x + 42° + 58° = 180°

x + 100° = 180°

x = 180° - 100°

x = 80°

Dajuan is painting a mural on a rectangular
horsena [70]

Answer:

Every day Dajuan will paint 14.5 square feet of the wall.

Step-by-step explanation:

Since Dajuan is painting a mural on a rectangular wall, which measures 14.5 feet long and 10 feet wide, and so far, his mural covers 60% of the wall, and Dajuan will paint the remaining part of the wall over the next four days, painting the same amount of the wall, in square feet, on each of those four days, to determine how much of the wall, in square feet, will Dajuan paint on each of the next four days, the following calculation must be performed:

((14.5 x 10) x 0.4) / 4 = X

(145 x 0.4) / 4 = X

58/4 = X

14.5 = X

Therefore, every day Dajuan will paint 14.5 square feet of the wall.

Given the quadratic function f(x) = (x + 6)(x – 3):
Harlamova29_29 [7]

Answer:

Step-by-step explanation:

Given quadratic function is,

f(x) = (x + 6)(x - 3)

For x-intercept,

Substitute the value f(x) = 0.

(x + 6)(x - 3 = 0

x = 3, -6

So the x-intercepts will be,

(-6, 0) and (3, 0)

For y-intercept,

Substitute the value for x = 0,

f(0) = (0 + 6)(0 - 3)

     = -18

Therefore, y-intercept of the given quadratic function will be (0, -18).

3. Write an equation for the line perpendicular to y = 6x - 5 that contains (2, 10)
Artemon [7]

<u>Answer:</u>

y = -\frac{1}{6}x +\frac{31}{3}

<u>Step-by-step explanation:</u>

We are to find the equation for the line which is perpendicular to another line with the equation y = 6x - 5 and passes through a point (2, 10).

Since the slope of a line which is perpendicular to another line is the negative reciprocal of the other line, therefore the slope of our line will be -\frac{1}{6}.

Finding the y-intercept:

y=mx+c

10=-\frac{1}{6} (2)+c

c=\frac{31}{3}

Therefore, the equation of the line will be y = -\frac{1}{6}x +\frac{31}{3}.
