Step-by-step explanation:

Answer:

y-intercept = (0, 8)

x-intercepts = (4, 0) and (-2, 0)

vertex = (1, 9)

5th point = (2, 8)

Step-by-step explanation:

As the coefficient of x² is negative, the curve will be "n" shaped.

y-intercept

crosses the y-axis when x = 0

substitute x = 0 into the function and solve for y:

[tex]\implies y=-(0)^2+(2 \times 0)+8=8[/tex]

Therefore, y-intercept = (0, 8)

x-intercept

crosses the x-axis when y = 0

set the function to zero and solve for x:

[tex]\implies -x^2+2x+8=0[/tex]

[tex]\implies x^2-2x-8=0[/tex]

[tex]\implies (x-4)(x+2)=0[/tex]

[tex]\implies x=4, x=-2[/tex]

Therefore, x-intercepts = (4, 0) and (-2, 0)

vertex

vertex form:  [tex]y=a(x-h)^2 +k[/tex],  where (h, k) is the vertex

expand vertex equation:  [tex]y=ax^2 -2ahx+ah^2 +k[/tex]

compare coefficients with original function: [tex]y=-x^2+2x+8[/tex]

[tex]\implies a=-1, h=1, k=9[/tex]

So vertex = (1, 9)

5th plot point

You can choose any value of x and input it into the equation for y, but for symmetry, I have chosen to find the other value of x (aside x = 0) when y = 8

[tex]\implies -x^2+2x+8=8[/tex]

[tex]\implies -x^2+2x=0[/tex]

[tex]\implies x^2-2x=0[/tex]

[tex]\implies x(x-2)=0[/tex]

[tex]\implies x=0, x=2[/tex]

5th point = (2, 8)

The value of the given expression is -15 - 3y

In maths, when there are terms in the bracket, it means we are to multiply the terms in the brackets by each other. This means that 5 + y would be multiplied by -3.

Multiplication is the process of determining the product of a set of numbers.

(5 + y)(–3) = -15 - 3y

Step-by-step explanation:

Sq root of 7 = 2.65

Answer:

2nd number line represents √7 best

Step-by-step explanation:

Method 1

√7 ≈ 2.65

Therefore, the 2nd number line represents √7 best

(the one with the dot between 2 and 3)

Method 2

√1 = 1

√4 = 2

√9 = 3

Therefore, as √7 is between √4 and √9, the solution is somewhere between 2 and 3.

Answer:

70

Step-by-step explanation:

First, set up the ratio of c:t, which is 12:8. Then set up your new ratio of c:t, which is 105:?. The way I find the easiest is to divide 105 by 12, which is 8.75, then multiply that by 8, which is 70. To check if it's right, just divide 12 by 8, and 105 by 70, and if they're the same number, you've got it right.

Answer:

x = 130°

y = 50°

Step-by-step explanation:

x = 130° (Exterior alternate angles)

x + y = 180° (Angles in linear pair)

y = 180° - x

y = 180°- 130°

y = 50°

The solution to the problem in the figure attached in the question is: x = 130°, y = 50°

Alternate angles are angles that are formed in a situation whereby a line intersects two other lines, which lie on opposite sides of a transverse line and on contrasting proximate sides of the other lines.

From the given figure:

Angle x is an alternate angle to angle 130°.

Thus, x = 130°

Using the sum of angles on a straight line:

x + y = 180°

130° + y = 180°

y = 180° - 130°

y = 50°

Answer:

if m∠1 = 30° then m∠3 = 30° as they are parallel to each other and that is why they will have same angles.

therefore m∠3 = 30°

extra's:

→ m∠2 = m∠4 =

→ (360-30*20)/2

→ 150°

m<1 and m<3 are opposite angles to eachother.

And we know that opposite angles are equal

Step-by-step explanation:

so, we first put 10 in for x :

y = 6.50×10 + 50 = 65 + 50 = $115

and then we put 20 in for x :

y = 6.50×20 + 50 = 130 + 50 = $180

so, the ordered pairs are

(10, 115) and (20, 180)

Answer:

81 cm²

Step-by-step explanation:

Start by finding the perimeter of a rectangle.

[tex]Perimeter = 2(l+w)[/tex]

Plug in the given values into the equation:

[tex]Perimeter=2(14+4)=2(18)=36\ cm[/tex]

Since the perimeter of a square is:

[tex]Perimeter = 4s[/tex]

We can plug 36 cm in for the perimeter to solve for s

[tex]36\ cm=4s[/tex]

Divide both sides by 4

[tex]s=9\ cm[/tex]

The area of a square is:

[tex]Area=s^2[/tex]

Plug in the 9 cm for s

[tex]Area=9^2=81 \ cm^2[/tex]

Step-by-step explanation:

• the original price= 275,

275 → 100 %

i) find the price with the 15 % discount

100% - 15% = 85 %

if, 275 → 100 %

100 % → 275

1% → 275 / 100

85 % → (275/100) * 85

= 233. 75

ii) find the add. 5% of the :

sale price = 233. 75

add. discount = 5%

= 5/ 100 * 233.75

= 11.6875

iii) subract the 5% discount from the sale price.

final price = 233. 75 - 11.6875

= 222. 0625
