Answer: y=−4/5x−4
Step-by-step explanation:
5y+4x=−20
Step 1: Add -4x to both sides. 4x+5y+−4x=−20+−4x 5y=−4x−20
Step 2: Divide both sides by 5.
y=−4/5x−4

X-2y=10 x+3y=5 please hellppppppp
Answer:
x=8,y=-1
Step-by-step explanation:
x-2y=10
x=10+2y
10+2y+3y=5
5y=-5
y=-1
x-2(-1)=10
x=8
The solution to the system of equations x - 2y = 10 and x + 3y = 5 is x = 8 and y =-1
How to solve the equation?The system of equations is given as:
x - 2y = 10
x + 3y = 5
Subtract both equations
-2y - 3y = 10 - 5
Evaluate
-5y = 5
Divide both sides by -5
y = -1
Substitute y = -1 in x - 2y = 10
x - 2(-1) = 10
This gives
x + 2 = 10
Subtract 2 from both sides
x = 8
Hence, the solution to the equations is x = 8 and y =-1

A recipe for cookie dough calls for three and two third cups of flour. Jane only ha 1 and three fourth cups of flour. How many more cups of flour does Jane to make the cookie dough?
Answer: Jane needs 1 11/ 12 cups of flour more to make the cookie dough
Step-by-step explanation:
Recipe for cookie dough= 3 2/3cups of flour
Amount of flour available for Jane = 1 3/4 cups of flour
Amount of flour Jane needs to add to make cookie dough
=3 2/3 - 1 3/4
changing to improper fraction to make it easier to subtract
11/3 -7/4 = (44- 21)/12 = 23/12 = 1 11/12 cups of flour

Answer:
75 degrees
Step-by-step explanation:
At 3:30, the hour hand is halfway between the 3 and the 4. The minute hand is exactly on the 6.
There are 360/12 = 30 degrees between each of the marked hours. The angle between the hands covers 2.5 of these gaps, so the angle between the hands is 2.5(30) = 75 degrees.
Hope this helps!
The angle between the hands at 3:30 pm is 90°.
What is the angle between the hands of a clock at 3:30 pm?
At that time, one hand points at the 3, and the other hand points at the 6.
Now, there is a rule to transform time into angles.
We know that a clock has 12 hours in a full revolution, and a circle has 360° in a complete revolution.
Then we know that:
12 hours = 360°
Then:
1 hour = (360°/12) = 30°
So each between each number in the clock we have an angle of 30°.
Then, between 3 and 6 (3 hours) we have:
3*30° = 90°
The angle between the hands at 3:30 pm is 90°.

This function is an even-degree polynomial, so the ends go off in the same directions, just like every quadratic I've ever graphed. Since the leading coefficient of this even-degree polynomial is positive, the ends came in and left out the top of the picture, just like every positive quadratic you've ever graphed.
