When you write an equation in the slope-intercept form

$y=mx+b$

the two coefficients m and b represent, respectively, the slope and the intercept.

So, in your case, m=1/4 and b= -7, which leads to the equation

$y=\dfrac{1}{4}x-7$

PLZZZ HURRYYY!!Which graph best represents the solution to the system of equations shown below? y = -4x + 19 y = 2x + 1 A coordi

elena-s [515]

Answer:

Two lines are shown intersecting on ordered pair 3, 7.

Step-by-step explanation:

The first of the two lines has a slope of -4 and a y-intercept of 19 (off the top of the graph). It will decrease 4 units for each 1 unit to the right.

The second of the two lines has a slope of +2 and a y-intercept of +1. It will increase 2 units for each 1 unit to the right.

These two lines must intersect in the first quadrant at a point with an x-value less than 5, eliminating the first and last two choices, leaving only the second choice you have listed here.

You would have to examine the graphs to see which has the lines with proper slope and intercept.

My graphing calculator's solution is attached.

Can someone help me with this!

Answer:

2. x = 18

3. x = 7

4. missing angles are 73°

Step-by-step explanation:

The simple rules involved here are ...

the sum of angles of a triangle is 180°
angles forming a linear pair are supplementary (total 180°).

Together, these tell you that the external angle of a triangle has the same measure as the sum of the opposite internal angles. (The third angle is the supplement of the external angle.)

Problem 1

Work shown is correct.

Problem 2

Using the above observation, ...

(5x -11)° + (2x +20°) = (11x -63)°

7x +9 = 11x -63 . . . . . collect terms, divide by °

72 = 4x . . . . . . . . . . . add 63-7x

18 = x

Problem 3

The angles of an equilateral triangle are 60°, so that is the measure of the marked angle.

9x -3 = 60

9x = 63 . . . . . . add 3

x = 7 . . . . . . . . .divide by 9

Problem 4

You don't need to find the value of x to answer this question. The base angle of an isosceles triangle is the complement of half the apex angle. This comes from the fact that the two base angles are equal measure.

(apex angle) + 2(base angle) = 180° . . . . sum of angles in isosceles triangle

(1/2)(apex angle) +(base angle) = 90° . . . divide by 2

base angle = 90° -(1/2)(apex angle) . . . . .solve for base angle

Filling in the given apex angle value, we get ...

base angle = 90° -(1/2)(34°) = 73°

Both missing angles are 73°.
