Write a linear equation representing the information shown in the table.

Mathematics
1 answer:
Paraphin [41]3 years ago
7 0

Answer:

C. y = ⁵/2x - 5

Step-by-step explanation:

The linear equation representing the information on the table can be expressed in the slope-intercept form as y = mx + b, where,

m = slope = change in y/change in x

b = y-intercept/initial value = the value of y when x is zero

✔️Find m using two pairs given, say (0, -5) and (2, 0):

slope (m) = (0 - (-5))/(2 - 0) = 5/2

m = ⁵/2

✔️Find b:

when x = 0, y = -5. Therefore, y-intercept, b, is -5

b = -5

✔️To write the equation, substitute m = ⁵/2 and b = -5 into y = mx + b

Thus:

y = ⁵/2x + (-5)

y = ⁵/2x - 5

your total savings varies inversely with the amount spent on Bill's. if your savings is $300 when your cost of Bill's are $65. W
tatyana61 [14]
Let S and B be savings and bills respectively. Then,
S α 1/B
S = k/B Where k = Constant.
When S = $300, B = 65

Then,
300 = k/65
k = 300*65 = 19500

Therefore,
For B = $145,

S= 19500/145 = $134.48

A student inscribes a triangle within a semicircle. What is the measure of ∠XYZ?
nata0808 [166]

Answer: a. 90°


Step-by-step explanation:

We know that the in a circle, the measure of an inscribed angle is half the measure of the central angle with the same intercepted arc.

In the problem∠XYZ is the inscribed angle

∠XYZ=\frac{1}{2}\ arc(XZ)

⇒ ∠XYZ=\frac{1}{2}\angle{XZ}

Since XZ is a diameter of the circle which is a line segment, thus ∠XZ=180°

∴ ∠XYZ=\frac{1}{2}180^{\circ}=90^{\circ}

∴ ∠XYZ=90^{\circ}

Therefore, a. 90° is the measure of ∠XYZ.

Which sampling method is MOST appropriate in estimating the average number of votes for each candidate in an election across a c
kaheart [24]

Answer:

B. Stratified sampling, because there are specific subgroups to investigate.

Step-by-step explanation:

Stratified Sampling is a sampling method and is used when the population has subgroups with different characteristics. Random sampling is applied in each of the sub-groups <em>proportional </em>to their size and then these samples <em>combined </em>together to create sample of the study.

Since there are three towns with people from different occupations ( retirees,business owners, office workers), it is better to use stratified sampling method.
