i. After how many weeks will Jennifer and William have the same amount of money in their bank accounts?
ii. How much will be in their accounts?
Answers
Answer:
5 weeks$100Step-by-step explanation:
Part iJennifer's account:
f(x) = 10x + 50William's account can be expressed as:
g(x) = 14x + 30Because the rate of change is 14 and y-intercept is 30
They will be same after x years, f(x) = g(x)
10x + 50 = 14x + 3014x - 10x = 50 - 304x = 20x = 5The accounts will be same after 5 weeks
Part iiThe amount in the accounts after 5 weeks:
f(5) = g(5) = 10*5 + 50 = $100Answer:
5 weeks
Step-by-step explanation:
Find the equation of willam's account:
1. find rate x1-x2
44-30 plug in
14 =rate 30=y-intercept starting valuse is always intercept
44+14=58 check
f(x)= 10x+50
f(x)= 14x+30 solve
10x+50=14x+30 set values together
20=4x subtract 10x and 30 from both sides
x=5

if the range of the function is restricted to 2 ≤ y ≤ 6, what is the domain?
Answers
Step-by-step explanation:
y = 0.5x + 4
When y = 2, x = -4. (shown in graph)
When y = 6, x = 4. (shown in graph)
Hence the domain would be -4 <= x <= 4.

Answer:

Step-by-step explanation:
note that
(a + b)² = a² + b² + 2ab , that is
a² + b² + 2ab = (a + b)² ← subtract 2ab from both sides
a² + b² = (a + b)² - 2ab
= 5² - 2(3)
= 25 - 6
= 19
Answer:
19
Step-by-step explanation:
since value of both a+b and a*b are given
formula for a^2 + b^2 is (a+b)^2-2*a*b
Substituting those value,
a^2+b^2=5^2-2*3
i.e. 25-6

The scale of a map is 1 clear : 13 km. Find the actual distance corresponding to the map distance. The distance on the map is 4.5 cm The actual distance is ___ km
Answers
Answer: The actual distance is 58.5 km.
Step-by-step explanation:
Given: Scale of map = 1 cm : 13 km
The distance on the map is 4.5 cm.
To find : The actual distance corresponding to the map distance.
The actual distance corresponding to the map distance =
( distance on the map) x ([tex]\dfrac{13}{1}[/tex])
[tex]=4.5\times13\\\\=58.5\ km[/tex]
Therefore , the actual distance is 58.5 km.

A new health drink has 150% of the recommended daily allowance (RDA) for a certain vitamin. The RDA for this vitamin is 50 mg. How many milligrams of the vitamin are in the drink? There are nothing mg of the vitamin in the drink.
Answers
Answer:
the number of milligrams of the vitamin in the drink is 75 mg
Step-by-step explanation:
The computation of the number of milligrams of the vitamin in the drink is as follows:
= RDA of the vitamin × given percentage ÷ percentage
= 50 mg × 150 ÷ 100
= 75 mg
hence, the number of milligrams of the vitamin in the drink is 75 mg
We simply applied the above formula so that the correct value could come

What is the slope of the line?
Answers
Answer:
-1
Step-by-step explanation:
Remember, slope is rise/run
Start from a point on the line and count up and over until you reach another point on the line.
For example, start from (0,-2), count up and left until you get to (-2,0). This gets you 2/2, which reduces to 1.
Since the line represents a negative slope, the slope is -1.

1. A system of linear equations is shown below as well as the first steps that Raffi is using to solve this system of linear equations by substitution. Choose the statement that best describes how Raffi is progressing toward a solution.
7x+y=4
3x−2y=3
Solution: Solve the first equation to obtain y=−7x+4. Substitute this into the second equation to get 3x−2⋅−7x+4=3.
2. Solve the following system by the substitution method.
2x−y=−4
−5x+3y=14
Answers
Answer:
The answer is below
Step-by-step explanation:
1) Below are the linear equations.
7x+y=4 (1)
3x−2y=3 (2)
The above linear equations are a system of equations. The substitution method is a technique for solving systems of linear equations.
Given that:
7x + y = 4
y = 4 - 7x
substitute y = 4 - 7x in equation 2, hence:
3x - 2(4 - 7x) = 3
3x - 8 + 14x = 3
17x = 3 + 8
17x = 11
x = 11/17
Put x = 11/17 in y = 4 - 7x
y = 4 - 7(11/17)
y = -9/17
2) 2x−y=−4 (1)
−5x+3y=14 (2)
From equation 1:
2x−y=−4
y = 2x + 4
Put y = 2x + 4 in equation 2:
-5x + 3(2x + 4) = 14
-5x + 6x + 12 = 14
x + 12 = 14
x = 2
Put x = 2 in y = 2x + 4:
y = 2(2) + 4
y = 8

If it takes 9 3/4 yards of material to make curtains for 3 windows, how much material is needed?
Answers
Answer:
3.25 yards of materials will be needed for 1 window
Answer:
3 1/4 (Verified) ✅Step-by-step explanation:
This is a rate problem, so we will write rate as a proportion and write the desired rate with x for the unknown value we need to find.
9.75/3 = x/1
Cross-mulitply
3x = 9.75
Divide by 3
x = 3.25 or 3 1/4
Another great thing with proportions is that we can check them to ensure we got the correct answer. All we do is substitute our determined value in for x
9.75/3 = 3.25/1
9.75 = 9.75 ✅
The answer of x = 3 1/4 is correct.
The largest ball of yarn ever created has a radius of 6 feet. It took 30 years to create.
Using 3.14 for pi which choice is the volume of the ball of yarn nearest hundred
87.85 cubic feet
150.72 cubic feet
834.68 square feet
904.32 cubic feet
Answers
Answer:
904.32 cubic ft
Step-by-step explanation:
To find the volume of a sphere, the formula is [tex]4\pi\frac{r^3}{3}[/tex]
First, 3.14 * 4 for 12.56.
The radius is 6, and that cubed is 216.
After that, divide 216 by 3 for 72
Then, 12.56 times 72, which gets you the final answer of 904.32 cubic ft.
(10 * 72) + (2 * 72) + (0.5 * 72) + (0.06 * 72)
720 + 144 = 864
864 + 36 = 900
900 + 4.32 = 904.32
