What is the equation in slope-intercept form of the line that crosses the y-axis at 6 and is perpendicular to the line represented by y= (-4/9)x+5?
Answer:
y=(9/4)x+6
Step-by-step explanation:
If it crosses at 6 then it will be +6. A perpendicular line has a slope that is the opposite reciprocal of your current slope.
Which number is greater?

What is the 149th term in the arithmetic sequence below?
3 11 19 27
A) a(149) = 1187
B) a(149) = 1199
C) a) 149) = 1184
D) a(149) = 1189
I got 141 obviously that's completely incorrect plz help
Answer:
1,187
Step-by-step explanation:
The nth term of an arithmetic sequence is expressed as;
an = a + (n-1)d
a is the first term
n is the number of terms
d is the common difference
Given the sequence 3, 11, 19, 27...
a = 3
d = 11-3 = 19-11 = 8
n = 149 (since we need the 149th term)
a149 = 3 + (149-1)(8)
a149 = 3+(148)(8)
a149 = 3+1,184
a149 = 1,187
Hence the 149th term is 1,187

Mariah has a spinner that has 10 equal sections, each containing a different number from 1 to 10. Mariah determines about how many times the spinner will land on a number that is greater than 7 in 250 spins, and her work is shown below.
P (number greater than 7) = StartFraction Number greater than 7 over Total number of sections EndFraction times number of spins = StartFraction 4 over 10 EndFraction (250) = 100.
What mistake did Mariah make, if any?
Mariah has the formula reversed; it should be the total number of sections over the numbers greater than 7.
Mariah should have used a 3 in the numerator because there are 3 numbers greater than 7.
Mariah should multiply by the number of sections in the spinner rather than the total number of spins.
Mariah calculated the prediction correctly and did not make any mistakes.
Answer:
Mariah should have used a 3 in the numerator because there are 3 numbers greater than 7.

Jayce bought 5 bath towels and returned 2 hand towels. His sister Jayna bought 3 bath
towels and returned 4 hand towels. Jayce paid a total of $124 and Jayna paid a total of
5b - 2h = 124
$24. The system of equations
models this situation, where b is the
3b - 4h = 24
price of a bath towel and h is the price of a hand towel. How much does each kind of
towel cost?
Answer:
Bath towels = $32
Hand towels = $18
Step-by-step explanation:
Given:
5b - 2h = 124 (1)
3b - 4h = 24 (2)
Multiply (1) by 2 to eliminate h
10b - 4h = 228 (3)
3b - 4h = 24 (2)
Subtract (2) from (3)
10b - 3b = 248 - 24
7b = 224
b = 224 / 7
b = 32
Substitute b = 32 into (2)
3b - 4h = 24
3(32) - 4h = 24
96 - 4h = 24
-4h = 24 - 96
-4h = -72
h = -72 / -4
= 18
h = 18
Bath towels = $32
Hand towels = $18
Let f(x) = x^2 and g(x) = x - 5 Find (f o g)(-2)

Write the following expression in exponential form: (2 points) 4.5 × 4.5 × 4.5 × 4.5 × 4.5 × 4.5 × 4.5
Answer:
The answer is [tex]4.5^7[/tex]
Step-by-step explanation:
This is because there are 7 copies of the same number and that means you have to put 7 at the exponential part of it. Then you have to put the original number under the exponential spot. Therefore, the answer is [tex]4.5^7[/tex].

I need help on this I would appreciate if you could Help me thank you
Answer:
(x1, y1)=(-1, -2)
(x2, y2)=(3, 6)
Step-by-step explanation:
y=2x
y=x^2-3
Since both of the expressions 2x and x^2-3 are equal to y, set them equal to each other forming an equation in x
2x=x^2-3
solve the equation for x
x=-1
x=3
Substitute the given value of x into the equation y=2x
y=2 x (-1)
x=3 y=2 x 3
Solve the equation for y
y=-2
y=2 x 3 y=6
The possible solutions of the system are the ordered pairs (x, y)
(x1, y1)=(-1, -2)
(x2, y2)=(3, 6)
Check if the given ordered pairs are the solutions of the system of equations
-2=2x(-1)
-2=(-1)^2-3
6=2x3
6=3^2-3
Simplify the equalities
-2=-2
-2=-2
6=2x3
6=3^2-3
-2=-2
-2=-2
6=6
6=6
Since all of the equalites are true, the ordered pairs are the solution of the system
(x1, y1)=(-1, -2)
(x2, y2)=(3, 6)
