What's the intercepts for the equation 4x-6y-5z=60?

Rudik [331]

To find the $x_i$ intercept, set $x_j=x_k=0$ . By this I refer to the following procedure.

x-intercept: Set $y=z=0$ , then you're left with $4x=60\iff x=15$ . Then the x-intercept is $(15,0,0)$ .

y-intercept: Set $x=z=0$ , then $-6y=60\iff y=-10$ . The y-intercept is $(0,-10,0)$ .

z-intercept: Set $x=y=0$ , then $-5z=60\iff z=-12$ . The z-intercept is $(0,0,-12)$ .

Answer

5. ΔABC ≅ ΔDEF is true.

6. ΔABC ≅ ΔGHI is not true.

Step by step explanation

5. Find the lengths of the triangle ABC.

BC = 3

Use the distance formula to find the length of AB and AC

Distance formula = $\sqrt{(x2 - x1)^2 + (y2 - y1)^2}$

Coordinates of A = (1, 4) and B = (2, 2).

Now plug in these values in to the distance formula.

AB = $\sqrt{(2 -1)^2 + (2 - 4)^2} \\$

AB = $\sqrt{(1)^1 + (-2)^2}$

AB = √1 + 4

AB = √5

Now let's find the length of AC.

A = (1, 4), C = (5, 2)

Use the distance formula and the length of AC.

AC = $\sqrt{(5 - 1)^2 +(2 - 4)^2}$

AC = $\sqrt{(4)^2 + (-2)^2}$

AC = √(16 + 4)

AC = √20

Now let's find the length of GI

G = (6, 6) and I = (8, 1)

Use the distance formula.

GI = √(2)^2 + (-5)^2

GI = √(4 + 25)

GI = √29.

The length of EF = 3, DE = √5, EF = √20

Now let's compare the two triangles ABC and DEF.

The sides of the triangle ABC is equal to the sides of the triangle DEF

By SSS property, ΔABC ≅ ΔDEF.

6) The side length of GI = √29 which is not equal to the side length of AC = √20.

Therefore, the ΔABC ≅ ΔGHI is not true.

Hope this will help you.

Thank you.

The table represents a function.

zavuch27 [327]

Answer:

The correct option is 3. The rate of change in the function $y=x-6$ is less than the rate of change of the function represented in the table.

Step-by-step explanation:

The given table represents a function.

Choose any two points from the table. The two points are (0,-5) and (2,1).

Slope of a line is

$m=\frac{y_2-y_1}{x_2-x_1}$

Slope of the function that is represented by the table, is

$m=\frac{1-(-5)}{2-0}=\frac{6}{2}=3$

Therefore the rate of change of function is 3.

The given function is

$y=x-6$

It is a slope intercept form of a line.

$y=mx+b$

Where m is the slope and b is y-intercept.

Therefore the slope of the given function is 1.

Since 1<3, therefore rate of change in the function $y=x-6$ is less than the rate of change of the function represented in the table. Option 3 is correct.

In triangles DEF and OPQ, ∠D ≅ ∠O, ∠F ≅ ∠Q, and segment DF ≅ segment OQ. Is this information sufficient to prove triangles DEF a

kenny6666 [7]

In triangles DEF and OPQ, ∠D ≅ ∠O, ∠F ≅ ∠Q, and segment DF ≅ segment OQ; this is not sufficient to prove triangles DEF and OPQ congruent through SAS

<h3>What are congruent triangles?</h3>

Two triangles are said to be congruent if they have the same shape, all their corresponding angles as well as sides must also be congruent to each other.

Two triangles are congruent using the side - angle - side congruency if two sides and an included angle of one triangle is congruent to that of another triangle.
