Step-by-step explanation:

Answer:

The graph will have opposite x-intercepts of b and –b and be symmetrical about the y-axis. The graph will have a y-intercept at –b2.

Step-by-step explanation:

i don't have the step by step explanation but that answer is also right

the x intercepts are b and b

the graph has opposite x intercepts

the graph is symetrical over the y axis

the y intercept is at b²

Answer:

f(x) ≤ x2 – x – 1

If he = 7x -27 find the value of x

Amiraneli [1.4K]

$\\ \sf\longmapsto 7x-27=1$

$\\ \sf\longmapsto 7x=1+27$

$\\ \sf\longmapsto 7x=28$

$\\ \sf\longmapsto x=\dfrac{28}{7}$

$\\ \sf\longmapsto x=4$

An integer from 300 through 780, inclusive is to be chosen at random, find the probability that the number is chosen will have 1

exis [7]

Answer:

93/481

Step-by-step explanation:

Total number of integers from 300 through 780, inclusive:

780 - 299 = 481

Number of integers with at least one of digit 1:

Hundreds - 0,
Tens - 5*10 = 50 (31th, 41th, 51th, 61th, 71th)
Units - 4*9 + 7 = 43 (300 till 699 and 700 till 780)
So in total 50 + 43 = 93

The probability is:

P = favorable outcomes/total outcomes = 93/481

Lauren has a points card for a movie theater.

Lesechka [4]

Multiply points per visit x number of visits, using x for the number of visits:

5.5x

Add that to the points she already has:

5.5x + 60

This needs to equal a total of 104 points:

5.5x + 60 = 104

Now solve for x

5.5x + 60 = 104

Subtract 60 from both sides

5.5x = 44

Divide both sides by 5.5

X = 8

She needs 8 more visits
