Betty currently has $2000
Answer:
Interest rate increases by 100%+n%
n% = 1.5%
100%+1.5%=101.5%=1+0.015=1.015^x
so its y = 2000(1.015)^x

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

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
Can Anyone please explain what linear equations are
Answer:
In mathematics, a linear equation is an equation that may be put in the form {\displaystyle a_{1}x_{1}+\cdots +a_{n}x_{n}+b=0, } where x_{1}, \ldots, x_{n} are the variables, and {\displaystyle b, a_{1}, \ldots, a_{n}} are the coefficients, which are often real numbers.

Answer:
B) y = 3x - 5
Step-by-step explanation:
6x - 2y = 10
convert to y = mx + b, slope intercept form
6x - 2y = 10
-6x -6x
-2y = -6x + 10
divide by -2
y = 3x - 5

Answer:
85
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...
90-5=x
85=x
Solve the system using elimination
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

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
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:
$11.24
Step-by-step explanation:
Given data
Original cost of tire= $74.95
DIscount= 15%

= 11.24
Hence the amount saved is $11.24
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 :))
