Answer:
Step-by-step explanation:
height of a triangle=4x-1
base=5x+2x-3
=7x-2
area of triangle=base*height/2
=(7x-2)(2x-3)/2
=7x*2x-7x*3-2*2x+2*3/2
=14x^2+21x-4x-6/2
=14^2+17x-6/2
area of rectangle=l*b
(7x-2)(4x+1)
7x(4x+1)-2(4x+1)
4x*7x+7x*1-2*4x-2*1
=28x^2+7x-8x-2
=28x^2-x-2
area of shaded part=area of rectangle-area of triangle
=[tex](28x^2-x-2 )-\frac{14x^2+17x-6}{2}[/tex]

X - 3y = -13
3x + 7y = 25
Answers
Answer:
Step-by-step explanation:
x - 3y = -13
x = -13 + 3y
3 * (-13 + 3y) + 7y = 25
-39 + 9y + 7y = 25
16y = 64
y = 4
3x + 7 * 4 = 25
3x = -3
x = -1

Mrs. Newcomer went to Giant for groceries. She paid $6 for 2 pounds of grapes.
How much would 7 pounds of grapes cost?
Answers
Explanation:
1.) Find the unit rate of dollars per pound:
$6 divided by 2 = $3
Unit rate is $3 per pound of grapes
2.) Multiply the unit rate per pound by 7 pounds of grapes:
$3 x 7 = 21
So she will pay 21$ for 7 pounds of grapes.

find the angle r show ur work
Answers
Answer:
The measure of angle R is 112 degrees
Step-by-step explanation:
Using the given markings, we can see that we have an isosceles triangle
so RT is also 3x-2
Mathematically, the sum of the interior angles of a triangle is 180:
Thus;
9x + 4 + (3x-2) + (3x-2) = 180
9x + 3x +3x + 4-2-2 = 180
15x = 180
x = 180/15
x = 12
Recall; Angle R is 9x + 4
= 9(12) + 4 = 108 + 4 = 112

draw and label a line a line segment a ray and an angle
Answers
Answer and Step-by-step explanation:
Everything is in the picture.
Lines are forever, so they have an arrow at each end.
Line segments have a dot at each end, so they don't go on forever.
A ray has a dot on one end and an arrow on the other, so one side goes on forever.
An angle can be acute, right, or obtuse.

how do you find x in this? I need help asap!!
Answers
Answer:
Step-by-step explanation:
According to the theorem, the angle measuring 110 is one-half the measure of the arc it intercepts. That means that the major arc (this arc of which I'm speaking) measures 110 * 2 = 220.
Since the outside of a circle, regardless of how big or small the circle is, has a degree measure of 360, then x = 360 - 220 so
x = 140°

what is the probability of rolling a number that is greater than 4 on a number cube?
a.) 1/6
b.) 1/3
c.) 1/2
d.) 2/3
Answers
=========================================================
Explanation:
E = event space = {5,6}
The event space represents the set of all things we want to happen: namely rolling a 5 or a 6, since they are larger than 4.
S = sample space = {1,2,3,4,5,6}
The sample space is the set of all possible outcomes, whether we want them to happen or not. We have 6 possible outcomes.
Divide the number of items in each set
n(E) = 2
n(S) = 6
probability = n(E)/n(S) = 2/6 = 1/3
There's a 1 in 3 chance of rolling a number greater than 4.

Gillian swears her computations for the
following equations prove they do not
intersect. Her brother who just finished
learning about intersecting lines told her they
definitely intersect because the slopes are
different. Gillian remembered that logic from
class and then decided she needed to be able
to prove intersection by using algebra.
Although there are multiple strategies, how
might she prove intersection without graphing
of the following equations?

Two lines [tex]a_1x+b_1y=c_1[/tex] and [tex]a_2x+b_2y=c_2[/tex] will intersect when
[tex]\dfrac{a_1}{a_2}\neq \dfrac{b_1}{b_2}[/tex]
