Can anyone help me I was self isolating when my class was taught this and I can't get in contact with my teacher
Answer:
Step-by-step explanation:
3x +2y = 13 -----------------(i)
x + 2y = 7 ----------------(ii)
Multiply the equation (ii) by (-1) and then add.
(i) 3x + 2y = 13
(ii)*(-1) -x - 2y = -7 {Now, add and y will be eliminated}
2x = 6
x = 6/2
x = 3
Plug in x = 3 in equation (i)
3*3 + 2y = 13
9 + 2y = 13
2y= 13 - 9
2y = 4
y = 4/2
y = 2
Answer:
1. x=3 y=2 ---- 2. x=5 y=1 ---- 3. x=2 y=4 ---- 4. x=3 y=2 ---- 5. x=5 y=1 ---- 6. x=5 y=5
Step-by-step explanation:
1. 3x3=9, 2x2=4, 9+4=13
2. 2x5=10, 5x1=5, 10+5=15
3. 4x2=8, 2x4=8, 8+8=16
4. 3+(2x2)=7
5. 3x5=15, 10x1=10, 15-10=5
6. 3x5=15, 3x5=15, 15+15=30

The distance (in miles) traveled when driving at a certain speed s for 15 hours, then driving 13 miles/hour
faster for another hour. Express tthe distance in terms of s
We have to know the relation between speed, time and distance to solve the question. The distance travelled expressed in terms of s is 16s+13.
The speed of a vehicle or person can be given by the distance travelled over time taken to travel the distance. We can find the time,distance and speed from this relation if we know any two of the three variables. Here in this question we have to assume the speed to be s,we know the different time intervals and we have to find out the distance travelled in terms of s. Distance can be calculated by multiplying speed by time taken. In the question it says that the first it travels at a speed s for 15 hours,so we can say for first half distance travelled is 15s, for the second part it says that it travels at a speed (s+13) miles/hour for 1 hour so we can say that the distance travelled for second part is (s+13) miles. Thus total distance travelled can be given by adding up first and second part
distance travelled=15s+(s+13)=16s+13 miles
Therefore we get the total distance travelled in terms of s to be 16s+13 miles.

Answer: x = 3 or -13/3
Step-by-step explanation: if you sub in 3 for x, you'll get 9+2 =11, which is true. -13/3 is also correct since subbing it in will give you -13+2, which equals -11. The absolute value of -11 is 11. So both of them work
Determine how many feet each member of Lola's family walked. Lola's pet turtle walked $$10 feet, and then half that length again. Lola's baby brother walked $$3 feet, and then half that length again. Lola's hamster walked $$6.5 feet, and then half that length again. Lola's mom walked $$x feet, and then half that length again.
Answer: See explanation
Step-by-step explanation:
Lola's pet turtle walked 10 feet, and then half that length again. This means that Lola's pet turtle walked:
= 10 + (1/2 × 10) = 10 + 5 = 15 feet
Lola's baby brother walked 3 feet, and then half that length again. Total length walked will be:
= 3 + (1/2 × 3) = 3 + 1.5 = 4.5 feet
Lola's hamster walked 6.5 feet, and then half that length again. Total length walked will be:
= 6.5 + (1/2 × 6.5) = 6.5 + 3.25 = 9.75
Lola's mom walked x feet, and then half that length again. Total length walked will be:
= x + (1/2 × x) = x + 0.5x = 1.5x
Total feet walked by the whole member of the family will be:
= 15 + 4.5 + 9.75 + 1.5x
= 29.25 + 1.5x
Answer:
turtle:15
baby brother:4.5
hamster:9.75
mom: 1.5x

Evaluate the expression below if x = 3 and y= -4.
X - Y - 3+ (-57)
Answer:
-53
Step-by-step explanation:
If x=3 and y=-4
Plug the numbers into the equation
3 - (-4) - 3 + (-57)
Now solve the equation right to left
3 - (-4) = 7
7 - 3 = 4
4 - 57 = -53
So the answer is -53

Ja are perpendicular, because they
have slopes that are
Help!!!
Answer:
line a and b are parallel, there is no perpendicular lines
Step-by-step explanation:
Looking at the slope of each line, you can identify whether the lines are parallel, perpendicularlar, or neither.
When the slopes are the same, they are parallel.
When the slopes have opposite sign and numerator and denominator flipped, they are perpendicular. Ex. [tex]\frac{a}{b}[/tex] and [tex]-\frac{b}{a}[/tex] are perpendicular slopes.
Finding slope is using the formula: [tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]
Line a has slope [tex]\frac{3-4}{4-0}[/tex] = [tex]-\frac{1}{4}[/tex]
Line b also has slope [tex]-\frac{1}{4}[/tex]
Line c has slope 2
Since slope of line a and b are same, they are parallel.
Line c is not perpendicular to line a and b because the slope should have opposite sign and numerator and denominator flipped, which is 4 not 2.

If x = 3 (y + 2) minus 1 what is the value of w in terms of x and y?
w = StartFraction x minus 3 y Over 3 EndFraction
w = StartFraction x minus 3 y + 1 Over 3 EndFraction
w = x minus 3 y + 1
w = StartFraction x + 1 Over 9 y EndFraction
Answer:
[tex]w=\dfrac{x-3y+1}{3}[/tex]
Step-by-step explanation:
The given expression is :
x = 3 (y + w) -1
We need to find the value of w in terms of x and y.
Solving RHS of the given expression :
x = 3y+3w-1
subtracting both sides 3y.
x-3y = 3y+3w-1 -3y
x-3y = 3w-1
Add 1 both sides
x-3y+1=3w-1+1
3w=x-3y+1
[tex]w=\dfrac{x-3y+1}{3}[/tex]
Hence, the correct option is (c) "[tex]w=\dfrac{x-3y+1}{3}[/tex] i.e. w = StartFraction x minus 3 y + 1 Over 3 EndFraction.

Answer:
7% increase
Have a nice day :)
Answer: Decay; -7% increase
You could also say "7% decrease" but it looks like your teacher wants "increase" in there, so you have to make the value negative.
=============================================================
Explanation:
The base of the exponential is 0.93
Compare this to 1+r and we see that 1+r = 0.93 solves to r = -0.07
The negative r value indicates exponential decay. Specifically we have 7% decay. The amount is decreasing by 7% each time x increases by 1 unit.
The phrasing "7% decrease" is the same as "-7% increase", though in my opinion, "7% decrease" sounds more natural and easier to conceptualize.

Step-by-step explanation:
When 3 positive numbers are multiplied together, the product will be positive. In fact, when any number of positive numbers are multiplied together, the product will always be positive.
Examples: 5*7*14=490
1*2*3*4*5*6*7=5040
When 3 negative numbers are multiplied together, the product will be negative. Two negatives make a positive and a negative and a positive will make a negative. Because the product of the first two numbers will be positive, the final product will be negative.
Examples:
(-9)(-2)(-5)
Two negatives make a positive
= 18(-5)
A negative and a positive make a negative
= -90

Asap anwer plssssss!!! Ed can ride 30km on the bicycle in the same time it takes him to walk 14km. If his riding rate is 10kph faster than his walking rate, what is his walking rate
Answer: 8.75
Step-by-step explanation:
Let walking rate = x
Riding rate = x + 10
Time taken to ride 30km = time taken to walk 14 km
Time = distance / speed
Hence,
30/ (x + 10) = 14 / x
Cross multiply :
30x = 14( x + 10)
30x = 14x + 140
30x - 14x = 140
16x = 140
x = 140 / 16
x = 8.75
Walking rate = 8.75 kph
