SOS NEED HELP NOW WILL GIVE BRAINLYEST Identify the slope y=-1/2x+4

Mathematics
1 answer:
pantera1 [17]3 years ago
4 0

Answer: slope, m = -1/2(coefficient of x in the equation

Step-by-step explanation:

y=-1/2x+4

We will compare the equation with the slope intercept equation ,

y = mx + c

Where y is the dependent variable

m is the slope

x is the independent variable

c is the intercept. This is where the line on the graph cuts the y axis

For y=-1/2x+4,

the intercept ,c is 4

Slope = m =-1/2

-1/2 is a negative slope because negative sign. This means the plotted line moves from up to down

Given the triangle below, what is m<br> A. 46.2<br> B. 41.40<br> C. 48.4<br> D. 38.6°
Brrunno [24]

Answer:

B 41.4

Step-by-step explanation:

complete Pythagoras for general triangles :

c² = a² + b² - 2ab×cos(C)

with "c" being the side opposite of the angle C.

=>

8² = 10² + 12² - 2×10×12×cos(C)

64 = 244 - 240×cos(C)

240×cos(C) = 244 - 64 = 180

cos(C) = 180/240 = 18/24 = 3/4 = 0.75

C = 41.40962211... ≈ 41.4

How to do question 5 and 6. Can you explain the first one which is A for 5 and 6?<br><br>Thank you​
Illusion [34]

for 6

in a

given

slope(m)=1

point=(2,-4)=(x1,y1)

we know

equation of straight line

y-y1=m(x-x1)

y+4=1(x-2)

y+4=x-2

therefore x-y-6=0 is the required equation

substituting with ax+by+c=0 we get

a=1

b= -1

c= -6

10x+9=4x -9 solve <br><br> please help
Neporo4naja [7]

Answer:

x = -3

Step-by-step explanation:

To solve this, you need to isolate the variable x, this means only one side of the equation should have the variable x. To do this, you need to do the opposite operation from what's given (if it's addition, use subraction; if it's multiplication, use division; these work vise versa)

  • Subtract 9 from both sides of the equation. This gives you 10x = 4x - 18.
  • Subtract 4x from both sides of the equation. This gives you 6x = -18.
  • Divide both sides by 6. This gives you x = -3

The final answer is x = -3
