What is the measure of the highlighted angle

Mathematics
1 answer:
IgorLugansk [536]3 years ago
7 0
Angle on a straight line sums up to 180
so
72+x + x+130 = 180
2x = 180-72-130
2x =-22
x= -11

so Angle on the LHS is 61°
while angle on the RHS is 119°

5x - 5 = 5(x+1) need help
bezimeni [28]

Answer:

There are no solutions.

Step-by-step explanation:

5x-5=5(x+1)

5x-5=5x+5

    +5     +5

5x=5x+10    

-5x -5x

0x=10

There are no possible answers.

Hopefully this helps.

The type of equation given below is in point-slope form <br> y=1/2x-5 true or false
kykrilka [37]

Answer:

false

Step-by-step explanation:

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

the equation y = 1/2x - 5 does not follow this therefore the answer is false

the equation y = -1/2x - 5 is instead put in slope intercept form , y = mx + b

Look Down Below For question:
Ray Of Light [21]
The cattle train
speed - 36.5 km/h
time - x h

the passenger train
speed - 29.2 km/h
time - (2.4+x) h

The cattle train caught up to the passenger train so the distance they travelled is the same.
Distance is speed times time.

36.5 \times x=29.2 \times (2.4+x) \\&#10;36.5x=70.08+29.2x \\&#10;36.5x-29.2x=70.08 \\&#10;7.3x=70.08 \\&#10;x=\frac{70.08}{7.3} \\&#10;x=9.6 \\ \\ 2.4+x=2.4+9.6=12

The passenger train travelled for 12 hours before the cattle train caught up.

Graph the linear equation in three plots: -x+2y=11
MariettaO [177]

Answer:

<h2>In the attachment.</h2>

Step-by-step explanation:

Convert the given equation to the form y = mx + b:

-x+2y=11          <em>add x to both sides</em>

2y=x+11          <em>divide both sides by 2</em>

y=\dfrac{1}{2}x+\dfrac{11}{2}

It's a linear function.

We need only two points to plot the graph. Select any two x values, insert into the equation and calculate y values.

for x = 1

y=\dfrac{1}{2}(1)+\dfrac{11}{2}=\dfrac{1}{2}+\dfrac{11}{2}=\dfrac{12}{2}=6\to(1,\ 6)

for x = -5

y=\dfrac{1}{2}(-5)+\dfrac{11}{2}=-\dfrac{5}{2}+\dfrac{11}{2}=\dfrac{6}{2}=3\to(-5,\ 3)
