HELP!!!!
m_a_m_a [10]

Answer:

(0,0)

Step-by-step explanation:

The coordinates of C now are (-7,-5).

Moving C -3 on the x-axis will move -7 - 3 = -10. C is now located on (-10,-5).

Moving C +5 on the y-axis will move -5 + 5 = 0. C is now located on (-10,0).

Moving C on the y-axis +10 will move -10 + 10 = 0. C is now located on (0,0).

C is translated to (0,0).

Expand
ddd [48]

Answer:

The working of expressions is shown below.

Step-by-step explanation:

We are given the following information:

a) Expand

3(x+4)\\3\times x + 3\times 4\\3x + 12

b) Expand and simplify

4(x+5)-2(x-3)\\=(4x + 20) -(2x-6)\\=( 4x-2x) + (20 + 6)\\= 2x + 26\\=2(x +13)

c) Expand

(x+2)(x+7)\\=x\times x + x\times 7 + 2\times x + 2\times 7\\= x^2 + 7x + 2x + 14\\=x^2 + 9x +14

d) Factorize fully

12x-18\\=6(2x-3)

What is the slope of the line? y = 10​
Feliz [49]

Answer:

0

Step-by-step explanation:

The equation is written in slope-intercept form [ y = mx + b ]

In the equation [ y = 10 ], there is no variable that represents m and we know that because no number has an "x" after it.

The only number that could remove the variable of "m" and "x" would be 0.

Best of Luck!
