Answer:
d. 10.53 units
Step-by-step explanation:
This question could be answered by Pythagoras Theorem which is :
In every triangle c is always the hypotenuse ( which is the longest line in the triangle/ the line where the right angle sign is pointing to )
a or b could be either one of the other lines of the triangle it doesn't matter.
First you find AC which is simply by adding the two 5.2 values which is 10.4 units.
BC can be written as b in our Pythagoras equation and if you first substitute it you will have:
To find b you rearrange everything to the other side except b
And if you type that in the calculator you get
BC= 10.53 units (2 decimal place)
Hope it is right, and ask any questions if unsure :)))
Answer:
At 15 hours of work they will be equal.
Step-by-step explanation:
James: y = 10x + 20
Kelly: y = 8X + 50
Set them equal to each other and solve
10x + 20 = 8x + 50 Subtract 8x from both sides of the equation
2x + 20 = 50 Subtract 20 from both sides of the equation
2x = 30 Divide both sides by 2
x =15
It would be asa they have 2 congruent sides, 2 angles, and they both share QS and by the reflexive prop QS=QS so it would be asa
Answer:
(-4,-5)
Step-by-step explanation:
The slope of the line passing through (3,5) and (-2,1) would be:
It would be:
y2 - y1 / 2 and x2 - x1 / 2
= 1 -5 / 2 and -2 -3 /2
= -4/2 and -5/2
= (-4,-5)
Hope this helped :3
Answer:
The solution is x = -2, y = 4.
Step-by-step explanation:
2x + 4y = 12
x + y = 2
From the second equation: y = 2 - x.
Now substitute for y in the first equation:
2x + 4(2 - x) = 12
2x + 8 - 4x = 12
-2x = 4
x = -2.
Now find y by substituting x = -2 in the second equation:
- 2 + y = 2
y = 4.
