The GCF is the Greatest Common Factor, which means that it is the highest number that divides exactly into two (or more) numbers, in this case 55 and 100. You start off by listing all of the factors of both numbers. When you have finished, you find the highest factor that goes into them both, and that is the answer.

1, 5, 11, 55.
1, 2, 4, 5, 10, 20, 25, 50, 100.

As you can see, the highest number that goes into them both is 5. Therefore, the GCF of 55 and 100 is 5.

If f(x) = 4x + 3x2 + 1, then what is the remainder when f(x)<br> is divided by X -2?

Bezzdna [24]

Answer:

remainder = 21

Step-by-step explanation:

If f(x) is divided by (x - h) then the remainder is f(h)

Here f(x) is divided by (x - 2) with h = 2 , then remainder is

f(2) = 4(2) + 3(2)² + 1 = 8 + 3(4) + 1 = 8 + 12 + 1 = 21

3. if kx² + 2x + k = -kx have equal roots, find the values of k.<br>

crimeas [40]

Answer:

k = - $\frac{2}{3}$ , k = 2

Step-by-step explanation:

Using the discriminant Δ = b² - 4ac

The condition for equal roots is b² - 4ac = 0

Given

kx² + 2x + k = - kx ( add kx to both sides )

kx² + 2x + kx + k = 0 , that is

kx² + (2 + k)x + k = 0 ← in standard form

with a = k, b = 2 + k and c = k , thus

(2 + k)² - 4k² = 0 ← expand and simplify left side

4 + 4k + k² - 4k² = 0

- 3k² + 4k + 4 = 0 ( multiply through by - 1 )

3k² - 4k - 4 = 0 ← in standard form

(3k + 2)(k - 2) = 0 ← in factored form

Equate each factor to zero and solve for k

3k + 2 = 0 ⇒ 3k = - 2 ⇒ k = - $\frac{2}{3}$

k - 2 = 0 ⇒ k = 2

Please help I’m vvv confused

Triss [41]

Equation is y=kx. We have four chance to figure out k; hopefully they all give the same result

x=9, y=63, y=kx becomes 63=k(9) so k=63/9=7

x=4, y=28, 28=k(4), k=7

The constant of proportionality is 7; we check 2×7=14, 11×7=77

Answer: k=7, y=7x

Two cyclists start from the same point at the same time and move in opposite directions. One cyclist is traveling at 7 mph, and

ivolga24 [154]

Answer:

d = 4 miles

Step-by-step explanation:

combined speed = 7 + 9 = 16 mph

s = d/t

d = st

d = 16 miles/hr × 0.25 hr

d = 4 miles
