What is the x-intercept for the following linear equation:

1 answer:

3 0

The "x-intercept" occurs when y=0, because it is at this point that the equation touches the x axis. So if you plug in y=0 into the equation you can solve for the x coordinate.

4x-2(0)-8=0

4x-8=0

4x=8

x=2

So the x-intercept is the point (2,0)

The length of rectangle is 3 cm longer than its breadth. If the perimeter of the rectangle is 54 cm, find its length,in cm

Ilia_Sergeevich [38]

Answer:

Length=15cm

Hope this answer is right!!

Step-by-step explanation:

Length be 3 cm longer than the breadth.

So, x=y+3

Perimeter = 2(x+y)54

So, x+y=27 =>x=15

x-y=3 =>x=12

So, length is 15 cm

Simplify

guajiro [1.7K]

Answer:

$h^{24}$

Step-by-step explanation:

$(\frac{h^{12}}{h^4})^3\\ (h^8)^3\\h^{24}$

When dividing two exponents (of the same bases) you subtract the exponents. When there is an exponent to an exponent, you multiply the to exponents.

Given these facts, determine how many cans of paint you would need to buy to paint 2 walls.

Tatiana [17]

Answer:

3 cans

Step-by-step explanation:

A = lw

a = 20 x 8 = 160 $ft^{2}$

a = 40 x 8 = 320 $ft^{2}$

Together this is 480 $ft^{2}$

I would need 3 cans.

Are these triangles similar? if so, what postulate or theorem justifies that they are similar?

Karo-lina-s [1.5K]

Answer:

Yes The triangles are similar by SAS Similarity Theorem

Step-by-step explanation:

we know that

Side-Angle-Side Similarity, states that If an angle of a triangle is congruent to an angle of another triangle and if the included sides of these angles are proportional, then the two triangles are similar

In this problem

Angle L is congruent with Angle Z

Verify if the included sides are proportional

$\frac{LJ}{ZY}=\frac{KL}{XZ}$

substitute the values

$\frac{3}{1.5}=\frac{4}{2}$

$2=2$ -----> is true

therefore

The triangles are similar by SAS

Place the decimal point in the answer to make it correct. Explain your reasoning. 3.9853X8.032856 = 32013341.

horsena [70]

1. The Given problem is to find where to place the decimal point to the product shown below.
3.9853 x 8.032856, notice that the given equation are decimal numbers with both ones place value of the whole number.
Now, given the answer 32013341 without decimal point, let’s find where to put the decimal point.
=> 3.9853 x 8.032856
=> 32.013341
Thus, the decimal point is now located after the 2nd number. We now have 2 whole numbers with value of tens.
