Consider the following figure.
Decide if each similarity statement is true or false.
Determine the slope-intercept equation of a line with a slope of 3/2 that passes through (2, -1).
Answer:
[tex] \orange{ \bold{y = \frac{3}{2}x -4 }}[/tex]
Step-by-step explanation:
Slope of line (m) = [tex] \frac{3}{2} [/tex]
Line passes through the points [tex] (2,\:-1)=(x_1, \:y_1)[/tex]
Equation of line in point slope form is given as:
[tex] y-y_1 =m(x-x_1)[/tex]
Plug the values of m, [tex] x_1\: \&\: y_1[/tex] in the above equation, we find:
[tex]y - ( - 1) = \frac{3}{2} (x - 2) \\ \\ y + 1 = \frac{3}{2}x - \frac{3}{2} \times 2 \\ \\ y + 1 = \frac{3}{2}x -3 \\ \\ y = \frac{3}{2}x -3 - 1 \\ \\ \purple{ \bold{y = \frac{3}{2}x -4 }}\\ \\ [/tex]
This is the required equation of line in slope-intercept form.
Emily has sent 28 text messages so far this week
that is 20 % of the total number of text messages she is allowed in one week
what is the total number of text messages emily can send in one week?
Divide the amount she sent by the percentage she sent:
28/0.20 = 140
She can send 140 in one week.

Small- 12 oz for $3.95
Medium- 16 oz for $4.25
Large- 20 oz for $4.55
Answer:
large
Step-by-step explanation:
3.95 divided by 12 = 0.33
4.25 divided by 16 = 0.27
4.55 divided by 20 = 0.2275
the 20oz is the least unit price

4--9w^2
Can Someone help PLS
Answer:
Step-by-step explanation:
Use the identity: a² - b² = (a + b)(a- b)
4 - 9w² = 2² - (3w²)
= (2 + 3w)(2 - 3w)
Find the base of a triangle whose altitude is 12 cm and area is 96 cm
Given:
Altitude of a triangle = 12 cm
Area of the triangle = 96 sq. cm
To find:
The base of the triangle.
Solution:
The area of a triangle is
[tex]Area=\dfrac{1}{2}\times base\times height[/tex]
Putting Area = 96 and height = 12, we get
[tex]96=\dfrac{1}{2}\times base\times 12[/tex]
[tex]96=6\times base[/tex]
Divide both sides by 6.
[tex]\dfrac{96}{6}=base[/tex]
[tex]16=base[/tex]
Therefore, the base of the triangle is 16 cm.

Find the matrix product, if possible.
Answer:
below.
Step-by-step explanation:
The number of columns in the first matrix must equal to the number of rows in the second for multiplication to be possible.
Here first matrix has 3 columns and second one has 3 rows so POSSIBLE.
[ -8 2 2] { 3 }
[ 0 ]
[ -3]
= -8*3 + 2*0 + 2 * -3 = [-30] <-------- Answer.
Note a 1*3 matrix multiplied by a 1*3 matrix gives a 1*1 result.

f(x) = 3x - 3
g(x) = 4x + 5
find (f+g) (3)
Answer:
23
Step-by-step explanation:
(f + g)(3) = f(3) + g(3)
f(3) = 3(3) - 3 = 9 - 3 = 6
g(3) = 4(3) + 5 = 12 + 5 = 17
Then
(f + g)(3) = 6 + 17 = 23

Colton solved an equation incorrectly, as shown below:
Step 1: x - 13 = 26
Step 2: x = 26 - 13
Step 3: x = 39
Which statement best explains why Step 2 is incorrect in Colton's solution? (4
points)
He did not divide 26 by 13.
He did not multiply 26 by 13.
O He did not subtract 13 from 26.
He did not add 13 to 26.
Answer:
He didn't add 13 to 26
Step-by-step explanation:
he would need to add -13+13 to get rid of it. and add 13 on the other side 13+26
He added instead of subtracting. The answer is the first.

