False, because a^2+b^2=c^2 and no matter what numbers substitute for which ever variable the answer isn’t going to be true

determine the maximum or minimum of the quadratic function. express your answer in the form (x,y) and using decimals rounded to

kolezko [41]

We are given the following quadratic equation

$f(x)=2x^2+7x-10$

The vertex is the maximum/minimum point of the quadratic equation.

The x-coordinate of the vertex is given by

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

Comparing the given equation with the general form of the quadratic equation, the coefficients are

a = 2

b = 7

c = -10

$h=-\frac{b}{2a}=-\frac{7}{2(2)}=-\frac{7}{4}=-1.75$

The y-coordinate of the vertex is given by

$\begin{gathered} f(x)=2x^2+7x-10 \\ f(-1.75)=2(-1.75)^2+7(-1.75)-10 \\ f(-1.75)=2(3.0625)^{}-12.25-10 \\ f(-1.75)=6.125^{}-12.25-10 \\ f\mleft(-1.75\mright)=-16.13 \end{gathered}$

This means that we have a minimum point.

Therefore, the minimum point of the given quadratic equation is

$(-1.75,-16.13)$

A survey about the student government program at a school finds the following results:

Serhud [2]

A total of 440 students took part in the survey. Each student makes up 0.8181818182% of the central angle of the circle graph. You get to this number by dividing 360 degrees by 440 students. Then you simply multiply this number by 110 students (who liked the program).

0.8181818182%*110=90 degrees

Write the equation of a line in point-slope form that has a slope of -1 and passes through the point (-2, 5).

vivado [14]

$The\ point-slope\ form:y-y_1=m(x-x_1)\\----------------------\\m=-1;\ (-2;\ 5)\to x_1=-2;\ and\ y_1=5\\\\\boxed{y-5=-1(x-(-2))\to y-5=-(x+2)}$

Which of these is the algebraic expression for "eight less than some number?"

kipiarov [429]

B-8 would be the answer. This is because we are saying you have 8 less than something. So no matter what something is, we are taking away 8 from it. Since our something is unknown, we use our variable 'b' in its place, and subtract 8, giving us b-8.<span />
