Answer:
y = 5x + 1
Step-by-step explanation:
Lines that are parallel to each other on a graph would have the same slope but different y-intercepts. When option A's equation is graphed along with the line given in the question, the lines appear to be parallel.
Option A should be the correct answer.
D= # of dimes
q= # of quarters
QUANTITY EQUATION:
d + q= 64
COST EQUATION:
0.10d + 0.25q= $9.25
STEP 1:
multiply quantity equation by -0.10 to be able to eliminate the d term in step 2
(-0.10)(d + q)= (-0.10)(64)
-0.10d - 0.10q= -6.40
STEP 2:
add equation from step 1 to cost equation to eliminate the d term and solve for q
Add
0.10d + 0.25q= $9.25
-0.10d - 0.10q= -6.40
0.15q= 2.85
divide both sides by 0.15
q= 19 quarters
STEP 3:
substitute q value in step 2 into either original equation to find d value
d + q= 64
d + 19= 64
subtract 19 from both sides
d= 45 dimes
CHECK:
0.10d + 0.25q= $9.25
0.10(45) + 0.25(19)= 9.25
4.50 + 4.75= 9.25
9.25= 9.25
ANSWER: There are 45 dimes and 19 quarters.
Hope this helps! :)
The only point which is a solution is C
Answer:
The correct answer is Kinetic Energy
Step-by-step explanation:
From conservation of energy a body at rest posses energy called Potential Energy under which it acquired at particular position of the body i.e at rest
Then as soon body starts moving with a certain speed "v" there is conservation of energy from Potential energy to Kinetic energy given as product of a half with mass of the body and square of its velocity.
In formular K.E= 1/2mv^2 where m stands for mass of the body and v is the speed of the body.
Answer:
7
Step-by-step explanation:
The segment perpendicular to the chord bisects it. The hash marks indicate that both chords are the same length, so their distance from the center is the same. x = 7
