What's the equation of the line that passes through the points (–8,4) and (0,22)?
Answer:
C
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 )
calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 8, 4 ) and (x₂, y₂ ) = (0, 22 )
m = [tex]\frac{22-4}{0-(-8)}[/tex] = [tex]\frac{18}{0+8}[/tex] = [tex]\frac{18}{8}[/tex] = [tex]\frac{9}{4}[/tex]
the line crosses the y- axis at (0, 22 ) ⇒ c = 22
y = [tex]\frac{9}{4}[/tex] x + 22 ← equation of line
What value of x will make the triangles similar by the sss similarity theorem? 15.9 59 77 96.8
The value of x which will make the provided triangles similar by the sss similarity theorem is 77.
What is SSS similarity theorem?The SSS similarity theorem is the theorem which is used to check the two triangle are similar or not.
SSS means the side-side-side. This theorem states that if all the three sides of a triangle are proportional to the three corresponding sides of the another triangle, then the triangles are similar.
In the given image, the sides of the first triangle are 35,20 and 20. The sides of the second triangle are x, 44,44.
Thus, by the SSS similarity theorem,
[tex]\dfrac{x}{35}=\dfrac{44}{20}\\x=\dfrac{44\times35}{20}\\x=77[/tex]
The value of x which will make the provided triangles similar by the sss similarity theorem is 77.

An element with mass 630 grams decays by 18.8% per minute. How much of the
element is remaining after 7 minutes, to the nearest 10th of a gram?
Answer:
-199.1
Step-by-step explanation:
18.8% × 7= 131.6%
630×131.6=82908 move the decimal two places to the left you get 829.08
630-829.08= -199.08 round to the nearest tenth you get -199.1

b.
Answer:
b = c = 75°
Step-by-step explanation:
b and 105° are adjacent angles and sum to 180° , then
b + 105° = 180° ( subtract 105° from both sides )
b = 75°
b and c are vertically opposite angles and are congruent , so
c = b = 75°

Answer:
y = [tex]\frac{\pi}{3}[/tex]
Step-by-step explanation:
using the addition formula for sine
sin(x + y) = sinxcosy + cosxsiny
then
sinxcosy + cosxsiny = [tex]\frac{1}{2}[/tex] sinx + [tex]\frac{\sqrt{3} }{2}[/tex] cosx
for the 2 sides to be equal , then
cosy = [tex]\frac{1}{2}[/tex] and siny = [tex]\frac{\sqrt{3} }{2}[/tex]
then
y = [tex]cos^{-1}[/tex] ([tex]\frac{1}{2}[/tex] ) = [tex]\frac{\pi }{3}[/tex]
and
y = [tex]sin^{-1}[/tex] ( [tex]\frac{\sqrt{3} }{2}[/tex] ) = [tex]\frac{\pi }{3}[/tex]
thus y = [tex]\frac{\pi }{3}[/tex]
[tex]\\ \rm\Rrightarrow sin(x+y)=\dfrac{1}{2}sinx+\dfrac{\sqrt{3}}{2}cosx[/tex]
[tex]\\ \rm\Rrightarrow sinxcosy+cosxsiny=\dfrac{1}{2}sinx+\dfrac{\sqrt{3}}{2}cosx[/tex]
Cancel sin and cos[tex]\\ \rm\Rrightarrow cosy+siny=\dfrac{1}{2}+\dfrac{\sqrt{3}}{2}[/tex]

The area of rectangle field is 12 3/5 m² if the length of the field is 6 2/3 m . Find its breadth
Answer:
[tex]1\frac{89}{100}[/tex] m
Step-by-step explanation:
The formula to find the area of a rectangle: [tex]l * b[/tex], where [tex]l[/tex] is the length and [tex]b[/tex] is the breadth.
1) Substitute the values into the formula.
[tex]12\frac{3}{5} = 6\frac{2}{3} * b[/tex]
2) Change it to an improper fraction and solve for [tex]b[/tex].
[tex]\frac{63}{5} = \frac{20}{3} * b[/tex]
[tex]\frac{3}{20}[/tex] * [tex]\frac{63}{5}[/tex] = [tex]b[/tex]
[tex]\frac{189}{100} = b[/tex]
3) Change it to a mixed fraction because the length is in a mixed fraction. To do it, do a long division.
= [tex]1\frac{89}{100}[/tex]

An arrow points from line D1 to line D2, which is identical in shape to line D1, but shifted one unit to the positive x direction. Dashed lines extend in the positive x direction from P1 and in the positive y direction from Q1, intersecting line S and line D1. Dashed lines extend in the positive x direction from P2 one unit in the positive y direction from P1 and in the positive y direction from Q2 one unit in the positive x direction from Q1, intersecting line S and line D2.

Find the slope of the following equation. Simplify your answer.
5x + 2y = -10
m= -5/2
m= 5
m= 2
m= 2/5
Answer:
1st option
Step-by-step explanation:
theequation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
5x + 2y = - 10 ( subtract 5x from both sides )
2y = - 5x - 10 ( divide terms by 2 )
y = - [tex]\frac{5}{2}[/tex] x - 5 ← in slope- intercept form
with slope m = - [tex]\frac{5}{2}[/tex]
