Answer:

y= -x

y= 3/2 -5

Step-by-step explanation:

The sum of two numbers is zero.

x + y = 0

y = -x

Twice the smaller number subtracted from 3 times the larger number is 10.

Let x represent the larger number and y represent the smaller number.

Twice the smaller number: 2y

3 times the larger number: 3x

Twice the smaller number subtracted from 3 times the larger number is 10.

3x - 2y = 10

-2y = -3x + 10

y = 3/2 x - 5

The equations are:

y = -x

y = 3/2 x - 5

Answer:

55

Step-by-step explanation:

180−43−82=55(angles of a triangle add upto 180)

What would the measure of the third angle equal?

Well given that all 3 vertices of a triangle are supposed  to be a sum of 180*

Hence this information side E is 82* and side H is 43* and when added up they equal 125 so then you would subtract 180 - 125 =  55\

Therefore, side T = 55*

Answer:

s = ≥34

Step-by-step explanation:

The speed of the  truck, s, must be no less than 34 miles per hour

is s ≥ 34.

Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.

The symbol a < b indicates that a is smaller than b.

When a > b is used, it indicates that a is bigger than b.

a is less than or equal to b when a notation like a ≤ b.

a is bigger or equal value of an is indicated by the notation a ≥ b.

Given, The speed of a truck, s, must be no less than 34 miles per hour.

Therefore, The speed of the truck must be greater than or equal to 34 miles per hour.

So, The inequality that represents this context is,

s ≥ 34.

Answer:

y = -1/4x + 2

Step-by-step explanation:

Pick two points on the graph. Points (-4, 3) and (4, 1).

[tex]\frac{x_{2} - x_{1} }{y_{2} - y_{1} }[/tex]

[tex]\frac{3-1}{-4-4}[/tex]

= [tex]-\frac{1}{4}[/tex]

Slope is [tex]-\frac{1}{4}[/tex].

The y-intercept is the point where the line intersects the y-axis. In this case, it's (0, 2). So +2.

y = -1/4x + 2

Answer:

The 9-foot ladder would have a height of 8.55 ft against the house

Step-by-step explanation:

The angles made by the 9-foot ladder and 4-foot ladder that are leaning against the house is 71.8 degrees.

The situation forms a right angle triangle.

A right angle triangle has one of its angles as 90 degrees. The sides and angle can be found using trigonpometric ratios.

Therefore, the 9 foot and the 4 foot ladder forms the same angle.

The 4 foot ladder forms a 3.8 ft height against the wall.

Hence,

sin ∅ = opposite/ hypotenuse

sin ∅ = 3.8 / 4

∅= sin⁻¹ 0.95

∅ = 71.8051276612

∅ = 71.8°

Therefore, the angles made by the 9-foot ladder and 4-foot ladder that are leaning against the house is 71.8 degrees.

r = 14

r² = 196

C = 87.92

Step-by-step explanation:

Given:

r = 14

To find diameter:

Answer: The height of street sign = 15

Step-by-step explanation:

At the same time, the angle made by the light on each object is the same.

Pole and street sign both standing vertical to the ground.

So triangle made by both of them are similar

The sides of similar triangles are proportional,

[tex]\dfrac{\text{height of street sign}}{\text{height of pole}}=\dfrac{\text{Length of the shadow made by street sign}}{\text{Length of the shadow made by pole}}\\\\\dfrac{\text{height of street sign}}{40}=\dfrac{12}{32}\\\\\text{height of street sign}=\dfrac{12}{32}\times40=15[/tex]

Hence, the height of street sign = 15

Given:

The figure of a trapezium.

To find:

The measures of missing angle [tex]m\angle K, m\angle M[/tex].

Solution:

In the given figure [tex]JK\parallel ML[/tex].

If a transversal line intersect the two parallel lines, then the same sides interior angles are supplementary angles.

[tex]m\angle J+m\angle M=180^\circ[/tex]         (Supplementary angles)

[tex]87^\circ+m\angle M=180^\circ[/tex]

[tex]m\angle M=180^\circ-87^\circ[/tex]

[tex]m\angle M=93^\circ[/tex]

Similarly,

[tex]m\angle L+m\angle K=180^\circ[/tex]         (Supplementary angles)

[tex]51^\circ+m\angle K=180^\circ[/tex]

[tex]m\angle K=180^\circ-51^\circ[/tex]

[tex]m\angle K=129^\circ[/tex]

Therefore, [tex]m\angle M=93^\circ[/tex] and [tex]m\angle K=129^\circ[/tex].
