Paraphin [41]3 years ago
5 0

Answer:

x = 46

Step-by-step explanation:

sqrt(3x - 17) + 5 = 16

Subtract the numbers

sqrt(3x - 17) = 11

Square both sides

3x - 17 = 121

Solve the linear equation

x = 46

igor_vitrenko [27]

Answer:

The values of y would be -9 and 15

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

we have

d=13\ units

S(-2,3) and T(3,y)

substitute the given values in the formula and solve for y

13=\sqrt{(y-3)^{2}+(3+2)^{2}}

13=\sqrt{(y-3)^{2}+25}

squared both sides

169=(y-3)^{2}+25

(y-3)^{2}=169-25

(y-3)^{2}=144

take square root both sides

y-3=(+/-)12

y=3(+/-)12

y=3(+)12=15

y=3(-)12=-9

therefore

The values of y would be -9 and 15

Solve equations show all steps 1. 2x-10=44+8x 2. 7x-4=20=3x 3. 2(x-3)=-20 4. 15-4x+5=32
Inga [223]

Answer:

2x - 10 = 44 + 8x

7x - 4 = 20 =3x

2(x-3) = -20

15 - 4x + 5 = 32

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    2*x-10-(44+8*x)=0

Pull out like factors :

  -6x - 54  =   -6 • (x + 9)

  -6   =  0

 Solve  :    x+9 = 0

Subtract  9  from both sides of the equation :

                     x = -9

x = -9

Move all terms containing

x

to the left side of the equation.

4

x

−

=

20

Move all terms not containing

x

to the right side of the equation.

4

x

=

24

divide each term by 4

x = 6

2(x−3)=−20

Step 1: Simplify both sides of the equation.

2(x−3)=−20

2x−6=−20

Step 2: Add 6 to both sides.

2x−6+6=−20+6

2x=−14

Step 3: Divide both sides by 2.

2x

2

=

−14

2

x=−7

−4x+20=32

Step 2: Subtract 20 from both sides.

−4x+20−20=32−20

−4x=12

Step 3: Divide both sides by -4.

−4x

−4

=

12
