Answer:

A. y= -2x + 5

Step-by-step explanation:

If you plug in slope of -2 and y-intercept of (0,5) into the slope intercept form of y=mx+b then it's a.   (0,5) is on the y axis at 5. The slope means down 2 right 1.

What are the answers plz help me
Serga [27]

For number 3 it would be |-10| and |10|.

Number 5a is supposed to <, because -1 is greater than -7 when you look at the line graph. The same goes for 5b. 5d is >, because 0 is always greater than -1 and it shows that on the line graph that you have there. 5e is =.

I don't see anything else wrong though. Just the ones I listed.

Hope that helps!

The image of a point after a –90° rotation about the origin is (–4, 7). What are the coordinates of the preimage?.
ahrayia [7]
The coordinated of the preimage would be :

x  = x cos θ + y sin θ

y = x sin θ + y cos θ

where 

x = -4  
y = 7
θ = -90

What is the significance of the point of intersection of a pair of simultaneous equations
Alex777 [14]

Answer:

The point of intersection gives the solution set(s) of the associated system.

Step-by-step explanation:

If we have a pair of simultaneous equations in 2 variables in x and y, then the point of intersection is the ordered pair (x,y).

This could be a unique intersection, only one point or infinitely many intersection.

This gives us the solution of the simultaneous equations.

Therefore the significance of the point of intersection of a pair of simultaneous equations is that, it gives us the solution set(s) of the associated system.

Solve 4(x-5)= 14 please answer nowww
Anna35 [415]

Answer:

x=8.5

Step-by-step explanation:

To solve this equation, we want to find out what x is. To do this, we need to get x by itself.

Perform the opposite of what is being done to the equation. Remember to perform everything to both sides.

4(x-5)=14

4 is being multiplied by x-5. The opposite of multiplication is division. Divide both sides by 4.

4(x-5)/4=14/4

x-5=14/4

x-5=3.5

5 is being subtracted from x. The opposite of subtraction is addition. Add 5 to both sides.

x-5+5=3.5+5

x=3.5+5

x=8.5

Let's check our solution. Plug 8.5 in for x in the original equation.

4(x-5)=14

4(8.5-5)=14

4(3.5)=14

14=14

Both sides of the equation are the same, so we know our solution, <u>x=8.5 </u>is correct.
