b/50
Answer:
b = 130°
Step-by-step explanation:
angles b and 50° are supplementary angles so their sum is 180°.
b = 180° - 50° = 130°

Which line has the same slope as the lone passing through (-4,-1) and (-1,-7)
1) 6x+3y=5
2)y=-1/2x-7
3)y=-2
Answer:
1) 6x+3y=5
Step-by-step explanation:
1) First, find the slope of the line passing through (-4, -1) and (-1, -7). Use the slope formula [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Substitute the x and y values of the two points into the formula and solve:
[tex]m = \frac{(-7)-(-1)}{(-1)-(-4)} \\m = \frac{-7+1}{-1+4} \\m = \frac{-6}{3} \\m = -2[/tex]
So, the slope is -2.
2) Now, identify the slopes of the lines in the options. We already know the slope of [tex]y = -\frac{1}{2} x-7[/tex] is [tex]-\frac{1}{2}[/tex] since it is in slope-intercept form. y = -2 must have a slope of 0 since it's horizontal, and all equations with the format of y = a number are horizontal.
To find the slope of [tex]6x + 3y = 5[/tex], isolate y to put the equations into slope-intercept form ([tex]y = mx + b[/tex] format), and whatever the coefficient of the x-term is will be the slope.
[tex]6x + 3y = 5\\3y = -6x+5\\y = -2x + \frac{5}{3}[/tex].
So, the slope of the first option is -2. It matches the slope we calculated in the first step, so that must be the answer.

I got this right on the edmentum test if this is wrong then I'm sorry.
Please help me ASAP..
Answer:
x = -8
Step-by-step explanation:
5(x - 1) = -45
5x - 5 = -45
add 5 to each side of the equation:
5x = -40
divide both sides by 5:
x = -8
Noveli has a credit limit of $3,000 on her credit card.
She had a previous balance of $55.60 from last month on her credit card.
She made a payment of $310
She made purchases for the month that totaled $409.00
She had a finance charge of $11.75
What is Noveli's available credit on her credit card?
Answer:
Your credit card issuer will calculate your finance charge for you in your bill, but ... when you're charged one, so there's not necessarily a need to calculate it on your ... With most credit cards, the billing cycle is shorter than a month, for example, ... transactions made on your credit card in the current or previous billing cycle.
Step-by-step explanation:
You have collected data on the average weekly amount of studying time (T) and grades (G) from peers at your university. Changing the measurement from minutes into hours has the following effect on the correlation coefficient:
a. cannot be computed since some students study less than an hour per week
b. does not change the rTG
c. decreases the rTG by dividing the original correlation coefficient by 60
d. results in a higher rTG
Answer:
b. does not change the rTG
Step-by-step explanation:
If the average weekly amount of studying time and Grade are compared such that a certain correlation Coefficient value is obtained, changing the unit of measurement of any of the variables, will not affect the value of the correlation Coefficient most notably because the value of R, correlation Coefficient is a normalized or standardized value that ranges between - 1 and 1 and hence, resistant to unit changes in the compared variables. Hence, Correlation coeffient for the rate of study and grade obtained will not change even if rate of study is measured in hour.
Answer:
b. does not change the rTG

19 Jaime bounces a basketball 30 times in 25 seconds. At that rate,
approximately how many times will she bounce the ball in 65 seconds?
A 78
B 80
C 55
D 64
Answer:
A.78
Step-by-step explanation:
[tex]\frac{30}{25sec}[/tex] -----> [tex]\frac{78}{65sec}[/tex] (scale by 2.6)
You cant get the answer by following these steps.
1. To find out how much we must increase with our scaling we must divide the denominators.
[tex]\sqrt[25]{65}[/tex]= 2.6
2. Then, we do the scaling. Multiply the numerator and the denominator by 2.6.
num- 30 x 2.6= 78.0 (DONT FORGET UR DECIMALS)
dem- 25 x 2.6 = 65
3. Now you have your answer and all you need to do is show it in fraction form as seen below the words "step by step explanation"

35=11x. i need help
Answer:
x= 35/11
Step-by-step explanation:
steps
35 = 11x
swich sides
11x = 35
Divide both sides by 11
11x/11 = 35/11
simplify
x = 35/11

Solving the following simultaneous equations, 4x - 5y = 17 and x - 5y = 8,
{4x - 5y = 17
{x - 5y = 8
{x = 5y + 8
{4(5y + 8) - 5y = 17
{x = 5y + 8
{20y + 32 - 5y = 17 | - 32
{x = 5y + 8
{15y = -15 | : 15
{y = -1
{x = 5 * (-1) + 8
{x = 3
{y = -1

Find the value of x.
899
46
X
Answer:
I think it's 45.
Step-by-step explanation:
46 + 89 = 135
adding all the angles of a triangle will always equal 180.
180 - 135 = 45
the last angle is 45.
