Two consecutive integers are such that 7 times the biggest and then added to the smallest equals

Arturiano [62]

Answer:

61,62

Step-by-step explanation:

Let the smallest number be x

Hence, the biggest number = x+1 [as it consecutive]

Hence,

7(x+1)+x=495

7x+7+x+495

8x=495-7

8x=488

x=61

Hence, smaller number=61, bigger number=62

find the equation of the axis of symmetry for this equation. f(x) = 6x^2 - 3x + 49. hint: to find the axis of symmetry, use equa

Olenka [21]

We want to find the axis of symmetry of the function;

$f(x)=6x^2-3x+49$

STEP 1:

The equation for the axis of symmetry of a line is given as;

$x=-\frac{b}{2a}$

From the equation, a = 6 and b = -3, so,

STEP 2: Insert the values of a and b into the equation to obtain;

$x=-\frac{-3}{2\times6}=--\frac{3}{12}=+\frac{1}{4}$

CONCLUSION:

Therefore, we see that the axis of symmetry is the line;

$x=\frac{1}{4}$

Scrat [10]

Answer:

y = 2x - 4

Step-by-step explanation:

Rearrange the given equation to slope-intercept form.

x + 2y = 2

2y = -x + 2

y = -1/2x + 1

The slope of the given line is -1/2. The slope of a perpendicular line will be the negative inverse, meaning that the slope will be 2.

-1/2 = 2

Find the equation of the new line with the point-slope form using the new slope and given point.

y - y₁ = m(x - x₁)

y - 6 = 2(x - 5)

y - 6 = 2x - 10

y = 2x - 4

The equation will be y = 2x - 4.

Can someone help me on this ? its Algebra 1 on exponents

Svetradugi [14.3K]

The volume of a rectangular prism is its length times width times height, or algebraically, $V=lwh$ . You may be used to computing volume with numbers, but remember, a variable is a stand-in for a number. So you can solve this in the same way. Substitute $l=x, w= \frac{x}{2},h= \frac{x}{3}$ into the formula for volume. You get $(x)( \frac{x}{2})( \frac{x}{3} )$ , and you multiply these factors together. As you would with ordinary fractions, multiply the numerators and denominators across. You get $\frac{(x)(x)(x)}{(1)(2)(3)} = \frac{x^3}{6}$ . It seems that the book wants you to simplify by bringing the 6 up to the denominator. Recall the rule $x^{-n}= \frac{1}{x^n}$ , if n is non-negative. The opposite applies so that $\frac{1}{6} = 6^{-1}$ . For your final answer, you write $6^{-1}x^3$ . This corresponds to answer choice B.
