For y=-5x , what is the y intercept

2 answers:

The y intercept is zero (0) because the slope is -5 and no other number is listed so there’s an implied +0 so the y intercept is zero

Hello!

The equation above has been written in slope-intercept form, which uses the following formua:

y = mx + b

In the formula above, “m” represents the slope of the line while “b” represents the y-intercept. With this knowledge, we can see that the given equation has a slope of (-5). You’ll notice, however, that the given equation does not have a “b” value. In this case, the fact that “b” is not included in the equation implies that this particular value is equal to zero.

Consequently, we have now come to the conclusion that the y-intercept (b) is equal to zero.

I hope this helps!

Find the length of x. Assume the triangles are similar.

Katyanochek1 [597]

Triangles are similar and only differ in size meaning they are dilated

So first we have to find the scale factor of dilation (by how much the smaller triangle got bigger)

Find scale factor:

2.4a=4.8

z=2

Find x:

we multiply the original side of the small side with the scale factor of 2

2.8(2)=x

5.6=x

So, x=5.6

Find the value of x.<br> 16.2<br> 0.03<br> 38.5<br> 34.8

ella [17]

Hi there!

$\large\boxed{x = 38.5}}$

To solve, we can use right triangle trig.

We are given the value of ∠A, and side "x" is its adjacent side. We are also given its opposite side, so:

tan (A) = O / A

tan (33) = 25 / x

Solve:

x · tan(33) = 25

x = 38.49 ≈ 38.5

Jerry’s rhombus has a base of 15 inches and a height of 9 inches. Charlene’s rhombus has a base and a height that are 13 the bas

neonofarm [45]

Answer: The area of Charlene's rhombus is nine times smaller than the area of Jerry's rhombus.

Step-by-step explanation:

I will assume that the exercise says " $\frac{1}{3}$ times the base and height of Jerry’s rhombus".

The area of a rhombus can be calculated with the following formula:

$A=b*a$

Where "b" is the length of the base and "a" is the altitude or the height.

Then, you can calculate the area using the formula shown above.

Therefore, you get:

1. Jerry's rhombus:

$A_1=(15\ in)(9\ in)\\\\A_1=135\ in^2$

2. Charlene's rhombus:

$A_2=(\frac{1}{3}*15\ in)(\frac{1}{3}*9\ in)\\\\A_2=(5\ in)(3\ in)\\\\A_2=15\ in^2$

Dividing the area calculated, you get:

$\frac{135\ in^2}{15\ in^2}=9$

Therefore, you can conclude that the area of Charlene's rhombus is nine times smaller than the area of Jerry's rhombus.

Answer: the statement “measure of <4 is 105 degrees” is incorrect.

Explanation: This is because since both angles 1 and 3 are vertical, this means they are both 95. This gives us 190 (95x2). Now we subtract this from 360 which gives us 170. Since angles 2 and 4 are vertical, we divide by 2, which gives us 85, not 105.

Hope this helps! :)
