−3x−8y=−8
y=2−x
​
yes or no

Answers

Answer 1

Answer:

No

Step-by-step explanation:

-3x-8y=-8

3x+8y=8 (multiply all terms by -1)

8y=8-3x (take 3x from both sides)

y=1-(3/8)x (divide each term by 8)

1-(3/8)x ≠ 2-x

25 would be the answer. Here's what you need to do!! :)
-
-
-
Explanation:

I think you meant [tex]2^{4}[/tex] and [tex]3^{2}[/tex]. With exponents, you don't add the number and the exponent. What you have to do is the first number times itself, and let's use number one as an example. So, since it's four you have to do this.
-
-
[tex]2^4[/tex]= 2 x 2 x 2 x 2= 16

and for problem number two, it's the same thing but different numbers.

[tex]3^{2}[/tex]= 3 x 3 x 3= 9
-
-
now, all you have to do is add [tex]16+9= 25[/tex]

Again, the answer is 25. Hope this helps anybody who's currently working on this!! <3

Answers

Answer:

Step-by-step explanation:

Graph given in the attachment represents a linear function f(x).

y = -f(x) represents the reflection of the graph across x-axis.

Therefore, y-coordinates of the points on the graph will get opposite notation after the reflection across x-axis.

Points on the graph of function f(x) are,

(0, -2), (2, 0), (4, 2) and (5, 1)

Therefore, points for the graph y = -f(x) will be,

(0, 2), (2, 0), (4, -2) and (5, -1)

Now we can plot these points to get the graph of y = -f(x)

A quadrilateral had two angles thst measure 260degrees amd 50 degrees. The other two angles are in a ratio of 2:3. What are the measures of those two angles.

Answers

Step-by-step explanation:

Here's another solution.

360-275-20=65

ratio 3:10

3x+10x=65

13x=65

x=5

5*3=15° and 5*10=50°

15° and 50° are the other two angles

Why is it reasonable to use the same units to describe circles and measure of angles?

Answers

Answer:

The more familiar unit of measurement is that of degrees. A circle is divided into 360 equal degrees, so that a right angle is 90°.

Explanation:

The unit circle, or trig circle as it's also known, is useful to know because it lets us easily calculate the cosine, sine, and tangent of any angle between 0° and 360° (or 0 and 2π radians)

As blood is pumped from the left ventricle of your heart, it flows through the aorta, a single large vessel with a diameter of about 2.5 cm. The speed of blood flow in the aorta is about 60 cm/s. Any change in pressure as blood flows in the aorta is due to the change in height: the vessel is large enough that viscous drag is not a major factor into successively smaller and smaller blood vessels until it reaches the capillaries. Blood flows in the capillaries at the much lower speed of approximately 0.7 mm/s. The diameter of capillaries and other small blood vessels is so small that viscous drag is a major factor..Because the flow speed in your capillaries is much less than in the aorta, the total cross-section area of the capillaries considered together must be much larger than that of the aorta. Given the flow speeds noted, the total area of the capillaries considered together is equivalent to the cross-section area of a single vessel of approximately what diameter?a. 25 cm b. 50 cm c. 75 cm d. 100 cm 1.
