Answer:
a. y= 0.613x - 4.141
Step-by-step explanation:
y= ~ -4 when x= 0 so that will be our y-intercept.
so our option would be either A or D
if you look closely, the x goes up when y goes up, which means the slope is a positive
Step 1: –10 + 8x < 6x – 4
Step 2: –10 < –2x – 4
Step 3: –6 < –2x
Step 4: ________
What is the final step in solving the inequality –2(5 – 4x) < 6x – 4?
x < –3
x > –3
x < 3
x > 3
Answer:
The process of solving the inequality will be: -2(5 - 4x) < 6x - 4 8x - 10 < 6x - 4 -6 < -2x x > 3 This is in accordance to the rule of solving inequalities which states that whenever we multiply or divide by a negative number while solving an inequality, we must reverse the inequality sign.Candace surveyed every 10th student that walked onto campus. She asked them if they were planning to read any books over the summer. She ended up surveying 50 people. 15 of them said yes. If there are 1000 students at her school, predict about how many will be reading over the summer.
Answer:
not whoever wrote this question. every 10th person is surveyed. she surveyed 50 people. that mean 500 people and 50 surveyed people. then at the end the teacher said there is 1000 students. your teacher wrote you a bad question with no right answers.
Find m
A.)38
B.)22
C.)52
D.)12
Answer:
x =12
Step-by-step explanation:
The two angles add to 90 degrees
4x+4 + 5x-22 = 90
Combine like terms
9x - 18 = 90
Add 18 to each side
9x -18+18 = 90+18
9x = 108
Divide each side by 9
9x/9 = 108/9
x =12
Answer:
C.) 52°
Step-by-step explanation:
find x first
4x + 4 + 5x - 22 = 90
9x - 18 = 90
9x = 108
x = 12
plug it into the expression
4(12) + 4
= 48 + 4
= 52°
Linea 6: cada 45 minutos linea 15: cada 15 minutos linea 10: cada 30 minutos rapidos por autopista: cada 90 minutos ¿coinciden en algun momentos todas las lineas, menos el rapido? Explica tu respuesta
Answer:
Las tres líneas coinciden cada 90 minutos, es decir, al mismo tiempo que pasa el Rápido, con lo cual en ningún momento coinciden todas las líneas menos el Rápido.
Step-by-step explanation:
Dado que la Línea 6 pasa cada 45 minutos, la Línea 15 pasa cada 15 minutos, la Línea 10 pasa cada 30 minutos, y los Rápidos por autopista pasan cada 90 minutos, para determinar si coinciden en algún momento todas las líneas, menos el rápido, se deben realizar los siguientes cálculos:
Línea 6 = 00:45, 01:30, 02:15, 03:00
Línea 15 = 00:15, 00:30, 00:45, 01:00, 01:15, 01:30, 01:45, 02:00, 02:15, 02.30, 02:45, 03:00
Línea 10 = 00:30, 01:00, 01:30, 02:00, 02:30, 03:00
Rápido = 01:30, 03:00
Así, como puede verse, las tres líneas coinciden cada 90 minutos, es decir, al mismo tiempo que pasa el Rápido, con lo cual en ningún momento coinciden todas las líneas menos el Rápido.

Step-by-step explanation:
find the value of x please
Answer:
2x +5x-20+3x=180(angle of triangle)
10x-20=180
10x=180+20
10x=200
x=200/10
x=20
Answer:
[tex]x = 20[/tex]
Step-by-step explanation:
Angles in a triangle is added up to 180 degrees
So, You can simply Solve it like this
[tex]2x + 3x + 5x - 20 = 180 \\ 10x = 180 + 20 \\ 10x = 200 \\ \frac{10x}{10} = \frac{200}{10} \\ x = 20[/tex]
Hope this helps you.

