HELP ASAP!!!!!!!!! Please answer both

Answer:

(- 1, - 3 )

Step-by-step explanation:

Given the 2 equations

2x + y = - 5 → (1)

2x - 5y = 13 → (2)

Subtracting (1) from (2) term by term will eliminate the x-0 term

0 - 5y - y = 13 - (- 5) , that is

- 6y = 18 ( divide both sides by - 6 )

y = - 3

Substitute y = - 3 into either of the 2 equations and solve for x

Substituting into (1)

2x - 3 = - 5 ( add 3 to both sides )

2x = - 2 ( divide both sides by 2 )

x = - 1

solution is (- 1, - 3 )

Answer:

You must know the shape of the graph y = x². Its chart is in the form of an upward parabola. The shape of the graph y = -x² is the same except that it is downward. Finally, to draw the shape of the graph y = -x² + 9, we need to move the previously mentioned graph 9 units upwards.

The formula for the vertex length of a parabolic chart is as follows: x= -b/(2a) b=0 , a= 1 → x= 0, y=-(0)²+9=9

vertex: (0,9)

The Triangle EHL and MPE by HL Congruence Rule.

Two triangles are said to be congruent if their sides and angles are the same length. Two triangles can thus be stacked side by side and angle by angle.

Two triangles are said to be congruent if their sides are the same length, their angles are the same measurement, and they may be superimposed on each other.

As, from the figure in Triangle EHL and MPE

EH = MP

EL = ME

<EHL = < MPE = 90

As, If the hypotenuse and a leg of one right triangle are congruent with the hypotenuse and leg of another right triangle, the triangles are congruent.

So, the Triangle EHL and MPE is Congruent by HL Congruence Rule.

Answer:

The new volume is 375 cubic inches.

Step-by-step explanation:

Volume of a right square prism:

The volume of a right square prism is given by:

[tex]V = a^2h[/tex]

In which a is the length of the edge and h is the height.

A right square prism has a volume of 75 cubic inches.

This means that:

[tex]a^2h = 75[/tex]

The prism is enlarged so its height is increased by a factor of 5

Edge is the same, height is 5 times. So

[tex]a^2(5h) = 5(a^2h) = 5*75 = 375[/tex]

The new volume is 375 cubic inches.

Answer: it will cost $3.768 to fill the cone to its full capacity.

Step-by-step explanation:

The frozen yoghurt is filled in cone shaped cups. The formula for determining the volume of a cone is expressed as

Volume = 1/3πr²h

Where

h represents the height if the cone.

r represents the radius of base of the cone.

π is a constant whose value is 3.14

From the information given,

r = 3 inches

h = 5 inches

Volume = 1/3 × 3.14 × 3² × 5 = 47.1inches³

If customers pay $0.08 per cubic inch, it means that the amount that it would cost to fill the cone to its full capacity is

0.08 × 47.1 = $3.768

Answer:

Step-by-step explanation:

4x + 3y = 6 -----------------(I)

4x - y =2 ---------------------(II)

Multiply (II) by (-1) and  then add

(I)                4x + 3y = 6

II) *(-1)        - 4x + y  = - 2   {Now add, x will be eliminated}

                         4y = 4

                           y= 4/4

y= 1

Plugin y =1 in equation (I)

4x +3*1 = 6

4x + 3 = 6

      4x = 6- 3

      4x = 3

        x = 3/4

Answer:

( [tex]\frac{3}{4}[/tex], 1 )

Step-by-step explanation:

Given the 2 equations

4x + 3y = 6 → (1)

4x - y = 2 → (2)

Subtract (2) from (1) term by term to eliminate x

4x - 4x + 3y - (- y) = 6 - 2, that is

4y = 4 ( divide both sides by 4 )

y = 1

Substitute y = 1 into either of the 2 equations and solve for x

Substituting into (1)

4x + 3(1) = 6

4x + 3 = 6 ( subtract 3 from both sides )

4x = 3 ( divide both sides by 4 )

x = [tex]\frac{3}{4}[/tex]

solution is ( [tex]\frac{3}{4}[/tex], 1 )

Answer:

h = 16 cm

Step-by-step explanation:

Given that,

The area of a trapezium, A = 512 cm²

The sum of the length of the parallel sides = 64 cm

The area of a trapezium is given by :

[tex]A=\dfrac{1}{2}\times \text{sum of parallel sides}\times height\\\\h=\dfrac{2A}{Sum}\\\\=\dfrac{2\times 512}{64}\\\\=16\ cm[/tex]

So, the distance between the parallel sides is 16 cm.

Answer:

l = 6.00

Step-by-step explanation:

So A = l x w and P = 2l + 2w, they say they are equal to l (w) = 2l + 2w and we know that w = 3 so

3l = 2l + 2(3), so l = 6.

Step-by-step explanation:

Use the exterior two secant intersecting theorem,

The Outside Angles Theorem states that the measure of an angle formed by two secants, two tangents, or a secant and a tangent from a point outside the circle is half the difference of the measures of the intercepted arcs.

In other words,
