The equation is y-y1=m(x-x1)
Answer: Yes
Step-by-step explanation:
The formula for point-slope form is y-1₁=m(x-x₁). The given equation is y+1=8(x+6). That means the given point is (-6,-1), and the slope is 8.
Is 2 squared + 3 squared = 4 squared a true statement? Explain.
Answer:
It is not true it is false.
Step-by-step explanation:
since 2^2+3^2=4^2
4+9=16
13≠16
Step-by-step explanation:
No.
2² + 3² = 4 + 9 = 13.
4² = 16.
13 ≠ 16.
Kirsten is trying to find height using the volume of a cylinder formula, V=πr2⋅h . Which of the following would be a good first step in re-arranging the formula to isolate the height? A) divide both sides of the equation by h B) multiply both sides of the equation by r C) divide both sides of the equation by π D) multiply both sides of the equation by h
Answer:
C
Step-by-step explanation:
we want to "isolate" h (height). that means "h" needs to be alone on one side of the equation, and all other factors need to be brought to the other side.
so, yes, we need to divide both sides by all factors of h : pi and r². only then will we have the isolated h on one side.
therefore, dividing both sides by pi is a good first step.
Solve the inequality. 5+5(-7x+ 1) ≥ -130 write answer in the format variable inequality number
Answer:
x<_ 4
Step-by-step explanation:
first you distribute 5 to equal 5-35x+5 then you would carry the non variables to one side to be -35x>_-140 and the you would flip the sides because te variable is negative so it would be -35x<_ -140 the divid to get x<_4
Find the size of angle XYZ. Give your answer to 1 decimal point. Z 13cm X 4cm Y
Using the tangent ratio, the size of angle XYZ, to 1 decimal point is: 72.9°
What is the Tangent Ratio?The tangent ratio is given as, tan ∅ = opposite side/adjacent side of a right triangle.
Thus:
∅ = ∠XYZOpposite side = 13 cmAdjacent side = 4 cmThus:
tan (m∠XYZ) = 13/4
m∠XYZ = tan^-1(13/4)
m∠XYZ = 72.9°

What is the slope of the equation y= 5/4 times -7/4
Answer:
5/4
Step-by-step explanation:
If the equation is
[tex] y = \dfrac{5}{4}x - \dfrac{7}{4} [/tex]
then the slope is the number multiplying x, so
slope = 5/4.
Answer:
5/4.
The x is a variable, not a multiplication sign.
The equation is
y=mx+b
the slope is the m.
Plz i need help urgently I’ll mark brainiest the sum of a number, two thirds of the number and a quarter number of the number gives 5 3/4, find the number
Step-by-step explanation:
so you have to make an equation where you let x=the number, so it would be
x+(2/3)x+(1/4)x=5 3/4
you combine the like terms to get
(23/12)x = 5 3/4
multiply both sides by the reciprocal of 23/12 to isolate x, and you're left with
x=36/92, which simplifies to 9/23.
How do you use the GCF to write equivalent fractions?
Answer:
Step-by-step explanation:
To find equivalent fractions, we multiply the numerator and the denominator by the same number, so we need to multiply the denominator of 7 by a number that will give us 21. Since 3 multiplied by 7 gives us 21, we can find an equivalent fraction by multiplying both the numerator and denominator by 3.Oct 4, 2021

How do u do this pls someone help me I’ve failed math for 3 quarters straight
Answer:
1. 84in³
2. 180cm³
3. 600ft³
4. 360cm³
5. 312cm³
6. 15.6kg
7. 1.95kg
Step-by-step explanation:
1: V = Bh = (7x3)x4 = 84in³
2: V = Bh = 1/2(8x5) x 9
= 20 x 9
= 180cm³
3: V = Bh = 1/2(b1+b2) h x 5
= 1/2(20+10) 8 x 5
= 15 x 8 x 5
= 15 x 40
= 600ft³
4: V = Bh = 1/2 (4x9) x 20
= 18 x 20
= 360cm³
5: Total volume = Volume of rectangular prism + Volume of triangular block
= (8.5 x 4 x 9) + 1/2(1.5 x 2) x 4
= 306 + 6
= 312cm³
6: divide 312cm³ by 20kg/cm³ to get the approx. mass:
312/20 = 15.6kg
7: first find the volume of the friends Display:
= (4.25 x 2 x 4.5) + 1/2(0.75 x 1) x 2
= 38.25 + 0.75
= 39cm³
Now divide by 20 to find the approx. weight of the friends display:
39/20 = 1.95kg

