Try to subtitute y with 3x - 7
15x - 5y = 14
15x - 5(3x - 7) = 14
15x - 15x + 35 = 14
35 ≠ 14

What is71 3/4 over 100 as a decimal<br><br><br> pls explain
lora16 [44]

Answer:

3 71/100 = 3.71

Step-by-step explanation:

To convert this mixed number (fraction) to a decimal just follow these two steps:

Step 1: divide numerator (71) by the denominator (100): 71 ÷ 100 = 0.71

Step 2: add this value to the the integer part: 3 + 0.71 = 3.71. So,

3 71/100 = 3.71

Identify the slope and y-intercept of the line whose equation is given. write the y-intercept as an ordered pair. y = negative 2
PSYCHO15rus [73]

The line having the equation, y = -2x + 5, has a slope = -2, and y-intercept = (0, 5). Thus, <u>option A</u> is the best choice.

The slope of a line is the tangent of the angle that the line makes with the positive side of the x-axis.

The y-intercept of a line is the point at which the line intersects the y-axis.

The standard form of a line is <u>y = mx + b</u>, where m represents the slope of the line, and b represents its y-intercept.

In the question, we are asked to identify the slope and the y-intercept of the line whose equation is y = -2x + 5.

Comparing the given equation of the line, y = -2x + 5, with the standard equation of a line, y = mx + b, we can say that,

m = -2, and b = 5.

Representing b as an ordered pair, we get (0, 5), as b represents the y-intercept which is a point on the y-axis, where the x-coordinate is always equal to zero.

Thus, we get the slope = -2, and the y-intercept = (0, 5).

The option representing the answer is <u>option A</u>.

HELP
pentagon [3]

Answer:

First graph

Step-by-step explanation:

First off, the graph opens up because <em>a</em><em> </em>is positive. Second, the parent function of the quadratic graph is \displaystyle y = x^2,and the greater the WHOLE NUMBERS [vertical stretch (<em>a</em>)] get, the slimmer the parabola gets, and the more you increase the DEGREE evenly [anything ending in 0, 2, 4, 6, and\or 8], the more flat, U-shaped the parabola becomes.

I am joyous to assist you anytime.
