Answer:

Step-by-step explanation:

Let the smallest integer be x. The integers will be x, x+1, x+2, all the way up to x+6.

119 = 7x + (1+2+3+4+5+6)

119 = 7x + 21

7x = 98

x = 14

The second smallest integer will be x+1, so x+1 = 15.

12x-3y=3<br> y=4x-1 please help solve this equation

Paraphin [41]

12x-3y=3
y=4x-1

12x-3(4x-1)=3
12x-12x-3=3
24x=6
x=4

y=4(4)-1
y=15

x=4; y=15

Solving a Quadratic Equation by Completing the Square Solve x2 + 8x = 33 by completing the square. Which is the solution set of

tresset_1 [31]

Divide the coefficient of x by 2 then square the quotient.
Add the result to both sides of the equation.

$x^2 + 8x = 33$
$x^2 + 8x + (\frac{8}{2})^2 = 33 + (\frac{8}{2})^2$
$x^2 + 8x + 4^2 = 33 + 4^2$
$x^2 + 8x + 16 = 33 + 16$
$x^2 + 8x + 16 = 49$

Factor the left-hand side.

$(x + 4)^2 = 49$

Square both sides.

$x + 4 = \sqrt{49}$

Subtract both sides by 4.

$x = -4$ $± \sqrt{49}$

Simplify.

$x = -4$ $± 7$
So, x can either equal -4 + 7 or -4 - 7

So, the answer is {-11, 3}

NOTE: You're probably seeing a strange A in the equations. I tried to fix it, but I couldn't. Sorry about that.

WILL MARK BRAINLYEST AND 50 POINTS

True [87]

D would be the correct answer because you can use a variable (in this case they used D) in order to represent an unknown number. Because of this, you would be subtracting five from an unknown number (d). Hope this helps!
