Chantal made a mistake in her simplification What step is it?

40

P(42) = (6/7)(42) + 4 = 36 + 4 = 40

Answer:

1

Step-by-step explanation:

since the 2 functions equal each other:

-2x + 3 = 4x - 9

add -2x to both sides

3 = 6x - 9

add 9 to both sides

12 = 6x

divide by 6

2 = x

you have x, now find y, you just need to plug 2 into one of the equations instead of both bc they both equal the same anyway

-2(2) + 3

-4 + 3

-1 = y

Now we'll find x + y, input them and it's 2 + (-1), which is 1

Step-by-step explanation:

The base of triangle will be 12 cm.

A triangle is a three-sided polygon.

The area of a rectangle is commonly known to be b*h, where b is the base and h is the height. Using the formula for a rectangle, we can get the area of a triangle.

A rectangle is split into two congruent triangles by a diagonal. The area of each triangle is equal to half the size of the rectangle.

As a result, the triangle's area A may be calculated using the equation A=1/2*b*h, where b denotes the triangle's base and h its height.

AREA OF TRIANGLE = 1/2*b*h

base = area of triangle * 2 / h

         = 30 * 2 / 5

         = 12 cm.

Step-by-step explanation:

Answer:

All the points to the right of 0 are rational

Step-by-step explanation:

rear above

The possible value of the expression is 5 > y > 3

The expression is given as

1/5 < 1/y < 1/3

Take the exponent of the sides of the inequality

(The inequality sign would change)

So, we have

5 > y > 3

Hence, the possible value of the expression is 5 > y > 3

Step-by-step explanation:

5x2x12 is 120

2x12+5 is 29

2x(12+5) 19

5x(2+12) 70

i say its 280 miles because the point is at half of 320 and 240 and 320-240 is 80 and half of eithegy is 40 therefore 240+40 is 280

Given:

Two points are (-4, 0) and (2, 0).

To find:

The slope of the line that passes through the given points.

Solution:

The line passes through the points (-4, 0) and (2, 0). So, the slope of the line is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{0-0}{2-(-4)}[/tex]

[tex]m=\dfrac{0}{2+4}[/tex]

[tex]m=\dfrac{0}{6}[/tex]

[tex]m=0[/tex]

Therefore, the slope of the line that passes through the points (-4, 0) and (2, 0) is 0.

Answer:

p = 2

r = 4

Step-by-step explanation:

If you're doing parallel it needs to be like "side by side." The least you can do is 2 because you'll need at least one other line to be beside the original.

Perpendicular lines are intersecting, so if you intersect them as a plus sign, you'll make at least four right angles.

Answer:

The remainder is: f(-1) = -4

Step-by-step explanation:

We know that when a polynomial function f(x) is divided by x-c, then the remainder is f(c)

Given the function

[tex]f\left(x\right)\:=\:x^4\:-\:5[/tex]

It is stated that the function f(x) is divided by x + 1.

Thus, substituting x = -1 in the function to find the remainder f(-1)

i.e

f(-1) = (-1)⁴ - 5

f(-1) = 1 - 5

f(-1) = -4

Therefore,

The remainder is: f(-1) = -4
