What’s the equation to (–5, –2), (–5, 7) ?
Answer:
x=-5
Step-by-step explanation:
Since the y value goes from -2 to -7 while the x value stays constant, no matter what y value you plug in x will be -5. Therefore, the equation of this line is x=-5. Hope this helps!
what is the measure of B
Answer:
m<B = 44
Step-by-step explanation:
Since AB is a diameter, then angle C is a right angle.
That makes angles A and B complementary angles.
m<A + m<B = 90
46 + m<B = 90
m<B = 44
Answer:
B = 44
Step-by-step explanation:
The sum of the angles of a triangle is 180
A + B+ C = 180
<C = 90 since it is 1/2 of the intercepted arc which is 180
46+ B + 90 = 180
136 + B = 180
B = 180-136
B =44

£580 is divided between Sushil, Fiona & Pip so that Sushil gets twice as much as Fiona, and Fiona gets three times as much as Pip. How much does Fiona get?
Answer:
Fiona gets £ 174
Step-by-step explanation:
Ths problem has three unknowns: the amounts each person gets. So let's identify each amount with a letter to write them in mathematical equation form:
Amount Sushil gets is : "x"
Amount Fiona gets is : "y"
Amount Pip gets is : "z"
Now we write three equations based on the information we have:
1) the addition of all these amounts should equal the 580 total:
x + y + z = 580
2) Sushil (x) gets twice as much as Fiona (y):
x = 2 y
3) Fiona (y) gets three times as much as Pip (z):
y = 3 z
So we can write the first equation in terms of "z" only, by using the appropriate substitutions in the intermediate stes:
Replace every instance of "y" with "3 z":
Equation 2 can give then "x" in terms of "z" as well:
x = 2 y = 2 (3 z) = 6 z
Then Eq 1 becomes:
6 z + 3 z + z = 580
10 z = 580
and therefore:
z = £ 58
Now Fiona's amount (y) is "3 times z", therefore:
y = 3 * 58 = £ 174
The first equation from the previous system of
equations is graphed. Graph the second equation to
find the solution of the system of equations.
y = -2x + 4,
y=-x-1
What is the solution to the system?
Answer: x = 5 and y=-6
Step-by-step explanation:
If we graph both equations, the interception is the point (5,-6). Therefore the solution for x is 5 and for y is -6.

3. If angles R and S are complementary, which statement about the two angles is true?
mZR = 45° and mzs = 45°.
ZR and ZS form a right angle.
O ZR and 2S are both acute.
LR and ZS are adjacent.
Answer: ZR and ZS form a right angle
Step-by-step explanation:
Complementary angles are angles whose sum = 90ᴼ
If R and S are complementary, then their angle measures add to equal 90ᴼ
A right angle = 90ᴼ
ZR and ZS form a right angle.
What is complementary angle?When the sum of two angles is equal to 90 degrees, they are called complementary angles.
What is right angle?When two straight lines intersect each other at 90˚ or are perpendicular to each other at the intersection, they form the right angle.
According to the given question.
Angles R and S are complementary angles.
Since, R and S are complementary angles. then their angle measured add to equal to 90 degrees or right angle.
Therefore,
The ZR and ZS form a right angle.
Hence, option second is correct.

Answer: $J/3 + $5
Step-by-step explanation:
Here is the complete question:
Angela shared a cab with her friends. When they arrived at their destination, they evenly divided the $j fare among the 3 of them. Angela also paid a $5 tip. How much did Angela pay in total?
Write your answer as an expression.
Answer:
From the question, we are told that Angela shared a cab with her friends and when they arrived at their destination, they shared equally the $j fare among the 3 of them while Angela also paid a $5 tip.
The total number of friends are =3
The amount of fare = $ J
The fare is equally divided among the friends, therefore each friend will pay: $J/3
Angela paid $5 additional as a tip, therefore, her share will be: J/3 + 5
Therefore, Angela will pay $J/3 + $5
If a number is increased by 12 and then divided by 4, the result is 5. The algebraic equation is ?. The number is x= ?
Answer:
I don't have an answer but I have a helpful example.
If a number is increased by 8, the result is 25 Find the number.
Step-by-step explanation:
Let x be the number. Increasing x by 8 gives x + 8, which we are told is 25. Therefore, x + 8 = 25. Subtract 8 from both sides to find x = 17. So, the number is 17.

What is a graph?A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data. It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
For this case the first thing you should know is that we have an equation of the form:
y = mx + b
Where,
m: The slope of the line
b: Cutting point with the vertical axis.
For this case, we observe that the values of y decrease when the values of x increase. Therefore, the function decreases.
This means that it is true that:
m < 0
Therefore, the slope of the line is negative.

Sierra is driving to visit her family. She wants to drive at least 500 miles today. She has already driven 248 miles and will keep driving at a constant speed of 62 miles per hour. What number of hours can Sierra drive to meet her goal of at least 500 miles? 500 ≤ 248 + 62x Both need different answers please
Answer:
4.06451 hours
note this answer is not rounded as you did not indicate round to what decimal values.
Step-by-step explanation:
Solving using equation
500 ≤ 248 + 62x
500-248 ≤ 62x
252 ≤ 62x
252/62 ≤ x
4.06451 ≤ x
Another way to solve
500-248= 252
she needs to travel 252 miles
speed = 62mph
note: speed = distance/time
therefore time= distance/speed
time = 252/62 = 4.06451
Number of hours Sierra needs to travel to meet her goal is 4.065 hours.
What is Linear Inequalities?Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.
Sierra wants to drive at least 500 miles today.
She has already driven 248 miles.
Remaining distance is driving at a constant speed of 62 miles per hour.
Let the time needed for the remaining distance to complete is x.
Speed = Distance / Time
Distance = Speed × Time
Distance = 62x
Total distance covered = 248 + 62x
This must be at least 500.
248 + 62x ≥ 500
62x ≥ 500 - 248
62x ≥ 252
x ≥ 252 / 62
x ≥ 4.065
Hence Sierra has to drive at least 4.065 hours to meet her goal.

In Chemistry, Seth recorded the weight of copper tubing as 15.4 grams. The actual weight was 15.8 grams. What is his percent of error, rounded to the nearest percent?
Answer: -2.6%
Step-by-step explanation:
Percent error is the difference between the measured and known value, and then we divide by the known value, and then multiply by 100%.
Estimated.number = 15.4 grams.
Actual number = 15.8 grams
Percentage error = (Estimated number - Actual number)/Actual number × 100
= (15.4 - 15.8)/15.8 × 100
= -0.4/15.8 × 100
= 0.0253 × 100
= 2.53
= -2.6% approximately

[tex] = {10}^{4} \times \frac{ {4}^{10} }{ {4}^{5} } [/tex]
Next, you have to apply Indices law :
[tex] {a}^{m} \div {a}^{n} = {a}^{m - n} [/tex]
So for this question :
[tex] {10}^{4} \times \frac{ {4}^{10} }{ {4}^{5} } [/tex]
