5x2y and 7xy2 are like terms.
True
False
Answer: False
The variable portions x^2y and xy^2 are slightly different, so that's why we don't have like terms here.
Answer:
False
Step-by-step explanation:
Like terms are those terms where they have the same variable
so here
5x2y variables are = 5x and 2y
7xy2 variables are = 7x and y2
you can observe that x variable is same but y variable is not same as 5x3y have 2y whereas 7xy2 have y2#
so the answer is FALSE

line r passes through on the same spot on the y axis as line z and also passes through the point (1,4). If the equation for line z is y= -2x + 3, what is the equation of line r
Answer:
r= x + 3
Step-by-step explanation:
They share the same y intercept so we can know the vertical shift up. The Y intercept of line z would be 3, so line r would share the intercept too. From this we can find that the slope would be one since moving one unit to the right also makes the equation go 1 unit up, from (0,3) to (1,4). This would mean that the equation of line r is r= x + 3
f(x) = (x - 5) (2x - 7) (7x - 3) has zeros at x = -3.5, x = 3/7, and x = 5.
what is the sign of f on the interval 3/7 < x < 5 ?
1. f is always positive on the interval.
2. f is always negative on the interval.
3. f is sometimes positive and sometimes negative on the interval.
The function f(x) will be sometimes positive and sometimes negative on the interval so option (3) will be correct.
What is a function?
A certain kind of relationship called a function binds inputs to essentially one output.
In other terms, a function is a relationship between variables, and the type of relationship that exists between the variables defines the function, such as y = sinx and y = x +6.
Given function is
f(x) = (x - 5) (2x - 7) (7x - 3)
The term (x - 5) will be negative if x < 5.
The term (2x - 7) will be negative if x<3.5
Let's say if x = 4 then (x - 5) will be negative but (2x - 7) will be positive and hence overall value will be negative.
But if x = 3 then (x - 5) will be negative and (2x - 7) will also be negative and hence overall value will be negative
Hence the function f is sometimes positive and sometimes negative on the interval.

Step-by-step explanation:
Jacob earned $80 babysitting and deposited the money into his saving account. The next week he spent $85 on video games. Use integers to describe the weekly changes in Jacob's savings account balance.
Answer:
Net change in money: decrease of $5
Step-by-step explanation:
supposing Jacob started with x dollars:
He gained $80 from babysitting: x+80
Lost 85: x + 80 - 85
--> x - 5
Therefore, at the end of the week, Jacob lost 5 dollars

Answer:
x = 16.4
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opp / hyp
sin 66 = 15/x
x sin 66 = 15
x = 15/sin 66
x=16.41954
Rounding to the nearest tenth
x = 16.4

d. 292.5 in.
c. 32 in?
a.
Answer:
a, a, d
Step-by-step explanation:
44
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
Here b = 10 and h = 9 , then
A = [tex]\frac{1}{2}[/tex] × 10 × 9 = 5 × 9 = 45 in² → a
45
The area (A) of a parallelogram is
A = bh ( b is the base and h the perpendicular height )
Here b = 2 and h = 4 , then
A = 2 × 4 = 8 m² → a
46
A = bh ( with b = 4 and h = 10 )
A = 4 × 10 = 40 m² → d

1. Find the measure of angle R.
Answer:
the first option 40 degrees
Step-by-step explanation:
the outward angle at the center of the circle between the two tangential points is 220 degrees.
that means that the inward angle between them is
360 - 220 = 140 degrees.
now consider that there is a triangle between the center of the circle, one of the tangential points (it does not matter which one, as the upper and the lower triangles are equal) and the point R.
we know the angle at the tangential point : 90 degrees by definition (otherwise it would not be a tangent).
and we know the angle at center of the circle, which is half of the inward angle
140 / 2 = 70 degrees.
and at point R we have half of the full angle R.
we can calculate that half by using the fact that the sum of all angles in a triangle is always 180 degrees.
180 = 90 + 70 + R/2
180 = 160 + R/2
20 = R/2
R = 40 degrees

Step-by-step explanation:
if π<α<2π and cotα<0, then 1.5π<α<2π. It means, that cosα>0 and tanα<0.
1) tanα=1/cotα; ⇒tanα= -7/24;
2) [tex]cos\alpha =\frac{1}{\sqrt{1+cot^2\alpha }}}; \ cos\alpha =\frac{7}{25}.[/tex]

Sandra is choosing an Internet service provider.
• Smart Dot Company costs $12 per month plus $0.50 for each hour of Internet used.
• Communication Plus costs $2.50 for every hour of Internet used.
a. Create an equation to represent the cost of using the internet with each company. (2 marks) Let C represent the cost of using internet in any month.
Let t represent the number of hours used
Smart Dot, multiply the cost per hour by number of hours (t) and add to the monthly fee:
C = 0.50t + 12
Communication plus: Multiply the cost per hour by number of hours (t)
C = 2.50t
