Answer:
x = 3
y = 2
Step-by-step explanation:
5x - 3 = 6y
5x + 3 = 9y
y = 5/6 x - 1/2
5x + 3 = 15/2 x - 9/2
-5/2 x + 15/2 = 0
-5/2 (x - 3) = 0
x = 3
Answer:
x = 3
y = 2
Step-by-step explanation:
because it's a rectangle, opposite sides are equal
AD = BC
AB = DC
so we can use their measures to create a system of equations:
5x + 3 = 9y
5x - 3 = 6y
if we multiply the first equation by -1 we can eliminate the x-values:
-(5x + 3 = 9y)
-5x - 3 = -9y
+ 5x - 3 = 6y
-6 = -3y
y = 2
If y = 2 then BC = 12 and we can set up this equation:
12 = 5x - 3
15 = 5x
3 = x
The sum of 6 and y is greater than – 16.
Answer: 6+y < -16

Step-by-step explanation:
Power is the result of multiplying two numbers together. The correct option is 2×2×2×2×2×2, 4×16, and 8×8.
What is power?Power is the result of multiplying two numbers together. Power is typically expressed by a base number and an exponent. The base number indicates the number being multiplied. The exponent, which is a little number printed above and to the right of the base number, indicates the number of times the base number is multiplied.
The given expression can be written as,
2⁶ = 2 × 2 × 2 × 2 × 2 × 2
= 4 × 16
= 8 × 8
Hence, the correct option are 2×2×2×2×2×2, 4×16, and 8×8.

Answer:
1. 144 2. 16 3. 1 4. 3x-6
Step-by-step explanation:
So think of this as a function in a function. So you work from the inside to the outside. So for problem 1, we start with f(4)) [you read it "f of 4"] so what is the solution when x = 4, since f(x) means the function of x so f(4) means 'the function of 4' inside f(x).
Since f(x) = 3x then f(4) = 3(4) [notice how you substitute the 4 everywhere you see a letter x]
so f(4) = 12, now you work the next part h(f(4)) since f(4)=12 then h(12)
So take the h(x) function which is h(x) = [tex]x^{2}[/tex] then h(12) = [tex]12^{2}[/tex] so h(12) = 144

Choose the missing step in the given solution to the inequality −2x − 14 > −4 + 3x.
−2x − 14 > −4 + 3x
−5x − 14 > −4
_____________
x < −2
A. −5x < 10
B. −5x > −18
C. −5x > 18
D. −5x > 10
Answer:
Step-by-step explanation:
-2x - 14 > -4 + 3x
subtract 3x from both sides
-5x - 14 > -4
add 14 to both sides
-5x > 10
divide both sides by -5
x < -2
The answer would be -5x > 10.
This is because our last inequality was -5x - 14 > -4 so we add 14 to both sides and it would look like this -5x (-14 + 14) > (-4 + 14) which would transition into our next inequality -5x > 10.
So therefore the answer would be -5x > 10.
i need help i don understand i got b but it said it was wrong .
Answer:
b is 135 and c is 45.................thanks
Answer:
[tex]b=135\\c=45[/tex]
Step-by-step explanation:
The angle that measures 135 degrees and angle b are opposite angles. Opposite angles are congruent. Therefore, angle b=135.
[tex]b=135[/tex]
A straight line has an angle measure of 180 degrees. This means that 135+c would equal 180 degrees.
[tex]135+c=180[/tex]
Subtract both sides by 135
[tex]135+c-135=180-135\\c=45[/tex]

Given the measure of two of the angles, find the measure of the 3rd
Answer:
Measure of 3rd angle is 80 degrees
angle SAX - angle PAX = measure of 3rd angle (SAP)

