What has a graph that passes through the point (-4,2) and has a slope of 9/2?

1 answer:

5 0

By using the equation y-y1=m (x-x1) you can plug in your coordinates(2 into y1,-4into x1) and your slope (9/2 in for m) you get your equation y-2=9/2 (x+4) this is the equation of a line that has a slope of 9/22nd and passes through the point (-4,2)

Answer:

F. x ≤ -5

Step-by-step explanation:

Translating the diagram to more conventional symbols, we have ...

4x +12 ≤ -8

4x ≤ -20 . . . . . . . subtract 12 from both sides

x ≤ -5 . . . . . . . . . divide both sides by 5

E is between D and F. Solve for each segmant length

Julli [10]

Answer:

DE = 32

EF = 34

Step-by-step explanation:

3x + 5 + 4x - 2 = 66

7x + 3 = 66

7x = 63

x = 9

DE = 3(9)+5 = 32

EF = 4(9)-2 = 34

check: 32 + 34 = 66

If mZDEC = (12x - 3), mZBCE =

kati45 [8]

Answer:

Step-by-step explanation:

12x - 3 = 180 - (7x - 26) supplementary angles

19x = 209

x = 11

m∠DEC = 12(11) - 3 = 129°

m∠BCE = 7(11) - 26 = 51°

M∠ADE = 129 - 72 = 57° exterior angle rule

m∠EDB = 180 - 57 = 123° supplementary angles

m∠DBC = 57° corresponding angle to ADE

Problem Solving<br> Find the exact solution of each equation for 0 < theta < 2 pi

horrorfan [7]

Answer:

C) $\theta=\frac{\pi}{4},\frac{3\pi}{4},\frac{5\pi}{4},\frac{7\pi}{4}$

Step-by-step explanation:

$sin^2\theta=\frac{1}{2},\: 0\leq\theta\leq2\pi\\ \\\frac{1-cos(2\theta)}{2}=\frac{1}{2}\\ \\1-cos(2\theta)=1\\\\cos(2\theta)=0\\\\2\theta=\frac{\pi}{2}+\pi n\\ \\\theta=\frac{\pi}{4}+\frac{\pi}{2}n\\ \\ \theta=\frac{\pi}{4},\frac{3\pi}{4},\frac{5\pi}{4},\frac{7\pi}{4}$

Recall the identity $sin^2\theta=\frac{1-cos(2\theta)}{2}$
