Answer:

b = 2

Step-by-step explanation:

3b + 2(b - 3) = 4

--distributive property-- 2(b - 3) = 2b - 6

3b + 2b - 6 = 4

(add like terms)

5b - 6 = 4

(add 6 to both sides)

5b = 10

(divide both sides by 5 to get b alone)

b = 2

The equation line l is given by the equation y= 7/4x+3. line m goes through the point ( –1,4) and is perpendicular to line l whi

mr_godi [17]

We determine line m as follows:

*First, by theorem we have the following:

$m_1=-\frac{1}{m_2}$

Here m1 & m2 are the slopes of two perpendicular lines. For all lines that are perpendicular that is true, so we calculate the slope of line m using the slope of the function given [Which has a slope of 7/4]:

$m_1=-\frac{1}{\frac{7}{4}}\Rightarrow m_1=-\frac{4}{7}$

So, the slope of line m is -4/7. Now, using this slope and the point (-1, 4) we replace in the following expression:

$y-y_1=m_1(x-x_1)$

Here x1, y1 & m1 are the x-component of the point, the y-component of the point, and the slope of the line respectively, so we replace and solve for y:

$y-4=-\frac{4}{7}(x-(-1))\Rightarrow y-4=-\frac{4}{7}x-\frac{4}{7}$ $\Rightarrow y=-\frac{4}{7}x+\frac{24}{7}$

And that last function of y is the line m.

Marcus rode his bike 60 miles in 4 hours. Marcus thinks that in order to find the unit rate, he should determine how far he rode

ELEN [110]

Answer:

No, he is not correct

Step-by-step explanation:

To find the unit rate you need to .60 by 4. you will get 2.4, which is the

unit rate. he rides his bike 2.4 mph.

triangle ABC is reflected about the line Y equals negative X to give triangle ABC with vertices A (-1, 1), B (-2, -1), C (-1,0).

Amiraneli [1.4K]

9514 1404 393

Answer:

A'(-1, 1)
B'(1, 2)
C'(0, 1)

Step-by-step explanation:

Reflection across the line y = -x is accomplished by the transformation ...

(x, y) ⇒ (-y, -x)

Then the images of the given points are ...

A(-1, 1) ⇒ A'(-1, 1) . . . . this point is on the line of reflection, so doesn't move

B(-2, -1) ⇒ B'(1, 2)

C(-1, 0) ⇒ C'(0, 1)
