What is congruent triangles?
If each of the three corresponding sides and each of the three corresponding angles in two triangles equals one another, then the two triangles are said to be congruent.
We have to show that the the triangles ΔVWX and ΔEWG are congruent by using the AAS (angle, angle, side) criteria.
From the given reasons,
∠V ≅ ∠E
∠VWX ≅ ∠EWG
From this the AA criteria is satisfied.
We want sides of the triangle are congruent.
From the figure, GW ≅ WX
Therefore, by AAS the two triangles ΔVWX and ΔEWG are congruent.

Wha is the y intercept of the line given by the equation below y=4x - 6
Answers
When identifying parts of a slope-intercept equation, we can note that:
• The coefficient is the slope (represented by m)
• The constant is the y-intercept (represented by b)
In this equation, the constant (the integer by itself) is -6. The slope (the coefficient represented with a variable of x beside it) is 4. (0,-6) is the point on a coordinate plane in which the graphed line crosses the y-axis.
10. Sean promotes certain brands on his social media page for compensation. His monthly profit can be modeled using
the quadratic function p(x) = -0.00425x² +7z-1000, where p(x) is the amount of profit earned over
number of days. The graph of the function is shown. Use the graph to find the zeros of the function and interpret
them in context.
Answers
Answer:
The zeros are (158.017, 0) and (1489.042, 0)
The profit earned in 158.017 days and 1489.042 days is equal to 0. This means that Sean only earns money (makes a profit) when the amount of days he promotes a brand is greater than 158.017 but less than 1489.042 days.

Answers
The x-intercept of the equation, 1.50 x + 2.50y = 60, is x = 40
The y-intercept of the equation, 1.50 x + 2.50y = 60, is y = 24
Determining the x-intercept and y-intercept of an equationFrom the question, we are to determine the x-intercept and y-intercept of the given equation.
The given equation is
1.50 x + 2.50y = 60
The x-intercept is the point where y = 0
and
The y-intercept is the point where x = 0
Determining the x-intercept
1.50x + 2.50y = 60
Put y = 0
1.50x + 2.50(0) = 60
1.50x + 0 = 60
1.50x = 60
x = 60/1.50
x = 40
The x-intercept is x = 40
Determining the y-intercept
1.50x + 2.50y = 60
Put x = 0
1.50(0) + 2.50y = 60
0 + 2.50y = 60
2.50y = 60
y = 60/2.50
y = 24
Hence, the y-intercept is y = 24
The x-intercept represent the number of pens that could be bought for $60 when one is not buying any notebooks.
The y-intercept represent the number of notebooks that could be bought for $60 when one is not buying any pens

Find the final balance earned in an account with $845 invested at 4% annual simple
interest for 18 months.
Answers
The final balance is $895.7.
What is simple interest?
Simple interest is a quick and easy method of calculating the interest charge on a loan. Simple interest is determined by multiplying the daily interest rate by the principal by the number of days that elapse between payments.
Interest = principal ×rate× time
Given, principal = $845
rate = 4%
time = 18 months = 3/2 years.
After substituting the values, we get
Interest = 845(4)(3/2)/100
= 50.7
Final balance = initial balance + interest
Therefore,
Final balance = 845 + 50.7
= $895.7

length of the base.
Answers
The length of the base is 22.1
An isosceles triangle with congruent sides of length 49.3 inches has a perimeter of 121.7 inches
An triangle is said to be isosceles if two sides of the trainagle have same length.
The two sides of this triangle is congurent that is they have same length = 49.3
perimeter of a triangle is the summation of all three sides.
Perimeter = length + base + length
121.7 = 49.3 + base + 49.3
base = 121.7 - 99.6
base = 22.1
Therefore, the length of the base is 22.1

find the value of b/a if a+1/b-1=5/1 and a-1/b+1=1/1
Answers
Answer:
1/2
Step-by-step explanation:
You want the value of b/a when (a+1)/(b-1)=5/1 and (a-1)/(b+1)=1/1.
SolutionThe latter equation tells you ...
a -1 = b +1
b = a -2
Then the first equation tells you ...
a +1 = 5(b -1)
a +1 = 5(a -2 -1) substitute for b
a +1 = 5a -15 . . . . eliminate parentheses
16 = 4a . . . . . . . . add 15 -a

What is Linear approximation ?
A linear approximation is an approximation of a general function using a linear function (more precisely, an affine function). They are widely used in the method of finite differences to produce first order methods for solving or approximating solutions to equations.
The formula is
L(x) = f(a) + f'(a) (x - a)
Given,
y = sin(2x)
Δx = 0.1 at x = 0
y'(x) = dy/dx = 2 cos 2x
As, x = 0
y'(0) = 2 cos 0
we know, cos 0 = 1
y'(0) = 2
Δy = y'(x) * Δx
= y'(0) * Δx
= 2 * 0.1
Δy = 0.2 (Approx value)
Exact value of Δy = sin(2 * 0.1) - sin 0
= sin(0.2) - 0
= 0.19867
% error = [ (Exact value - Approx value) / Exact value ] * 100
= [ (0.2 - 0.19867) / 0.19867 ] * 100
= 0.66945 or 0.67%
Hence, the percentage error is 0.67%

Answer:
y = - [tex]\frac{10}{3}[/tex] x + 1
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{3}{10}[/tex] x - 8 ← is in slope- intercept form
with slope m = [tex]\frac{3}{10}[/tex]
given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{3}{10} }[/tex] = - [tex]\frac{10}{3}[/tex] , then
y = - [tex]\frac{10}{3}[/tex] x + c ← is the partial equation of line h
to find c substitute (3, - 9 ) into the partial equation
- 9 = - 10 + c ⇒ c = - 9 + 10 = 1
y = - [tex]\frac{10}{3}[/tex] x + 1 ← equation of line h

The trigonometric ratio tan(2 sin⁻¹(x)) is expressed as 2sec(x)
Trigonometric RatioThe six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec). In geometry, trigonometry is a branch of mathematics that deals with the sides and angles of a right-angled triangle. Therefore, trig ratios are evaluated with respect to sides and angles.
In the question given, we have;
tan(2 sin⁻¹(x))
tan = sin / cos
sin/cos(2 * 1/sin x)
