Can someone plzzz tell me if #14. b. is right plzz
Answer:
14b.) RS = 60; ST = 36; RT = 96
Step-by-step explanation:
Since you have correctly solved for y = 7, all you need to do for b is to plug in y.
RS = 8(7) + 4 = 60
ST = 4(7) + 8 = 46
(You can add RS and ST or plug in for y for RT)
RT = 15(7) - 9 = 96

Answer:
the 4th answer : a = 3 and b = sqrt(3)
Step-by-step explanation:
remember that i = sqrt(-1).
so, when you "take out" -1 of -3, you get 3.
sqrt(-3) = sqrt(3×-1) = sqrt(3)×sqrt(-1) = sqrt(3)i

Alex saved x dollars.
Ethan saved 1/3 more than that.
Write an equation for the amount of money Ethan saved. Be sure to use decimals in your
equation.
What is the value of x? Then determine the measure of each angle.
Answer:
x = 14° || each angle has 108°
explanation:
first we need to find the total interior angle of this shape:
formula: ( n - 2 ) * 180 ..............where n is the number of sides
( 5 -2 ) * 180
540°
if all sides in the shape are equal, they must have same angle of 9x -18
5 ( 9x -18 ) = 540°
9x -18° = 108°
9x = 108° + 18°
9x = 126°
x = 14°
So each angle has: 9x - 18
9(14) - 18
108°

A person overcharges his bank account by spending the same amount of money each day. After five days of overcharging his bank account, he is $100.00 dollars in debt. Therefore, each day, his account balance changed by how much?
Answer:
20
Step-by-step explanation:
Why? because 100$ in 5 days is he spent the same much each day then it's 20 because 20 x 5=100
20 x 1=20
20 x 2=40
20 x 3=60
20 x 4=80
20 x 5=100

p + 333 = 350
Answer:
17
Step-by-step explanation:
350-333 = 17
p = 17
Or...
Subtract 3 from both sides of the equation
p+333=350
+333−333=350−333
p = 17
Answer:
p=17
Step-by-step explanation:
p+333 = 350 (subtract 333 on both sides)
350-333 = 17
p = 17

Answer: Choice D
Explanation:
I'll use the point-slope form to get the following
[tex]y - y_1 = m(x - x_1)\\\\y - 1 = \frac{3}{4}(x - (-4))\\\\y - 1 = \frac{3}{4}(x + 4)\\\\y - 1 = \frac{3}{4}x + \frac{3}{4}*4\\\\y - 1 = \frac{3}{4}x + 3\\\\y = \frac{3}{4}x + 3 + 1\\\\y = \frac{3}{4}x + 4 \ \ \text{... matches with choice D}\\\\[/tex]
You should find that plugging x = -4 into equation D will lead to y = 1 as a way to confirm the answer.
Answer:
D
Step-by-step explanation:
m = 3/4
point: (-4, 1)
We can use the slope-intercept form. We know one point, so we can use its coordinates for x and y. We also know the slope, so we use the slope for m. Then we solve for b.
y = mx + b
Substitute m with the slope.
y = (3/4)x + b
Use the x-coordinate of the given point for x and the y-coordinate of the given point for y.
1 = (3/4)(-4) + b
Solve for b.
1 = -3 + b
b = 4
Now that we know the value of b, we can write the equation of the line.
y = mx + b; m = 3/4; b = 4
y = 3/4 x + 4
Answer: D

a) m/s
b) km/h.
Answer:
A.) 9.09
B.) 1.1
Step-by-step explanation:
The velocity in meters per second is equal to the distance in meters divided by time in seconds.
100 meters/ 11 seconds
100 meters is .1 kilometers
.1 kilometers x11 seconds =1.1

Answer:
angle x= 136
Step-by-step explanation:
angle on straight line =180
so we do 180 - 96 (angle y)=84
then:
angles in a triangle add up to 180
we do
84 (inside the triangle next to angle y) + 52 (angle z)= 136
180 (all angles in triangle) - 136 (angle y and z)=44
Now we know that the angle inside the triangle next to Angle x is 44
Angles on straight line =180
180-44= 136
angle x = 136Answer:
Step-by-step explanation:
triangle first:
= y=96
= z=52
= so , 180-96=84
= so, angle b = 84
= the corresponding side should be equal so, angle c = 84
= so x. = 180 - 84
= x = 96
= so , x = 96
so , this is the triangle theory yehhaaaaa

this is substitution I really need help
Answer:
x = 1
y = 0
Step-by-step explanation:
You did a great job solving one of the equations for a single variable. You solved for x. But what your paper shows is that...it jind of looks like you were going to substitute the 2y+1 into y. BUT you need to substitute it into x.
-4x + 3y = -4
x = 2y + 1
Fill in 2y + 1 into x in the first equation.
-4(2y+1) + 3y = -4
Now you have an equation in one variable. There are only y's in this equation. Next, distribute.
-8y - 4 + 3y = -4
combine like terms.
-5y - 4 = -4
add 4 to both sides.
-5y = 0
divide by -5
y = 0
It's okay that it cam out to be zero. Its fine!
y=0
Put it back in one of the original equations to find x.
x = 2y + 1
x = 2(0) + 1
x = 1
The solution is
x=1
y=0
You can write this as an ordered pair.

The water jug for a basketball team was 7/8 full of water after the game the 8 players poured out 3/5 of the water in the jug. How much water is still there
The water left in the jug after the players poured out some water is 11/40
How to subtract fractionQuantity of water in the jug = 7/8Water poured out of the jug = 3/5Water remaining = Quantity of water in the jug - Water poured out of the jug
= 7/8 - 3/5
= (35-24) / 40
= 11/40
Therefore, the water still left in the jug us 11/40
