Find the value of X or Y so that the line through the points has the given slope. (X, 0) and (4,1); slope: 1/5

Ronch [10]

Point slope formula:
(y₂ -y₁) = m(x₂ - x₁)
(1 - 0) = $\frac{1}{5}$ (4 - X)
1 = $\frac{4}{5} - \frac{1}{5} X$
$\frac{1}{5} = -\frac{1}{5} X$

-1 = X

Given that f(x) = x2 + 10x + 21 and g(x) = x + 7, find (f•g)(x) and express

sammy [17]

Answer:

Step-by-step explanation:

$given \\ f(x) = x ^{2} + 10x + 21 \: and \: g(x) = x + 7$

$as \: we \: know \: (f.g)x \: is \: same \: as$

$f(g(x))$

$so \:$

$f(x + 7) = ( x + 7) ^{2} + 10(x + 7) + 21$

$f(x + 7) = {x}^{2} + 14x + 49 + 10x + 70 + 21$

$f(x + 7) = x^{2} + 24x + 140$

$therefore$

$(f.g)x = {x}^{2} + 24x + 140$