Problem 8
Answer: angle LSO and angle MSN
--------------
Explanation:
Vertical angles form when we intersect two line segments, lines, or rays. Vertical angles are opposite one another and they are always congruent.
=============================================
Problem 9
Answer: angle LMS and angle SMN
--------------
Explanation:
Adjacent angles share a common line, line segment, or ray. Think of two adjacent rooms sharing a common wall between them. In the case of the answer above, the two angles share the common segment SM (note how S and M are part of LMS and SMN)
When it comes to naming angles, the middle letter is always the vertex of the angle. This is the hinge so to speak. Or you could picture a pair of scissors. For angle LMS, the arms LM and SM are the two blades of the scissors while point M is where the blades meet.
=============================================
Problem 10
Answer: angle LSM and angle MSN
--------------
Explanation:
Same idea as problem 9. Now we're making S the middle letter. Something like angle LSM is the same as angle MSL.
In this case, the two adjacent angles form a straight line. We consider these two angles a linear pair.
=============================================
Problem 11
Answer: angle LSO and angle OSN
--------------
Explanation:
The term linear pair was discussed back in problem 10. So you could list those two angles again, or you could go with another pair as shown above. All that matters is that they are adjacent angles and they are supplementary angles (they add to 180 degrees). There are many possible answers.
Something like the angle pair angle LOS and angle NOS are adjacent angles, but they aren't supplementary. So we don't meet the condition of a linear pair here.

explain the steps in finding the midpoint of the points (-1,2) and (3,-6). The state the midpoint
Answer:
(1, -2)
Step-by-step explanation:
midpoint x = (x₁ + x₂) / 2
midpoint y = (y₁ + y₂) / 2
[tex](\frac{-1 + 3}{2} , \frac{2 + -(6)}{2} )[/tex]
= (1, -2)
The midpoint of the points (-1,2) and (3,-6) is (1, -2).
What is Midpoint?
To find the midpoint of numbers, add two numbers and divide by 2.
Given that;
Two points are (-1,2) and (3,-6).
Now,
Let midpoint of the points (-1,2) and (3,-6) is (x, y)
The value of x = (-1 + 3)/2
= 2/2
= 1
And, The value of y = (2 + (-6))/2
= -4/2
= -2.
Thus, The midpoint of the points (-1,2) and (3,-6) is (1, -2).

Water is flowing into an inverted cone, of diameter and height 30 cm at a rate of 4 litres per minute. How long, in seconds,
will it take to fill the cone?
1st question : volume to be filled in liter ?
V cone = 1/3 x base area x h
= 1/3 x pi x r² x h
= 1/3 x 3,14 x (30:2)² x 30
= 1/3 x 3,14 x 15² x 30
V cone = 7,065 cm3 ≈ 7 dm3 ≈ 7 liters
then
we know 4 liters .............1 minute
we are looking for 7 liters............. n minute
4 x n = 7 x 1
n = 7/4
n = 1,75 min => = 1 min + 0,75x60 = 1 min and 45 sec
Tiana has 2 2/3 gallons of paint. She uses 1/2 of the total amount to paint her room. She gives of the remaining paint to her brother. How many gallons of paint does Tiana give to her brother?
Answer:
2 1/6
Step-by-step explanation:
How we calculate this is make the two fractions denominators the same so we can make them both 6.
for the 3 we times it by 2 and 2 by 3.
so our 2 fractions are now 2 4/6 and 3/6 Now
so if we take away 3 of 4 we get 1 so 2 and 4/6 is now 2 and 1/6
Meaning the 2 1/6 is what she has left so if she gives that all to her brother he gets that and there's your answer.
Hope it helps have a great afternoon:)
