kkurt [141]
First plug in the numbers: 3x6+4x12/2. then do the Pemdas, so multiplication first: 18+42/2. then since the division is like a fraction bar, it means to divide but first simplify the 18+42: 60/2. Your answer is 30.

In the xy-plane, line l has a y-intercept of -13 and is perpendicular to the line with the equation y=-2/3x. If the point (10, b
AlekseyPX

Answer:

The value of b is 2.

Step-by-step explanation:

The standard form of the equation of the line is of the form:

y = m\cdot x + k

Where:

x, y - Independent and dependent variable, dimensionless.

m - Slope, dimensionless.

k - y-intercept, dimensionless.

Given that line l is perpendicular to y = -\frac{2}{3}\cdot y, the slope is equal to:

m = -\frac{1}{m_{\perp}}

Where m_{\perp} is the slope of the perpendicular line, dimensionless.

If m_{\perp} = -\frac{2}{3}, then:

m = -\frac{1}{\left(-\frac{2}{3}\right) }

m = \frac{3}{2}

If x = 0 and y = -13, the y-intercept of the line l is:

-13 = \frac{3}{2}\cdot (0) +k

k = -13

The equation of the line l is y = \frac{3}{2}\cdot x -13. Given that y = b and x = 10, the value of b is:

b = \frac{3}{2}\cdot (10)-13

b = 15-13

b = 2

The value of b is 2.
