Which equation can be used to solve for x in the following diagram?
Answer:
D
Step-by-step explanation:
Answer:
D
Step-by-step explanation:
10x + 10 and 110 are vertical angles and are congruent, thus
10x + 10 = 110 → D
Subtract 10 from both sides
10x = 100 ( divide both sides by 10 )
x = 10

in the diagram, AB is parallel to DE. Also, DE is drawn such that the length of DE is half the length of AB. If sin A=0.5, then what is sin E?
Answer:
I got sin E = 0.5
Thus answer choice C being the correct choice
Hope this helps ;)
Step-by-step explanation:
For given diagram, sin(E) = 0.5
What is transversal?"It is a line that passes through two lines in the same plane at two distinct points."
What are parallel lines?"These are the lines in the plane that are at equal distance from each other and never meet."
For given question,
AB is parallel to DE.
We can observe that, the line segment AE is transversal.
So, ∠DEF and ∠FAB are alternate interior angles.
We know, when a transversal intersects two parallel lines, then each pair of alternate interior angles is equal.
⇒ ∠FAB = ∠DEF
⇒ ∠A = ∠E
⇒ sin(A) = sin(E)
As, sin(A) = 0.5
⇒ sin(E) = 0.5
Therefore, sin(E) = 0.5

Joe Casey, the star of the Placer County All-Star baseball team, has hit 11 home runs in the team's first thirty games. If he continues this pace how many home runs will he hit in a 162 game season? How many home runs is he expected to hit?
Answer: 59.4
Step-by-step explanation:
We can solve this by using direct proportion where y = kx
y = number of games
x = number of home runs
k = constant of proportionality
Since y = kx
30 = 11k
k = 30/11
The home runs will he hit in a 162 game season will then be:
= 162 ÷ 30/11
= 162 × 11/30
= 59.4
Answer: 59.4

What is Arithmetic progression?An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant.
The nth term of AP : a_n = a + (n – 1) × d
here, we have,
given that,
a 2 = -39
a 2 = a 1 + 12
- 39 = a 1 + 12
a 1 = - 39 - 12
a 1 = - 51 ( first term )
The common difference is : d = 12
The explicit rule for the arithmetic sequence:
a n = a1 + ( n - 1 ) d
a n = -51 + ( n - 1 ) · 12
Hence, The solution is, the explicit rule for the arithmetic sequence is
a n = -51 + ( n - 1 ) · 12 .

Write an equation of the line that passes through (4,−1) and is parallel to the line y=3x+7.
The equation of the line that passes through (4,−1) and is parallel to the line y=3x+7 will be y = 3x - 13.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that line that passes through (4,−1) and is parallel to the line y = 3x+7. If the line is parallel then the slope will be equal to the parallel line.
m = 3
The equation of the line will be written as,
y = 3x + c
The y-intercept will be calculated as,
y = 3x + c
-1 = ( 3 x 4) + c
c = -13
The equation will be,
y = 3x - 13
Therefore, the equation of the line that passes through (4,−1) and is parallel to the line y=3x+7 will be y = 3x - 13.

Find the equation of the line that passes through the given points. Write the equation in slope-intercept form.
(-2.7) and (-1,5)
Answer:
The equation in the slope-intercept form will be:
y = -2x + 3Step-by-step explanation:
Given the points
(-2, 7)(-1, 5)Finding the slope between the points
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-2,\:7\right),\:\left(x_2,\:y_2\right)=\left(-1,\:5\right)[/tex]
[tex]m=\frac{5-7}{-1-\left(-2\right)}[/tex]
[tex]m=-2[/tex]
We know that the slope-intercept of line equation is
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
substituting m = -2 and the point (-2, 7) to find the y-intercept 'b'
y = mx+b
7 = -2(-2) + b
7 = 4 + b
b = 7-4
b = 3
so the y-intercept = b = 3
substituting m = -2 and b = 3 in the slope-intercept form of line equation
y = mx+b
y = -2x + 3
Thus, the the equation in the slope-intercept form will be:
y = -2x + 3Question 28 i need a little assistance with the problem
We need to know about distance of a point from a line to solve the question. The distance of point (9,5) from the line 4x-3y=-4 is 5 units.
The distance between two points is calculated by taking square root of the sum of the squares of the difference between the coordinates of the two points. But for the distance between a point and a line we can't use this formula. To find the distance between a point and a line we take the shortest distance between them which is the perpendicular distance between the point and the line. The perpendicular distance is the length of the perpendicular dropped on the line from the point. Let the point (x_,y_) and the line be ax+by+c=0 then the formula for the distance between them is given by
[tex]d=\frac{|ax_+by_+c|}{\sqrt{a^{2} +b^{2} } }[/tex]
Here (x_,y_) is (9,5) and the line is 4x-3y=-4
The distance between the line and the point is :
[tex]d=\frac{|36-15+4|}{\sqrt{16+9} }=\frac{25}{5} =5[/tex]
Therefore we found out that the distance between the point (9,5) and the line 4x-3y=-4 is 5 units.

Choose the best description for the real number 34 over 3
We need to know aut rational numbers to solve this problem. The correct answer is C, rational because it is a fraction.
Rational numbers are numbers that can be written as p/q where q is not equal to zero. In this question 34 over 3 can be written as a fraction, 34/3 where 3 is not equal to zero, so we can safely say that 34 over 3 is a rational number. Now for the reasoning part,
34/33= 11.333...
So we can see that the fraction 34/3 is a repeating decimal and not a terminating decimal. Repeating decimal is a decimal where the numbers after the decimal point keep repeating without an ending. Terminating decimal is a decimal in which the decimal terminates at one point. We can see that in this question 34/3 is not a terminating decimal.
Therefore we see that the best description for 34 over 3 is that it is a rational because it is a fraction.So option C is the correct answer.

Answer:
The coordinates of point F would be: (x, y) = (8.2, 5.7)
Step-by-step explanation:
We know that the location of a point P on a coordinate plane can be determined by checking the value of the x-coordinate and the corresponding y-coordinate.In other words, the location of a point P with the x-coordinate and the corresponding y-coordinate will be: P(x, y)
Using the same concept, we can determine the coordinates of point F.The location of point 'F' lies on the x = 8.2 (x-coordinate) and their corresponding value of y=5.7 (y-coordinate).
i.e at x = 8.2, y = 5.7
Thus, the coordinates of point F would be: (x, y) = (8.2, 5.7)

The graph of f passes through (-2,7) and is perpendicular to the line whose equation is x= -16.
The equation of the function is
Answer:
y = 7
Step-by-step explanation:
x = -16 is a vertical line.
All lines perpendicular to a vertical line are horizontal lines. All horizontal lines have a slope of 0
so m = 0, y = 7, x = -2
y = mx + b
7 = 0(-2) + b
b = 7
so,
y = 0x + 7
y = 7
