Find the slope of 3x+4y=-4

Answer:

B=-1

Step-by-step explanation:

Standard form is Ax+By=C.

In this case, Ax is x, By is 1/5y, and C is +2.

To isolate the 2 (the C), subtract x from both sides of the equation:

x+2=1/5y

-x     -x

2=-x+1/5y.

Now, the value of B, the x value, is -1.

Answer:

700

Step-by-step explanation:

100%-66%=34%

34% equals the 238 that is red

238÷34%=7 people per percentage

7×66%= 462 students that chose purple

462+238=700 which should be the total amount of people surveyed.

Answer:

7/9 = 14/18

4/10 = 16/40

8/10 = 4/5

12/16  = 6/8

18/21 = 6/7

Step-by-step explanation:

Answer:

7/9 is equivalent to 14/18

4/10 is equivalent to 16/40

3/12 is equivalent to 2/8

8/10 is equivalent to 4/5

12/16 is equivalent to 6/8

18/21 is equivalent to 6/8

Answer:

(3,3)

Step-by-step explanation:

Since it's to the left, and not up or down at all, the y-value does not change. The x-value, however, is affected. Since it's to the left, it is decreasing in value by 2 points. If it were to the right, it would increase in value to (7,3), since it'd be going further away from (0,0).

Answer:

Q  = (3,3)

Step-by-step explanation:

Moving the point left moves the x value down 2.

5-2=3

Therefore, Q = (3,3)

Answer:

Yes

Step-by-step explanation:

One triangle can be bigger then another and still have the same angle measure.

Yes, it is possible for two triangles to have the same angle measures but not be congruent.

If two triangles are congruent, this means they are the same shape and the same size.

One triangle can be bigger than another and still have the same angle measure. For example, if there are two equilateral triangles all the angles are 60 degrees.

But one triangle is having a side of 10 units and the other triangle is having a side of 20 units means the second triangle is bigger than the first but the angle for both the triangles is 60 degrees.

Therefore, it is possible for two triangles to have the same angle measures but not be congruent.

96.023 is the answer yeah

Given:

[tex]4=-2\left(x-3\right)[/tex]

To find:

The error that a student has made while solving the equation.

Solution:

We have,

[tex]4=-2\left(x-3\right)[/tex]

Using distributive property, we get

[tex]4=-2(x)-2(-3)[/tex]

[tex]4=-2x+6[/tex]

Subtract 6 from both sides.

[tex]4-6=-2x+6-6[/tex]

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

Divide both sides by -2.

[tex]1=x[/tex]

The value of x is 1.

In step 2, the distributive property is not used properly because when -2 is distributive with -3 then we get 6 instead of -6.

Therefore, the student has made error in step 2.

Answer:

A.

Step-by-step explanation:

It's literally the same equation written in reverse, which according to the commutative property, can be done.

Answer: A

Step-by-step explanation:

For this problem, we know that A is the correct answer. A is the same as the given expression because it is the same, but the order is switched. When you multiply both of them, you would get the same answer.

We can eliminate B because [tex]\frac{2}{5}[/tex] should be positive, not negative.

We can eliminate C because the fraction should be [tex]\frac{2}{5}[/tex], not [tex]\frac{5}{2}[/tex].

We can eliminate D because (-1×-7) given you 7, not -7.

Therefore, A is the right answer.

Answer:

(3x + 4y)(x + 2y)

Step-by-step explanation:

3x^2+ 10xy + 8y^2

All signs are positive, so we'll only look at positive factors of 3 and 8.

3 factors into 3 and 1.

8 factors into 4 and 2, and it also factors into 8 and 1.

I like to try closer factors in value, so I'll start with 4 and 2 for 8.

Try:

(3x + 2y)(x + 4y) = 3x^2 + 12xy + 2xy + 8y^2 = 3x^2 + 14xy + 8y^2

The middle term does not work. Switch 2y and 4y and try again.

Try:

(3x + 4y)(x + 2y) = 3x^2 + 6xy + 4xy + 8y^2 = 3x^2 + 10xy + 8y^2

It works.

Answer: (3x + 4y)(x + 2y)

Answer:

The answer is C:All real solutions

Step-by-step explanation:

here are the steps in case u need them :)

Step 1: Simplify both sides of the equation.

−2(x+3)=−2x−6

(−2)(x)+(−2)(3)=−2x+−6(Distribute)

−2x+−6=−2x+−6

−2x−6=−2x−6

Step 2: Add 2x to both sides.

−2x−6+2x=−2x−6+2x

−6=−6

Step 3: Add 6 to both sides.

−6+6=−6+6

0=0

Answer:

C: All real numbers.

Step-by-step explanation:

-2 ( x + 3 ) = -2x -6

-2 times x, -2 times 3

-2x -6 = -2x -6

Add 6

-2x -6 +6 = -2x -6 +6

-2x = -2x

same as....

0 = 0
