Answer:

Choice A is correct answer.

Step-by-step explanation:

y = mx+b is slope-intercept for equation of a line where m denotes slope and b denotes y-intercept of a line.

Slope is defined as the steepness of the line and it is denoted by m.

y-intercept is the point where the value of x is zero and it is denoted by any small letter.

Given equation is :

y = -3x+4

comparing above equation with general slope - intercept form , we get

m = -3 and b = 4

hence,y-intercept is 4.

Answer:

A

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 3x + 4 is in this form

with y- intercept c = 4 → A

Is x = -7, the solution to -11 + 2x = -26? Justify your answer in complete sentences.
Natali5045456 [20]
First of all, you can move the +2x to the other side:
-11 = -26 - 2x

Then you can move the -26 to the other side and then simplify:
-11+26 = -2x
 15 = -2x

Then you can divide both sides by 2:
7.5 = -x

Then you can flip the sides and the signs around:
x = -7.5

No, The answer is not -7, it is -7.5
Hope this helps! :)

Please help I don’t understand it’s like angles and stuff picture above.
dusya [7]

Answer:

1) 145°

2) 20°

3) x = 7 ; measurement of the missing angle = 24

Step-by-step explanation:

1) supplement = 180°, 180 - 35 = 145

2) complment = 90° , 90 - 70 = 20

3) the figure is a right angle so the measurement is 90°

66 + (4x-4) = 90

62 + 4x = 90

4x = 28

x = 7

4(7) - 4

28 - 4

= 24

In what ways does adding a constant or coefficient to a quadratic equation affect the graph
lesya692 [45]
A constant can either shift the graph up or down. If coefficient is less than 1 it will make the graph wider, if it's more than 1 it will make graph more narrow
