Answer:

Answer: A. (10,-8)

Step-by-step explanation:

Y=10

X=-8

Step1. Replace the equation with the given numbers

Step2. 10=-1/4•-8+8

Step3. -1/4=-0.25

Step4. -0.25•8=2

Step5. 2+8=10

And that is how you get A.(10,-8)✌

The solution to the equation y=-1/4x+8 is (4, 8).

Thus, option (B) is correct.

Given Equation:  y=-1/4x+8

A. (10, -8)

Substitute x = 10 and y = -8 into the equation:

-8 = (-1/4)(10) + 8

-8 = -2.5 + 8

-8 ≠ 5.5

B. (4, 8)

Substitute x = 4 and y = 8 into the equation:

8 = (-1/4)(4) + 8

8 = -1 + 8

8 = 8

C. (-4, 9)

Substitute x = -4 and y = 9 into the equation:

9 = (-1/4)(-4) + 8

9 = 1 + 8

9 = 9

D. (-8, -10)

Substitute x = -8 and y = -10 into the equation:

-10 = (-1/4)(-8) + 8

-10 = 2 + 8

-10 ≠ 10

Now, (4, 8) is the only point that satisfies the equation y = -1/4x + 8.

Therefore, (4, 8) is the solution to the equation.

Thus, option (B) is correct.

Answer:

6.5 cm

Step-by-step explanation:

From Pythagoras theorem

C^2= a^2 + b^2

Where a, b are the sides of the triangle

C= hypotenus sides of the triangle

two sides are given as 1.6 cm and 6.3cm respectively.

C^2= 1.6^2 + 6.3^2

C^2= 2.56 + 39.69

C^2 = 42.25

C= √42.25

C=6.5 cm

Hence, the length of the hypotenuse is 6.5 cm

Answer:

B

Step-by-step explanation:

you can use foil and the graph,

because you can see (in the graph) that the lines intersect at 1 and 4.

just use foil to help figure out which matches the slope.

something else (the normal way) is find which 2 numbers equal to the last coefficient, in this case it can be

-2 and -2,  2 and 2, 4 and 1 or -4 and -1, multiply them and if they make up the last coefficient, and added it equals the second coefficient it is correct.

Answer:

172

Step-by-step explanation:

200 x 0.86 = 172

172 cupcakes sold were of mocha flavoured.

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Given that, a bakery sold a total of 200 cupcakes in a day, and 86% of them were mocha flavoured.

Let the number of mocha cupcakes sold are x,

Therefore, 86% of 200 = x

x = 200*86/100

x = 2*86

x = 172

Hence, the number of mocha cupcakes sold were 172.

Answer:

60 minutes

Step-by-step explanation:

To solve for the above question, we use the Lowest Common Multiple Method

We are told in the question that:

Tours for the National Capitol leave every 15 minutes. Tours for the White House leave every 20 minutes.

Find and list multiples of each number of minutes until the first common multiple is found. This is the lowest common multiple.

Multiples of 15:

15, 30, 45, 60, 75, 90

Multiples of 20:

20, 40, 60, 80, 100

Therefore,

LCM(15, 20) = 60

Therefore, the tours leave at the same time every 60 minutos

Answer:

(i) The axis of symmetry is [tex]x = -4[/tex].

(ii) The axis of symmetry is [tex]x = 4[/tex].

(iii) The axis of symmetry is [tex]x = 1[/tex].

Step-by-step explanation:

We proceed to explain how we determine the expression for the axis of symmetry for each case:

(i) [tex]f(x) = 3\cdot (x+4)^{2}+1[/tex]

The expression depicts a vertical parabola, meaning that axis of symmetry is vertical, that is, a function of the form [tex]x = a,\,\forall\,a\in \mathbb{R}[/tex]. This line passes through the vertex of the parabola. The component [tex]x+4[/tex] contains the information of the horizontal component of the vertex, where the axis passes through. Therefore, the axis of symmetry is [tex]x = -4[/tex].

(ii) [tex]f(x) = 2\cdot x^{2} -16\cdot x +15[/tex]

At first we complete the square and factor the perfect square trinomial:

[tex]f(x) = 2\cdot \left(x^{2}-8\cdot x +\frac{15}{2} \right)[/tex]

[tex]f(x) = 2\cdot \left[(x^{2}-8\cdot x +16) +\frac{15}{2}-16 \right][/tex]

[tex]f(x) = 2\cdot (x-4)^{2}-17[/tex]

By applying the approach used in (i), we find that the axis of symmetry is [tex]x = 4[/tex].

(iii) First, we locate the vertex of the parabola, which is (1,-3). The first component of the ordered pair contains all the needed information to determine the equation of the axis of symmetry, which is [tex]x = 1[/tex].

The surface area of a rectangular prism will be 164 square centimeters.

Let the prism with a length of L, a width of W, and a height of H. Then the surface area of the prism is given as

SA = 2(LW + WH + HL)

The dimension of the rectangular prism with a length of 3 cm, a width of 10 cm, and a height of 4 cm. Then the surface area of the rectangular prism is calculated as,

SA = 2(3 x 10 + 10 x 4 + 4 x 3)

Simplify the equation, then we have

SA = 2(30 + 40 + 12)

SA = 2 x 82

SA = 164 square cm

The surface area of a rectangular prism will be 164 square centimeters.

Answer:

  sin(M) = √7/4

  cos(M) = 3/4

  tan(M) = √7/3

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you of the relationships of interest.

  Sin = Opposite/Hypotenuse

  sin(M) = (2√7)/8 = √7/4

  Cos = Adjacent/Hypotenuse

  cos(M) = 6/8 = 3/4

  Tan = Opposite/Adjacent

  tan(M) = (2√7)/6 = √7/3
