Use the point-slope formula to write an equation of the line that passes through (1,0) and has a slope of m=-4. Write the answer

Elena L [17]

Answer:

y = -4x-4

Step-by-step explanation:

We need to find an equation of the line that passes through (1,0) and has a slope of m=-4.

The equation of a line is given by :

y = mx+c

Where

m is slope of line

Put all the values,

y = -4x+c

Put x = 1 and y = 0

So,

0 = -4(1)+c

c = -4

So, the required equation is :

y = -4x-4

Answer:

(a) = 60

(b) = 70

Step-by-step explanation:

(a) Sum of all the angles of a triangle is 180

This is an equilateral Triangle

which means all the sides are equal since all the sides are equal that means all the angles are equal

$x + x + x = 180 \\ 3x = 180 \\ x = \frac{180}{3} \\ x = 60$

(b) this is an isosceles triangle with two equal sides that means the two opposite angles are equal

$40 + x + x = 180 \\ 40 + 2x = 180 \\ 2x = 180 - 40 \\ 2x = 140 \\ x = 70$

60x-5=15 Solve for x will mark you

V125BC [204]

Answer: $x=1/3$

Add 5 to both sides

$60x-5+5=15+5\\60x=20$

Divide both sides by 60

$60x/60=20/60\\x=1/3$
