Answer:
the answer is either a or c
Step-by-step explanation:
X is the slope
3 is the Y intercept
The (greater than equal to) sign means that the line will be solid
I dont remember which way the shaded area goes. the direction the greater than symbol is faceing has somthing to do with that.
Did this last year for my freshman year. sorry i cant help more
When given a graph or table, you first want to figure out the slope. Look at the graph or table, and see how much does y change when x change in a certain amount? You want it as a rise/run so if x increases 2 when y increases 3 then the slope would be 3/2.
Next, you want to find the y intercept.
Look at the y value when x is 0. If the y is -2 when x=0, then b=-2.
When given its graph, find a y value when x is 0. If the y is 4 when x=0 then b=4
42 is 30% of 140
This is evident because, 42÷140=0.3
And you should hopefully know your place values right?
So then we know that 3 is in the10ths place and so to change the decimal to a fraction we get 3/10 which then changed to a percent, is equal to 30.
Long story short, 42 is 30% of 140 :)
Answer:
x ≈ 6.5
Step-by-step explanation:
We have the epresion 
and we want to find the value of 
.
Let's do it step-by-step
Step 1. Multiply both sides of the equation by 20
Step 2. use the reflexive property of equality: if 
then 
Step 3. Using a calculator we get that 
. Replacing that value we get
x ≈ 6.5
We can conclude that the value of x is approximately 6.5
Answer:
$950
Step-by-step explanation:
x+70=1020 so subtract 70 from both sides
x=950 cost of dryer
1020-950=70 washer is 70 more than dryer
