Answer:

[tex](-4,-13)[/tex] and [tex](4,3)[/tex] the intersection points.

Step-by-step explanation:

Intersection point of two functions is a common point which satisfies both the functions.

Given functions are,

[tex]f(x)=2x-5[/tex]

[tex]g(x)=x^2+2x-21[/tex]

For a common point of these functions,

[tex]f(x)=g(x)[/tex]

[tex]2x-5=x^2+2x-21[/tex]

[tex]-5=x^2-21[/tex]

[tex]0=x^2-16[/tex]

[tex]x^2=16[/tex]

[tex]x=-4,4[/tex]

For [tex]x=-4[/tex],

[tex]f(-4)=g(-4)=2(-4)-5[/tex]

                       [tex]=-13[/tex]

For [tex]x=4[/tex],

[tex]f(4)=g(4)=2(4)-5[/tex]

                  [tex]=3[/tex]

Therefore, [tex](-4,-13)[/tex] and [tex](4,3)[/tex] the intersection points.

Given:

The table of values.

To find:

Whether the given relation in the table is proportional or non proportional.

Solution:

If y is directly proportional to x, then

[tex]y\propto x[/tex]

[tex]y=kx[/tex]

[tex]\dfrac{y}{x}=k[/tex]

Where, k is the constant of proportionality.

It means the ratio of y and x remains same for proportional relation.

From the given table, the points are (10,18), (11,18.6) and (12,19.2). The ratio of y to x for these points are:

[tex]\dfrac{18}{10}=1.8[/tex]

[tex]\dfrac{18.6}{11}\approx 1.69[/tex]

[tex]\dfrac{19.2}{12}=1.6[/tex]

Since the ratio of y to x for the given points are not equal, therefore the given relation is a non proportional relation.

Answer:

20°

Step-by-step explanation:

It's a catch. Draw a stronger line (along the circle) from V, going through Z, W, X, and getting to Y. That measures 320°.

Since the whole circle is 360° the segment YV measures 40°. Therefore, angle VXY = 20°.

Answer:

0.5

Step-by-step explanation:

Slope (m) =  

ΔY

ΔX

=  

1

2

= 0.5

θ =  

arctan( ΔY ) + 180°

ΔX

= 206.56505117708°

ΔX = 0 – 2 = -2

ΔY = 0 – 1 = -1

Distance (d) = √ΔX2 + ΔY2 = √5 = 2.2360679774998

Equation of the line:

y = 0.5x

When x=0, y = 0

When y=0, x = -0

Answer:

50

Step-by-step explanation:

68+62=130 then subract 180-130 and have 50 so x=50

Answer:

x°=50°

Step-by-step explanation:

Because of the Vertical Angle Theorem, the blank angle across from 68° is the same measure. Therefore, since the blank angle is 68°, then x° would be 50° because 180-62-68=50 due to the Triangle Angle Sum Theorem.

Answer:

7.97%

Step-by-step explanation:

Given data

Original Salary= $32,000

Increase= $2,550.00

percent increase= increase/original *100

Percent increase= 2,550.00/32000*100

Percent increase=  0.0796875*100

Percent increase= 7.97%

Hence the increase is  7.97%

Answer:

Step-by-step explanation:

hope this helps, have a great day/night!!

Answer:

15

Step-by-step explanation:

40=8(x - 10)

Distributive property

40 = 8x - 80

Add 80 on both side

120 = 8x

Divide both sides by 8

120/8 = 15

x = 15

11/4 -7/6

33/12 - 14/12

1 7/12

Answer:

1 3/4 - 1 1/6

= 10/4 - 7/6

Lcm of 4 and 6 = 2 ×2 × 3 = 12

= (10/4) × 3 = 30/12

(7/6) × 2 = 14/12

30/12 - 14/12 = 30-13/12 = 17/12

Step-by-step explanation:

Graph shrinks, that means for every x value there is a higher y value. So coefficient of x is definitely more than 1. Try to substitute x = 1 to (9x)^2 and (3x)^2.

(3(1))^2 = 9

The value of the expression (0.01) × (−0.1) × (10) × (−100) will be 1.

When the relevant components and basic processes of a numerical method are given values, the expression's result is the result of the computation it depicts.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The expression is given below.

⇒ (0.01) × (−0.1) × (10) × (−100)

Simplify the expression, then we have

⇒ (0.01) × (−0.1) × (10) × (−100)

⇒ (0.01) × (0.1) × (10) × (100)

⇒ 1

The value of the expression (0.01) × (−0.1) × (10) × (−100) will be 1.

Answer: B, Parallelogram, and rectangle

Step-by-step explanation:

A parallelogram requires two parallel sides which that shape has.

A rectangle requires all angles to be right angles and that shape has all angles being right angles.

The shape is not a rhombus since all sides are not the same and it's not a square for the same reason.

Answer:

Step-by-step explanation:

Apply the Pythagorean Theorem:

85^2 = 67^2 + h^2, where h is the height of the TV

Then 7225 = 4489 + h^2, or

h^2 = 2736, or h = +√2736 = 52.3 inches

The TV is 52.30 inches tall if the television is advertised as an 85-inch TV if the width of the TV is 67.

It is defined as a triangle in which one angle is 90 degrees and the other two angles are acute angles. In a right-angled triangle, the name of the sides are hypotenuse, perpendicular, and base.

We have:

A certain television is advertised as a 85 inch TV

It means the diagonal length is 85 inches.

Width of the TV = 67 inches

Let's suppose the TV is x inches Tall

So from the Pythagoras theorem:

[tex]\rm 85^2 = x^2+67^2[/tex]

7225 = x² + 4489

x = 52.30 inches

Thus, the TV is 52.30 inches tall if the television is advertised as an 85-inch TV if the width of the TV is 67.

Answer:

Reduction

Step-by-step explanation:

So, lets go over what we know:

The black rectnagle is the orginal shape.

The organe rectnalge is the new shape.

The organge rectangle is smaller than the black rectangle.

The rogane rectangle is a scaled image of the black rectangle.

So, enlargment is when a object has a scale factor that makes it bigger than the orgninal object.

Reduction, on the other hand, is when a object has a scale factor that makes it smaller than the orginal object.

As we can see, the organe rectnagle is much smaller than the black rectnalge.

So this must be reduction, since the organe rectangle has a small scale factor that causes the shape to shrink in size.

Hope this makes sense and helps you! :)
