Are the expressions -0.5(3x + 5) and -1.5x + 2.5 equivalent? Explain why or why not.
help answer ASAP WILL GiVE BRAINLIEST
Answers
Answer:
Step-by-step explanation:
Expanding the first statement using the distributive property yields -1.5x - 2.5. The two formulations are not equal because the constant term does not have the same sign as the second expression. Furthermore, if you replace x with a value and evaluate each equation, the results will not be equal.
PLEASE HELP ME ASAP!!! THIS IS DUE TODAY!!!! I need to find y-intercept and slope using (-18,4)&(-7,4)
Answers
Answer:
can someone please help me with this

Step-by-step explanation:
Answer:
y=4
Step-by-step explanation:
I use the slope formula
y2-y1/x2-x1
4-4=0
/
-18-(-7)=11
=0
Finding the y-intercpt
I use (-7,4). Since you know the slope-intercpet form which is y=mx+b
y=mx+b
4=0(-7)+b
4=0+b ( subtract zero on both sides)
4=b
Thus, the equation of the line is y=4.

a rectangle has a perimeter of 22 feet. the width is 5 feet less than the length. find the length and width of the rectangle
Answers
Answer:
the length is 8ft
the width is 3ft
Step-by-step explanation:
Step one:
given
perimter= 22ft
let the length be x
width = x-5
Step two
the expression for the perimeter of a rectangle is
P=2L+2W
substituting our data
22= 2(x)+2(x-5)
open brackets
22=2x+2x-10
collect terms and solve for x
22+10=4x
32=4x
divide both sides by 4
x= 32/4
x= 8ft
the length is 8ft
the width = x-5= 8-5= 3ft
Stella solves the following system of equations using the substitution method.
y=−4x−65x−y=10
What is the single-variable equation she solves after substituting?
5x−4x−6=10
5x−(−4x−6)=10
5x+10=−4x−6
5x+10=−(4x−6)
Answers
Answer:
5x-(-4x-6) = 10
Step-by-step explanation:
Given the expression
y=−4x−6 ..... 1
5x−y=10... 2
To get the required equation we will substitute equation 1 into 2
5x-y = 10
5x-(-4x-6) = 10
5x+4x+6 = 10
9x+6 = 10
9x = 4
x = 4/9the required equation is 5x-(-4x-6) = 10
Answer:
5x - (-4x - 6) = 6

Total number of matches = 306 matches
Step-by-step explanation:
Given:
Total number of team = 18
Per team number of play = 2
Find:
Total number of matches
Computation:
Total number of matches = [(Total number of team x 2)(Total number of team -1)]/2
Total number of matches = [(18 x 2)(18-1)]/2
Total number of matches = 612 / 2
Total number of matches = 306 matches

The transformation from point (-3, -3) to point (4, -5) is the same transformation from point (-1, -7) to the missing point.
Let's find the transformation from point (-3, -3) to point (4, -5).
x: 4 - (-3) = 7
y: -5 - (-3) = -2
Now we apply a transformation of 7 in x and -2 in y to (-1, -7).
(-1 + 7, -7 + (-2)) = (6, -9)
Answer: (6, -9)

So to graph using a table, the first step is...well... make a table. so you have a column of x and y. under the x column write down a bunch of values you would like to test. I am going to test -2 through 2.
x | y
-2|
-1|
0 |
1 |
2 |
Next, we have to plug each of those values into the equation y=2x to see what the corresponding y value is.
when x=-2 y=2(-2)=-4, when x=-1 y=2(-1)=-2, and so on...
x | y
-2|-4
-1|-2
0 |0
1 |2
2 |4
Next, graph those points on a coordinate plane. Each row on the table is a point on the graph, (x,y). Hope that helps!
