(click photo) i’ve posted this 3 times and no ones helped me :((( PLEASE help me with 3-8. i’d really appreciate it. i’m the worst at math! :(
Answer:
5) Slope(m): 2
y-intercept(b): (0, 4)
6) Slope(m): -1
y-intercept (b): (0, -6)
7) Slope(m): 5
y-intercept (b): (0, 8)
8) Slope(m): 7
y-intercept (b): (0, 1/2)
Step-by-step explanation:
in order to find the slope and y-intercept you need to rewrite the equation in y=mx+b.
in 5, the equation is -2x+y=4. we need to add 2x to both sides to get y=2x+4. now you can find your slope (2) and your y-intercept point (0, 4)
in 6, the equation is x+y=6. we need to subtract x from to both sides so we get y=-x+6. you would get a slope of -1 and a y-intercept point of (0, 6)
in 7, the equation is -5x=8-y. we need to add 5x to both sides to get 0=8-y+5x. then add y to both sides so we get the equation y=5x+8. you have a slope of 5 and a y-intercept point of (0, 8)
in 8, the equation 0=1-2y+14x. we need to add 2y to both sides and we get 2y=14x+1. since we need y to stand alone we need to divide both sides by 2. now we have y=7x+1/2. the slope is 7 and the y-intercept point is (0, 1/2)
Hope this helps!! :)
find the measure of angle A
Answer:
35 degrees
Step-by-step explanation:
Sum of angles inside a triangle is 180 degrees.
Right angle is 90 degrees.
180 = 90 + (x + 46) + (x + 66) = 2x + 202
x = -11
A = x + 46 = -11 + 46 = 35

Answer:
42
Step-by-step explanation:
in order to find y, we need to find x.
180-65-62=53
x=53
we need to subtract 53-?=11
53-42=11
y=42
Answer:
42
Step-by-step explanation:
because the triangles are congruent, we can place the angle x in CDE to solve for it. Knowing the sum of all angles in a triangle is 180, we can set up the formula below.
62 + 65 + x = 180
Additionally, because the triangles are congruent, we know that the length of CD is equal to GH, letting us set up this formula:
x - y = 11
Solving the first formula, we now know the value of x, 53.
62 + 65 + 52 = 180
Plugging that into the second formula and solving, we get 42.
53 - 42 = 11

Answer:
√35i
Step-by-step explanation:
i is an imaginary number. It represents the square root of negative one. By pulling it out, we pull out the negative, and our answer uses the unit i. Because 35 cannot be simplified, we are done.
Answer:
We know that √-1 = i, where "i" is the imaginary unit
± √(-35) = ± √(35) i
± √(35) i is the right answer.Someone help with this please

The ratio of number of text messages sent by Lucas to the number of text messages sent by his sister is 4 to 9. Lucas sent 72 text messages. How many text messages did his sister send?
Answer:The number of text messages sent by his sister=162
Step-by-step explanation:
Step 1
The ratio of number of text messages sent by Lucas to the number of text messages sent by his sister =4 to 9= 4:9
Number of text messages sent by Lucas =72
Total ratio is given as 4+ 9= 13
Step 2
such that the total number of messages sent by Lucas and by his sister will be calculated as
Ratio of text messages sent by Lucas/ total ratio x Total messages = Number of text messages sent by Lucas . Let X = Total number of messages
4/13 x X = 72
X=72 x 13 / 4 =234
Therefore, The number of text messages sent by his sister= ratio of text messages sent by his sister/ Total ratio x Total number of messages =
9/13 X 234= 162 messages

The volume of this sphere is 972 pi cubic inches. What is its radius?
A sphere.
Recall the formula Sphere Volume = four-thirds pi r cubed
Answer:
Step-by-step explanation:
volume of sphere = 4πr³/3 = 972π in³
r³ = 729 in³
r = 9 in
The value of its radius is,
⇒ r = 6.14 inches
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
The volume of this sphere is 972 pi cubic inches.
Now, We know that;
Volume of sphere is,
⇒ V = 4/3πr³
⇒ 972 = 4/3 × 3.14 × r³
⇒ 972 × 3 = 12.56 × r³
⇒ r³ = 232.16
⇒ r = ∛232.16
⇒ r = 6.14 inches
Thus, The value of its radius is,
⇒ r = 6.14 inches

A line with a slope of -4 passes through the point (0, 0). What is its equation in
slope-intercept form?
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer: y = -4x
Step-by-step explanation: You would use the formula y = mx + b to solve your problem. When you plug the numbers in, you get y = -4x. There would be no "+ b" because in this case, the y-intercept (b) is equal to zero. Therefore, you would not need to write "y = -4x + 0" because that would not be the equation in its simplest form.
