Answer:

b

Step-by-step explanation:

Justin's score has to be greater than 80. the appropriate inequality sign is >

Note that

> means greater than

< means less than

≥ means greater than or equal to  

≤ less than or equal to  

On the number line, since the score has to be greater than 80, the line would start from 80 and end on 95

> or < is represented by unfilled circle

≤ or ≥  is represented by filled circle

Can someone help me with these please?
saul85 [17]

Point-slope form: y-y1 = m(x-x1)

Standard form: ax + by = c

Slope-intercept form: y = mx+b


Start by finding the slope. We know it is negative since the line is decreasing. The slope is -4/3.


To create point-slope form, we need to get one point from the graph. Let's use (3,0).

y = -\frac{4}{3}(x-3)


To create slope-intercept form, we need the slope and the y-intercept. The y-intercept is the point where our equation crosses the y-axis. For this equation, it is 4.

y = -\frac{4}{3}x + 4


To get standard form, solve the equation in terms of C.


Point-slope form: y = -4/3(x-3)

Slope-intercept form: y = -4/3x + 4

Standard form: 4/3x + y = 4

Solve the equation. 9+2 14x – 31 = 19<br> Please answer it step by step
siniylev [52]

Answer:

x =  \frac{41}{28}  = 1 \frac{13}{28}

Step-by-step explanation:

9 + 2(14x - 3) = 19

9 + 28x - 31 = 19

- 22 + 28x = 19

28x = 19 + 22

28x = 41

\boxed{\green{x =  \frac{41}{28}  = 1 \frac{13}{28}}}