A line that includes the point (6,-4) has a slope of -1/2 what’s the equation in slope intercept form
Answer:
The equation in the slope-intercept form will be:
[tex]\:y=-\frac{x}{2}-1[/tex]Step-by-step explanation:
Given
Point (6, -4)Slope m = -1/2Important Tip:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
[tex]m[/tex] represents the slope[tex]b[/tex] is the y-interceptIn our case,
(x, y) = (6, -4)m = -1/2Step 1 of 2
Determine the y-intercept b
substitute m = -1/2 and (x, y) = (6, -4) in the slope-intercept form of the line equation
[tex]y = mx+b[/tex]
[tex]-4\:=-\:\frac{1}{2}\left(6\right)+b[/tex]
switch sides
[tex]-\frac{1}{2}\left(6\right)+b=-4[/tex]
[tex]-3+b=-4[/tex]
Add 3 to both sides
[tex]-3+b+3=-4+3[/tex]
simplify
[tex]b=-1[/tex]
Thus, the y-intercept b = -1
Step 2 of 2
substitute the values
substitute b = -1 and m = 1/2 in the slope-intercept form of the line equation
[tex]y = mx+b[/tex]
[tex]y=-\frac{1}{2}x+\left(-1\right)[/tex]
[tex]\:y=-\frac{x}{2}-1[/tex]
Conclusion:
Therefore, the equation in the slope-intercept form will be:
[tex]\:y=-\frac{x}{2}-1[/tex]

$77 at 16% for 6 months
What is the difference between the total amount in the account if you did simple and compound interest?
Answer:
$0.231
Step-by-step explanation:
Given data
P= $77
r= 16%
t= 6 months= 0.5 years
For simple interest
A= P(1+rt)
A=77(1+0.16*0.5)
A= 77(1+0.08)
A= 77*1.08
A= $83.16
For compound interest
A=P(1+r)^t
A= 77(1+0.16)^0.5
A= 77(1.16)^0.5
A= 77*1.077
A= $82.929
The difference is
=83.16- 82.929
=$0.231

Answer:
1) Zero based on (-16·t - 2) is t = -1/8 second
2) Zero based on (t - 1) is t = 1 second
Step-by-step explanation:
The given functions representing the height of the beach ball the child throws as a function of time are;
y = (-16·t - 2)·(t - 1) and y = -16·t² + 14·t + 2
We note that (-16·t - 2)·(t - 1) = -16·t² + 14·t + 2
Therefore, the function representing the height of the beachball, 'y', is y = (-16·t - 2)·(t - 1) = -16·t² + 14·t + 2
The zeros of a function are the values of the variables, 'x', of the function that makes the value of the function, f(x), equal to zero
In the function of the question, we have;
y = (-16·t - 2)·(t - 1) = -16·t² + 14·t + 2
The above equation can be written as follows;
y = (-16·t - 2) × (t - 1)
Therefore, 'y' equals zero when either (-16·t - 2) = 0 or (t - 1) = 0
1) The zero based on (-16·t - 2) = 0, is given as follows;
(-16·t - 2) = 0
∴ t = 2/(-16) = -1/8
t = -1/8 second
The zero based on (-16·t - 2) is t = -1/8 second
2) The zero based on (t - 1) = 0, is given as follows;
(t - 1) = 0
∴ t = 1 second
The zero based on (t - 1) is t = 1 second
pls help me !! will mark brainliest... i just need you to solve for m<1 and m<7 !! thanks !!
Step-by-step explanation:
=( n-2)180
= ( 4 - 2 )180
= 360
So, 144 + 90 + m<2 +m<1 = 360
144 + 90 + 85 + m<1 = 360
319 + m<1 = 360
m<1 = 360 - 319
m<1 = 41
their is an unknown angle so let's call it x
let's find x first ( m<6=49)
x + m<6 = 180
x + 49 = 180
x = 180 - 49
x = 131
Now let's find m<7
m<7 + 38 + m<4 + x = 360
m<7 + 38 + 85 + 131 = 360
m<7 + 254 = 360
m<7 = 360 - 254
m< 7 = 106

Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos y = adjacent/ hypotenuse
cos y = 18/20
Take the inverse cos of each side
cos ^-1 (cos y) = cos^-1(18/20)
y =25.84193276
