Step-by-step explanation:

So there ya go

D=R

and now bout the range ya gotta find the vertex, which is:

[tex] x = \frac{ - b}{2a} \: \: y = \frac{Δ}{4a} [/tex]

now pay attention

X=2/–2=–1

y=–(–1)²–2(–1)+3=4

Now the highest point of your parabolic chart is 4 and the lowest point is endless which is (–♾,4]

Well, finally your answer is D

the answer is D. hope i helped

Find the roots/zeroes of the following polynomial

x^2−19=6

Answers

Answer:

x=5 and x=-5

Step-by-step explanation:

1. first you would subtract 6 from both sides to set the equation = to zero.

2. The equation would then be x^2-25=0.

3. that is a difference of two squares polynomial. So when you factor it, it is (x+5)(x-5)=0

4. by the zero product property, the roots are 5 and -5.

if (x/3+1,y-2/3)is equal to (5/3,1/2) find the value of x and y

Answers

Answer:

The value of x is 2.

The value of y is [tex]\frac{7}{6}[/tex]

Step-by-step explanation:

We have that:

[tex]\frac{x}{3} + 1 = \frac{5}{3}[/tex]

Multiplying everything by 3

[tex]x + 3 = 5[/tex]

[tex]x = 2[/tex]

The value of x is 2.

We have that:

[tex]y - \frac{2}{3} = \frac{1}{2}[/tex]

Least common multiple between 3 and 2 is 6, which means that we multiply everything by 6.

[tex]6y - 4 = 3[/tex]

[tex]6y = 7[/tex]

[tex]y = \frac{7}{6}[/tex]

The value of y is [tex]\frac{7}{6}[/tex]

Answers

9514 1404 393

Answer:

610 m²

Step-by-step explanation:

If we extend the horizontal line across the right-hand portion of the figure, then the figure is divided into two rectangles:

bottom: 5 m × 50 m = 250 m²

top: 18 m × 20 m = 360 m²

The sum of these areas is the shaded area:

shaded area = 250 m² +360 m² = 610 m²

3x + y = 4

8x + 2y = 10

Answers

Answer:

I take it that we solve for x and y, so we have

3x + y = 4, so we have y = 4 - 3x

and plug that in to

8x + 2y = 10

8x - 6x + 8 = 10

2x = 2

x = 1

y = 4 - 3

y = 1