Store a sells fabric for 3.00 per yard Store b sells packages of fabric for 3.00 The cost of fabric at either can be modeled by the function c(t)=3t where t is the number of yards of fabric at store a and t is the number of packages of fabric at store b The domain of c(t)=3t is all real numbers
Answer:
[tex]0 \le t < \infty[/tex]
Step-by-step explanation:
Given
[tex]c(t) = 3t[/tex]
Required
The domain
From the question, we understand that t represents number of yards/packages (depending on the store)
This means that:
[tex]t \ge 0[/tex] ---- the start value
[tex]t < \infty[/tex] --- the end value
Rewrite [tex]t \ge 0[/tex] as [tex]0 \le t[/tex]
So, we have: [tex]0 \le t[/tex] and [tex]t < \infty[/tex]
Hence, the domain is: [tex]0 \le t < \infty[/tex]
if f(x) = -4x+3 and g(x) = 3 +2x-4 find (f+g) (x)
Answer:
Please be careful with your typing [f(x)=-sqrt(x)+6 ... right? g(x)=-4*sqrt(x)-3 ... or -4*sqrt(x)+3 ... one or the other, right?
If so, you are dilating by a factor of 4, -1 versus -4 as multiplier of sqrt(x); and, translating up 3 units (6 versus 3) or 9 units (6 versus -3).
Step-by-step explanation:
Answer:
-2x+2
Step-by-step explanation:
f(x) = -4x+3 and g(x) = 3 +2x-4
Note what you put for g(x) simplifies to 2x-1
(f+g) (x) = -4x+3+ 3 +2x-4
Combine like terms
= -2x+2

Tristan records the number of customers who visit the store each hour on a Saturday. His data representing the first seven hours are 15, 23, 12, 28, 20, 18, and 23. How many customers visited the store during the eighth hour if the median number of customers per hour did not change?
16
19
20
23
Answer:
20
Step-by-step explanation:
The number of Customers that visited the store during the eight hour if the median number of customers didn't change is; C: 20
What is the Median?We are given the data representing the first seven hours as; 12, 15, 18, 20, 23, 23, 28. Here; n=7
Thus;
Median = (n + 1)/2 = (7 + 1)/2
Median = 4th term
Thus, the median is 20.
When one data is added, n = 8. Thus;
Median will be the average of the 4th and 5th term. Since the median does not change, it means that the median number of customers per hour is still 20.

What is the equation in point-slope form of the line passing through (−2, 1) and (4, 13)
Answer:
y = 2x + 5
Step-by-step explanation:
We have two points,
(-2,1) and
(4,13)
from which we can find the slope, m, where
m = (13-1)/(4--2) = 12/6 = 2
take any of the two points to form the point-slope form
y-y1 = m(x-x1)
y-13 = 2 (x-4)
y = 2x - 8 + 13 =2x+5
Check:
when x = -2, y = 2(-2)+5 = 1 checks.
What’s the equation for X?
Answer:
perimeter of rectangles = 2 ( l + b)
34 = 2 ( x + 2 + 3x - 4 )
34 = 2 ( 4x - 2 )
34 = 8x - 4
38 = 8 x
38/ 8 = x
thus , x = 4.75 inches
Answer:
x=19/4
Step-by-step explanation:
perimeter is the sum of all sides
so
perimeter given is 34 = (x+2)+(x+2)+(3x-4)+(3x-4)
34=8x-4
34=8x
x=34/8 which reduces to 19/4

This is so we can get the expression in a(r)^(n-1) form
a = 8/7 is the first term of the geometric sequencer = 2/7 is the common ratioNote that -1 < 2/7 < 1, which satisfies the condition that -1 < r < 1. This means the infinite sum converges to some single finite value (rather than diverge to positive or negative infinity).
We'll plug those a and r values into the infinite geometric sum formula below
S = a/(1-r)
S = (8/7)/(1 - 2/7)
S = (8/7)/(5/7)
S = (8/7)*(7/5)
S = 8/5
S = 1.6
