Answer:

B) -5, 5, -7, 7

Step-by-step explanation:

3x² - bx + 2

factor:

(3x - 2 )(x - 1) = 3x² - (5)x + 2 so 5 does work

(3x - 1 )(x - 2) = 3x² - (7)x + 2 so 7 does work

(3x + 2 )(x + 1) = 3x² + 5x +2 = 3x² - (-5)x + 2 so -5 does work

(3x + 1 )(x + 2) = 3x² + 7x + 2 = 3x² - (-7)x + 2 so -7 does work

Provide me three coordinate points for the following, given the Slope and Y-intercept. 5. Slope = 7/9, Y intercept = 12(give me

madam [21]

Since we have that the slope is m = 7/9 and the y-intercept is b = 12, we can write the equation of the line in slope-intercept form:

$\begin{gathered} y=mx+b \\ \Rightarrow y=\frac{7}{9}x+12 \end{gathered}$

to find three coordinate points, we can use arbitrary values on x to get the y-coordinate. To make things easier, let's use x = 9, 18 and 27:

$\begin{gathered} x=9 \\ \Rightarrow y=\frac{7}{9}(9)+12=7+12=19 \\ x=18 \\ \Rightarrow y=\frac{7}{9}(18)+12=7(2)+12=14+12=26 \\ x=27 \\ \Rightarrow y=\frac{7}{9}(27)+12=7(3)+12=21+12=33 \end{gathered}$

therefore, the line with slope m = 7/9 and y-intercept 12 passes through the three points (9,19), (18,26) and (27,33)

Help me please!!!!!!!

Answer:

Step-by-step explanation:

The explanation in option choice C is better than what I can give, but the triangles are similar, meaning they either share angles or side lengths, not congruent, where they have to share both.

Answer:

Step-by-step explanation:

5x + 2y = - 2