Answer:
$28
Step-by-step explanation:
1/2lb of cheese is 3.50, so 1lb must be $7. If you want 4lbs, simply multiply by 4, (7*4), which is $28

what is the measure of the base angle,x, of the isosceles triangle shown below? round your answer to the nearest tenth of a degree.
Answer:
x ≈ 49.7°
Step-by-step explanation:
Since, the given triangle is an isosceles triangle,
Two sides having measure 17 units are equal.
Opposite angles of these equal sides will be equal.
Measure of the third angle = 180° - (x + x)°
By sine rule,
[tex]\frac{\text{sinx}}{17}=\frac{\text{sin}(180-2x)}{22}[/tex]
[tex]\frac{\text{sinx}}{17}=\frac{\text{sin}(2x)}{22}[/tex] [Since, sin(180 - θ) = sinθ]
[tex]\frac{\text{sinx}}{17}=\frac{2(\text{sin}x)(\text{cos}x)}{22}[/tex]
[tex]\frac{\text{sinx}}{17}=\frac{(\text{sin}x)(\text{cos}x)}{11}[/tex]
[tex]\frac{1}{17}=\frac{(\text{cos}x)}{11}[/tex]
cos(x) = [tex]\frac{11}{17}[/tex]
x = 49.68°
x ≈ 49.7°

Solve for x. Round answer to the nearest tenth (0.1).
Answer:
x = 9.9
Step-by-step explanation:
This is a isosceles triangle, with sides measurements (1 , 1 , √2), and the angles being (45° - 45° - 90°). Note that the side measurements of 1 is opposite of that of a 45°, while the measurement of √2 is opposite of that of 90°.
In this case, multiply. The side measurement of 1 has 7.
1 x 7 = 7
In the same, you must multiply 7 with √2
x = 7 * √2 = 7√2.
√2 = ~1.414
7 x 1.414 = 9.898
Round to the nearest tenth:
9.898 rounded to the nearest tenth = 9.9
x = 9.9
~
Answer:
9.9 is your answer
Step-by-step explanation:
by using Pythagoras law
p²+b²=h²
7²+7²=x²
x=√{2×49)=7√2or 9.9 is your answer
Find the measure of CB.
Answer:
I'm Pretty Sure Its 40.
Step-by-step explanation:
Answer:
CB = 20.
Step-by-step explanation:
If the triangle is Isosceles, assuming that <D = <B according to the markings, CB must be 20 since 32 is the greatest side and therefore the hypotenuse, 20 is the smaller side and therefore either opposite or adjacent. Given that two sides must be the same, since CB is opposite of angle D which is congruent to angle B, CB = side opposite of angle B = 20.
2/5+7/15 in its simplest form
Answer:
13/15
Step-by-step explanation:
First convert the fractions to have a common denominator
2/5 = x/15
Cross multiply
2 × 15 = 5 × x
30 = 5x
Divide both sides by 5 to isolate the variable
30 ÷ 5 = x
6 = x
Plug x into the new fraction
6/15
Now add this to the other fraction
6/15 + 7/15
Only add the numerators. The denominators will remain the same number
6 + 7 / 15
13/15
It cannot be reduced anymore so this is simplest form
Martina started with 228 boxes of cookies and sold the same number each day for 4 days. After 4 days of selling, she was left with 100 boxes of cookies. Enter the slope of the line representing the change in Martina's inventory of cookies over this period of time.
Answer:
[tex]m = -32[/tex]
Step-by-step explanation:
Let x = days and y = box of cookies
So, we have:
[tex](x_1,y_1) = (0,228)[/tex] -- When she started
[tex](x_2,y_2) = (4,100)[/tex] --- After 4 days
Required
Determine the slope
The slope (m) is calculated using:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{100 - 228}{4 - 0}[/tex]
[tex]m = \frac{-128}{4}[/tex]
[tex]m = -32[/tex]
The slope is -32
