lesya [120]

Answer:

Step-by-step explanation:

We can find y-intercept by substituting 0 for x in the equation.

So, we will have:

y=2*5^0+4=2*1+4=2+4=6

y intercept is 6

Through (-4,3) , perpendicular to m=-2/3

stiv31 [10]

Answer:

The equation of the line:

$y=\frac{3}{2}x+9$

Step-by-step explanation:

Given

The point (-4, 3)

m = -2/3

We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:

slope = m = -2/3

perpendicular to m = -1/m

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

Using the point-slope form of the line equation

$y-y_1=m\left(x-x_1\right)$

substituting the values m = 3/2 and the point (-4, 3)

$y-3=\frac{3}{2}\left(x-\left(-4\right)\right)$

$y-3=\frac{3}{2}\left(x+4\right)$

Add 3 to both sides

$y-3+3=\frac{3}{2}\left(x+4\right)+3$

$y=\frac{3}{2}x+9$

Thus, the equation of the line:

$y=\frac{3}{2}x+9$

F(x)=22xplus 33 and g(x)=x2−44x−55, find (g◦f)(88)

Law Incorporation [45]

F(x) = 22x + 33
g(x) = x² - 44x - 55
(g о f)(88) = (22(88) + 33)² - 44(22(88) + 33) - 55
(g о f)(88) = (1936 + 33)² - 44(1936 + 33) - 55
(g о f)(88) = (1969)² - 44(1969) - 55
(g о f)(88) = 3,876,961 - 86,636 - 55
(g о f)(88) = 2,790,325 - 55
(g о f)(88) = 3,790,270
