Answer:

-2

Step-by-step explanation:

you must follow the y=mx+b

m=slope

b=intercept

Answer:

B) -2

Step-by-step explanation:

y= -2x+11 is in slope-intercept form

y= mx+b

y= y-coordinate

x= x-coordinate

m= slope

b= y-intercept

m= -2

Answer:

(-8, 2)

Step-by-step explanation:

Start with (-3, 4).  Subtract 5 units from -3, obtaining -8, and subtract 2 units from 4, obtaining 2:  (-8, 2)

Answer:

x=17

Step-by-step explanation:

So first we know that vertical angles are equal

And for the first part we have a 73 and x

So 73+x=90 Becuase in this situation if you add them up its gonna give you a right angle

you’ll get 17

SO 17 is X

Answer:

It is 8,7

Answer:

A dialation followed by a reflection

Step-by-step explanation:

When you dialate a shape it changes the size which makes the shape similar but not congrouent.

The option “a dilation followed by a reflection” will produce an image that is not congruent to its pre-image option, fourth is correct.

It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.

As we know, the translation will shift the object.

If rotate the image with 90 degree about origin will change the orientation of the image but shape will remains same.

A dilation followed by reflection will change the image because the transformation dilation is used to resize an item. Dilation is a technique for making items appear larger or smaller.

Thus, the option "a dilation followed by a reflection" will produce an image that is not congruent to its pre-image option fourth is correct.

he criteria for polygon inscribed in a circle is every vertices are points on the circle and all sides are included within the circle.

Polygon is "any two closed curve consisting of a set line segments connected such that no two segments connected".

According to the question,

A polygon is inscribed in a circle if its all vertices are points on the circle and all sides(Edges) are included within the circle. All regular polygon can be inscribed in a circle. The center of an inscribed polygon is also the center of the circumscribed circle.

Hence, the criteria for polygon inscribed in a circle is every vertices are points on the circle and all sides are included within the circle.

Answer:

c + d = 400

0.2c + 0.5d = 156

Step-by-step explanation:

Let

c = number of liters of 20% acid solution

d = number of liters of 50% acid solution.

c + d = 400 (1)

0.2c + 0.5d = 400(0.39)

0.2c + 0.5d = 156 (2)

From (1)

c = 400 - d

Substitute c = 400 - d into (2)

0.2c + 0.5d = 156 (2)

0.2(400 - d) + 0.5d = 156

80 - 0.2d + 0.5d = 156

- 0.2d + 0.5d = 156 - 80

0.3d = 76

d = 76/0.3

d = 253.33 liters

Substitute d = 253.33 into (1)

c + d = 400

c + 253.33 = 400

c = 400 - 253.33

c = 146.67 liters

The interest is: $2550.00

Step-by-step explanation:

I = P x r x t

    P is the principal amount, $12000.00.

   r is the interest rate, 4.25% per year, or in decimal form, 4.25/100=0.0425.

   t is the time involved, 5....year(s) time periods.

   So, t is 5....year time periods.

To find the simple interest, we multiply 12000 × 0.0425 × 5 to get that:

The interest is: $2550.00

Answer:

B = -3

Step-by-step explanation:

YES

Base=b

Height= h

Area 1=A1=1/2*b*h

Base=b

Height= 4h

Area of triangle 2=A2=1/2*b*4h

A2/A1= (1/2*b*4h)/(1/2*b*h)

= (1/2*b*4h)/(1/2*b*h)

=4/1

Ratio of heights =h2/h1= 4/1

Ratio of areas =A2/A1= 4/1

They are proportional.

Answer:

i) the length is 10cm

ii) the perimeter is 36 cm

Step-by-step explanation:

i) We know that Area of a rectangle can be found by using the following formula...

A = l x w

(where A is area of the triangle, l is the length of the triangle, and w is the width of the rectangle).

From this we know that

l = A/w

[tex]l = 80cm^{2} / 8cm = 10cm[/tex]

ii) Now that we know both the length and the width we know we can find the perimeter by using the following formula...

P = 2(l + w)

[tex]P = 2(10cm+ 8cm )\\P = 20cm + 16cm\\P = 36cm[/tex]
