The equations x + 5 y = 10, 3 x minus y = 1, x minus 5 y = 10, and 3 x + y = 1 are shown on the graph below. On a coordinate pla

ne, there are 4 lines. Green line goes through (0, negative 1) and (1, 2). Blue line goes through (0, 1) and (1, negative 2). Pink line goes through (0, 2), and (2, 1.5). Orange line goes through (negative 2, negative 2.5) and (2, negative 1.5). Which is the approximate solution for the system of equations x + 5 y = 10 and 3 x + y = 1?

Answer:

<em>Answer is </em><em>given below with explanations</em><em>.</em>

Step-by-step explanation:

Answer is option 1) 85 : 51

given \: that \:  \\ triangle \: SPT \: is \: similar \: to \: triangle \:  QPR \\ corresponding \: sides \: of \: similar \:  \\ triangles \: are \: in \: proportion \\ then \:  \\  \frac{SP}{ QP}  =  \frac{PT }{ PR}  \\  \frac{3x}{3x + 24}  =  \frac{51}{85}  \\ taking \: reciprocal \: on \: both \: sides \\  \frac{3x + 24}{3x}  =  \frac{85}{51}

Option 1 is correct.

What number needs to be added to 5 and 3 so that the ratio of the first number to the second becomes 3:2?
sukhopar [10]

Answer:

7

Step-by-step explanation:

x + 3 : x + 8 : : 2 : 3

(x + 3) \times 3 = (x + 8) \times 2 \\ 3x + 9 = 2x + 16 \\ 3x - 2x = 16 - 9 \\ x = 7 \\ x + 3 = 7 + 3 = 10 \\ x + 8 = 7 + 8 = 15 \\  

10 : 15

2 : 3

If g(x) = ax2 + 3x – 5, what does a need to be so that...
Arisa [49]

Answer:

Step-by-step explanation:

g(x)=ax²+3x-5

then g(-1)=-15

therefore g(-1) ⇒ a(-1)²+3(-1)-5=-15

a-3-5=-15

a-8=-15

a=-15+8

a=-7

for g(-1)=-15

then g(x)= -7x²+3x-5
