What is the value of 3/8 X -4.5 when X= 0.4
Answer:
-4.35
Step-by-step explanation:
3/8 X -4.5
3/8 (0.4) - 4.5
0.15 - 4.5
= -4.35
Answer:
-4.35
Step-by-step explanation:
You multiply three eights times .4 which gives you .15, then you subtract that from 4.5 which gives you 4.35

Step-by-step explanation:
2(x+7)=72 no, because this only changes the value on the right side. so this equation is not about the same equality anymore.
x+7=18 yes, because both sides were transformed by the same operation (division by 2). the equality is still maintained.
2x+7=36 no, because 2x+7 is NOT equal to 2(x+7). resolving 2(x+7) is 2x+14.
x+14=36 no, because again, x+14 is NOT equal to 2(x+7).
(2×x) + (2×7) = 36 yes, because the left side is a valid transformation of 2(x+7).
2x+14=36 yes, because the left side is a valid transformation of 2(x+7).

Given f(x) = x^2 – 5x + k, and the remainder when f(x) is
divided by x - 7 is 34, then what is the value of k?
Step-by-step explanation:
f(7) = 34
7² -5(7) +k = 34
49-35+k =34
14+k = 34
k = 34-14
k = 20
__________
[tex] \: [/tex]
f(x) = x² - 5x + k
f(7) = 34
Soo :
f(7) = 34
(7)² - 5(7) + k = 34
49 - 35 + k = 34
14 + k = 34
k = 34 - 14
k = 20✔

(2x + 1)2 − 4x(x − 1) = 7
Answer:
[tex](2x + 1)^{2} - 4x(x - 1) = 7 \\ (2x + 1)(2x + 1) - 4 {x}^{2} + 4x = 7 \\ 4 {x}^{2} + 4x + 1 - 4 {x}^{2} + 4x = 7 \\ 8x + 1 = 7 \\ 8x = 7 - 1 \\ 8x = 6 \\ \\ x = \frac{6}{8} \\ \\ x = \frac{3}{4} \\ \\ x = 0.75[/tex]

If you know two angle measures of a triangle in spherical geometry, can you always find the measure of the third angle? Explain.
A. Yes; the angle measures of a triangle always sum to 180.
B. Yes; the angle measures of a triangle always sum to 270 in spherical
geometry.
C. No; the sum of angle measures in spherical geometry is always greater than
180, but there is not a particular number they must sum to.
D. No; the sum of angle measures in spherical geometry is always greater than
270, but there is not a particular number they must sum to.
When two angle measure of a triangle are given in spherical geometry: The sum of angle measures in spherical geometry is always greater than 180, but there is not a particular number they must sum to. Choice C (No) is correct
According to the question;
Two angle measures of a triangle in spherical geometry are given.However, unlike in plane geometry where affirmatively, the sum of angles in a triangle is equal to 180°.
In spherical geometry;
The totality of the angles of a triangle on a sphere is given as 180°(1 + 4x), where x is the fraction of the sphere's surface that is enclosed by the triangle. For any positive value of x, which in each case exceeds 180°.

8 + (-5)
Answer: 3
Step-by-step explanation: 8 + (-5) is the same as saying 8 - 5 and 8-5 = 3
8 + (-5)
A negative and a positive make a negative therefore 8 + (-5) changes to
8 - 5
8 - 5 = 3

What is the equation of a line that is parallel to the line y = 5x – 1 and passes through the point (4, –3)? A. y = 5x + 19 B. y = –5x + 17 C. y = 5x – 23 D. y = –15x – 115
Answer:
y = 5x - 23
Step-by-step explanation:
Slope: 5
Point (4, - 3)
y-intercept: -3 - (5)(4)
= -3 -20 = -23
y = 5x - 23
What is the equation of the line parallel to y = -5x + 6 and passes through the point (6,-8)?
Answer:
y = -5x + 22 is the equation of our parallel line
Step-by-step explanation:
remember a parallel line will have the same slope.
So let's begin by using the equation above and substituting the points.
[tex]y = - 5x + b \\ - 8 = - 5(6) + b \\ - 8 = - 30 + b \\ 30 - 8 = b \\ b = 22[/tex]
therefore our parallel line would be
[tex]y = - 5x + 22[/tex]
