Answer:

An equation with a slope of -3

Step-by-step explanation:

Parallel lines have their slopes equal

This means the line you should pick should have a slope of -3

In this case;

3x + y = 1 ----write it in slope-intercept form as;

y = -3x + 1 ------m , slope = -3

The equation to pick should have a slope of -3

Answer:

Point B

Step-by-step explanation:

In the graph of y = f(x),

For every x-value (input value), value of the function is the y-value (output value).

For the input value x = -2,

Output value of the function will be,

y = 2

f(-2) = 2

Therefore, point B will represent the input-output values of the function.

Answer:

               Not executable

Step-by-step explanation:

f(x) = a(x - h)² + k      - vertex form of the equation of the parabola with vertex (h, k)

so the equation of parabola with the vertex (24, 10) is  :

f(x) = a(x - 24)² + 10  

the parabola's axis of symmetry parallel to the y-axis and passing through point (4,290) means:  h = 4

That  means you write something wrong in your question.

Answer:

[tex]y = x^2 - 5x - 14[/tex]

Step-by-step explanation:

Given

[tex]x = -2[/tex] and [tex]x = 7[/tex]

Required

Determine the quadratic equation with a leading coefficient of 1

First, we equate both expression to 0

[tex]x = -2[/tex] and [tex]x = 7[/tex]  becomes

[tex]x + 2 = 0[/tex] and [tex]x - 7 = 0[/tex]

Multiply both expressions:

[tex](x + 2) * (x - 7) = 0 * 0[/tex]

[tex](x + 2) (x - 7) = 0 * 0[/tex]

Open Brackets

[tex]x^2 - 7x + 2x - 14 = 0[/tex]

[tex]x^2 - 5x - 14 = 0[/tex]

Hence, the quadratic equation is:

[tex]x^2 - 5x - 14 = 0[/tex]

or

[tex]y = x^2 - 5x - 14[/tex]

The formula, in standard form y = ax^2 + bx + c, for a quadratic that has roots at x = -2 and x = 7 is y = x² - 5x + 14

Given the standard form of quadratic equation expressed as [tex]ax^2 + bx+c =0[/tex]

If a quadratic that has roots at x = -2 and x = 7, then their factors will be x+ 2 and x - 7.

Taking the product of the factors will give:

f(x) = (x+2)(x-7)

f(x) = x² - 7x + 2x - 14

f(x) = x² - 5x + 14

Hence the formula, in standard form y = ax^2 + bx + c, for a quadratic that has roots at x = -2 and x = 7 is y = x² - 5x + 14

Step-by-step explanation:

The quadrilateral is a parallelogram if and only if it has two pairs of parallel sides option (D) is correct.

In two-dimensional geometry, it is a plane shape having four sides, in which two pairs of sides are parallel to each other and equal in length. The sum of all angles in a parallelogram is 360°.

It is given that:

A parallelogram is a quadrilateral with two pairs of parallel sides.

As we know,

The quadrilateral can be defined as the four-sided polygon in geometry having four edges and four corners.

The quadrilateral, has:

Two pairs of congruent sides.

It has one pair of opposite congruent angles.

The diagonals of a kite are perpendicular.

One diagonal is bisected.

The top and bottom angles are bisected but does not have congruent diagonals.

A quadrilateral is a parallelogram if and only if it has two pairs of parallel sides.

Thus, the quadrilateral is a parallelogram if and only if it has two pairs of parallel sides option (D) is correct.

Answer:

7+4=11

Step-by-step explanation:

12/3 equalls 4 because the 12÷3=4.

Answer:

(15, 11).

Step-by-step explanation:

Given the system of equation;

X=2y-7 ..... 1

4x+y=71 ....2

Substitute 1 into2;

4(2y-7) + y = 71

8y - 28 + y = 71

9y - 28 = 71

9y = 71 + 28

9y = 99

y = 11

Substitute y = 11 into 1;

x = 2y - 7

x = 2(11)-7

x = 22-7

x = 15

hence the solution to the equation is (15, 11).

Answer:

The length of the hypotenuse is 2 square root of 13 ⇒ c

Step-by-step explanation:

The rule of the area of the right triangle is A = [tex]\frac{1}{2}[/tex] × leg1 × leg2, where

leg1 and leg2 are the sides of the right angle

∵ The area of a right triangle is 12 in²

∵ The ratio of the length of its legs is 2: 3

→ Let leg1 = 2x and leg2 = 3x

∵ leg1 = 2x and leg2 = 3x

→ Substitute them in the rule of the area above

∴ 12 = [tex]\frac{1}{2}[/tex] × 2x × 3x

∵ 2x × 3x = 6x²

∴ 12 =  [tex]\frac{1}{2}[/tex] × 6x²

∴ 12 = 3x²

→ Divide both sides by 3 to find x²

∴ 4 = x²

→ Take √ for both sides

∴ x = 2

→ Substitute x in the expressions of leg1 and leg2 to find them

∴ leg1 = 2(2) = 4 inches

∴ leg2 = 3(2) = 6 inches

∵ hypotenuse = [tex]\sqrt{(leg1)^{2}+(leg2)^{2}}[/tex]

∴ hypotenuse = [tex]\sqrt{(4)^{2}+(6)^{2}}=\sqrt{16+36}=\sqrt{52}[/tex]

∵ The simplest form of [tex]\sqrt{52}[/tex] = 2[tex]\sqrt{13}[/tex]

∴ The length of the hypotenuse = 2[tex]\sqrt{13}[/tex] inches

Answer:

30 flyers

Step-by-step explanation:

A printer prints:

1 flyer = 2 1/2 seconds = 2.5 seconds

1 batch of flyers = 75 seconds

The number of flyers in a batch is:

2.5 seconds = 1 flyer

75 seconds = x

Cross Multiply

2.5 × x = 75 × 1

x = 75/2.5

x = 30 flyers.

Therefore, the number of flyers in a batch is 30 flyers
