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

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.

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
Question 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.

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:

Grace measured a line to be 15.6 inches long. If the actual length of the line is 15.3
inches, then what was the percent error of the measurement, to the nearest tenth of a
percent?
The percentage error of the measurement, to the nearest tenth of a percent 2.6%.
Given, Grace measured a line to be 15.6 inches long.
The actual length of the line is 15.3 inches.
Percentage error of the measurement = ?
Error in the measurement = 15.6 - 15.3
= 0.3 inches
Percentage error = 0.4 ÷ 15.3
= 0.02614 × 100
= 2.6%
The percentage error = 2.6%
Hence the percentage error is 2.6% .
