Well when you do a problem and it's multiplication and you have to us your math skills and then when you get it wrong don't that

mean that it do not work and you need to us another skill to answer your question.

Not necessarily. You could have done your multiplication wrong. Or in some cases, yes, you could have to use another skill. For example, you can't solve an optimization problem with addition, you need some calculus skills under your belt.

Los puntos de intersección de los gráficos de f(x)=x2+6x−7 y g(x)=4x−10
alisha [4.7K]

Answer:

Those graphs do not intersect.

Estes gráficos no se intersecciónan

Step-by-step explanation:

The intersection points are x for which:

f(x) = g(x)

In this question:

f(x) = x^{2} + 6x - 7

g(x) = 4x - 10

So

x^{2} + 6x - 7 = 4x - 10

x^{2} + 2x + 3 = 0

Solving a quadratic equation:

Given a second order polynomial expressed by the following equation:

ax^{2} + bx + c, a\neq0.

This polynomial has roots x_{1}, x_{2} such that ax^{2} + bx + c = a(x - x_{1})*(x - x_{2}), given by the following formulas:

x_{1} = \frac{-b + \sqrt{\bigtriangleup}}{2*a}

x_{2} = \frac{-b - \sqrt{\bigtriangleup}}{2*a}

\bigtriangleup = b^{2} - 4ac

In this question:

x^{2} + 2x + 3 = 0

So a = 1, b = 2, c = 3

\bigtriangleup = b^{2} - 4ac = 2^{2} - 4*1*3 = -8

Sincce \bigtriangleup is negative, there are no solutions, which means that those graphs do not intersect.

A paint mixes green and white paint in the ratio 13:50. 4 litres of white paint are used. How much green is used? please help me
wlad13 [49]

Answer:

1.04 liters

Step-by-step explanation:

If 50 is 4liters

Then 13 is x

Use this below equation

Value t is for value y then how much for value z

x =  \frac{t}{y}  \times z

X = 4/50 *13

X = 1.04liters

Or

13/50 = x/4 (cross multiply)

50X = 52

X = 52/50

X = 1.04 liters
