Answer 1
Answer: You should just have to multiply each coordinate by the scale factor, giving
F’ (1.5,1.25)
G’ (2.5,0.25)
H’ (0.5,0.25)
Answer 2
Answer:

Answer:

The first option

Step-by-step explanation:

The coordinates of each point divided by 4 matched up with the ones on that answer so it's the first one. it's proportional so I think that's it.

These cuboids are made from small cubes. Write how many small cubes there are in each cuboid

Answers

The number of small cubes in each cuboid is:

(a) 3, b) 6, c) 27, and d) 16.

Given are four cuboids.

It is required to find the number of small cubes that are used to make these cuboids.

a) There are only 3 small cubes.

b) There is only one step of cubes.

Number of cubes = 3 + 3 = 6

c) There are 3 cubes arranged horizontally and 3 cubes arranged vertically through each surface.

Number of cubes in one step = 3 × 3 = 9

There are 3 steps like that.

So, total number of cubes = 3 × 9 = 27

d) There are 4 cubes in the horizontal position.

And there are 4 cubes going down.

Total number of cubes = 4 × 4 = 16

Solve for t(advanced rational equations)

Answers

t² -7 + 12t⁻² = 0

Multiply each side by t² :

t⁴ -7t² + 12 = 0

This is a quadratic equation in the variable ' t² '.
For just a moment, to avoid confusion, let U = t².
Then the equation is

U² - 7U + 12 = 0
whence
(U - 4) (U - 3) = 0
and
U = 4   and   U = 3 .

Now we can go back to ' t² ' in place of U :

t² = 4
t = +2  and  t = -2

t² = 3
t = +√3  and  t = -√3

                                       
t^2-7+12t^(-2)=0\n t^4-7t^2+12=0\n t^4-3t^2-4t^2+12=0\n t^2(t^2-3)-4(t^2-3)=0\n (t^2-4)(t^2-3)=0\n (t-2)(t+2)(t^2-3)=0\n t=2 \vee t=-2 \vee t=-√(3)\vee t=\sqrt3

Answers

To do this, you simply substitute 7 into the equation. 

[(7) + 1][(7) − 2]
BODMAS tell us that we should do the sum in the brackets before anything else.

The seventh term is 40. The answer is D)

What is the solution to the linear equation? 6k+10.5=3k+12

Answers

Answer:

k=0.5

Step-by-step explanation:

Given: The linear equation 6k+10.5=3k+12.

To find: The solution of the linear equation.

Solution: The given linear equation is:

6k+10.5=3k+12

Rewriting the like terms, we get

6k-3k=12-10.5

Solving the above equation, we have

3k=1.5

k=(1.5)/(3)

k=0.5

which is the required solution to the linear equation.

the answer is k=0.5 hope it helps

2.) What value for c will make the expression a perfect square trinomial?x2 – 7x + c

-49/4
-7/2
7/2
49/4

Answers

Answer : (49)/(4)

Given expression is x^2 - 7x + c

To make perfect square trinominal we use completing the square method

In completing the square method we add and subtract the half of square of coefficient of middle term

Here coefficient of middle term is -7

Half of -7 is (-7)/(2)

Square of (-7)/(2) is ((-7)/(2))^2 = (49)/(4)

So the expression becomes x^2 - 7x + [tex] (49)/(4) that gives perfect square trinomial

Hence , the value of 'c' is (49)/(4)


The value for c will make the expression a perfect square trinomial is 49/4

How to determine the value of c?

The equation is given as:

x^2 - 7x + c

Take the coefficient of x

k = -7

Divide it by 2

k/2 = -7/2

Square both sides

(k/2)^2 = (-7/2)^2

The above represents the value of c.

So, we have:

c = (-7/2)^2

Evaluate

c = 49/4

Hence, the value for c will make the expression a perfect square trinomial is 49/4
