Answer:
-15
Step-by-step explanation:
10 x -15 = -150
-150 + 50 = -100

Julio says, "If you subtract 14 from my number and multiply the difference by - 4, the result is
- 28." What is Julio's number?
Julio's number is
Answer:
x = 21
Step-by-step explanation:
let the number be x
-4(x-14) = -28
-4x + 56 = -28
-4x = -28 - 56
-4x = -84
x = 84/4 = 21
which inequality represents all values of x for which the quotient below is defined? ✓15(x-1) ÷ ✓2x^2
9514 1404 393
Answer:
C. x ≥ 1
Step-by-step explanation:
The content of the radical must be non-negative in both cases. The square of x is already non-negative for any x.
15(x -1) ≥ 0
x -1 ≥ 0 . . . . divide by 15; next, add 1
x ≥ 1 . . . . . matches choice C
Answer:
Step-by-step explanation:
x > 1

two square are congruent ,if they have same _____
Answer:
Two squares are congruent if they have the same side length
Step-by-step explanation:
The dimensions of a square are the side length of the square and in a square, all sides are equal
Therefore, given that two quadrilaterals are squares, and the side length of each of the given quadrilateral are equal, the quadrilateral are said to be congruent.
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)
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

Answer:
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!

PLEASE HELP ME ASAP!!! THIS IS DUE TODAY!!!! I need to find y-intercept and slope using (-18,4)&(-7,4)
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
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

18 football teams who play each other twice. how many matches are played
Answer:
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)
