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]

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

Answer:

There is a strong correlation with one outlier and this forms a pattern going up

Trust me I had trouble and my teacher showed me how to get it.

Answer:

There are 6 points and one outlier in this graph. Excluding the lowest and highest points, four dots are left to set up the trend line. Among these points, we can see the dots lowering when moving to the right side.

This means the trend line is negative.

For correlation, it is clear that the four dots are well organized in descending manner. Because of this, the graph will still have a high negative correlation even with the outlier(s). Therefore the plots in this graph have a strong negative correlation.

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:

21 m²

Step-by-step explanation:

Area of a trapezoid is given by the formula:

A = (a+b)/2×h

(where h is the vertcial height, and a and b are the parallel lines)

Substituting values given gives us:

A = (5+9)/2×3

A = 14/2×3

A = 7×3

A = 21

Units will be m² as this is area.

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.

The value of x which will make the provided triangles similar by the sss similarity theorem is 77.

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.

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]

[tex]\\ \rm\Rrightarrow cosy+siny=\dfrac{1}{2}+\dfrac{\sqrt{3}}{2}[/tex]

[tex]\\ \rm\Rrightarrow cos\dfrac{\pi}{3}+sin\dfrac{\pi}{3}=\dfrac{1}{2}+\dfrac{\sqrt{3}}{2}[/tex]
