Answer:

x\geq 12

x is greater than or equal to 12

Step-by-step explanation:

We first start off with recognizing that this is an <u>inequality</u>, and that the answer choices involve <u>solving for </u>x.

I suggest that you write out the steps <em>one-by-one</em> and don't skip any so that making a mistake is less likely.

<u>Rewrite the original equation:</u>

-\frac{3}{4}x + 2 \leq -7

<u>Use reverse PEMDAS (Parentheses, Exponents, Multiplication/Division, Addition/Subtraction) order to isolate </u>x:

Subtract 2 from both sides: -\frac{3}{4} x \leq -9

Divide both sides by -\frac{3}{4} (this flips the inequality symbol since we're dividing by a negative number): x\geq 12

Your final answer is:

x \geq  12

x is greater than or equal to 12

If you want to do any <u>further reading</u> on this topic, search up videos and other helpful resources by putting, "Solving Inequalities" into your preferred search engine.

What is the vertex form, f(x) = a(x − h)2 + k, for a parabola that passes through the point (1, −7) and has (2, 3) as its vertex
kondaur [170]

Answer:

Vertex form: f(x) = -10(x − 2)^2 + 3

Standard form: y = -10x^2 + 40x - 37

Step-by-step explanation:

h and k are the vertex coordinates

Substitute them in the vertex form equation:

f(x) = a(x − 2)^2 + 3

Calculate "a" by replacing "f(x)" with -7 and "x" with 1:

-7 = a(1 − 2)^2 + 3

Simplify:

-7 = a(1 − 2)^2 + 3

-7 = a(-1)^2 + 3

-7 = a + 3

-10 = a

Replace a to get the final vertex form equation:

f(x) = -10(x − 2)^2 + 3

Convert to standard form:

y = -10(x − 2)^2 + 3

Expand using binomial theorem:

y = -10(x^2 − 4x + 4) + 3

Simplify:

y = -10x^2 + 40x - 40 + 3

y = -10x^2 + 40x - 37

kondaur [170]
For the girls:

12:30

Simplifying it, we get:

6: 15
2: 5

For the boys:

16:40

Simplifying it, we get:

8:20
4:10
2:5

So yes, the ratios are both the same for boys and girls.
