Consider this system of equation. Which shows the second equation written in slope-intercept form?y = 3x - 210(x+3/5)=2yA) y=5x+

SashulF [63]

we have that

y = 3x - 2

10(x+3/5)=2y------> the second equation----->divide by 2 both sides

5(x+3/5)=y-----> y=5x+3

y=5x+3------> second equation written in slope-intercept form

case A) y=5x+3/10-----> is not equal to y=5x+3

case B) y=5x+3--->is equal to y=5x+3---------> is the answer

case C) y=1/5x+3/25-------> is not equal to y=5x+3

case D) y=1/2x+6-----> is not equal to y=5x+3

therefore

the answer is the option

B) y=5x+3

Operations with Radical Expressions

lisov135 [29]

Answer: $30\sqrt{11}$

Step-by-step explanation:

$3\sqrt{50} * \sqrt{22}$

= $3\sqrt{5*5*2} * \sqrt{2*11}$

= $3\sqrt{5*5*2*2*11}$

= $3*5*2\sqrt{11}$

= $30\sqrt{11}$

******************************************

Answer: $6\sqrt{30}$

Step-by-step explanation:

$\sqrt{20} * \sqrt{3} * \sqrt{18}$

= $\sqrt{2*2*5} * \sqrt{3} * \sqrt{3*3*2}$

= $\sqrt{2*2*5*3*3*3*2}$

= $2*3\sqrt{5*3*2}$

= $6\sqrt{30}$

********************************************

Answer: $-\sqrt{5}$

Step-by-step explanation:

$4\sqrt{20} - 3\sqrt{45}$

= $4\sqrt{2*2*5} - 3\sqrt{3*3*5}$

= $4*2\sqrt{5} - 3*3\sqrt{5}$

= $8\sqrt{5} - 9\sqrt{5}$

= $-\sqrt{5}$

********************************************

Answer: $4\sqrt{5}$

Step-by-step explanation:

$2\sqrt{5} + 3\sqrt{5} - \sqrt{5}$

= $(2+3-1)\sqrt{5}$

= $4\sqrt{5}$

********************************************

Answer: $46\sqrt{2}$

Step-by-step explanation:

$4\sqrt{32} + 6\sqrt{50}$

= $4\sqrt{2*2*2*2*2} + 6\sqrt{2*5*5}$

= $4*2*2\sqrt{2} + 6*5\sqrt{2}$

= $16\sqrt{2} + 30\sqrt{2}$

= $46\sqrt{2}$

Lucia made a scale drawing of a game room. The pool table is 3 inches long in the drawing. The actual pool table is 9 feet long.

3 feet is equal to 1 inch if she measured 3 inches to equal 9 feet

6x^2 + 23x + 7 NEED HELP SOLVING QUADRATIC EQUATION

luda_lava [24]

Answer:

6x2 + 23x + 7 = 0

Factorization:

(2x + 7)(3x + 1) = 0

Solutions based on factorization:

2x + 7 = 0 ⇒ x1 = −7

= −3.5

3x + 1 = 0 ⇒ x2 = −1

≈ −0.333333

Extrema:

Min = (−1.916667, −15.041667)

Step-by-step explanation: hope this helps

Make t the subject of this formula. r = 7 (t + 3)

kari74 [83]

Answer:

t= r-21

Step-by-step explanation:

r = 7(t+3)

expanding the bracket

r = 7t + 21

bringing t to the left hand side

7t = r - 21

divide both sides by seven

t= r-21
