Answer: 5/24

Step-by-step explanation:

The problem is 7/12-3/8. I got a common denominator of 24, then multipled 8 and 3 by 3, and 7 and 12 by 2. The problem is now 14/25-9/24, which equals 5/24

the axis of symmetry of a quadratic equation is x = –3. if one of the zeroes of the equation is 4, what is the other zero?

FinnZ [79.3K]

ANSWER

The other zero is

$x = - 10$

EXPLANATION

The axis of symmetry serves as the midpoint of the two zeroes.

We were given that the axis of symmetry of the quadratic equation is
$x = - 3$

We were also given that, one of the zeroes of the quadratic equation is
$x = 4$

Let the other zero of the quadratic equation be
$x = p$

,then, we apply the midpoint formula to find the value of
$p$

Since it is the x-values of the intercepts that gives the solution, we use only the x-value part of the midpoint formula which is given by,

$\frac{x_1 + x_2}{2} = axis \: of \: symmetry$

We substitute to obtain,

$\frac{p + 4}{2} = - 3$

We multiply through by 2 to get,

$p + 4 = - 6$

This implies that,

$p = - 6 - 4$

$p = - 10$

Please answer this question..........

In order to find the y-intercept, replace x by 0.

So, for first option:
f(0) = 7(1) - 2 = 5

For second option:
f(0) = -3(1) - 5 = -8

For third option:
f(0) = 5(1)-1=4

For Fourth option:
f(0) = -5(1) + 10 = 5

For Fifth Option:
f(0) = 2(1) + 5 = 7

So, option 1 and 4 have the y-intercept (0,5)

Which binomial is a factor of 9x2 – 64?

worty [1.4K]

This is a differnce of 2 perfect squares
a²-b²=(a-b)(a+b)
so
9x²-64=(3x)²-(8)²=(3x-8)(3x+8)
factors are (3x-8) and (3x+8)

It cost 17.50 to get into the fair and then cost $8.75 for every ride. I go on . I spent a total of $131.25. Write an equation a

gregori [183]

Answer:

131.25= 17.50+8.75x is the equation

Step-by-step explanation:

solve it to find x

131.25=17.50+8.75x

(subtract 17.50 from both sides)

113.75=8.75x

(divide both sides by 8.75)

13=x
