How do you find the slope? I know y=mx=b but I still dont understand
Answer:
There are two ways you can find the slope(atleast thats what I know)
Step-by-step explanation:
Hello, i have two ways.
We can find the slope in y = mx+b form or the slope in y=mx+b itself
We can also find the slope with the graph drawn.

Answer:
x = 5
y = 1/4
Step-by-step explanation:
Let a = 1/x
b = 1/y
Then the equations are
(1) 10a - 4b = -14 and (2) 5a + 8b = 33 Multiply equation (2) by -2
-10a - 16b = -66
-20b = - 80
b = 4 5a + 8(4) = 33
5a + 32 = 33
5a = 1
a = 1/5
a = 1/x = 1/(1/5) x = 5
b = 1/y = 4 y = 1/4

Step-by-step explanation:
complementary angles = 90* so 85+5=90
Answer:
85
Step-by-step explanation:
Complementary means those angles add up to 90
supplementary means those angles add up to 180
because on angle is 5 degrease and it says complementary you just...

An expression is shown.
1 3/7 divided by 1 1/3
What is the value of the expression as a mixed number?
Answer:
1 ¹⁄₁₄
Step-by-step explanation:
[Step 1] [convert mixed fractions to improper fractions]
1 3/7 divided by 1 1/3 →
a b/c = b + a(c) / c = (b + ac) / c.
3 + 1(7) / 7 divided by 1 + 1(3) / 3 →
10 / 7 divided by 4 / 3.
[Step 2] [flip the numerator and denominator(take the reciprocal) of the fraction you are dividing by and multiply]
10 / 7 divided by 4 / 3 →
a / b → b / a = 1 / (a / b) = (a / b) ^ -1.
10 / 7 multiplied by (3 / 4).
When you multiply 2 fractions, you multiply across. Numerator × Numerator / Denominator × Denominator.
a / b × c / d = (a × c) / (b × d).
10 / 7 multiplied by (3 / 4) →
10 / 7 × 3 / 4 →
(10 × 3) / (7 × 4) →
30 / 28.
[Reduce completely until the denominator or numerator is prime or can only be divided by one and itself to remain an integer]
30 / 28 →
15 / 14.
[Find the difference between the numerator and denominator and that will be the numerator of the mixed fraction or the remainder, the denominator will be the same denominator of the improper fraction and the whole part will be how many times the denominator can fit in the numerator of the improper fraction]
[Or you can do long division and you will add the quotient (top number above long division bar) and the remainder.]
a / b = (# times b fits into a) + (remainder / b).
15 / 14 = (# times 14 fits into 15) + (1 / 14).
15 / 14 = 1 + (1 / 14)
15 / 14 = 1 ¹⁄₁₄
What is the length of one side of a cube that has a surface area of 2400 square mm?
a. 20.00 mm
b. 24.29 mm
c. 17.32 mm
d. 8.16 mm
Answer:
A)20.00mm
Step-by-step explanation:
since the cube has 6 faces divide it by 6.
= 2400 ÷ 6
=400
1 face = 400 area
since the surface of the cube is square and its area is 'side square'
find the square root of 400
which is 20 cm (side)
Also, I took the test and got it correct.
Answer:
a) 20.00mm
Step-by-step explanation:
Since the cube has 6 faces divide it by 6.

Solve for h.
h/6 − 1 = −3
h =
Answer:
[tex]h = - 12[/tex]
Step-by-step explanation:
1) Add 1 to both sides.
[tex] \frac{h}{6} = - 3 + 1[/tex]
2) Simplify -3 + 1 to -2.
[tex] \frac{h}{6} = - 2[/tex]
3) Multiply both sides by 6.
[tex]h = - 2 \times 6[/tex]
4) Simplify 2 × 6 to 12.
[tex]h = - 12[/tex]
Therefor, the answer is h = -12.
Answer:
h = - 12
Step-by-step explanation:
Add 1 to both sides of the equation
ℎ/6 − 1 + 1 = − 3 + 1
Simplify
ℎ/6 = − 3 + 1
h/6 = -2
Multiply all terms by the same value to eliminate fraction denominators
6 ⋅ ℎ/6 = 6 ( − 2 )
Cancel multiplied terms that are in the denominator
ℎ = 6 ( − 2 )
Multiply the numbers
ℎ = − 12

Evaluate the expression 6x + 21y when Y = 4 x=3
Answer:
102
Step-by-step explanation:
You have to substitute x and y. Since x = 3 and y = 4, you would write the equation as 6(3) + 21(4). Multiply that, and you get 18 + 84. Add that together, and you get the answer 102.
Answer: 102
Step-by-step explanation: 6x + 2y
6(3) + 21(4)
18 + 84
102
basically you just plug in 4 where it says y in the equation and plug in 3 where it says x in the equation and solve :))

Write and solve two division expressions that have a negative quotient. Use the fractions − 2 /3 , 5/ 6 , and − 1 4 . Show your work.
Answer:
By remembering a few simple rules, you will be able to divide any negative fraction problem you come across. Ignore the negative sign at first and multiply one fraction by the reciprocal of the other. The reciprocal is attained by simply flipping the numerator and the denominator.

Answer:
(4, -10), (4, 6)
Step-by-step explanation:
The vertical diameter is on the vertical line through the center of the circle. That line is x=4.
The square of the radius is 64, so the radius is √64 = 8. The y-coordinate of the diameter end points will be the y-coordinate of the center ±8.
So, the points of interest are ...
(4, -2±8) = (4, -10) and (4, 6) . . . . end points of the vertical diameter
Beth bought two new tires for here race car. Each tire originally cost 74.95$. She recieved a 15% discount. How much money did she save on the purchase of the tires?
Answer:
