Two year olds have a median height of 35 inches and 12 year olds have a median height of 60inches. Generate an equation to describe height as a of age. A) H(a)= -2.5a + 30 B) H(a)= 2.5a + 35 C) H(a)= 2.5a - 30 D) H(a)= .4a - 12 E) H(a)= 2.5a + 30arrow_forward
- Determine the number of real-number solutions from the given graph of 4x + 5x +9 = 0. The equation has real-number solution(s). (Type an integer.) y=4x + 5x +9 [-5,5,- 10,40] Xscl = 1, Yscl = E Enter your answer in the answer box.arrow_forwardA farmer plans to fence in a rectangular pasture adjacent to a river (see figure below). The pasture must contain 180000 square meters. No fencing is needed along the river. The Constraint is an area of 180000 square meters. Write an equation for the area in terms of x and y. This is called the secondary equation. 180000 = square meters (secondary);arrow_forwardWrite an equation (a) in slope-intercept form and (b) in standard form for the line passing through (-3,6) and parallel to x+2y=7. a) The equation of the line in slope-intercept form is. (Type your answer in slope-intercept form. Use integers or fractions for any numbers in the equation.)arrow_forward
- Use these model equations: the linear equation y=0.225x+12.45, the quadratic equation y=0.0032(x-30)*2+19.2, and the exponential equation y=1.90(1,08)*x a) Graph each equation on the same grid. Please complete thetable of values. Graph each equation on the same grid. b) Which model is most reasonable? Explain your answerarrow_forwardGraph the equation f(x) = x - 4 in a rectangular coordinate system.arrow_forward
