Answer:

f(x) = { 3, 1, -1, -3 }

Step-by-step explanation:

f(x) = −2x + 5

when

x=1

f(1) =−2 * 1 + 5 = -2 + 5 = 3

x=2

f(2) = −2 * 2 + 5 = -4 + 5 = 1

x=3

f(3) = −2 * 3 + 5 = -6 + 5 = -1

x=4

f(4) = −2 * 4 + 5 = -8 + 5  = -3

Answer:

f(x) = { 3, 1, -1, -3 }

Answer: Calita saw 30 Robins and  6 Cardinals

Step-by-step explanation:

Step 1

  writing the mathemathecal expression  becomes

Let robins be represented as R

and Cardinals be represented as C

so our first equation becomes

R+C = 36----- eqn 1

but she saw 5times as many robins as cardinals, with a total of 36 birds making us have

Therefore R= 5C

 5C +C= 36------- eqn 2

STEP  2--- solving equation 2

5C+C = 36

6C= 36

C= 36/6=6

Puting the valueof C=6 in equation 1 becomes

R+C= 36

R+6=36

R=36-6= 30

R=30

Therefore Calita saw 30 Robins and  6 Cardinals

Answer:

The scale factor is One-eighth

The coordinates of C prime are (0.75, 0.5).

The coordinates of B prime are (–0.25, 1).

Step-by-step explanation:

A triangle has vertices at A(–2, 4), B(–2, 8), and C(6, 4). If A prime has coordinates of (–0.25, 0.5) after the triangle has been dilated with a center of dilation about the origin, which statements are true? Check all that apply. The coordinates of C prime are (0.75, 0.5). The coordinates of C prime are (1.5, 1). The scale factor is One-eighth. The scale factor is 8. The scale factor is One-fourth. The scale factor is 4. The coordinates of B prime are (–0.25, 1). The coordinates of B prime are (–0.5, 2).

Solution:

Transformation is the movement of a point from its initial location to a new location. If an object is transformed then all its points are also transformed. Types of transformation are reflection, dilation, rotation and translation.

Dilation is the enlargement or reduction in size of an object. If a point X(x, y)  is dilated about the origin by a factor k, its new location is X'(kx, ky)

Triangle ABC with vertices at A(–2, 4), B(–2, 8), and C(6, 4) is dilated to give A'(-0.25, 0.5)

kA = A'

(-2k, 4k) = (-0.25, 0.5)

-2k = -0.25, hence k = 1/8

Therefore the scale factor is 1/8 (one- eight)

The new location of the vertices is B'(-0.25, 1), C'(0.75, 0.5)

Step-by-step explanation:

3y/4 = 36

3y = 36 × 4

3y = 144

y = 48

Hence,

The value of y = 48.

Answer:

y=-4x-33

Step-by-step explanation:

Since the equation is parallel it will have the same slope which is -4

Now just plug in the points into the equation y=-4x+n

Plug them in and you get -5=-4(-7)+n

Then solve which will get you n=-33

Therefore the equation is y=-4x-33

The linear equation that is solved by both (-6,2) and (0,-4) is y = -x - 4

Using the slope intercept formula for linear equation,

where

m = slope

b = y-intercept

Therefore, lets find m

(-6,2) and (0,-4)

m = -4 - 2 / 0 - (-6) = -6 / 6 = - 1

Lets find b using (0,-4)

y = mx + b

-4 = -1(0) + b

b = -4

There the linear equation in slope intercept form will be as follows

Answer:

3 pencils per jar

hope it helps you

The number of pencils in each jar will be 3.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that there are 24 pencils in 8 jars. The number of pencils in each jar will be calculated as,

Number = Number of pencils / Number of the jars

Number = 24 / 8

Number = 3 Pencils

Hence, there will be 3 pencils in each jar.

Answer:

18,1,18

Step-by-step explanation:

The slope of a line from the given graph is 4 units.

From the given graph, vertical line (rise) = 16 and horizontal line (run) = 4.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

Now, slope = Rise/Run

⇒ slope = 16/4

= 4 units

Therefore, the slope of a line from the given graph is 4 units.
