What is the slope of the line that is represented by the equation y−15=−6(x+7)?
masya89 [10]

Answer:

slope = - 6

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

y - 15 = - 6(x + 7) ← is in point- slope form

with slope m = - 6

Y'all can you answer these? 8th grade algebra 1-10 Q's??
Oxana [17]

Answer:

1. slope= 3/4x Y-intercept= 7

2. slope= 5x Y-intercept=8

3. slope= -2x Y-intercept=0

4. slope= 0 Y-intercept=12

*the table ones are difficult to type out but sorry if it doesnt make sense*

5. X Y=3x+4. Y

0 y=3(0)+4 4

1 y=3(1)+4 7

2 y=3(2)+4 10

3 y=3(3)+4 13

4 y=3(4)+4 16

6. X y=1/2x-1. Y

-2 y=1/2(-2)-1 -2

1 y=1/2(1)-1 1.5

4 y=1/2(4)-1 2

6 y=1/2(6)-1 3

9 y=1/2(9)-1 3.5

7. X. Y=5-2x Y

0 y=5-2(0) 5

1 y=5-2(1) 3

2 y=5-2(2) 1

3 y=5-2(3) -1

4 y=5-2(4) -3

I believe you need the graph for the last 3

If g(x) = 2x – 5, then evaluate g(2x2 – 3)<br><br> please explain.
Juliette [100K]
2(2x^2-3) -5
4x^2 - 6 - 5
4x^2 - 11

g(x) = 2x - 5
If you had to evaluate g(3)
You would substitute 3 in for the x and simplify. Instead of substituting a single number you are substituting the binomial
2x^2 -3 and then simplifying. I hope you understand.

A man is painting a building that is 20 meters high. He leans able 12 meter ladder against the building. The ladder is 5 meters
telo118 [61]

Answer:

The approximate height of man if he is standing on the top of leaning ladder will be 13 m.

Step-by-step explanation:

Distance from bottom of building to the point where ladder touches the wall = p

Length of the ladder = h = 12 m

Distance of ladder from the bottom of the building = b = 5 m

\cos \theta =\frac{b}{h}=\frac{5 m}{12 m}

\theta =65.38^o

\sin \theta=\frac{p}{h}=\frac{p}{12 m}

p=12 m\times \sin (65.38^o)=12m\times 0.9090=10.908 m

Height of the man ,x= 1.87 m

Height of man if he is standing on the top of leaning ladder = p+ x

=10.908 m+ 1.87 m = 12.778 m ≈ 13 m
