Answer:

3

Step-by-step explanation:

to start this

you need to open the bracket, by multiplying -3(8-f)

we get

-5f = -3*8 -3 * (-f)

-5f = -24 + 3f

we collect like terms by taking f to where there is f so as to simplify our work

so we get

-5f -3f = -24

we get -3f because when a sign  + or - crosses an equal sign, the sign changes that is. + changes to -, while - chnages to +

so add them

-8f = -24

minus (-) will cancel minus the we get

8f = 24

divide both side by 8

8f/8 = 24/8

f = 3

so f is = 3

Answer:

Step-by-step explanation:

-5f=-3(8-f)

Opening bracket

-5f = - 24 + 3f

Collecting like terms

-5f - 3f = -24

-8f = -24

Dividing by -8

f = -24/-8

f = 3

Point A is (5, 7).
spin [16.1K]

The coordinate of point B is at (29, -15): Option C is correct.

The formula for calculating the midpoint of two points is expressed as:

M(x, y) = {\frac{x_2+x_1}{2}, \frac{y_2+y_1}{2}}

Given the coordinate points

A is (5, 7).

B is (x, y).

M is (17, -4)

Substituting into the formula to get x and y

17 = 5+x/2

5+x = 34

x = 34 - 5

x = 29

Get the value of y. Similarly;

-4 = 7+y/2

-8 = 7+y

y = -8-7

y = -15

Hence the coordinate of point B is at (29, -15)

Ganezh [65]

Answer:

5 times the sum of the digits of the number is 9 less than the number formed by reversing digits. → x = (5y - 9)/4 -- equation (1). Case - 2 : And, 4 times the value of the digits at ones place is equal to half the place value of digit at tens place (10x/2).
