The fact that the temperature dropped means that the new value is smaller than the old one. So, we must subtract.

We also know how much it dropped, so we know how much we must subtract.

The new value is thus

$10 - 32 = -22$ F

A rational function g is given below. Find all values of a for which g(a)=16. g(x)=(4)/(x+1)+(20)/(x^(2)+2x+1)

aliina [53]

Answer:

a = 2/3

Step-by-step explanation:

(4(x+1) + 20 )/(x+1) = 16

4x + 4 + 20 = 16x + 16

12x = 8

x = 2/3

Please help! alg 1! I really need a explaintion fastttt

Gelneren [198K]

Answer:

y = -5x +10
(0, 10)
(1, 5)
see attached

Step-by-step explanation:

1. Subtract 5x from both sides to put the equation in slope-intercept form:

y = -5x +10

2. The y-intercept is the point corresponding to x=0. The y-value when x=0 is the constant in the equation: 10. Then the point is ...

(x, y) = (0, 10)

You may notice this is one of the points listed in part 4, and is also used in question 3.

3. The x-value computed is 1; the y-value computed is 5. The point is ...

(x, y) = (1, 5)

You may notice this is one of the points listed in part 4.

NEED HELP WITH A MATH QUESTION

Lady_Fox [76]

Answer:

$\dfrac{18}{5}$

Step-by-step explanation:

The picture shows three isosceles tirangles with the same legs. The base of each triangle is 12 units, 5x-3 units and 17 units.

Since the angles at vertex of each isosceles triangles are 27°, 28° and 29°, then the lengths of the bases satisfy the double inequality

15<5x-3<17

Add 3 to this inequality

15+3<5x-3+3<17+3

18<5x<20

Divide it by 5:

$\dfrac{18}{5}$

Zubin has two pieces of string. One piece is 36 inches long and the other is 48 inches long. He wants to cut them into equal pie

skelet666 [1.2K]

Answer:

12 pieces each:

$S_1 = 3\ in$

$S_2= 4\ in$

Step-by-step explanation:

Given

$S_1 = 36\ in$ -- first string

$S_2 = 48\ in$ --- second string

Required

Determine the number of equal pieces

To do this, we first calculate the HCF of the length of both pieces $(36\ and\ 48)$

$36 = 2 * 2 * 3 * 3$

$48 = 2 * 2 * 2 * 2 * 3$

$Common\ prime\ factors = 2, 2\ and\ 3$

The HCF is:

$HCF = 2 * 2 * 3$

$HCF = 12$

Hence, he can cut both strings to 12 pieces each

Recall that

$S_1 = 36\ in$

The first string can then be cut in to 3 inches each (i.e. 36/12)

$S_2 = 48\ in$

The first string can then be cut in to 4 inches each (i.e. 48/12)
