Answer:
A
Step-by-step explanation:
since both equations express y in terms of x we can equate the right sides
x + 7 = - 2x + 19 ( add 2x to both sides )
3x + 7 = 19 ( subtract 7 from both sides )
3x = 12 ( divide both sides by 3 )
x = 4
substitute x = 4 into either of the 2 equations for y
y = x + 7 ⇒ y = 4 + 7 = 11
solution is (4, 11 )
ANSWER: $4.95
EXPLANATION:
So it’s asking us to find out if $4.95 dollars is more than 5.75% of 78.99.
So we need to find 5,75% of 78.99
To find percentage turn the percent into a decimal.
5.75% become 0.575
Now we have 0.575 x 78.99
That is 45.41925
Move the decimal over again and you get 4.541925
Round to the nearest hundredth to get
$4.54
$4.54 < $4.95
So the answer is &4.95
Based on the distance formula, the distance between points (3, 7) and (x1, y) is: . SO, it is TRUE.
<h3>What is the Distance Formula?</h3>
The distance formula which can be applied to find the distance between two coordinate points is: .
Given the points:
(x1, y1)
(3, 7) = (x2, y2)
Substitute
Therefore, the statement that says the distance between points (3, 7) and (x1, y) = , is TRUE.
