by-step explanation:
1. Set up an equation (2x + 5) + (3x + 10) = 100
2. 2x + 3x= 5x and 5 + 10 = 15
3. The equation simplified 5x + 15 = 100
4. Move the 15 to the other side of the equation. 5x = 100 - 15
5. 5x = 85
6. Finally, divide 85/5
7. Our final answer is 17.
I WILL GIVE BRAINLIEST!! I really need help with this question.
Answer:
x = 70°, y = 110° , z = 85°
Step-by-step explanation:
∠ BEA and ∠ CDA are corresponding angles and congruent , then
x = 70°
x and y are adjacent angles and sum to 180°
x + y = 180°
70° + y = 180° ( subtract 70° from both sides )
y = 110°
∠ ABE and ∠ ACD are corresponding angles and congruent , then
z = 85°

Find the coordinates of point M, that partitions the directed line segment SY from S(4,2) to Y(-4,-6) in a ratio of 1/3.
Answer:
the coordinates of point M = (2,0)
Step-by-step explanation:
Given;
point S along the segment, = S(4,2)
point Y along the segment, = Y(-4, -6)
ratio of the partition = ¹/₃
total ratio = 1 + 3 = 4
The midpoint of segment SY is calculated as follows;
[tex]mid-point (o) = \frac{x_1 + x_2}{2} ,\ \frac{y_1 + y_2}{2}\\\\ mid-point (o) = \frac{4 + (-4)}{2} , \ \frac{2+ (-6)}{y} \\\\mid-point (o) = \frac{0}{2} , \ \frac{-4}{2} \\\\mid-point (o) = (0, \ -2)[/tex]
The coordinates of point M is calculated as follows;
point M divides the segment into 4 equal parts with point O as the mid-point.
M
S--------------|-------------------O-------------------|-------------------Y
|SO| = |OY|
[tex]The \ mid-point \ of \ SO = M\\\\Point \ S = (4,2) \\\\Point \ O = (0,-2) \\\\Point \ M = \frac{4 + 0}{2}, \frac{2 - 2}{2} \\\\ Point \ M = 2, 0 \\\\M = (2,0)[/tex]
Therefore, the coordinates of point M = (2,0)
Two numbers have these properties Both numbers are greater than 8 The HCF is 8 The LCM is 80 Find the two numbers
Answer:
10 and 64.
16 and 40
Step-by-step explanation:
The product of the two numbers is equal to the product of LCM and HCF
Number 1* Number 2= LCM * HCF
Number 1* Number 2= 8*80
Number 1* Number 2= 640
Both the numbers are greater than 8. Suppose one number is 10 then the other number will be 640 ÷ 10= 64
so the two numbers will be 10 and 64.
Similalrly the two numbers can also be 16 and 40 and like wise.
Any number greater than 8 dividing 640 will give the second number also.

There are 6 children on a bus. Each child is wearing a hat. What fraction of the children on the bus are wearing a hat?
Answer:
6/6
Step-by-step explanation:
if there are 6 children, and each of them are wearing a hat, that means there are six children wearing hats, out of the six children on the bus. so the answer would be 6/6.
All 6 childrens in the bus are wearing a hat.
What is algebraic expression?An algebraic expression in mathematics is a combination of terms both constant and variable. For example, we can write the algebraic expressions as -
2x + 3y + 5
2z + y
x + 3y
Given is that there are 6 children on a bus. Each child is wearing a hat.
Total number of children in the bus = 6
Number of children wearing a hat = 6
Fraction of children wearing a hat -
n = (Number of children wearing a hat/Total number of children in the bus)
n = 6/6
n = 1
Therefore, all 6 childrens in the bus are wearing a hat.

Use the two yellow points to write the equation in slope-intercept form. Write any coefficients as integers, proper fractions, or improper fractions in simplest form.
Answer:
y = 7/5x - 21/5
Step-by-step explanation:
points to use to find slope: (3,0) and (8,7)
slope = 7-0 / 8-3
slope = 7/5
find y-intercept (or 'b')
0 = 3(7/5) + b

11. A rectangle has a diagonal of length 10 units and one side of length 6 units.
How many units long is the perimeter of the rectangle?
The required perimeter of the rectangle is 28 units.
The rectangle is 4 sided geometric shape whose opposites are equal in lengths and all angles are about 90°.
Here,
Let's denote the length of the rectangle as L and the width as W. We know that the diagonal of the rectangle has a length of 10 units, and we can use the Pythagorean theorem to relate the length, width, and diagonal,
L² + W² = diagonal² [= 10² = 100]
We also know that one side of the rectangle has a length of 6 units, which we can assume is the width W. Therefore, we can solve for the length L,
L² + 6² = 100
L² = 100 - 36
L² = 64
L = 8
So the length of the rectangle is 8 units.
To find the perimeter of the rectangle, we can use the formula P = 2L + 2W, where L is the length and W is the width:
P = 2(8) + 2(6)
P = 16 + 12
P = 28
Therefore, the perimeter of the rectangle is 28 units.
