From the triangle given, we are required to solve for x and y.
Since they are similar triangles, let's find x and y below.
For x:
[tex]\frac{5}{8}=\frac{5+x}{10}[/tex]Let's find x, from the equation above.
Cross multiply:
[tex]\begin{gathered} 8(5+x)=10(5) \\ \\ 40+8x=50 \\ \\ \text{Subtract 40 from both sides:} \\ 40-40+8x=50-40 \\ \\ 8x=10 \end{gathered}[/tex]Divide both sides by 8:
[tex]\begin{gathered} \frac{8x}{8}=\frac{10}{8} \\ \\ x=1.25 \end{gathered}[/tex]For y:
[tex]\begin{gathered} \frac{7}{8}=\frac{7+y}{10} \\ \\ 8(7+y)=7(10) \\ \\ 56+8y=70 \\ \\ 8y=70-56 \\ \\ 8y=14 \\ \\ \frac{8y}{8}=\frac{14}{8} \\ \\ y=1.75 \end{gathered}[/tex]ANSWER:

The height of a triangle is 5 centimeters greater than the base. The area of the triangle is 63 square centimeters. Find the length of the base and the height of the triangle.
The base and height of the triangle are 9 cm and 14 cm respectively.
How to find the side of a triangle?The height of the triangle is 5 centimetres greater than the base.
The area of the triangle is 63 cm².
Therefore,
area of a triangle = 1 / 2 bh
where
b = baseh = heightTherefore,
h = 5 + b
Hence,
area of a triangle = 1 / 2 × b × (5 + b)
area of a triangle = 1 / 2 × 5b + b²
63 = 5b + b² / 2
cross multiply
126 = 5b + b²
b² + 5b - 126 = 0
b² + 14b - 9b - 126 = 0
b(b + 14) - 9(b + 14) = 0
(b + 14)(b - 9) = 0
b = -14 or b = 9
Therefore, the base can only be positive .
Hence,
Base of the triangle = 9 cm
height of the triangle = 9 + 5 = 14 cm

Anders discovered an old pay statement from 12 years ago. His monthly salary at the time was $2800 versus his current salary of $4970 per month. At what (equivalent) compound annual rate has his salary grown during the period
The (equivalent) compound annual rate at which Anders' salary has grown during the 12 years is 4.9%.
What does the compound annual rate signify?The compound annual rate is the equivalent rate of interest at which the present value of money grows to attain a future value.
At a 4.9% compound annual rate, Anders' salary has been growing by adding the growth amount to the initial salary and compounding both the principal and subsequent interest amounts until 12 years.
N (# of periods) = 12 years
PV (Present Value) = $2,800
PMT (Periodic Payment) = $0
FV = $-4,971.23
Results:
I/Y (Interest per year) = 4.9%
Total Interest = $2,171.23
Thus, using the online finance calculator, we can determine that Anders' salary has been compounded at 4.9% annually.

An equation of the quadratic function in standard form is equal to -2x² - 7x - 6 = 0.
What is a quadratic function?A quadratic function can be defined as a mathematical expression (equation) that can be used to define and represent the relationship that exists between two or more variable on a graph.
In Mathematics, the standard form of a quadratic equation is given by;
ax² + bx + c = 0
y = f(x) = ax² + bx + c
Next, we would formulate a system of equations from the data contained in the table above:
-6 = a(-3)² + b(-3) + c ⇒ -6 = 9a - 3b + c .......equation 1.
0 = a(-2)² + b(-2) + c ⇒ 0 = 4a - 2b + c .......equation 2.
-2 = a(-1)² + b(-1) + c ⇒ -2 = a - b + c .......equation 3.
From eqn. 2, we have:
c = -4a + 2b .....equation 4.
Substituting eqn. 4 into eqn. 1 and 3, we have:
-2 = a - b - 4a + 2b ⇒ -2 = -3a + b
-6 = 9a - 3b - 4a + 2b ⇒ -6 = 5a - b
By using the elimination method, we have:
-8 = 2a
a = -4
For the value of b, we have:
-2 = -3a + b
b = -2 + 3a
b = -2 + 3(-4)
b = -2 - 12
b = -14
For the value of c, we have:
c = -4a + 2b
c = -4(-4) + 2(-14)
c = 16 - 28
c = -12.
Substituting the values of a, b and c into the standard form of a quadratic equation:
ax² + bx + c = 0
-4x² - 14x - 12 = 0

The domain and range of the given inequality graph are; Domain: {x | -2 ≤ x ≤ 2} and Range: {x | -6 ≤ x ≤ 6}
What is the Domain and Range of the Function?The domain of a function is the set of all possible input values that make a function possible. Meanwhile the range of a function is the set of all possible output values that make a function possible.
Now, when dealing with an inequality graph, it is pertinent to note that a shaded dot implies less than or equal to (≤) or greater than or equal to (≥) while unshaded means less than or greater than.
Now. the range of the graph is closed from y = -6 to y = 6. Thus, the range is; {y| -6 ≤ y ≤ 6}

There is some overlap between the two groups, and 25% of the country's population has both had Covid and has also been vaccinated. Either having Covid or being vaccinated gives some protection against getting Covid. Based on these assumptions, if you choose a resident of this country at random what is the probability that the person has either had Covid or has been vaccinated and therefore has some protection against Covid?
The probability that the person has either had Covid or has been vaccinated and therefore has some protection against Covid is 45%

Equation: h(t) = 96t - 16t²
This equation will form a parabolaThe zeros of the parabola will indicate the start time and height (0,0) and the end time and height (x, 0)The maximum point will be the maximum height the ball will reachThe maximum point will be the halfway point between the two zerosStep-by-Steph(t) = 96t - 16[tex]t^{2}[/tex]
Find the zeros of the given equation:
Factor out the greatest common factor (GCF)
h(t) = 8t (12 - 2t)
The two factors are:
0 = 8t
0 = 12 - 2t
For both factors, solve for t
8t = 0
8t/8 = 0/8
t = 0
12 - 2t = 0
-2t = -12
t = 6
Now we have the x-values (t) of our zeros:
t = 0
(0, 0)
t = 6
(6, 0)
The ball will land on the ground at 6 seconds
Recall that the maximum point of the graph is halfway between the two zeros:
6 + 0 = 6
6 ÷ 2 = 3
The ball will reach its maximum height in 3 seconds
To find this height, substitute t for 3 in the given equation, and solve for h:
t = 3
h(3) = 96(3) - 16(3)²
= 288 - 16(9)
= 288 - 144
= 144
The maximum height the ball will reach is 144 feet
***Refer to the graph below to check your answer:
=======================================================
Explanation:
I'll use x in place of t
And use y in place of h(t)
The equation we have is y = 96x - 16x^2
This rearranges to y = -16x^2 + 96x
Compare this to y = ax^2+bx+c to find that
a = -16b = 96c = 0The x coordinate of the vertex is
h = -b/(2a)
h = -96/(2*(-16))
h = 3
Then plug this into the equation to find the value of y
y = -16x^2 + 96x
y = -16(3)^2 + 96(3)
y = 144
The y coordinate of the vertex is k = 144
The vertex is located at (h,k) = (3, 144) to represent the highest point of the parabola.
The max height of 144 feet occurs when the ball is in the air for 3 seconds.

Let the larger number be x
Then, the smaller number will be x-16
According to the question,
Larger number + smaller number = 50
So,
x+(x-16) = 50
2x = 50+16
2x = 66
x = 66÷2
