Write equations of the horizontal and vertical lines that pass through (−5,−4).
Horizontal-

Answers

Answer:
Horizontal line:
y=-4
Vertical line:
x=-5

Explanation:
Equation of a horizontal line:
y=b
B is the y-intercept (the point on the line that crosses the y axis)

Equation of a vertical line:
x=d
D is the x-intercept (the point on the line that crosses the x axis)

To find the values of b and d, we just need to look at the coordinate and see what’s in place of the x and y variables.

(x,y)
(-5,-4)

-5 is the x coordinate and -4 is the y coordinate. Therefore,

y=-4
x=-5

Answer:

c. m∠2 = m∠5

Step-by-step explanation:

We can check 1 by 1 and find the false one.

For answer A, measures 2 and 4 are vertical angles, which means they are equal, so that's not false.

For answer b, measures 4 and 8 are corresponding angles, since X and Y are parallel, so that's also not false.

For answer c, measures 2 and 5 are supplementary to each other, and since the transversal is not perpendicular to X nor Y, they are not equal, therefore, this is false, making that the answer.

For answer d, measure 2 and 6 are corresponding angles, so that's also not false.

Therefore, the answer must be c.

See, when you have a fractional exponent, you can turn it into a square root. The 1/3 power is the same as the cubed root. As you can see in my example, I took the cubed root of 8 which is a perfect 2. I brought that to the outside.

Now this is the kind of tricky part. You have to break the exponents into 3rds. Turn the x^4 into x^3*x^1. The x^3 has a perfect cubed root of just x, now bring that out but keep the other x underneath the radical. Repeat this for the other exponents where it actually applies.

In the end, I brung all the perfect roots out and kept the rest underneath the radical. It turns out the two radicals are the same and they cancel. The 2’s also cancel. You’re stuck with:

Answer:6(-4)

Step-by-step explanation:

Answer:

4(-6), 6(-4), 12(-2)

Step-by-step explanation:

Hi there!

A negative number times a positive number is a negative number. So, since -4 x 6 has one negative number, you can think of it as 4 x 6 and then add a minus sign after multiplying, so -4 x 6 is -24.

In multiplication, no matter which way the equation goes, the answer will always be the same ( 5 x 3 is the same as 3 x 5). Therefore, we are looking for another equation that will also equal -24.

4(-6) is the same because it is still one number that is a negative, and it still equals -24.

6(-4) is the same as well, it's just we're putting the parentheses around the -4 this time.

12 x 2 is 24, so 12(-2) is negative 24 (-24)

Answers

Answer:

Step-by-step explanation:

Given the functions

F(x) = 6-x²

G(x) = x²+4x-12

A) we are to find F(x)+g(x)

F(x)+G(x) = 6-x²+x²+4x-12

F(x)+G(x) = 6+0+4x-12

F(x)+G(x) = 4x+6-12

F(x)+G(x) = 4x-6

The domain of the function is the values of x for which the expression exists. The expression exists on all real interval i.e xER

F(x)-g(x) = 6-x²-(x²+4x-12)

F(x)-g(x) = 6-x²-x²-4x+12

F(x)-g(x) = 6-2x²+4x+12

F(x)-g(x) = -2x²+4x+6

The domain of the function is the values of x for which the expression exists. The expression exists on all real interval i.e xER

3) F(x)/G(x)

= 6-x²/x²+4x-12

The domain of the function is the values of x for which the expression exists. The expression exists on all real interval i.e xER

explain how using fraction strips with like denominators makes it possible to add fractions with unlike denominators.

Answers

Because you don’t have to change the fractions so that they have equal denominators which you need in order to add fractions

Fraction strips uses (least)  common denominators, thus splitting big fraction into sum with like denominators and thus making addition possible.

Fraction strips require three major steps.

1. Firstly convert the problem with modelling as fraction strips.

2. Find the common denominator which should be least of all.

3. Now calculate the sum on new converted fractions.

For example:

[tex]\begin{aligned}\dfrac{1}{2} + \dfrac{3}{4} &= \dfrac{1}{4} + \dfrac{1}{4} + \dfrac{3}{4}\\&= \dfrac{2}{4} + \dfrac{3}{4}\\&= \dfrac{5}{4} = \: Ans.\end{aligned}[/tex]

3/5 (2m-10)=2/3m+10

Answers

Answer:

m = 30

Step-by-step explanation:

3/5 (2m-10)=2/3m+10

Distribute

6/5 m - 6 = 2/3m +10

Subtract 2/3 m from each side

6/5 m - 2/3 m - 6 = 2/3m -2/3m +10

6/5 m -2/3m - 6 =  10

Add 6 to each side

6/5 m -2/3m - 6+6 =  10+6

6/5m -2/3m = 16

Get a common denominator of 15

18/15 m - 10/15 m  =16

8/15 m = 16

Multiply each side by 15/8

15/8 *8/15 m = 16*15/8

m = 30
