Answer:
<h2>x = -1, y = 10 → (-1, 10)</h2>
Step-by-step explanation:

Discounted by 25% means he paid 75% of the original price:
80 x 0.75 = $60
Now multiply the sale price by 1 + tax rate:
60 x 1.05 = 63
He paid $63 total.
Answer:
5.1 cm
Step-by-step explanation:
(Probable) Question;
Given a circle with center <em>O</em> and radius 2.4 cm.<em> P</em> is a point on the tangent that touches the circle at point <em>Q</em>, such that the length of the tangent from <em>P </em>to <em>Q</em> is 4.5 cm. Find the length of OP
The given parameters are;
The radius of the circle with enter at <em>O</em>,
= 2.4 cm
The length of the tangent from<em> P</em> to the circle at point <em>Q, </em>
= 4.5 cm
The length of OP = Required
By Pythagoras's theorem, we have;
² =
² +
²
∴
² = 2.4² + 4.5² = 26.01
= √26.01 = 5.1
The length of OP = 5.1 cm
37=10+4.50x
x=number of students needed to make $37
37=10+4.50x
-10 -10
27=4.50x
/4.50 /4.50
6=x
She needs to 6 students to make $37 for an hour.
Hope it helps!
D) starting amount in his savings account.
in the linear equation the y intercept is the starting point when x is zero, that means that at the starting balance he had 1000 in the bank.
