Integer means whole number, so the root of 5 is 2.23 which would round to 2. 18 = 4
10 = 3

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

Len [333]

Step-by-step explanation:

the point-slope form is

y - y1 = m(x - x1)

with (x1, y1) being a point on the line.

so, we have here

y - 4 = 0×(x - -4) = 0

therefore, the resulting equation (which is automatically in slope-intercept form) is

y = 4

this is a flat, horizontal line that passes through (0, 4) on the y-axis, and of course, through (-4, 4), as the y value is 4 for every possible value of x.

Mark all true statements. Group of answer choices

laiz [17]

Answer:

True

False

Step-by-step explanation:

a) The first statement is the basis for Euclid's algorithm to compute the gcd of two nonnegative integers a,b. You can prove this as follows.

Let G=gcd(a,b). Since r=a-bq and G divides a and G divides b, then G divides r. Now, G divides a and G divides r, hence G divides gcd(b,r).

On the other hand, since a=bq+r, and gcd(b,r) divides b and r, then gcd(b,r) divides a. Therefore gcd(b,r) divides a and b, which implies that gcd(b,r) divides G.

x divides y and y divides x implies that |x|=|y|. The GCD's are nonnegative, therefore G=gcd(b,r).

b) It is false. In general, to test for primality of N, you have to check that all primes smaller than N do not divide N. In this case, we have to check for 2,3,5,7,11,13,17,19,23,...

101 is prime, but this may be false in general. For example, consider N=13*11=143. N is not prime, and n is not divisible by 2,3,5, or 7.

Helppp meee plssss

Answer:

Cost of fish = Php. 60, amount of fish = x kg
Cost of chicken = Php. 120, amount of chicken = y kg
Budget = at most Php. 1200

a) Required inequality (not a system as only one condition is given):

60x + 120y ≤ 1200

Simplified:

x + 2y ≤ 20

The graph is attached

b) Verify ordered pair (10, 7):

10 + 2*7 ≤ 20
24 ≤ 20

False inequality, so this pair is out of solution set
