Answer:
b. x - 2y = 4
Step-by-step explanation:
The two points on the graph are (0, -2) and (4, 0).
Find slope:
m = (y₂ - y₁) / (x₂ - x₁)
= (0 - (-2)) / (4 - 0)
= 2 / 4
= 1 / 2
Find y intercept using anyone of the points above:
y = mx + b
-2 = 1/2(0) + b
b = -2
Use m and b to make equation of line:
y = mx + b
y = 1/2x - 2
Possible answers:
a. 4x - 2y = 4
-2y = -4x + 4
y = 2x - 2
b. x - 2y = 4
-2y = -x + 4
y = 1/2x - 2
c. -2x + 4y = -4
4y = + 2x - 4
y = 1/2x - 1
Only choice b equals the equation of line above.

Brody invested $220 in an account paying an interest rate of 3.6% compounded
annually. Assuming no deposits or withdrawals are made, how much money, to the
nearest ten dollars, would be in the account after 17 years?
Answer:
400
Step-by-step explanation:
Delta
The amount after 17 years is $400
How to determine the amount after 17 years?The given parameters are:
Principal, P = $220Rate, r = 3.6%Time, t = 17 yearsThe interest rate is compounded annually;
So, the amount after t years is:
A = P *(1 + r)^t
This gives
A = 220 * (1 + 3.6%)^17
Evaluate
A = 401.36
To the nearest ten dollars, we have:
A = 400
Hence, the amount after 17 years is $400

Kyla alternates between walking and jogging on an 11-mile trail. Her walking speed is 4 mi/h, and her jogging speed is 6 mi/h. Kyla takes 2 hours to go from the beginning to the end of the trail. Write and solve an equation to find the distance Kyla walked and the distance she jogged.
Answer:
Kyla walked 2 miles and jogged 9 miles
Step-by-step explanation:
Let the distance Kyla walked be x
and the distance Kyla jogged be y
Since the trail is 11-mile long, then
x + y = 11
Now, from the question,
Her walking speed is 4 mi/h and her jogging speed is 6 mi/h
Let the time spent to walk be t₁ and the time spent to jog be t₂
From
Distance = Speed × Time
Then, the distance walked x is
x = 4 mi/h × t₁
and the distance jogged y is
y = 6 mi/h × t₂
From the question, Kyla takes 2 hours to go from the beginning to the end of the trail, that is
t₁ + t₂ = 2 hours
∴t₁ = 2 - t₂
Since
x + y = 11, then we can write that
(4 mi/h × t₁) + (6 mi/h × t₂) = 11
But t₁ = 2 - t₂
Then,
(4 mi/h × t₁) + (6 mi/h × t₂) = 11; becomes
(4 mi/h × (2 - t₂)) + (6 mi/h × t₂) = 11
8 - 4t₂ + 6t₂ = 11
2t₂ = 11 - 8
2t₂ = 3
t₂ = 3/2
t₂ = 1.5 hours
This is the time spent to jog
Then, from t₁ = 2 - t₂
t₁ = 2 - 1.5
t₁ = 0.5 hour
This is the time spent to walk
Now, For the distance Kyla walked, x
x = 4 mi/h × t₁
x = 4 mi/h × 0.5
x = 2 miles
Hence, she walked 2 miles
and for the distance Kyla jogged, y
y = 6 mi/h × t₂
y = 6 mi/h × 1.5
y = 9 miles
Hence, she jogged 9 miles

Rembrandt framed his masterpiece. The painting by itself is a rectangle with length 20 \text{ cm}20 cm 20, start text, space, c, m, end text and width 16 \text{ cm}16 cm 16, start text, space, c, m, end text. The painting and frame together form a larger rectangle with length 25 \text{ cm}25 cm 25, start text, space, c, m, end text and width 20 \text{ cm}20 cm 20, start text, space, c, m, end text. Find the area of the frame.
Answer:
180cm²
Step-by-step explanation:
Area of the frame = area of the frame+ painting - area of painting.
Area of a rectangle = Length × Width
Area of the painting = 20cm×16cm
Area of the painting = 320cm²
Area of the paint+ frame = 25cm×20cm
Area of the paint+ frame = 500cm²
Area of the frame = 500cm²-320cm²
Area of the frame = 180cm²
Hence the area of the frame is 180cm²

Alan purchased 16 shares of company stock for $390.40. A month later, the total value of his shares fell to $291.20. What is the current price per share if each share costs the same?
A.
$6.20
B.
$18.20
C.
$24.04
D.
$24.40
Answer: $18.20
Step-by-step explanation:
390.40/16 to find the initial costs of the shares. That would be $24.40 per share. However, since the stock has fallen, you would do that same division, but with the new value. 291.20/16, which is $18.20
Answer:
$18.20 per share is the value of each stock currently
Step-by-step explanation:
Take the value the stocks are worth now and divide by the number of shares
291.20/16
$18.20 per share
$18.20 per share is the value of each stock currently

A function assigns the value of each element of one set to the other specific element of another set. The value of f(8) is 5.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
The function that is given is mentioned below. Now, the value of the function can be found as shown below.
A.) f(-10)=?
When the value x is -10, it will lie in the first category of the function, therefore, the function for this value of x will be,
[tex]f(x) = 2x+1\\\\f(-10) = 2(-10)+1\\\\f(-10) = -20+1 = -19[/tex]
B.) f(2) = ?
When the value x is 2, it will lie in the second category of the function, therefore, the function for this value of x will be,
[tex]f(x) = x^2\\\\f(2) = 2^2 = 4[/tex]
C.) f(-5)=?
When the value x is -5, it will lie in the first category of the function, therefore, the function for this value of x will be,
[tex]f(x) = 2x+1\\\\f(-5) = 2(-5)+1\\\\f(-5) = -10+1 = -9[/tex]
D.) f(-1)=?
When the value x is -1, it will lie in the second category of the function, therefore, the function for this value of x will be,
[tex]f(x) = x^2\\\\f(-1) = (-1)^2 = 1[/tex]
E.) f(8)=?
When the value x is 8, it will lie in the third category of the function, therefore, the function for this value of x will be,
[tex]f(x) = x-3\\\\f(8) = 8-3 = 5[/tex]
